Common use of Major Repair Clause in Contracts

Major Repair. Major repair of tidegates and floodgates that discharge to natural watercourses are covered under this agreement. Major repair actions include all maintenance activities, not categorized as minor repair, required to keep the tidegates and floodgates operational. These actions include, but are not limited to: the replacement of doors and collars; replacement and installation of liners; repair of discharge pipes and tubes; repair of rock armoring or thresholds; and, in rare instances, debris removal requiring the access of heavy equipment within the watercourse. Major repairs shall not include actions that require excavation of the dike or levee to accomplish the repair. Replacement of doors may require the use of heavy equipment, such as a boom truck or excavator, depending on the type of door, size and material. Any heavy equipment used is staged and operated from the dike or bridge. The door is suspended over the dike, near the tube opening, and is manually connected to the collar. Work is conducted during a low tide cycle and no cofferdam is required. Replacement of collars is rarely necessary, but in instances when a collar requires replacement, the work is performed manually during a low tide cycle and no cofferdam is required. Lining of a tube consists of installing a liner to the inside section of the tube where corrosion typically occurs. To line an existing tube with new material, the work must be conducted during a low tide cycle when the tube can be easily accessed. Any debris in the existing tube is removed so that the liner will fit properly. The new lining material is installed within the existing tube by utilizing a boom truck or other equipment that can lift and suspend the new liner over the watercourse near that tube opening. The equipment is staged from the dike (or bridge) and does not enter below the OHW or MHW elevation. Once the liner is in position it is manually placed in alignment with the tube and then secured to the existing tube. The new liner is grouted into place to provide a seal between the tube and the liner. Discharge pipe or tube repair consists of patching holes or cracks in the protruding ends on either side of the dike. The damaged area is patched with cement or fiberglass, depending on the composition of the pipe or tube. Patches are typically used to repair small holes or cracks. If the damaged area is large enough that a patch will not work the protruding end of the pipe will be encased in cement. These are typically temporary repairs to prolong the life of the pipe or tube until it can be replaced. These repairs are completed manually during a low tide cycle and no cofferdam is required. If equipment is needed, such as a cement truck, it will be staged and operated from the supporting/associated dike or bridge. Repair of rock armoring or thresholds is required when existing rock has shifted, or a storm event has caused erosion at the structure. Repair work typically involves the repositioning of existing rock that has shifted. In some circumstances, new rock may need to be imported to the repair site, typically 10 cubic yards or less, to restore the original footprint of the rock armoring. Equipment is staged from the associated dike or bridge. The need to operate equipment within the watercourse for debris removal is very rare. Typically, all debris can be removed either manually or with equipment staged on the bank. Operation of equipment within the watercourse for the removal of debris shall only occur to prevent the loss of a tidegate or floodgate structure, including the dike or bridge supporting that structure. This action will be completed during one low tide cycle. If the equipment enters the channel then the site where the equipment enters the channel will be isolated from the rest of the channel and salmon removal implemented. If water is flowing in the channel, then the flow will need to be bypassed around the isolated area.

Major Repair. Major repair of tidegates and floodgates that discharge to natural watercourses are covered under this agreement.
