A 47-Page Contract, a $180,000 Mistake, and a Lesson Off the Dallas North Tollway

The MSA was forty-seven pages long. The electrical subcontractor — a solid ten-man crew based out of Frisco — flipped to the signature line, signed, and celebrated landing the biggest tenant build-out his company had ever won. Somewhere around page thirty-one, buried between the indemnification article and the termination clause, sat the insurance requirements: $5 million umbrella policy, additional insured endorsement on CG 20 10 and CG 20 37, waiver of subrogation on all lines, and primary-and-noncontributory language.

He had a $1 million GL policy. No umbrella. No endorsements. Three months later, a worker from a different trade fell through a temporary platform. The GC tendered the claim to our subcontractor under the MSA’s indemnity clause. His insurer denied defense — the additional insured endorsement had never been issued. The gap was $180,000 out of pocket. The job he “won” nearly bankrupted him.

This isn’t a hypothetical. It’s a pattern we see across the Frisco–McKinney–Prosper corridor every quarter as North Texas commercial construction accelerates. According to the International Risk Management Institute (IRMI), a master service agreement is a contract that specifies the terms and conditions governing all future work between two parties — and the insurance section is where hidden exposure lives. Here are the five questions every contractor must ask before signing one.

Question 1: “Does My Current Policy Actually Match What This MSA Requires?”

First principles: an MSA doesn’t create risk — it redistributes it. The insurance clause is the mechanism that determines which party’s policy absorbs the financial consequence of something going wrong. If the MSA demands $2 million per occurrence in general liability and your policy carries $1 million, you’ve just agreed to personally backstop the difference.

Before you sign, pull your declarations page and compare it — line by line — against the MSA’s insurance article. Look for these four things:

• Coverage types: Does the MSA require commercial general liability, commercial auto, workers’ compensation, inland marine coverage for tools and equipment, professional liability, or pollution liability? If you don’t carry it, you need it before you sign.
• Limit amounts: Many North Texas GCs now require $1M/$2M in GL, $1M in auto, and $5M+ in umbrella for commercial projects — especially along the US-380 and DNT corridor where project values are climbing.
• Policy form: Is your GL written on an occurrence vs. claims-made basis? Some MSAs specify one or the other — and the wrong form can leave years of exposure uncovered.
• Endorsements: Additional insured, waiver of subrogation, primary and noncontributory — these aren’t suggestions. If the MSA lists them, your policy must include them.

Think of it this way: signing an MSA without comparing your policy is like handing someone a blank check and hoping they never cash it. The MSA is the check. Your insurance is the account balance. If the balance doesn’t cover the check, you pay the difference personally.

Question 2: “Am I Listed as Additional Insured — or Just a Certificate Holder?”

This is the single most misunderstood distinction in commercial insurance — and it’s the one that burns contractors the hardest. We wrote an entire guide on certificates of insurance in Texas, but here’s the core truth stripped to its foundation:

A certificate holder receives a piece of paper proving your insurance exists. That’s all. They get no coverage, no defense rights, no claim access. A certificate holder is a spectator — they can see the game but can’t step on the field.

An additional insured is actually added to your policy. If a claim arises from your work, the additional insured can trigger your policy for defense and indemnity. They’re not a spectator — they have a working key to your coverage.

Most MSAs require the GC (and often the property owner) to be named as additional insured — not just a certificate holder. The standard endorsement forms are ISO CG 20 10 (for ongoing operations) and CG 20 37 (for completed operations). If the MSA requires both and your agent only issues the ACORD 25 certificate without actually endorsing the policy, the GC appears protected — but isn’t. And when the claim comes, the gap falls on you.

We’ve seen this exact scenario play out across North Texas. Read about the 7 COI mistakes costing Texas contractors jobs — it’s the most common reason subcontractors lose bids or face payment holds.

Question 3: “Does the MSA Require a Waiver of Subrogation — and Does My Policy Allow It?”

Here’s how subrogation works: after your insurer pays a claim, they have the legal right to pursue the party who actually caused the loss to recover their money. A waiver of subrogation is an agreement that your insurer will not exercise that right against a specific party — typically the GC or property owner named in the MSA.

Nearly every commercial MSA in Texas requires this waiver on all lines — general liability, auto, workers’ compensation, and umbrella. The problem? Most standard policies don’t include it automatically. It must be added as an endorsement. And if you contractually agree to waive subrogation but never actually endorse your policy, you’ve created a gap your insurer can use to deny coverage entirely.

Proverbs 22:3 says it plainly: “A prudent man foreseeth the evil, and hideth himself: but the simple pass on, and are punished.” The “evil” here isn’t the MSA itself — it’s signing the MSA without confirming your insurer will honor the promises you just made.

The fix is straightforward: send the MSA’s insurance article to your agent before you sign. At The Agent’s Office®, we review MSA insurance clauses for our commercial clients and confirm — in writing — that every required endorsement is in place before the certificate of insurance is issued. The typical cost to add a waiver of subrogation endorsement is $50–$250 — a fraction of the six-figure gap it prevents.

Question 4: “What Happens to My Coverage After the Job Is Done?”

This is where a lot of Texas contractors get blindsided. Your GL policy protects you during the job — that’s “ongoing operations.” But what about a claim that surfaces six months, two years, or five years after the project is complete?

That’s the domain of completed operations coverage — and many MSAs require you to maintain it for two to five years (sometimes longer) after the work is finished. Some MSAs in the North Texas market now require completed operations coverage extending through the full statute of repose, which in Texas can run up to ten years for construction defects.

This is why the policy form matters. An occurrence-based GL policy covers claims arising from work performed during the policy period, regardless of when the claim is filed. A claims-made policy only covers claims made during the policy period. If you let a claims-made policy lapse without tail coverage, everything you built last year becomes uninsured. For contractors in the Frisco–Prosper–Celina growth corridor taking on larger commercial jobs, understanding this distinction is not optional.

Question 5: “Who Pays If the Indemnity Clause Exceeds My Policy Limits?”

This is the question that separates contractors who survive from contractors who don’t. Most MSAs contain an indemnification article that says something like: “Contractor shall defend, indemnify, and hold harmless [GC/Owner] from and against all claims arising out of or related to Contractor’s work.”

Read that carefully. “Arising out of or related to” is extraordinarily broad. It can include claims where you weren’t even at fault — a worker from another trade injured on a platform you had nothing to do with, but the GC tenders it to you under the MSA because your crew was in the vicinity.

Your insurance is designed to fund your indemnity obligation. But insurance has limits. If the MSA’s indemnity clause is broader than what your policy covers — or if the claim exceeds your per-occurrence limit — you pay the difference. Not your insurer. You. Your business bank account, your equipment, your receivables.

This is where an umbrella policy becomes non-negotiable. The umbrella sits above your GL, auto, and employers’ liability, providing an additional layer of protection. For most subcontractors bidding on commercial work in North Texas, a $2M–$5M umbrella is now the cost of entry. According to the Texas Department of Insurance (TDI), contractors should verify that all endorsements — including waiver of subrogation — flow through to the umbrella layer as well.

The first principles truth: an MSA doesn’t just define the work — it defines who absorbs the financial shock when the work goes wrong. Insurance is the shock absorber. If the absorber is undersized for the load, the frame cracks. Your frame is your business.
