About this file
This is an as-built construction drawing (CWG) for box culvert headwall and manbar details. The document is Sheet CU509 from the KC-46A Depot Maintenance Complex Support Infrastructure project at Tinker Air Force Base, Oklahoma City, Oklahoma. The contract number is W912BV-16-C-0029, administered by the U.S. Army Corps of Engineers Tulsa District.
The drawing provides detailed specifications for precast reinforced concrete box culvert sections with cast-in-place headwalls and manproofing components. Key requirements include: reinforcing steel with yield strength of 80 KSI; structural grade steel bars and angles galvanized with 2.0 ounces of zinc per square foot after fabrication; stainless steel bolts; removal of 12 inches of concrete from box culvert sections to expose reinforcement for headwall preparation; filling approximately 1-inch spaces between adjacent boxes with dry, fine sand; embedding Bars F and H into headwalls 8 inches; and installation of manproofing grates at each end of each box culvert. The drawing includes a table of variable dimensions specifying bar sizes, spacing, and quantities for various reinforcement components (Bars A through J). Manproofing of headwalls requires inspection and approval by the Contracting Officer. The drawing was prepared by Burns & McDonnell (Kansas City, Missouri) and dated May 2016.
