As part of the Entiat Schools project, the company will be responsible for improving facility comfort.
The building energy use of a combined high school and middle school will be reduced by replacing ageing packaged rooftop units with new variable refrigerant flow and dedicated outdoor air systems.
Willdan will redesign and replace the roofing and windows while the facilities will also receive an upgrade to the building automation system.
The enhancements will ensure easy, accurate temperature control in the classrooms and multipurpose facilities, reducing annual operating and maintenance costs.
Entiat Schools superintendent Miles Caples said: “Their assistance with public communications helped us to pass a $6m bond for our upgrade projects.
“Willdan’s guaranteed construction cost and guaranteed savings has given us peace of mind that we can achieve more comfortable, energy-efficient classrooms with minimal risk on our end.”
Meanwhile, Willdan will collaborate with Vancouver Public Schools to carry out a full heating, ventilation and air conditioning (HVAC) system redesign and upgrade, single pane window replacement, and lead abatement at Hough Elementary.
Under this project, the company will replace a boiler plant with high efficiency options and controls upgrades at two other elementary schools.
The proposed upgrades are set to minimise the schools’ maintenance costs, improve air quality and eliminate exposure to environmental toxins, while also saving energy.
Project work is expected to be completed by the end of this year.
Willdan Group CEO and chairman Tom Brisbin said: “These projects mark an expansion in our relationships with K-12 schools in Washington.
“We’re pleased to continue growing our geographic footprint in the Pacific Northwest as more school districts see the advantage in Willdan’s turnkey approach and become long-term partners.”
