How it works

From drawing upload to bid-ready deliverables.

Five steps that replace spreadsheets, plugins, and manual handoffs with one estimating workflow — from plan upload through side-by-side bid comparison.

Step 01 · Upload

Bring in the plan set.

Drop in PDFs, plan sets, or Revit 3D models. Axiom keeps every revision, addendum, and RFI in one version-controlled document store.

  • PDFs and Revit 3D models
  • Unlimited plan sets and revisions
  • No browser upload size caps
Interactive demo

Try it: drop a plan set and watch the estimate build.

A simulated run of the real workflow — upload a PDF or Revit model, watch quantities get extracted sheet by sheet, see them land as CSI MasterFormat line items, then level subcontractor bids side-by-side against your own estimate. Nothing leaves your browser.

Or start with the Naples AOD sample — five coordinated sheets or its representative Revit model.

CSI MasterFormat estimate

Line items appear here as takeoff quantities are pushed into the estimate.

Naples AOD demo: 12,450 SF, $1,901,752 direct cost ($153/SF), and $1,978,392 including 1% insurance and 3% fee. Dropped files stay on your device and are never uploaded.

Capabilities

Every capability, shown on the real product.

Axiom Estimating unifies drawings, takeoffs, estimates, bid leveling, and proposals in one workspace — no plugins, no spreadsheets, no lock‑in. Every screen below is the real product working from one source of truth.

01 · Manual & Automated Takeoffs

Measure straight from the drawings.

Calibrate any PDF and click to measure areas, lengths, and counts — or let the takeoff engine extract CSI‑coded quantities from the plan set automatically. Revit 3D models auto‑quantify walls, doors, windows, and slabs.

  • PDF + Revit 3D support
  • Area · length · count
  • CSI-coded line items

02 · CSI-Native Estimates

MasterFormat from division to line item.

Estimate by CSI divisions and sub‑codes or roll up industry‑standard assemblies. Editable unit costs, regional labor factors, and general conditions live alongside every line.

  • Assembly library
  • Regional labor factors
  • Live division totals

03 · Bid Leveling

Normalize scope and price by CSI code across every bid you receive. Variance flags surface risk before award day, and templated leveling emails go out to each sub in one click.

  • Division-level comparison
  • Automatic variance flags
  • Templated sub emails
