We designed a shoring job a few years ago for a client. A claim was made on our insurance. I thought that this claim had gone away as I had not heard of it. We issued plans and a sealed submittal. Months later when the contractor was doing the work they disobeyed the plans by driving the piles in to the ground without drilling the pilot shafts and when installing the beams they started to sink. They were told that they needed to plate the beams or change to sheetpile. During this time period an error on the calculations was found. The contractor installed the shoring anyways and failed to disclose monitoring data that they had that indicated that the soldier piles had sunk up to a foot in the corners and continued to sink. They also continually surcharged the excavation as both field inspections I showed up and there was an excavator and 15 foot spoil pile with the excavator on top right next to the excavation. They also drove over the beams with the excavator. During this process one of the whalers started to buckle. There was a modeling error. We told the contractor to back fill the excavation until a solution could be presented. The contractor continued reinforcing the shoring with out any sealed documents from us. Eventually the contractor cut off communication and I never heard about this again as the contractor would not respond to communication . I have our files with pictures of the site conditions as well as the excavator damaging the beams. The claims process had an engineer company do a report on the engineering error. I’m wonder what the thoughts are on this. We were never given ample time to fix the error and the contractors negligence and carelessness is a big part of why this snowballed. I’m wondering how much I should fight this. The shoring was temporary and from what I know the beams deformed but there was no sudden failure or anyone hurt.
