Installation of Styrene-Butadiene-Styrene (SBS) Modified Bitumen Roofing System

The New York City Department of Design and Construction (DDC) is creating a pre‑qualified list of contractors capable of installing Styrene‑Butadiene‑Styrene (SBS) modified‑bitumen roofing systems (e.g., Siplast P2030, GAF SBS Ruberoid Heat Weld, or approved equivalents) for a range of capital construction projects throughout the city. Qualified firms will be eligible for multiple roof‑installation contracts whose individual construction costs are expected to fall between $100,000 and $10,000,000. This solicitation is a Request for Qualifications (RFQ) to identify firms with the necessary labor, materials, equipment, and experience to perform these roofing installations. • Scope: Provide all labor, materials, equipment, and expertise to install SBS‑modified‑bitumen roofing systems on municipal buildings. • Qualification: Demonstrate experience with similar roofing systems, safety compliance, and capacity to handle projects ranging from $100 K to $10 M. • Outcome: Selected firms will be added to a pre‑qualified vendor list for future DDC roofing contracts.
