Which Site Work Your Project Actually Needs

July 1, 2026

Excavation is a catch-all word for a stack of very different jobs, and the one you need depends entirely on where your project starts. A raw wooded acre and a bare, staked lot call for almost opposite first moves. Here is how the common services fit together, in the order a site usually needs them.

Start by Reading the Lot

Before any machine moves, someone has to look at the ground, the soil, the access, and the plan. A parcel with trees needs clearing. A pasture may only need topsoil stripped. A lot with a steep fall toward the building line needs a drainage answer before anything else. This walk-through is also when the 811 locate gets called, so buried gas and electric lines are marked two business days ahead.

Clearing and Grubbing Come First on Raw Ground

If the lot is wooded or overgrown, clearing opens it and grubbing pulls the stumps and roots out below grade. Skipping the grubbing is a classic mistake, because buried roots rot and leave voids that undermine fill later. If you are starting with timber or heavy brush, land clearing is almost always the first line item.

Grading Sets the Stage for Everything Above

Once the lot is open, grading shapes it to the plan. Topsoil is stripped and stockpiled, cut and fill balances the earthwork, and the subgrade is compacted to a tested density. Good grading is really about water, since positive slopes away from the foundation are what keep a finished pad dry. This is the stage that decides whether a slab stays flat for decades.

Digging and Trenching Follow the Grade

With the pad set, foundation excavation cuts the footings, crawl space, or basement to plan depth, and utility trenching runs the water, sewer, and electric lines. Any trench 5 feet or deeper gets a protective system under OSHA Subpart P, no exceptions. These digs happen after grading because they reference the finished elevations.

Fill and Base Finish the Job

Where the plan calls for it, engineered structural fill goes in controlled lifts and gets compacted to spec, and crushed aggregate base is placed under gravel drives over geotextile fabric. Screened topsoil returns over finished areas so the lot is ready to seed. Done in the right order, the site holds up.

Calmodern provides land excavation in Bentonville, AR, from the first cut to the final graded pad. Site preparation, land clearing, foundation and basement digs, utility trenching, drainage and erosion control, and structural fill all run under one crew and one schedule. We put hydraulic excavators, crawler dozers, skid steers, and tandem dump trucks on residential lots and commercial pads alike. Much of that work happens off Walton Boulevard and in the newer subdivisions near SW 14th Street, inside the 72712 and 72713 ZIP codes.

Every parcel starts different. A wooded lot needs grubbing and haul-off before a single string line goes down, while a bare pasture near Moberly Lane may only need topsoil stripping and cut-and-fill to reach the pad elevations on the grading plan. We read the site, the soil, and the drawings before the machines move, so the dirt work matches what the engineer and the foundation crew actually need.

The base and fill we bring to the job decide whether a slab or driveway holds up. We place engineered structural fill in controlled lifts, run a nuclear density gauge against the Proctor number, and lay geotextile separation fabric and crushed aggregate base under gravel drives. Screened topsoil goes back over finished areas so the lot is ready to seed. Nothing gets buried that should not be, and nothing gets skipped to save a day.

What makes our approach different is that we treat grade and drainage as the whole point, not an afterthought. Water has to leave a site the right way, so we shape positive slopes away from every foundation, cut swales where the plan calls for them, and set silt fence and inlet protection to keep sediment on your property. That discipline is why a Calmodern pad in the Market District still drains clean two winters after the concrete truck leaves.

  • Grade and drainage firstWe shape positive slopes and swales so water leaves every foundation the right way, backed by our density and drainage guarantee.
  • Compacted to a real numberStructural fill goes in lifts and is tested to 95 percent of maximum dry density, not eyeballed.
  • Dig it by the bookEvery trench 5 feet or deeper gets sloping, benching, or a trench box per OSHA Subpart P, with 811 locates called first.
  • One crew, start to finishClearing, grading, digging, trenching, and fill from a single local team, so nothing falls between trades.

    Site Preparation and Grading

    Topsoil stripping, cut and fill, and rough-to-finish grading that shapes a raw parcel to the engineer's plan, setting pad elevations, drainage slopes, and a compacted subgrade ready to build on.

    Land Clearing and Grubbing

    Removal of trees, brush, and undergrowth, then grubbing of stumps and roots below grade, with haul-off or on-site mulching to open a wooded lot for construction.

    Foundation and Basement Excavation

    Footing, crawl space, and full basement digs to plan depth and dimension, with over-dig for forms, spoil management, and a level, compacted bearing surface for concrete.

    Trenching and Utility Excavation

    Trenching for water, sewer, gas, electric, and drainage lines with proper bedding and backfill, using sloping, benching, or a trench box in cuts 5 feet and deeper per OSHA.

    Drainage and Erosion Control

    Positive grading away from structures, swales, French drains, and detention features, plus silt fence, inlet protection, and erosion blankets that meet stormwater (NPDES and SWPPP) rules.

    Driveway and Road Base Prep

    Subgrade compaction, geotextile separation fabric, and crushed aggregate base placed to build a stable, well-draining gravel driveway, private road, or paving-ready subbase.

    Pricing Guide for Each Kind of Site Work

    Excavation pricing tracks the amount of dirt moved, the access, and the soil more than anything else. Light brush clears cheap, heavy tree cover with stump grubbing runs higher, and rock or a high water table adds cost to any dig. The ranges below are typical for the Bentonville area, and we put the firm number in a written quote after we walk the site.

    Details Clients Want Before Booking

    How much does it cost to excavate and grade a lot in Bentonville?
    It depends on how much dirt moves, the access, and the soil. Land clearing runs $1,400 to $6,200 per acre, grading lands near $1.40 per square foot, and rock or a high water table adds cost. We give a firm written quote after walking the site.
    Do you call 811 before you dig?
    Always. We file the 811 Call Before You Dig locate and wait the required two business days before any trench or foundation excavation, so gas, electric, and communication lines are marked before a bucket touches the ground.
    How deep can a trench be before OSHA requires protection?
    Any trench 5 feet or deeper needs a protective system, which means sloping, benching, or a trench box. Our competent person inspects each excavation daily, and we work under OSHA 29 CFR 1926 Subpart P on every job.
    What does your density and drainage guarantee cover?
    We guarantee two things you cannot see from the curb. Structural fill is placed in lifts and tested to 95 percent of maximum dry density by Proctor, and finished grade sheds water away from your foundation. If a tested pad or a graded slope fails to hold, we come back.
    What kinds of projects do you take, from lot clearing to basements?
    Land clearing and grubbing, site preparation and grading, foundation and basement digs, utility trenching, drainage and detention basins, and gravel driveway base. Residential lots and commercial pads both fit our equipment.
    Do I need a grading permit or a SWPPP?
    Sites that disturb one acre or more generally need a Stormwater Pollution Prevention Plan under the NPDES construction general permit, and Bentonville may require a grading permit. We help you sort out what the plan and the county need before we mobilize.
    What happens to the topsoil and dirt you strip off?
    Usable topsoil gets stripped and stockpiled, then screened and spread back over finished areas so the lot is ready to seed. Excess spoil is hauled off, and engineered structural fill is imported and compacted where the plan calls for it.
