About this file
This document is a set of utility infrastructure design details prepared by the U.S. Army Corps of Engineers, Tulsa District, for the KC-46A Depot Maintenance Complex Support Infrastructure project at Tinker Air Force Base, Oklahoma City, Oklahoma.
The document provides technical specifications and installation requirements for multiple utility systems including water service connections, gas service lines, fire hydrants, post indicator valves, air release valves, and thrust blocks. Key specifications include: concrete pad requirements (8-inch minimum thickness by 24-inch square minimum in grass or asphalt areas with 3000 PSI concrete); fire hydrant placement minimum 5 feet away from structures and 3 to 7 feet from paved surfaces; low-profile hydrants (24 to 30 inches maximum) for locations within airfield security fencing; thrust block bearing area calculations based on 2500 PSF soil bearing capacity and 250 PSI pipe test pressure with a 1.5 safety factor; mechanical joint tapped caps for 8, 10, and 12-inch connections; and drainage requirements for dry barrel hydrants utilizing 7 cubic feet minimum of free-draining broken stone gravel. The specifications also require nonporous material separation (8 mils minimum visqueen or 15 lb minimum felt) between fittings and concrete blocks, joint restraint details submitted for approval, and coordination with the Contracting Officer regarding fire hydrant locking mechanisms and construction water usage. The as-built construction work guide (CWG) drawing is dated May 2016 under Contract No. W912BV-16-C-0029.
