Sequioa Union School District Electrical Upgrade

CEI served as the prime contractor for critical electrical infrastructure upgrades supporting new HVAC systems across four high schools: Woodside High School, Carlmont High School, Menlo-Atherton High School and Sequoia High School. The project included electrical upgrades across multiple campus wings to support new furnaces, heat pumps and condensing units serving classrooms, rooftops and exterior areas.

CEI upgraded electrical single-line systems and provided power for more than 175 HVAC units, installing 30- to 60-amp fused disconnects at each location. To accommodate increased electrical demand, the team installed major distribution upgrades, including new 800- to 1,200-amp switchboards, distribution boards, 500 kVA medium-voltage transformers and more than a dozen electrical panels ranging from 100 to 800 amps.

The project required simultaneous execution across four active school campuses while classes remained in session. Coordinating large-scale shutdowns was particularly complex due to limited work windows between the end of the school year, summer school sessions and the start of the academic year. Despite supply chain challenges and long lead times for switchgear, CEI successfully executed the work within a tight schedule and remained ahead of schedule throughout construction.

CEI’s Prefab division played a key role by fabricating all racking and supports for electrical pads, including above-grade and underground stub-ups. As a Division of the State Architect-regulated project, CEI maintained detailed documentation to ensure all work met specifications and received approval prior to installation. The project was scheduled for completion in September 2026.
