Advanced Geosolutions Inc. (AGI) performed Rapid
Impact Compaction (RIC) to improve the ground
conditions at the Downtown Stadium project in
Spokane, Washington. Using data acquired, AGI
created a deflection map allowing Budinger &
Associates to easily determine the sensitive areas
with high deflection. Once determined, Budinger &
Associates performed post-improvement Standard
Penetration Tests (SPT) to verify that the soil
improvement achieved a minimum value of 18 blows
per foot at each tested location. AGI successfully
improved the fill soils and achieved the minimum SPT
values required. This was the first application of RIC
ever performed
