This large scale, long-term project is designed to reduce combined sewer overflows (CSO) and includes challenging near-surface work in congested urban environments, where successful execution will require careful planning around existing utilities, limited work areas, public access, traffic control, and coordination with multiple project stakeholders. On the ALCOSAN Ohio River Tunnel Project, this includes managing near-surface scopes such as shafts, support of excavation, utility relocations and protections, access improvements, site logistics, and surface-level civil work in dense urban settings.
