The court found that the contractor and the site engineer were guilty of negligence as the contractor didn't follow the building code requirement and the site engineer didn't inspect the work properly. Inadequate test data can cause serious delays, cost overruns, damage, and even collapses. The piles broke because of the consolidation of the organic clay. It proved to be a total success as practically all movements within the adjacent structure stopped. Additionally, the building was originally designed in two halves, with one side only two stories and the other side three stories.
