Reese Street Caisson Treatment

The City of Pittsburgh's Department of Mobility & Infrastructure is soliciting bids for the Reese Street Caisson Treatment project, a critical landslide mitigation and infrastructure stabilization initiative located on the northern slope of Mount Washington near 107 Reese Street. The procurement, identified as Invitation for Bid #2023-IFB-219, seeks construction services involving limited mine grouting, installation of reinforced concrete caisson slope treatment, and limited rock scaling to address geological instability. Key project deliverables include designing and implementing a traffic control plan, construction surveying, erosion and sediment control, selective tree removal, site preparation, caisson installation, slope regrading, and site restoration. The project involves comprehensive technical specifications, including precise caisson treatment with perforated thermoplastic pipes, aggregate filling, and specific reinforcement requirements. The bid was released on August 30, 2023, with a pre-bid meeting scheduled for September 26, 2023, and bid responses due by October 10, 2023, at 2:00 pm. The project has a substantial completion timeline of 186 calendar days from the Notice to Proceed, with work restricted to Monday through Saturday, 7 a.m. to 8 p.m.

The contract appears to have no specific set-aside designations for disadvantaged enterprises, though it will be funded through the City of Pittsburgh and is subject to federal funding requirements, including Davis-Bacon wage rates and equal opportunity regulations. Bidders must provide a 5% bid bond and will be required to obtain performance and payment bonds for 100% of the contract amount. Insurance requirements include general liability, automotive liability, umbrella liability, and workers' compensation coverage. The project's estimated budget is not explicitly stated, but the detailed pricing proposal includes 31 line items covering various construction activities. Contractors will need to demonstrate expertise in geotechnical engineering, slope stabilization, mine grouting, caisson installation, and ecological restoration, with specific attention to working in complex geological conditions involving abandoned underground coal mines. The prevailing wage rates for the project have been determined by the Commonwealth of Pennsylvania's Bureau of Labor Law Compliance, with wage scales varying by trade and scheduled to increase incrementally over time.
