Johnson DeBois & Forrest is a Structural Engineering and Code Consulting Firm that provides structural support services for a wide range of projects such as:

  • Custom homes, subdivisions, apartments, additions and remodels
  • Commercial buildings for office, retail, warehouse, winery, church and hotel establishments
  • Barns, riding arenas and agricultural buildings, custom pools
  • Third party plan checking for life/safety and structural design

We make every effort to keep the lines of communication open with our clients. We know how overwhelming and intimidating the building process can be. We have found that a client who is more informed about building code requirements will be less likely to become frustrated during the design process. We work closely with Architects, Builders, Designers and Clients to ensure design continuity.

We are committed to providing the highest level of service and maintaining professional and friendly relationships with all of our clients.
