SC-103_Mountable_Combination_Curb_And_Gutter_(2025).pdf

This document is a technical construction drawing (DWG NO. SC-103) from the City of Pittsburgh's Standards of Construction, specifically detailing a Mountable Combination Curb and Gutter design. The drawing provides a comprehensive cross-sectional view and specifications for constructing a standard curb and gutter infrastructure element, including detailed measurements, materials, and installation requirements. Key technical specifications include using Class AA concrete, #4 steel reinforcement bars, 4" thermoplastic perforated pipe with geotextile wrapping, and a 1/2" expansion joint with polystyrene joint material.

The technical drawing includes several critical construction notes, such as spacing construction joints at a maximum of 10'-0", using longitudinal reinforcement at specified dimensions, and specifying aggregate and concrete classes according to Penndot Publication 408, Section 704. The design incorporates specific materials like No. 57 coarse aggregate for the underdrain, a mountable combination curb and gutter configuration, and precise geometric specifications for drainage and structural integrity. The drawing is intended to provide a standardized template for infrastructure construction within the City of Pittsburgh, ensuring consistent quality and performance of street and drainage infrastructure.
