Riverview avenue landslide remediation - slide S1 & slide S3

The City of Pittsburgh's Office of Management and Budget, on behalf of the Department of Mobility and Infrastructure, is seeking qualified vendors to perform landslide remediation work along Riverview Avenue in the city's 26th Ward. The project involves constructing geosynthetic reinforced soil (GRS) slope fills at two specific sites: Slide S1 (a 150-foot long slope fill with a maximum height of 6 feet) and Slide S3 (a 234-foot long slope fill with a maximum height of 8 feet). Key deliverables include excavation, removal of slide debris, installation of geogrid fabric reinforcement, drainage improvements, asphalt restoration, guiderail installation, and site erosion protection. The bid (Invitation for Bid #2025-IFB-052) was released on March 17, 2025, with a pre-bid meeting scheduled for March 31, 2025, and responses due on April 14, 2025, at 2:00 pm. The project requires vendors with expertise in slope stabilization and geosynthetic reinforcement, with an anticipated Notice to Proceed on June 2, 2025, and a required final completion date of November 7, 2025.

The procurement emphasizes Disadvantaged Business Enterprise (DBE) participation, with specific participation goals and requirements for vendors to submit various documentation including a vendor questionnaire, Equal Opportunity Review Commission forms, and authorized signatory information. The project will comply with prevailing wage rates for work orders totaling $25,000 or more, with wage rates detailed in the attached Pennsylvania Department of Labor & Industry document. While no specific incumbent vendors are mentioned, the project includes 31 line items covering construction activities such as clearing and grubbing, excavation, geotextile installation, asphalt work, and geosynthetic reinforced soil slope fills. The total project area spans approximately 0.44 acres across two slide locations, with construction quantities including up to 775 cubic yards of selected borrow excavation and 3,280 square yards of secondary geotextile reinforcement. Though a specific budget is not explicitly stated, the comprehensive nature of the project and detailed technical specifications suggest a significant infrastructure investment by the City of Pittsburgh.
