What the plans reviewer is looking for
The foundation carries everything above it into the soil. Reviewers check that footing sizes, reinforcement and slab details match the soil conditions and the loads from the building, and that new work connects safely to anything existing.

Frequently asked questions about Foundation Design & Repair Plans
Do I need a soil report?
For new homes and commercial buildings it is often required or strongly recommended. For small additions we can sometimes use code-allowed values. We tell you which applies.
Can you design foundation repairs?
Yes. We design repair and underpinning details that a contractor can price and the building department can permit.
What foundation types do you design?
Slab-on-grade, post-tensioned slab review, pier and beam, spread footings, grade beams and equipment pads.
