BEST PRACTICE:

E1−4: Constructability Reviews by Construction Industry Representatives During Project Design

DESCRIPTION:

Working with the Colorado Contractor's Association, a construction contractor is selected to review and critique plans under development at about 30 percent complete stage. The constructability review should occur shortly after the Field Inspection Review stage of design.

REASON(S) FOR ADOPTING:

A constructability review should be conducted by the Region to define risks and potential costs associated with the project, and to eliminate problems with plans that could have been identified by those more familiar with construction or work phasing. Review by contractors allows correction prior to advertisement and start of construction.

PRIMARY BENEFIT(S):

Fewer costly changes during construction. Some savings in delay and congestion due to revisions to work sequencing or traffic control that affects users.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Constructability reviews are recommended for all "Signature Projects." A Signature Project is one that has a complex feature that is unique or different from most Colorado Department of Transportation (CDOT) projects. The complex feature requires extra consideration by CDOT when estimating the project and by bidders when bidding the project. Aspects to consider in determining the designation include, design features, constructability, and innovative delivery methods. The size of a project should not be a factor in its designation as a signature project.
