Detroit's Construction Boom Is Real — and the Insurance to Land the Big Jobs Just Got Harder

The boom is real — but it’s not everywhere

Let’s be straight about the market, because it’s uneven. Nationally, private commercial building actually softened a little this year. But Michigan is a standout: the state added about 10,400 construction jobs in the past year, and the work that is booming is the big stuff — infrastructure, power, and data centers. A single Michigan data-center campus announced for this year is expected to create more than 2,500 construction jobs on its own. Add the $350M I-94 reconstruction, the $70M Michigan Avenue rebuild in Corktown, the Michigan Central transit hub, the $250M U-M Center for Innovation, and the Hudson’s tower and JW Marriott racing to open before the 2027 Men’s Final Four — and metro Detroit has more than $420 million in projects lined up for 2026 alone. The opportunity is in the large, marquee jobs. And large, marquee jobs come with large, non-negotiable insurance requirements.

Big jobs come with big insurance requirements

Before a general contractor or project owner lets you on one of these sites, they’ll want proof you carry real coverage — and the bar is higher than it used to be. On a major project that usually means:

High general-liability limits, often with the specific additional-insured and completed-operations wording the contract dictates. Excess / umbrella limits stacked well into the millions, because one serious jobsite injury can trigger the kind of lawsuit we covered in nuclear verdicts. Builders risk sized to the full, current replacement cost of the project. Workers’ compensation that meets Michigan’s rules for your crew. Commercial auto for the trucks and equipment hauling to the site. Often contractors’ pollution and professional / design coverage on bigger or design-build work. And frequently surety bonds — bid, performance, and payment — which lenders and public owners require. Miss one requirement and you don’t just pay more; you can lose the job to the contractor whose paperwork was ready.

Why the coverage got harder in 2026

Here’s the part catching contractors off guard. The insurance market this year is two-speed: some coverage has actually eased, but the pieces that matter most for big projects have not. Excess and umbrella — the high liability limits large jobs require — are running up roughly 5% to 30% for construction in 2026, and they’re genuinely hard to assemble. Large firms that once stacked a $50–100 million limit with three or four insurers now need eight to twelve to reach the same number, each layer priced higher than it would have been a few years ago. General liability is running flat to up about 10%. And builders risk keeps climbing simply because construction costs do — you have to insure to full replacement value, and that number won’t sit still. The forces behind it — runaway jury verdicts, weather losses, material inflation, and outside money funding lawsuits — aren’t reversing.

Your insurance program is now part of winning the bid

When limits are this hard to source, your coverage stops being back-office paperwork and becomes part of whether you can bid at all. The contractors who win the big Detroit jobs line up their program early — before the bid, not the week work starts — and work with a broker who can actually reach the many carriers it now takes to build high limits. As an independent broker, that’s our job: we read the contract’s insurance requirements line by line, assemble the general-liability, excess, builders-risk, auto, and workers’-comp pieces into one program that meets them, line up the additional-insured and bonding paperwork owners ask for, and make sure you’re not over-buying limits you don’t need. The goal is simple — your insurance should never be the reason you lose a job you could have had.

The bottom line

Detroit is building its biggest projects in a generation right now, and the contractors who capture that work treat insurance as a competitive advantage, not an afterthought. Get your program reviewed before your next big bid — so when the requirements land, you can say yes the same day.
