- Project Overview:
This Central Coast duplex development combines architectural elegance with structural precision, designed to suit the unique site conditions. The project prioritizes durability, efficiency, and compliance with Australian Standards and the National Construction Code (NCC). - Foundations & Substructure:
- Reinforced concrete strip footings and slab-on-ground construction, designed per AS 2870.
- Geotechnical site analysis ensures appropriate site classification, bearing capacity, and soil reactivity allowances.
- Waterproofing and damp-proof membranes protect habitable ground-level areas.
- Superstructure:
- Load-bearing system incorporates reinforced concrete, structural steel framing, and masonry walls for stability and load transfer.
- Suspended floors include reinforced concrete slabs and engineered timber joists to achieve acoustic separation and long-term serviceability.
- Lateral stability is maintained with structural shear walls and bracing elements, compliant with AS 1170.2 wind loading requirements.
- Roof & Upper Levels:
- Curved roof and parapet supported by structural steel beams integrated with reinforced concrete slabs.
- Lightweight framing elements in partitions and roof reduce dead loads while maintaining performance standards.
- Facade & External Features:
- Curved balconies and shading fins use reinforced concrete cantilever slabs and concealed steel framing for structural integrity and architectural finesse.
- Vertical stone-finished central wall serves as both a design feature and a load-bearing element.
- Screening and vertical batten elements are supported by secondary framing fixed to the main structure.
- Materials & Durability:
- Reinforced concrete designed for coastal exposure (B2/C1) ensures resilience against marine conditions.
- Structural steel is hot-dip galvanized and coated for long-term corrosion protection.
- Masonry and concrete are detailed with control joints and reinforcement to minimize shrinkage cracking.
- Services Integration:
- Concealed service penetrations for stormwater, electrical, and mechanical systems are incorporated without compromising structural capacity.
- Termite protection systems installed per AS 3660.
- Compliance & Standards:
- National Construction Code (NCC) Vol. 2
- AS 3600 – Concrete Structures
- AS 4100 – Steel Structures
- AS 1684 – Timber Framing Code
- AS 2870 – Residential Slabs and Footings
- AS/NZS 1170 – Structural Design Actions
Key Takeaway:
A Central Coast duplex development where modern architectural design seamlessly integrates with robust structural engineering, ensuring long-term durability, aesthetic appeal, and full compliance with Australian standards.
