Weir Environmental Is Now NV5


In September 2016 NV5 acquired Weir Environmental (Weir), a Louisiana-based full-service industrial hygiene and environmental consulting firm serving a wide range of clients globally. Weir’s professionals have been first responders to Hurricanes Katrina, Gustav, Ike, Irene, Isaac, and Sandy, in addition to other major flooding events and tornadoes, and continue to provide cleanup, restoration, and property loss consulting services to many of the affected areas. Their clients include local, state and federal municipalities and institutions; insurance, real estate, financial and banking institutions; universities and schools; energy and oil industries; and retail/commercial businesses. Weir’s reputation for responsible project management and oversight, professionalism, and integrity, combined with a genuine concern for its clients’ interests and safety, is key to the firm’s success.

Weir Environmental joined NV5 to expand our capabilities and ability to serve our clients. While our look will be changing, our commitment to delivering value and expertise to our clients will not. We are now NV5, and together we will continue to develop solutions that enable our clients to achieve more.
