- Description
- The U.S. Army Corps of Engineers Pittsburgh District has a need for a new interlock system located at three locks and dam facilities, Pike Island, New Cumberland and Hannibal on the Ohio River. The general scope of work includes an interlock system to incorporate the following required features: Valve-to-Gate Interlocks Gate-to-Valve Interlocks Valve-to-Valve Interlocks The Valve-to Gate interlocks shall only allow the filling valves to open if the downstream miter gates are mitered and shall only allow the emptying valves to open if the upstream miter gates are mitered. The Valve-to Valve interlocks shall only allow the filling valves to open if the emptying valves are closed and vice versa. Under normal operating circumstances, the filling valves and emptying valves cannot be open simultaneously. The Gate-to-Valve interlocks shall only allow the downstream miter gates to operate (open and close), if the filling valves are closed and shall only allow the upstream miter gates to operate (open and close), if the emptying valves are closed. In addition to the three types of interlocks mentioned above, under no circumstances can a set of miter gates be opened if the opposite miter gates are not closed. This situation may be physically impossible to achieve, but is still taken into account in the design of the interlocks. Interlock Control Panel The new interlock system shall consist of a centrally located interlock control panel for each lock chamber. The interlock control panel shall be the main control enclosure for the interlock control system. All limit switches on the miter gates, miter gate machinery, filling valves and emptying valves shall be hardwired to relays in the enclosure. The enclosure shall contain key operated bypass switches for each limit switch and shall indicate when a limit switch has been bypassed. When a limit switch is bypassed, a visual indicator shall flash to alert personnel of this condition. Visual indication shall consist of a red, flashing indicator at each location valves and/or miter gates are operated and on the interlock control enclosure. In addition to visual indication, an audible alarm shall be provided if a lock operation is interrupted or cannot be performed due to interlock permissives being violated. The audible alarm can be silenced, but will re-activate if the lock operation is continued and the fault condition still exists. Limit Switches New magnetic, leverless limit switches and wiring shall be installed at all locations. Limit switches required for the new interlock system consist of the following: Down Stream Mite Gates Mitered Down Stream Land Wall Miter Gate Machinery Closed Down Stream River Wall Miter Gate Machinery Closed Down Stream Land Wall Miter Gate Recess Down Stream River Wall Miter Gate Recess Emptying Valve Land Wall Closed Emptying Valve River Wall Closed Up Stream Mite Gates Mitered Up Stream Land Wall Miter Gate Machinery Closed Up Stream River Wall Miter Gate Machinery Closed Up Stream Land Wall Miter Gate Recess Up Stream River Wall Miter Gate Recess Filling Valve Land Wall Closed Filling Valve River Wall Closed Filling and Emptying Valve Controls The existing filling and emptying valve controls shall be rewired to interface with the new interlock relay control panel. All filling and emptying valves shall be controlled by momentary pushbuttons. Miter Gate Controls The miter gates are controlled by manually operated 4-way valves. The existing levers and 4-way valves shall be utilized and interfaced to the new interlock control system. Mechanical Modifications to Miter Gate Cylinders The mechanical work involves installing a custom blocking manifold in the A & B lines for every miter gate cylinder at three projects (Pike Island, New Cumberland and Hannibal). The manifolds will block flow of hydraulic fluid to/from the cylinders until the interlock control system simultaneously opens the valve for each line. This work should be done by a company that specializes in the installation and testing of hydraulic fluid power equipment. Magnitude of the project is between $1,000,000 and $5,000,000. Duration of project is 365 calendar days. The Invitation for Bid will be issued approximately June 18, 2012 on-line at the Federal Business Opportunities website; therefore requests for hardcopies of the specifications and drawings will not be honored. Requests must be made by registering for this IFB at http://www.fedbizopps.gov. Once registered, vendors, plans rooms and printing companies will be able to download this IFB on or after the above issuance date.
