The City of Austin is seeking subcontractors to perform comprehensive trenching, excavation, and backfilling services for water and wastewater pipeline replacement projects. This work includes excavating trenches, installing and maintaining trench support systems, removing spoil materials, compacting backfill, and restoring the site to its original condition or as required by local standards. The scope requires strict adherence to safety protocols, environmental regulations, and engineering specifications to ensure the integrity of underground utilities and public infrastructure. All activities must be completed with minimal disruption to surrounding areas and in compliance with municipal codes. The solicitation is open to qualified subcontractors with experience in utility-related earthwork and pipeline rehabilitation. Proposals are due by August 20, 2026, and the contract falls under NAICS code 237990 for other heavy and civil engineering construction. The work will take place within the City of Austin’s jurisdiction, and responders must demonstrate proven capability in managing complex site conditions, including urban environments with existing utilities and public access constraints. Bidders should be prepared to provide evidence of insurance, permitting compliance, and prior project success in similar municipal infrastructure efforts.
