What a detailed cost estimate gives you
A detailed estimate, sometimes called a bottom-up or unit-cost estimate, is the document you bid from. It starts with a complete quantity takeoff and turns every measured quantity into dollars. Each line has a quantity, a unit, a material cost, a labor cost based on crew productivity, and an equipment cost where it applies.
For Kansas general contractors, the estimate is also a management tool. The same workbook becomes your buyout budget, your schedule of values and the baseline for change orders. That only works if the estimate is organized the way the job will be built and bought, which is why we follow CSI MasterFormat divisions and keep self-performed work separate from subcontracted scopes.
How we build a Kansas cost estimate
- Document review. We read the drawings, project manual, addenda and bid form before quoting. Missing sheets and conflicting details are flagged in writing.
- Takeoff by division. Quantities are measured digitally and tagged to the sheet and detail they came from, so anyone on your team can verify them.
- Labor pricing. Labor is priced from crew composition and productivity, not a lump percentage. We use Kansas wage levels for the region the project is in, or your own rates.
- Material and freight. Material is priced from current Kansas supplier pricing. For projects in western Kansas we add realistic freight and delivery minimums rather than assuming Kansas City or Wichita pricing.
- Sales tax. Kansas taxes materials, and taxes labor differently on original construction and remodel work. Exempt owners can issue a Project Exemption Certificate. We apply the right treatment and the local rate for the delivery address. See our Kansas contractor sales tax guide.
- General conditions and markups. Supervision, temporary facilities, bonds, insurance, permits, contingency, overhead and profit, each shown as its own line.
- Second-estimator review. A second estimator checks quantities against the drawings and the scope against the specifications before release.
Kansas conditions we price that national estimates miss
| Condition | Where it shows up | Effect on the estimate |
|---|---|---|
| Frost depth | Footings and foundation walls | About 30 in. in south-central Kansas, 36 in. or more around Kansas City and Lawrence, so excavation, concrete and rebar change |
| Expansive clay | Slabs, piers, flatwork | Over-excavation, moisture conditioning, void forms or structural slabs in eastern Kansas |
| Hail and wind | Roofing, siding, glazing, RTUs | Impact-rated roofing, uplift fastening, hail guards on condensers |
| Tornado shelters | Schools, emergency facilities | ICC 500 storm shelters where the 2015 or later IBC is adopted |
| Local code edition | Every trade | Home rule means Wichita, Overland Park and Topeka can each enforce different editions |
| Federal funding | Labor | Davis-Bacon wage determinations on federally assisted projects |
Each of these is covered in depth in our guides on clay soils, building codes by city and prevailing wage.
Who uses our cost estimates
- General contractors who need overflow capacity in bid season or a check estimate against their own number.
- Developers and owners who want an independent estimate before signing a GMP or lump-sum contract.
- Lenders and investors who need a third-party budget review for a construction loan draw schedule.
- Architects who need a cost check at design development to stay within an owner's budget.
Deliverables
You receive a native Excel workbook with live formulas, a PDF summary by division, marked-up takeoff sheets, and a written list of inclusions, exclusions, allowances and clarifications you can paste straight into your proposal. Alternates and unit prices are broken out to match the bid form.
When a different estimate fits better
If your drawings are still schematic, a preliminary budget estimate is faster and cheaper. If you already have strong pricing and only need quantities, order a quantity takeoff. For a single trade, see our trade takeoffs.
Frequently asked questions
What is included in a detailed construction cost estimate?
Quantities for every scope item, unit costs for labor, material and equipment, subcontractor plugs where you use subs, general conditions, sales tax, contingency, overhead and profit. We organize everything by CSI MasterFormat division and reference each line to the drawing sheet.
How long does a detailed estimate take?
A custom home usually takes two to four business days. A multi-trade commercial or industrial estimate usually takes four to ten business days depending on plan-set size. Your quote states a committed date.
Can you use my labor rates and markups?
Yes. Send your crew rates, burden and markup structure and we will build them into the workbook. We can also show Kansas market rates side by side.
Do you estimate projects in the Kansas City, Missouri side of the metro?
Yes. Kansas is our focus. Kansas City contractors often bid both sides of State Line Road, so Missouri-side metro projects can be priced with Missouri tax rules on request.
