|"We want to innovate the design work for the land development such
as the construction of golf courses or housing areas by CIM(Construction
Information Modeling) technology".
Taking golf course improvement as opportunity, the company got an idea to recreate and show how land form in the course will change and how landscapes will be seen by user's eyes from the beginning of designing with 3DVR. The company has been developing "3-dimensional design and development support system" for land reclamation project, which is based on a 3D real-time VR "UC-win / Road", and it has completed after 2 years (2013-2014) development cooperated with FORUM8. Mr. Hirai, the technical manager of the company's technology and production division, expects to take advantage of in various fields of development resultstakes by taking a look back at the progression and implicating evolvement.
Our user to introduce in this issue engages in the civil engineering of a wide range of projects, Takenaka Civil Engineering & Construction Co., Ltd. We focus on the technical department, located in the technology and production division to support the company's instructure, in charge of various correspondence to company-wide technical issues.
The company has almost all lisences of FORUM8 products. Especially, our program "Design Calculation of 3D Steelpipe Sheetpile Foundation" which supports to design Steelpipe Sheetpile Foundation was produced based on the company's contract development services. In that vein, they introduced UC-win Road since the early stage. They put it into practice and equips various functions required in land reclamation projects described above, and it has led to the joint development of new systems that can express the construction results reflecting the differences in design effectively and efficiently in 3D · VR.
Takenaka Group consists of companies involved in architecture,
construction and civil engineering(8 Construction
Business companies and 6 Management Engineering Business
companies) and uses Takenaka Corporation, originates from shrines and temples concrete business of the early Edo period, as its hard core. Takenaka Civil Engineering & Construction Co., Ltd. have one of the most history in this construction
business in Japan and is widely responsible for the civil engineering
▲The flow of 3-dimensional design and development support system based on UC-win/Road
In the sense that the company-wide issues related to technology, CIM is one of the biggest business that Mr. Hirai has to tackle now.
Receiving this idea of desire to show in the design phase of the land reclamation project how landforms and landscape will be after renovation in visual, development of "3-dimensional design and development support system" based on "UC-win / Road" started in fiscal 2013.
It is made an arrangement that users can check the change in the landforms corresponding to the change of the 3D data from different angles while they move the ground freely like a clay on 3D-VR, and that users can reproduce golf course-specific landscape quite realistically.
Also, in addition to display subtle gradient like green superimposed on the VR, it corresponds that presentation of while changing the landform, and CAD by feedback of changed landform. It is able to show the change of the landscape accurately and instantly during the meeting at the clients.
While the technology and design division in the Tokyo head office, which had the golf course renovation that became the beginning of the system development, played a central role in the first year, the technology and design division in the Osaka office joined in fiscal 2014, which had similar visualization needs in housing land development. They made efforts for the function enhancement such as responding to any shape input of the gradient shape, improvement of landform processing, golf course construction-related and soil amount calculation.
Especially, the surface function has been added in order to put the wireframe when terrain elevation is changed. It selects an arbitrary curve during terrain selection and automatically complements a mesh. And it is possible that textures can be changed on aerial photograph by height during the changing of terrain elevation to comprehend it easily in visual, and it is also possible to calculate soil amount calculation of elevation change places.
"At first, I imaged (mainly) the operation on a tablet". A variety of awareness in the process of system development are reflected. For example, while from the use scene of entering simply by touching or showing, tablets are considered more practicable, it became apparent that it is easier to use mouse in fact. Mr. Hirai says "I think that we achieved to make it better than we have thought we could".
As described above, we introduced UC-win / Road from early on. As the case which puts importance on the landscape such as land reclamation projects in historic buildings increases, the characteristics of UC-win / Road which is realistic 3D-VR and can reproduce movement of human or wind have been highly regarded in-house, says Mr. Hirai.
On the other hand, in the disaster site for example, it is needed to make object under the situation of no drawings situation in certain period, safely so that not to cause a secondary disaster. So it is expected in the future, that we survey from the sky by using drone (unmanned aircraft) and send the surveying data to design person of automatic operating construction machinery and offices in real time and reflect in the construction work immediately. He mentions that UC-win/Road will become the interface between people and equipment in such a scene.
Through this system development, the company realized certain functions which the company aimed. He remarks that from now on they aim to spread the application examples of the same system and to connect to appeal to the orderer the use merit.
