The St. George LDS Temple Chiller Addition project started on February 5, 2013 and was completed August 24, 2013. The project consisted of demolishing the existing trash enclosure and cooling tower shelter, and the subsequent construction of a new 4,460 SF concrete mechanical room and cooling tower enclosure.
The new mechanical equipment is housed in a concrete structure completely below grade and the cooling towers on a slab, semi-recessed below grade. Painted architectural concrete and acrylic stucco were used to match the original finishes on the temple. Construction was challenging, with the excavation in some areas exceeding 30 ft in depth, and requiring large hammers to penetrate the bedrock. The new construction involved intimate structural coordination with the existing temple annex and facility that remained in service during the project. The design and construction team focused on clear communication and precise coordination, which ensured that the project met key delivery dates and cost parameters. The new equipment will serve the St. George LDS Temple with a state-of-the-art, energy efficient, HVAC systems.
