Kent Companies Southeast Project Profile
Corning Headquarters Core and Shell
Submitted by Steve Clark, Project Manager
General Contractor: Balfour Beatty Construction
Location: Charlotte, North Carolina
Corning Optical will soon have a new home. The Charlotte team is Making it Happen.
Corning Optical builds advanced glass components such as optical fiber for fiber optic communication networks. Corning’s new headquarters is a five-story, 182,170 square foot building situated in Charlotte’s Riverbend Village development. Balfour Beatty Construction turned to our team for the building core and shell.
Corning Headquarters by the Numbers:
- 1,600 cubic yards of foundations
- 34,400 square feet of slab on grade
- 180,100 total square feet of slab and deck (The roof is slab on metal deck for roof and the lower level walk-out basement is part slab on grade and part slab on metal deck.)
- 5,860 square feet TCA basement retaining wall
- 2,125 square feet TCA one-side basement retaining wall against soil nail wall
- 5,860 square feet TCA site retaining wall with board plant form liner
- 141 tons of rebar
- Over 5,400 cubic yards of concrete
- CIP walls and columns
What’s interesting about this project?
This project used a soil nail wall and CIP one-sided wall to save an old growth oak tree immediately adjacent to the basement excavation (the tree can be seen in the image gallery below). Careful planning went into the interaction between the two different walls. The soil nail wall design originally sloped along one side as the grade dropped. Kent field and office management met with Morrison Engineers (soil nail wall contractor) before the project started to develop a method to step the top of the soil nail wall in to erect formwork for the concrete scope. This led to a basement wall that is partially one-sided and two-sided in a single pour.
Upon completion, Corning Optical will accommodate up to 650 employees at the new location. Click here to read the official story from the Charlotte Observer.

“Working with Kent Companies on this monumental project has truly been a pleasure. Jonas Flores, site superintendent, has exceptional attention to detail, communication, and positive attitude. Jonas goes above and beyond to maintain schedule as we’ve experienced a wet winter, but we have been able to stay on track. We look forward to a successful finish to the Corning HQ and future work with the Kent Companies team.”
