Haley & Aldrich

From a foundation of technical excellence, Haley & Aldrich seeks to create more value for our clients while reducing their overall project costs. We use novel approaches to engineering and environmental challenges, including more efficient processes and new ways of applying technology. In some cases that means not doing things the way they are usually done in our industry, or the way our clients typically approach a project.

We also innovate in our practice by looking beyond the technical challenges to consider how various stakeholders impacted by a project will measure success. We consider the needs of various regulatory agencies as well as the impact on the environment, communities, and neighborhoods. We factor those needs with our deep understanding of the value our clients desire to create for their organizations and stakeholders. In this “whole-system approach,” the more stakeholders who are satisfied, the more successful and more sustainable a project will be.

Core to how we operate is our commitment to having our best people on the most challenging opportunities, and the right people doing the right work—safely. To do this, we’ve built one team that works together across all U.S. geographies to solve complex problems above and below ground. We serve clients from multiple offices across the country while providing consistent and seamless delivery.
