Questions

How accurate is the AI takeoff?

Rebar proposes every run, unit, and spec check, and your estimators review it before it's used. Every item traces back to where it sits on the plan, so it's quick to check.

What does Rebar take off?

Ductwork with length, weight, material, system, and accessories, plus equipment from the mechanical schedules and the spec requirements that apply to them.

Can we correct what the AI finds?

Yes. Every item can be edited or overridden, and nothing reaches a bid until someone on your team confirms it.

How does Rebar handle addendums?

Addendums stay with the original job, so your team reviews each revision against the plan set it changes.

How does onboarding work?

We onboard your estimating team directly, onsite or virtually, and stay on hand with hands-on support after you go live.

Is our bid data secure?

Yes. Rebar is SOC 2 Type I certified, every company's data is isolated, and projects under NDA stay protected.
