Construction StudyCollaborations Yield Big Dividends
A study by the National Institute of Standards and Technologys 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 organizationsthe
Construction Industry Institute and the new Fully Integrated and
Automated Technologies Consortiumwill accelerate the industrys
plans for commercial deployment of builder-relevant information
age products by at least four years. NIST economists credit the
partners workparticularly the contributions of BFRLon 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,
