Mass Grading and Earthwork Plan
Engineered grading plans and cut and fill calculations for large sites, pads and land development.
What the work involves
A grading plan sets finished elevations for building pads, roads and lots, balances cut and fill, and routes drainage. The engineer computes earthwork quantities, specifies compaction requirements with the geotechnical engineer, and prepares erosion control phasing. Most jurisdictions require a grading permit above certain volumes of earth moved or disturbed area.
Local conditions we plan for
- Expansive clay soils
- Tornadoes and severe storms
- Induced seismicity linked to wastewater injection
- Flash flooding
Building code: 2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Rules adopting newer editions were pending with a September 14, 2026 effective date.
When you need it
- Moving large volumes of soil for building pads or lots
- Site exceeds the local grading permit threshold (often measured in cubic yards)
- Importing or exporting fill
- Creating level pads on sloping land
- Contractor needs earthwork quantities for bidding
Frequently asked questions
How much does mass Grading and Earthwork Plan cost?
Across the US, mass Grading and Earthwork Plan usually costs $3,000 to $50,000. Estimate. Scales with site size and complexity; small pads are a few thousand dollars and large developments much more. HomeAdvisor's $65 to $200 per hour civil rate applies to hourly work.
How long does mass Grading and Earthwork Plan take?
Plan on 2 to 8 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 mass Grading and Earthwork Plan?
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 Oklahoma?
Engineers practicing in Oklahoma are licensed by the Oklahoma State Board of Licensure for Professional Engineers and Surveyors. 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 Oklahoma?
2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Rules adopting newer editions were pending with a September 14, 2026 effective date. 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 Oklahoma?
Common issues include expansive clay soils, tornadoes and severe storms, induced seismicity linked to wastewater injection and flash flooding.
