What We Do

Small company attention. Big contractor experience.

We’re the first phase of every project. Phase One self-performs the demolition and site work that lay the groundwork, and as a licensed Florida general contractor we carry the job through renovations, additions, and new construction.

01

Demolition

Selective interior demolition, full structure tear-down, and clean, contained demolition in occupied and sensitive spaces. We plan, contain, and document every job — no surprises in the dust.

Healthcare & Occupied Facilities

Renovations, demolition, and infrastructure work inside operating hospitals, medical offices, and occupied buildings. ICRA containment, negative air, interim life safety, and after-hours shutdowns — planned with facilities, not around them.

Site Improvement

Grading, hardscape, drainage, utility prep, and site readiness across Palm Beach and the Treasure Coast. The unglamorous work that determines whether everything above it goes well.

Who We Are

Built by superintendents.

Phase One was founded by two former superintendents who spent years running healthcare and commercial jobs for one of South Florida's premier general contractors. Together they've helped deliver more than $470M in complex healthcare construction, leading field operations on projects that peaked at 300+ workers on site. We started Phase One so every project gets an owner on it, every day, and the same attention to detail a hospital demands.

At Phase One, our success depends on yours. As a growing company, every project strengthens our reputation. We take on fewer jobs and stake our name on every one — because in this business, the last project you finished is the only reference that counts.

Owner-Led, Always

No project is handed off. An owner is on every job — that's the whole point of starting a small shop.

Schedule-Obsessed

Healthcare clients don't tolerate float. That discipline carries into every commercial project we touch.

Small Shop, Big Standards

You won't be filler here. Every project gets the same focus regardless of contract value.
