Airport & Aviation Engineering

Designing Infrastructure That Keeps You Moving.

With five decades of experience, Interstate Engineering brings deep expertise and trusted partnership to airports across the region. Our work spans the full life cycle of aviation infrastructure, boundary surveys, airport layout plans, and hangar and terminal buildings to runway and apron construction, airfield lighting, and navigational aids.

We serve multiple aviation facilities on an ongoing basis, working with both federally funded and non-federally funded airports. Our team understands FAA procedures, guidelines, and funding systems inside and out. Whether it’s updating a master plan or designing a snow removal equipment building, we tailor our approach to meet safety, compliance, and operational needs on time and on budget.
