WWYK240015 - Rehab Tanks 62501E & 62501W

Questions & Answers / Clarifications

This document contains questions submitted by potential bidders and the government's responses regarding the "WWYK240015 - RFI RESPONSES" opportunity. It clarifies various aspects of the project, including technical requirements, materials, procedures, and responsibilities.

• New ICCP System: The contractor is required to design and install a new Impressed Current Cathodic Protection (ICCP) system, not just repair existing components.
• Draining and Cleaning: The government will be responsible for draining and cleaning the tanks at the contractor's request.
• Interior/Exterior Coatings: Specific coating systems (AWWA D102-21 ICS-2 interior, SW 7520 exterior) are referenced, with new applications acceptable for SW 7520. Products greater than or equal to specified standards can be submitted for approval.
• Containment and Blasting: Class 3 containment is required for blasting. Full enclosure with negative pressure/HEPA filtration is not required for exterior blasting. All blasting debris is considered hazardous waste.
• Design Responsibility: The contractor is responsible for completing any design elements required for construction, which will be handled through submittals and shop drawings, requiring government review and a professional engineer's stamp.
• Warranty Periods: A 3-year warranty for repairs/defects on work and coating, and a minimum 5-year manufacturer warranty are specified for interior and exterior coatings. The cathodic protection system has a one-year warranty.
• Outage Duration: The government anticipates approximately 2-4 months per tank for the complete scope of work, but the timeline is driven by contractor capabilities.

This Q&A document provides critical clarifications that bidders must consider when preparing their proposals. It details specific requirements for materials, design, safety, and project execution, directly impacting the scope of work and potential costs.
