Agency Technical Reviews

The Cost Engineering Center of Expertise (MCX), at the Walla Walla District, is authorized by Headquarters to conduct peer review (ATR and External Peer Review [EPR]) of cost estimates, construction schedules, contingencies and escalation included in all decision documents.

Risk Analysis

Specific guidance and methods are established for Total Project Costs exceeding $40 million; however, this does not reduce the significance of the requirement for a risk-based analysis for projects under $40 million.

Headquarters has established an Abbreviated Risk Analysis process as an acceptable method in addressing the regulations for risk based analysis for Total Project Costs under $40 million.

Did You Know?

  • Along with providing support to all Corps districts, the MCX has provided cost support to locations such as Panama, Afghanistan, and, most recently, Brazil. The MCX has led multi-discipline teams comprised of 1 to 75 individuals working toward the same product delivery, including the largest construction projects in the United States (i.e., Waste Treatment Facility, $13B, Department of Energy, and Hurricane Storm Damage Risk Reduction System, $15B, USACE). Members of the MCX have testified before Congress as experts on cost-related matters. 
  • The construction equipment publication is used on all Corps construction projects and throughout many government agencies.  The publication originated in the Walla Walla District during large dam construction and has become the national basis for equipment estimation for heavy construction.   
  • The MCX provides training for Executive Staff, Project Managers, and the entire Project Delivery Team on the areas of cost development to help better understand issues and various factors that affect costs.
