Sitework takeoff
Cut and fill, stripping, and utility trench quantities for Aurora's clay soils and flat-to-rolling subdivision pads.
CY · LF · TONWe produce line-item construction estimates and quantity takeoffs for Aurora, Illinois contractors, developers, and owners. Deliverables arrive in Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets so your bid review starts on solid numbers.
Aurora pricing is driven by Kane, DuPage, Will, and Kendall county labor rates, Chicago-area material logistics, expansive clay soils that push foundation costs, deep frost footings, and a permit market that ran 385 new residential units in 2025 with no multifamily share.
Aurora sits across four counties, and that single fact shapes how estimates get built here. A foundation package priced for a Kane County address can carry different labor and inspection assumptions than the same scope in the Will County portion. We price to the ZIP code, not to a regional average, using RSMeans data adjusted for the local market.
The 2025 permit year tells you where the volume is. Aurora issued 385 new privately-owned residential units, all single-family, with a permitted value of $177M and an average of $460,200 per unit. That is a custom and semi-custom market, not a tract or multifamily market, and the takeoffs reflect it. If you are bidding in this corridor, our Illinois construction estimating team covers Aurora alongside Naperville and Joliet, and we can turn most takeoffs in 24–48 hours.
For bidders. You need a defensible number before the bid date. We deliver division-by-division quantities with waste factors and marked-up plans so you can see exactly where the scope sits and where the gaps are.
For builders. You need to buy out trades and track changes. Our Excel takeoffs break out concrete, framing, roofing, and MEP quantities by area and unit so your purchase orders match the plans you are actually building.
For owners. You need a budget before design is finished. We price from schematic sets with assumptions flagged, so you can compare options and carry a contingency that reflects Aurora's soil and frost conditions.

385 new housing units in 2025 (-21.1% vs 2024).
385 single-family · 0 multifamily (0%).
Aurora issued 385 new residential units in 2025, down 21% from 488 in 2024, and every one of them was single-family. The permitted value was $177M, which works out to $460,200 per unit. For bidders, that means the work in this city is custom-home and infill scale, not multifamily podium or garden-style. Your estimate has to carry full sitework, individual utility runs, and one-off foundation layouts rather than repeated floor plates. The $460,200 average also tells you finishes and allowances are not builder-grade. If you are pricing a subdivision or a scattered-lot program, the state-level picture is worth reviewing on our Illinois construction estimating page before you set unit costs.
Aurora ranked 4th of 25 covered state cities by residential units in 2025, with 5.7% of the 6,710 total units across those cities. That is a real share of the state's residential pipeline, and it sits inside a Chicago metro that keeps producing logistics and data-center work alongside housing. The practical effect on estimating is that trade labor is shared between residential and industrial projects, and pricing moves when one side heats up. If your scope includes tilt-up, racking, or process systems, our industrial estimating services team prices that separately from the residential work. For pure commercial build-outs, start with commercial estimating services.
We cover the divisions that drive cost in Aurora's residential and commercial work, from dirt to trim.

Concrete, framing, and roofing crews in the Fox Valley need quantities they can buy from, not a lump sum. We break out formwork, rebar, anchor bolts, and square footage by area so your material order matches the plan set you are actually building.
Aurora permitted 385 single-family units in 2025 with zero multifamily, so your pipeline is custom and semi-custom infill. We price plan variations side by side so you can compare upgrade packages before you sign a purchase agreement.
You are comparing a Kane County parcel against a Will County one. We price sitework, foundations, and vertical scope to the ZIP code so your pro forma reflects the labor and material market where the dirt actually sits.
You need a cost check before the permit set is frozen. We price from schematic drawings with assumptions flagged, so you can revise the envelope or the structural system while changes are still cheap.
You are budgeting a warehouse expansion, a data-center fit-out, or a building addition along the I-88 corridor. We quantify the scope from your existing drawings and flag what a contractor will price as a change order later.
Aurora crosses Kane, DuPage, Will, and Kendall counties, and we price each portion to its own ZIP code. The communities below are the ones we see most often in bid invitations and plan sets.
The 2025 permit mix was 385 single-family units and no multifamily, so the bulk of our Aurora work is custom and semi-custom residential. The commercial side runs along the I-88 and Route 59 corridors.
Aurora's average permitted value was $460,200 per unit in 2025, which puts these in the custom and semi-custom range. We take off full scope from footing to finish, including the deep frost walls and basement waterproofing that Fox Valley soils require.
Watch for: Footing depth, damp-proofing, sump and drainage
Older Aurora lots near downtown often carry a teardown with an existing foundation that may or may not be reusable. We quantify demolition, haul-off, and new foundation work separately so you can compare keeping the basement against a full dig-out.
Watch for: Demolition, haul-off, reusing existing footings
Second-story additions and kitchen expansions are common in the established neighborhoods. We take off framing, roofing tie-ins, and MEP rough-in by area, and we flag where the existing service panel or HVAC capacity will not carry the new load.
Watch for: Roof tie-in, panel capacity, HVAC sizing
Route 59 and the I-88 corridor carry strip centers, restaurants, and service buildings. We price tenant fit-outs from the shell drawings, separating landlord work from tenant scope so the two budgets do not overlap or leave a gap.
Watch for: Landlord versus tenant split, grease and venting
The Chicago area logistics pipeline reaches into the Aurora market, and we see warehouse and light-industrial packages with slab-on-grade, tilt-up or PEMB walls, and heavy electrical service. We take off slab thickness, reinforcement, and dock equipment as separate line items.
Watch for: Slab thickness, reinforcement, dock equipment
Schools, churches, and municipal buildings in the Aurora area come with prevailing-wage and public-bid requirements. We organize those takeoffs by CSI division so your bid form lines up with the schedule of values the agency expects.
Watch for: Prevailing wage, bid form divisions, alternates
Aurora is not one market. The county line, the soil, the frost depth, and the labor pool all move the number, and an estimate that ignores any of them will be wrong in a predictable way.
Aurora extends into Kane, DuPage, Will, and Kendall counties, and permit review, inspection scheduling, and some fees differ by which side of the line your project sits on. We confirm the adopted code edition and the reviewing office with the local building department before pricing, because a plan approved in one county portion is not automatically approved in another. Stormwater and detention requirements also vary by jurisdiction, which changes sitework quantities.
Kane County · DuPage County · Will County · Kendall CountyNortheastern Illinois footings must bear below the local frost depth, which typically runs in the range of 42 to 48 inches in this part of the state. That drives concrete volume, formwork, and rebar for every foundation package. Confirm the adopted frost depth with the local building department, because it is set by the applicable code edition and can be amended locally. Basement walls, damp-proofing, and drain tile are separate line items, not allowances.
Frost depth · Footings · Basement walls · Drain tileMuch of the Fox Valley sits on heavy clay till that drains slowly and expands and contracts with moisture. We carry granular backfill, footing drains, and sometimes engineered fill as distinct quantities rather than burying them in a general excavation line. A geotechnical report changes the number more than any other single document on a residential job here. Without one, we flag the soil assumption in writing.
Clay till · Geotechnical report · Engineered fill · Footing drainsAurora sees real winters, which means temporary heat, freeze protection for concrete pours, and snow removal during the structural phase. Those costs belong in the general conditions section, not in a contingency nobody tracks. The IECC climate zone for this area also drives insulation R-values, window U-factors, and air-sealing details that show up in the envelope takeoff. Confirm the adopted energy code edition locally.
Temporary heat · Cold-weather concrete · IECC · Air sealingThe Chicago-area labor market is heavily unionized, and public work in Aurora carries prevailing-wage requirements. Even private residential bids feel the effect through the available crew mix and the going rate for concrete, carpentry, and mechanical trades. We price labor to the ZIP code using RSMeans data rather than a statewide average, because the difference between Aurora and a downstate market is significant on a per-unit basis.
Prevailing wage · Union trades · RSMeans · ZIP-code laborAurora sits inside the Chicago material supply chain, so most commodities arrive quickly, but engineered wood, switchgear, and specialty windows still carry lead times that affect the schedule and therefore the general conditions cost. We list long-lead items in the takeoff notes so your buyout happens in the right sequence. Sales tax treatment also differs between a residential improvement and a commercial new build, so confirm it with your accountant before you finalize the bid.
Engineered wood · Switchgear · Long-lead items · Sales taxAurora sits across four counties, and that split changes which adopted code edition and which inspection authority governs your scope. The trades below are where we see the largest quantity swings between a Kane County address and a Kendall or Will County one.
Most Aurora lots carry glacial till over clay, so stripping depth and unsuitable-soil over-excavation are the first quantities to pin down. We take off topsoil strip by square yard, then structural fill by compacted cubic yard using a shrink factor rather than a bank-volume guess. Underdrain, aggregate base and erosion control blanket run by linear foot along the same alignment. Detention and storm scope on the west side often ties into a regional basin, so the outfall pipe and riprap quantities belong in the takeoff even when the civil drawings show them on a separate sheet. Send the geotech report with the plans; it drives the over-excavation line far more than the plan notes do. See our sitework estimating services for the full division 31 breakdown.
Aurora's residential permit volume is almost entirely single-family, so floor joist and roof truss packages dominate the framing takeoff. We count studs from the wall elevation, not from a square-foot rule, and separate plates, headers, blocking and sheathing. Roof sheathing is measured on the slope, not the plan footprint, and the difference on a 9/12 pitch is not small. Wall and roof sheathing, house wrap and flashing tape each carry their own waste factor. On larger commercial shells, metal stud and joist framing gets taken off by linear foot with gauge called out per the structural drawings. Framing estimating services covers the division 06 items we carry.
MEP is where a plan-only takeoff most often misses scope, because fixture and equipment schedules lag the drawings. We take off plumbing by fixture count and by linear foot of pipe per size, with the domestic water, sanitary and vent systems separated. HVAC is taken off by tonnage, by linear foot of duct per size, and by diffuser count. Electrical is counted by device, by fixture type, and by linear foot of conduit and conductor per size. On industrial and data-center adjacent work in the Chicago corridor, the electrical distribution and cooling loads are the dominant cost. MEP estimating services covers the divisions 21 through 26 scope.
Footings and frost walls are set by the local frost depth, and the wall height that results is where footing takeoffs go wrong. We measure wall length by linear foot, apply the wall height from footing top to finished grade, and convert to cubic yards with a typical 5 to 8 percent waste allowance. Slab-on-grade goes in by square foot with thickened edges measured separately. Interior flatwork in a warehouse or shop building is usually the largest single concrete quantity on the job. Rebar is taken off by bar size and total length, then converted to tons, with lap and dowel waste carried as a percentage. Our concrete estimating services page covers division 03 in more detail.
Roofing quantities depend on whether you are pricing a tear-off or a recoat over an existing membrane. We measure the roof plan on slope, add for hips, ridges and valleys by linear foot, and carry drip edge, ice-and-water membrane and underlayment as separate lines rather than lumping them into the square count. In this climate, ice dam protection at eaves and in valleys is a real line item, and its extent follows the eave overhang. Commercial low-slope work is taken off by square with insulation thickness and cover board broken out. Flashing at curbs, pipe boots and wall terminations is counted by piece. Our roofing estimating services page shows the format.
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.

Dimensions below are illustrative. The method is what matters: perimeter first, then cross-section, then waste.
Assume a rectangular footprint of 44 ft by 28 ft with a 16 ft by 12 ft attached garage projecting from the front. The footing runs under the full perimeter of the conditioned house and the garage, and the garage front wall is open for the overhead door, so that segment is excluded.
Step 1 — footing length
| Segment | Calculation | Length (LF) |
|---|---|---|
| House perimeter | 2 x (44 + 28) | 144 |
| Garage, three sides | 16 + 12 + 16 | 44 |
| Garage door opening | deducted | -16 |
| Total | 172 |
Step 2 — cross-section. A typical continuous footing here runs 16 in. wide by 10 in. thick. Convert to feet: 1.333 ft x 0.833 ft = 1.111 sq ft.
Step 3 — volume. 172 LF x 1.111 sq ft = 191.1 CF. Divide by 27 CF per CY: 191.1 / 27 = 7.08 CY.
Step 4 — pier pads and interior bearing. Add four interior column pads at 24 in. x 24 in. x 12 in.: 4 x (2 x 2 x 1) = 16 CF = 0.59 CY.
Step 5 — subtotal. 7.08 + 0.59 = 7.67 CY.
Step 6 — waste and overpour. Footing trenches are rarely formed to exact dimension, so we carry a typical 5 to 8 percent. At 7 percent: 7.67 x 1.07 = 8.21 CY, rounded to 8.25 CY ordered.
Step 7 — rebar. Two continuous #4 bars plus #4 dowels at 4 ft o.c. gives roughly 344 LF of continuous bar plus 43 dowels at 2.5 ft each, or 108 LF. Total 452 LF. #4 bar weighs 0.668 lb per LF, so 452 x 0.668 = 302 lb, plus 10 percent lap and waste = 332 lb, or 0.17 tons.
Two things change this number fast. If the geotech report calls for over-excavation and a deeper footing, the cross-section grows and the volume follows. If the plan moves to a stepped footing on a sloped lot, you add vertical steps and the length grows. Both need to be resolved before the number is issued. Send your plans through our get an estimate page and we will return the same breakdown by CSI division.
A single Aurora address falls into Kane, DuPage, Will or Kendall County depending on the parcel, and each has its own permit office, review sequence and adopted code edition. That changes plan review fees, inspection scheduling and sometimes the energy code path. It does not change how we measure quantities, but it does change the general conditions and permit line items we carry. Confirm the adopted edition and the reviewing authority with the local building department before you finalize your bid.
We do not assume one. We read the footing detail on your drawings and use the depth shown, then flag it if the detail is shallower than what the local building department enforces. The reason is that frost wall height drives concrete volume directly, and a 6-inch difference over a long perimeter is a real quantity. If your drawings do not state a depth, we ask before we price, because guessing here is how footing bids go sideways.
The measurement discipline is the same, but the line item structure differs. Residential takeoffs follow a shorter division list and lean on unit-count items like fixtures and trusses. Commercial and industrial takeoffs carry full CSI division breakdowns, separate general conditions, and often a division 26 and 23 scope large enough to price on its own. We issue both in Excel and PDF, organized by division with marked-up plan sets so you can trace every quantity back to the sheet.
Most projects come back in 24 to 48 hours, and rush turnaround is available when a bid date is close. The main variable is drawing completeness. A full architectural, structural and MEP set with schedules goes faster than a partial set where we have to request missing sheets. If your set is incomplete, tell us up front and we will tell you which sheets we need before we start rather than issuing a number with holes in it.
Send the complete plan set, the specification book, the geotechnical report if you have one, and any addenda. We also want the project address so we can apply ZIP-code-adjusted material and labor pricing rather than a national average. If you have a bid form or a trade breakdown you are working to, send that too, because matching your format saves you a reformatting step. Anything you can tell us about the site, access or phasing helps as well.
Yes. We cover the surrounding suburbs and the wider Chicago area, and we keep the pricing basis tied to the project ZIP code rather than the city name. A framing package in Naperville and one in Joliet will measure the same if the plans match, but the labor and material rates can differ. We also run takeoffs for Rockford and Chicago projects. The state-level overview is on our Illinois construction estimating page.
The figures come from the U.S. Census Bureau Building Permits Survey for 2025, and they count new privately-owned residential units permitted by the city itself. That means the 385 units and the $177M permitted value cover residential only. They exclude commercial, industrial and institutional permits, and they exclude renovations. If your project is a warehouse, a retail shell or a tenant fit-out, the residential permit trend here tells you nothing about your scope or your competition.
It changes the competitive picture more than the unit rates. Fewer starts can mean more bidders chasing the same work, and it can also mean subcontractors are hungrier on labor. Material pricing follows national and regional supply more than local permit counts. What we do is apply ZIP-code-adjusted rates to your quantities so the number reflects this market, and we note where a line item is more sensitive to labor availability than to material cost.
Yes. The Chicago area has a steady logistics and data-center pipeline, and those projects are electrical and mechanical heavy. The takeoff emphasis shifts to division 26 distribution, switchgear, conduit and conductor by size, plus division 23 cooling and air handling. Sitework and slab quantities are large but comparatively simple. If you are bidding a shell or a fit-out in that market, send the electrical and mechanical drawings along with the architectural set, because a plan-only takeoff will miss most of the cost.
Excel and PDF, organized by CSI MasterFormat division, with marked-up plan sets so every quantity ties to a location on the drawing. We use Bluebeam Revu for markup, PlanSwift for quantity extraction, and RSMeans data as a pricing reference, adjusted to the project ZIP code. If you work in a different structure, tell us and we will match your column layout. The goal is a file your estimator can open and use, not a report that needs re-keying.
Send the plan set, specs and project address, and we will return a division-organized takeoff in 24 to 48 hours.
