City of Everett 01 11 00 - 14 <br />Port Gardner Storage Facility – Facility Construction Package WO# UP-3525 <br /> <br />01 11 00 - 14 SUMMARY OF WORK <br />Category 2: Sensitive information <br />Category 2: For official use only / disclosure permissible by law. <br />3) Process Mechanical <br />a) The EPS process mechanical components include pumping <br />equipment and the associated conveyance piping. Pumping <br />equipment for the lift station encompasses three submersible <br />style pumps, 60-P-0101 through 60-P-0103. These pumps <br />convey flow to a common 24-inch diameter header. <br />b) The pump installations include associated suction and <br />discharge piping, mechanical couplings, and isolation and check <br />valves. The discharge piping is 24-inch diameter and routed to a <br />high point located beyond the building envelop, north of the <br />structure, before routing below grade. <br />c) The EPS is connected to the Area 40 Stormwater Treatment <br />System and Area 50 Distribution structure by an upstream 36- <br />inch diameter pipeline and subsurface manhole. The 36-inch <br />diameter pipeline is connected to the southern end of the pump <br />station wet well. Mechanical work at the lift station includes <br />connecting this pipe to the lift station wet well. <br />d) The pump station includes a pedestal mounted pump suction <br />elbow constructed at the pump station deck. This will serve as a <br />utility station for mounting pumps during onsite service. <br />4) Electrical <br />a) EPS electrical infrastructure includes power three 45 <br />horsepower vendor supplied pumps. Each pump will be <br />controlled by an associated variable frequency drive. EPS <br />power will be routed from the Area 70 OMES building. <br />b) Power service to EPS includes service to the bridge crane and <br />trolly. This infrastructure includes a local disconnect, hand <br />station, and junction box. <br />5) Instrumentation and Controls <br />a) Installation and integration of the following Area 60 <br />instrumentation types into the site control system. <br />1. Radar level <br />2. level float switches <br />3. Pressure <br />4. Magnetic flow meter <br />b) Fabrication, programming, testing, and installation of custom <br />control panels, including Remote Input/Output (RIO) panel and <br />Operator Interface Terminal (OIT). <br />6) Site Civil <br />a) Excavation and fill for wet well construction. The project site is <br />known to have areas of high ground water therefore the EPS <br />excavation work will require dewatering. See Volume 7 <br />Attachment B, Geotechnical Engineering Report, for a <br />description of ground water conditions.
