GR Concrete Construction provided turnkey cast-in-place structural concrete services for the Cherry Creek Waste Transfer Station Expansion in Denver, Colorado. Working under FCI Constructors for the City and County of Denver, the project required the execution of large-scale structural foundations, heavily reinforced vertical wall systems, high-load structural flatwork, and exterior site concrete to support expanded municipal waste transfer operations.
The scope included more than 1,200 cubic yards of cast-in-place concrete foundations reinforced with over 65 tons of reinforcing steel. Foundation systems consisted of 24-inch to 36-inch spread footings supporting vertical cast-in-place concrete walls ranging from 20 to over 38 feet in height. These wall systems incorporated integrated tie beams, pilasters, and suspended beams, requiring dense rebar placement, complex formwork assemblies, and carefully sequenced concrete placements.
Structural flatwork operations included approximately 500 cubic yards of concrete reinforced with 40 tons of steel. Work encompassed a tipping floor constructed with 10-inch and 14-inch slab-on-grade sections, as well as elevated structural decks measuring 12, 14, and 18 inches thick. All slabs were reinforced with double-mat reinforcing steel ranging from #5 through #8 bar to accommodate heavy operational loading and long-term durability requirements.
In addition to the building structure, GR Concrete Construction installed approximately 700 cubic yards of exterior heavy-duty concrete paving with reinforced and doweled control joints designed for continuous truck traffic and municipal equipment loads. The expansion mirrored the existing facility and doubled the operational capacity of the Cherry Creek Waste Transfer Station for the City and County of Denver.
