PSE were appointed to provide structural design services for a single storey rooftop extension to an existing block of residential units.
Construction comprised of a light-weight timber frame structure consisting of stud-walls and timber floor joists.
The proposed residential units were located above an existing two storey reinforced concrete frame comprising of basement parking and retail space and an additional two storey of existing residential units.
The project presented the challenge of appraising the existing structure for the additional load from the proposed rooftop extension. The PSE team overcame this by a combination of structural surveys, diligent desk study and finite element modelling of the existing structure.
