Hornsby Bend Biosolids Management Plant Headworks Improvemen

The City of Austin is soliciting bids for the demolition of the existing Headworks facility at the Hornsby Bend Biosolids Management Plant and the construction of a replacement facility designed to significantly enhance operational capacity and safety. The project involves installing two multi-rake bar screens, odor control via a biotrickling filter, a new sludge receiving station with secondary containment, gravity belt thickener modifications, magnetic flow meters, air release valves, and dedicated electrical rooms housing MCCs, PLCs, transformers, and HMI workstations in the CoGen and FEB buildings. All work must comply with industry standards including ASTM, NEMA, NFPA, OSHA, and ANSI, and includes complete furnishing of labor, materials, equipment, and incidental items necessary for full system functionality. The contract is scoped as a lump sum or unit price arrangement under an IDIQ framework, with an estimated value of $745,000 derived from allowances for items such as soil contamination remediation, portable generator procurement, security hardware, and site access improvements. Bids must be submitted electronically through the Austin Finance Online portal by the deadline of July 30, 2026, with no amendments or modifications currently issued. Contractors are required to comply with stringent packaging, preservation, and labeling standards for materials, ensuring protection from environmental exposure during storage and transport, particularly for cementitious materials, coatings, and structural steel. Inspection and acceptance are the contractor's responsibility, with testing required throughout the process, including a minimum five-day Performance Acceptance Test. Key personnel including a Project Manager, Superintendent, and OSHA 30-certified Safety Representative must be designated and approved. Subcontractor participation goals are mandatory for MBE, WBE, MWB, and MWDB firms, with documentation of good faith efforts required if targets are not met. The contractor must submit comprehensive Operation and Maintenance manuals, warranty documents, spare parts lists, factory and field test reports, and an asbestos affidavit. While no formal FAR clauses apply, alternates are permitted with specific provisions requiring incidental items to be included with each. Evaluation is based on compliance with safety, MBE/WBE participation, labor standards, and technical acceptability, though no formal weighting or scoring system is defined. No UEI or CAGE code is required, and payments are expected through standard invoicing procedures without use of electronic systems like WAWF. The place of performance is the Hornsby Bend site, with all work and inspections conducted on-site.
