Abstract:
The 2004 Construction Users Roundtable (CURT) report,
Collaboration, Integrated Information and the Project
Life Cycle in Building Design, Construction and
Operation (WP-1202), makes clear that there is a
compelling need to improve project delivery. "Building
owners, particularly those represented within CURT,
regularly experience project schedule and cost
overruns." The National Institute of Standards and
Technology (NIST) study Cost Analysis of Inadequate
Interoperability in the U.S. Capital Facilities Industry
(NIST GCR 04-867) makes clear that all stakeholders in
the capital facilities industry - designers,
contractors, product suppliers and owners - are wasting
a huge amount of money looking for, validating and/or
recreating facility information that should be readily
available. For example, the study estimated that
operations and maintenance personnel spent US $4.8
billion during 2002, verifying that documentation
accurately represented existing conditions, and another
US $613 million transferring that information into a
useful format.These are two major business drivers that
are leading the general buildings industry to adopt a
more advanced technological approach to designing,
documenting and constructing capital facilities. It is
clear from the case studies assembled for this guide and
from the input of the General Buildings Advisory Panel
that these advanced technologies are yielding the
desired results. So far, major successes have been
recorded using highly accurate and complete 3D building
models for interference checking and linking to
construction schedules. These successes can be
attributed to the relative maturity of 3D modeling and
viewing technology as well as the availability of tools
for accurately translating geometry between proprietary
formats and for merging 3D models created in multiple
formats in an integration environment. Some progress has
also been made in the area of intelligent building
modeling, which captures the properties of building
components as well as their geometry, permitting direct,
machineinterpretable input to other applications, such
as analysis programs. A major success in this regard has
been the American Institute of Steel Construction's
(AISC) CIMSteel Integration Standards/Version 2 (CIS/2)
initiative, which has proven to enhance the quality and
speed of information flow throughout the steel supply
chain.
