Approve the capital expenditure of $115,000 for Work Order No. 1420055, which includes all design, construction, change order contingency, construction management and inspection costs for the metal door assembly at the John W. North Water Treatment Plant Project — Bid No. RPU -7340. BACKGROUND: The chlorination room at the John W. North Water Treatment Plant consists of multiple bays where several chemicals are stored and injected into the treatment process of the plant. The chlorine bay is equipped with three chemical pumps, an array of several pipes, and a single 2,500 gallon tank, which stores the chlorine solution. Due to recent cracks in the tank, staff took the tank offline and provided a temporary tank elsewhere at the plant to continue to treat water. The cracked chlorine tank needs to be replaced. The components in the chlorine bay and chemical room are configured and mounted in a manner leaving limited space to remove the tank through the existing access. In order to replace the tank, staff prepared specifications to construct access directly to the chlorine bay. Staff proposes to construct a set of doors at the chlorine bay, remove portions of the walls, modify the concrete slab to accommodate a new chlorine tank, and retrofit the array of pipes. This project was advertised by staff on July 23, 2015 and bids were opened on August 19, 2015.
