Rex AI for primes
Meet Rex AI.He's read the bids. Have you?
Rex AI is the assistant on your tender page. Before you award, he has already compared the field, flagged what is missing, and pulled the attachment evidence, so your team can decide with a clearer map of the bid field.
Stage 1 · Quick scan
Six bids. Three scopes.Who actually covered it?
Rex AI scans the full field in under a minute: price outliers, missing responses, budget gaps, and your past reviews with each sub. No attachment deep-dive. No winner pick.
- Average, median, and spread across the field, so an outlier is obvious before you open a single PDF.
- One field scan card per company. Scroll the field, and each card opens up into past performance, how their price stacks up, and the notes to raise before you call them.
- Hit Dig Deeper on any company and Rex AI moves that one to Stage 2.
Where Rex AI lands: a map of the field. Not a recommendation.

What I'm Seeing
UpdatedBids:Avg $178,117Median $176,400Spread $21,550
Harbour Utilities came in the tightest at $168,200 while Riverside Civil is the highest bid at $189,750.
Direction is still pointing the same way after 1 of 3 deep dives completed; Harbour Utilities has not yet been reviewed.
The evidence so far still points toward Harbour Utilities as the candidate to examine first, based on lowest price at $168,200. Mobilization looks left out of that total. The completed deep dive on Riverside Civil confirms their $189,750 bid is complete and well documented, but the premium over the rest of the field is real.

Past Performance Snapshot
Always updating. Those summary tabs at the top, What I'm Seeing, Your Bid Expectations, Next Actions and the rest, do not sit still. Every deep dive you run feeds back into them, and anything Rex AI rewrites gets marked Updated so your team can see what changed.
Stage 2 · Deep dive
Lowest number looks clean.Is it?
Dig into one bidder. Rex AI reads the attachments, checks scope alignment, and pulls your history with them, conditions buried on page four included.
- Tells you what it actually read: how many attachments, how many past jobs, how many of your own reviews.
- Splits the read into scope alignment, reliability, and commercial signal, so you can go straight to the part you care about.
- Ends on a final take that lays out the trade-off and then hands the call back to you.
Where Rex AI lands: evidence. Still your call.

Additional context from past jobs
Scope Alignment
All four quoted items map directly to the tender requirements: FDOT Type F curb and gutter at 9,200 LF, concrete sidewalk at 42,000 SF, 24 ADA ramps with detectable warning panels included in the unit price, and a lump-sum mobilization.
The only exclusion noted is premium time unless directed by Williams. That is a standard carve-out but worth keeping in mind if the schedule compresses.

What you could do next
My final take...
Chevron is the most complete submission in the field and the scope alignment is clean. The price is above both the field average and your budget, with mobilization being the least explained line. The safety observation from a prior job is a conversation to have, not a disqualifier.
The decision on whether the execution profile justifies the premium over the field is yours. Message me in the chat if you want to work through the comparison against the other bidders.
Rex is for analysis only, all decisions are yours.
Bid expectations
They skipped the form.The quote is still in the PDF.
Bid expectations only work if the answers come back. Some subs will not fill them on platform. Some will email a quote and leave the rows blank. Rex AI can read that attachment and fill the prime's expectation responses so Harbour St still has a complete comparison row.
- Works when the sub left an expectation blank, and when you entered a manual bid from an emailed quote.
- Each line picks Bidder submission or Rex's findings. Keep what they typed on one row. Use the PDF fill on the next. The original stays visible.
- Parker Civil still decides. Filling a blank is not awarding the job.

AI Checks
Tell Rex AI what you want him to review.Standing questions, every job.
Every shop has its own scar tissue. The exclusion a sub buried that turned into a change order. The quote that showed up without taxes. The scope gap your trade always gets caught on. AI Checks are standing questions your company sets once, and Rex AI answers them on every job, in their own tab, one answer per check.
- Set once, answered every time. Your checks ride along on every job, so nobody has to remember to ask.
- Field-wide or document-deep. Point a check at the whole bid field, or at one bidder's documents during a deep dive.
- Answers keep pace. A field-wide check gets revisited after every deep dive. If a document changes the answer, Rex AI updates it and marks it changed instead of leaving a stale read on the page.
- On top of the analysis, not instead of it. Rex AI writes the analysis first, then answers your checks against it. A check cannot quietly reshape the findings your team relies on, and the usual limits still hold: no naming a winner, no leaving out evidence it found.
Company administrators own the list, since these shape the analysis the whole team reads. How AI Checks work

Williams' AI Checks
Standing questions your company administrators set in Settings under Rex AI. I answer each one separately, and I answer them after the analysis above is written, so a check cannot bend my other findings. A deep dive has changed at least one answer below.
Field scan checks
Answered across the whole field, then revisited after each deep dive in case a document changes the answer.
Does every bid include applicable taxes in the total?
AnsweredFour of five confirm taxes are in the total. Bidder D shows tax excluded on the equipment line, so their number is not comparable to the rest as submitted.
Flag any bid that excludes traffic control.
UpdatedAnsweredBidder B answered "included" on the bid form, but their conditions letter excludes lane closures after hours. That is a change from my earlier answer, which read the bid form only.
Has anyone capped their liability below our contract minimum?
Needs a deep diveNothing in the bid responses settles this. Caps like this live in the terms attachment, and Bidders A, C, D and E have not been deep dived yet.
Deep dive checks
These read attachments, so I answer them once per company you deep dive. 1 of 5 bidders done so far.
Confirm dewatering sits with the sub, not us.
Bidder B
Their scope letter puts dewatering with the general contractor, not with them. Priced accordingly, so the exclusion is real.
AnsweredFour bidders still to go. Run a deep dive and I will answer this against their documents too.

Harbour St watermainWhy is Harbour Utilities so much lower than the others?
Rex AI
Harbour Utilities came in at $168,200. Northline Excavating is at $176,400. The low number left Mobilization out of the total. After you fill that line from the quote, the gap is mostly the exclusion, not a cheaper crew. Worth confirming what is actually in scope before that number does any heavy lifting.
Have we used them before?
Rex AI
You have one completed job with them on record, rated 3.6 / 5. Timeliness and scope alignment both scored low. Not a red flag on its own, but I would not let price carry the decision when the history is that thin.
Performance memory
Price is the start of the conversation.The record is the rest.
Rex AI puts price in context, then checks the rest. Your own review history, market context where it exists, and what the attachments actually say. Award the job on the full picture.
Market context, kept anonymous
Published reviews from other companies round out the picture. Aggregate themes and scores only. Rex AI never names a job or client that is not yours to name.
Honest when history is thin
If Rex AI does not have enough to form a view, he says so. Fabricated confidence is worse than a gap. You will know when the signal is limited.
FAQ
How primes use Rex AI.
What happens in Stage 1 (Quick Scan)?
Stage 1 scans the full bid field and quickly surfaces outliers, missing responses, provisional/conditional amount signals, and early watch-list signals.
It is designed to answer: what needs attention first before your team dives into bidder-level detail.
What happens in Stage 2 (Deep Dive)?
Stage 2 analyzes one bidder in depth, including scope alignment, attachment evidence, commercial signal (including unit pricing and provisional amounts when present), and reliability context.
It is designed to answer: what is this bidder's risk/reward profile before award.
What is Rex Chat and when should I use it?
Rex Chat is a tender-scoped assistant for follow-up questions after Stage 1 and Stage 2.
Use it to pressure-test assumptions, ask specific bidder comparisons, and get focused next-step guidance without leaving the tender context.
Does Rex read attachments?
Yes. In deep-dive workflows, Rex can analyze supported attachment content and include relevant findings in the bidder-level review.

Does Rex replace estimators or project managers?
No. Rex is an assistant for structured analysis, not an autopilot that awards work.
Your team remains accountable for final decisions, trade-offs, and commercial judgment.
