Rigged a 90 tonner on a dock, came back next day and the whole pad had settled 6 inches
Set up on a timber pier in Galveston last Tuesday, leveled the outriggers perfect on 2 layers of 4x8 mats. We came back Wednesday morning to knock out the rest of the job and the pier deck was sitting 6 inches lower on the rear starboard side. Turns out the old piling underneath had been rotting for years and the load settled it into the mud overnight. We spent 4 hours re-spreading mats and re-leveling before we could lift a single beam. Has anyone else had a ground pad shift that much after setup, or was I just lucky enough to get the worst piling in the harbor?
Did you check the other pilings under that pad or just the one that sank? Curious if the whole row was soft or if you got unlucky with a single bad one.
