Sitework estimates that start with the dirt,
not with a guess.
Sitework sets the financial tone for everything that follows. Get the earthwork wrong and you're fighting an uphill battle before the first footing is poured. Get the utility layout wrong and you're negotiating change orders before the building is framed. Sitework has more variables than most trades soil conditions, existing topography, utility depths, material haul distances and a lot of those variables don't fully reveal themselves until a machine hits the ground. The best protection against that is a careful estimate built from the actual civil drawings, not from a cost-per-acre rule of thumb that ignores everything that makes your site different from every other site. That's what we build.
What Is Sitework Estimating?
Sitework estimating is the process of quantifying and pricing everything outside the building footprint: clearing, earthwork cut and fill, grading, storm, sanitary and water utilities by size and depth, paving, curbs, site concrete, erosion control and the equipment and labor to build them. A sitework takeoff is the quantity part of that work; the estimate adds pricing.
Remarkable Estimating Services, LLC, based in Hawthorne, California, prepares sitework takeoffs and cost estimates for site contractors, general contractors, developers and owners in all 50 states. We work remotely from your civil drawings, grading and utility plans, geotechnical report and specifications and deliver an itemized Excel or PDF estimate, typically within 48–72 hours. We are an estimating firm: we do not perform site, earthwork or paving work.
Excavation for structures is covered in excavation estimating; related scopes in landscape, concrete and plumbing estimating. For the whole project, see our full-project cost estimating and quantity takeoffs.
Why Sitework Estimates Are the Riskiest Numbers on Any Bid
Sitework carries more inherent uncertainty than almost any other construction scope and that uncertainty gets amplified when the estimate isn't built carefully. Unlike a building trade where the quantities are defined by the drawings, sitework quantities are defined by the existing conditions on the ground. Topography, soil classification, existing utility locations, groundwater levels, and material haul distances all directly affect cost in ways that don't always show up clearly on the civil drawings.
The earthwork cut-fill balance is where most sitework estimates go wrong first. A grading plan shows proposed contours. Calculating the actual cut and fill volumes requires reading the existing and proposed grades carefully, applying the right calculation method for the site geometry, and factoring in soil swell and compaction ratios that are specific to the soil type on that site. Using a generic swell factor when the geotech report indicates a different soil classification will give you a cubic yard count that's wrong before you've started pricing equipment or haul.
Underground site utilities are the second major problem area. Water, sewer, storm drain, gas, and electrical conduit runs that look straightforward on a plan view often involve trench depths, bedding requirements, and separation distances that add material and labor that isn't visible from the horizontal plan. A 6-inch sewer main at 12 feet of depth requires a completely different trench width, shoring consideration, and pipe bedding scope than the same pipe at 4 feet of depth. The cost difference is real, and it only shows up when someone takes the time to read the utility profiles and invert elevations on the civil drawings.
Pavement is the third area where estimates fall short. Asphalt section design varies by traffic loading a pedestrian path section and a heavy truck court section at the same location have completely different base course depths and surface thicknesses. Pricing all pavement at a single rate per square yard because it's all "asphalt" misses the cost differentiation that the civil pavement section schedule explicitly calls out.
We read the civil drawings carefully grading plans, utility plans, profiles, pavement sections, and the geotech report where available and build every quantity from what the drawings actually show, not from what a rule of thumb suggests for a generic site of that size.
Sitework is the one scope on a project where the contractor is most exposed to conditions they didn't fully anticipate. A careful estimate doesn't eliminate that exposure, but it makes sure you weren't also surprised by your own numbers.

How Our Sitework Estimating Process Works
From your civil engineering drawings and geotech report to a finished, scope-by-scope sitework estimate ready for bid submission here's exactly how we work through a sitework takeoff.
You send us your civil drawings, specifications, and geotech report
Grading and drainage plans, utility plans, utility profiles, pavement section schedule, erosion control plan, civil details, and Division 31 and 32 specifications. The geotech report is particularly valuable it gives us soil classification, bearing capacity, swell and shrink factors, and groundwater conditions that directly affect earthwork quantities and unit costs. If a geotech report isn't available, we use conservative soil assumptions and document them clearly. If anything is missing or unclear on the civil drawings, we flag it before we start rather than assuming our way through it.
PDF, CAD, or Bluebeam all formats accepted
We separate every sitework scope before measuring anything
Earthwork, site utilities, paving, concrete, erosion control, and site amenities all have different subcontractor scopes, different equipment requirements, and different cost profiles. Combining them into a single "sitework" line item creates a number that tells you nothing about where the cost is concentrated or where the risk is highest. We identify and separate every sitework scope at the start and estimate each one independently so the breakdown is useful for leveling sub bids and understanding where your exposure is on a site with unusual conditions.
Every scope separated never blended
Earthwork volumes calculated from actual grades with soil factors applied
Cut and fill volumes get calculated from the grading plan using average-end-area or grid-cell methods depending on site geometry and the level of design detail available. Swell factors for cut material and compaction factors for fill material get applied based on the soil classification from the geotech report not from a generic average that may not reflect what's actually in the ground. Where the geotech indicates difficult soil conditions or high groundwater, we note it as a risk item with a specific cost implication rather than burying it in a contingency.
Actual grades · Geotech-based soil factors
Utilities measured with profile depths paving by section design
Underground utility pipe runs get measured from the plan with depth taken from the utility profiles and invert schedules not assumed from a standard burial depth. Trench width, bedding volume, and shoring requirements get calculated based on actual pipe size and depth. Pavement quantities get measured from the civil plan with the pavement section schedule determining base course and surface thickness for each area heavy truck courts, standard drive lanes, pedestrian paths, and fire lanes all get measured separately and priced to their actual section design.
Profile-based utility depths · Section-based pavement
Regional pricing and equipment rates, missed-item review, then clean delivery
Material costs for aggregate base, pipe, concrete, and asphalt vary significantly by region and by local supplier availability. Equipment rates for earthwork operations reflect local rental and owner-operator costs for your market. Before the estimate leaves our desk, we check for the sitework items most commonly missed: dewatering allowances where the geotech indicates groundwater, erosion control inspection and maintenance, utility testing and inspection, and permit and connection fees. Delivery is a clean Excel or PDF organized by scope earthwork, utilities, paving, concrete, and site improvements with a complete scope notes and exclusions sheet.

Types of Sitework Projects We Estimate
From a single residential lot preparation to a full site development package for a large industrial campus sitework estimate complexity is determined by topographic relief, utility scope, and pavement area, not just by project type. Our process handles every scale.
Residential Sitework Estimating
Single-family lots, subdivisions, townhome communities, and apartment complexes residential sitework covers lot clearing, rough and finish grading, underground utilities to each unit, driveway and parking area paving, sidewalks, and erosion control. Subdivision sitework is particularly scope-intensive because the utility runs are long, the grading has to work across multiple lots simultaneously, and the phasing plan affects how earthwork quantities get sequenced. We give site contractors and developers a complete scope-by-scope breakdown with quantities that trace back to the civil drawings.
Commercial Sitework Estimating
Office developments, retail centers, schools, hospitals, hotels, and mixed-use projects commercial sitework typically involves complex utility coordination, significant pavement scope, structured stormwater management, and tight site constraints that affect equipment access and material staging. The civil drawings on commercial projects are usually more complete and more detailed than on residential work, which allows for tighter quantity calculations but also means there's less room to hide a scope gap behind a contingency. We read the full civil package and price every scope item from what the drawings actually show.
Industrial Sitework Estimating
Warehouses, manufacturing facilities, distribution centers, and industrial parks industrial sitework involves large grading areas, heavy-duty pavement sections designed for truck and forklift loading, substantial utility infrastructure, and often significant earthwork volumes because industrial sites are frequently developed on raw or previously undeveloped land. The pavement scope alone on a large logistics facility can represent a significant portion of the total project cost. We measure every pavement area by section design, calculate earthwork from actual grading plans, and price utilities from profiles and invert schedules.
Why Site Contractors Choose Remarkable Estimating
Here's what working with us on a sitework scope actually looks like in practice.
Earthwork Volumes From Actual Grades, Not From Acreage Rules
A cost-per-acre earthwork estimate tells you nothing about the relief on your specific site, the cut-fill balance, or whether the material on that site is usable fill or needs to be exported. We calculate cut and fill volumes from the actual grading plan using the existing and proposed contours with soil swell and compaction factors from the geotech report applied per soil classification. The result is a quantity that reflects your specific site, not a generic assumption about what an acre of grading costs.
Utility Depths From Profiles, Not From Assumed Cover
Standard minimum cover depth is a code requirement. Actual installed depth on a specific site is determined by the utility profile and invert schedule on the civil drawings and it's often deeper than the minimum because of site topography, crossing utilities, or frost depth requirements. We read the utility profiles, pull invert elevations, and calculate trench depth, width, and bedding based on what the drawings actually show for each pipe run.
Pavement Measured by Section Design, Not a Blanket Rate
Civil drawings include a pavement section schedule that defines base course depth and surface thickness for each pavement area based on traffic loading. Heavy truck courts, standard parking areas, drive lanes, fire access routes, and pedestrian paths all have different section designs and different material costs per square yard. We measure every pavement area by its designated section type and price each one separately. Using a single blended rate across all pavement types is one of the most common ways sitework estimates lose money on large commercial sites.
Every Sitework Scope Priced Separately, Organized for Buyout
Earthwork contractors, utility contractors, paving contractors, and concrete subcontractors all bid separately. A sitework estimate that rolls all of these into one number is unusable for bid leveling and tells you nothing about where your cost exposure is concentrated. Our estimates break out every sitework scope with its own quantities and costs so you can compare each scope to sub bids independently and identify where a number looks right or wrong before you're committed.
Risk Items Flagged, Not Hidden in Contingency
Dewatering requirements, soft subgrade conditions, unknown utility conflicts, and rock excavation possibilities are risk items that belong in a sitework estimate as explicitly identified line items not buried inside a general contingency percentage that obscures what the risk actually is. When the geotech report indicates a condition that affects cost, we call it out with a specific allowance so you know what you're carrying and why. That's more useful than a flat contingency that nobody can explain.
48–72 Hour Turnaround Flat Project Pricing
Sitework bids often carry short windows because civil drawings are sometimes issued late in the bid process. Standard turnaround is 48–72 hours from receiving a complete civil drawing set. Rush delivery is available for tighter timelines just let us know upfront. Pricing is quoted based on project scope and may be provided as a flat project fee or hourly rate. Flat project fees are agreed upfront. No retainers, no revision fees for reasonable clarification questions. Your drawings and site data stay completely confidential.
