The3% difference is not significant and the lift pressure usually varies from pier to pier on the job site dueto differences in structural loading.Simply use caution when using the Quick -Solve design tables.ECP Technical Design Manual -Steel Pier Design Examples2021 Earth Contact Products, L.L.C.2021-09 Chapter 7 - Page 142 All rights reserved'
