General contractor McCarthy Building Companies recently celebrated the construction milestone of topping-out for Phase 2 of the multiphase construction and renovation project at Sunnyslope High School. Topping-out marks the placement of the final beam atop the newest three-story classroom building on the growing campus, which is located at 35 W. Dunlap Ave. in Phoenix. The Glendale Union High School District’s project at Sunnyslope High School allows the high-performing school to accommodate additional students. Phase 2 is slated for completion in fall 2023.

Phase 2 of the project, which began in May 2022, involved the demolition of several buildings and the construction of a new, three-story, 100,000-square-foot classroom building. Phase 2 will provide the campus with 40+ new classrooms, chemistry/biology labs, a library, art rooms and ELA rooms. In addition, the project team has completed renovations to the sports fields, including new turf on the football field, new bleachers, a resurfaced track, and renovated varsity baseball, varsity softball and JV softball fields on the campus.

“The excitement on campus over the past two years as students, faculty and staff have watched the campus transform and experience the new classrooms completed with phase 1 has been energizing,” said executive vice president Antonya Williams, who leads the education services team with McCarthy Building Companies. “Achieving the topping out of the newest building marks another major milestone for the Sunnyslope community and we’re proud to be able to celebrate with them as we move closer to the completion of this incredible project and prepare to welcome new students this fall.”      

Phase 1 of the campus construction project was completed in only seven months with McCarthy and its design partner Orcutt-Winslow providing design and construction services concurrently and the majority of the work occurring over the summer months. This strategy ensured completion of the initial phase by the beginning of the 2021/22 school year. Phase 1 included the addition of a three-story, 72,000-square-foot classroom building with 33 classrooms as well as space for band, choir, and the campus ROTC program.

The Glendale Union High School District is using school bond funds approved in the 2020 election by voters to renovate the campus, which first opened in 1953.
