Whether your project is large or small, we have the experience and knowledge you need to complete the project on time and within budget. As a small engineering firm, you would work directly with the professional engineer responsible for making you project a success. Lack of communication is the number one reason for failure, at Seaport, we pride ourselves on providing proper correspondences, reports, and photographic documentation to ensure all members of the project team are informed through the entire process.

We hope that you will contact Seaport Engineering for a review of your project needs.
