Sitework and excavation
Over-excavation, structural fill, haul-off and utility trenching measured for tight infill lots in Lakewood.
CY · LF · TONWe produce CSI MasterFormat takeoffs and estimates for Lakewood contractors, developers and owners, priced with ZIP-code-adjusted material and labor data. Most projects return in 24–48 hours as Excel and PDF with marked-up plan sets.
Lakewood pricing turns on Front Range clay soils and expansive subgrade, Jefferson County permitting, high-wind and hail exposure on roofing and exterior envelopes, Denver-metro labor rates, and infill logistics where tight lots drive excavation and haul-off costs. Each of these shifts unit prices away from generic state averages.
Lakewood sits on the west side of the Denver metro, and its work is mostly infill: tear-downs and rebuilds, additions, small commercial tenant improvements along the West Colfax and Wadsworth corridors, and residential remodels. That mix puts pressure on sitework and concrete quantities, because you are digging in expansive Front Range clay on lots that were platted decades ago. We take off the excavation, over-excavation, and import or removal separately so your bid does not carry an allowance you cannot defend.
Our takeoffs are organized by CSI MasterFormat division and priced with ZIP-code-adjusted material and labor data from RSMeans, delivered in Excel and PDF with marked-up plan sets. If your project is larger or spans trades, start with our Colorado construction estimating overview, or go straight to sitework and concrete scopes where Lakewood jobs usually gain or lose margin. For residential work, see residential estimating; for commercial interiors and shell work, see commercial estimating.
For bidders. You need quantities you can defend at bid day. We return line-item takeoffs by division with waste factors stated, so you can adjust your markup instead of guessing at the scope.
For builders. You need buyout and change-order support. We break out excavation, concrete, framing and MEP so you can compare subcontractor quotes against the same quantity basis.
For owners. You need a budget before design is finished. We estimate from concept plans and flag the line items most likely to move as drawings develop.

54 new housing units in 2025 (-70.8% vs 2024).
54 single-family · 0 multifamily (0%).
Lakewood issued 54 new privately-owned residential units in 2025, down from 185 in 2024 — a 71% decline — with all 54 single-family and no multifamily units permitted. Permitted value was $24M, averaging $442,700 per unit. For bidders, that means fewer new-build packages chasing the same crews, and more competition on remodels, additions and tenant improvements. In that environment, an estimate that overstates excavation or concrete quantities loses the job, and one that understates them loses money. Ranked 20 of 21 among the covered state cities by units, Lakewood is not a volume market right now; it is a precision market. Compare the wider Front Range picture on our Colorado estimating page or see how nearby Arvada and Westminster are tracking.
Lakewood's housing stock is largely built out, so the work skews to additions, structural remodels, foundation repairs and small commercial fit-outs rather than greenfield subdivision. Those projects carry scope that is easy to miss: underpinning and shoring on additions, temporary shoring at removed bearing walls, and utility relocations on older lots. Expansive clay soils across Jefferson County mean post-tension or stiffened slab designs, deeper pier counts, and over-excavation with imported structural fill — all of which belong in the estimate as measured quantities, not allowances. Roofing and exterior scopes also carry Front Range hail and wind exposure, so we take off replacement-cost line items rather than patch assumptions. For multifamily and attached product, see multi-family estimating.

Expansive clay on old Lakewood lots means over-excavation, import and removal quantities decide the job. We separate those lines so your bid holds when the geotech report arrives.
Tear-downs, second-story additions and basement finishes on 1950s–1970s housing stock rarely match original drawings. We take off from the existing conditions you actually measured.
Small commercial and mixed-use infill along West Colfax needs a budget before design is complete. We estimate from concept plans and flag the line items most likely to move.
You need cost feedback while drawings are still editable. Our division-level takeoffs show which assemblies are driving cost so you can adjust details before the permit set is issued.
Ongoing repairs and tenant build-outs on older Lakewood buildings need scopes priced quickly. We turn unit-price takeoffs for roofing, MEP and concrete repairs in 24–48 hours.
We estimate projects across Lakewood and the west and north Denver metro, from Belmar and the West Colfax corridor out to the Jefferson County foothills edge.
Lakewood permitted 54 new privately-owned residential units in 2025, all single-family, so the local mix leans toward infill houses, additions and remodels rather than multifamily towers.
Tear-down and rebuild projects on platted lots, often with a walkout basement and a detached or attached garage. We take off excavation, foundation, framing and envelope from the permit set.
Watch for: Over-excavation depth, import/export haul, and retaining walls at the rear yard.
Second-story additions, kitchen and bath gut renovations, and basement finishes on 1950s–1970s housing. Existing framing and MEP routes rarely match the drawings, so we price from field-verified dimensions.
Watch for: Tie-in framing, temporary weather protection, and re-routing of existing MEP.
Tenant improvements, shell buildings and mixed-use infill along West Colfax and Wadsworth. Scopes are usually interior fit-out with a small structural package and storefront glazing.
Watch for: Storefront systems, ADA restroom upgrades, and fire sprinkler modifications.
Small warehouse, contractor shop and service buildings near the industrial pockets along the west metro. We take off slab-on-grade, pre-engineered or tilt-up structure, and utility service.
Watch for: Slab thickness and reinforcement, dock or grade-beam details, and service capacity.
Small townhome and duplex projects are common on redeveloped parcels even when citywide multifamily permitting is quiet. We break out unit-by-unit quantities and shared sitework.
Watch for: Shared utility trenches, fire separation assemblies, and per-unit finish schedules.
Church additions, school district projects and municipal facility work in and around Lakewood. These scopes carry prevailing-wage and bonding requirements that change the labor and overhead lines.
Watch for: Prevailing wage, certified payroll, and bonding and insurance line items.
Lakewood estimates move on the same handful of drivers: Jefferson County soil and drainage, Front Range weather, permit review timing, and the cost of working on tight infill lots.
Lakewood reviews building permits through its own community development department, and Jefferson County handles unincorporated parcels nearby. Review comments on drainage, grading and right-of-way often arrive after bid day, so we carry a line for plan-revision rework. Confirm the adopted code edition, permit fees and review timelines with the city or county building department before you lock your bid.
City of Lakewood Community Development · Jefferson County · IBC/IRC adopted editionFront Range clay soils shrink and swell with moisture, and older Lakewood lots often have undocumented fill. Geotechnical reports typically drive over-excavation, engineered fill, and deeper pier or caisson foundations. We take off over-excavation by cubic yard, import and export separately, and price the foundation system the geotech actually specifies rather than a default spread footing.
Geotechnical report · Over-excavation · Drilled piers · Foundation Estimating ServicesLakewood sits at the base of the foothills, where snow loads, wind exposure and freeze depth drive roof structure, frost-depth footings and exterior detailing. Roof snow-load zones and freeze-protection depths come from the adopted code and local amendments. We price insulation, ice barrier and footing depth to the code the jurisdiction has adopted, and note where a foothills-edge site may need a higher snow load.
IECC · Frost depth · Roof snow load · NFPA 13Denver metro labor rates are set by the Front Range market, and small infill jobs compete for the same concrete, framing and finish crews as larger projects. Short-duration remodels often carry a premium because crews cannot stay productive on a tight site. We price labor from ZIP-code-adjusted RSMeans data and note where a scope is likely to draw a minimum-charge or mobilization premium.
RSMeans labor data · Front Range market · Trade mobilizationMany Lakewood lots were platted before modern drainage requirements, so grading, retaining walls, and storm connections are common cost drivers. Narrow infill sites limit where a excavator can stockpile and how a concrete truck can reach the pour. We take off earthwork by cut and fill, price temporary erosion control, and flag where a crane or pump truck will be needed.
Storm drainage · Retaining walls · Erosion control · Sitework Estimating ServicesMaterial pricing in Lakewood is driven by Denver metro suppliers and delivery distance from the I-70 and US-6 corridors. Concrete, lumber and steel quotes move with regional supply, and Colorado sales tax applies to materials, which affects the taxable base of your buyout. We price material from current ZIP-code-adjusted data and separate taxable material from labor so your accounting matches the estimate.
Colorado sales tax · Denver metro suppliers · ZIP-code-adjusted pricingLakewood sits on the west edge of the Denver basin, where expansive clay soils, freeze-thaw cycles and a mostly built-out residential grid change what you actually measure. Here is how those conditions land in each division of a takeoff.
Most Lakewood lots on the west side sit on expansive clay and bentonite, so a takeoff cannot stop at cut and fill. You need over-excavation depths, imported structural fill, moisture conditioning and sometimes chemical stabilization, all measured by cubic yard with a typical 10 to 15 percent shrink or swell factor applied. Utility trenching along older streets means sawcut and removal of asphalt or concrete pavement, bedding stone and backfill in linear feet. For a full breakdown of quantities and units, see our sitework estimating services. Confirm geotechnical recommendations and any city right-of-way requirements with the local building department before you price.
Front Range lumber pricing moves, so a framing takeoff should be broken into wall, floor and roof systems with studs, plates, headers, joists, sheathing and hardware counted separately. Roof pitch and snow load drive rafter or truss sizing, and engineered truss packages need a separate line with delivery and crane time. Waste factors typically run 5 to 10 percent for dimensional lumber and higher for sheet goods cut around hips and valleys. Our framing estimating services page shows how we structure these quantities. Check the current adopted building code for snow load and seismic or wind provisions with the local building department.
Colorado's dry air and cold winters push furnace and humidification capacity, and high-altitude derating affects gas appliance sizing and duct design. A takeoff lists equipment by tonnage or BTU, ductwork by pound and linear foot, refrigerant line sets by foot, and registers by count. Electrical includes service size, panel schedules, branch circuits by device count, and exterior or garage circuits. Plumbing separates rough-in by fixture count, water and drain lines by diameter and length, and gas piping by size. Our MEP estimating services page shows the format. Verify adopted mechanical, plumbing and electrical code editions with the local building department.
Residential foundations here are typically drilled piers, grade beams or stiffened slabs because of soil movement. A takeoff should separate concrete by strength and use: 4,000 psi for footings and piers, 3,500 psi for interior slabs, plus rebar in pounds by bar size and spacing. Vapor barrier, capillary break gravel and post-tension or conventional reinforcement all get their own lines. Flatwork, driveways and approaches are measured separately in square feet with thickness noted. Our foundation estimating services and concrete estimating services cover both the structural and flatwork sides. Verify the adopted code edition and inspection sequence with the local building department.
Lakewood roofs take hail and freeze-thaw, so underlayment, ice and water shield at eaves and valleys, and Class 4 impact-rated shingles are common. A takeoff measures roof area in squares, plus ridge, hip, valley and eave lengths in linear feet, with starter course, drip edge, flashing and ventilation counted as separate items. Steep-slope labor factors and two-story access change the labor hours materially. Tear-off and disposal are their own lines by square and by ton. Our roofing estimating services page covers steep-slope and low-slope assemblies. Confirm local roofing permit and inspection requirements with the local building department.
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. This example prices the drilled pier concrete for a slab-on-grade house on expansive clay, the condition that drives most Lakewood foundation scopes.
Given: 24 piers, 12 in. diameter, 9 ft average depth, 3 ft of the depth in weathered rock. Concrete is 4,000 psi, ordered with a typical 5 percent waste and overpour allowance.
Step 1 — Volume per pier. A 12 in. diameter pier has an area of π × (0.5 ft)² = 0.7854 sq ft. At 9 ft deep, that is 0.7854 × 9 = 7.07 cu ft, or 7.07 ÷ 27 = 0.262 CY per pier.
Step 2 — Total neat volume. 24 piers × 0.262 CY = 6.29 CY.
Step 3 — Waste and overpour. Apply 5 percent: 6.29 × 1.05 = 6.60 CY.
Step 4 — Rock excavation split. 3 ft of 9 ft is rock, so 24 × 3 = 72 LF of rock drilling priced separately from 24 × 6 = 144 LF of soil drilling.
| Step | Calculation | Result | Unit |
|---|---|---|---|
| Pier area | π × 0.5² | 0.7854 | sq ft |
| Volume per pier | 0.7854 × 9 ÷ 27 | 0.262 | CY |
| Neat concrete | 24 × 0.262 | 6.29 | CY |
| With 5% waste | 6.29 × 1.05 | 6.60 | CY |
| Soil drilling | 24 × 6 | 144 | LF |
| Rock drilling | 24 × 3 | 72 | LF |
Two things change this number on a real job. First, actual pier depths come from the geotechnical report, and they often vary across the lot, so a takeoff should carry a depth range rather than a single figure. Second, rebar cages, sonotubes where soil will not stand, and concrete pump or chute access all add lines that a bare volume calculation misses. Our foundation estimating services and concrete estimating services pages show how we structure those items. Confirm the adopted code edition and inspection hold points with the local building department before pricing.
The permit figures come from the U.S. Census Bureau Building Permits Survey for 2025, which counts permits issued by the city itself for new privately-owned residential units only. That means additions, remodels, tenant improvements, commercial buildings and multifamily conversions are not in the count. Lakewood issued 54 such units in 2025, down from 185 in 2024, with all 54 single-family and none multifamily. Use those numbers as a demand signal, not as a full picture of construction activity in the city.
It means fewer new-construction starts competing for the same trades, which can soften framing, concrete and roofing pricing in the short run, but it also means subs are picking and choosing jobs and may carry more mobilization into small scopes. When you estimate, keep labor rates current rather than carrying last year's numbers, and price general conditions honestly. A takeoff built on ZIP-code-adjusted material and labor pricing will track those swings better than a flat national rate.
Expansive clay and bentonite swell and shrink with moisture, so most foundations here use drilled piers, grade beams or stiffened slabs rather than simple spread footings. That adds over-excavation, imported structural fill, moisture conditioning, pier drilling by depth and diameter, and often a void form or cardboard void under grade beams. Each of those is a separate line with its own unit. Read the geotechnical report before you measure, and confirm foundation inspection requirements with the local building department.
Ground snow load and frost depth are set by the adopted code edition and by local amendments, and they drive rafter sizing, truss design, footing depth and exterior water line burial. Rather than assume a number, pull the design criteria off the approved plans or confirm with the local building department. In the takeoff, note the ground snow load, the frost depth and any drift condition on the plans so the framing and foundation quantities can be checked against them.
Yes. Along the West Colfax and Wadsworth corridors and around the Denver Federal Center, much of the work is commercial remodel, tenant improvement and light industrial rather than ground-up residential. Those scopes lean on Division 09 finishes, Division 23 mechanical and Division 26 electrical, plus demolition and partition layout. Our commercial estimating services and industrial estimating services pages cover the format. Send the plans and the spec book together, because TI scope usually lives in the specs more than on the drawings.
We base material and labor on ZIP-code-adjusted pricing, so Lakewood carries its own rates rather than a Denver metro average. That matters for trades with long commutes or tight local availability, where mobilization and overtime creep into the unit price. If you are comparing a Lakewood bid against one in Aurora or Thornton, the material side is close but the labor and general conditions side is not. Our Colorado construction estimating services page explains how we set those rates across the state.
Send the architectural, structural, civil and MEP drawings, the specification book, and the geotechnical report if you have one. For remodels, add existing conditions or as-built drawings and the demolition scope. Tell us the project type, the delivery method and any bid date. We return Excel and PDF takeoffs organized by CSI MasterFormat division with marked-up plan sets, usually within 24 to 48 hours for most projects, with rush turnaround available.
Every takeoff is organized by CSI MasterFormat division and section, with quantities, units and notes tied back to a marked-up plan set so you can trace each number to the sheet it came from. We work in Bluebeam Revu and PlanSwift and price with RSMeans data. That structure lets you drop the quantities straight into your estimating software or hand them to a subcontractor for pricing without re-keying. If you want a different breakdown, tell us before we start.
Yes. We cover the west and north metro, including Arvada, Westminster, Thornton, Aurora, Colorado Springs and Fort Collins. Soil, snow and permitting conditions are similar across much of that ring, but each city has its own adopted code edition, plan review process and inspection sequence, so we do not reuse one city's assumptions for another. See our Arvada construction estimating and Westminster construction estimating pages for the local notes.
Over-excavation and imported structural fill. On expansive clay, the geotechnical report often calls for removing 3 to 6 feet of native soil under the building pad and replacing it with compacted structural fill. That is a large cubic-yard quantity with haul-off, import, moisture conditioning and compaction testing attached, and it is easy to leave out when someone prices from the architectural sheets alone. Read the geotech report and the civil drawings together before you finalize the sitework scope.
Send your drawings, specs and geotechnical report, and we will return a MasterFormat takeoff in Excel and PDF, usually within 24 to 48 hours.
