New Intake Tunnel Delivers Cooling Water to the Pentagon
The Pentagon needs to replace the existing intake and outfall lines for its Heating and Refrigeration Plant (H&RP). The plant services all of the heating and refrigeration capacity for the Pentagon, the Navy Annex and several other structures in the area. The intake and outfall lines are over 60 years old. The new lines will increase the water flow capacity both to and from the plant. Modern Continental is serving as the design/builder and Jacobs Civil is providing design and construction services as part of the Pentagon Renovation Program. The project includes the construction of a 2.3m (90-inch) diameter intake tunnel to deliver water to the H&RP chillers. Water will be drawn off the bottom of a nearby lagoon, which is cooler than the surface water. A 1.5m (60-inch) diameter condenser outfall pipeline will be constructed to discharge water into a waterfowl sanctuary. The project included several challenges including tunneling in a complex soft geology beneath the water table and crossing beneath a number of transportation systems. A design/build process with an integrated project team was selected to fast track the construction process. This approach has provided quick resolution of issues, an expedited review of design documents and real-time decision-making on proposed construction changes. A cost reimbursable contract with an award fee structure was used to share risk between the owner and design/builder. There is also an incentive program to help reduce the overall construction costs.
