Considering a Career in Preconstruction & Estimating? Here’s What I Wish I’d Known as a Student.

By: Andrew Bisbee, Principal | Preconstruction & Estimating

When I was in school, I didn’t set out to become an estimator.

Like a lot of students interested in construction, I thought the path was pretty linear and being a project manager was the ultimate goal. Preconstruction and estimating weren’t roles anyone was really talking about, and I certainly didn’t hear many people say, “I can’t wait to graduate so I can be an estimator.”

I stumbled into it through a co‑op in the mid‑1990s. My desk was literally in the copy room. What I didn’t realize at the time was that I had found a role that would keep me challenged, learning, and engaged for more than 30 years.

If you’re a student considering a career in construction, or trying to figure out where you fit, here are a few things worth knowing about preconstruction and estimating.

You Still Have to Know How to Build the Building

One of the biggest misconceptions about estimating is that it’s just spreadsheets and takeoffs.

In reality, good preconstruction requires you to understand how a building actually comes together. You’re mentally building the project long before anyone steps on site, thinking through logistics, sequencing, constructability, and risk.

The best estimators aren’t guessing. They’re asking:

• How will this actually be built?
• Where could this go sideways?
• What assumptions need to be tested early?

If you enjoy thinking through problems and understanding how things work, a job in preconstruction and estimating can be incredibly rewarding.

It’s Fast‑Paced, Varied, and Constantly Evolving

In preconstruction, no two days are the same.

You might work through multiple projects in a single week, across different building types, design phases, and client goals. That pace means you learn quickly and continuously.

Early in my career, I gravitated toward estimating because of that exposure. You touch so many parts of a project so often that your learning curve accelerates. You see patterns. You build judgment. You start to understand why certain decisions matter later in construction.

And as technology evolves, from databases to 3D modeling to AI, the role keeps changing. That’s a good thing. It means there’s always room to improve how the work gets done.

An Estimate Is More Than a Number

This is one of the most important lessons I’ve learned.

An estimate isn’t just a price; it’s a commitment. Projects move forward, land gets purchased, and designs advance based on the numbers produced during preconstruction.

That responsibility forces you to think carefully, ask good questions, and stand behind your work. You’re not just reacting to drawings; you’re helping shape decisions.

When done well, preconstruction can:

• Reduce surprises later
• Improve collaboration with design teams
• Build trust with owners and developers
• Set projects up for smoother execution

That kind of impact is easy to overlook when you’re a student—but it matters.

You Don’t Have to Love the Spotlight to Have Impact

Not everyone wants to run a jobsite or manage day‑to‑day construction. Preconstruction offers a different kind of ownership.

You may not be the one physically building the project, but you play a critical role in whether it succeeds. I still feel connected to every job I’ve worked on, because the decisions made early often shape everything that follows.

There’s real satisfaction in seeing a finished project and knowing you helped guide it from the very beginning.

If You’re Curious, Try It

If any of this sounds interesting, my advice is simple: get exposure.

Look for co‑ops, internships, or early roles that let you spend time in preconstruction or estimating. Talk to people doing the work. Ask questions. See if you enjoy the problem‑solving and pace.

This career path isn’t always obvious, but for the right person, it’s challenging, meaningful, and deeply rewarding.

I didn’t plan to spend my career in preconstruction. But looking back, I wouldn’t change a thing.
