Topic Description:
This case study will discuss the renovation to the Historic Provo City Temple in Provo, Utah that suffered significant damage from a fire in December of 2010. As part of the rebuild, the Church of Latter-Day Saints wanted to add a two-story underground addition underneath the existing at-grade structure. Nicholson was contracted to provide a design/build solution which allowed the existing remaining brick façade to be underpinned in-place allowing the General Contractor to construct the substructure 35-feet beneath the façade.
The novel design approach employed by Nicholson provided a micropile underpinning system that supported the Temple façade 35 ft in the air allowing the substructure to be built. In addition, a large trenching machine was employed to construct a 50 ft deep cutoff wall around the perimeter of the work zone in order to limit the potential impact of the dewatering efforts.
This case study will present the engineering and construction efforts that went behind the reconstruction of this significant temple for the Church of Latter-Day Saints.
