Bringing Ownership and Expertise to Every Job Site.
Commercial construction projects aren’t just about concrete and asphalt. They’re coordination, communication, and protecting your tenants’ experience.
Diversified was built specifically around those priorities, and for more than 50 years we’ve partnered with property managers, facility teams, and owners to deliver projects that are organized, predictable, and low-stress.
Our Process
Our leadership and field teams bring decades of property-management experience, so we understand exactly what matters on your side of the table.
We scope every project according to actual site conditions, not just plans and specs.
Before pricing large mill-and-fill projects, our crews perform no-cost pavement core samples and field verification to confirm actual conditions.
Most contractors hand over a phase map and leave the rest of you. We take ownership of the coordination.
Our team handles conversations and planning before work even begins, giving you and your property managers peace of mind.
Our self-performing crews handle both asphalt and concrete work, along with excavation and restoration.
That means no juggling multiple vendors, or finger-pointing between trades. Just tighter schedules and better quality control.
