American Royal Building
Situation: The American Royal Center is one of the buildings located within the 14-Acre
American Royal Complex. This facility is used to host several national
conventions, trade shows, livestock shows, and industrial exhibit shows.
Cracks and wall rotation/movement were observed in several of the interior
CMU walls in addition to floor slab separation/settlement. The observed
distress and floor settlement proved to be a potential safety hazard to
the numerous fans visiting the stadium. Therefore, it was proposed that
the respective CMU walls be underpinned and stabilized to mitigate any
Solution: The Request for Proposal (RFP) was put forth by the City of Kansas and
JE Dunn. The piles were to be designed for a minimum allowable capacity
of 15 kips in compression as proposed by the project structural engineer.
Although the project was bid once before, it was determined that the winning
contractor did not have the required experience with similar commercial
helical installation. Therefore Ram Jack (KC waterproofing) who met all
the project requirements was called upon to complete the project. Once
the project was awarded, Ram Jack’s Engineering Department set upon
optimizing the helical pile diameter and helix configuration based on
the soil parameters provided in the geotechnical report. The project specification
also required a pre-production testing program which included field pile
load tests at the project site. The testing program was included to verify
the minimum embedment depth and ultimate capacity of the piles.
Conclusion: Ram Jack’s 2⅞” helical pile with a single 8” helix and
a double 8”-10” helix configuration was designed to be used
at the project site. The piles were installed quickly and efficiently
preventing any unnecessary disruptions to the facility.
