DESIGN NOTES GENERAL NOTES CONSTRUCTI❑N NOTES Cross wires Skew an€ Designation: Standard single or multiple precast box culverts are shown on the plans as span times height with maximum cover over roof thus: 8' x 5' RCB with 10' or double 10' x 5' RCB with 20', followed by alternatives. Alternatives: Single cell: Standard dimensions of AASHTO Material Specification 'M259' or 'M273'. Multiple Cell: Constructed by placl'ng single cells adjacent to each other. Inlet and outlet ends of culvert will be rounded unless square ends are designated. Parapet will be shown unless designated in plans. Such designation may be different for inlet and outlet ends. Limitations: Where the overfill is less than 1 foot, precast RCB culverts are not to be used. Precast RCB culverts are not to be used in siphon or pressurized installations unless appropriate "watertight" jointing is provided. Special Reinforcement Coverage: Precast RCB culvert standard details are not to be used in a corrosive environment or where there is a severe abrasive flow condition or freeze -thaw locations. Special design: Required for culvert with different conditions, or loads or design bearing pressures greater than those given on these plans. Required for culverts where end details need higher skew angles or higher parapets or barrier sections. PRECAST RCB TERMINOLOGY Note: Inner and outer reinforcement to be exposed as required to tie to cast -in-place construction.

For correct skew direction see plans. Cutoff Walls: 4' Cutoff wells are to be provided at inlet and/or outlet unless channel is lined and unless otherwise shown. These walls are to be extended if scour conditions warrant. See Standard Plans D84, D85 and D86A.
