Building 3 had been experiencing substantial leak and moisture infiltration problems for many years. The building, constructed in 1958, featured a Flemish header bond that differs greatly from the methods used in today’s masonry practices.
Heartland recieved the award for the project in 2010. Shortly after award, exploratory demolition began and revealed a myriad of problems with the existing CMU backup wall. As a result, the project required significant redesign in order to facilitate the facade replacement. HCI teamed with a local engineering firm to design a retrofit relief angle system that could attach to the existing steel frame while not compromising the 50-year-old structure.
In addition to the complex relief angle design, HCI also had to develop a wind-bracing system that would protect both the new masonry and exposed backup wall conditions from wind exposure. Without this system, the existing backup walls would be susceptible to structural failures and collapses.
This $49 million project was completed in August of 2015.
