Yes, we specialize in difficult deck projects. Whether you want to expand an existing deck or build a new one over a steep slope or lakefront property, our structural engineering expertise ensures safe and code-compliant cantilevered designs. We handle all aspects from initial consultation through permitting, including structural analysis for the unique loads and soil conditions common in the Willamette Valley.

When you're planning a renovation—like removing a load-bearing wall or adding a second story—our structural analysis ensures the existing framing can support the changes. Andy will perform a site visit (complimentary within the Portland metro), review the structure, and provide calculations and drawings needed for permits. This service is crucial for renovations in older Oregon City homes that may have outdated construction.
