Construction Study—Collaborations Yield Big Dividends

A study by the National Institute of Standards and Technology’s Office of Applied Economics, shows that the past, present, and future collaborations between the NIST Building and Fire Research Laboratory and partners, including two private-sector organizations—the Construction Industry Institute and the new Fully Integrated and Automated Technologies Consortium—will accelerate the industry’s plans for commercial deployment of builder-relevant information age products by at least four years. NIST economists credit the partners’ work—particularly the contributions of BFRL—on key enabling technologies, standard communications protocols, and advanced measurement techniques for the expected advance in product and services marketplace readiness. The analysts estimate the product and service availability in 2005, rather than 2009, will represent a cost savings to industrial facility owners, managers, and contractors approaching $150 million. For a copy of NIST Interim Report 6501, Benefits and Costs of Research: A Case Study of Construction Systems Integration and Automation Technologies in Industrial Facilities, are available from the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402.
