Construction Review

Review of Construction Projects

The Office of Project Assessment (SC-1.3) within the Office of Science (SC) conducts independent technical, cost, schedule, and management peer reviews of SC construction projects and large experimental equipment. These reviews are known as “Lehman Reviews” after the Division Director, Dan Lehman. Lehman Reviews are widely known in DOE, other agencies, and abroad. Dan Lehman has briefed OMB and other agencies on the process, which has been adopted by other parts of DOE.

A primary responsibility for the Division is conducting reviews of major construction projects, which are typically held two times per year. The reviews may include 30-40 independent technical experts, who are divided into 6-8 subpanels during the review to investigate all aspects of the project. Reviews can result in modifications to the project, work stoppage, and management changes.
