Our Story Since 1996
Founded as a woman-owned company with one crew and a simple belief — our legacy is what we create. Scroll through the milestones that made us who we are.
1996
Founded as a Woman-Owned Civil Constructor
Solid Earth Civil Constructors Inc. opens its doors with one crew, a few machines, and a belief that still drives us: our legacy is what we create.
2002
First Municipal Water & Sanitary Contract
We earn the trust of our first municipal partner — the start of decades of essential public infrastructure work across Colorado.
2009
Self-Perform Concrete Crew Established
Structural concrete comes in-house. Fewer hand-offs, more accountability, and one team responsible from excavation to finish.
2015
Technology-Forward, Fleet-Wide
3D machine control and GPS grading become standard across the fleet — precision in every layer, on every site.
2021
Contractor of the Year
Our crews’ craftsmanship earns industry recognition — and the award hangs where the whole team can see it.
2025
Regional HQ in Jefferson, CO
We build a home of our own in the high country. Woman-owned then, woman-owned now — and just getting started.
Friendly Faces to Know
No formal bios here. Hover or tap a face for a name, a role, and the kind of thing you’d learn in your first five minutes on site with them.
Dana Whitfield
Framed on her desk: the company’s very first paper timecard, from 1996.
Don Peters
Has walked every job site we’ve opened since 2003 — and remembers most of them by soil type.
Marcus Bell
Runs a spreadsheet for everything. Including his brisket smoke times.
Casey Lindholm
Can price concrete by the yard faster than you can open the calculator app.
Ray Gallagher
Thirty Colorado winters on site. Swears the cold keeps him young.
Miguel Serrano
Runs his crew in English and Spanish — and wins the jobsite chili cook-off every fall.
Sam Rowe
1,200 days without a lost-time incident on her watch — and counting.
T.J. Boone
Sets finish grade within a quarter inch. Claims he could do it blindfolded. We won’t let him.
Numbers Worth Bragging About (a Little)
Certified, Recognized, Trusted
Credentials don’t pour concrete — but they tell you who you’re working with.
