We are not creating drawings. We are creating a space for decision-making. ─ What Kukan Honyakusha will start doing from now on ─
Until now, at Kukan Honyakusha, we have written about:
* Point clouds do not exist for the sake ofBIMthemselves
* Information called "noise" also has meaning
* Point clouds can record changes over time
So, how do we apply that way of thinking to actual work? In this article, I will write about the work that Kukan Honyakusha will be taking on from now on.

There is information on-site. But it is not being used as material for decision-making.
In the construction and facility industry, various types of information exist.
* Point cloud data
* BIM models
* CAD drawings
* On-site photos
However, each is managed separately, and it is not uncommon for people to combine them in their heads to make decisions when necessary. It looks fine on the drawings. It looks like there is no interference on the BIM model. Even so, once construction begins, problems such as "it's narrower than I thought," "equipment is interfering with each other," or "the delivery route cannot be secured" can occur. It is not that the information did not exist. It is that the information was not being shared in a form that could be used for decision-making.

What Kukan Honyakusha does
At Kukan Honyakusha, we organize spatial information according to the purpose, based on the point cloud data, BIM data, and CAD drawings that are held. What is needed is not to model everything in detail. What is important is to make the information necessary for judgment visible. We integrate point clouds, BIM, and drawings, and organize things such as:
* Areas where interference is expected
* Delivery routes
* Clearances
* Differences between current conditions and design
* Points to be careful about
and summarize them as a report. The goal is not to create a beautiful 3D model. It is to prepare
materials that can be used for judgment
on-site.

You can share the same space even without a BIM environment
BIM is a very effective technology. However, it is not always the case that all stakeholders are in an environment where they can use BIM software. Even if a design company utilizes BIM, it does not mean that construction management, subcontractors, facility companies, and clients have the same environment. As a result, information that can be confirmed in 3D sometimes returns to explanations using 2D drawings or images. At Kukan Honyakusha, we organize integrated data into a format that can be viewed with the free Navisworks Freedom. Therefore, there is no need to introduce expensive BIM software. With just one laptop, stakeholders can confirm the same 3D space. We create a state where designers, construction managers, subcontractors, facility companies, and clients can discuss while looking at the same thing. What Kukan Honyakusha wants to provide is not software. It is
common decision-making material
.

There are problems that are too late to solve once construction begins
If problems are found after construction begins, it requires:
* Revision of drawings
* Review of the schedule
* Re-coordination with stakeholders
In some cases, rework occurs. And the impact becomes greater as the project progresses to later stages. When the construction period becomes tight due to design changes or adjustments, the burden may concentrate on the final stage. Work that originally required sufficient confirmation and adjustment must be carried out within a limited period. What Kukan Honyakusha aims for is not to solve problems solely through the efforts of the site. It is to increase the information that can be confirmed before construction begins and reduce unexpected problems. By doing so, we create a state where people working on-site can secure the time they originally need. That is also one of the major purposes of sharing space.

What Kukan Honyakusha wants to provide
The goal is not to integrate point clouds. The goal is not to create reports either. What stakeholders really need is not to deal with things after construction begins, but a state where they can make judgments before it begins. What Kukan Honyakusha wants to provide is that
decision-making material
. In marketing, there is a way of thinking that says,
"People do not seek a drill itself, but tools for the purpose of making a hole."
Kukan Honyakusha is the same. What stakeholders really need is not point clouds. Not BIM. Not Navisworks. What is needed is:
* Being able to grasp problems before construction
* Being able to talk with stakeholders on the same premise
* Being able to reduce rework
* Having the information necessary for judgment available

Conclusion
What Kukan Honyakusha aims for is not to create 3D data. It is not a job to deliver drawings. It is a job to
deliver decision-making materials. Instead of treating point clouds, BIM, and drawings as separate information, we organize them as
a single space that can be used for decision-making. By sharing that space, we create a state where design, construction, subcontractors, facility companies, and clients can discuss on the same premise. That is the work that Kukan Honyakusha will be taking on from now on. Currently, we are preparing this service for verification in practical work. I want to utilize point cloud data and BIM data more in practical work. I want to align the understanding of design and construction in a 3D space. I want to increase the information that can be confirmed before construction. If you have such issues, please contact us via the email address listed in the profile section.
Also, if you have any points that were difficult to understand while reading, or opinions such as "it seems usable in this situation in practice" or "it doesn't seem usable," I would appreciate it if you could provide them in the comments.
