This project studied the effect of leaving excavations open longer than 24 hours. It was considered that excavations left open and unsupported might lead to subsidence and consequent damage to the road surface around the excavation. Water utilities were contacted regarding their policy on reinstatement, and a literature search conducted. It was found that water utilities are moving away from the practice of delayed reinstatement, so that it should not be a cause for concern in future.
