ABOUT US - An Energy Engineering Company

Character. Relationships. Integrity. Expertise. Since 1980.
At Tetra Tech Rooney (REI), our reputation as a highly respected, key solutions provider for the energy industry is rooted in our expertise, character and relationship building.


REI, a Tetra Tech company, has been delivering comprehensive pipeline engineering and facilities construction solutions to the energy industry for over 30 years. We take pride in our versatility and the opportunities we have in cultivating new techniques for challenging projects. At REI, it is less about hierarchy and more about accountability in approaching every project, using the foremost technology, whereby the clients pay less and the job is completed as efficiently and cost effectively as possible. Routinely poised to find the best solutions for our clients, both economically and logistically, REI continually invests in the top talent in our field and the latest technological tools and techniques to ensure that the work we perform meets the highest of standards.


Tetra Tech Rooney was founded on the idea that business and integrity should walk hand in hand, a conviction that has molded the character of our company. We believe in working as a team, principal and staff, solving problems for our clients using the most innovative, cost-effective solutions in the pipeline engineering and the construction field since 1980.


We operate with the conviction that teamwork is paramount at REI, reflected in the relationship building that naturally evolves with our clients through our open access communication, and the fact that one of our highly experienced principals (collectively touting nearly 200 years of industry expertise), oversees all facets of every project from inception through completion. In this highly personalized one-on-one model, the collective team is focused on the right solution versus the easy solution.

Our linear hierarchical structure is simply a formula for collaborative innovation and also the very foundation of our firm's success. REI's workflow is harmonized with the firm's size, allowing for optimal efficiency, communication and performance throughout every project, every time.
