Diagram_-_On-Grade_Concrete_Steps_-_All_Widths.pdf

The document is a technical engineering diagram for on-grade concrete steps, prepared for the City of Pittsburgh's Department of Mobility and Infrastructure as part of a Steps & Stairways Repair/Replace/Renovate contract opportunity. The detailed schematic provides precise dimensional specifications for concrete step construction, including a 12.00-inch width, 18.00-inch height, and various landing configurations. The diagram specifies technical details such as #4 and #5 coated rebar placement, 1/2-inch expansion joint material, and notes that landing dimensions will be finalized by a City representative.

The diagram includes an important notation that the dimensions and details are for illustrative purposes, acknowledging potential field condition variations. The document explicitly states that no adjustments will be made in the bid price, but reasonable adjustments may be determined by the City representative based on actual on-site conditions. The technical drawing provides a standardized design template for concrete step construction, with specific measurements for longitudinal and transverse rebar placement, step geometry, and expansion considerations to ensure structural integrity and consistency across potential construction projects.
