One can speculate that a geotechnical engineering study of 2D slope stability conditions could have predicted this failure based on the slope geometry and soil type. construction, foundation failures, extraordinary loads and corruption. Construction is perhaps the most critical stage in the life cycle of structures, mainly because of the danger of failure and the high chances of underestimating construction loads.
