The short answer

Sitework is the civil construction that prepares land so a project can be built on it. It covers everything from the property line to the finished pad: clearing, demolition, excavation, grading, drainage, underground utilities, erosion control, and often the final paving and curbing. In plain terms, sitework turns raw dirt into a buildable, utility-ready site before a foundation is poured or a single piece of steel is set.

In the United States, the federal classification that best captures this trade is NAICS code 238910, Site Preparation Contractors. If you are trying to size the market, benchmark a firm, or search for competitors, that is the bucket to start with.

What sitework includes

Scope varies by project and by contract, but a typical sitework package contains most of the following:

• Clearing and grubbing: removing trees, brush, stumps and topsoil so crews can reach subgrade.
• Demolition: taking down existing structures, slabs and pavement, and handling the debris.
• Excavation and earthmoving: cutting, hauling, placing and compacting soil to reach design elevations.
• Grading: shaping the site to the civil drawings so water drains away from pads and roads.
• Storm and sanitary utilities: trenching and installing storm drains, sewer lines, water mains and dry utility conduits.
• Erosion and sediment control: silt fence, inlet protection and stabilized entrances required by the stormwater permit.
• Dewatering and soil stabilization: controlling groundwater and treating weak soils so pads will hold load.
• Access roads, building pads, paving and curbing: the finished surfaces that let the rest of the project mobilize.

Where sitework fits in the project timeline

Sitework is almost always the first package to break ground and, on large projects, it can start well before the structure itself is fully designed. Pads, stormwater systems and haul roads have to be in place before steel erectors, concrete crews and trade contractors can show up with equipment. That is why owners on data center, rail, wastewater and land development projects often release a separate early sitework package. Falling behind on sitework pushes every downstream trade, which is why the people running it carry outsized schedule risk.

Sitework vs. earthwork vs. heavy civil

These terms overlap and are often used loosely on job postings. Earthwork is the subset of sitework that deals strictly with moving and compacting soil. Sitework is broader and adds utilities, drainage, erosion control and paving. Heavy civil usually refers to public infrastructure such as highways, bridges and large-scale grading contracts. Many contractors do all three, and a superintendent who came up on highway earthwork can move into site development work, and vice versa, because the equipment, soils knowledge and production math are largely the same.

Who works in sitework

A sitework contractor is built around field leadership and estimating. The roles that show up most often in hiring conversations are:

• Sitework superintendents who run crews, equipment and subcontractors on the ground.
• Project managers who own the budget, schedule, submittals and owner relationship.
• Estimators who perform dirt takeoffs, price utilities and paving, and build production-based bids.
• Project engineers who track quantities, manage RFIs and coordinate testing and inspections.
• Foremen and skilled operators who run excavators, dozers, scrapers and pipe crews.

Employers screen for the ability to read civil plans, specifications and geotechnical reports, to perform accurate takeoffs, and to think in terms of production and unit cost rather than lump sums. A candidate who can look at a cut-and-fill balance and immediately spot where the haul plan falls apart is the profile hiring managers ask for first.

Why sitework risk shapes who gets hired

Sitework is where projects lose money quietly. Unmarked utility conflicts, groundwater that shows up higher than the borings suggested, excavation protection that was never priced, spoil that has to be hauled farther than planned, and grading delays caused by a wet season all eat margin before the building is even out of the ground. Because so much of the risk sits underground and depends on weather, contractors put a premium on superintendents and estimators who have already lived through those problems on comparable soils and comparable sites.

Where Amundson Group fits

Amundson Group is a Houston-headquartered, veteran-owned construction recruiting firm and an Inc. 5000 honoree in 2024 and 2025. Site development and land development, alongside heavy civil, data center, rail, tunnels and wastewater, are core sectors for us.

Frequently asked questions

What is the difference between sitework and earthwork?

Earthwork is one component of sitework. It refers specifically to cutting, hauling, placing and compacting soil to reach design grades. Sitework is the broader package that also includes clearing, demolition, storm and sanitary utilities, erosion control, dewatering, soil stabilization, and often paving and curbing. On many projects the same contractor performs both, and job titles such as sitework superintendent and earthwork superintendent are frequently used interchangeably. When reviewing a posting, look at the listed scope rather than the title to understand what the role actually covers.

What does a sitework superintendent do?

A sitework superintendent runs the day-to-day field operation on a site preparation project. That includes directing crews and equipment operators, sequencing clearing, grading, utility and paving work, coordinating with surveyors and testing labs, managing subcontractors such as pipe and paving crews, and keeping the job safe and on schedule. The best ones read civil plans and geotechnical reports fluently, track production against the estimate, and anticipate problems like groundwater, utility conflicts and weather delays before they stall downstream trades. It is a high-responsibility role because every other contractor on the project depends on sitework finishing on time.

What NAICS code covers sitework contractors?

In the United States, sitework contractors are generally classified under NAICS code 238910, Site Preparation Contractors. This category covers firms whose primary work is preparing land for construction, including excavation, grading, demolition, and installation of underground utilities and drainage. Some larger firms that also build highways and bridges may be classified under heavy and civil engineering construction codes instead. For recruiting, market research or competitor analysis, 238910 is the cleanest starting point when you want to identify companies whose core business is sitework rather than vertical construction.
