Engineering Urban Renewal: Ramsgate Park Masterplan (Kogarah)
Located at 152-206 Rocky Point Road, Kogarah, the site of the iconic former Darrell Lea chocolate factory has been transformed into a visionary masterplanned community. As the lead structural engineers for the developer (JQZ), JSBC Consulting was responsible for the structural design and delivery of this sprawling, high-density residential precinct.
This massive development encompasses 534 luxury apartments spread across four distinct high-rise building blocks, alongside a separate collection of 20 two-level terrace-style townhouses.
Delivering a project of this scale required JSBC to provide end-to-end engineering continuity—from the initial structural concept and detailed design through to on-site supervision and final completion. Here is how we engineered this landmark urban renewal project.
1. The Common Podium & Central Green Space
The architectural heart of Ramsgate Park is its beautiful, expansive green open space, designed to foster a strong sense of community.
Heavy Load Engineering: Supporting significant landscaping, deep soil profiles, and public walkways above a subterranean structure requires immense load-bearing capacity. JSBC engineered a highly robust common podium slab that unites the four apartment blocks. This massive structural “deck” safely captures the heavy dead loads of the landscaping while providing a secure, waterproof roof for the two-level basement below.
2. Mastering Structural Efficiency at Scale
When engineering 534 apartments across four distinct towers, any inefficiency in the structural design is multiplied hundreds of times over, costing the developer significant time and money.
Optimized Load Paths & Grids: To maximize construction speed and material efficiency, JSBC focused on highly optimized vertical load paths and standardized structural grids. By aligning the structural core walls efficiently from the roof down through the residential floors directly into the basement car park, we minimized the need for additional expensive, heavy transfer structures. This streamlined the work cycle for the builder, significantly accelerating the construction timeline.
3. Multi-Format Housing: Towers and Townhouses
A unique challenge of the Ramsgate Park masterplan was the integration of vastly different building typologies on a single site.
Structural Adaptability: While the four main blocks required high-rise lateral stability systems (core walls and shear walls) to resist wind loading, the 20 terrace-style townhouses required a completely different, lighter structural approach. JSBC engineered tailored load-path solutions for both the high-density towers and the boutique townhouses, ensuring every structure on the site settled and performed perfectly over the shared basement levels.
4. Unbroken Project Delivery
Unlike firms that simply hand over the concepts, JSBC Consulting remained deeply involved throughout the entire lifecycle of the Ramsgate Park development.
Site Supervision & Inspections: Building a masterplanned community requires rigorous quality control. Our engineers were consistently on-site, conducting critical inspections. This ensured that the built structure perfectly matched our high-performance design specifications, guaranteeing a safe, durable asset for the Kogarah community.
