Water Storage Tank Inspection, Cleaning and Repair Services

The City of Modesto is soliciting bids for water storage tank inspection, cleaning, and repair services under solicitation IFB-00070RB, with proposals due electronically by August 11, 2026. The work involves performing comprehensive inspections, sediment removal, corrosion evaluation, and repairs on 38 designated water storage tanks located across Modesto, utilizing underwater filming, chlorine neutralization with ascorbic acid, and adherence to AWWA D101-2024, ASTM, CAL OSHA, and ADCI Standard 11 guidelines. Deliverables include detailed digital inspection reports on USB drives with photographic documentation, corrosion analysis, and a stamped engineer’s report, all requiring final approval from the City’s Utilities Department representative. The contract award will be based on a trade-off evaluation considering price, quality of service, and performance, without predefined weighting or scoring criteria, allowing the city to select the proposal that best meets its needs rather than awarding solely to the lowest bidder. The contract has a base term of two years with three optional one-year extensions, potentially extending performance up to five years, with firm pricing guaranteed only for the initial two-year period. All work must be conducted during weekday hours from 6:00 AM to 2:30 PM to avoid disrupting water operations, using a three-person crew equipped with certified diving and inspection tools. Offerors must be in compliance with California prevailing wage laws, maintain a valid Modesto business license, and provide a DUNS number and federal taxpayer identification number, though UEI and CAGE codes are not required. Additional documentation including customer references, financial interest disclosures, subcontractor lists, and certification of experience is mandatory for submission via the OpenGov procurement portal, and failure to include any required form will result in disqualification. Payment will be processed either electronically through the ePay Mastercard system (Net 30) or by manual check (Net 45) to the City’s Accounts Payable office. The contract includes local clauses on termination, compliance with laws, contractor responsibility for damages, non-discrimination (including ADA), licensing, and records retention, but does not incorporate federal FAR clauses or specify packaging, shipping, or contracting officer representative details.
