Construction estimating services in Decatur, IL

We do not publish a flat price because scope drives the effort: a single-trade concrete takeoff on a small shell is a fraction of the work of a full division 03–26 package on a plant expansion. Send the plan set and we will quote the fee before starting. Turnaround is 24–48 hours for most projects, with rush available. The quote reflects the number of sheets, the divisions you want priced, and whether you need marked-up drawings returned with the quantities. There is no charge to review the plans and tell you what the estimate will involve.

Most projects are delivered in 24–48 hours from receipt of a complete plan set and specifications. Rush service is available when your bid date is closer. Incomplete drawings slow the process more than size does, so send the architectural, structural, civil and MEP sheets together if you have them. If only a portion of the set is available, tell us which sheets are missing and we will flag the quantities that depend on them. That way you know which numbers are firm and which are allowances before you submit.

Excel and PDF, organized by CSI MasterFormat division, with the marked-up plan set showing what was measured. You get quantities you can drop into your own pricing, plus a division-level summary. We use Bluebeam Revu, PlanSwift and RSMeans data, with pricing adjusted to the Decatur ZIP code. The marked-up drawings let your estimator or project manager trace any line back to the sheet it came from. If you want the Excel workbook structured to match your own bid form, tell us at kickoff and we will set it up that way.

Both. Material and labor pricing is ZIP-code adjusted, so the labor component reflects the Decatur market rather than a national average. Where you have your own crew rates or a subcontractor quote, we can carry your numbers instead and keep our quantities as the check. That is common on prevailing-wage work and on projects where a local subcontractor has already given you a firm number. We show the labor and material split separately so you can swap either side without rebuilding the takeoff.

The figures come from the U.S. Census Bureau Building Permits Survey for 2025. They count new privately-owned residential units permitted by the city itself — 3 units, all single-family, with $3M in permitted value. They do not include commercial, industrial or renovation permits, so they understate total construction activity in Decatur. Use them as a signal about residential volume only, not as a measure of the commercial and industrial work that drives most takeoff requests in Macon County. The same survey ranked Decatur 23rd of 25 covered Illinois cities by units.

Footing depth is set by the geotechnical report and the locally adopted code, and in this part of Illinois frost protection typically puts footing bottoms around 36–42 inches below grade. Confirm the adopted code edition and the required frost depth with the local building department, and use the geotech report for bearing capacity and undercut. Those two documents control the quantity: frost depth sets stem wall height and form area, while the geotech sets how much unsuitable soil comes out and how much granular backfill goes in.

Yes. Renovation takeoffs are slower than new construction because existing conditions are not dimensioned on the drawings. We measure from the plan and flag assumptions for field verification — deck condition on re-roofs, wall substrate behind finishes, and existing MEP routing are the usual unknowns. Those flagged items keep your bid from carrying an invisible contingency. On downtown masonry buildings, we also separate selective demolition from new work so the disposal and patching quantities do not get buried in the trade that follows.

Yes. We cover Macon County and the surrounding region, and nearby markets including Bloomington, Arlington Heights, Evanston, Schaumburg, Bolingbrook and Palatine. Pricing stays ZIP-code adjusted for each location, so quantities travel with the project and the labor and material rates follow the site. That matters when the same building type is bid in two markets, because the quantity takeoff is identical but the labor cost is not. See our Illinois construction estimating page for how we handle projects across the state.

A complete plan set and specifications, the bid date, and the trade scope you want priced. If you only need one division, say so and we will measure that division and leave the rest alone. Marked-up drawings from a previous estimate are also useful, because they show us what was already counted. Tell us the bid form structure if you have one, and note any alternates or unit prices the owner requires. The more of that you send up front, the fewer assumptions end up in the final document.

Yes. Multi-family takeoffs are unit-type driven: we build a quantity per unit type, then multiply by the unit mix and add the common areas, corridors, stairs and roof. Decatur permitted no new multi-family units in 2025, but renovation and adaptive reuse work still comes through. Our multi-family estimating services cover the full division set. On conversions of older buildings, we separate the shell work from the unit fit-out so you can phase the pricing and see which portion carries the risk.
