See <br /> 140 Ib/CF vert, 140 lb/CF horiz Multiple Cell: Standard Plans D84, D85 and D86A. <br /> Unit Stresses: Constructed by placing single cells adjacent to each other. Inlet Earthwork: <br /> f'c = 5.0 KSI and outlet ends of culvert will be rounded unless square ends are " ­Nog1"­­­?A <br /> designated. Parapet will be shown unless designated in plans. Such See Precast RCB Culvert, Excavation and Backfill Details sheet. <br /> fy = 65.0 KSI for welded wire fabric designation may be different for inlet and outlet ends. Construction Loads: <br /> n = 7 <br /> Limitations: Strutting may be required near temporary ends.
