SA-200_Brick_and_Blockstone_Streets_and_Concrete_Margin_(2024).pdf

This document is a technical engineering drawing (DWG No. SA-200) from the City of Pittsburgh detailing standards for brick and blockstone street reconstruction and reinforced cement concrete margin construction. The drawing provides a comprehensive cross-sectional and plan view specification for street infrastructure renovation, including precise details for subbase preparation (8" depth), leveling bed composition (3/4" mix of sand and Portland cement), and roadway crown configuration with a typical 2% cross-slope. The technical specifications cover critical construction elements such as paver installation, concrete base reinforcement, and margin construction techniques.

The drawing includes specific technical notes regarding materials and construction methods, such as hand-butting brick pavers, using granulated slag or limestone fine aggregate, and reinforcement bar spacing (9" spacing for 24" margins). The document is designed as a standard construction specification for municipal infrastructure projects, providing detailed guidance for contractors on material selection, placement techniques, and structural requirements. While no specific contract value or bid details are present in the drawing, it serves as a technical standards document for street reconstruction projects within the City of Pittsburgh's infrastructure improvement initiatives.
