Our Firm

Engineering with Purpose

Vanderweil specializes in MEP/FP engineering, technology design, sustainability consulting, commissioning, and power engineering. We serve our clients from multiple offices across the U.S. Our 500 professionals are committed to enhancing the wellbeing of our planet and its occupants.

Our character and culture stem from our long history in the field—over 75 years and thousands of projects. An important aspect of this history is our immense storehouse of intellectual capital and staff expertise – which benefit our projects.

We are a good place to work: our staff longevity has increased step by step with our experience. A third of our people have over 10 years of seniority with us, and almost half of those have over 20 years.

We provide an outstanding learning environment and a career development pipeline that leverages staff longevity and expertise. This pipeline ensures a continuum of knowledge transfer from mentor to mentee, from team to team, and from generation to generation.

Our project teams include senior engineers, younger PEs, and engineers still in development. Clients can be assured of capitalizing on our top-level expertise combined with our production horsepower.

After 75 years, we remain an independent firm. Any staff member, client, or industry vendor can walk into the CEO’s office and be assured of a definitive response and feedback.

Our aim is to be here for the long term. We have every incentive to maintain an exceptional company and to provide our clients with a top-quality relationship, work product, and end-result.

Why Vanderweil?

Our goal is to provide innovative, customized solutions and responsive service to each of our clients, which has enabled us to achieve a high repeat business ratio. We treat each of our building projects as an opportunity to reduce carbon emissions and improve the health and wellness of its occupants.

Our Employees Are Our Most Valued Resource

We believe that our work gives us a unique opportunity to help our clients, our employees, and the environment, and to enhance the built environment. Our employees are our most valued resource, and we are committed to their professional development and success. We believe in diversity, equity and inclusion in the engineering community, and focus our efforts in community engagement and company activities to support this belief.

With a staff of 500 located across multiple offices, we are proud to be one of the largest independently-owned engineering firms in the country.
