Project Description: Contractor shall provide all labor, equipment, tools, supplies, material, and incidentals necessary to place the bulkheads, rehabilitate the Conduit Service Sluice Gates, rehabilitate the gate operating cylinders including replacing the hydraulic cylinder seals, replace hydraulic piping, and replace grease lines to stem retainers. The Service Sluice Gate is the downstream of the two gates serving each Conduit. The existing system consists of a 9� X 4� concrete conduit with a partial steel liner that is controlled by a set of cast iron sluice gates, hydraulic operating cylinder, cylinder stem, stem retainer, hydraulic piping connections, hydraulic hard lines and flexible lines, control valves, and isolation valves. Work in this contract will require setting the conduit�s bulkhead. Setting the bulkhead will require lane closures, crane work, and dive operations. Work within the conduit will require entering a confined space, per EM 385-1-1. Contractor shall provide a traffic control plan and coordinate lane and road closure requests with the Arkansas Department of Transportation (ARDOT) District 9. Contractor shall be responsible for all detour signage and traffic control devices, and shall provide message boards located prior to, and in addition to, any other warning signs which notify the public of road/lane closures. Dewatering of the conduit requires placement of the bulkhead on the upstream face of the dam. The bulkhead shall be lowered into place utilizing an appropriately sized crane on the roadway over the dam. Divers shall guide the bulkhead into the cast in place guides. Dive operations in the lake will require closed spillway Tainter gates and closed conduit sluice gates 144 feet from the dive location. The dive operation must be coordinated and approved with the powerhouse superintendent, USACE water management, USACE Dive Safety, and the COR. The guides begin at elevation 660.0 which is 7 feet below the spillway crest elevation of 667.0. However, elevation 660.0 ft may be as much as 35.0 feet below the water surface. Placing and removing equipment and components into the gallery will require cranes or hoists on the bridge deck. A shaft leading from the bridge deck to the Operating Gallery is the means of entry for equipment. Mechanical Description Hydraulic Cylinders for the Service Sluice Gate in the conduits shall be rehabbed including replacement of seals. Hydraulic Piping shall also be replaced, and the grease lines to the hanger for the Service Gate shall be replaced. Disassembly of the hydraulic cylinder must be performed to gain access to the gate leaf, and all cylinder components must be reinstalled following gate leaf and cylinder rehab. Hydraulic cylinder assembly exterior shall be blasted, cleaned, and painting with the 5-E-Z vinyl coating system. Piping and Components Provide pipes and piping components in accordance with ASME B31.1 and subsequent addenda unless otherwise specified or indicated. Use seamless stainless-steel pipes in accordance with ASME B36.19M and ASTM A312/A312M, Grade TP304. �Raise,� �Lower,� and �Pressure� lines shall be Schedule 80. �Return� lines shall be Schedule 40. Pipe shall be socket welded in accordance with ASME B16.11 and made of stainless steel in accordance with ASTM A182/A182M, Grade F304. Bolted connections and flanges in accordance with ASTM A182/A182M with the grade suitable for the pipe to which attached are permitted. Any alternative pipe connections shall be submitted for approval before installation.
