SC-502_Curb_Ramps.pdf

The provided document is a set of engineering design standards for curb ramps by the City of Pittsburgh's Standards of Construction. The technical drawings depict multiple types of curb ramps (Type 1, Type 2, Type 3, Type 4, and Type 100) with 6', 5', 4', and 3' sidewalk/landing configurations. Each design sheet includes detailed plan and section views, specifying precise measurements, materials, and construction requirements for handicap-accessible curb ramp installations.

Key technical specifications include using a concrete coating and sealer that is clear when cured, installing curbs separately from handicap ramps, and ensuring that ramps have specific slope limitations. The designs mandate that clear zones must be entirely within crosswalk lines and out of travel lanes, with detectable warning surfaces cast-in-place in federal yellow color. The standards also note that these designs are considered standard for ideal site conditions, with potential modifications contingent upon review and approval of a technical infeasibility form. The drawings provide comprehensive guidance for constructing compliant curb ramps that meet ADA solutions and municipal engineering standards.
