Building next-generation BIM cloud-computing environment will increase customer satisfaction

TOKYO, August 26, 2011 — Obayashi Corporation announced that it has signed an
agreement on the joint development of a BIM cloud-computing platform with NEC
Corporation and GRAPHISOFT. The goal of the agreement is to provide technology
leadership for Obayashi through integrated building information modeling workflows
and company-wide BIM-based information sharing.

Obayashi has been working on reforming the use of BIM among the design, construction
and building operation functions within the entire company. With this alliance, and based on
GRAPHISOFT’s revolutionary BIM Server technology, Obayashi will achieve “seamless
information sharing,” which is the key advantage of BIM. NEC has been involved in many large
cloud applications and brings its know-how to the table, while GRAPHISOFT is the pioneer in
BIM software technology.

Obayashi is confident that by implementing the “Smart BIM Cloud” on a company-wide scale,
customers will benefit in a number of areas, including the ability to check the status during
design, construction, and completion of buildings, from anywhere and anytime on the web,
resulting in information on demand. This leads all stakeholders to a better understanding of
each phase beforehand, so that it will be possible to respond to customers’ requests in the
early stages, leading to consensus early in the design process. In addition, utilizing BIM will
result in the creation of a working environment in which each person involved in the building
process can cooperate quickly and seamlessly, greatly reducing the construction time. The
database contains not only geometric information, but also specification, supply, analytic data,
and everything that is necessary for construction. By using these in the production process,
construction time will be reduced and quality will be greatly improved.
