Part 2 Heating, Ventilating & Air Conditioning (HVAC), Plumbing, Fire Suppression, and Mechanical D. Part 3 Not Used E. Contract Milestones and other General Provisions 1.02 RELATED DOCUMENTS A. Drawings and general provisions of the Contract Documents, and Division 1 Specification Sections including Specification Section Special Provisions, apply to this section PROJECT WORK COVERED BY ALL CONTRACT DOCUMENTS A. Work of the Project includes construction of Redundant SCADA Ethernet Network and the conversion of legacy Allen-Bradley PLC-3 system to Allen-Bradley ControlLogix PLC systems. The Work shall be performed for the CITY in accordance with the Contract Documents. The Work includes, but is not limited to, demolition, removal, replacement, installation of new equipment and/or modifications to existing equipment to the following areas and processes: North Pump Station New Grit Building Primary Sludge Pumping (E-Bldg) Return Activated Sludge (RAS) Building Secondary Sampling Building Secondary Effluent Disinfection Building Disinfection Chemical Storage Building Secondary Thickening Dewatering Server Room Dewatering Electrical Room Central Maintenance Facility Server Room Compressor Building Primary Skimmings Building SUMMARY OF PROJECT JULY 2012

7 Final Effluent Disinfection Building The Redundant SCADA Ethernet network requires a fiber optic backbone consisting of one 24- fiber cable. The fiber cable will make a loop or ring around the treatment facility. At each location where an Ethernet device or devices need to be connected to the network a Fiber Patch Panel and either a Field Network Cabinet (14 places) or a Server Switch Cabinet (2 places) must be installed. The Field Network Cabinets and/or Server Switch Cabinets require 120 Vac power. At each location a number of Ethernet devices will need to be connected to either Ring A, or Ring B, or both Ring A and Ring B. The network drawings show all devices connected to the Ethernet networks. The CONTRACTOR will route fiber through existing underground tunnels wherever possible using cable tray (preferred) or conduit. If the fiber ring is collapsed, meaning the to and from cable is run in the same cable tray the first fiber cable will be on one side of cable tray and the second fiber cable will be on the other side of the cable tray. If using conduits each fiber cable will be run in a separate conduit. Ring A fibers will be in one conduit and Ring B fiber cables will be in a separate conduit. If fiber path is to be routed outside conduits will be used. B. In the 1980 s a number of Allen-Bradley PLC-3s were installed to control the Treatment Plant. Over time most of these units have been replaced, upgraded and or modified in one way or another. This project will replace the remaining PLC-3s with Allen-Bradley ControlLogix or CompactLogix PLCs and any remaining Allen-Bradley 1771 IO will be replaced with ControlLogix PLC. The following list identifies what areas require new ControlLogix PLCs and/or CompactLogix PLCs: North Pump Station AOS-1 Panel Existing PLC-3 to be removed; a ControlLogix PLC has already been installed.
