In-House Trade Expertise That Controls the Critical Path

Harris United’s mechanical, electrical, and plumbing capabilities give our clients greater control over schedule, cost, and quality. While many general contractors outsource nearly every trade, we retain 60+ in-house trades professionals on staff and provide leadership oversight for plumbing and mechanical systems. That structure strengthens coordination across projects and supports true MEP integration from early planning through final inspections.

  • Electrical Crews That Travel

    Our in-house electrical teams are licensed in 33+ states, preserving consistency in installation, sequencing, and safety. Electrical work often drives the critical path, and keeping this scope in-house allows us to respond quickly in the field and maintain momentum when timelines tighten.33

  • Sitework and Utilities Expertise

    Mechanical, electrical, and plumbing systems begin below grade, and early coordination with our sitework crews reduces conflicts later in construction. With four generations of earthwork experience, we’re able to evaluate soil conditions, understand regional differences, and know what jobs should cost.

  • Coordinated Plumbing and Mechanical Leadership

    Our experienced managers oversee plumbing and HVAC installation to ensure alignment with overall project sequencing. This leadership approach strengthens MEP integration and supports clear communication with local subcontractors.

Trade Expertise That Supports the Entire Program

Our teams regularly coordinate OFCI (Owner-Furnished, Contractor-Installed) components, aligning trade work with equipment provided by the owner. That includes planning around delivery timelines, ensuring proper rough-ins, and supporting seamless installation. Strong vendor coordination keeps owner-supplied equipment aligned with construction so projects never stall waiting on third-party deliveries—whether it’s a new build or a remodel.

Frequently Asked Questions

Underground utilities and soil conditions determine how mechanical, electrical, and plumbing systems are installed and protected. We evaluate soil variability, understand regional differences, and identify potential cost drivers early. That expertise reduces change orders and protects schedule performance before vertical construction begins.

When trades rotate from project to project, institutional knowledge is lost. Because our in-house teams travel, we identify recurring installation conflicts early and correct them before they repeat across multiple sites. That continuity strengthens cost control and improves performance over the life of a program.

In multi-site construction, consistency across mechanical, electrical, and plumbing systems is essential. Our in-house teams maintain institutional knowledge across sites, so each project benefits from lessons learned on the last. This is how we help strengthen brand standard compliance across the entire rollout.

Jupiter "JuJu"

Chief Morale Officer (CMO) Jupiter (“Juju” to his coworkers) joined the company four years ago after being adopted from Skiatook Paws & Claws Animal Rescue and has basically been running the place ever since. He comes to work every day ready to greet visitors, supervise meetings he wasn’t invited to, and remind employees to take snack breaks. While his work ethic becomes questionable after 2 PM, his office morale contributions are unmatched. When he’s not busy overseeing the office or occasionally barking during important phone calls, he can usually be found napping under his mom's desk.
