Air Separation Unit Facility Expansion
Kelley Construction delivereda high-impact, multi-scope civil construction package for the expansion of anAir Separation Unit (ASU) facility in the Clarksville, TN area, supportingincreased industrial gas capacity to meet rising regional demand.
Over the course of nearly ayear, Kelley successfully executed critical site development and structuralfoundation work in a challenging active plant environment. Crews worked throughextreme seasonal conditions ranging from summer heat to winter snow, all whileoperating within a tight jobsite footprint shared by multiple trades andongoing facility activity.
Kelley self-performed andmanaged a substantial scope of work that included placement of 10,000 tons ofstone, nearly 12,000 cubic yards of soil excavation, installation of 420 tonsof rebar, and placement of 3,500 cubic yards of concrete. The project featureda diverse range of complex structural foundations, including Cold Boxes,various Compressors, Skid and Pipe Racks, and Cooling Water Tower Foundations.In addition to the structural scope, Kelley delivered critical siteinfrastructure improvements such as stormwater piping and catch basins, ductbanks, grounding systems, gas and water line relocations, roads, truck loadingscales, laydown areas, bollards, and fencing.
Execution required a highlevel of technical expertise, particularly in managing complex foundationgeometries and monolithic compressor foundation pours within a live,space-constrained facility. Kelley also operated within a client-ledjust-in-time design framework, coordinating closely with the design team tokeep construction moving efficiently by aligning field execution with phaseddocument release. This approach allowed the project to start quickly whilelater design packages continued to develop.
Through disciplinedQA/QC, strong safety leadership, and proactive subcontractor coordination,Kelley delivered seamless execution across every scope. The result was asuccessful, on-schedule project completed without compromising quality, safety,or performance.
