what comes out

From thousands of pages to what your team needs to bid.

Not a summary. A structured review of what the tender requires, what needs to be priced, what needs clarification and what could become a problem later.

/01

Requirements

Mandatory conditions, eligibility criteria, experience, personnel, certifications, forms and deadlines.

Know what you must comply with
/02

Contractual risk

Penalties, guarantees, liabilities, termination clauses and contradictions between documents.

Know what you are agreeing to
/03

Operational risk

What the tender requires versus what can actually be delivered: schedule, permits, staffing, equipment and site conditions.

Know what could hurt during execution
/04

Pricing inputs & gaps

Quantities, specifications, volumes, staffing, service levels and anything else your team needs to price. If something is missing, it is surfaced as a question instead of an assumption.

Price what is known. Clarify what is not.
your context

Not just what the tender says. What it means for your business.

The review can incorporate the knowledge your company already has: previous tenders, operating experience, decision rules, recurring risks and the way your team prices and delivers work.

The same clause does not mean the same thing to every company.

Requirements

Checked against what your company can and wants to deliver.

Contractual risk

Evaluated against the risks your business is willing to accept.

Operational risk

Compared with what your team has learned from actually doing the work.

Pricing

Structured around the way your team prepares a bid.

what gets missed

Some lines take 20 seconds to understand and three days to find.

None of them is difficult once someone points to it. The hard part is finding it across twenty documents and thousands of pages.

bond

The bid bond is a fixed amount, not a percentage.

Administrative Terms · p. 34 · art. 12.3
penalty

Daily delay penalty with no stated cap.

Administrative Terms · p. 58 · art. 22.4
contradiction

A clarification changed the deadline. The annex still shows the old one.

Clarification No. 2 · p. 3 · resp. consulta 17
permit

The required permit takes longer than the mobilization window.

Technical Terms · p. 92 · art. 9.5

This is why the whole package has to be reviewed, not just summarized.

Risks & requirements

#severityrequirement or riskdocumentpage
Administrative Terms · p. 34 · art. 12.3
"The bidder shall submit a bid bond in the amount of $420,000, issued in favor of the owner, valid for a minimum of 120 calendar days from the bid opening date."
why it matters

The fixed amount is nearly double the 3% of contract value the company budgets by habit, and the validity period forces renewing the bond if the award slips. Submitting the usual amount puts the offer out at opening, with no chance to fix it.

Administrative Terms · p. 41 · art. 15.1 b)
"The bidder must evidence execution, as prime contractor, of at least two storm-water collector projects with a pipe diameter of 40 inches or greater, formally accepted within the last five years."
why it matters

Two conditions read fast and disqualify: "prime contractor" rules out work done as a subcontract, and "formally accepted" rules out work finished without a certificate. That drops the usable track record from four works to one.

Administrative Terms · p. 58 · art. 22.4
"For each calendar day of delay in delivering the stated milestones, liquidated damages of $1,500 shall apply, deducted from the next progress payment."
why it matters

The article sets no cap and nothing else in the terms limits it: a two-month delay on a single milestone eats the entire contract margin. Liquidated damages also run on calendar days, so weekends and holidays count.

Technical Terms · p. 77 · art. 6.2
"The site manager shall remain on site throughout the working day, dedicated exclusively to this work, and may not perform duties on other contracts of the same bidder."
why it matters

The company splits two site managers across three works. Complying means hiring another for the whole contract, a direct cost that rarely reaches the bid sheet because the requirement sits in the technical terms, not the administrative ones.

Every row cites document, page and clause. No source, no row.

steel pipe
"Steel pipe shall have an interior epoxy lining suitable for potable water, at the thickness specified by the manufacturer."

The spec gives neither thickness nor area to be lined. The line item stays open as a question for the buyer: the quantity is not invented to fill the sheet.

"Furnish carbon steel pipe, 12 in nominal diameter, 0.250 in wall thickness, for the discharge line."
hdpe pipe
"Excavation shall provide a minimum cover of 3.5 ft over the crown of the HDPE pipe."
trench excavation
"Any over-excavation shall be backfilled with 2,000 psi lean concrete."
concrete works
"Chambers shall be constructed of 4,000 psi concrete, with a 90% confidence level."
"Rebar cover shall be as shown on the corresponding detail drawings."

The spec defers the value to detail drawings that are not in the published package. It stays a question to ask before taking off the rebar.

what is missing

We do not guess what is missing.

Every gap becomes a question for the buyer.

If a specification refers to a quantity, drawing, dimension or condition that is not actually included in the tender package, the system does not complete it from context.

It stays missing until someone answers it.

why not a chat

A chat helps you read the tender. This checks it.

The difference is not the model. It is the review process around it.

how it works

We don't read less. We read differently.

The entire tender goes in. Every finding is checked against the source. What is missing becomes a question.

Ten minutes sounds like magic? That is what happens when dozens of agents read your documents at the same time. And none of them can assert anything it cannot point at.

/01

The entire package goes in.

Terms, annexes, drawings, clarifications and Q&A, exactly as received.

/02

We look for obligations, risks and contradictions.

Not just summaries: what is required, what affects pricing, what conflicts and what needs clarification. Every page is anchored to document, page and clause, which is what later lets you jump back to the evidence in one click.

/03

Every finding is checked against the source.

What cannot be verified is not presented as fact. If the terms are ambiguous, it comes out as a question to ask the buyer, not as a finding.

No source, no finding.

We do not send you AI output.

We review the analysis before it reaches your team.

We check that the findings are supported by the documents, that the questions are relevant, and that the risks make sense for how your company bids and delivers. The report arrives ready for the bid/no-bid meeting: every line can be opened, verified and argued against the original document.

The system does the reading. We take responsibility for what reaches you.

The system review takes minutes. Your reviewed report arrives the same day.
