Engineering Solutions

The engineering division of Excelsior Design has extensive experience performing managed-task design projects. Our mechanical & electrical team  applies sound engineering judgment and quality to each design project, including for commercial, industrial, and federal customers. Excelsior Design also has a broad skillset that can be employed in diverse applications such as chemical process systems, waste retrieval and processing systems, electrical distribution, and facility balance of plant systems. Our team uses system analysis, engineering studies and assessments, value engineering, feasibility studies, and alternate analysis studies to solve complex design challenges, including those challenges specific to highly regulated facilities and laboratories.
