our history

We were founded in 1991 by a core team of specialists who had worked together on laboratory and technical facility projects since 1982. Beginning with a small office in San Juan Capistrano, California, LCS brought a unique turnkey approach to the delivery of complex technical facilities. 

Our scope of services grew to include the maintenance and ongoing support of facilities, particularly complex laboratories; allowing us to service our clients from the conceptual phase of their facility to critical support after project completion.

Today, we continue to offer a distinctive integrated approach to project delivery, a method quickly accepted by our clients who desire a single source for the design, management, and construction of their technical construction projects; and value the collaboration fostered by a design-build or design-assist project delivery method.

Safety serves as the cornerstone for the delivery of every LCS projects. We’re dedicated to the safety and health of all stakeholders; from the construction team and your employees, to the surrounding community.

Safety is not mutually exclusive from the other benchmarks that mark a successful job. The fact is, safe jobs consistently meet or exceed the highest standards for quality, schedule, and cost control.

We explore and address health and safety considerations from initial planning through project completion, to deliver safe facilities for employees, site visitors, the surrounding community, and the environment. From preconstruction safety planning to the daily job hazard analysis performed by every team member, we bring a culture that was developed over 25 years while completing over 3,000 laboratory and technical facility projects.

Our team is qualified and committed to meet the compliance and safety standards of our clients.
