FOUNDATIONS ESTIMATING.

## Foundation Estimating in Washington, DC Foundation work in Washington, DC comes with a short list of variables that inflate bid complexity fast. You're dealing with expansive marine clay soils across much of the District, century-old row house foundations that may be rubble stone or unreinforced brick, and a permitting apparatus that runs through DC's Department of Consumer and Regulatory Affairs (DCRA). Add in proximity to the Potomac and Anacostia floodplains, and every foundation job carries site-specific risk that a flat-rate guess won't cover. Estimate.Pro gives you a structured walkthrough that captures those variables before you price a single cubic yard. ### Why DC Foundation Bids Go Wrong Most underbids on DC foundation jobs trace back to three missed line items: 1. **Soil conditions.** The Coastal Plain soils east of Rock Creek Park and in the Anacostia corridor have bearing capacities that regularly require deeper footings or helical pier solutions. A scope-of-work that doesn't flag soil class adds cost you'll absorb later. 2. **Historic district constraints.** Roughly a third of DC's residential stock sits inside a historic district overseen by the Historic Preservation Office (HPO). Underpinning or foundation replacement in these zones may trigger HPO review on top of standard DCRA structural permits. That review window affects your schedule and your carrying costs. 3. **Permit fees and bonding.** DC charges structural permit fees on a sliding scale tied to project valuation. A $150,000 foundation replacement carries a permit fee materially higher than a repair job. Your bid needs to include that line item, not absorb it. ### What Estimate.Pro Does for Foundation Contractors The app walks you through the job site using your phone. On supported devices, ONNX-assisted AR measurement captures linear footage of footing runs, wall heights, and pier spacing directly from the camera feed. Photos taken on unsupported devices are still measured and clearly marked as estimates so you know which numbers to verify. From the walkthrough, the AI generates a scope-of-work that calls out: - Excavation volume and disposal - Footing and stem wall concrete (by CY) - Rebar schedule - Waterproofing membrane and drainage board - Underpinning or helical pier counts when flagged - Permit allowance line items You price it against your saved material cost workspace — your supplier rates, not national averages — and a sendable bid is ready in a median of 8 minutes from the end of the walkthrough. ### Local Codes That Affect Your Scope DC adopts the International Building Code with District amendments. Current structural work runs under the **DC Construction Codes, 2020 edition**, which incorporates IBC 2018 with local modifications. Foundation designs must meet the geotechnical requirements of **DC Municipal Regulations Title 12**, which specifies minimum footing depths (generally 2 ft 6 in below finished grade for frost protection) and soil bearing assumptions. For projects near the floodplain, FEMA Flood Insurance Rate Map (FIRM) panels covering DC designate Base Flood Elevation requirements that affect foundation top-of-wall height and any below-grade finished space. Estimate.Pro's scope template includes a floodplain flag so the spec reflects that requirement before you send the bid. ### Pricing and Platform Fees Estimate.Pro runs on a free forever tier — no credit card, no trial countdown. When you're ready to process payments through Stripe Connect, the Pro plan at $39 per seat per month carries a 3% platform fee. Pro+ eliminates that fee entirely. Elite, at $79 per seat per month, adds invoice exports and full Stripe Connect workflows. The Crew flat rate at $399 per month covers unlimited seats for larger foundation crews working multiple DC sites simultaneously. No one charges you to build your first estimate. That's the point. ### Who This Is For Foundation contractors working in DC who run residential underpinning, crawl space encapsulation, slab repair, new construction footings, or waterproofing scopes. If your bids currently live in a spreadsheet or a legal pad, Estimate.Pro replaces that with a documented, reproducible process that shows clients a professional scope — not a number on a Post-it. The District's project pipeline — row house renovations, new ADU construction enabled by the updated zoning code, and commercial tenant improvement work — keeps foundation contractors busy year-round. The contractors who win those jobs consistently are the ones whose bids arrive first and read clearly. Eight minutes from walkthrough to sendable bid is how you get there.
