Scope Of Work
Corning Distribution Center is a built-to-suit Design-Build regional facility in Tarboro, NC. The project includes 750,000 SF of warehouse space with a 30,000-SF office upfit.
With multiple loading conditions, deeply evaluating the subgrade reactions for Corning’s distribution center was critical in ensuring long-term performance of the slab. Originally designed as a 7-inch-thick slab based on preliminary reviews, upon more in-depth study with the geotechnical and structural engineer, Choate determined the floor slab thickness really needed to be a reinforced 9-inch-thick slab.
A solid understanding of the soil types was critical to that game-changing review. The soil in Rocky Mount appears to have good bearing (3,000psf) and good blow counts (15-20). But look a little deeper, past the upper 15 feet of soil, and you’ll find blow counts decreased dramatically (to 2-4). Combining that intel with Corning’s future loading conditions, the real (k) value became apparent.
Without the extra two inches, bringing the slab thickness to 9 inches, stress cracks were imminent.
Getting the correct (k) value was critical in leading the team to the correct design for the floor.
