Earthwork & Grading.
Site preparation, excavation, and grading that set the table for every trade that follows.
WIL-Surge Electric is an excavation and grading contractor for commercial sites across Wisconsin. Our in-house crews handle site preparation, excavation, and mass and fine grading with our own equipment fleet, establishing the right foundation for the building and every trade that follows.
Earthwork prepares each property for electrical and mechanical infrastructure before vertical work starts. Because we also self-perform the underground, concrete, electrical, and mechanical scopes, the ground is shaped by a team that knows exactly what will be built on it.
Site Preparation & Excavation
Site preparation starts with clearing the property and stripping topsoil, so construction begins on workable ground. From there, our crews handle excavation for buildings, equipment, and utilities, and build up the building pads that structures sit on.
Backfill is placed and compacted, so the ground under slabs, foundations, and paving stays stable once the building is up. The same crews coordinate with our underground utility teams, so trenches and excavations for power, communications, and water lines fit into the site work schedule instead of fighting it.
Grading & Drainage
Mass grading moves earth to bring a site to the elevations in the plans. Fine grading then sets the final surface for building pads, parking areas, and landscaped ground, so the next trade starts from accurate elevations.
Good grading also decides where water goes. Our crews set slopes so water drains away from buildings, protecting foundations and keeping standing water off the site.
Reading a Grading Plan
A grading plan is the map for everything earthwork crews do. It shows existing ground elevations, usually as contour lines, alongside the proposed elevations the finished site needs to reach. Where proposed ground sits higher than existing, fill has to be brought in or moved over; where it sits lower, soil has to be cut away. Comparing the two across the site shows how much earth has to move and where it needs to go.
The plan also sets the details that matter most once the building is up: finished floor elevations, the pad the structure sits on, and the slopes that carry water away from foundations. Small differences in those numbers can mean water standing against a wall or a sidewalk that doesn't meet the door.
Our crews work from those elevations as mass grading brings the site close and fine grading sets the final surface, so the next trade starts from the numbers on the plan.
Soil & Compaction Testing
Soil is not a uniform material. Clay, sand, gravel, and organic topsoil all behave differently under a load, and a single site can hold several of them. Before design is finished, a geotechnical investigation typically samples the ground and recommends how it should be prepared, including which soils can stay, which need to be removed, and how fill should be placed.
Compaction is how loose soil becomes a stable base. Fill is generally placed in layers, called lifts, and compacted to the density the project specifications require, at a moisture content that lets it compact properly. Soil that is too wet or too dry may not reach the specified density no matter how much effort goes into it.
On many projects, an independent testing agency checks density in the field as the work progresses, so problems are caught while they are still easy to fix. Getting compaction right under slabs, foundations, and paving is what keeps the ground from settling once the building is up.
Equipment Fleet
Our earthwork crews work out of our own equipment fleet. That keeps equipment and the crews who run it under one company, scheduled around your project alongside the rest of the scope we carry.
Sequencing Site Work With Other Trades
Earthwork sets the pace for the rest of the site. Rough grading has to be close enough for underground crews to trench at the right elevations, underground lines have to be installed and backfilled before building pads and slabs are finished over them, and fine grading usually comes back near the end, once heavy equipment and deliveries are no longer crossing the finished surface.
When those steps are split among separate subcontractors, every handoff is a chance for a crew to wait or for finished work to be disturbed. Because our earthwork, underground utility, and concrete crews all work for WIL-Surge Electric, the sequence is planned as one schedule, and a change in one scope is accounted for in the others before it reaches the field.
That coordination is most valuable on tight sites and compressed schedules, where the order of site work decides whether vertical construction starts on time.

Once the site is graded, our concrete crews pour the foundations and transformer pads, and our power distribution crews set the equipment that sits on them, all under one contract.
