The ceiling assemblies at this Beaverton high school used multiple materials, making them a challenge to install.

Mountainside High School

Location: Beaverton

Contractor: Western Partitions

Architect: Bora Architects

Team: Armstrong World Industries, CWallA, Georgia-Pacific, GTS Interior Supply, Hamilton Drywall Products, Hilti, Knez Building Materials Co., Scafco Steel Stud Co., Spears Construction Supply

The $162 million Mountainside High School project in Beaverton involved the construction of over 340,000 square feet of finished space. Builders faced varied scopes and an aggressive schedule.

The finished spaces brought in natural light through the use of skylights, over 650 exterior windows, storefront entries and corridor relites. But the natural light placed extra demands on the quality of drywall finishes and levelness of acoustical ceiling systems to avoid shadowing.

The slab-on metal deck elevation variations, diversity of spaces, unique architectural features and use of multiple materials in the ceiling assemblies created significant challenges for installing the acoustical ceiling systems.

The common areas, bathed in natural and artificial light, were the architect's ceiling showpieces. The classroom entries required special attention since the door-frame relites, soffits and ceilings had to integrate perfectly.

The auditorium presented an acoustic challenge with a series of clouds suspended from the catwalks to perform as acoustical deflectors.

The band room ceiling system demanded precise building and placement of acoustical components for maximum performance. The lecture room, with its sloped seating and GypSorb drywall panel ceiling, and the media center forced Western Partitions into some creative problem-solving, a point of pride for their tapers.

In the science classrooms the pipe racks penetrating the plane of the ceiling demanded precise layout, cutting and ceiling tile placement.

With this project, Western Partitions overcame an unforgiving schedule, trade partner coordination issues, multiple acoustical-ceiling systems integrations, and design team expectations.

Judge’s comment: “The wide variety of ceiling products made this a technical challenge to implement. And, indeed, the contractor overcame the many challenges to provide a beautiful outcome.”
