The Issaquah High School project consisted of three distinct construction phases resulting in a new high school of 285,000 square feet. The first phase, which included three academic wings, a central commons and cafeteria area, and three gymnasiums, was completed in just under 16 months. The second phase was highlighted by a 600-seat theater, black box theater, production studio, and CTE (career and technical education) facilities. During the final summer, Cornerstone demolished the remainder of the old campus to complete significant site and right-of-way work including a new 400-stall parking lot that was turned over prior to the upcoming school year. All phases were built in the middle of an operating campus, which required extensive planning to create protective barriers between construction and foot traffic.
“It’s not a common experience in the industry these days to work with such a proactive, forward thinking contractor as Cornerstone. On this fast-tracked, multi-phased project, you have not only succeeded in completing the phases with the tight project schedule, but have managed to do so with a great attitude, and a collaborative approach.”
