Trenching. Daily trenching operations will consist of trench excavation, dewatering (where necessary), conduit installation, and backfilling activities. Excavations will be conducted so as to not disturb adjacent buildings, streets and utility lines. Trenching near existing structures and utilities (i.e., crossings of existing services) will be done by non-destructive means (e.g., by hand, vacuum) as necessary. Trenching near existing structures (e.g., manholes, lampposts, signposts, etc.) will provide a minimum of 12 inches between the structure’s surfaces and the sides of the trench excavation. Fences, markers, culverts, underground structures, utilities, and other appurtenances will be protected accordingly. Open trenching will typically consist of pavement saw cutting followed by digging using a rubber- tired or tracked backhoe or excavator. Trench excavation will follow NYSDOT Standard Specifications §206 – Trench, Culvert and Structure Excavation as appropriate. Trenches will be excavated to the lines and grades necessary for proper conduit clearance, bedding and stabilization. The minimum trench width must accommodate a clear working space of six inches around the maximum outer diameter of the conduit arrangement and be of sufficient width to permit proper joining of conduit and backfilling. Trenching work will be confined within the limits of the permitted disturbance. There are no identified wetland areas, vegetated freshwater or tidal wetlands within the upland construction area. As a result, no trenching or construction activities will occur within wetland areas. Any tree root encountered in the trench will be cut back far enough so that the root will not interfere with the conduit. In addition, stumps, roots or other material will be removed from the trench. Trench side slopes will be protected appropriately as required (e.g., sloping, shoring, and shielding) as per the NYSDOT Standard Specifications. Trench excavations will be maintained until backfilled adequately so as to provide workers with a safe working condition and protect the work, existing property, utilities, and roadway. Controls will be in place to prevent unauthorized access to pedestrians and surrounding public.
