Since its start as a small utility business in 1980, LEO Construction Company has remained rooted in northern Virginia, even as its services diversified and it entered its second generation of family leadership. President and CEO Michael Rose continues to strengthen the legacy left by his father and uncles, who helped reorganize and rebuild the business in its early years. Their experience and persistence shaped the foundation that still defines LEO Construction.
“My father, Tom, started in overhead transmission and right of way work, then had the opportunity to become an owner at LEO Construction,” Rose said. “He brought in his brothers, took over as President, and got the company back on its feet. I followed him into the business and learned everything I could from him.”
Today, LEO Construction focuses on underground power and communications work across Prince William, Loudoun, Stafford, and Fauquier counties. It operates out of two locations, Leesburg and Bristow, Virginia, and has a corporate office in Aldie, Virginia. LEO Construction’s territory includes both public and private projects, from utility infrastructure to commercial and residential development. Its crews are experienced in all types of underground electrical construction, including fault repair, duct banks, manhole setting, and energized splicing.
“Our work is primarily dry utilities,” Rose said. “We handle everything from erosion control and clearing to full installation and restoration. We have long-term contracts with Dominion Energy and Northern Virginia Electric Cooperative. We probably have about 40 percent of our people working in that field, and 60 percent of our staff works for general contractors in the data center side putting in the power, communications, security, streetlights, and infrastructure. We also work for developers and builders, putting in their main line electrical needs in their subdivisions, and we can work on commercial buildings as well, putting the power in.”
LEO Construction employs about 110 people, a figure that has remained consistent for more than two decades. Rose attributes that stability to a focus on culture and mutual respect.
“More than half of our workforce has been here for over 20 years,” Rose said. “It’s one of the things that I think my father and his two brothers instilled, which is keeping that family feel with the company and their employees, seeking out and getting good people to work for us, and treating them well. It’s important to us that our employees want to stay and grow here.”
To ensure its staff can complete its range of projects efficiently, LEO Construction has an equipment fleet that includes nearly 30 Komatsu machines, from various excavators to large dozers and wheel loaders. Crews might dig a secondary line with a Komatsu PC35MR Mini Excavator or set 35,000-pound concrete vaults with a large Komatsu PC490LC Excavator.
“The PC490 is a difference maker because we can remove the counterweight and keep transport weight under 80,000 pounds while still lifting heavy structures,” Rose said. “We avoid bringing in cranes, which saves time and cost. The PC35 is on the opposite end of the spectrum and gives us the versatility to work in tighter spaces where the power isn’t needed, but reliability is still expected.”
For trench work, midsize excavators are the company’s workhorses. The Komatsu PC138USLC and PC238USLC Tight Tail Swing Excavators serve as everyday problem-solvers that swap attachments quickly.

“Our PC138 units are our Swiss Army knives because they move from auger to hammer to tamper in minutes with quick couplers and monitor presets,” Fleet Manager Frank Thyson said. “Even newer operators can make those changes fast and keep production moving.”
When a project hits rock, LEO Construction relies on an NPK GH15 Hydraulic Hammer.
“The NPK hammer is reliable, and we can move it from the 360 down to the 138s,” Rose said.
LEO Construction utilizes intelligent machine control (IMC) equipment, like the Komatsu PC490LCi Excavator, to keep operators on grade as a project progresses. Komatsu’s Smart Construction 3D Machine Guidance, an aftermarket solution, is installed on the tight tail swing excavators.
“GPS has changed the way we operate because it reduces rework and provides documentation that backs up our layout and our as-builts,” Rose said. “It is a safety net that protects schedule quality and helps us control our costs.”
Data from the Komatsu equipment is accessed and interpreted either on a browser or within the My Komatsu and Komtrax telematics apps. Thyson and his team track codes, fuel consumption, and idle time to get ahead of issues and keep machines productive.
“I check Komtrax every day because it shows exactly what we need to see, and it lets us troubleshoot before we call for service,” Thyson said. “That keeps us efficient and reduces downtime. My Komatsu puts the parts book, the trouble code tree, and ordering in one place, which simplifies everything for our team. It also keeps our service intervals current and makes planning services easier.”
For its equipment needs, LEO Construction works directly with John Rocca, a Sales Representative for Linder Industrial Machinery Company, who has supported the Rose family for more than three decades through several ownership transitions and market changes.

“John stands behind every deal and gets the right people involved immediately when something needs attention,” Rose said. “He’s been an irreplaceable asset. We stay loyal to Komatsu because of him and his efforts, Linder’s leadership team, and because we just haven’t had any downtime.”
That trust comes from consistency and accessibility. Rocca remains the company’s first call for questions about parts, service, technology integration, and machine specifications.
“John understands how we work and what we expect from our fleet,” Thyson said. “When we need help, he connects us with the right people fast.”
With expanded inventory, parts availability, and product support staff, Linder continues to strengthen its footprint in an area where utility and data center projects demand reliability.

“Response time and follow-through have improved noticeably since Linder became the Virginia dealer, and that gives us confidence when we’re taking on new work,” Thyson said.
Moving forward, LEO Construction’s market remains strong with steady utility work and continued demand for data center infrastructure. According to Rose, that growth will stay measured and aligned with the company’s family culture of promoting from within.
“We see opportunity for the next several years as the grid catches up and as communication networks keep expanding,” Rose said. “We will keep our safety-first mindset to deliver quality and production on every job. As we continue to take on new projects, we want people who bring an honest day’s effort, and we’ll give them a path to grow from laborer to operator to supervisor. We remain an equal opportunity company, and we invest in the people who invest in us.”
