Ararat Double-Storey Alterations & Additions Structural Design
Inverloch Double-Storey Timber Framing Project
Location: Inverloch, Melbourne
Project Type: Proposed Construction of a Double-Storey Single Dwelling
Project Scope
Fundament was engaged to design the timber framing structure for a double-storey residential dwelling in Inverloch, Melbourne. The project required an efficient, cost-effective structural system that could support large spans and wide openings while maintaining stability and compliance with Australian standards.
Challenges
- High-Span Structural Requirements: The design included large open spaces that required careful load distribution
- Cost Optimization: The goal was to utilize timber framing instead of alternative high-cost structural materials
- Stability Considerations: Ensuring adequate lateral and vertical support for long spans and openings
- On-Site Construction Deviations: The as-built structure differed from the original engineering drawings, requiring a structural review
- Compliance with Australian Standards: Adhering to AS 1684 (Residential Timber Framing Code) for safety and durability
Our Solution
Our structural engineers developed a timber framing strategy that successfully addressed the challenges while optimizing costs. Key solutions included:
✅Optimized Beam and Column Placement: Ensured structural efficiency by strategically distributing loads while maintaining open spaces.
✅Reinforced Timber Framing: Used LVL (Laminated Veneer Lumber) and engineered timber beams to support high-span areas.
✅Cost-Effective Structural Design: Eliminated the need for excessive steel framing, reducing material costs while maintaining strength.
✅Bracing and Load Distribution: Integrated shear walls and bracing elements to enhance stability and wind resistance.
✅Assessment of Modified Construction: Conducted a detailed structural evaluation of the modified parts of the build.
✅Rectification Work: Developed a practical structural solution that ensured the stability of the project while minimizing unnecessary work and costs.
✅Compliance with AS 1684: Ensured the framing system met all regulatory requirements for residential timber structures.
Outcome & Benefits
✔Cost Savings Achieved: Timber framing reduced construction costs without compromising stability.
✔Efficient Structural Performance: Successfully accommodated large spans and big openings with a lightweight yet durable design.
✔Structural Integrity Restored: The rectification work guaranteed compliance and long-term structural adequacy.
✔Optimized Stability: The structure maintains long-term integrity and load distribution efficiency.
✔Regulatory Compliance: Met all Australian timber framing standards (AS 1684).
Ararat Double-Storey Alterations & Additions Structural Design
Location: Ararat, Victoria, Melbourne
Project Type: Structural Design for Alterations & Additions to a Double-Storey Building
Project Scope
Fundament was engaged to provide the structural design for alterations and additions to a double-storey building in Ararat, Melbourne. The project involved removing internal walls in the basement, modifying the first-floor layout, and designing additions supported by a Bondeck slab, along with balcony extensions over the ground floor.
Challenges
- Basement Wall Removal: Assessing the impact on structural stability and designing alternative load paths.
- First-Floor Additions: Ensuring the new layout and extensions were structurally sound.
- Bondeck Slab Design: The additional slab weight needed to be properly supported by the existing structure.
- Existing Footing Evaluation: Checking whether the footings could handle increased loads from the new additions.
- Non-Standard Column Sections: The client requested the use of non-standard steel sections, requiring detailed capacity verification.
- Temporary Propping: Considering safe propping methods during slab construction to prevent structural instability.
Our Solution
Our structural engineers developed a reinforcement strategy that ensured the integrity of the modified structure while optimizing material use. Key solutions included:
✅Basement Structural Reinforcement: Designed load transfer solutions to compensate for removed walls.
✅Optimized Bondeck Slab Design: Ensured the slab weight was adequately distributed through the existing structure.
✅Existing Footing Assessment & Strengthening: Verified footing capacity and proposed reinforcement where necessary.
✅Capacity Verification for Non-Standard Columns: Conducted structural analysis to confirm suitability for load-bearing applications.
✅Safe Temporary Propping Strategy: Developed a temporary propping plan to support the structure during construction.
✅Compliance with Australian Standards: Ensured adherence to AS 3600 (Concrete Structures) and AS 4100 (Steel Structures) for safety and durability.
Outcome & Benefits
✔Safe & Efficient Basement Modifications: Load redistribution maintained structural stability after wall removal.
✔Well-Supported First-Floor Additions: The Bondeck slab and balcony extensions were properly reinforced for long-term performance.
✔Optimized Use of Non-Standard Sections: Engineering analysis ensured structural adequacy of client-specified columns.
✔Secure Construction Process: Implemented temporary propping solutions to maintain safety during construction.
✔Regulatory Compliance: Fully met Australian structural engineering standards.
