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, machine- interpretable 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. Because design and construction operations in the general buildings industry are carried out by project teams comprising multiple organizations, data interoperability across a heterogeneous software landscape is necessary. In order for that interoperability to be achieved, the domain experts in the general buildings industry must reach a consensus on key information-supported work processes and the information required by those processes.
