§ Denver fast facts

QUICK ANSWERS.

Do I need a geotechnical report to pull a foundation permit in Denver?

Not always, but Denver Building and Fire Code inspectors can require a soils letter from a licensed geotechnical engineer on sites with known expansive or unstable soils — particularly in older neighborhoods and hillside lots. Budget $800–$1,500 for a standard geotechnical letter and include it as a line item or owner-furnished scope in your bid so there are no surprises at permit submittal.

Is radon rough-in required on new foundation pours in Denver?

Denver County and most surrounding jurisdictions in the metro are EPA Radon Zone 1. The 2021 IRC Appendix F (radon control) is adopted by many Front Range jurisdictions, and inspectors in Denver, Aurora, and Lakewood routinely require passive radon rough-in — sub-slab polyethylene, 4-inch PVC riser, and a future-fan junction box — as part of new residential foundation work. Confirm with the specific AHJ at permit pre-application, and include the rough-in in your base scope rather than pricing it as an alternate.

LOCAL FACTS.

DENVER METRO FOUNDATION LABOR RATE (JOURNEYMAN CONCRETE/FOUNDATION CREW).

Approximately $38–$52/hr for journeyman foundation laborers in the Denver-Aurora MSA as of 2024, reflecting Colorado's construction labor market tightness and prevailing wage pressure from public projects along the Front Range.

DENVER BUILDING DEPARTMENT STRUCTURAL PERMIT FEE (TYPICAL RESIDENTIAL FOUNDATION).

Denver Community Planning and Development charges plan review plus permit fees based on valuation; a $60,000–$80,000 foundation-only project typically generates $800–$1,400 in combined permit and plan review fees. Structural permits for expansive soil sites often require a soils report, adding $500–$1,500 in third-party geotechnical costs before permit issuance.

FROST DEPTH REQUIREMENT — DENVER AND COLORADO FRONT RANGE.

36 inches below finished grade per the 2021 IRC as adopted by Colorado (IRC Table R301.2(1) local amendment). This is deeper than most Sun Belt markets and directly increases footing concrete volume and excavation depth on every job.

EXPANSIVE SOIL PREVALENCE IN DENVER.

The Colorado Geological Survey classifies large portions of the Denver metropolitan area — including areas of Jefferson, Arapahoe, and Douglas counties — as high-risk for expansive soil movement. Insurance claims related to foundation damage from expansive soils rank among the costliest property damage categories in Colorado, making accurate soil-condition line items in bids a liability issue, not just a pricing issue.

§ Why foundations pros in Denver use Estimate.Pro

THE BID ENGINE.

## Foundation Estimating in Denver Is Not the Same as Anywhere Else Denver sits on some of the most problematic soil in the country. Expansive clay — bentonite-rich in many Front Range neighborhoods — shifts with moisture cycles and forces you to engineer every foundation differently. Add a 36-inch frost depth requirement, strict Jefferson and Arapahoe county setback rules, and permit timelines that can stretch two weeks for structural work, and you have an estimating environment where a generic spreadsheet will get you beat or get you burned. Estimate.Pro is built for foundation contractors who need to price that complexity fast and accurately. ## What Makes Denver Foundation Jobs Harder to Estimate **Expansive soils add line items most software ignores.** Geotechnical reports often require moisture-conditioning, over-excavation, or structural fill replacement before you ever pour. Those costs — haul-off, import fill, compaction testing — belong in your bid. Estimate.Pro gives you a saved material cost workspace where you store your regional pricing for engineered fill, Cathodic protection pipe, and drainage aggregate. You update it once; it flows into every future estimate. **Frost depth drives footing dimensions.** At 36 inches below grade per the 2021 IRC as adopted by Colorado, your footing quantities differ from a Phoenix or Dallas job. The scope-of-work engine in Estimate.Pro accounts for depth inputs when it generates your material and labor takeoffs — concrete volume, form board footage, rebar schedule — so you are not back-calculating by hand after the AI draft lands. **Radon rough-in is close to universal.** Denver sits in EPA Radon Zone 1, the highest-risk classification. Building departments in Denver proper, Aurora, and Lakewood routinely require a passive radon mitigation rough-in — sub-slab poly, 4-inch PVC riser, roof penetration — during new foundation pours. That scope belongs in your base bid, not as an afterthought add-on. ## From Walkthrough to Bid in 8 Minutes The typical Estimate.Pro workflow for a Denver foundation job: 1. **Walkthrough the site.** Use AR measurement on a supported device to capture footprint dimensions. Camera-only shots are flagged as estimates so you know what needs field verification. 2. **Describe the job.** Dictate or type: full perimeter foundation, 36-inch frost footings, 4-inch basement slab, expansive soil over-excavation, radon rough-in, waterproofing membrane. 3. **Get the AI scope-of-work.** The system drafts line items — excavation, forming, concrete, rebar, anchor bolts, waterproofing, backfill, radon rough-in — in seconds. 4. **Apply your Denver pricing.** Your saved workspace pulls in your current Ready-Mix concrete cost (delivered in the metro), labor rates, and subcontractor allowances. 5. **Send the bid.** Pro and Elite plans let you export polished proposals. Elite adds Stripe Connect for in-app invoicing at 0% platform fee. Median time from walkthrough start to a sendable bid: 8 minutes. ## Codes and Standards That Belong in Your Scope Notes - **2021 IRC Section R403** — footing depth and size minimums as adopted by Colorado - **Denver Building and Fire Code** — local amendments to the IRC for expansive soil sites; some zones require a licensed geotechnical engineer's letter before permit issuance - **EPA Map of Radon Zones** — Denver County and most surrounding counties are Zone 1 (>4 pCi/L predicted) - **ASTM D1557** — Modified Proctor compaction standard referenced by Denver-area geotechnical reports for structural fill When you attach scope notes referencing these standards, you separate yourself from competitors handing over a one-page number with no backup. ## Pricing That Matches How You Actually Work Estimate.Pro is free to start — no credit card, no trial clock. When your volume justifies it, Pro is $39 per seat per month. Elite is $79 and adds Stripe Connect invoicing and export workflows. If you run a crew and need multiple seats, the Crew plan is $399 flat per month. There is no per-bid fee. A slow month with three jobs costs the same as a busy month with thirty. ## The Bottom Line for Denver Foundation Contractors Denver's soil conditions, frost requirements, radon rules, and active permit offices all add scope that other markets do not see. If your estimating tool does not account for that, you are either leaving money on the table or losing bids you should have won. Estimate.Pro structures the estimate around your actual job conditions — not a national average — and gets you to a sendable number before the next contractor finishes their site visit.
