Construction Contract: McNary Navlock Power & Controls Upgrade. This work is located at McNary Lock and Dam in Umatilla/Benton Counties near Umatilla Oregon. This will be a firm-fixed-price construction contract. The magnitude for this requirement is $10,000,000 to $25,000,000.

This project involves upgrading the McNary Navigation Lock electrical power and control systems. The Navigation Lock has been in service since 1954, and all the major electrical equipment is original. The electrical and control systems had a design life of 50 years, and now have the distinction of being the oldest systems in the Columbia-Snake River navigation system.

This project involves upgrading the McNary Navigation Lock electrical power and control systems. The Navigation Lock has been in service since 1954, and all the major electrical equipment is original. The electrical and control systems had a design life of 50 years, and now have the distinction of being the oldest systems in the Columbia-Snake River navigation system.

This project includes extensive electrical and control improvements to ensure the reliability and operability of the navigation lock for another 50 years. The scope includes providing new feeders from the powerhouse to the navigation lock; replacing the 480-volt power distribution equipment; installing cameras; repairing certain grounding details; and replacing the control systems for the downstream gate, upstream gate, drain valves, fill valves, and bascule bridge. It also includes replacing the upstream and downstream control stands for the navigation lock. The new oil-filled pad-mounted substation transformers will be located away from the river and will include spill containment systems. The following is a summary of the project scope from the Design Documentation Report.

Power

For the power distribution system, the scope includes replacement of the feeders from Station Service to the navigation lock; the step-down transformers; the navigation lock switchgear; the navigation lock motor control centers; the bascule bridge motor control centers; branch circuits; and branch circuit loads and panelboards that were or will be in the switchgear and motor control centers. The scope also includes replacement of corroded grounding electrode conductor connections within the navigation lock and the addition of ground busses to existing panelboards fed by the new equipment.

1. Feed power from Station Service to navigation lock at 13800V


2. Transform voltage down to 480V


3. Switch and protect power for MCCs


4. Feed power to motor control centers


5. Convert from ungrounded to high-resistance grounded 480V distribution


6. Switch and protect power for branch loads


7. Provide power to derrick crane

9. Provide power to existing non-motor loads, but not replacing lighting or lighting

Panelboards

1. Provide bridge motors and brakes


2. Provide VFD and FVR starter for downstream gate


3. Provide space for future VFD for upstream gate


4. Feed power to lock stand panelboards


5. Raceways and cable tray for wire and cable


6. Repair grounding electrode connections


7. Add ground busses to existing panelboards fed by new equipment


8. Demolish 2600-ft. of asbestos-cement cable trays


9. Demolish power center (with transformer) in Control Building


10. Demolish feeders from dam to power center


11. Demolish bridge motors and brakes


12. Demolish starters for downstream gate


13. Arc flash risk reduction with zone-selective interlocking

Controls

The scope includes replacement of relay-based control systems with PLC based control systems for the navigation lock miter gates; the bascule bridge; the drain and fill valves and a monitoring screen in the powerhouse control room; The scope also includes the operator interfaces; small craft stations; operator control consoles; and related field instrumentation. The scope also includes a new CCTV system for the navigation lock; marine radio in the lock stands; and network connections in the lock stands for VoIP and CorpsNet.

1. Bascule bridge control system. (HMI interface to be used as primary remote/local


2. controller: lever handle, push buttons to be used as local emergency backup controller)


3. Upstream gate control system (HMI interface to be used as primary remote/local


4. controller, lever handle, push buttons to be used as local emergency backup controller)


5. Downstream gate control system (HMI interface to be used as primary remote/local
