Our primary experience in aerospace construction has been our association with the Jet Propulsion Laboratory in Pasadena. Our current role at JPL is as their vendor for the inspection, testing and maintenance of all water-based fire protection systems in labs. However, our experience dates back to the 1970s and we have been active ever since with new construction projects, retro-fits and repair projects. We also have had a role in the construction and maintenance of the various fire protection systems at their Goldstone Deep Space Communications Complex in the desert outside of Barstow, California.
