Introduction: Those who master the White Paper will master R08

In the descriptive exam for the Professional Engineer Comprehensive Technical Management Department, there is a known tendency for important themes from the White Paper (especially the Ministry of Land, Infrastructure, Transport and Tourism White Paper) to appear in the following year's exam This is not a coincidence.

• Exam questions are finalized around May (exam is in July)

• The Ministry of Land, Infrastructure, Transport and Tourism White Paper is published in June (summarizing trends from the previous fiscal year)

• The cycle where policy themes presented in the previous year's version (R6) of the White Paper appear in the following year's exam (R7-R8)

This book is a practical application tool that thoroughly dissects the 7 major policy themes of the Ministry of Land, Infrastructure, Transport and Tourism White Paper R7 (published June 2025) for the Professional Engineer Comprehensive Technical Management R08 (conducted July 2026) descriptive exam preparation.

While the free articles on the site focus on "overview and summary," this book covers:

• Citation points from the original White Paper (numerical values and data tables)

• Basis for the probability of re-appearance in R08

• Mapping of similar questions from the past 5 years (R03-R07)

• 10 "replace with your own work" worksheets × 7 chapters = 70 questions

and is designed so that examinees 2 months before the exam can immediately incorporate it into their study plan.

Chapter 2 Infrastructure Aging × 5 Management (Economy × Safety)

R08 Re-appearance probability: 8.5/10

Basis for re-appearance probability

Checking the descriptive questions of the compulsory subjects over the past 10 years (FY2016-FY2025), questions related to "aging, maintenance, and renewal of social infrastructure" have appeared 5 times or more. Representative examples include "Strategic Maintenance of Social Capital" in FY2017, "Risk Management Related to Inspection, Diagnosis, and Evaluation of Facilities" in FY2018, "Preventive Maintenance Management in the Construction Field" in FY2020, "Maintenance Policy for Aging Facilities" in Compulsory Subject II-2 of FY2023, and "Optimization of Infrastructure Maintenance Costs" in Compulsory Subject I-2 of FY2024.

Since the Ministry of Land, Infrastructure, Transport and Tourism White Paper R7 has positioned "transition to preventive maintenance" as one of its policy pillars, it is highly probable that similar themes will appear in R08. This is because the policy descriptions in the white paper reflect the priority issues of government agencies, and the Comprehensive Technical Management exam tests an engineer's judgment ability regarding actual administrative issues.

Citation points from the original White Paper R7

The 2025 White Paper on Land, Infrastructure, Transport and Tourism presents the following figures regarding the current status of and countermeasures for aging infrastructure.

Key Data

• Cost reduction effect of maintenance and renewal: Approximately 30% reduction over the next 30 years (estimate based on a shift from corrective maintenance to preventive maintenance)

• Number of road bridges under management: Approximately 730,000 bridges (mandatory close visual inspection every 5 years)

• Number of road tunnels under management: Approximately 10,000 tunnels (same as above; the Sasago Tunnel collapse accident was the catalyst for legislation)

• Bridges determined to require measures by the next inspection: Approximately 70,000 bridges nationwide (results of the first round of inspections, 2014–2018)

• Road cave-in accident (January 2025): Yashio City, Saitama Prefecture (caused by damage to sewer pipes; a nationwide special priority survey was requested)

The figure of a '30% reduction' can be used as a basis for quantitatively demonstrating the benefits of economic management in a thesis. However, you must always include the condition of 'cumulative maintenance and renewal costs over 30 years.' You should be able to recognize that the argument contrasting short-term cost increases (upfront investment in inspection and repair costs) with long-term cost reductions is the very concept of LCC (Life Cycle Cost).

Structure of the 5 Management Trade-offs

In a thesis on the theme of aging infrastructure, develop your argument around the main axis pair of Economic Management × Safety Management. The reality of the conflict is 'decision-making under budget constraints.'

Main axis pair: Economic Management × Safety Management

While preventive maintenance improves safety, it increases the short-term financial burden. If inspections, diagnostics, and repairs are carried out systematically, the risk of collapse decreases, but temporary budget overruns occur. In reality, especially in small municipalities, there are situations where even if they want to prioritize preventive maintenance, they lack the financial resources.

When writing about this trade-off in a thesis, it is advantageous for grading to adopt a stance of 'designing a solution that can maximize both' rather than 'choosing one or the other.' The three frameworks of the ALARP principle, RBM, and LCC, described later, function as such solutions.

Sub-pair 1: Economic Management × Human Resource Management

There is a shortage of engineers in local governments to handle inspections and diagnostics. The structure is one where technical knowledge accumulated over years is lost due to retirement, and outsourcing costs inflate. The challenge is to design a system (outsourcing, regional cooperation, and technical succession) that breaks the negative spiral of 'insufficient engineers leads to delayed inspections, which leads to delayed discovery of deterioration, which leads to skyrocketing corrective maintenance costs.'

Sub-pair 2: Safety Management × Social Environment Management

When repairing or updating aging infrastructure, traffic regulations, noise, and changes in landscape during construction affect local residents and the regional economy. You should also be aware of the trade-off that 'construction for safety creates negative externalities for the local community' as a secondary axis.

Concrete thesis development of solution frameworks

ALARP Principle (As Low As Reasonably Practicable)

The ALARP principle is a concept of 'reducing risk to as low as reasonably practicable.' Attempting to reduce risk to 'zero' would result in infinite costs. ALARP divides risk levels into three layers: 'unacceptable region,' 'ALARP region,' and 'broadly acceptable region,' and in the ALARP region, it requires that 'the risk be reduced to a level where the cost of additional measures is not grossly disproportionate to the benefits.'

How to use in an essay: Taking as an example a bridge judged in an inspection as being in a 'state requiring measures before the next inspection,' if you write, 'To keep the collapse risk within the ALARP region, reinforcement work will be carried out over a three-year plan. It was judged that the reinforcement cost is not grossly disproportionate compared to the human and social losses caused by a collapse,' it functions as a basis for safety management decisions.

Risk-Based Maintenance (RBM)

RBM is a method that determines priority using a two-axis matrix of 'degree of deterioration' and 'facility importance (risk impact)' to concentrate budget on high-risk locations.

Degree of deterioration: Health index determined by inspection (4 categories from I to IV)
Importance: Social impact in the event of collapse, such as traffic volume, presence of alternative routes, and population behind the facility

By prioritizing the repair of facilities with 'deterioration level III or higher and high importance,' the effect of ensuring safety can be maximized with a limited budget. The fact that economic management (efficiency of budget allocation) and safety management (risk reduction) are aligned within the same framework is the greatest strength of RBM in an essay.

LCC (Life Cycle Cost)

LCC is a concept that evaluates investment validity based on cumulative costs across all phases of 'design, construction, maintenance, renewal, and disposal.'

When comparing preventive maintenance vs. corrective maintenance using LCC, it is often the case that 'upfront investment in inspection and repair < emergency repair, compensation for damages, and social losses after a collapse.' The estimate in the White Paper of a '30% reduction over 30 years' is precisely a calculation from an LCC perspective.

How to use in an essay: You can justify economic management decisions with a framework such as, 'In an LCC analysis for a bridge in service for 60 years, the cost of preventive maintenance is about 30% lower than that of corrective maintenance. We will accept a short-term budget increase and prioritize a 30-year cumulative cost reduction.'

Past Exam Application Passport

• R05 Compulsory Subject II-2 — Maintenance Policy and Priority Setting for Aging Facilities: RBM two-axis matrix + ALARP application is directly effective

• R06 Compulsory Subject I-2 — Optimization of Infrastructure Maintenance Costs: LCC 30-year cumulative comparison framework is the core

• H30 Compulsory Subject — Risk Management of Inspection, Diagnosis, and Evaluation: ALARP three-layer structure + setting of risk acceptance levels

• R02 Compulsory Subject — Promotion Measures for Preventive Maintenance Management: Cost-benefit analysis of shifting from corrective maintenance to preventive maintenance

Tips for Structuring an Essay

The following is a framework for applying this to a descriptive Subject II-2 (two-stage structure of issues → measures).

Paragraph 1: Recognition of the current situation and the location of the problem
'Out of approximately 730,000 road bridges, about 70,000 are in a state requiring measures before the next inspection, and the risk of collapse due to aging is increasing (MLIT White Paper R7). On the other hand, while the shift to preventive maintenance brings a cost reduction effect of about 30% over 30 years, short-term increases in fiscal burden and a shortage of engineers in local governments are barriers.'

Paragraph 2: Clarification of trade-offs
'In this task, economic management (budget constraints, LCC optimization) and safety management (collapse risk reduction) conflict. In addition, the impact of repair work on local life (social environment management) and the securing of inspection engineers (human resource management) are intertwined as secondary axes.'

Paragraph 3: Development of solutions
'Using RBM, we will set priorities based on the facility's degree of deterioration and importance, and concentrate limited budgets on high-risk facilities. Based on the ALARP principle, we will evaluate cost-effectiveness from an LCC perspective while maintaining collapse risk within the ALARP region. By consolidating construction timing and collaborating with regional local governments, we will simultaneously suppress the shortage of engineers and the impact on the social environment.'

Paragraph 4: Residual Risk and Continuous Monitoring
Even after prioritization using RBM, the risk of deterioration progression in low-priority facilities remains. We will build a mechanism to dynamically review priorities by introducing monitoring sensors and updating annual inspection data.

Chapter 3 Construction Industry 2024 Problem (Human Resources × Economy)

R08 Re-appearance probability: 9.0/10

Basis for re-appearance probability

The 2024 problem (overtime work regulations, labor shortages, and logistics tightening) has been a related question for three consecutive years: R05, R06, and R07. In R06 Compulsory Subject II-1, the theme was 'Work Style Reform and Productivity Improvement in the Construction Industry,' and in R07 Compulsory Subject I-2, 'Labor Shortages and Sustainability of the Construction Industry' was confirmed as the theme.

In addition, institutional changes are concentrated, such as the application of overtime work caps to the construction industry in April 2024 and the enactment of the 'Third Act on Construction Industry Laborers' in June 2024. R08 is the perfect time to ask about 'the actual situation and response after the regulation enforcement,' and I judge the probability of it being asked again to be 9.0/10.

Citation points from the original White Paper R7

Key Data

• Percentage of construction workers aged 55 and over: 36.7% (about 4 points higher than the all-industry average of 32.4%)

• Percentage of construction workers aged 29 and under: 11.7% (about 5 points lower than the all-industry average of 16.9%)

• Average annual working hours in the construction industry: 2,018 hours (62 hours longer than other industries)

• Shortage of transport capacity for truck drivers: Approximately 34% in 2030 (already about 14% short as of 2024)

• Enactment of the Third Act on Construction Industry Laborers: June 2024 (institutionalized appropriate securing of labor costs and prohibition of low estimates)

• i-Construction 2.0 Goals: 30% labor saving and 1.5 times productivity by fiscal year 2040 (national goal for digitalization and automation)

The combination of '36.7% aged 55+ / 11.7% aged 29-' clearly illustrates the 'double population problem' where aging and the departure of the younger generation are progressing simultaneously. It is effective when you want to express the 'structural severity of the labor shortage' in a single phrase in a paper.

'2,018 hours per year' should be used in combination with a comparison to other industries (62 hours excess). While the magnitude is hard to convey with the number alone, it is possible to develop an argument that 'if a two-day weekend is realized, it calculates to a reduction of 260 hours, achieving both improved quality of life and reduced accident risk.'

Structure of 5 Management Trade-offs

Main Axis Pair: Human Resource Management × Economic Management

To realize a reduction in working hours (two-day weekends, interval between shifts), either work efficiency must be improved or additional personnel must be added. However, the construction industry has a chronic labor shortage, and adding personnel leads to increased costs. If productivity is increased through ICT construction or BIM/CIM, the human burden can be reduced, but the initial introduction cost is heavy.

This conflict between 'improving the work environment vs. ensuring profitability' is the reality of the main axis pair.

Sub-pair 1: Safety Management × Human Resource Management

Long working hours and chronic fatigue are breeding grounds for human error. The number of deaths from occupational accidents in the construction industry remains at the highest level among all industries, and decreased attention due to accumulated fatigue is directly linked to accident rates. The causal chain of 'reducing overtime work → reducing fatigue → lowering accident risk' is a rare example where safety management and human resource management point in the same direction. While it does not look like a trade-off at first glance, it is necessary to be careful that a new fatigue peak may be created in the process of consolidating and compressing night and holiday work to realize a two-day weekend.

Sub-pair 2: Information Management × Human Resource Management

The introduction of i-Construction 2.0 and CCUS (Construction Career Up System) requires digital skills. Additional education (reskilling) for older skilled workers who are unfamiliar with IT becomes necessary, and learning costs and temporary productivity declines increase the burden on human resources.

Concrete Thesis Development for Solution Frameworks

Evaluation Shift as Human Capital Investment

Education and training expenses in the construction industry (training for skilled workers and support for acquiring qualifications) have traditionally been recorded as "expenses (costs)." However, based on human capital theory, educational investment is an investment that generates "revenue" in the form of future productivity improvement, prevention of turnover, and reduction of accident costs.

How to use in a thesis: A structure such as "Transitioning to a work system that fits within 40 hours per week will reduce construction capacity in the short term. To mitigate this impact, evaluate the education budget over a 3-5 year span as a human capital investment combining OJT and OFF-JT, and use the achievement of 1.5x productivity (i-Construction 2.0 goal) as the basis for economic recovery" is effective.

Inter-shift Rest Period System

In the EU, a "rest period of at least 11 hours between the end of work and the start of the next shift" is mandatory, and in Japan, it became a duty of effort in 2023. In the construction industry, there are many cases where early morning work and overtime overlap, and there are sites where the actual rest time is only 6 to 8 hours.

How to use in a thesis: By setting the observance of an 11-hour or more inter-shift rest period as a rule for the entire site, physical fatigue accumulation is suppressed. By writing that "this is a response to the upper limit regulation (45 hours per month, 360 hours per year) and at the same time a safety management measure that structurally prevents labor accidents caused by human error," it can be shown that the sub-pair of human resource management and safety management can be solved with a single measure.

Collaboration between ICT Construction (i-Construction 2.0) and CCUS

i-Construction 2.0 aims for a 30% labor saving and 1.5x productivity by 2040 through "utilization of 3D data, automated construction, and remote management." CCUS (Construction Career Up System) is a mechanism that registers the qualifications and work history of skilled workers across the industry, leading to the visualization of wage levels and improvement of working conditions.

Synergy effect of both: While promoting labor saving through ICT construction, if the treatment of high-skilled workers is visualized and wages are raised through CCUS, a structural transformation to a construction industry where "one can work with high wages even with fewer people" will progress. This is the fundamental answer to the shortage of successors.

Leveling of Construction Periods

Due to the "March concentration" problem where construction orders are concentrated at the end of the fiscal year, the difference between busy and slack periods in the construction industry is extreme. Excessive overtime accumulates during busy periods, and operating rates drop during slack periods, making management unstable. "Leveling orders," where the ordering party (national/local government) spreads the ordering period throughout the year, is an institutional infrastructure that supports both the reduction of overtime and the improvement of productivity.

Past Exam Application Passport

• R07 Compulsory Subject I-2 — Labor Shortage and Sustainability of the Construction Industry: CCUS + Leveling orders + i-Construction 2.0 target figures

• R05 Compulsory Subject II-1 — Measures for Securing and Developing Successors: Human capital investment framework + Reskilling measures

Tips for Structuring the Thesis Outline

Paragraph 1: Recognition of the Current Situation
"In the construction industry, aging is progressing with 36.7% being 55 years old or older, while those 29 years old or younger remain at only 11.7%, making the shortage of successors serious (Ministry of Land, Infrastructure, Transport and Tourism White Paper R7). The annual working hours of 2,018 hours are 62 hours longer than in other industries, and the reorganization of the on-site production system is an urgent task due to the application of the upper limit regulation in April 2024."

Paragraph 2: Clarification of Trade-offs
"Reduction of overtime (human resource management) leads to a decrease in construction efficiency, creating a conflict with economic management due to the addition of personnel. At the same time, there is a sub-axis of safety management where long working hours increase the risk of labor accidents through chronic fatigue."

Paragraph 3: Development of Solutions
"Aim for 30% labor saving with ICT construction of i-Construction 2.0, and use CCUS to improve the treatment and retention rate of skilled workers. Thoroughly implement an 11-hour or more inter-shift rest period as a site rule to physically suppress the risk of accidents caused by fatigue. Structurally eliminate excessive overtime during busy periods through leveled ordering in cooperation with the ordering party."

Paragraph 4: Residual Risk and Continuous Monitoring
“Even after the introduction of ICT, non-digital tasks remain, and there is a risk that the productivity of older skilled workers will temporarily decline. We will continue digital skill training through off-the-job training (OFF-JT) and monitor improvement status by measuring productivity at least once a year.”

General Contractor Perspective — 5-year set included in R07 "Labor Shortage × Automated Construction Machinery"

Chapter 4: Acceptance of Foreign Human Resources (Safety × Human Resources)

R08 Re-appearance Probability: 7.0/10

Basis for re-appearance probability

The utilization of foreign human resources is a "new theme" for which there are limited precedents of direct questions in past Professional Engineer Comprehensive Technical Management descriptive exams. However, because it is a cross-cutting theme closely intertwined with the 2024 problem, aging infrastructure, and i-Construction 2.0, it is increasingly being described as part of a thesis in a "supplementary" position.

Since the three laws on human resources established in June 2024 also mention 'improving the treatment of foreign skilled workers' and the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has clarified the projected number of accepted Specified Skilled Workers, it has become highly likely that this will appear as an independent theme in R08. The high level of social attention (revision of the Immigration Control Act and expansion of Specified Skilled Worker ii) is also a factor for additional points.

Note that since there are no past exam questions that directly correspond to the 'Past Exam Application Passport' at this time, please read this chapter from the perspective of 'anticipating the outline of a thesis for a new theme'.

Citation points from the original MLIT White Paper R7

Key Data

• Projected acceptance of Specified Skilled Workers (under MLIT jurisdiction): Approximately 181,000 people at most over the five years from FY2024 to FY2028 (MLIT 'Basic Policy on the Operation of the Specified Skilled Worker System', total for multiple fields including construction, shipbuilding, and automobile maintenance)

• Percentage of construction workers aged 55 and over: 36.7% (indicating mass retirement in the near future due to aging)

• Percentage of construction workers aged 29 and under: 11.7% (indicating the departure of domestic youth from the construction industry)

• Number of CCUS registered skilled workers: Approximately 1.3 million (CCUS official statistics, as of FY2024. Employment history of foreign skilled workers is also subject to registration)

• Three laws on human resources (third revision): Established in June 2024 (institutionalized the appropriate securing of labor costs including those for foreign nationals)

The projected acceptance number of 'approximately 181,000 in 5 years' is a very large figure. It can be read as meaning that foreign human resources equivalent to 6% of the total number of construction skilled workers (approximately 3 million) will flow in over 5 years. This does not stop at 'quantitative replenishment of labor' but simultaneously creates qualitative challenges such as 'safety management, communication, and social integration'.

Structure of the 5 Management Trade-offs

Main Axis Pair: Safety Management × Human Resource Management

Foreign skilled workers start from a different level of Japanese language ability, safety knowledge, and familiarity with on-site practices compared to domestic skilled workers. In particular, there is a risk that risk recognition will be delayed because the 'tacit knowledge' of the site (KY activities, unspoken understanding, non-verbal communication) is not conveyed.

'Accepting foreign human resources (satisfying human resource management)' and 'maintaining safety standards (ensuring safety management)' conflict without an adequate education system. Investing time and cost in safety education, language support, and cultural adaptation support is the only path to resolving this conflict.

Sub-pair 1: Economic Management × Human Resource Management

Accepting foreign skilled workers incurs initial costs not found in domestic hiring, such as visa application procedures, housing provision, Japanese language education, safety training, and living support. If these costs are recorded as 'single-year expenses', it looks like an economic deterioration, but if evaluated as human capital investment over a 3-5 year span, the benefits of resolving labor shortages often outweigh them.

Sub-pair 2: Social Environment Management × Human Resource Management

The dormitories and living foundations of foreign skilled workers affect local communities. In situations where cultural friction, coexistence with local residents, and multicultural coexistence measures are required, the perspective of social environment management is necessary. Also, if the labor protection standards of the sending country differ from those of Japan, ethical risks in the supply chain will also arise.

Concrete Thesis Development for Solution Framework

KY training utilizing VR/AR

KY (Hazard Prediction) at construction sites is conveyed more effectively through visuals and physical experience than through language. By utilizing VR technology, it is possible to provide safety training that transcends language barriers by allowing workers to experience hazardous environments, such as high places, areas around heavy machinery, and confined spaces, in a virtual space. Using AR (Augmented Reality), hazard information can be overlaid in multiple languages at specific points on the site.

How to use in an essay: 'By introducing VR-based KY training for foreign skilled workers, we can enable them to acquire hazard recognition skills without relying on language. While the initial investment is XX0,000 yen per year for equipment purchase and training design, the benefits clearly outweigh the costs when compared to the loss per labor accident (several million to tens of millions of yen, including direct and indirect costs) (ALARP judgment),' which also aligns with economic management.

Multilingual Support and Universal Design (Pictograms)

Multilingualizing safety signs, work procedures, and emergency evacuation routes is the basic infrastructure for ensuring the safety of foreign skilled workers. In particular, pictograms (graphic symbols) are a design philosophy that conveys meaning regardless of language, and their development for construction sites is progressing under the Japanese Industrial Standards (JIS).

By utilizing wearable translators (smartwatch or earphone types), supervisors and skilled workers can communicate in multiple languages in real time. Removing daily communication barriers leads to the early sharing of near-miss incidents and accident prevention.

Intervals Between Shifts and Compliance Management

Foreign skilled workers are required to 'work in compliance with laws and regulations' as a condition of their residence status. Observing an interval of 11 hours or more between shifts also functions as a way to ensure compliance with the Labor Standards Act and the Immigration Control Act. There is also a management risk that overwork increases the risk of illegal overstaying and disappearance (due to the accumulation of dissatisfaction with working conditions).

How to use in an essay: 'Observing intervals between shifts functions as a measure that simultaneously achieves three management goals: fatigue management for foreign skilled workers (safety management), maintenance of residence status (information management), and reduction of disappearance risk (human resource management).' Demonstrating such multifaceted effects allows one to express the integrated perspective of multiple management areas typical of a Professional Engineer (General Manager).

Visualization of Capabilities and Improvement of Treatment through CCUS

CCUS is also applied to foreign skilled workers, and their work history, acquired qualifications, and training records are recorded across the industry. A mechanism that allows accumulated achievements to be used for wage negotiations, the next residence status renewal, and screening for transition to Specified Skilled Worker (ii) ensures a structure where foreign skilled workers can build a career rather than being 'disposable'.

From the perspective of human resource management, this is directly linked to a long-term investment strategy of 'nurturing and retaining the talent we have hired'.

Past Exam Application Passport

This chapter is a new theme for which there is no directly corresponding past exam question, but it can be incorporated into essays as a 'supplementary discussion' for the following questions.

• R07 Compulsory Subject I-2 — Labor Shortage and Sustainability of the Construction Industry: Mention foreign human resources as a means of securing workers

• R06 Compulsory Subject II-1 — Work Style Reform in the Construction Industry: Incorporate multilingual support and intervals between shifts as one of the measures

• R05 Compulsory Subject II-1 — Securing and Developing Human Resources: Position VR safety education and CCUS as development measures

Tips for Structuring the Essay Outline

Paragraph 1: Recognition of the Current Situation
'In the fields under the jurisdiction of the Ministry of Land, Infrastructure, Transport and Tourism for the Specified Skilled Worker system, the acceptance of up to approximately 181,000 people is expected over the five years from fiscal 2024 to 2028 (Ministry of Land, Infrastructure, Transport and Tourism White Paper R7). Considering the structural shortage of workers in the construction industry, where 36.7% are 55 or older and 11.7% are 29 or younger, the utilization of foreign human resources has become an essential measure, not an option.'

Paragraph 2: Clarification of Trade-offs
'While accepting foreign human resources resolves the labor shortage (human resource management), there is a risk that the safety level of the site will decline due to differences in language, culture, and safety practices (safety management). In addition, the secondary axis of economic management, which is the cost of acceptance, and the secondary axis of social environment management, which is coexistence with the local community, are intertwined.'

Paragraph 3: Development of Solutions
'Implement safety education that transcends language barriers through VR/AR-based KY training, and remove daily communication barriers through multilingualization using pictograms and wearable translators. Make the observance of an 11-hour interval between shifts a site rule to simultaneously suppress fatigue-related accidents and the risk of legal violations. Visualize work achievements with CCUS to promote improved treatment and long-term retention.'

Paragraph 4: Residual Risk and Continuous Monitoring
“There are individual differences in the effectiveness of safety training, and technical communication with workers who have low Japanese proficiency remains a challenge. By aggregating monthly near-miss reports and analyzing incidents by foreign worker, we will establish a system to identify high-risk individuals and work processes early and implement additional training.”

General Contractor Perspective — 5-year set as an adjacent issue to addressing labor shortages

Chapter 5: GX and Carbon Neutrality (Economic Efficiency × Social Environment)

5-1. Citation Points from the Original White Paper R7

The 2025 Ministry of Land, Infrastructure, Transport and Tourism White Paper sets the 2050 carbon neutrality (net-zero) as a major goal, with an intermediate milestone of reducing greenhouse gas emissions by 46% by fiscal year 2030 compared to fiscal year 2013. The following four points are particularly noteworthy as measures in the construction sector.

1. GX Construction Machinery Certification System (Established in October 2023)

A system in which the government certifies the introduction of low-carbon construction machinery, such as electric or hydrogen-powered equipment, and provides incentives. The goal is to directly reduce CO2 emissions during construction by deploying certified models to work sites. At this stage, the number of certified models is limited, and industry estimates indicate that the cost premium is approximately 1.5-2.5 times that of conventional machinery (based on MLIT GX Construction Machinery Certification System publication materials and machinery manufacturer estimates), which acts as an economic barrier.

2. New Modal Shift

In addition to shifting freight to railways and ships (conventional modal shift), the government promotes the optimal combination of all transport modes, including land, sea, and air, such as double-trailer trucks, automated logistics roads, and drone delivery. In the construction industry, the review of material and surplus soil transport is a direct scope.

3. Blue Carbon

Frameworks are being developed to account for carbon absorbed by marine ecosystems (seaweed beds, tidal flats, mangroves, etc.) as carbon offsets. This can be utilized as a means to offset residual emissions in combination with coastal and port construction projects.

4. Revision of the Basic Plan for Water Cycle (August 2024)

The integrated and sustainable reconstruction of water supply and sewerage systems has been positioned as a priority. Emission reductions in the long-term operation of water infrastructure (such as energy conservation in pump equipment) are linked to the conservation of the water cycle as green infrastructure.

These policy groups structurally contain the question of 'how to maximize emission reductions within an economically feasible range,' and the foundation is set for testing the tension between economic management and social environment management in the Chief Engineer examination.

5-2. 5 Management Trade-offs Details

Main Axis: Economic Management × Social Environment Management

For each issue, we will organize the requirements of both management types and the essence of their conflict.

• Introduction of GX Construction Machinery

  • Economic Management Requirement: Want to suppress the price difference compared to conventional machinery (1.5-2.5 times, based on MLIT/manufacturer industry estimates)

  • Social Environment Management Requirement: Want to reduce CO2 emissions immediately

  • Essence of Conflict: Mismatch in time horizon between initial costs vs. social benefits

• Carbon Pricing

  • Economic Management Requirement: Carbon taxes and emissions trading increase business costs

  • Social Environment Management Requirement: Market signals will not function unless external diseconomies are internalized

  • Essence of Conflict: Short-term profitability vs. long-term environmental consistency

• New Modal Shift

  • Requirement for Economic Management: Transport cost and time fluctuation risks arise

  • Requirement for Social Environment Management: Transport-originated CO2 can be significantly reduced

  • Essence of Conflict: Logistics efficiency vs. Decarbonization effect

• LCA Application

  • Requirement for Economic Management: Increase in costs and time for full-process evaluation

  • Requirement for Social Environment Management: Hidden environmental impacts that were previously invisible can be made visible

  • Essence of Conflict: Evaluation cost vs. Decision-making accuracy

Sub-axis 1: Safety Management × Social Environment Management

New energy construction machinery (electric/hydrogen) brings new types of safety hazards to the site, such as the installation of charging and hydrogen refueling equipment, electric shock risks from high-voltage systems, and hydrogen leakage/explosion risks. The current situation is that the development of safety regulations is lagging behind the spread of technology.

Sub-axis 2: Information Management × Social Environment Management

Power consumption by data centers is surging (related estimates in the Ministry of Economy, Trade and Industry's "Semiconductor and Digital Industry Strategy" project that it will account for 10-15% of domestic power consumption by 2030). When aiming for both construction efficiency and carbon reduction through ICT/DX, a paradox arises where the emissions of the IT infrastructure itself increase. Visualization and management of Scope 2 and Scope 3 emissions are required.

5-3. Tips for Thesis Development (E-C-R Model)

For a GX theme thesis, consistency can be achieved in the answer by developing it using the E-C-R model (External cost → Carbon pricing → Risk-adjusted LCA).

E: Explicit statement of external diseconomies (External cost)

Explicitly state at the beginning that carbon emissions are external diseconomies not reflected in market prices. By establishing the logic that "1 ton of CO2 emission shifts a cost of XX yen to society as future climate change damage," provide the basis for why the conflict between economic management and social environment management arises.

C: Internalization through carbon pricing (Carbon pricing)

Position carbon pricing (carbon tax/emissions trading) as a means to internalize external diseconomies. While acknowledging the cost increase, present it as a "justification for pursuing the optimal solution for society as a whole." In the thesis, you can describe "gradual carbon price increases and the design of incentives for corporate technology investment" as countermeasures.

R: Risk-adjusted LCA evaluation (Risk-adjusted LCA)

Show a scenario where the initial cost premium of GX construction machinery becomes superior to conventional machinery when re-evaluated from an LCA perspective (including environmental costs for all processes). At the same time, explicitly state the safety risks that arise during the early adoption phase of new technology as residual risks, and demonstrate a stance of managing them through a phased introduction plan (PoC → Pilot site → Company-wide deployment).

With these 3 steps, you can satisfy the standard structure of a comprehensive management thesis: "Problem statement (essence of conflict) → Logical basis for solutions → Management of residual risks."

5-4. R08 Re-appearance Probability and Basis

Re-appearance probability: 8.0/10

• White Paper Frequency: Carbon neutrality is featured as a priority chapter in the R5, R6, and R7 editions

• Past Exam Record: R04 Compulsory Subject I featured 'Decarbonization and Business Continuity', R05 featured modal shift-related topics, and R06 featured the CN theme

• Social Attention: Supported by the GX Promotion Basic Policy (Cabinet decision in February 2023) and the GX Decarbonization Power Supply Act (enacted in May 2023)

• Examiner's Intent: 'Economy vs. Environment' is the easiest pair to question in the Comprehensive Technical Management 5-management trade-off exam

• Unresolved Nature: Progress toward the 2030 46% reduction target is still halfway, and social tension continues

While it does not reach the level of i-Construction 2.0 (9.5/10) or the 2024 Construction Industry Problem (9.0/10), many examinees choose it as their first-choice theme due to the 'ease of setting the main axis pair' and the 'abundance of concrete measures (GX construction machinery, LCA)'.

5-5. Past Exam Application Passport

• R04 Compulsory Subject I — 'Challenges for the Construction Industry Toward Realizing a Decarbonized Society': GX construction machinery, LCA, and carbon pricing can be applied directly

• R05 Compulsory Subject I — 'Efforts in the Transport Sector Toward Carbon Neutrality': New modal shift (rail, marine, double-linked trucks) is the core

• R06 Compulsory Subject II — 'Compatibility of Environmental Load Reduction and Business Costs': After organizing the conflict structure with the E-C-R model, evaluate using LCA

• R07 Elective Subject III — 'Risk Management Associated with the Introduction of GX Construction Machinery': Address with a secondary axis of Safety Management × Social Environmental Management

Chapter 6: i-Construction 2.0 (Economy × Information)

6-1. Citation points from the original White Paper R7

'i-Construction 2.0' in the 2025 MLIT White Paper is the most important DX policy, setting a goal to reduce labor on construction sites by at least 30% and improve productivity by 1.5 times by fiscal year 2040. The following five original data points can be used directly in essays.

1. Three types of automation

The three pillars are 'Construction Automation,' 'Data Linkage Automation,' and 'Construction Management Automation.' The goal is end-to-end automation, from automation at the construction stage (automatic grading and compaction using TS/GNSS) to data linkage (consistent flow of information from design to construction to maintenance via BIM/CIM) and remote/automated construction management (real-time verification of completed work using cameras and sensors).

2. 3D City Model 'PLATEAU' developed in approximately 250 cities nationwide

Develop 3D digital twins of urban spaces on a national scale to be used for disaster prevention simulations, urban development DX, and advanced infrastructure inspection. It also functions as a consensus-building tool during the planning phase of construction projects.

3. Automated Logistics Roads (Phase 1 operation to start by the mid-2030s)

A concept to provide dedicated lanes in areas such as highway medians for unmanned transport of goods by automated vehicles. While it has the potential to dramatically compress the transport costs and time for construction materials, development costs and competition with existing logistics operators remain as challenges.

4. Vehicle Dispatch Optimization via Quantum Computing

Research and development is progressing on applying quantum annealing to high-speed analysis of vast delivery route candidates for the optimization of construction logistics and distribution. While there are limits to scaling up at the current stage, implementation from the 2030s onward is in sight.

5. Level 4 Autonomous Buses and Automated Construction at Naruse Dam

Automated compaction and remote construction at Naruse Dam (Akita Prefecture) represent the first large-scale implementation case in Japan. Level 4 autonomous bus operations have also begun in some regions. These are not "pie in the sky" concepts but serve as valid evidence as real-world implementation examples presented in the White Paper.

6-2. Details of 5 Management Trade-offs

Main Axis: Economic Management × Information Management

For each issue, we will organize the requirements of both management types and the essence of their conflict.

• Full-scale BIM/CIM Introduction

  • Economic Management Requirement: Implementation and training costs strain the single-year budget

  • Information Management Requirement: Consistent data flow can reduce design changes and rework

  • Essence of Conflict: Weight of initial investment vs. medium-to-long-term cost reduction

• SaaS/Cloud Utilization

  • Economic Management Requirement: Continuous subscription fees become fixed costs

  • Information Management Requirement: Can achieve higher functionality at a lower cost than on-premises

  • Essence of Conflict: Ease of withdrawal (option value) vs. running costs

• Sensor/IoT Integration

  • Economic Management Requirement: Device and communication costs increase

  • Information Management Requirement: Real-time visualization of finished work and quality data is possible

  • Essence of Conflict: Measurement costs vs. reduction of rework risk

• Data Sharing and Collaboration

  • Economic Management Requirement: Proliferation of proprietary systems leads to high integration costs

  • Information Management Requirement: Standardization of open data improves cross-industry efficiency

  • Essence of Conflict: Sunk costs of system investment vs. interoperability

Sub-axis 1: Safety Management × Information Management

As automation and remote construction progress, the risk of construction stoppage due to cyberattacks or system failures becomes apparent. Unlike IT security, OT (Operational Technology) security has the characteristics of "prioritizing availability and difficulty in updating." While network connectivity at construction sites increases convenience, it also creates risks of remote manipulation or construction data tampering by malicious third parties.

Sub-axis 2: Human Resource Management × Information Management

i-Construction 2.0 assumes the reskilling of on-site workers (acquiring surveying, ICT operation, and data analysis skills). At sites with many skilled workers unfamiliar with digital technology, proficiency gaps can be a root cause of safety accidents. Furthermore, the mismatch between work processes rendered unnecessary by ICT and those newly required creates short-term inefficiency in human resources.

6-3. Tips for Developing Essays (P-S-R Model)

Essays on the i-Construction 2.0 theme are easier to organize when developed using the P-S-R model (PoC → Scale-up → Residual risk).

P: Threshold Verification via Proof of Concept (PoC)

Simultaneous deployment across the entire company or all sites carries high economic risk. Conduct a PoC at one site for one type of work, and make deployment decisions only after confirming that labor-saving rates, productivity improvement rates, and cost recovery periods exceed target thresholds. The stance of "avoiding full-scale deployment without verification" can be justified from the perspective of economic management.

S: Scaling Up via SaaS Utilization

When deploying company-wide based on PoC results, choose SaaS or subscription-based cloud services rather than fixed investments in on-premise systems. Securing "option value"—the ability to withdraw or switch as needed while keeping initial investment low—is a rational decision from the perspective of information management.

R: Management of Residual Risk

As residual risks that remain even after promoting automation and ICT, clearly state the following three points: (1) construction stoppage due to cyberattacks or system failures, (2) operational errors by workers who have not completed reskilling, and (3) malfunctions under weather or geological conditions that could not be verified during the PoC. Accompany each with countermeasures (OT security/defense-in-depth, education and training plans, and manual backup procedures).

6-4. R08 Re-appearance Probability and Rationale

Re-appearance probability: 9.5/10 (Most important theme in this book)

• Consecutive Questions: DX, ICT, and i-Construction related topics have appeared for 4 consecutive years from R04 to R07

• White Paper Frequency: 'i-Construction 2.0' has been featured as a priority policy every year in the R5, R6, and R7 editions

• Current Policy Progress: 2024-2026 is clearly defined as a priority development period aimed at the 30% labor-saving target

• Ease of Grading: The conflict between economic efficiency and information is a structure that examiners prefer, as it makes it easy to set evaluation criteria

• Social Sense of Crisis: Directly linked to the 2024 construction industry problem (overtime work cap regulations), with DX positioned as the only solution

i-Construction 2.0 is the theme in Chapter 8 of this book where 'time spent on preparation is most directly reflected in the score.' This should be the chapter that all examinees prioritize first.

6-5. Past Exam Application Passport

• R04 Compulsory Subject I — 'DX/ICT in Construction Sites and Labor Productivity': The entire P-S-R model can be applied directly. Emphasizes the importance of PoC

• R05 Compulsory Subject I — 'Risks and Countermeasures Associated with Digitalization of Construction Technology': Developed using secondary axes (Safety × Information, Human × Information)

• R06 Compulsory Subject II — 'Organizational Challenges After Full Transition to BIM/CIM': Addressed by developing the S (SaaS/Scale-up) phase

• R07 Compulsory Subject I — 'Conditions for Realizing the 2040 30% Labor-Saving Target': Developed directly based on the R7 White Paper source (30% reduction, 1.5x productivity, 250 cities)

Application Procedure (for 3-minute brainstorming)

1. If the question includes any of 'DX, ICT, or Automation,' first confirm the main axis of 'Economic Efficiency vs. Information'

2. Use the White Paper figures (2040 30% labor-saving, 1.5x productivity, PLATEAU in approx. 250 cities) as the basis and place them at the beginning

3. Develop the 'Proof of Concept → Deployment → Residual Risks' flow in the P-S-R sequence

General Contractor Perspective — R04 'i-Construction DX Plan' / R03 'BIM/CIM Data Integration' included 5-year set

Chapter 7 Regional Infrastructure Group Management (Economy × Human Resources)

7-1. Citation points from the original White Paper R7

The 2025 MLIT White Paper selected 11 cases nationwide (40 local governments) in fiscal year 2023 as model regions for 'Regional Infrastructure Group Regeneration Strategy Management (Group Management)', promoting a method to break away from the traditional system of managing infrastructure individually and instead manage wide-area, multiple, and multi-sector infrastructure integrally as a 'group'.

Citation Point 1: Three 'Bundles'

• Bundle of Local Governments: Multiple municipalities collaborate to jointly order maintenance and management, realizing economies of scale. This allows small-scale municipalities to secure technical capabilities and budget scales that they could not procure on their own.

• Bundle of Business Operators: Comprehensively outsource multiple facilities and multiple industries, such as roads, bridges, tunnels, and water/sewerage, to the private sector. By consolidating various contracts, administrative costs for both the ordering party and the contractor can be reduced.

• Bundle of Engineers: Facilitate the wide-area interchange of technical staff between local governments to utilize specialized personnel unevenly distributed in specific municipalities across a wider area.

Citation Point 2: Specific Examples (Published in the White Paper)

• Tama City, Tokyo: Multi-year, comprehensive outsourcing of bridge maintenance and management to construction consultants (comprehensive private outsourcing)

• Kanagawa Prefecture Enterprise Agency: 10-year contract for the Hakone area waterworks business, outsourcing up to the 'drafting of the renewal plan' to the private sector (Water PPP Level 3.5)

• Hirata Village, Fukushima Prefecture: Residents perform daily inspections using the 'Bridge Log' app in a system with zero technical staff (resident-participatory maintenance)

Citation Point 3: Numerical Effects

By shifting from corrective maintenance to preventive maintenance, estimates show that cumulative maintenance costs over 30 years can be reduced by approximately 30%. This figure can be used repeatedly in papers as 'evidence demonstrating the economic rationality of group management'.

7-2. Details of 5 Management Trade-offs

Main Axis: Economic Management × Human Resource Management

For each issue, we will organize the requirements of both management types and the essence of their conflict.

• Comprehensive Private Outsourcing

  • Economic Management Requirement: Cost reduction, economies of scale, and administrative efficiency

  • Human Resource Management Requirement: Need to maintain technical judgment capabilities on the ordering side

  • Essence of Conflict: Economic benefits of outsourcing vs. risk of technical knowledge loss

• Wide-area Cooperation

  • Economic Management Requirement: Pro-rating costs and expanding scale through joint procurement

  • Human Resource Management Requirement: Increased decision-making costs for wide-area coordination

  • Essence of Conflict: Economies of scale vs. coordination costs and difficulty in reaching consensus

• Resident-participatory maintenance

  • Economic management requirement: Ability to maintain daily inspections at low cost

  • Human resource management requirement: Inability to fully manage resident safety (electric shock, falls, etc.)

  • Essence of conflict: Personnel cost reduction vs. risks of non-expert activities

• RBM (Risk-Based Management)

  • Economic management requirement: No budget to inspect all facilities

  • Human resource management requirement: Who bears the responsibility if high-risk areas are overlooked?

  • Essence of conflict: Cost-prioritized selection vs. safety comprehensiveness

Sub-axis 1: Economic Management × Safety Management

Shifting to preventive maintenance leads to long-term cost reduction, but increases inspection and repair costs in the short term. Especially in small municipalities, 'current fiscal year budget constraints' and 'avoidance of future risks' easily become a trade-off, creating a structure that tends toward corrective maintenance (fixing after failure).

Sub-axis 2: Safety Management × Human Resource Management

In municipalities with severe shortages of engineers, there is a lack of staff capable of accurately ordering and supervising bridge and tunnel inspection work. Resident participation and the use of ICT (drones, sensors) can be complementary measures, but there are limits to replacing professional judgment, and the risk remains that a decline in inspection quality will lead to safety issues.

7-3. Tips for Essay Development (G-P-C Model)

For essays on the theme of group management, the flow of arguments becomes natural when developed using the G-P-C model (Grouping → PPP/PFI → Community).

G: Creating economies of scale through grouping (Grouping)

Shift from a system of managing infrastructure as individual facilities to re-perceiving geographically and functionally related infrastructure as a 'group.' Present the three-layer grouping of municipal bundles, business operator bundles, and engineer bundles, and demonstrate the economic effects of each (centralization of ordering, wide-area utilization of human resources, and sharing of engineers).

P: Ensuring economic efficiency through comprehensive private outsourcing and PPP/PFI (PPP/PFI)

As the next step after grouping, utilize private sector management know-how, technical capabilities, and fundraising power. Water PPP (Level 3.5: private outsourcing up to the creation of the original plan) signifies a shift from the conventional 'design → order → construction' order-giver-led approach to 'goal-setting management.' This shift reduces the workload of the order-giver's staff while incorporating private sector technological innovation.

C: Complementing the remaining gap with resident participation (Community)

Daily visual inspections and abnormality reporting that cannot be covered even by a bundle of engineers are supplemented by the participation of local residents (e.g., Bridge Log). However, always include measures such as limiting the scope of activities and conducting safety education to manage the safety risks of residents. Finally, conclude the essay by clearly stating: 'Residual risk: Maintain a system where external experts always handle professional judgments (diagnosis, repair planning, etc.) that cannot be replaced by resident participation.'

7-4. R08 Re-appearance Probability and Basis

Re-appearance probability: 6.5/10

• White Paper Inclusion: The R7 edition newly includes specific figures for 11 group management cases across 40 municipalities. Topics with published figures are likely to appear on exams the following year.

• Novelty of the Theme: Since the selection of 11 cases nationwide was only completed in fiscal year 2023, it is highly likely that R08 will be the first time it is featured on the exam.

• Overlap with Other Themes: The background of the issues overlaps with infrastructure aging (8.5/10) and the Construction Industry 2024 problem (9.0/10), making it somewhat less likely that group management will be featured as a standalone question in the same year.

• Possibility of Combined Questions: In Compulsory Subject I, there is a possibility that group management, preventive maintenance, and PPP/PFI will be asked in combination as 'comprehensive management of aging countermeasures'.

Although the probability of it appearing is slightly lower compared to other themes, it is highly important as a Professional Engineer theme of 'Human Resources × Economic Efficiency,' and it is content that must be known as a supplementary point for other themes (PPP/PFI, wide-area cooperation).

7-5. Past Exam Application Passport

• R05 Compulsory Subject II — 'Restructuring of Maintenance and Management Systems for Local Governments': Directly addressed by combining the three 'bundles' and PPP/PFI.

7-6. Worksheet (Application to Own Work)

By answering the following 10 questions, you will complete a thesis outline that applies the content of this chapter to your own work. Please fill in the blanks with your own words.

1. Indicate the ratio of technical staff responsible for maintenance and management to the number of facilities managed (bridges, tunnels, water and sewage, etc.) in your own work (or the municipality your organization is involved with).

2. State the current status of the transition from 'corrective maintenance' to 'preventive maintenance' at the ordering party (city, ward, town, village, etc.) involved in your work, and name one major barrier preventing this transition.

3. Among the three 'bundles' (bundle of local governments, bundle of businesses, bundle of engineers), state which one is easiest to realize in your work region and why.

4. If comprehensive private outsourcing (PPP/PFI) were applied to the infrastructure you are in charge of, state the 'technical judgment ability' that must be maintained as the ordering party and the core of the judgment that must not be outsourced.

5. If resident-participatory maintenance (using apps like 'Bridge Log') were to be introduced in your work region, state the scope of daily inspections that residents can handle and the boundary line for judgments that should be handled by experts.

6. Regarding the facilities under your management, state whether you have a rough estimate of the cumulative 30-year cost, and if not, what data is required.

7. List the benefits (cost, technological innovation) and risks (policy changes during the contract period, dependence on technicians) of applying a long-term comprehensive contract, such as Water PPP, where 'even the creation of the original plan is entrusted to the private sector,' to the facilities you manage.

8. Describe the consensus-building process with heads of local governments and assemblies required to realize a 'bundle of technicians' (personnel exchanges between local governments, joint procurement, etc.) in your region, using actual examples or hypothetical scenarios.

9. Design the evaluation criteria (soundness, traffic volume, presence of alternative routes, etc.) for risk assessment and the rules for priority investment in high-risk facilities when applying Risk-Based Management (RBM) to your inspection plan.

10. Describe one specific situation in your work where 'economic management' and 'human resource management' were most in conflict, and state which you prioritized and how you managed the residual risk.

Chapter 8 Basin Flood Control (Social Environment × Safety)

8-1. Citation points from the original MLIT White Paper R7

The 2025 MLIT White Paper positions 'Basin Flood Control' as a core measure for national resilience to address intensifying water disasters, and calls for the construction of a multi-layered disaster prevention system that combines hardware development with green infrastructure and resident collaboration. The following five original data points can be used directly in your essay.

1. Basin Flood Control Related Laws (Amended/Enacted in 2021)

With the amendment of the Act on Countermeasures for Flood Damage in Specified Urban Rivers, measures against inland flooding in urban areas have been strengthened, and the formulation of flood control plans at the 'basin' level, involving local governments, private businesses, and residents, has been made mandatory. Basin-level plans include not only in-channel measures (levees, retarding basins) but also runoff suppression and flood control measures in upstream, midstream, and urban areas.

2. Paddy Field Dams

Utilizing the water retention function of farmland, rainwater is temporarily stored in paddy fields during rainfall to suppress flood runoff downstream. While construction costs are almost zero and it is immediately effective, the cooperation of farmers is essential, making consensus-building difficult. There is also a risk of damage to crops if the duration and depth of water stagnation are not managed.

3. Green Infrastructure (Eco-DRR)

A concept that exerts disaster prevention effects in parallel with hard infrastructure by actively maintaining and restoring the disaster prevention functions inherent in forests, wetlands, and coastal ecosystems. Eco-DRR (Ecosystem-based Disaster Risk Reduction) is consistent with the UN SDGs and the Sendai Framework for Disaster Risk Reduction 2015-2030, making it a useful point for discussion from the perspective of accountability to the international community.

4. Systematization of Disaster Prevention Meteorological Information (June 2024)

By unifying the names of meteorological information that had become complex, such as 'Emergency Heavy Rain Warnings, Sediment Disaster Alerts, and Flood Warnings,' into 'Alert Level Equivalent Information,' improvements were made to eliminate hesitation in residents' evacuation decisions. Clarifying information transmission functions as infrastructure for stakeholder consensus building (PI).

5. TEC-FORCE (Technical Emergency Control Force)

A system is in place where the Ministry of Land, Infrastructure, Transport and Tourism's TEC-FORCE is dispatched to disaster-stricken municipalities to support rapid damage assessment and the formulation of recovery plans. TEC-FORCE was also dispatched early during the Noto Peninsula Earthquake (January 2024) and took charge of prioritizing lifeline restoration. The R7 White Paper specifies the strengthening of TEC-FORCE's scope of activities and coordination systems as a system improvement following the Noto Peninsula Earthquake.

8-2. Details of 5 Management Trade-offs

Main Axis: Social Environment Management × Safety Management

For each issue, we will organize the requirements of both management types and the essence of the conflict.

• Levee Development vs. Green Infrastructure

  • Social Environment Management Requirement: Ecosystem conservation, landscape maintenance, and inheritance of local culture

  • Safety Management Requirement: Desire to maximize the certainty of flood protection

  • Essence of Conflict: Conservation of the natural environment vs. reliable protection levels

• Introduction of Paddy Dams

  • Social Environment Management Requirement: Maintenance of agricultural landscapes and ensuring agricultural productivity

  • Safety Management Requirement: Uncertainty regarding whether flood peak flow reduction effects can be reliably obtained

  • Essence of Conflict: Agricultural environment conservation vs. uncertainty of disaster prevention effects

• Designation of Retarding Basins

  • Social and Environmental Management Requirement: Restriction of Property Rights of Landowners through Land Use Regulations

  • Safety Management Requirement: Reliable Effectiveness as a Safety Valve during Large-scale Floods

  • Essence of Conflict: Socio-economic Interests of Landowners vs. Safety of the Entire Basin

• Green Infrastructure Development

  • Social and Environmental Management Requirement: Ecosystem Restoration, CO2 Absorption, and Landscape Improvement

  • Safety Management Requirement: Decline in Disaster Prevention Functions if Development and Maintenance are Delayed

  • Essence of Conflict: Environmental Symbiosis vs. Maintenance Costs and Reliability

Sub-axis 1: Safety Management × Economic Management

The development costs for hard infrastructure (levees, retarding basins, and detention ponds) are enormous, and prioritization is inevitable given the fiscal constraints of national, prefectural, and municipal governments. Setting the protection level (probability scale) of "how far to protect" is essentially an adjustment problem between economic management and safety management.

Sub-axis 2: Social and Environmental Management × Human Resource Management

Paddy dams and resident-led runoff suppression activities require a system where farmers, local residents, and municipal staff cooperate sustainably. The decline in agricultural workers due to the declining birthrate and aging population, along with the shortage of municipal staff, threatens the sustainability of green infrastructure and resident-participatory measures.

8-3. Tips for Thesis Development (M-A-P Model)

For theses on the theme of basin flood control, developing them using the M-A-P model (Mitigation hierarchy → All-hazard approach → Public involvement) creates a consistent logic for the arguments.

M: Prioritize measures using the Mitigation hierarchy

Apply the mitigation hierarchy, which considers environmental impacts in the order of "avoidance → reduction → substitution → compensation," to the planning of basin flood control measures. One can structure the arguments in the order of first "avoiding location and development in high flood risk areas" (land use regulation), then "reducing runoff and inundation depth" (green infrastructure, paddy dams), then "taking alternative routes and provisional protective measures," and finally "covering residual damage with compensatory measures (compensation, insurance)."

A: Respond to compound disasters with an All-hazard approach

After the Noto Peninsula Earthquake, the necessity of flood control plans that assume "compound disasters involving not only floods but also earthquakes, sediment disasters, and storm surges" has increased. The All-hazard approach is a concept of building a common disaster prevention foundation (evacuation plans, information dissemination, early restoration of lifelines) that can respond to all types of external forces, rather than specializing in specific disaster types. It functions as a table for integrated evaluation of social/environmental management and safety management.

P: Bring stakeholders together through Public Involvement (PI)

Basin flood control cannot be realized without the participation of diverse stakeholders, such as farmer consensus for paddy dams, landowner consensus for retarding basins, and resident participation in green infrastructure development. PI (Public Involvement) is a process of "transparently comparing multiple alternatives from the design stage in terms of cost, environment, landscape, and safety effects, and listening to and reflecting opinions." In a thesis, it is effective to develop the argument by "clarifying the causes of conflict (conflicts of interest) and reducing consensus costs through PI."

8-4. R08 Re-appearance Probability and Basis

Re-appearance probability: 8.5/10

• Social Incident: Following the Noto Peninsula Earthquake (January 2024), social attention to disaster prevention and mitigation is at its peak. R08 is the third-year exam since the earthquake, making it likely that policy evaluation will be questioned.

• Past Exam Record: Directly appeared in R05 Compulsory Subject I-2 ("Promotion of Basin-wide Flood Control") and R07 Compulsory Subject II-1 ("Utilization of Green Infrastructure").

• White Paper Frequency: "Basin-wide flood control" and "Green infrastructure" have been continuously featured in the R5, R6, and R7 editions.

• Related Legislation: The Basin-wide Flood Control Related Act (2021) and the Climate Change Adaptation Act Amendment (2023) have become established legal backgrounds that examinees should grasp.

• Clarity of Trade-offs: "Conservation of the natural environment vs. reliable flood protection" is a conflict structure for which graders can easily set evaluation criteria.

It has a high probability of reappearing, at the same level as i-Construction 2.0 (9.5) and infrastructure aging (8.5). In particular, questions regarding "complex disaster response" against the backdrop of the Noto Peninsula Earthquake are expected in R08.

8-5. Past Exam Application Passport

• R05 Compulsory Subject I-2 — "Issues and Measures in Promoting Basin-wide Flood Control": The entire M-A-P model can be applied directly.

• R06 Compulsory Subject I — "Disaster Prevention and Mitigation Utilizing Green Infrastructure": M (Mitigation hierarchy) and A (All-hazard) are the core.

• R07 Compulsory Subject II-1 — "Flood Control Measures and Consensus Building across the Entire Basin": The P (PI) phase (stakeholder consensus) is the core.

• R07 Compulsory Subject III — "Recovery and Reconstruction Management after the Noto Peninsula Earthquake": Respond with an All-hazard approach + TEC-FORCE coordination system.

Application Procedure (for 3-minute brainstorming)

1. Recall this chapter if the question includes any of the following: "basin, flood, green infrastructure, consensus building, complex disaster".

2. Use white paper figures (2021 Basin-wide Flood Control Act, rice paddy dams, 2024 unified weather information) as the basis.

3. Develop "prioritization of measures → complex disaster response → stakeholder consensus" in the flow of M-A-P.

8-6. Worksheet (Application to Own Work)

By answering the following 10 questions, you will complete an essay outline that applies the contents of this chapter to your own work. Please fill in the blanks with your own words.

1. Estimate the flood and inundation hazards with the highest risk in your work (or assigned area), and approximate the assumed inundation depth, inundation area, affected population, and assets.

2. List at least one green infrastructure measure (rice paddy dams, retarding basins, forest conservation, etc.) that is being (or should be) addressed in that area from the perspective of "basin-wide flood control".

3. Explain the stakeholders with whom it is most difficult to build consensus when introducing rice paddy dams or retarding basin designations in the area, and the structure of their conflicting interests.

4. Please indicate the current implementation phase when applying the mitigation hierarchy (avoidance → reduction → substitution → compensation) to the flood risk in the relevant region, as well as the next phase to be addressed and its specific measures.

7. Regarding rivers, reservoirs, and farmland related to your work, please confirm the status of the formulation of the basin flood control plan based on the Basin Flood Control Act (2021) and identify the roles that your company or organization should play within it.

8. If you were to design a management system (costs, personnel, frequency) in a sustainable manner for your region to maintain the disaster prevention functions of green infrastructure (algae beds, tidal flats, wetlands, etc.), please describe what kind of organization and funding scheme would be necessary.

9. Based on the unification of disaster prevention weather information alert levels (June 2024), please state whether there are any deficiencies in the means of transmitting evacuation information to residents in your assigned region (disaster prevention radio, SNS, apps, etc.), and describe specific measures if improvements are needed.

10. Please describe one specific decision-making scenario in your work where 'social environment management' and 'safety management' were most in trade-off, and state which one you prioritized and how you managed the residual risk.
