An efficient layout of administrative and engineering offices, service department, sheet metal fabrication shop, piping shop and storage areas situated in an industrial area with ready access to all major freeways in the Southern California area.

Accessibility is the keynote of Graycon’s offices and shops. This accessibility results in convenience and savings to service customers, clients, suppliers, and our diversified operations. Cost savings can be realized many times by a DESIGN BUILD team effort between the Owner, Architect, Engineer and Graycon by working together to simultaneously engineer and install the environmental systems for optimum efficiency, performance and economy. Project delays and loss of revenue are virtually eliminated by this practical approach, resulting in benefits to all concerned.

Full recognition is given to factors for satisfactory installation, such as: engineering and design; preparation of working drawings; realistic quotations; and nearly simultaneous fabrication and installation with minimum disturbance and maximum satisfaction to the most important tenants.
