Excessive contract time is costly because it extends a construction crew’s exposure to traffic, prolongs the inconvenience to the public, and subjects motorists to less than desirable safety conditions for longer periods.
The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 298: Developing a Systematic Approach for Determining Construction Contract Timeseeks to provide a systematic approach for determining construction contract time for a wide spectrum of highway projects.
The document is supplemental to NCHRP Research Report 979:Systematic Approach for Determining Construction Contract Time: A Guidebook.
