👉 Hold engineering, also known as hold-up or support engineering, is a specialized field within civil and structural engineering that focuses on the design and construction of temporary supports and structures to stabilize and protect soil, slopes, or other surfaces during the construction process. It involves creating temporary frameworks, such as retaining walls, mats, and anchors, to hold back earth or prevent erosion while excavation or construction activities are underway. This engineering approach is crucial for ensuring site safety, maintaining structural integrity, and facilitating smooth project progress by mitigating risks associated with unstable ground conditions.
