The FHWA Every Day Counts Program brought national visibility to implementing alternative technical concepts (ATCs) for incorporation in transportation projects. FHWA continues to encourage state DOTs to implement this alternative contracting method on projects delivered using design-build (DB), construction manager at-risk (CMR) or construction manager/general contractor (CMGC), and design-bid-build (DBB) contracts. ATCs have a well-documented potential for accruing sizable benefits in cost savings, increased constructability, and schedule reduction. In almost every case, the approved ATC was in reality a previously unrecognized approach to alter the design and enhance its constructability by matching the design of a given feature of work with the proposing contractor’s preferred means and methods.


The objective of this research was to develop a decision-making framework to assist transportation agencies in evaluating savings (cost, time, or both) from using constructability reviews and industry input during planning, design, and permitting. The framework was designed to be scalable to all contract delivery methods and comply with all statutory requirements necessary to mitigate impacts to the natural and cultural environment.




The Framework Toolkit will be available on the TRB Blurb Page along with the User's Guide once the official publication is released.
