Vanderweil Engineers was founded in 1950 by Raimund Vanderweil, an Austrian immigrant with a mechanical engineering degree and several years of experience in mechanical contracting, engineering design, and heat transfer R&D. Today, we are a full-service engineering firm specializing in MEP and technology services for a wide variety of buildings, sustainable design, commissioning services, as well as central heating and chiller plants, power generation, and electrical transmission and distribution lines. With a staff of 450 located across ten offices, we are proud to be one of the largest independently-owned engineering firms in the country.

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 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, 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.
