How to scope a renovation in 60 seconds (and why your hand-written estimate keeps losing jobs)

The first thing I noticed when I started running renovation jobs was that the bidding process was killing us. Every prospect wanted a "rough estimate" the same day. Hand-writing one took 2-4 hours per project. Half the time we'd quote, never hear back, and the time was just gone.

So I built the loop into software. Here's what the 60-second version looks like.

The five steps

1. RoomPlan walk (10-15 minutes on site).

Open the iOS scanner, walk the rooms in scope. The output is a parametric 3D model — walls, doors, windows, furniture, all labeled and dimensioned. Free, no subscription, no watermark.

2. Notes drop (30 seconds).

On the same iPhone, tap a few notes: "client wants quartz counters, slate floor, paint everything off-white, keep existing cabinets." Maybe attach 2-3 close-up photos of conditions worth flagging.

3. Upload (10 seconds).

The scan + notes + photos sync to your BlueWave project room.

4. AI scope generation (60 seconds).

The scope generator reads the RoomPlan model, the notes, and the photos. It writes a phase-by-phase scope of work: demo, framing changes, electrical, plumbing, drywall + paint, finish. Each phase has a labor range, a materials range, and a contingency. Hawaii GET gross-up is computed. The whole document is ~500-1500 words.

5. Review + send (5 minutes).

The scope opens in an editor in your tenant. You scan it for anything wrong — typos, line items you'd remove, ranges you'd tighten — and edit in place. When it looks right, hit "send as lead" and a draft email goes to the prospect with the scope attached as a PDF, the scan as a 3D viewer link, and a Calendly link to book the site visit.

Total elapsed time from boots on site to scope in the client's inbox: under 20 minutes for most jobs.

Why hand-writing loses

When a prospect calls four GCs the same week, the one who responds first usually wins — not the one with the cheapest quote. Speed beats price more often than people admit.

If you hand-write your scopes, the typical cycle is:

  • Site visit Monday.
  • 3-4 hours that night writing the scope.
  • Tuesday morning send it.
  • Client already met with two other GCs.
  • If you generate it in 60 seconds:

  • Site visit Monday morning.
  • Scope in their inbox Monday at lunch.
  • You're the first response and the most detailed one.
  • I've watched our close rate go from ~15% to ~40% on the prospects where we hit the 60-second loop. Same prospects, same prices, just earlier.

    What the scope actually looks like

    A real example (numbers obscured for client privacy) from a recent Oahu condo refinish:

    > Phase 1 — Demo + protection ($X,XXX labor, $X,XXX materials)

    > Remove existing flooring (slate + carpet, ~480 sqft). Protect cabinetry, fixtures, and HVAC vents. Disposal via on-site bin.

    >

    > Phase 2 — Subfloor prep ($XXX labor, $XXX materials)

    > Self-leveler over existing slab (~480 sqft). Verify flatness <1/8" over 10ft.

    >

    > Phase 3 — Flooring install ($X,XXX labor, $X,XXX materials)

    > White oak engineered, 6" wide plank, glue-down. Schluter trim at transitions. Furniture float through 72 hours.

    >

    > ... and so on for 6-8 phases.

    Each phase has the labor hours assumed, the materials line items, and a 10-15% contingency. Hawaii §237-13(3)(B) GET deduction tracking is set up automatically.

    What it can't do

    The scope generator can't:

  • Replace a structural engineer when something needs one.
  • See into walls. It'll flag "possible mechanical chase here" but a real on-site inspection is still required.
  • Price subs you haven't given it. If you've never told it what your tile setter charges, it'll use Honolulu averages.
  • Negotiate scope with the client. The first version is a starting point; the conversation happens after.
  • It can:

  • Get you to a defensible first scope 50× faster than hand-writing.
  • Keep the format consistent across every prospect so you stop reinventing the document.
  • Compute the Hawaii GET correctly every time so you stop accidentally underbidding.
  • Try the loop on your next site walk

    [Book a demo](/booking) — we'll walk you through the scope generator on a real site of yours and set up your tenant on the call. If you've got an iPhone with LiDAR and a site walk on your calendar this week, you have what you need to try it.

    The first one will feel weird. By the third one, you won't go back to hand-writing.
