Residential building

The project comprised a residential development incorporating timber, steel, and concrete structural systems to support both architectural design intent and functional living requirements.

Key structural components included:

• Timber wall framing, floor framing, and roof framing systems
• Reinforced concrete footing system supported by geotechnical investigation
• Structural steel beams and columns to support open-plan layouts
• Precast concrete wall elements where required
• Roof deck design including structural support for balustrades
• Stormwater management system integrated with site drainage

The project required addressing several structural and coordination challenges:

• Integration with existing structure, requiring assessment of load transfer and compatibility between new and existing systems
• Large openings and open-plan layout, necessitating steel beams and lintels to achieve architectural intent without excessive deflection
• Mixed material systems (timber, steel, precast, concrete) requiring coordinated detailing and load paths
• Roof deck and balustrade support, introducing additional lateral and point loads at roof level
• Foundation design dependent on soil conditions, requiring coordination with geotechnical inputs
• Stormwater management integration, ensuring drainage design aligns with structural and site constraints
• Construction sequencing considerations, particularly where new works interface with existing building elements

A coordinated structural design strategy was implemented to address the project requirements:

• Developed a hybrid structural system, combining timber framing for efficiency with steel members for long-span and high-load areas
• Designed reinforced concrete footings based on soil conditions to ensure adequate bearing capacity and settlement performance
• Incorporated steel beams and lintels to support large openings and maintain open-plan layouts without intermediate supports
• Engineered roof framing and roof deck structure, including provision for balustrade loads and lateral stability
• Coordinated connection details between timber, steel, and precast elements to ensure structural continuity and constructability
• Assessed and integrated existing structure, ensuring safe load transfer and compatibility with new works
• Aligned stormwater design with structural layout, ensuring effective drainage without compromising footing performance

• Achieved architectural flexibility with large open-plan spaces
• Delivered a cost-effective hybrid structural solution tailored to residential construction
• Ensured safe integration with existing structure, reducing construction risk
• Provided efficient and buildable detailing, supporting smooth construction sequencing
• Enhanced long-term performance through robust footing and drainage design
• Enabled future adaptability of internal spaces
