Construction is a capital acquisition subprogram composed of independent Line Item Construction projects that are created to address specific needs. These needs include replacement of aging facilities; incorporation of modern safety, security, and environmental protection standards; reconfiguration and consolidation to improve the efficiency of the nuclear weapon complex; and incorporation of new technology to provide infrastructure that is responsive to the future needs of the program. The capital portions of each line item project are independently reviewed and funded by Congress based on the mission need identified in the Construction Project Data Sheet (CPDS) submitted to Congress and the operating portion, which includes funding for oversight, are provided by the Operations of Facilities budget.
