Founded in 1923, we build and connect the world’s strongest utility infrastructure networks. As a premier, privately held construction and engineering contractor, we serve leading companies in the power, oil & gas pipeline, gas distribution and communications markets.
Our generations of workers pride themselves on connecting with customers and helping them connect with the world.
Over time, we have grown from a tree-trimming and landscaping company into a nationwide utility infrastructure contracting firm with more than 70 offices. We operate under two wholly owned subsidiaries: Henkels & McCoy Inc. and HMI Services.
Using our proven Connected Infrastructure Model™, we connect all fundamental parts and processes of successful infrastructure construction. Over the past century, we have successfully designed and constructed millions of miles of safe, reliable and world-class infrastructure for our utility, commercial and government customers.
We consistently rank in the top 10 of Engineering News Record’s ranking of Specialty Contractors.
Connections for Generations™
