Marshalls Distribution Center The Marshall’s Distribution Center is one of the largest distribution facilities constructed in Arizona. Located on a 100-acre site with a total perimeter length stretching over 1.6 miles, one needs to see the building to truly understand. The main building is 2,008 feet long and 552 feet deep, and the footprint is approximately 1.5MSF. The building is structurally divided into two components — the low-bay (32-foot clear height) section of the building occupies 700KSF and the high-bay (52-foot clear height) area occupies 400KSF. The site had requirements beyond the 1.5MSF structure. The concrete truck court on the south side of the facility is more than 390 feet deep. The northern portion of the site is divided into two main areas — an additional truck court on the northeast side and, on the northwest side, more than 1,200 parking stalls for the facility occupants.

uniquE FEaTuRES: Beginning with the massive size, there are few structures larger than the 1.5MSF facility. Additionally, the height of the building is unique. The high-bay area is 52 feet clear to the lowest point in the canted roof. The height is twice as high as most industrial buildings in Arizona and 20 feet higher than what is considered industry norm. The 52-foot clear height presents several concrete challenges, which include 66-foot-tall concrete tilt panels and extremely strict requirements for the concrete floor. The concrete panels were cast on-site, in narrower widths, to allow a crane to erect the 150-ton panels. The concrete floors were constructed after the building was closed-in to prevent common weather elements, like sun and wind, from affecting the flatness of the concrete floors. Those floors were placed in narrow, 20-foot ribbons during a single continuous pour to eliminate perpendicular

control joints and achieve a floor flatness of F-MIN 100. This garnered the Silver Trowel award, which recognizes the flattest floors in the world.

ChallEnGES: When you juxtapose
the size of the project with the ownerrequired 11-month construction timeline, the obvious result is a considerable schedule challenge. Every element was affected by the scale of the project. When soil conditions required one foot of engineered fill, 3,750 dump truck loads of fill were trucked into the site. The project was built utilizing more than 70,000 cubic yards of concrete. This equated to roughly 7,000 concrete truckloads driven to the site and then staged so the concrete could be poured into forms, placed and finished. To overcome these challenges, the project was broken down into manageable sections so trade contractors could work in separate areas and create project flow.
