Checking your home's construction
An Eichler in Rancho San Miguel has post-and-beam construction, wood siding and a slab foundation. We check your individual home's framing and foundation before planning alterations, rather than treating another house as a template.
Our inspection equipment includes 10× binoculars and a borescope.
Pre-pour inspections and sealed documentation
Before a foundation or retaining-wall pour, we check footing geometry and rebar placement against the drawings. We issue a sealed engineering report or letter for the applicable assessment or inspection.

Load-bearing wall analysis and beam calculation pricing
We charge $250 to $1,000 for a load-bearing wall analysis or beam calculation.
When retaining-wall permits apply
If your project includes a retaining wall supporting a surcharge, such as sloping ground or a parking area, Walnut Creek requires both a building permit and a site development permit. The City also requires that wall's design to be prepared by a licensed architect or registered civil or structural engineer.
What to Expect

Tell Us What You Need
A short call is enough for us to understand the project and what it will take.
-
Research First
We review what's already on file, records, plans, and prior work, before anyone heads out.
-
Clear, Written Price
You get the scope and the price in writing before any work starts. No surprises.
Some of what that looks like in the field:
- Provide repair recommendations and, when needed, code-compliant construction drawings.
- Inspect framing before insulation to check it against structural drawings and applicable code provisions.
What It Typically Costs

FAQs
An architectural engineer focuses on building systems integration including mechanical and electrical aspects. A structural engineer specializes in the integrity of load-bearing elements, calculating forces on beams, foundations, and framing. For home projects involving walls or foundations, a structural engineer provides targeted analysis and stamped drawings.
ChatGPT can explain general concepts and outline steps but cannot perform accurate structural calculations, site-specific load analysis, or produce stamped engineering documents. Real structural work requires licensed professionals who visit the site, measure conditions, and apply local codes. AI tools lack the accountability and verification needed for safety-critical decisions.
AI assists with preliminary calculations and drafting but cannot replace licensed structural engineers. Engineers must conduct physical inspections, verify site conditions, account for local codes, and take professional responsibility for stamped plans. Regulatory requirements and liability concerns ensure human oversight remains essential for residential structural projects.
