• The contractor must take measurements, analyze components, notate materials, and furnish labor and all materials to complete this project, which includes: o Supervision of Work o Preparation o Cleaning o Removal (grinding) of old welds and removal (cutting/scraping) of old caulking. Please specify any alternatives to grinding, cutting, or scraping. o Re-caulk the caulk line between Marcite and stainless steel Whitten top drain/gutter. o Re-weld or braze vertical seams and jets on stainless steel Whitten top drain/gutter. o Replace plastic/PVC hydrostatic valves with bronze hydrostatic valves and make water depth adjustment (currently pool water does not reach top drain/gutter, and water levels are not balanced due to non-functioning surge tank mechanical float valves). Pressure testing should be included prior to pool fill. o Replace surge tank mechanical float and valve (currently pool water does not reach top drain/gutter, and water levels are not balanced because a hydrostatic valves’ water level adjustment is needed). o Investigate side wall cracks and make repairs to the surface and/or subsurface with white Marcite. Please specify any alternatives to side wall crack re-plastering with Marcite to include filling or injecting. See Specs. • Adherence to site safety due to the risk of confined spaces, hazardous gases, water pressure, and mechanical hazards to include: o Confined Space Protocol Surge tanks are often classified as confined spaces, so follow local regulations (e.g., OSHA, HSE, etc.): Permit-required confined space entry procedures must be followed. Atmospheric testing for oxygen levels, toxic gases (e.g., hydrogen sulfide, methane), and flammable vapors. Use ventilation equipment to ensure safe air levels. Continuous monitoring with gas detectors is critical. Lockout/Tagout (LOTO) Ensure all valves, pumps, and electrical systems leading to or from the tank are locked out to prevent accidental activation. Communicate with control rooms or plant operators before and during work. o Fall Protection and Safe Entry Use tripods with retrieval systems or harnesses and lifelines for vertical entry. Ensure secure ladders or fixed access points are present. Have an attendant (hole watch) at all times when someone is in the tank. o Personal Protective Equipment (PPE) Helmet, gloves, safety boots Respirators if required based on air quality testing Chemical-resistant suits if working with or near hazardous substances o Water Pressure and Ingress Control Verify all water sources are isolated and tagged out. Be aware of potential for sudden water surges or pressure buildup in the system.
