Subject: Questions and Answers RFQ Title: 19AS2025Q0027 – Supply & Installation of Eight (8) Condenser Water Pumps and Six (6) VSD/VFD Due Date: September 11, 2025, at 5:00 PM AEST

Question 1. Provide area maps/drawings.

Answer: Chilled Water System Drawings are provided as attachment.

Question 2. Include photos of the site.

Answer: Photos of the site are provided as attachment.

Question 3. What are the integration requirements for the pumps and VSD/VFDs?

Answer: The integration requirements are as follows:

Replacement of 6 pumps and 4 VSD/VFDs:

o Includes 2 primary pumps, 2 secondary pumps, 2 condenser water pumps, and their associated VSD/VFDs.

o These components will interface with the existing Carrier iVu BMS/BAS system.

Replacement of 2 pumps:

o Building P pumps (2 units) will remain connected to the existing Siemens

BMS/BAS system using standard BACnet/IP or Modbus TCP/IP protocols.

Replacement of 2 VSD/VFDs:

o These VSD/VFDs are currently connected to the cooling towers and will be replaced and integrated with the Carrier iVu BMS/BAS system.

Integration will require:

Assignment of unique network addresses for each VFD, chiller, and pump within their respective BMS/BAS network.

cooling tower fan.

BMS/BAS system for monitoring and control.

and feedback signals to their respective BMS/BAS system (Carrier iVu or Siemens).

Question 4.

Answer:

Primary Pumps:

o Power: 5 kW o Quantity: 2 units o Controlled by 2 VSD/VFDs

Secondary Pumps:

o Power: 30 kW o Quantity: 2 units

Condenser Water Pumps:

o Power: 5.5 kW o Quantity: 2 units o Controlled by 2 VSD/VFDs

Building P Pumps:

o Power: 0.75 kW o Quantity: 2 units (pumps only)

Cooling Tower VSD/VFDs:

o Quantity: 2 units

Ancillary requirements during pump replacement/installation:

Perform a basic assessment of future maintenance and serviceability of pumps, valves, and pipes during the project.

Provide a report on anomalies, including cavitation, corrosion, and scaling issues.

Check close-fully close and open.

Check strainers (isolate, pull strainer, and report any anomalies).

interfacing with the Carrier iVu BMS/BAS.

Check electrical wiring and VFD interface cables to ensure they are functioning within parameters and report to their respective BMS/BAS.

Installation Notes:

Pumps for each system must be fully tested after installation to meet the manufacturer’s requirements.

All VSD/VFDs must be programmed for the required minimum and maximum speeds according to the system design and interfacing with Carrier iVu.

Commissioning must verify proper hydraulic balancing, system pressures, and integration signals to their respective BMS/BAS.
