The newly renovated and expanded high school will open to students when the 2013-2014 school year begins on Wednesday. The $71 million building overhaul is now substantially complete, with only “punch list” items remaining to be addressed. “For us, the opening day of the school season with the new high school is a very big deal,” said Town Manager Wayne P. Marquis. “We’re excited.” Marquis said a formal dedication ceremony will be held in October. The two-phase project, which broke ground in November 2010, is on time and is expected to come in under budget, Marquis said. The first phase included the renovation and expansion of the auditorium, the renovation of the academic wing and the field house, construction of the new three-story science wing, and the demolition of the old Dunn Wing, which had been serving as swing space during construction. The second phase involved construction of a new section of the building that will house the cafeteria, a new main entranceway, and offices for the guidance and special education staff, along with school and central district administration employees.
