BSG Property saw an opportunity with the Penang Marriott Complex development to create a landmark destination and elevate the city’s profile for living, business and leisure. Marking Marriott International’s 50th property in Malaysia to offer hotel rooms, apartments and residences, the development required seamless engineering to meet the brand’s global standards of luxury, performance and functionality.

BSG Property appointed our team as the civil and structural engineer for the 55-storey, 223-metre Penang Marriott Complex, which combines 223 hotel rooms, 90 executive apartment suites and 302 residential units. Drawing on our expertise in civil, structural, geotechnical and public health engineering, we created integrated design solutions that addressed the technical challenges of integrating three distinct components within a single tower. 

Strategically located along Gurney Drive in George Town’s vibrant tourist and commercial district, the development stands as one of the tallest towers in Penang that transforms the city’s skyline, meeting the growing demand for premium hospitality, enhances the visitor experience and supports Penang’s expanding tourism sector.

Engineering a complex tall building to offer integrated, luxurious services

Bringing together hospitality, residential and serviced apartment functions within a single tower required a high level of structural engineering integration and precision. We optimised the structural layout and introduced transfer structures to ensure balanced load distribution and stability across all functions.

To address site constraints, we developed a basement construction method using jacked-in spun piles as temporary king posts, later incorporated into the permanent structure. This allowed for safe and efficient excavation within a tight footprint.

Above the 450-person ballroom, we designed mega-trusses to support seven additional car park levels and facilities, creating large column-free spaces without compromising structural integrity.

Reducing material waste, cost and carbon footprint

Sustainable design was embedded into the project from the outset. By optimising the structural design, we maximised material efficiency without compromising the building’s strength or lifespan, reducing both environmental impact and construction costs.

We also integrated temporary works into the permanent structure, significantly cutting waste and resource use. For example, diaphragm walls and ring/strut slabs provided vital construction support while enhancing the tower’s long-term stability. This approach minimised the need for temporary supports, reduced disruption to the surrounding environment and lowered overall material consumption.

We wanted to bring together luxury hospitality, serviced apartments and residences under one roof — and Arup’s integrated engineering solutions made it possible.
