This 515,000-sq-ft, Class A high-rise combines 23 floors of leasable office space with two floors of ecclesiastical space for the Church of Jesus Christ of Latter-day Saints. The project team used a monolithic concrete pour for the core mat foundation, using about 3,300 cu yd of concrete.
The large amount of concrete required the routing of cooling pipes through the foundation even though the concrete was poured in below freezing temperatures. The team monitored temperatures in multiple locations throughout the foundation to ensure even distribution of heat and prevent delayed thermal cracking or the formation of ettringite on the concrete.
