Sitework and excavation
Mass grading, basement excavation, backfill and haul-off for tight Naperville infill lots.
CY · SF · TONScope Precision Estimate prepares quantity takeoffs and cost estimates for Naperville contractors, developers and owners. We price by ZIP code, organize everything by CSI MasterFormat division, and return most estimates in 24–48 hours.
Naperville pricing is driven by DuPage County labor rates, clay-heavy soils that push foundation and dewatering costs, IECC climate zone 5 envelope requirements, mature-lot demolition and haul-off, and City of Naperville permit review. These factors move unit costs more than the national averages many bidders carry.
Naperville sits in DuPage County, about 30 miles west of Chicago, and it is the third-largest city in Illinois by size. Its permit mix skews almost entirely single-family: of 228 new privately-owned residential units permitted in 2025, 224 were single-family and only 4 were multifamily. That means most takeoffs here are detached homes, additions, teardown rebuilds and small commercial fit-outs, not tower work.
We build estimates from the plans, not from square-foot rules of thumb. Wall, floor and roof assemblies are measured; concrete is broken into footings, foundation walls, slab and flatwork; MEP is counted by fixture and device. Material and labor lines are adjusted to Naperville ZIP codes so your bid reflects what local suppliers and crews actually charge. If you bid across the region, our Illinois construction estimating page covers the state, and we also work the surrounding markets in Aurora and Chicago.
For bidders. You need a defensible number before the deadline. Send plans and specs and we return a division-organized takeoff with quantities, waste factors and marked-up drawings you can check line by line.
For builders. You are buying out trades and tracking change orders. We give you quantities by CSI division so you can compare subcontractor quotes against the same scope and spot what a bid left out.
For owners. You are testing a budget before design is finished. We price what is drawn, flag what is missing, and separate hard cost from allowances so your pro forma holds up.

228 new housing units in 2025 (-38.2% vs 2024).
224 single-family · 4 multifamily (2%).
Naperville issued 228 new privately-owned residential units in 2025, down 38% from 369 in 2024. Single-family accounted for 224 of those units; multifamily was 4 units, or 2% of the total. Permitted value was $114M, an average of $498,000 per unit. For bidders, the takeaway is that Naperville work is custom-home and infill scale, where per-unit costs swing with site conditions, finished square footage and envelope detail rather than with repetition. Naperville ranked 6th of 25 covered Illinois cities by units and accounted for 3.4% of the 6,710 units permitted statewide. That concentration of detached construction means foundation, framing and roofing quantities carry the estimate, and a missed footing or roof-plane count is expensive. Our residential estimating services are built around that scope.
The Chicago area remains a major commercial and industrial hub with a strong logistics and data-center pipeline, and Naperville sits inside that labor and supply chain. Local commercial estimating usually means office and retail fit-out along the I-88 and Ogden Avenue corridors, warehouse and light-industrial shells, and institutional work for school and park districts. Those projects bring different cost drivers: structural steel and joist pricing, rooftop mechanical units, electrical service upgrades, and NFPA 13 sprinkler scope. Multifamily is a small share of Naperville permits, so when a larger project does come through, verify whether the local jurisdiction or a surrounding one has adopted a newer code edition. Our commercial estimating services and MEP estimating services cover that scope.
We price the scopes that actually appear on Naperville plans, from teardown sites to tenant fit-outs.

Naperville is not a single market. A bid on a downtown infill lot and one in a western subdivision carry different soil, access, code and labor assumptions, and the estimate has to show that.
Naperville enforces the adopted Illinois building code family along with local amendments for stormwater, tree preservation and lot grading. Plan review comments routinely add hold-downs, bracing and energy details after the first submittal. Confirm the adopted code edition and any local amendments with the Naperville building department before you lock the estimate, because a revision cycle can move your bid date.
IBC · IRC · IECC · Naperville building departmentDuPage and Will county soils range from silty clay to glacial till, and some western subdivisions sit on fill that was placed when the fields were graded. That changes footing width, granular backfill and sometimes piering. We carry footing and foundation wall quantities separately so a geotech recommendation can be applied without redoing the whole takeoff.
glacial till · silty clay · geotechnical report · granular backfillFrost depth in northern Illinois drives footing elevations and foundation wall height, and it also sets the season for flatwork, masonry and exterior finishes. A winter start adds temporary heat, hoarding and cold-weather concrete protection. We note these as separate line items so you can see the cost of schedule, not bury it in general conditions.
frost depth · cold-weather concrete · temporary heat · hoardingCrews working Naperville are drawn from the Chicago metro labor pool, and wage rates for carpenters, electricians and operating engineers reflect that market. Public and institutional work may carry prevailing wage requirements that change the labor column entirely. Our pricing uses ZIP-code-adjusted material and labor data, and we identify which scopes are wage-sensitive.
Chicago metro labor · prevailing wage · RSMeans data · ZIP-code adjustmentNaperville's stormwater and grading rules can require detention, rain gardens or restrictive lot coverage on infill lots. On tight downtown parcels, staging and crane access are limited, which adds hand excavation and material handling. We quantify earthwork by cut and fill and flag any scope that depends on a grading permit.
detention · lot coverage · cut and fill · grading permitMost Naperville suppliers ship out of the Chicago metro, so haul distances are short but lead times on windows, trusses and switchgear are not. Long-lead items affect both the schedule and escalation. We list them with quantities so your buyout can lock pricing early instead of carrying a contingency you cannot explain.
trusses · windows · switchgear · escalationNaperville sits in DuPage and Will counties, where deep frost, clay till and a mature suburban street grid shape what a takeoff must carry. Here is how that plays out in the divisions we price most often.
Most Naperville residential work starts with stripping 6 to 8 inches of topsoil, then mass excavation in stiff clay till. Frost depth in this part of Illinois runs roughly 42 inches, so water services, sanitary laterals and footing bottoms sit below that line. A takeoff that stops at building pad volume will miss the export of unsuitable clay, haul-off truck counts, and the import of granular backfill. Winter bids need rock excavation and dewatering lines even when the geotech report is clean. On tight infill lots near the downtown core, you also carry street-sweeping and dust control. Start with our sitework estimating services when a project includes grading, utilities and paving.
Wood-frame residential is the dominant Naperville type, with engineered floor systems, roof trusses and 2x6 exterior walls. A framing takeoff must count studs at 16 inches on center plus plates, headers, jack and king studs, and blocking at fixtures. Roof trusses come with a truss package from the supplier, but you still quantify bearing, hangers and bracing. Sheathing is counted by sheet, and you add typical waste of 5 to 10 percent on lumber and 10 percent on sheathing. Look for the plan note that changes wall height or adds a tray ceiling, because that shifts stud length and plate counts. Framing estimating services will pull these quantities into a single package.
Mechanical, electrical and plumbing quantities are driven by fixture counts and room-by-room layouts, so a takeoff should be built from the plan rather than a square-foot allowance. Count supply and return registers, bath fans, water closets, lavatories, tubs and shower valves, then trace pipe and duct runs. Electrical needs device counts, panel schedules, and home-run lengths. Interior finishes use room-by-room schedules for drywall, tape, texture, paint, trim and flooring. Basements and garages change the numbers quickly. Our MEP estimating services and residential estimating services packages are built to match this level of detail.
Foundations here are typically cast-in-place strip and spread footings bearing below frost, with 4-inch slab-on-grade over a vapor barrier and capillary break. The takeoff has to separate footing concrete from wall concrete because mix designs and formwork differ. Add anchor bolt templates, keyways, dowels at construction joints, and a minimum 10 mil underslab vapor retarder under slab. Basement walls in this area often carry exterior dampproofing and drainage board against the clay. If the structural drawings show a thickened-edge slab or pier system, quantify pier depth per the geotech, not a default. Our foundation estimating services and concrete estimating services cover these divisions line by line.
Asphalt shingle roofs dominate, with ice and water shield required at eaves and valleys because of freeze-thaw cycles. Underlayment, drip edge, ridge vent, step flashing and pipe boots all need their own line. On the wall side, count house wrap, flashing at windows and doors, and the siding or masonry veneer separately. Brick veneer over wood frame requires a drainage plane, weep holes and lintels, so the takeoff must carry those items even when the drawings only show a wall section. Roofing estimating services handle the roofing scope; envelope items usually sit in the same package so nothing falls between trades.
Quick check for a single element. For a full drawing set, send the plans and we measure everything, including the items calculators miss.
Typical waste: 3–5% for slabs, 5–10% for footings and walls. Truck count assumes 10 CY loads; confirm load size with your ready-mix supplier.

This example uses illustrative dimensions for a two-story house with a full basement on a typical Naperville lot. The goal is to show how a footing takeoff is built, not to quote a real project. Confirm actual sizes with the structural drawings and the geotech report.
Assume continuous strip footings 16 inches wide by 10 inches thick under exterior foundation walls, with an interior bearing line of the same size. The exterior perimeter measures 40 ft by 28 ft, and the interior bearing wall runs 40 ft. Footing length is the perimeter plus the interior run.
| Step | Calculation | Result |
|---|---|---|
| Exterior footing length | 2 x (40 + 28) | 136 LF |
| Interior footing length | 40 | 40 LF |
| Total length | 136 + 40 | 176 LF |
| Cross-section area | (16/12) x (10/12) | 1.111 SF |
| Net volume | 176 x 1.111 | 195.6 CF |
| Convert to cubic yards | 195.6 / 27 | 7.24 CY |
| Waste and spillage at 5% | 7.24 x 1.05 | 7.60 CY |
| Order quantity | round up to nearest 0.5 CY | 8.0 CY |
Two adjustments matter in this market. First, footing bottoms sit below the local frost depth, so if the geotech pushes the bearing elevation deeper, add depth times the same cross-section to the net volume. Second, interior column pads and any stepped footings are separate line items; count each pad as length times width times thickness and add them before applying waste. Rebar is taken off separately by bar size and lap, not as a percentage of concrete. If you want this level of detail on your own drawings, send the set through our get an estimate page and we will return quantities by CSI division in Excel and PDF.
The figures come from the U.S. Census Bureau Building Permits Survey for 2025, which counts new privately-owned residential units permitted by the city itself. In 2025 Naperville issued 228 units, down from 369 in 2024, a change of about -38 percent. Of those, 224 were single-family and 4 were multifamily, so multifamily was about 2 percent of the total. The permitted value was $114M, averaging $498,000 per unit. The survey covers residential only, so commercial and industrial permits are not included. Confirm current numbers with the city before using them in a pro forma.
The takeoff method is the same, but the pricing inputs differ. We use ZIP-code-adjusted material and labor pricing, so a Naperville address and a Joliet address can carry different rates for the same line item. Labor agreements, material yards and haul distances change the numbers. If your project crosses a county line, tell us which address governs the pricing. We also cover nearby markets such as Aurora and Joliet with the same format so you can compare bids side by side.
Send the architectural, structural, civil and MEP drawings in PDF, plus any specifications, geotech report and addenda. If you have a preferred unit price source or a past estimate to match, include it. We return quantities organized by CSI MasterFormat division in Excel and PDF, with marked-up plan sets showing what was measured. Most projects turn around in 24 to 48 hours, and rush service is available when a bid date is close.
Yes. Foundation-only and concrete-only packages are common because those scopes carry the most risk on residential and light commercial work. We quantify excavation, backfill, footings, walls, slab, vapor retarder, rebar and formwork as separate lines. If the geotech report calls for over-excavation or a granular replacement layer, we add it as its own item so you can see the cost. That keeps the foundation bid from absorbing a sitework cost that belongs in another division.
We add line items for temporary heat, insulated blankets, cold-weather concrete admixtures and extended curing when the schedule runs through the heating season. Masonry and concrete work in particular need protection below freezing. These items are easy to leave out of a summer-priced estimate and then absorb in the field. If you tell us the planned construction window, we will flag the divisions where winter protection changes the quantity or the unit cost. Confirm local inspection requirements with the Naperville building department.
We estimate both. The Chicago area remains a major commercial and industrial hub with a strong logistics and data-center pipeline, and that work shows up in Naperville and the surrounding corridor. Commercial packages typically need Division 03, 05, 08, 09, 22, 23, 26 and 31 quantities, plus a separate site package. Industrial and data-center shells add process piping, heavy electrical and specialty foundations. Send the drawings and we will tell you which divisions we can carry and which need a specialty trade partner.
Accuracy depends on the quality of the drawings and how completely the scope is documented. We measure from the PDF in Bluebeam Revu and PlanSwift, then price with RSMeans data adjusted to the project ZIP code. Where the drawings are silent, we note the assumption rather than guessing silently. You get a marked-up set so you can see exactly what was measured. Always confirm dimensions and details against the latest addenda before you submit a bid.
Deliverables come in Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets. The Excel workbook is built so you can adjust quantities, unit costs and waste factors without rebuilding the sheet. Many clients drop our quantities straight into their own estimating software. If you need a specific column layout or a summary by trade, tell us at kickoff and we will match it.
Yes. We cover Chicago, Aurora, Joliet, Rockford and Springfield, plus the broader Illinois market. Pricing is adjusted by ZIP code, so a project in Aurora or Joliet is priced with the rates that apply there rather than Naperville rates. If you have multiple projects across the region, we can deliver them in the same format so you can compare them directly. See the Illinois construction estimating page for the full list of areas we serve.
Yes. Send the existing estimate along with the drawings, and we will check quantities division by division and flag missing scope. Common findings include missing frost-depth excavation, omitted vapor retarder, and allowances that do not match the plan. We return a comparison showing our quantities against yours, with notes on where the difference comes from. That is often faster than a full takeoff when a bid date is close.
Send your drawings and specifications and we will return a division-by-division takeoff in Excel and PDF, usually within 24 to 48 hours.
