The existing site was the last phase of a six building project that stalled at completion of foundations. Salt Lake 6 LLC, a local developer focused on affordable workforce housing, worked with the original developer to complete a project on this site. The final project configuration included a 17-story residential tower and a five-story stand-alone parking structure. The total residential floor area consists of approximately 241,000 sq. ft. with repetitive foot floor plates on the 2nd through 17th floors. The first floor has a similar floor plate and houses mechanical and electrical rooms. The 87,000 sq. ft. parking structure accommodates 534 vehicles.

Client Benefits

Detailed early planning allowed the team to utilize existing foundations and re-introduce efficient forming systems to create a cost-effective building system that could be priced affordably. The project was completed in the months following the financial meltdown of 2008. While the rest of residential development throughout the U.S. was in turmoil, only a few buyers did not close on their units. Ultimately the project was 100% sold.

The Science and Design of Structural Engineering

While most would consider working on a site with existing foundations in place a challenge, this team saw it as an opportunity to incorporate the existing foundations into the new design to reduce costs. The team also looked at incorporating low-cost tunnel form construction into the project. Since the technology had not been used in the islands for many years the team, including key subcontractors, traveled to construction sites across the U.S. to better understand the techniques’ impact on the various subcontractors.
