The latest rendering of the new Cunniff Elementary School, with the solar array in the parking lot. The bids on the construction projects at two of Watertown’s elementary schools came in millions of dollars below budget, but the requirements for working in the COVID-19 world will mean some added costs. Hosmer and Cunniff schools will start construction in June, and the bids were recently opened, said Town Council President Mark Sideris. The project budget estimated the cost of the two schools at just over $100 million including the cost of adding solar on the school roofs ($5 million), Sideris said. “The good news is low bidder came in at $92,335,000 and all the solar came in at $2.6 million,” Sideris said.
