Bay & Associates goes far beyond merely providing the plans and specifications our clients need to get a building permit. We bring the breadth and depth of experience and expertise our clients need—whether they are architects, developers, leasing brokers and property managers, or design-build contractors—to achieve an outstanding, holistic solution.

We have the expertise to handle virtually any type of project because we’ve done it before. We excel at quick turnaround projects because throughout our organization we have the right people working together to get the job done.

We provide the full range of specialties you expect from a dynamic MEP engineering firm, including commercial office, data center, light industrial, educational/institutional, public, medical office, condominium, hospitality, retail/mixed use, restaurant/food service, and corporate facilities, just to name a few.

To enhance our engineering services, Bay provides design and documentation for USGBC LEED® and Austin Green Building Program projects. And we have an experienced contract administration staff to ensure the plans we develop are being implemented according to specs.
