G Boiler Electrification

Overview The Gordon Institute of TAFE in Geelong is calling for suitably qualified persons to tender for boiler replacement works at its Geelong Campus, 2 Fenwick Street, Geelong, Victoria. The works comprise Building G Electrification and Main Switchboard Upgrade. Scope The scope includes: Stage 1: Enabling Works Complete pre-read measurements, procurement and preparatory works, including ground-level thermal storage tanks, pumps, HHW pipework rough-ins, supports, valves, controls interfaces, electrical provisions and associated builders work, while maintaining the existing HHW system Carry out pre-read measurements of the three existing HHW pumps (flow rate, shut-off head, suction and discharge pressure) prior to any demolition works and submit results to the engineer for review Supply and install new ground-level plant associated with the new HHW system, including two thermal storage tanks Install ground-level insulated HHW pipework, insulation, supports, valves and external cladding associated with the thermal storage and pumping arrangement Rough-in HHW flow and return pipework from the ground-level plant area towards the rooftop HHW plant connection points Coordinate and complete builders work associated with Stage 1, including penetrations, supports, set-out, access provisions, temporary protection, weatherproofing and make-good associated with the ground-level plant and pipework rough-in works Maintain existing HHW system operation during Stage 1, and cap, label, secure and protect all incomplete pipework and services ready for Stage 2 and 3 connection Install preliminary mechanical, electrical and controls provisions associated with Stage 1, including conduits, cable pathways, control interfaces, equipment isolators, sensor provisions and wiring provisions required to support later connection, controls integration and commissioning Stage 2: Rooftop Demolition and Platform Works Decommission, demolish and dispose of existing rooftop equipment in accordance with AS2601 and AS5149.4, including cranage, isolations, structural, acoustic, penetration and make-good coordination Decommission and dispose of three redundant rooftop boilers, three HHW pumps, associated pipework, flues, valves, controls, wiring, switchgear and ancillary services during the agreed summer shutdown period Dispose of demolished equipment and materials in accordance with The Gordon's requirements for recycling and salvaging, and provide receipts from recycling and salvaging of material to the client Make safe, demolish and remove all redundant wiring, controls and switchgear Provide all cranage, rigging, lifting studies, permits, traffic management, pedestrian management, exclusion zones and temporary protection required for the safe removal of rooftop equipment and materials Coordinate the demolition sequence and platform works with the Structural Engineer Coordinate and complete builders work associated with redundant penetrations, redundant flues, roof openings, plinths, supports and make-good works, with all redundant penetrations made weatherproof and reinstated to maintain existing building fabric performance Stage 3: Heat Pump Installation, Connections and Commissioning Install the new rooftop heat pump plant and associated HHW equipment, complete mechanical, electrical and controls connections, integrate meters and BMS points, and undertake flushing, testing, commissioning and performance verification to place the new HHW system into full operation Supply and install eight Modular Air-Sourced Heat Pumps (Carrier HWC-H7001HV, to be procured by the Client and novated to the Contractor) complete with 50mm deflection spring mounts and 8-10mm deflection rubber Supply and install ten primary circulating pumps in duty/standby configuration, complete with 50mm deflection spring mounts, 8-10mm deflection rubber and maximum 1440rpm motor rotational speed Supply and install two secondary HHW pumps in duty/standby configuration, complete with 50mm deflection spring mounts, 8-10mm deflection rubber and maximum 1440rpm motor rotational speed Install insulated rooftop ductwork as shown on drawings, complete with weatherproof flashing Supply and install expansion vessel, chemical dosing equipment, auto-refill arrangement, valves, strainers, test points, thermometers, pressure gauges, supports, controls interfaces and all ancillary items required for a complete installation Supply and install insulated HHW pipework, headers, valves, fittings, supports and external pipework cladding to connect the thermal storage loop and field loop, providing a complete and fully operational system Install valves, sensors, controls, electrical and antivibration spring mounts and all ancillary elements required to furnish a fully operational system Supply and install new mechanical services switchboard (MSSB-1) on the new platform as shown on drawings, providing power for all new plant, including connection to the existing submain Supply and install new thermal energy meters as indicated on the drawings Connect, program and trend meters on the BMS Complete BMS integration, controls programming, graphics, alarms, trends, metering and functional control sequences for the new heat pump plant, ground thermal storage plant and associated pumping arrangement Complete make good works Complete weatherproof sealing and painting of penetrations Carry out electrical isolations and modifications to electrical systems and switchboards as required Allow for all asbestos related removal and treatment works associated with the project works Complete system testing and commissioning, including final pipework pressure testing, flushing, cleaning, chemical treatment, filling, venting and balancing of the complete HHW system prior to plant start-up, with commissioning results submitted to the engineer for review and approval Mechanical, Electrical Install the new mechanical services switchboard to suit the new HHW plant, including connection to the existing submain Provide cable trays, cable ladders, supports, conduits, switchgear and control gear, auxiliary panels and enclosures and all ancillary equipment to complete the installation Install earthing systems to all accessories, equipment and switchboards in accordance with AS3000 and AS2067, in coordination with the Builder Provide general power associated with mechanical services equipment, complete with RCD protection as required and in compliance with AS3000 Confirm switchboard labelling and finish with the Architect/Client Provide an electrical meter in the new switchboard, complete with Bluetooth connectivity Provide all equipment with local electrical isolators Ensure all electrical works comply with AS3000 Ensure all motors are high efficiency, minimum IE3 classification Information Requested Tender Option 1: Heat Pump Reduction Credit Provide credit pricing for a reduction in the number of heat pumps, subject to confirmation of the required heating capacity following review of thermal metering data Tender Briefing A briefing session will be held for the G Boiler Electrification tender.
