Level 10 Construction

Level 10 Construction is a Sunnyvale, Calif., general contractor that eight industry veterans started in 2011. It’s grown into one of the busier builders in Silicon Valley, with offices in San Francisco, San Diego, Sacramento and Austin, and it works across life sciences, advanced technology, corporate campuses, healthcare, education, civic work and housing. Its client list leans on repeat developers like Jay Paul Co. On the Peninsula, Level 10 built Avia Labs at Millbrae Station for Longfellow Real Estate Partners, a $200 million, six-story life science building squeezed between an active BART line and an overpass under SFO’s height limits. It finished in November 2025 on time and on budget, and ENR West named it a 2026 Best Project.

Self-perform capacity is the part of Level 10’s operation that a subcontractor or owner notices first. The firm places the majority of structural concrete on its own jobs, and its crews also take on soft demolition, rough carpentry, interim life safety measures, infection control measures, pedestrian barricades and general cleanup. Level 10 is a signatory contractor with the carpenters, laborers and cement finishers unions, which is what sustains that in-house workforce. Keeping concrete in-house means the frame schedule sits with the general contractor rather than being handed down the chain.

Beyond field work, the company organizes its preconstruction and delivery offering into named services: preconstruction, lean construction, design-build, design assist and design-build MEP+, building information modeling, and sustainability. The MEP+ line matters on technology and life science jobs, where mechanical, electrical and plumbing scope usually sets the critical path. Level 10 markets design-assist and design-build arrangements for those trades rather than treating them as ordinary bid packages.

Safety metrics are published rather than implied. The company reports an experience modification rating of 0.49 and more than 10 million work hours without a lost-time incident. The Construction Employers Association of California gave it Excellence in Safety awards in 2020, 2021, 2022, 2023 and 2025, and President’s Safety awards in 2023 and 2025. ConstructSecure issued a Gold safety award in 2020. The firm staffs a dedicated bench of safety managers and coordinators rather than loading the duty onto project engineers.

One illustration of how it handles congested sites comes from the Springdale Green development in Austin, where four tower cranes, two crawler cranes and two mobile cranes were in use at the same time, with the simultaneous lifts managed through coordinated communication across the crews.

On locations and licensing: the Sunnyvale headquarters is at 1050 Enterprise Way, Suite 250, with further offices at 577 2nd Street in San Francisco, 12626 High Bluff Drive in San Diego, 1023 Springdale Road in Austin, and 2250 Douglas Boulevard in Roseville, which the site lists as its Sacramento office. The company carries California contractor license number 967797, and subcontractor inquiries are routed through a dedicated page rather than the general contact form.
