Union Corner Construction was founded in 1981 and has built four decades of reputation in SW Washington commercial construction — the same values, sharpened by three generations of hands-on trade experience.
For most of its life, Union Corner did what good regional GCs do: built solid commercial work across SW Washington, paid its subs on time, and earned a reputation it didn't have to advertise. That reputation — and the sub relationships behind it — is the foundation everything here is built on.
Jeff, Ryan, and Marc Simonson lead the company today, bringing careers in commercial construction to a reputation four decades in the making. Their focus isn't changing what made Union Corner work — it's carrying the best of it forward, and modernizing the paper-and-spreadsheets backend that holds most GCs this size back.
So the relationships with subs the previous owner built are the same. The on-time-payment ethic is the same. What's new is the operations layer underneath — proprietary bidding software, an AI-first workflow, and a discipline about full-scope pricing that shows up in every proposal we send.
Construction runs three generations deep in this family. It's why the principals speak the language of the trades without performing it — they've worked them.
It started in the trades — the Simonson father running framing and drywall as a subcontractor. The values that show up in how we treat subs today were learned from the other side of that relationship.
The next generation built on it — Jeff starting his own construction business, the brothers eventually buying their father's company. Decades of running jobs, managing trades, and answering for the result.
Jeff, Ryan, and Marc bring 80+ combined years of field experience to a 44-year SW Washington institution — a reputation worth continuing, and a backend worth modernizing.
Not a team being managed from a distance. A team that has worked every level of a jobsite — and still does.
~30 years in commercial construction. Fluent in document hierarchy, delivery methods, and consultant coordination. Built BidPack because the existing tools didn't measure up. Usually the first person you'll talk to.
20+ years, having worked every trade level from laborer up. On-site through construction — the reason owners don't have to babysit the job themselves.
30+ years in the field. Assigned to the largest and most challenging projects, where experience is the difference between a schedule held and a schedule lost.
Marc Simonson leads the company alongside Jeff and Ryan.
A long-standing, stable sub list is an asset you can't buy in a hurry. We protect those relationships because reliable subs are what keep an owner's schedule intact.
The previous owner's strongest practice, and one we kept without a second thought. Subs who get paid on time are subs who show up — and stay engaged across the whole project.
We don't take a sub's number and beat them up with it. It's in our proposal package in writing — the same ethic, now stated out loud.
That's the conversation we start with. Tell us about the project — and the one before it. We'll tell you, honestly, whether we're the right builder for it.
