What makes a T&M contractor worth hiring?
"Time and materials" makes a lot of developers flinch on civil and renewable-energy site work. The important distinction is whether T&M is being used for planned, variable work or to recover from preventable mistakes — and lumping the two together is how good contractors get treated like a risk. So let's separate them.
The phrase "T&M" carries an unfair implication: that somebody, somewhere, went wrong. Sometimes that's true. Often it isn't. The problem is that the industry uses one term for two completely different situations, and a developer who can't distinguish them ends up suspicious of every contractor who mentions it. They almost need different names.
Type one: corrective T&M
This is corrective support after a site has already gone sideways. Prior work failed, a compliance issue surfaced with DEQ, or stormwater controls did not hold, and the site is failing. The original grant or bulk funding is gone, so the work gets billed at T&M rates, and the developer needs someone who can walk onto a troubled site and fix it.
Here, price isn't really the question. The developer is evaluating experience, ability, and the capacity to man the job fast. What makes a contractor worth hiring for corrective work is foresight: the ability to trace the logical flow of the project and pinpoint exactly what went wrong, where, and why. That diagnostic instinct is the whole value. It's also what keeps our own jobs from needing it.
Corrective T&M is a rescue. Fair T&M is a relationship. Treating them as the same thing does both a disservice.
Type two: fair, expected T&M
This is the normal kind: the close-out and cap work that's written into the contract from the start. A following trade (mechanical, electrical) damages finished work, weather does its thing, something happens through no fault of the contractor who already completed that scope. It gets billed T&M because that's what the contract says.
The contractor worth hiring here is the one who says: we'll bill T&M because it's in the contract, but we won't take advantage of you. We did our numbers right up front, so T&M isn't where we make our money. What the developer wants in this situation is the assurance that they'll be treated fairly. That's a commitment, and it's one you can make in writing.
Why the distinction matters to you
A contractor who leans hard on "a lot of T&M" can read two ways to a developer: trouble holding their own scopes, or a billing model that works against you. Neither is the message we want to send. The truth is that some corrective T&M shows up on nearly every project that's ever been scoped — that's the nature of complex civil work. What matters is character: fair, partnership-style T&M with the people you actually work with, and the competence to steady a site on the day it goes sideways.
If a contractor can explain the difference clearly and tell you which one your situation is, that's a good sign you've found one worth hiring.
