Our Approach

Axiom Engineers℠ approaches design team organization on a per project basis. Project team members are assigned to match the demands of the project with their technical abilities. Each project is assigned to an Engineering Manager who reports to the Managing Principal. A Project Engineer is in direct charge of the project throughout the life of the project.

We continually update our engineering and production methodologies to meet or exceed industry standards. The entire staff, including branch offices, operates on the company network with the most current software. Our designers have mastered the most advanced CAD and Revit / BIM features. We also have standardized our office practices and procedures, from system sizing to specifications to production, thus assuring a higher degree of quality assurance and consistency.

Our History

Axiom Engineers℠ was founded by Richard G. Lee in 1970 with the philosophy that sometimes the best solution comes from the most fundamental principle. Raymond Cole, who had been working with the company since 1981, took over the leadership position of CEO and President upon the retirement of Richard Lee. Mr. Cole has been the company’s CEO and President since 1994.

The company has grown and expanded its services as well as its offices with locations on the Central Coast and in Northern California. Our experience in working with both public and private clients, multiple methods of project delivery, and our detail-oriented design and project management process, combined with a deep knowledge of the fundamentals provide an unmatched mix of practical high-end engineering. Critical to achieving our mission is cost-effective and timely delivery of high-quality design and engineering services. We achieve this through integration and transfer of the latest knowledge and by leveraging our unique intellectual capital for our client’s benefit.

Axiom Engineers℠ Capabilities

We cut to the heart of the matter and get inside our projects. We understand how the equipment we select really works. We are not “catalog” engineers specifying “black boxes”. We have designed complex, one-of-a-kind systems, processes, and machines successfully for over 45 years. We provide real, not “paper” experience. Because our employees have many years’ experience with us, each listed reference project is what we call “real company” experience. The people who did a project 10 years ago are likely available today for your current project.

From industry standard tools... to advanced engineering techniques...

Our CAD capabilities include AutoDesk’s AutoCAD, REVIT, and Architectural Desktop, as well as Bentley’s Microstation SE. Our design and engineering teams are fully trained and comfortable with all of the challenging aspects of CADD-based document production and can support custom-developed solutions and requirements for our clients’ exclusive needs.
