Reason for Change:
At eight lift stations, there is not enough available space within the existing telemetry panels to add the larger radio, power supply,
communications gateway, and other miscellaneous components. We propose to ugrade these sites by adding a small (16 "x16 "x8 ")
external enclosure to house these the components which will not fit.
At these six sites a new, 16 "x1 4 "x8" fiberglass telemetry panel will be built , installed, and wired: Baxter, Devil's Elbow, Kensington,
Lake Washington Flush, Long, and Stonegate.
At these two sites anew, 16 "x1 6 "x8" stainless steel telemetry panel will be built, installed, and wired: Lake Washington Beach and
New backpans will also be provided for temporary installations at two sites: East Renton and Lind.
At each of the eight sites with new panels, the following items will be needed: 4 feet of unistrut ($20), four to six conduit/ pipe clamps
($20), mounting bolts, nuts, washers ($5), conduit LBs, junctions, and covers ($10), conduit ($10), additional wire ($10),
Additional scope of work includes creating electrical schematics, panel layout drawings, purchase orders, Hardware Design
Submittals, wire label databases, UL listing documentation, along with the change control revision logs for each of these items.
Our engineers and managers also need to review the requested changes, understand the implications, archive the revisions as a new
