Evaluating Alternative Methodologies for Capturing As-Built Building Information Models (BIM) For Existing Facilities

摘要

The operation and maintenance of U.S. Army real property could greatly benefit from the availability of advanced forms of digital as-built facility data, such as those used in Building Information Modeling (BIM) systems. The Army Corps of Engineers requires the use of BIM on all new construction projects associated with the Army Standardization program. However, new construction typically accounts for only a small proportion of an installation s real property assets. Current BIM technology is capable of capturing existing facility data, but developing models for all existing facilities is not feasible because of the cost. As an alternative to developing complete models for existing facilities, a subset of BIM data could be developed to capture the data needed to improve the cost-effectiveness of operating and maintaining existing facilities. The University of Washington was contracted by the U.S. Army Research and Development Center under the Installation Technology Transfer Program to perform a comparative analysis of different methodologies for capturing as-built BIM data for existing facilities at Fort Lewis, WA. This report provides the results of that analysis.
