Lot Grading & Pad Preparation

A building pad has to be level, firm and drained before anything goes on it. Grading moves earth to the right shape, and compaction makes it strong enough to carry a structure. NorTech connects you with a verified licensed earthwork contractor who studies the plans and the lot and bids the grading in writing, including testing and erosion control.

Plans, surveys and elevations

Grading follows a plan that shows existing and finished elevations, drainage paths and the building footprint. The contractor sets stakes from the survey and checks grades regularly with laser or GPS equipment. Cut and fill balance matters: moving soil around the site is cheaper than importing or exporting large volumes. Questions about neighbors, easements and setbacks are resolved before the first scoop. Bring the grading plan, the soils report and the survey to the first meeting, so the contractor can compare them with what they see on the ground.

Compaction, testing and stable pads

Fill soil is placed in thin lifts and compacted with rollers to a specified density, often verified by a soils engineer. Poorly compacted fill settles and cracks slabs. Soft or organic soil is removed. Tests and reports are kept for the building department and lender. Weather affects soil moisture, so the schedule allows for drying or wetting as needed. Ask who orders the compaction tests and how quickly results come back, because the pad cannot be signed off until the density numbers pass.

Drainage, erosion control and handoff

Rough grading directs water away from the pad through swales and berms, and temporary erosion controls such as wattles and silt fence keep soil on site during rain. Many jurisdictions require a stormwater plan. At handoff, the pad is staked for foundation work, with elevations documented. Ask for photographs and compaction reports for your records. Keep the soils engineer’s letter, compaction reports and photos in one folder, since the inspector and the lender may both ask for them.

Frequently asked

Lot Grading & Pad Preparation — common questions

Slope, soil, volume of earth moved and access vary by site. A contractor needs the plans and a site walk to price it. Ask your provider to confirm the details in writing before work starts.

Often, especially for larger volumes or hillside lots. The contractor can help with the application and erosion control plan. Keep copies of invoices and reports with your home records for future reference.

A soils engineer or testing lab measures density in the field and issues reports. Keep them for the building inspector and lender. Timing can vary with weather, access and permits, so ask for a realistic window.

A small building pad can be graded in a few days, while a larger lot or a hillside site may take several weeks. Soil testing, rain and drying time between lifts set the pace more than machine time does.

Many places require erosion and sediment control during grading. The contractor installs and maintains them. Timing can vary with weather, access and permits, so ask for a realistic window.

The contractor guarantees its grading to the agreed elevations for 60 days. Settlement from unreported soil conditions or later modifications by others is not covered.
