Where bids go wrong
What other rebar estimates miss.
Lap lengths and development, which add real tonnage over a long wall or slab.
Chairs, bolsters, ties and supports — small money per piece, large money per job.
Dowels, couplers and epoxy-coated bar where the drawings switch material mid-detail.
Placing labor priced separately from supply, because the crews and rates differ.

FAQ
Rebar Estimating, answered.
Talk to an estimator
Not a salesperson. Same-day answers on working days.
+1 518 974 7222[email protected]Do you include laps and splices?
Yes. Lap lengths follow the structural notes and are added to bar lengths, so the tonnage reflects what is actually placed.
Can you provide a bar list?
We provide tonnage by element and size. A full fabrication bar list is detailing work and is quoted separately.
Can you use our cost book and labor rates?
Yes, and we prefer it. Your historical costs reflect your crews and your suppliers better than any published average. Send the template and we work inside it.
How does pricing work?
Pricing is per project and quoted before any work starts — no retainer, no minimum volume and no subscription.
Do you sign NDAs?
Yes. Drawings, specifications and pricing are treated as confidential by default, and we sign your NDA on request before any documents change hands.
