Foundation Engineering & Design Services
Professional foundation engineering for new construction, repairs, and assessments. Our licensed structural engineers design safe, cost-effective foundation systems tailored to your site conditions and building requirements.
What is Foundation Engineering?
Foundation engineering is critical to building safety - the foundation transfers all building loads to the ground and must be properly designed for site-specific soil conditions, seismic forces, and building loads. We provide foundation design for new construction, assessment and repair design for existing foundations, and specialized solutions for challenging sites. Our engineers work with geotechnical reports to design foundations that perform properly throughout the building's life.

How It Works
Our streamlined process for foundation engineering
Initial Consultation
Discuss project requirements, review site information, and determine if a geotechnical investigation is needed (or review existing report).
Site Assessment
For existing foundations: inspect current conditions, document problems, and assess causes. For new construction: review geotechnical data and site constraints.
Geotechnical Coordination
Review geotechnical report recommendations for bearing capacity, lateral resistance, expansive soils, liquefaction, and other site-specific concerns.
Foundation Design
Engineering design of foundation system including sizing, reinforcement, and all details per code requirements and geotechnical recommendations.
Drawing Production
Create detailed foundation plans showing all elements needed for permit approval and construction.
PE Stamping & Delivery
Quality review, preparation of calculations, PE stamping, and delivery of permit-ready documents.
Permit Support
Response to building department plan check corrections and coordination for approval.
Construction Phase
Pre-pour inspection of reinforcement placement, contractor questions, and construction support as needed.

Frequently Asked Questions
Common questions about foundation engineering
Do I need a geotechnical report for foundation design?
Most jurisdictions require geotechnical reports for new construction, and they're essential for proper foundation design. The geotechnical report provides soil bearing capacity, recommendations for foundation type, and identifies issues like expansive soils, liquefaction potential, or high water table. We can recommend geotechnical engineers if you need one.
What causes foundation problems?
Common causes include: expansive soils that swell and shrink with moisture changes, poor drainage allowing water to undermine foundations, inadequate original design, soil settlement or consolidation, root intrusion from trees, and earthquake damage. Proper identification of the cause is essential for effective repair design.
How much does foundation engineering cost?
Foundation engineering for new residential construction typically costs $2,500-$6,000. Foundation assessment and repair design ranges from $2,000-$8,000 depending on complexity. Hillside foundations or challenging sites may cost $5,000-$15,000+. Commercial projects vary widely based on size and complexity. We provide detailed quotes after understanding your project.
What are the signs of foundation problems?
Warning signs include: cracks in walls, floors, or exterior; doors and windows that stick or don't close properly; uneven or sloping floors; gaps between walls and ceiling/floor; cracks in the foundation itself; and separation of exterior brick or siding. If you notice these signs, a foundation assessment is recommended.
What foundation types do you design?
We design all foundation types including: spread footings (most common residential), continuous footings, post-tension slabs (for expansive soils), conventional reinforced slabs, pier and grade beam systems (for hillsides or poor soils), drilled shaft/caisson foundations (for deep bearing), and mat foundations (for heavy loads or poor soils).
Can a damaged foundation be repaired?
Yes, most foundation problems can be repaired. Common repair methods include: underpinning with piers to stabilize settling foundations, carbon fiber reinforcement for cracked walls, epoxy injection for crack repair, and excavation with waterproofing for water intrusion. The appropriate repair depends on the problem and cause.
How long does foundation work take?
Engineering design takes 2-3 weeks for typical projects. Construction time varies: new residential foundations typically take 1-2 weeks to form and pour, while foundation repair projects range from a few days to several weeks depending on complexity. Post-tension slabs require additional curing time before stressing.
Do you provide construction inspection?
Yes, we offer pre-pour inspection of foundation reinforcement to verify proper installation before concrete is placed. This is especially important for complex foundations or critical projects. We can also provide periodic inspection during foundation repair work. These services can be included in scope or added as needed.
