Dardenne Tank Rehabilitation Project

The Dardenne Tank Rehabilitation Project, issued by the Las Virgenes Municipal Water District in Calabasas, California, involves the comprehensive restoration of the Dardenne Tank. The scope of work includes the total removal and replacement of interior and exterior coatings, pinhole and rafter repairs, and various site improvements such as replacing the perimeter fence and gate. Critical technical requirements include the installation of a submersible tank mixing system, roof hatch and vent replacements, and the installation of temporary water storage tanks of at least 93,000 gallons to maintain service during rehabilitation. All materials used inside the tank must be NSF-61 certified, and the completed structure must pass a 24-hour leak test and a formal disinfection process. The contract will be awarded to the lowest responsible bidder who meets specific qualifications, including QP-1/QP-2 certification or ten years of similar tank painting experience. Bidders must submit sealed proposals by October 23, 2026, and provide proof of DIR registration and a detailed subcontractor list. The successful contractor is required to furnish payment and performance bonds each equal to 100 percent of the contract price. Project administration will be managed via CIPO software, and the contractor must provide a dedicated project manager, superintendent, and field engineer. Work must adhere to California Building Code and OSHA standards, with working hours restricted by local HOA regulations. Final payment is structured as 95 percent of the actual work value, with the remaining balance released within 30 days of the recordation of a notice of completion.
