Manly’s iconic Shelly Beach has a beautiful new amenity building. Adriano Pupilli Architects designed it with user needs in mind, while Partridge engineers ensured a strong foundation despite the challenging soil conditions. Partridge’s team worked with the geotechnical engineer and water services coordinator to design the new foundations to suit the site conditions. The underlying soil conditions, consisting of fill overlying weathered sandstone, were factored into the design of a stiffened raft slab foundation over bucket piers founded in a medium dense sand layer. The project’s location demanded careful consideration of existing Sydney Water assets and guidelines to ensure a safe working environment and the protection of public infrastructure.
