Industry Case Study: Hotel Indigo Addition
Challenge
Situation: The plans called for caissons to carry the column loads for a new balcony addition. The steel cages had been delivered to the job site but when the drill rig arrived it was determined that the space was too tight to be able to utilize the large equipment.
Challenges: Smaller equipment needs to be used because of the tight areas around the pool and next to the building. Designing a support system that would carry the required loads. This change in plans was causing a delay that was going to make it difficult to meet the scheduled completion date.
Solution
Solution: It was determined that the installation of pre-construction helical piers was the best option. The equipment needed was small enough to fit into the tight spaces. The Arizona Foundation Solutions engineers were able to work with the structural engineers to design a pier system to carry the required point loads for the steel support columns.
Conclusion: A total of 13 helical piers were installed with pre-construction caps. The rebar was attached to these caps and the concrete pier caps were poured. This system was installed in 3 days and not only solved their problem but was able to put the project back on schedule.
