Located at 608 Mowbray Road, Echo represents the pinnacle of modern suburban living in Lane Cove. JSBC Consulting was engaged as the lead structural engineers for this premium mid-rise development, collaborating closely with acclaimed DKO Architects and premier builder Landmark Group to bring the project to completion.
Featuring 76 beautifully appointed apartments sitting above a two-level subterranean car park, this project required highly efficient structural solutions to balance DKO’s sophisticated architectural vision with Landmark’s rigorous construction timeline.
1. Urban Excavation on a Busy Corridor
Constructing a multi-level basement along a major suburban artery like Mowbray Road presents immediate logistical and geotechnical challenges.
Shoring and Retention: To safely achieve the two-level basement excavation, JSBC engineered a robust perimeter retention and excavation system. This shoring strategy was designed to safely support the surrounding infrastructure and roadways.
2. Structural Efficiency and Grid Alignment
In mid-rise residential developments, construction speed and cost-efficiency are heavily dependent on the structural grid. Heavy transfer slabs—which are often used to shift loads between mismatched residential and basement layouts—add significant cost and time to a build.
Optimizing the Load Path: Working closely with DKO Architects during the design phase, our team highly optimized the vertical load paths. By carefully aligning the core walls of the residential apartments directly over the core wakks of the basement car park, we minimized the need for complex transfer structures. This highly rationalized approach accelerating the construction schedule and driving down material costs.
3. Executing Architectural Excellence
DKO Architects are renowned for their highly articulated, modern facades. A building’s structural framework must provide an absolutely rigid foundation for these premium external finishes.
Deflection Control: To ensure the long-term integrity of the architectural facade and internal finishes, JSBC engineered the floor slabs and edge beams with extremely tight deflection limits. This precise structural detailing prevents the concrete from sagging over time, ensuring the building’s aesthetic features remain flawless long after handover.

Located just 150 meters from the bustling Crows Nest Village, “The Nines” brings contemporary, timeless living to Naremburn. Completed in 2020, this premium boutique development features nine luxury three-storey townhouses anchored over a shared subterranean basement.
JSBC Consulting was engaged to provide end-to-end structural engineering for the project—delivering everything from the initial structural concept through to rigorous site supervision and final inspections.
Here is how we engineered the structural backbone for this high-end residential build.
1. The Subterranean Foundation & Podium
Delivering a shared basement beneath a continuous row of multi-storey terraces requires strategic coordination to ensure the space is functional for residents. The upper levels of the townhouses were designed utilizing lightweight framing systems, which offer excellent construction speed and efficiency.
JSBC engineered the concrete basement podium to securely support this framing. The robust concrete mass of the podium provides a highly stable foundation for the residences above, while effectively maximizing the open space and turning circles required for vehicle access in the basement below.
2. Precision Execution & Site Supervision
Boutique developments demand meticulous attention to detail, not just in the design office, but on the construction site.
JSBC provided comprehensive site supervision and structural inspections throughout the build. Our engineers were on the ground ensuring that the concrete podium pours, structural walls, and framing connections met our exacting standards, providing the builder with the confidence needed to apply the high-end, timeless finishes that define the development.

Engineering The Lincoln: Mid-Rise Excellence in Caringbah
Located at 89-91 Willarong Road in the heart of the Sutherland Shire, “The Lincoln” offers highly convenient, contemporary living just moments from the Caringbah shopping precinct.
JSBC Consulting was engaged to provide the structural engineering for this premium mid-rise development. Designed by PBD Architects and delivered by premier builder Landmark, the fully completed project features 45 residential apartments across a five-storey building, anchored safely over two levels of underground basement car parking.
Delivering a multi-level basement in an established suburban environment requires a highly robust retention strategy. Here is how we engineered the subterranean framework and superstructure for The Lincoln.
1. Advanced Excavation: The Soldier Pile Shoring System
Excavating two storeys underground requires a retaining system capable of holding back lateral earth pressures to protect surrounding properties and infrastructure. For The Lincoln, JSBC engineered a highly efficient and robust soldier pile wall system.
Soldier Piles & Optimized Spacing: We designed the shoring system utilizing robust 600mm diameter concrete soldier piles. By analyzing the specific geotechnical conditions of the Caringbah site, we optimized the spacing of these piles at 2.4-meter maximum centers. This calculated spacing provided the necessary earth retention while minimizing unnecessary drilling and concrete costs for Landmark, driving commercial efficiency on-site.
The Capping Beam: A retaining wall is only as strong as its connections; if individual piles move independently, the wall can fail. To ensure the soldier piles act as a single, unified retaining structure, we engineered a 750mm wide by 500mm deep continuous concrete capping beam. This heavy-duty beam ties the tops of the piles together, preventing differential deflection and evenly distributing the lateral soil loads across the entire perimeter of the excavation.

2. Mid-Rise Structural Efficiency
Above ground, the focus shifted to structural efficiency and realizing PBD Architects’ contemporary design.
Seamless Load Transfers: Supporting five levels of residential apartments over a two-level basement car park requires careful alignment of the structural grid. JSBC engineered the vertical load paths to ensure the gravity loads from the 45 residences above transferred smoothly and safely into the basement columns below. This optimized structural grid maximized the turning circles and parking yield in the basement, ensuring a highly functional asset for the developer and a streamlined build for Landmark.
