Your bid process is ready for an upgrade.It needs a system that stands up to the challenge.

Bid intelligence with Rex AI builds on the already capable workflows KNTRCTR offers. You need a tool that ensures all bids are accounted for and compared properly. While your partners need a process they can trust.

Rex Build splits the project.Every trade gets its own package.

Twenty bid packages, one building. Attach the drawings, the budget, and your notes. Rex drafts a package for each trade and lines them up on the project. You still decide what goes out.

The map stays open on that project, so you can see which trades are covered, which are still thin, and which came in over.

  • Every package on the project, with status, budget, and the lowest bid.
  • Who priced what. Who won.
  • What is closing this week across every job you have out.

Set what gets priced.Before the numbers come in, not after.

Set the scope

Build the line items once, save it as a template, and reuse it on the next package. Bids come back against your form, so the comparison is done before you open it.

  • Line items by lump sum, unit price, or a yes or no you need answered.
  • Exclusions and alternates in their own place, not buried in a cover letter.
  • Qualifications & Requirements sit on the page so your partners know what is required.
  • Attachments sit right on the ITB so your partners have quick access to important details and drawings.

The gap you are hunting for is a scope gap. This is what makes it visible in a glance instead of an afternoon.

Company lists sit with the work.Invite the trade, not one inbox at a time.

Your network and lists

Electrical, glazing, the door supplier you call on every building. Save them as lists. The next package gets sent to all the companies in that list.

When you go to submit your ITB, you can send to the list with a click of a button. Anytime you update the job afterwards, or send out a message, everyone on this list gets the word.

  • Subcontractor lists and supplier lists, kept by trade.
  • Upload a CSV. The lists build from the trade column.
  • Jobs stay private unless you choose public.

Subs hold the number until the last minute so it cannot be shopped. The quote hits your inbox as the package is closing. Retyping every line is how a bid gets left off the comparison.

Drop the file on the package and paste the email beside it. Rex reads the quote onto your line items. In seconds that price is sitting on the form, ready to compare with the bids that came in on time. You still check the total before it is saved.

  • Last-minute pricing still makes the sheet.
  • Rex fills the scope items from the quote and the email.
  • Exclusions in the message land on the line they belong to.

Rex AI reads the bids.General contractors need specifics.

Learn more about Rex

Rex reads every bid against the request before you award. Missing lines. A number that is low because something is not in it. A quote that skipped the form entirely, with the pricing still sitting in the PDF.

Give Rex standing instructions and he checks for the same thing on every job. Got burned on a package once? He watches for it from now on.

Rex analyzes. You decide.

The call is still yours.

The job is not in one estimator's inbox.It is on the job, where the team can see it.

Teammates on a job

Multiple estimators, a precon lead, a PM waiting for turnover. Everybody looks at the same job, the same bidders, the same numbers. Add teammates with their own logins so estimating can hand that file to the field.

That is people from your company. Who you invite to bid is a different block: saved lists, a name, or an email.

  • Each teammate has their own login. No shared passwords.
  • The thread with each bidder stays on the job, not in a personal inbox.
  • When the estimator who ran it moves on, the job does not move with them.

The scope changed Wednesday.Everyone invited knew Wednesday.

Broadcast and job updates

Adjust a requirement, add a drawing, change a date. Every invited bidder gets it the moment you save. Not in a digest. Not when somebody remembers to forward it.

Send one message to the room when you need prices in, and each bidder gets it on their own thread.

Prequal tells you they are insured.The record tells you if they showed up.

Reviews for primes

You already vet people before they bid. Bonding, insurance, safety, references. That is a snapshot taken before any work happens.

What you do not have is the other half. Did they man it. Did they hold the schedule. Did they close out without a fight. Would you run with them again.

Score the job when it closes. Ten categories and one overall. Keep it internal, share it with your team, or publish the scores to the network. The next time that sub bids, it is sitting next to their number.

The estimator who wrote it can leave. The record does not.

Rex remembers

When Rex reads the next bid, he stacks that score up with the number. The lowest bid is not always the safest bet.

Leveling, the team, and the record.

What is Rex Build?

Rex Build drafts the bid packages from the documents you already have. Attach drawings, a budget, and notes, and Rex proposes a package for each trade or crew.

Those packages sit together on the project, with the map open, so you can see who is pricing what before anyone is invited. Nothing goes out until you review the draft and send the invitations yourself.

Can Rex add a bid that arrives by email at the deadline?

Yes. Subcontractors often hold the number until the bid closes so it cannot be shopped. The PDF lands in the inbox as the package is closing, and retyping every line is how a bid gets left off the comparison.

Drop the quote on the package and paste the email beside it. Rex reads the price onto the same scope lines in seconds. You confirm the total before it is saved. That bid then sits on the form with the quotes that came in through the invitation, ready to compare.

Where do qualifications, requirements, and drawings sit on an invitation to bid?

Qualifications and requirements sit on the bid request, so the companies you invite can see what is required before they price.

Attachments sit on the same invitation. Drawings and the rest of the package are on the page, so partners are not hunting a separate email for the details they need to bid.

Set the scope on the request

How can I invite my existing subcontractors to a bid package?

You can invite existing subcontractors directly, invite from saved lists, or use mass CSV upload to bring in your current contacts first. You can also email a partner who is not on KNTRCTR yet.

When you submit the invitation, you can send it to a saved list in one click. Everyone on that list gets the request. Later updates and messages go to those same companies.

Bid packages stay private unless you choose public inside KNTRCTR. Public still means signed-in KNTRCTR users, not the open web.

On the bid package, that invite block is labeled Crew Control. It is who you invite to bid, not the people on your own team.

Once your network is organized, posting a bid package and inviting your known subcontractors takes only a few clicks.

Your network and lists

Can I level my subcontractor bids in KNTRCTR?

Yes. KNTRCTR includes bid leveling so you can normalize subcontractor bids line by line before award.

Bid leveling keeps the original bidder response visible while you enter separate leveled values for comparison.

You can level quote expectations (including unit rate and quantity on unit-priced lines), level provisional / additional amounts (amount, multiplier, and include/exclude), add bid adjustments as increases or decreases, and add leveled notes under Pricing, Scope, and Timeline.

The leveled amount is calculated from the original bid amount, plus or minus expectation-leveling differences, plus or minus provisional leveling differences, plus or minus bid adjustments.

Bid leveling is poster-side only and locks once the bid package is awarded.

Compare and level bids

Can I give Rex directions on what to look into?

Yes. AI Checks are standing questions your company sets once, and Rex answers them on every bid package. Teams use them for the things they always want confirmed, such as how each bid compares to the internal budget, or whether a quote includes taxes.

You write the check in plain language and Rex works out where the answer lives. If it needs a document, Rex says it is waiting on a deep dive rather than guessing.

Answers keep pace with the review. Every check is answered again after each deep dive, so if a document changes the answer, Rex updates it and marks it as changed rather than leaving a stale read on the page. Evidence from your first deep dive still counts when Rex re-answers after your fifth.

Rex reports the answers in their own section, one answer per check, so you can see exactly what each one turned up rather than hunting for it in a wall of text. Company administrators control the list, since these shape the analysis the whole team reads.

Can our team members work on the same bid package together?

Yes. You can add your own company teammates to a bid package at any point: while bids are open, right after award, or when you are deep into kickoff. Bring the right people in when you need them.

Multiple teammates can sit on the same bid package. Each person you add sees that bid package on their own dashboard. Everyone uses their own login. No shared passwords.

That is people from your own company. Who you invite to bid is a different block: invite lists, email invites, and whether the bid package stays private. In the dash that invite block is labeled Crew Control, so the names are easy to mix. It is not your own crew.

Estimating and procurement can hand off cleanly, or you can line up teammates before award and expand the team after, so Kickoff starts with everyone who needs to be in the room.

Can I organize multiple bid packages under one project?

Yes. KNTRCTR lets you group related bid packages into a project so a site, phase, or contract does not turn into a pile of disconnected requests.

For example, you might post separate bid packages for excavation, trucking, utilities, and concrete, then group them under the same project on your dashboard. Rex Build can draft those packages from the drawings, budget, and notes before you invite anyone. That gives your team a cleaner view of who priced what, who was awarded, and who was on site.

It also keeps the history documented for the future. If you ever need to look back at a site, you can return to that project and see the bid packages tied to the work instead of opening every package one by one.
