Community Participation

School Design Advisory Team

Early in the design process, representatives from the school community come together to form a school’s SDAT. SDATs typically include school and district staff, parents, and community members. Students are sometimes included for all or part of the process. The project construction managers also take part. Learn more about Mercer International Middle School SDAT.

About the Project

The existing Asa Mercer Middle School building will be demolished and a new mass timber multi-story middle school building of approximately 174,000 sq. ft. constructed. Once complete, the new school building will provide permanent space for 1,000 students in grades 6–8.

The new one- to three-story school will be surrounded by landscaping and outdoor learning spaces. A synthetic turf practice field is planned for the east side of campus. A new, secure entry will welcome students, families, and the community with a clearly defined “front door” to the school.

Classrooms will be organized by academic neighborhoods, with flexible support spaces to promote a sense of community and support academic success for all students.

Sustainable design features are built in to meet district goals for clean energy and renewable resources.

Interim Location: During construction, Mercer International Middle School will be located at the Van Asselt School Interim Site, 7201 Beacon Ave. S. An addition is being constructed at that location to convert it to a site large enough for temporary use by middle schools.
