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.

This pamphlet establishes predetermined construction equipment ownership and operating expense rates for contractor-owned construction equipment.  It explains the methodology for developing the predetermined rates, provides a method for calculating rates for equipment where a predetermined rate has not been provided and a methodology for calculating dredge plant and marine equipment costs.  The overall intent is to develop equipment costs that are fair and reasonable.  A Microsoft Excel® workbook, named "CHECKRATE," is available for calculating equipment rates using the methodology and factors from Engineer Pamphlet (EP) 1110-1-8.

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.
