We are a small full-service structural engineering firm established in 1997 by Arthur Tan. Practicing structural engineering for 25 plus years, he has vast experiences in design of residential, commercial, and institutional structures. Please download a copy of his resume for additional information.

We utilize AutoCAD, Revit, SketchUp, SAFE, ETABS, SAP2000, ENERCALC, RISA to generate structural drawings and calculations needed by other consultants, contractors, and various city, county, and state agencies.

We start the design process by carefully listening to our clients' needs, and then we apply the 'Goldilocks principle' in our design...'Not too hot, not too cold, just right'. Also having extensive hands-on experiences in construction, we understand the detail facets of the construction phase. Our design solutions always maintain the architectural design intents while being practical and cost-effective.
