Conco concrete crews recently placed and finished 60,000 square feet of slab on grade for the Vornado Warehouse Expansion in a single pour. Getting 1,100 cubic yards of concrete on the ground in 7 hours requires great vendors, seamless planning and fantastic team work. The pour started at midnight on Thursday and finishing crews worked through most of Friday. Structural steel will be starting next week and we have another 45,000 square foot pour coming up soon.
