Computer-Integrated Building Processes

NIST researchers are developing rational techniques for defining and testing computer representations of information needed throughout the building process, from the conception of a building to its demolition. The goal of the program is to develop validated neutral data representations for use in standards for accessing, exchanging, and archiving information. As a corollary, the program seeks to develop testing methods that assure consistency, completeness, and correctness of information. The research draws on evolving information technologies, including knowledge engineering and semantic modeling. Subject areas for research include standards and codes, engineering drawings, and product data.

Past research has resulted in methodologies for representing, analyzing, and expressing standards, and for interfacing standards to computer-aided design systems. Recent results are being applied in the development and validation of national and international standards for product data. This work led to the improved 3D Piping IGES Application Protocol (AP) to meet a high-priority data exchange requirement of industry and government. It also has produced a prototype AP framework to provide a structure to classify APs and to plan DOD Computer-Aided Acquisition and Logistics Support Program APs and the work of the International Organization for Standardization's project on developing the Standard for the Exchange of Product Model Data.
