Trenching. Trenching will occur from the rear lot line to the premises.
Trenching. If this AGREEMENT involves digging trenches or other excavations that extend deeper than four (4) feet below the surface, CONTRACTOR shall promptly, and before the following conditions are disturbed, notify the DISTRICT in writing, of any:
Trenching. All trenching from the pole or pedestal to the meter base of the user of electricity will be done by journeymen linemen who may be assisted by apprentices.
Trenching. All trenching from the pole or pedestal to the meter base of the user of electricity will be done by journeyman linemen who may be assisted by apprentices. An individual homeowner may dig his own trench in order to preserve trees and shrubbing or for other aesthetic reasons.
Trenching. Unless otherwise specified, the following pay items INCLUDE:
Trenching. All trenching from the pole or pedestal to the meter base of the user of electricity will be done by journeymen linemen who may be assisted by apprentices. This shall not preclude an individual homeowner or owner of a duplex or four-plex from digging his own trench. Employer will ensure nothing is performed by the homeowner beyond the mere digging of trenches. Parties agree that commercial builders in the construction industry building for speculation shall have trenches for housing projects dug by I.B.E.W. personnel.
Trenching. Some nbn™ connections require a lead-in cable between the network entry point (outside the Home) and the first socket or main distribution frame (MDF) if residing in an apartment. The lead-in cable connects your Home to the network to facilitate the connection of a working Service. Some premises may not have a lead-in cable, and will require installation - either aerially or underground. If the lead-in cable is to be installed underground, this may require trenching. We will recommend to you a suitable provider to do this work, if this is the case. More information about trenching is available on the Foxtel Website.
Trenching. Trenching depth shall be such that there shall be a minimum of 400mm cover over all installed pipelines. A redundant water pipe running between the upper and lower fields is to be used as a conduit for the mainline pipe and cable. If this is found to not be suitable trenching and backfilling of this section has been included as a provisional item. Purpose-built continuous chain or rotating ‘wizzwheel-type’ trenchers with the capacity to elevate spoil via a conveyor belt system onto an adjacent vehicle shall be the preferred machines for trenching. Spoil shall not be allowed to fall adjacent to the trench or be deliberately placed on the surface prior to removal. Trenching near trees and crossing of pathways may be required to connection to the exiting water supply. As such, the Contractor is to visit the site to familiarise themselves with the requirements. Backfilling Backfill shall be carefully placed over the pipe initially as a 200 mm depth layer. The soil shall be consolidated by foot tamping over the pipe. The balance of the trench shall then be backfilled. The trench shall be finished flush with the surrounding ground level and consolidated so that no subsequent settling occurs. The final 150 mm of backfill shall be of approved topsoil quality. If it has not been possible to separate excavated topsoil for this purpose, imported and approved topsoil shall be used. Backfilling around the pipe shall not cause displacement, deformation or excessive stress to the buried pipe or fittings. All excavated spoil surplus to backfill requirements shall be disposed of at the Contractor’s expense. Drainage system repairs Any drainage laterals or other underground services damaged by trenching for the irrigation system shall be repaired before backfilling occurs. Repair of drainage lateral pipes shall be made by way of a suitable repair coupling or other method approved by the field drainage contractor.

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.
Trenching. Abandoned pipes and conduits encountered during trench excavation shall be removed the full width of the trench. If a pipe is encountered by multiple trenches, remove pipe the full width of affected area.
