Carter Hotel Demolition
- LocationDuluth, Minnesota
- TimelineMarch - April 2019
Michels, one of the Nation's largest deep foundations contractors, installed 12 soldier piles for a permanent precast concrete retaining wall. Each soldier pile consisted of a 24-inch wide flange beam weighing 279 lbs per foot and was installed in 42-inch diameter and 13.5 feet deep rocket sockets in basalt bedrock.
Though Michels crews completed the installation in spring, the team still faced harsh working conditions: the temperatures ranged drastically from -18 to 45 degrees. The project was completed adjacent to the remaining building foundations and in close proximity to the neighboring building, resulting in a restrictive work site.
Additionally, the work site was divided into two work platforms with a grade difference of approximately 5 feet. Aggregate base was used to provide safe, stable work platforms and access ramps.
