A&S Engineering

A&S Engineering is a firm of architects, engineers, project managers, and support staff members. Over our 30+ year history, we have established a national reputation as a leading design firm with wide experience in residential, commercial and institutional work. Our practice has diversified over the years, however, this has not changed our firm attention to detail and commitment to quality design.

Our Results

Some of our completed projects include and are not limited to the razing and rebuilding of existing gas stations and retail facilities for our national clients (ie: Chevron, Circle K, Shell etc) and/or restaurants for national brands (ie: KFC, Pizza Hut, Baja Fresh, etc). We also have experience working for major developers of office buildings and public storage companies.

Kind Words From Our Clients

A & S Engineering was very instrumental in providing necessary architectural and engineering design to see this project thru its completion. In addition to handling the A/E portion of the project, A & S Engineering handled all work related to entitlement process thru final approval of the building permit.

Their knowledge of the area and regulators at the city provided significant assistance in reducing the entitlement process time which saved a number of months during the early development process of the subject site. I would highly recommend A & S Engineering for your entitlement and A/E services.
