Vol 2 - Garney Construction

d. Reconnect all existing active signals to PLC-8001 and connectPLC-8001 into plant network. New signals will be connected andprogramming performed as Work proceeds.e. A maximum duration of 7 calendar days will be allowed in whichPLC-8001 can be out of service.5. Polymer Room Addition:a. Perform required site demolition, excavation and surfacepreparation as required to install concrete foundation piers.b. Demolish portions of building indicated. Provide suitabletemporary protection against weather, dust, and constructiondebris. Submit protection plan to Owner and Engineer forapproval. Provide temporary heating, if required, to maintain roomtemperature above 55 degrees F.c. Install under slab piping and construct building foundation andbase slab concrete, masonry/brick walls, roofing system andaccess doors to provide a complete building enclosure.d. Install dry polymer feed system (bulk bag frame/volumetricfeeder, mixing tanks and transfer pumps) in new Polymer RoomAddition. Polymer feed to two belt filter press units must bemaintained at all times except for deviations as described herein.1) Contractor may use the new polymer feed system totemporarily feed polymer solution to the belt filter pressequipment provided it provides the same capability andredundancy as the existing polymer system, and theContractor operates the system in the temporary mode andthe temporary arrangements are acceptable to the Owner andEngineer.e. Demolish existing polymer feed system and associated piping asshown on Drawings.f. Install permanent polymer feed system (aging tanks and centrifugeand belt filter press polymer feed pumps). If Contractor utilizesbelt filter press polymer feed pumping equipment in a temporaryarrangement, relocation of applicable pumping equipment to finallocation as shown on Drawings shall be limited to no more than1 day with 2 weeks prior notice provided to Owner and Engineer.6. Belt Filter Press No. 3 and Related Systems - Milestone 4 (300 Daysfrom Notice to Proceed):a. Install supplemental columns as shown on Drawings. Temporarilyrelocate and reconnect piping/conduit as required that is in conflictwith proposed column locations.b. Install BFP 3 curbs and structural supports.c. Install all piping (sludge feed, washwater drain, filtrate, planteffluent water and polymer solution) associated with Belt FilterPress No. 3.PROJECT COORDINATIONPW/WBG/38205901 31 13 - 6 AUGUST 15, 2012©COPYRIGHT 2012 CH2M HILL
