This document is a Critical Path Method (CPM) Schedule for the Stanton Ave/McCandless Ave Stairs Construction project, prepared for the City of Pittsburgh's Department of Mobility and Infrastructure (DOMI). The comprehensive project schedule spans from June 27, 2024, to May 12, 2025, detailing a multi-phase construction process involving pre-construction activities, site preparation, structural work, and project closeout. Key activities include developing quality control plans, obtaining necessary approvals, installing environmental and safety controls, drilling caissons, setting soldier piles, pouring concrete, installing precast panels and components, constructing landings, forming and pouring walls and foundations, and completing final site restoration tasks.

The schedule indicates a project duration of approximately 11 months, with specific milestones such as mobilization, pre-construction meetings, traffic control implementation, and phased construction activities across multiple landings. Critical path activities include caisson drilling, concrete pouring, curing periods, panel and component installation, and final site restoration. The project includes specific technical requirements like seeding and erosion control, with prescribed germination periods between March 15th and June 1st, and August 1st to October 15th. The final project deadline is set for August 25th, with the contractor required to complete all construction, restoration, and closeout activities by May 12, 2025.
