Accelerated Bridge Construction Documents

Please note, CDOT has recently moved its Headquarters and Region 1 HQ to: 2829 W. Howard Place, Denver, CO 80204. Please update this address change in all documents that still have the old CDOT address (4201 E. Arkansas Ave. Denver, CO 80224) in them, thank you. In the past, the Department used an Accelerated Bridge Construction (ABC) Decision Chart during project scoping to determine if ABC was appropriate for the site. This chart was based on the Federal Highway Administration Manual entitled “Decision-Making Framework for Prefabricated Bridge Elements and Systems (PBES), May 2006”. This process was based on a set of questions regarding specific constraints of each project. If certain thresholds were met, ABC was recommended.
