SC-102_Combination_Curb_And_Gutter_(2025).pdf

This is a City of Pittsburgh Standards of Construction technical drawing (DWG. NO. SC-102) detailing a Combination Curb and Gutter design specification for municipal infrastructure projects. The technical drawing provides precise engineering specifications for constructing curb and gutter infrastructure, including detailed measurements, materials, and construction requirements. The drawing specifies the use of Class "A" concrete, #4 steel bars at 18" O.C., a 1/2" expansion joint, polystyrene joint material, and a 4" diameter thermoplastic perforated pipe for underdrain connections.

The drawing includes technical specifications for aggregate materials (AASHTO No. 57 coarse aggregate), geotextile requirements for pipe and underdrain, and specific construction joint spacing and sealing guidelines. The design incorporates drainage considerations, with instructions for slope matching adjacent roadways and proper drainage implementation. The technical drawing is part of the City of Pittsburgh's standard infrastructure construction specifications, likely to be used in upcoming concrete, brick, and blockstone repair, replacement, and renovation projects within the municipal jurisdiction.
