Serco Inc in Chula Vista maintains an industrial services operation on Brandywine Avenue near the Otay Valley Road interchange, providing facilities support for commercial and government infrastructure. The firm's scope spans plant maintenance, mechanical system overhauls, and facility build-outs that require the same high-amperage distribution work handled by Arcelectric, Inc on commercial tenant-improvement projects. Classified under facilities support services, the Brandywine Avenue shop coordinates field crews for ongoing maintenance contracts across the greater San Diego region, including sites near the Medical Center Drive healthcare cluster anchored by Sharp Chula Vista Medical Center. HVAC system commissioning and ductwork fabrication on industrial retrofit projects often runs alongside the climate-control installations delivered by PROPER HVAC INC for commercial spaces requiring precise temperature regulation. Core capabilities include structural steel erection, process-piping fabrication to ASME B31.3 standards, and equipment rigging for machinery installations exceeding 10-ton lift capacity.
