Construction takeoff checklist for contractors

Most quote delays aren't the supplier's fault. They come from a takeoff that can't be priced. The usual workflow is the same everywhere: finish the takeoff, send a material list with quantities, then wait while suppliers work through it. A clean list shortens the wait. A messy one restarts it, because every question a supplier has to ask adds a round trip. Run through this checklist before you send anything out.

Before you count

• Confirm you have the latest drawing revision.
• Note the scale, and any addenda that change quantities.
• List the scopes you're buying vs. subcontracting.
• Check the spec book for named products and approved equals.

Per line item

• Description with spec: species and grade, size, gauge, rating, finish, or whatever changes the price.
• Unit of measure: one unit per line, consistent across the whole list.
• Quantity including waste factor: and say whether the waste is already included.
• Acceptable substitutions: or mark the line "no substitutions".
• Phase or area: so partial deliveries can be scheduled.

The lines contractors forget

• Fasteners, adhesives, sealants and tape.
• Flashing, trims, closures and transitions.
• Blocking, backing and temporary bracing.
• Anchors, straps and connectors.
• Consumables: blades, bits, form oil.
• Site protection and dumpster or haul-off.

Spec details by trade (what changes the price)

If the job is in the Fort Worth pilot, those trades already have their own pages: plumbing supply houses in Fort Worth, ready-mix concrete suppliers in Fort Worth, lumber suppliers in Fort Worth, and HVAC equipment suppliers in Fort Worth. You still choose which of them receive the list.

Worked example: waste factor

You need 96 sheets of sheathing by area. Do you send "96" or "96 + waste"? Either is fine if you say which. Two suppliers reading the same number differently is how you end up with quotes that look comparable but aren't. Write it as "96 sheets (waste included)" or "88 sheets net, add 10%".

Before you send the RFQ

• Every line has a description, unit and quantity, with no blanks.
• Duplicate lines are merged.
• The jobsite address and needed-by date are attached.
• Delivery or will-call is stated.
• The list is saved as CSV or a plain list, so any supplier can price it.
• The quote validity you need is stated.

Common takeoff errors that cost money

• Mixed units: "LF" on one line and "pcs" on the next for the same item.
• Rolled-up lines: "framing hardware – lot" can't be priced or compared.
• Old revisions: quantities from a superseded sheet.
• Missing phases: everything delivered at once to a site with no laydown space.

Takeoff for services, not just materials

List services such as a pump truck, a crane pick or a boom delivery as their own lines. See how to request services in the same RFQ.

How detailed is detailed enough?

A good test: could a counter person who has never seen your drawings price the line without calling you? If not, add the missing spec. If a line needs a drawing to be understood (custom trim profiles, bent rebar schedules, special-order windows), attach the specific sheet reference rather than the whole plan set, and say which line it belongs to.

Keep a reusable template

Most crews build similar scopes again and again. Save your last clean takeoff as a template with the forgotten lines already included, then edit quantities for the next job. It's faster than starting from zero, and it keeps your units and descriptions consistent, so quotes from different jobs can be compared over time.

Revisions after the RFQ goes out

If the drawings change after you send the list, send a revised list to every supplier with the changed lines clearly marked. Don't call one supplier with the change and forget the others: their quotes will no longer cover the same scope.

Organize the list the way suppliers stock it

Group lines by category (lumber, sheathing, hardware, concrete accessories) rather than by room or drawing sheet. A supply house often prices categories at different desks or from different systems. A grouped list lets each desk price its section without hunting, and it makes the returned quote easier for you to compare against the original.

Who should check the takeoff

On larger jobs, have a second person spot-check the highest-cost lines and the "forgotten" categories above before the list goes out. A single missed line found after award means a separate small order, often with its own delivery charge. Ten minutes of review before sending is cheaper.

From takeoff to quotes

Bluezupply imports your list from PDF, Excel, CSV or pasted text, and lets you edit or delete lines before it goes out. Then you pick the suppliers you want, and it requests quotes from all of them at once: one request, multiple quotes.
