Davis-Houk Mechanical, a union mechanical contracting firm rooted in Coles County, Illinois, has landed the full design-build mechanical contract for retailer Rural King's new three-building Store Support Center in Mattoon, now under construction and slated for completion by 2028. For a firm operating in what the industry typically calls a tertiary market, the win is a clear demonstration that scale and big-city presence are not prerequisites for major commercial project capability.
The market thesis behind the win: Chris Rennels, a Coles County native who returned home after earning a mechanical engineering degree at the University of Illinois at Urbana-Champaign, built Davis-Houk's satellite branch around a specific bet — that the Charleston-Mattoon area, recently ranked the number one micropolitan area in Illinois and 25th nationally by Site Selection Magazine, was positioned for sustained growth that larger contractors based in Chicago or other metro markets were overlooking. Coles Together CEO Ronda Sauget pointed to substantial growth throughout the region as validation of that bet.
The in-house fabrication strategy: What separates Davis-Houk's approach from a typical regional contractor is full in-house fabrication capability for sheet metal, piping, and plumbing out of its Urbana fab shop, coordinated through BIM and Revit models down to prefabricated hangers. Rennels was direct about why this matters on a fast-moving job: it is not just about cost, it is about schedule, ensuring that on parallel construction tracks across three buildings, no trade is left guessing what another has already installed.
The technical specification worth noting: The mechanical systems being installed across the Store Support Center campus use variable air volume with hot water reheat, full direct digital controls, load balancing, and demand-control ventilation. Rennels specifically highlighted the demand-control ventilation strategy — conditioning outside air only when actually needed — as significant for both utility incentive programs and long-term operating costs, particularly given that the campus includes an event center where occupancy can swing from a few dozen to more than a thousand people, requiring controls flexibility that a simpler fixed-ventilation design could not deliver.
What this means for contractors evaluating their own market positioning: The Davis-Houk story is a useful data point for mechanical and HVAC contractors operating outside major metro areas who may assume that large design-build commercial work is only available to bigger regional or national firms. A combination of deep local relationships, in-house fabrication capability that improves schedule reliability, and genuine technical competency in modern controls and ventilation strategy positioned a contractor based in a town of roughly 18,000 people to win a multi-year, multi-building commercial contract against what was presumably broader competition.
The growth context: Rural King's decision to build a major Store Support Center in a tertiary Illinois market, rather than a larger logistics hub, reflects a broader pattern of retail and industrial investment moving into smaller, lower-cost communities — a trend that creates commercial HVAC and mechanical opportunity in markets that have historically seen less of this type of large-scale project work.
