Project Snapshot
The Port Authority of NSW refurbishment at Moores Wharf delivers a fully integrated mechanical upgrade across Ground Floor, Level 1 and Level 2 operational areas. The facility comprises marine administration workspaces, incident response rooms, fatigue rooms, IT spaces, locker rooms, simulator rooms, dining areas and amenities . The engineering objective was to provide zoned, high-performance environmental control suitable for mission-critical marine operations while integrating into an existing structure with varied ceiling heights and structural constraints. The system required: • Independent zone control across operational areas • Controlled outside air delivery via dedicated OAF risers • Lift shaft ventilation with temperature-triggered operation • Fire-rated duct penetrations and motorised dampers • Acoustic treatment of all FCUs and fans A Mitsubishi VRF heat recovery system was deployed, distributing refrigerant to multiple ceiling-concealed fan coil units across both levels. Dedicated outside air fans (OAF-2.1 & OAF- 2.2) provide tempered ventilation air to Ground and Level 1 systems . The scale of zoning, integration of risers, coordination with structural bracing, and acoustic constraints required careful services coordination as indicated in layout notes .
Our Role
- CCC Engineering delivered a staged electrical design service including:
- Design responsibility including final Statement
- Preparation of Shop Drawings and As Builts
- Equipment schedules, details, schematics, single-line diagrams specified.
- All services rooms, riser and equipment cupboard arrangements and layouts.
- All pipe, conduit, tray, catenary and duct route layouts.
- Coordinated and dimensioned drawing for each level of the building detailing all required
- penetrations and setout drawings for plinths and other traditional “builders” works.
- Coordination information giving detailed information regarding works specified in other
- sections of the project specification.
- penetrations for all services with the relevant input from the services specified herein.
Challenges & Solutions
