Haydon is an employee-owned general contractor based in Tempe, Ariz. Gary Haydon started it in 1991 as the building arm of mechanical subcontractor SDB Inc., and it later became Haydon Building Corp. A heavy civil division followed in 1998, and that’s what gave the company both vertical and horizontal work. It’s grown since into a group with its own landscaping, underground electrical and utility rehab outfits. Katie Haydon now runs it as CEO and chair. This week Haydon showed up as Bedrock Robotics’ newest named customer. It’s running autonomous excavators for earthwork on a remote Texas site and plans trenching tests next. Data centers and water plants are where it wants the machines working.
Six self-performed trades is the number that explains this contractor. Earthwork, concrete, utilities, landscape, electrical and virtual design are all carried in-house, which is unusual breadth and is the practical reason one company can bid both a building and a highway package.
The site and utilities scope is granular enough to be worth reading in full: yard piping, water and sewer systems, storm systems, dry utilities, lift stations, mass grading and excavation, site preparation, flood control, clear and grub, fine grading, field survey and layout, and SWPPP installation and maintenance. Concrete work covers structural vertical concrete, structural retaining walls, site concrete and flatwork, specialty and decorative finishes, bridge construction, pour-in-place box culverts and Portland cement concrete paving, plus diversion and dissipation structures.
Four subsidiaries extend that further. Origin D and T handles building information modelling. Omni Electric covers electrical and communication infrastructure. Earthscapes does civil and community landscaping. Desert Infrastructure Services handles manhole work. A manhole-services company is not something a general contractor acquires by accident; it points at sustained municipal utility rehabilitation work.
Markets are named across ten categories: advanced manufacturing and industrial, data centres and mission critical, site development, transportation, water and wastewater, healthcare, civic and government, higher education, commercial and retail, and parks and recreation.
Equipment is where a heavy civil contractor’s capability actually lives, and Haydon reports a fleet of more than 500 pieces. On a remote site, owning plant rather than renting it is usually the difference between holding a schedule and waiting on a mobilisation.
Ownership is stated as 100% employee owned, and the company publishes Arizona ROC licences 330740 and 330372. It describes its origin as a small family-owned business that grew into one of the largest local construction companies in the Southwest, with a 1991 marker on its timeline and more than thirty years cited.
One small detail from the recent work that says something about the shop: it restored a historic Litchfield train station chandelier for a new library. That is not a line item any heavy civil contractor advertises for marketing reasons.
The site names no safety award or trade association despite maintaining a safety page, and publishes no headcount, so prequalification figures should be requested directly.
