Takeoff. Protect. Punchlist. Draw. Receipts. (Beta)

Takeoffs, punchlists, lien waivers, draws, receipts and more.

Build it with Buildlab.

Buildlab Digital was built on the jobsite, not in a conference room. Takeoffs, count every slab, frame, cabinet, appliance and fixture by unit. Draft lien waivers off the same project file, get it signed, and hand the lender a bank-ready PDF with the audit trail stapled on. Make your punch list, find the issue, flag it, fix it, and track it down to each room and location. Get funded with the draw tool, which tracks budget vs. actual, line by line in real time with PDF back up and compilation tools, let the boss argue with the ledger. One drafting table. More cooking in the lab.

Takeoff (beta)

Takeoff

Measure it once. Slabs, frames, cabinets, appliances, tile, MEP. Each type gets the fields that item actually needs. Sort by unit. Export the cut list. Clone the bid into an as-built when the job closes.

Punchlist (beta)

Punchlist

Find it. Flag it. Fix it. Every item has a unit, common, or exterior location. Set it once, log a dozen defects, export the report by building and floor.

Draw (beta)

Draw

Budget vs. actual, per line. Debit spend against categories. Material needs a receipt. Vendor payments need payment backup and a lien waiver. Export the draw CSV or a job snapshot. Let the boss argue with the ledger.

Receipts (beta)

Account

Your drafting table

Vendors, projects, takeoffs, punchlists, draws, receipts, waivers. One file, all connected. Nothing gets typed twice.

Chalk Line

Pin it to the plan

Click the plan and the location fills itself. Or just work the list.

JobBox

Get the picture

Before drywall or after. Point, shoot, it's on the line.

Cut List

Hand it to the supplier

Sort by unit or by type. Export. Done.

As-built

Bid today, as-built later

Clone the takeoff. See the variance. Argue with numbers, not memory.

Measured the way the trade measures it

A slab wants size, handing and hardware. A frame wants rough opening. Pick the type and the form changes with it.

Pull the job off the paperwork

Attach the bill, paste the invoice, or photograph the pay app. Parties, job and amount land in the right boxes.

Keep the file

Owners, GCs, subs, jobs. The next waiver starts where the last one ended.

Sign in the field

Send a private link. The sub signs on their phone. You get a clean bank PDF with date, email, IP and a field digest.

Still in the lab

We're not stopping at takeoffs, punchlists, draws, receipts, and waivers. More valuable capabilities coming soon.
