Pentagon Dry-Pipe System Replacement

Wright Patterson AFB, Dayton, OH
As part of a Design-Build team, Stanton Engineering provided fire protection support and consultation for the replacement of ten (10) separate dry-pipe sprinkler systems for the Pentagon WHS/FSD. We surveyed the existing facility and existing fire protection systems. We also provided a detailed fire protection design for the replacement dry-pipe systems. The fire protection design included drawings, specifications, water flow testing, basis of design, and hydraulic calculations. Our engineers provided extensive construction period support assistance to the general contractor, the project sprinkler installation contractors (2 each), and the Office of the Pentagon Fire Marshal’s Office (OPFM). We focused on expanding the OPFM’s capabilities so they would successfully accomplish the installation of ten (10) new code compliant sprinkler systems. Stanton Engineering was a professional fire protection engineer advisor and consultant to both HSU and the OPFM concerning system installation inspections and commissioning needs. Stanton Engineering provided shop drawings and calculation reviews, system materials submittal reviews, and review and responses to contractor and OPFM Requests for Information (RFI). Our engineers developed and submitted an approved Systems Operation and Maintenance Manual (SOMM) and as-built drawings for the project. We surveyed fire stopping penetrations, witnessed sprinkler systems acceptance testing and commissioning. Stanton Engineering also provided computerized hydraulics modeling and analysis, research studies for system compliance, and overall project construction close out in support of HSU and OPFM. This design/build project was undertaken as a result of system leakage in six dry pipe sprinkler systems due to microbiologically induced corrosion (MIC), exacerbated by the use of Schedule 10 piping and the lack of proper sloping of the branch lines and mains. |
