Construction_Drawings_-_Final_20221202_CitySigned.pdf

These construction drawings are for the City of Pittsburgh's Department of Mobility and Infrastructure, specifically detailing the replacement of the Frazier Street Stairs in the 4th Ward of South Oakland, Allegheny County, Pennsylvania. The project involves completely removing the existing stairs and constructing new stairs connecting Frazier Street and Bates Street, with a project number of 210076. The detailed drawings include comprehensive site plans, alignment details, stair segment profiles, earthwork details, sidewalk specifications, erosion and sediment control plans, and technical stair construction specifications. The design incorporates various technical elements such as cast-in-place landings, jumper stairs, elevated stair railings, concrete structures, drainage systems, and erosion control measures.

The drawings provide extensive technical specifications for construction, including detailed measurements, material requirements, and construction sequencing. The project includes multiple technical components such as 1 1/2" diameter welded pipe railings, cast-in-place concrete elements, subsurface drainage outlets, concrete/grout washout areas, and specific erosion control techniques. The design accounts for the existing topography, with careful consideration of ground elevations, utility lines, and surrounding infrastructure. The documents also include geotechnical information through test pit logs and visual classification logs, suggesting a comprehensive approach to understanding the site's geological conditions prior to construction. The project appears to be fully engineered and ready for bid, with precise technical specifications that would allow contractors to develop accurate construction proposals.
