Interactive Resources provides comprehensive structural engineering services for the design of new facilities as well as for rehabilitation and renovation projects.

We have provided services to developers, architects and owners in both the public and private sectors, and have had substantial design experience with timber, steel, and concrete. Our projects include office buildings, multi-unit residential complexes, churches, hospitals, commercial facilities, industrial buildings and bridges.

Interactive Resources also evaluates existing building framing to assess capability and suitability for the installation of rooftop solar collectors.

Some of our notable structural design projects include the Southern Marin Public Safety Building, Tinsley Manufacturing Facility, Hilltop Plaza Two Office Building , and the Point Richmond Tech Center.
