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.
