Underground Construction Technology International Conference & Exhibition

This presentation will provide both a contractor's and engineer's perspective on the design and construction of a trenchless project that was completed on the Island of Nantucket. This project included the replacement of the existing wastewater infrastructure consisting of the replacement of approximately 7,200 LF of existing A.C. and V.C. gravity sewer with 8" and 10" PVC and HDPE gravity sewer and appurtenances via open-cut trench excavation (2,600 LF) and pipe bursting (4,600 LF). The contractor's challenges included transportation of equipment and manpower to and from the island via boat or ferry; conducting work without damaging historical property; working around unmarked utilities; working on brick and cobblestone roads; constant attention to residents and vehicular, pedestrian, and bicycle traffic; and coordination with weather, holidays and special island festivities.
