Read Insurance Requirements Exhibit Before Bid

🎯 To read an insurance requirements exhibit before you bid, work three columns in this order: limits, endorsements, and mechanics. Confirm the required general liability limit (usually $1M per occurrence / $2M aggregate on commercial subcontracts), then check for the three endorsements that actually cost money to add — additional insured (CG 20 10 + CG 20 37), primary and non-contributory, and waiver of subrogation. If the exhibit demands endorsements your current policy does not carry, price the delta before you sign, because those endorsements can add 5% to 15% to your premium.

TL;DR

• The exhibit has 3 layers that matter: limits, endorsements, mechanics. Read them in that order, every time.
• The 3 endorsements that trigger a premium change or a policy switch: additional insured (CG 20 10 / CG 20 37), primary and non-contributory, waiver of subrogation.
• A certificate of insurance (COI) proves nothing about additional insured status — only the endorsement does. GCs and their compliance portals reject COIs for exactly this reason.
• Don't commit to anything until your licensed agent reviews the exhipt against your actual policy. Reading the exhibit yourself is a screening step, not a substitute for professional coverage review — this guide helps you ask the right questions, not skip the agent.

Methodology

This guide is built from publicly available ISO/ACORD form conventions and standard commercial-subcontract insurance language as of August 2026. Endorsement form numbers (CG 20 10, CG 20 37) and limit conventions are cross-checked against ACORD certificate standards and ISO Commercial General Liability forms. Dollar limits reflect common 2026 commercial-subcontract requirements and vary by GC, project size, and jurisdiction — treat them as typical, not universal. Nothing here is legal or insurance advice; confirm every figure with your broker before signing.

What is an insurance requirements exhibit?

An insurance requirements exhibit is the schedule attached to a subcontract or bid packet that lists the coverage you must carry, the limits, and the exact endorsements the general contractor (GC) requires before you can perform work. It is usually labeled "Exhibit C," "Insurance Requirements," or "Insurance Specifications," and it is where 4 out of 5 COI rejections originate.

The exhibit is the contract. The COI is just evidence you tried to meet it. When those two documents disagree, the GC withholds payment, and you are the one chasing your agent at 5pm on a Friday.

How do I read an insurance requirements exhibit before I bid?

Read it in 3 passes, and price each pass before you commit. Do not read top to bottom — read by what costs you money. This is the workflow. One input (the exhibit PDF), a series of outputs (a go / fix / no-go decision).

Input: the insurance requirements page in the bid packet (PDF or portal screenshot). Output: one of three answers — you can sign this · you can sign it once you fix two things · don't sign this yet.

Pass 1 — Limits (2 minutes)

Find every dollar figure and match it against what your policy carries today.

If any required limit exceeds what you carry, that is a mid-term policy change or an umbrella purchase — flag it and price it before you go to Pass 2.

Pass 2 — Endorsements (the money pass)

Limits are usually cheap to adjust. Endorsements are where the premium moves. These are the three that reliably trigger a cost or a policy switch:

1. Additional insured — CG 20 10 (ongoing operations) and CG 20 37 (completed operations). Most GCs require both. The COI checkbox for "additional insured" means nothing without the attached endorsement forms. Portals like the major compliance vendors reject on this daily.
2. Primary and non-contributory. This puts your policy first and prevents your insurer from sharing the loss with the GC's insurer. Often bundled with the AI endorsement, sometimes priced separately.
3. Waiver of subrogation. Bars your insurer from recovering against the GC after paying a claim. Carriers charge for giving up that right.

Together, these can add roughly 5% to 15% to your premium depending on carrier, class code, and project. If the exhibit demands any of them and your policy doesn't already carry them, that is your "fix two things" or "don't sign yet" answer — and the number you need your agent to quote before the bid.

Pass 3 — Mechanics (the fine print that voids the deal)

• Notice of cancellation language (often 30 days).
• Additional insured scheduling — blanket vs. per-project endorsement.
• Certificate holder wording — exact legal entity names for the GC and any owner.
• Submission deadline — some portals require compliant COIs before you can even sign.

Mechanics rarely change your premium, but they routinely delay your first payment. Read them so the paperwork clears the first time.

Why a COI is not proof of coverage

A certificate of insurance is a snapshot summary issued for convenience — the ACORD 25 form itself states it "confers no rights upon the certificate holder" and "does not amend, extend or alter the coverage." Only the actual endorsement forms attached to your policy grant additional insured status. This is exactly why GC compliance portals ask for endorsement copies, not just the COI.

How to price the delta before you bid

1. Run your own 3-pass read using the tables above and mark each required item as have / don't have.
2. Send the exhibit PDF to your licensed insurance agent or broker and ask for a written quote on any missing endorsement or limit increase. Ask them to review the ACORD forms directly.
3. Fold that delta into your bid number — not after you win.

Do not sign or price the job without your agent's review. You are screening for cost drivers; your broker confirms what your policy actually delivers and what the change will cost.
