This report, ""Construction Industry Research Prospectuses for the 21st Century"", presents the thirty-eight propsectuses developed by industry experts at an international research symposium hosted by the Civil Engineering Research Foundation (CERF) in Washington, D.C. in February 4-8, 1996. Construction industry experts representing over 25 countries developed an international collaborative agenda for the construction industry to advance innovation in support of sustainable development concepts. The prospectuses, or proposed collaborative projects, identify challenges facing the engineering and construction industry and the problems associated with implementing innovative technologies. The prospectuses also recommend solutions to these challenges and details the benefits of these solutions; identify proposed collaborative partners; and estimate the cost and schedule associated with implementing these projects.
