Ice Harbor Navigation Lock Downstream Gate Hoist Machinery Upgrades

The work described herein involves the replacement/upgrade of the navigation lock downstream gate hoist mechanical machinery and the associated electrical and control equipment, and the rehabilitation of the gate hoist friction sheaves. Background The Ice Harbor navigation lock downstream gate is a counterbalanced vertical lift gate and measures approximately 90 feet tall by 88 feet wide and weighs approximately 740 tons. The gate is connected to two counterweights (one on each side) with twelve 2-1/4 inch diameter wire ropes. The hoist machinery is located in two machinery rooms located at the top of the downstream structural towers, one on each side of the lift gate. The wire ropes pass over an 18 foot diameter friction sheave. The friction sheave is driven through an electric hydraulic pump driving a high speed hydraulic motor. The speed is reduced and torque increased through a gearbox having an external pinion driving the gear around the perimeter of the sheave. The wire rope passes over the uppermost surface of the hoist sheave. The two hoist sheaves support the cumulative weight of the gate, the counterweight, and the hoist ropes. The downstream lift gate hoist machinery is the original machinery installed when the lock was placed into service in 1969, with the exception of a coupling (replaced in 1980), pedestal mounting system (added in 1980), output gear in box (reversed due to bent shaft in 1980), gearboxes and hydraulic system (replaced in 1989), hoist wire ropes (replaced in 2012). Electrical and control systems are original. Summary of Work Mechanical upgrades consist of the hoist drive components required to operate the gate, the overhead service crane in each machinery room, and the mechanical aspects of limits and controls for gate operation. Furnish and install the following items for the hoist drives in each machinery room: new pillow block bearings, ring gears, pinion gears, pinion shafts, pinion bearings, couplings, and brakes. In addition, install new Government furnished gearboxes. Install new bearings and ring gear for the friction sheaves in each machinery room. In order to replace the friction sheave bearings and ring gears, the contractor must have technical experience, labor, and physical plant required for jacking and shoring of the existing 18 foot diameter friction sheaves that weigh approximately 112,000 pounds each and the counterweights which weigh approximately 740,000 pounds each. Upon completion of the bearing replacement, the contractor will be responsible for precise alignment of the friction sheave bearings and the alignment of open gear contact between the new pinion gears and the existing friction sheave ring gears. Miscellaneous elements of the contract include RCRA 8 metal based paint and asbestos containing material (ACM) removal and disposal from existing equipment, and reroofing both tower roofs with a liquid applied membrane. The contractor will be responsible for gate hoist wire rope load balancing that will require the services of a qualified engineer with a minimum of three years experience with load cells and load monitoring equipment to ensure the loads are evenly distributed across all hoist wire ropes at the completion of the work. The overhead service cranes in each machinery room will be replaced with commercially-available four ton rated electric wire rope hoists. New overhead cranes shall be single-girder top running bridge-type furnished with pendant style pushbutton remote control and wall-mounted pushbutton control station. Structural upgrades consist of weld repair of the downstream gate hoist friction sheaves, fabrication and installation of new machinery supports and pedestals, fabrication and installation of new safety handrails, and structural modifications to the existing overhead service crane corbels. Structural modifications to the existing overhead service crane corbels consist of the installation of an adhesive anchor system to increase the load capacity of the corbels from 5,000 pounds to 8,000 pounds. Evaluate concrete drilling locations for the presence of existing reinforcing steel with Ground Penetrating Radar or an approved equivalent method. Electrical upgrades consist of replacement of the machinery room motor control centers and power supply wiring and circuit breakers, installation of new variable frequency drive (VFD) equipped motors, new main power disconnects, new power distribution blocks, new VFD's, new control voltage transformers, new dynamic brake resistors, new programmable logic controllers (PLC), new network switches, new fiber optic panels, and new control relays. New PLC installations require the contractor to provide PLC program development, licensed software packages, shop testing, and operator field tests. New VFD installations require specified hardware, programming software, onsite installation supervision by the VFD manufacturer, VFD test plans, and execution of performance verification tests. New control panel, graphic panel, and equipment panel installations require specified hardware to be verified through Government-witnessed shop testing prior to delivery to the work site. A critical element of the project involves complex sequencing and coordination of commissioning and cut-over of new equipment and systems, and highly technical interfaces between new and old systems. The Contractor must demonstrate experience and qualifications necessary to manage challenging Quality Control and Commissioning programs for both factory and on-site testing requirements. The project involves long lead time procurement of complex electrical and control equipment and fabrication of large mechanical gears. Complete on-site work in close coordination with the Government lock and dam facility, and minimize outages and disruptions to operations.

The Contractor must demonstrate experience and qualifications necessary to manage challenging Quality Control and Commissioning programs for both factory and on-site testing requirements. The project involves the procurement of complex electrical and control equipment with long lead times. Complete on-site work in close coordination with the Government lock and dam facility, and minimize outages and disruptions to operations. Provide on-site customer operations and maintenance training by authorized representatives of the new equipment manufacturers. Place of Performance is at the Ice Harbor Lock and Dam located near Burbank, Washington, Walla Walla County. Complete all work at the navigation lock within a finite work window of approximately 12 weeks between December 2016 and March 2017. Work must be completed within the specified work window in order to return the navigation lock to service in accordance with a coordinated Columbia/Snake River navigation system outage plan. Staff (supervision and labor) and provide on-site physical plant to support multiple daily work shifts to meet the requirements of the aggressive construction schedule constraints. All on-site work shall be performed in accordance with the Corps of Engineers Safety and Health Requirements Manual (EM 385-1-1). Solicitation is set-aside for small business concerns.
