Diagram_-_Jumper_Walk_Steps.pdf

The document is a technical engineering diagram for Jumper Walk Steps, Type 3, developed for the City of Pittsburgh's infrastructure project involving steps and stairways repair, replacement, and renovation. The diagram provides detailed specifications for a standard jumper walk with steel handrailing, utilizing City Class P cement concrete with #57 course aggregate. The drawing illustrates the payment structure for steps, which is calculated by the width of the step installed and measured along the direction of travel, with sidewalk areas also being paid per square yard.

The technical specification notes that the jumper walk shown contains one step per unit, though the actual number of steps may vary based on field conditions and directions from the City representative. The diagram includes precise elevation details and payment demarcation lines in red, indicating how different components of the walk steps will be measured and compensated. The design appears to be part of a broader municipal infrastructure improvement initiative, with specific attention to standardized construction methods and clear payment guidelines for contractors bidding on the project.
