Structurally sound engineering solutions.
Interstate Engineering delivers structural design for buildings and bridges. Most projects call for our expertise in surveying, studies and risk assessment, inspection and rehabilitation. No matter the material, we can design it. We are well-versed in building concrete, masonry, steel, and timber structures.
Our bridge design portfolio ranges from the preparation of project development reports to construction observation and surveying. We provide experience in railroad grade separation projects, river crossings, and highway grade separation over interstate highways. In addition to new structures, we also develop designs for structural rehabilitation where needed. Interstate Engineering provides complete structural engineering services for foundations, reservoirs, and buildings.
