Utility Penetration Sealing with Non-Combustible Materials

The contract requires the sealing of utility penetrations—including pipes, conduits, and cables—within pump stations using non-combustible fire-stopping materials to ensure the continued integrity of fire barriers. This work is critical for maintaining passive fire protection systems in accordance with life safety and building code requirements, particularly in high-risk infrastructure environments. The scope focuses exclusively on the application of fire-resistant compounds to prevent the spread of flames and smoke through penetrations in structural barriers, without altering or relocating the utility lines themselves. This subcontract is issued under NAICS code 238220 for Fire Protection and is managed by the Marin Municipal Water District in California. The solicitation was posted on July 15, 2026, and the work is to be performed at designated pump station locations within the district’s service area. Although specific site details and point of contact information are not provided, the contractual obligation centers on adherence to fire safety standards through precise, durable, and code-compliant sealing methods using only approved non-combustible materials.
