Objectives of the HVAC Upgrade:

• Improve indoor air quality and ensure consistent thermal comfort throughout all seasons.

• Enhance the safety and well-being of all hall users.

• Future-proof the facility by increasing its flexibility to support a broader range of community uses and events.

Scope of Work

1. Decommissioning and Disposal of Existing System

• Safely remove and dispose of the existing evaporative cooling units and wall-mounted electric heaters in accordance with environmental regulations and relevant Australian standards.

• Seal and flash all roof penetrations left by the removed evaporative systems. Roof flashing works must meet Australian building and industry standards and extend fully to the roof ridges to ensure weather-tight integrity.

2. Design and Engineering

• Develop a compliant Heating, Ventilation, and Air Conditioning (HVAC) solution tailored to the thermal load and operational needs of the B.I.U. Band Hall.

• The design must:

- Comply with the Building Code of Australia (BCA) and relevant Australian Standards.

- Account for the following site-specific conditions:

• The hall has no existing insulation, and the walls are constructed from precast concrete.
• Data from the Bureau of Meteorology indicates that maximum temperature that has been recorded in Broken Hill is 46.3°C and the minimum temperature is -2.9°C.
• The hall is primarily used for band practice and community events.
• The space has a maximum occupancy of 80 people.

3. Installation

• Install the new HVAC system with minimal disruption to hall operations and building occupants.

• Complete any necessary electrical infrastructure upgrades to accommodate the new HVAC equipment.

• Ensure the new system is installed as per the approved design and manufacturer specifications.

4. Testing, Commissioning, and Calibration

• Fully test and commission the newly installed HVAC system to confirm operational performance.

• Ensure the system meets relevant indoor air quality standards.

• Calibrate all equipment to deliver optimal temperature regulation based on seasonal variations and usage patterns.

5. Documentation and Handover

• Provide all required documentation, including:

• Electrical safety certificates.
• Warranty details for both equipment and installation (minimum 12-month warranty required).
• Operating and maintenance manuals.
• As-built mechanical and electrical drawings and schematics.
