Checking a proposed wall opening
We first confirm whether the wall carries load. We trace the load path above and below the proposed opening and measure the spans and framing. The check extends beyond the wall you want to remove: we need to understand how its load reaches the structure below.
We calculate the applicable dead, live, snow and point loads. We also determine the tributary area, the area whose weight would be carried by the proposed beam. The width of the opening alone does not give us the information needed to determine the beam's load.
Measuring cracks
We use digital calipers to measure crack width and a crack monitor to track changes over time. Those measurements give us a record to compare rather than relying on whether a crack looks larger. Walnut Creek's large daily temperature range is also a condition we consider during the assessment.
Checking foundation and below-grade conditions
Where Clear Lake soil is present, we check for poor drainage and seasonal groundwater when assessing foundations and below-grade work. The water table can be several feet down in late summer and rise close to the surface during wet winter months. A summer assessment needs to account for those wetter conditions.
Liquefaction zones cover much of Ygnacio Valley and major drainages, including Tice and San Ramon Creeks. In those areas, we treat earthquake-related ground movement as a site-specific concern, not a condition we assume is the same across Walnut Creek.

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:
- Prepare a written assessment or permit-ready drawings that document findings, engineering conclusions, and recommended actions.
- Discuss the reported symptoms, the home's construction and age, previous foundation work, and the purpose of the evaluation.
What It Typically Costs
Typical ranges, not a fixed price - the exact number is confirmed in writing before work starts.
$200–$600
$350–$900
FAQs
Yes when you need to confirm load-bearing walls, evaluate foundation issues, or obtain stamped plans for permits. An engineer provides documented analysis of loads, framing, and safety that protects against costly mistakes. For minor cosmetic concerns, a general contractor may suffice, but any structural modification or insurance claim usually justifies the fee.
ChatGPT can explain basic concepts and suggest typical beam sizes, but it cannot perform site-specific engineering calculations, verify field conditions, or stamp drawings. Structural analysis requires licensed professional judgment, measured loads, material properties, and code compliance that AI cannot legally or reliably provide for construction decisions.
An architectural engineer focuses on building systems such as HVAC, lighting, and acoustics while coordinating overall design. A structural engineer specializes in the load-bearing frame, foundations, and lateral forces. Both may work on the same project, but only the structural engineer calculates beams, columns, and foundations for safety and code compliance.
They evaluate how a building carries loads, inspect foundations and framing, and design or review beams, columns, and connections. For renovations they confirm load paths, calculate required sizes, and provide stamped drawings. They also document existing conditions with measurements and photos to support permits, repairs, or insurance claims.
Hourly rates commonly fall between $100 and $250 depending on experience and location. Simple consultations or site visits may be billed hourly, while full inspections or plans are often quoted as flat fees. Travel time, report writing, and any required calculations can increase the final cost beyond the base hourly rate.
