Lowe's Design Center

Mixed Use

Charlotte beat Dallas to become the new home for Lowe’s global technology center.  Construction on the 23-story building will include an office, parking garage, and some retail. Our scope involves slab on metal deck, the cast in place parking garage, slab on grade, and foundations on the adjacent precast garage.  

The foundations are demanding mass concrete placements due to their large dimensions. The center pile cap is 50 feet wide x 90 feet long x 7 feet thick. There are 150 auger cast, deep foundation piles, requiring our team to dig and place rebar around all of this. We successfully completed this portion of the project in 3 weeks (1,300 cubic yards, 225 yards/hour with 2 pumps).

Our next challenge is the main core, which will start below the first-floor elevation, 15 feet in the ground. The first level of core is comprised of 35-feet tall walls, including some shear, that will range from 18” to 2’ thick. We are utilizing self-consolidating concrete due to the rebar congestion.

Once we start on the garage, although our work will be typical, we will have a very aggressive schedule. Each level is 23,000 square feet and our plan is to breakdown each floor into 3 placements (7KSF-10KSF).  To meet the schedule, we will need to pour every 4th day while accommodating the city’s noise ordinance (no work before 7 am or after 9 pm) in this highly congested traffic area.

Lastly, our cast in place structure will go up to level 9. However, structural steel will begin on level 7. This will require our team to stop work for 2 weeks and then come back to install the rebar, close formwork, and pour concrete around the steel.

To ensure we are keeping up with all the details and avoiding any snags in coordination and schedule, we are enhancing our daily planning process. After our main huddle with the entire team at the trailer, our Field Leads are taking their crew to the specific work areas to plan in more detail for the day.
