North American Industrial Classification System code is 237110 - Water and Sewer Line and Related Structures Construction. Phase I will be conducted in accordance with FAR Subpart 36.3 and design-build selection procedures authorized by 10 U.S.C. 3241. Phase II will be conducted in accordance with the procedures authorized by 10 U.S.C. 3241 and FAR Subpart 15.3 and PGI DFARS 215.3.

New fire hydrants will be installed along the proposed alignments in accordance with the UFC and NFPA requirements, providing water main connections onto existing distribution mains and service lines that feed the current facilities, and providing new pressure reducing valve systems to balance the water distribution network?s pressure and flows. Proposed repairs to lines running through the runways include trenching the existing mains (abandon in place) and filling with flowable structural concrete, then backfill to existing grade with excavated material.
