California
Pavement Design and Evaluation
Engineered asphalt and concrete pavement sections for roads, parking lots and driveways, plus failing pavement assessments.
What the work involves
Pavement design sets layer thicknesses based on subgrade soil strength and expected traffic, especially truck loads, which do far more damage than cars. Engineers also evaluate cracked, rutted or potholed pavement to decide between crack sealing, mill and overlay, full-depth reclamation or reconstruction. Municipalities use pavement management programs to rate road condition and prioritize repairs across their network.
Local conditions we plan for
- High seismic hazard and active faults
- Wildfire in the wildland urban interface
- Landslides and debris flows on steep slopes
- Coastal bluff erosion and sea level rise
Building code: California Building Standards Code (Title 24), based on the 2024 IBC and IRC, statewide (ICC adoption chart, April 2026).
When you need it
- New road, parking lot or truck loading area
- Pavement failing within a few years of paving
- Truck traffic increasing at a facility
- Municipal pavement management program
- Deciding between overlay and reconstruction
Frequently asked questions
How much does pavement Design and Evaluation cost?
Across the US, pavement Design and Evaluation usually costs $1,500 to $25,000. Estimate. Single parking lots are at the low end; network pavement management studies for municipalities cost more.
How long does pavement Design and Evaluation take?
Plan on 1 to 6 weeks from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Do I need a licensed PE for pavement Design and Evaluation?
In most US jurisdictions, yes. When the work needs a permit, the plans, calculations or report usually must be sealed by a Professional Engineer licensed in the state where the project is located. Every deliverable we issue for permit is sealed that way.
How do I verify an engineer's license in California?
Engineers practicing in California are licensed by the Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG). You can confirm a license number and its status in the board's public license search before you sign a contract.
Which building code applies in California?
California Building Standards Code (Title 24), based on the 2024 IBC and IRC, statewide (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
What site problems do engineers see most in California?
Common issues include high seismic hazard and active faults, wildfire in the wildland urban interface, landslides and debris flows on steep slopes and coastal bluff erosion and sea level rise.
