Design-Build La Mirada Office Park – Vista, CA

Orion designed and built its office headquarters to house company-wide operations in Vista, CA. The 15,800 square foot building sits atop a 1.5 acre site with over 20,000 square feet of reinforced concrete parking for equipment, indoor mechanics warehouse and machine shop. Orion also performed substantial retaining wall construction and irrigation installation around the site.


Design-Build Domestic Water Piping at Building 3, Marine Corps Recruiting Depot – San Diego, CA

This design-build project required the design and reconstruction of restroom facilities in Building 3, an administration building at MCRD.  Orion removed and replaced toilets, sinks, and behind-the-wall plumbing. The walls within the remodeled restrooms were furred out to install new fixtures meeting plumbing code.

To ensure critical command command functions could continue, the building remained in operation during construction. Orion sequenced its work and  coordinated with building staff to ensure they could continue working.

Design-Build Drain/Waste/Vent Replacement Buildings 619 & 625, Marine Corps Recruiting Depot – San Diego, CA

This Design-Build project involved the complete rehabilitation of two hotel buildings’ plumbing and mechanical systems.  The deteriorating drain-waste-vent system had caused several rooms to be water damaged, which Orion repaired as well. The hotel was in active use, requiring work be completed in phases. This project extensively utilized cured-in-place epoxy liners to rehabilitate inaccessible piping that was intertwined within the buildings’ structural grade beams. To line the pipes, Orion accessed them through excavations outside the buildings or mechanical chases. The fixtures within the buildings were similarly removed and later replaced so pipes could be re-lined.
