Written by GovTribe AI · Jun 27, 2025

The document is a Critical Path Method (CPM) Schedule for the Stanton Ave/McCandless Ave Stairs project by the City of Pittsburgh's Department of Mobility and Infrastructure (DOMI). The comprehensive project schedule spans from August 1, 2022, to August 25, 2023, and details a multi-phase construction process involving pre-construction activities, site preparation, structural work, and project closeout. Key phases include concrete quality control planning, environmental and safety controls, caisson drilling, soldier pile installation, precast panel placement, foundation and landing construction, railing installation, and final site restoration.

The schedule indicates a structured workflow with multiple concurrent and sequential activities, including shop drawing submissions, reviews, fabrication, and construction stages. Critical milestones include anticipated Notice to Proceed on August 1, 2022, with specific deadlines for various technical reviews, material preparations, and construction elements. The project encompasses activities such as removing existing guiderails, clearing and grubbing, demolishing existing stairs, implementing traffic control, drilling caissons, pouring concrete, setting precast components, and completing seeding and erosion control measures. The final project deadline is set for August 25, 2023, with a comprehensive closeout process including final inspection, punch list item resolution, and complete site restoration.
