Having sat on both sides of the vendor onboarding table — as a CFO of a specialty sub submitting prequals, and then as the approver of prequals on the GC side — I can tell you the uncomfortable truth. A thick, glossy prequal binder with a 40-page capability statement is usually read backwards. The reviewer flips to the financial statement, checks three numbers, pulls the EMR, cross-references the bond letter, and forms an opinion in under nine minutes. Everything else in the package is there to not contradict those nine minutes.
If you want to move from "submitted" to "approved and on the bid list," you need to understand what the reviewer is looking for and submit it in a form they can evaluate quickly. What follows is a mechanical, trade-press-grade walkthrough of the documents and numbers that actually move the decision.
Which form is being used, and why it matters
Prequalification forms come in three dominant flavors. They ask for the same underlying data but the emphasis differs.
| Form | Publisher | Emphasis |
|---|---|---|
| AIA A305-2020 | American Institute of Architects | Financial statements, bonding, experience list, key personnel resumes |
| ConsensusDocs 221 | ConsensusDocs coalition (AGC, 40+ associations) | Subcontractor-specific prequal, safety (EMR, OSHA 300A), insurance, financial |
| GC-specific (Turner TCC, Skanska, DPR, etc.) | Proprietary | Combines A305 financial depth with ConsensusDocs safety rigor, adds diversity/ESG and project-specific scope |
The AIA A305 was substantially revised in 2020 to tighten financial-statement requirements — auditors' reports must now be less than 18 months old and must be prepared under US GAAP. ConsensusDocs 221 places more weight on the safety record and insurance data. The proprietary GC forms pull from both and then add proprietary questions about the named PM's prior project list, bonding exclusions, and subcontractor default history.
The four data points that actually drive approval
1. Single-project and aggregate bonding capacity
The single most-read number in the entire submittal. Two figures: single-project capacity (the largest project your surety will bond) and aggregate capacity (total open bonded work they will support). The industry rule of thumb, still approximately valid in 2026: aggregate bonding capacity is 10 to 20 times working capital, with 10x being conservative and 20x being aggressive. Sureties underwrite to working capital and net worth; GCs read the bond letter as shorthand for both.
What reviewers look for: your single-project capacity should be at least 1.5x the value of the job they might award you. If you are being considered for a $4M scope and your single is $5M, that is fine. If your single is $4.1M, that is a flag because the surety is already stretched. If the surety letter is silent on aggregate, reviewers read that as the surety being unwilling to commit to a number.
2. Financial strength and liquidity
The reviewer opens your CPA-audited or CPA-reviewed financial statement to the balance sheet and computes three ratios in their head: current ratio (current assets / current liabilities — should be above 1.3), debt-to-equity (total liabilities / equity — should be under 3.0), and working capital (current assets minus current liabilities — should be at least 10% of annual revenue). If your financials are compiled only (not reviewed or audited), knock yourself down one tier before the reviewer even opens the file.
The Dun & Bradstreet PAYDEX score is the secondary credit signal. PAYDEX is scored 1-100 and reflects how promptly you pay your vendors. A PAYDEX of 80 means you pay on time. Below 70 is a flag. Below 60, the reviewer will want an explanation. It is also worth pulling an Experian Business Credit report alongside PAYDEX — Experian weights trade lines differently, and reviewers at larger GCs will pull both. If your payment history looks cleaner on one than the other, submit both and let the stronger one set the framing.
3. EMR (Experience Modification Rate)
This is a workers' comp actuarial score published annually by NCCI (or independent bureaus in monopolistic states like Ohio and Washington). An EMR of 1.00 is the industry average. Below 1.00 means your claims experience is better than average; above 1.00 means worse. Most top-tier GCs set a cap of 1.00 or 1.05 for subcontractor prequalification. Some owner-direct contracts (federal, large industrial) set 0.90.
Pull your EMR letter directly from NCCI or your carrier and submit the unaltered document. EMRs are calculated on a three-year rolling window with a one-year lag, so the letter you submit in March 2026 reflects claims from 2022-2024. A recent claim year drops off each year; plan your prequal submissions around when a bad year ages out.
4. OSHA 300A and TRIR
The OSHA Form 300A is the annual summary of workplace injuries and illnesses, which all employers with more than 10 employees must post by February 1 each year. Reviewers read the totals and compute your TRIR (Total Recordable Incident Rate) as: TRIR = (recordable incidents x 200,000) / total labor hours worked. The 200,000 represents 100 workers working 40 hours/week for 50 weeks. The BLS industry average TRIR for specialty trade contractors is approximately 2.5; top-quartile GCs expect under 1.5, federal and heavy industrial work often requires under 1.0.
Submitting only the current year's 300A. Reviewers want three years of 300As so they can see the trend. A single-year 300A with zero recordables looks suspicious; three years showing incident reductions tells the story you want told.
The three documents that get skimmed
These matter, but only as pattern checks rather than as content the reviewer reads line-by-line.
- Completed project list (WRAP schedule) — a table of the last 3-5 years of completed projects, with owner, GC, scope value, completion date, and reference contact. Reviewers scan for project size range, repeat owners, and whether the references are on projects similar to the one being bid.
- Key personnel resumes — PM, superintendent, project executive, and (for subs) lead foreman. Reviewers check that the people named are still on payroll. Proprietary GC forms increasingly ask for named individuals on the specific bid, not a generic company bench.
- Insurance certificate summary — GL ($2M aggregate minimum, often $5M), umbrella ($5M-$25M depending on project scale), auto, workers' comp, and professional if design-build. Reviewers confirm limits meet the GC's subcontract requirements and check the carrier rating (A.M. Best A- or better is standard).
CCIP vs. OCIP and how it changes the conversation
When a project is under a wrap-up policy — a CCIP (Contractor-Controlled Insurance Program) or OCIP (Owner-Controlled Insurance Program) — most of the subcontractor's GL, workers' comp, and often umbrella coverages are replaced by the wrap. This changes prequal in two ways:
First, the GC needs to see that you can continue to maintain off-site insurance (the wrap typically only covers on-site operations). Second, the GC adds a credit for the insurance cost the wrap covers; you need to submit an uninsured-bid breakdown showing your normal insurance cost so the credit is calculable. Shops that submit a lump-sum bid and then try to calculate the wrap credit later almost always lose money on the credit.
CCIP and OCIP distinctions matter for claims administration too. Under CCIP, the GC is the sponsor and loss history accrues to the GC. Under OCIP, the owner is the sponsor. A sub who had a serious loss on an OCIP project may find it doesn't affect their own EMR as heavily, but may have a contractual loss-reporting obligation that gets referenced in future prequals.
The document checklist
A clean prequal submission in 2026 includes, in this order:
- Cover letter on your letterhead with company summary, revenue last three years, owner/founders
- Completed AIA A305 (or ConsensusDocs 221, or the GC's proprietary form) — all fields filled, no "N/A" in critical sections
- Three years of CPA-audited or reviewed financial statements with auditor's opinion
- Surety letter stating single-project and aggregate bonding capacity, dated within 60 days
- Current-year EMR letter from NCCI or carrier
- Three years of OSHA Form 300A summaries
- Insurance ACORD 25 sample with current limits (or wrap-up-ready uninsured-bid breakdown)
- D&B PAYDEX report (current, not older than 90 days)
- Completed project list — 3-5 years, minimum 8 projects, with contactable references
- Key personnel resumes — PM, superintendent, safety officer, foreman
- Written safety program table of contents (not the full 400-page manual)
- Diversity / ESG statement if required (MBE/WBE certificates, DBE filings)
- Litigation disclosure — three years, with disposition of each matter
"The prequal we approve on Tuesday morning is the one where the numbers are all on the first three pages. The one we table for the next review cycle is the one where we have to hunt for the bond letter."

Maintenance cadence
Treat prequalification as a living file. Update your EMR letter every January, refresh the surety letter every 90 days during active bidding, and pre-stage current-year financials in Q2 once your auditor signs them. A prequal that lives in a shared drive with dated filenames (prequal_2026Q1_full.pdf) is always ready to submit. A prequal that lives in an email thread is always six days out of date.
