56 The Terrace


S&T are the building services engineers for the Kiwi Property Group (KP) $67M major upgrade of 56 The Terrace, Wellington.

The property comprises two adjoining properties: an 18-storey office tower constructed in the mid-1960s; and the seven-storey Aurora Chambers, constructed in the mid-1970s. The Aurora Chambers building will be demolished and replaced with a new and extended eight-storey building, linked in with the main Tower building to form large open floorplates of up to 1,800m2.

The structural upgrade and modernisation of the approximately 24,500m2 NLA building to an A-Grade standard commenced at the end of 2014 to reposition this prime location for occupation by the Ministry of Social development (MSD); due for completion in mid-2016. The building will operate as predominantly office space but will also accommodate retail spaces on the ground floor.

S&T provided professional engineering services for both the base build and new interior fit out, working in close collaboration with the respective KP and MSD project teams of architects, engineers and project managers.

New high performance double glazed windows replace the ageing façade. 3D modelling of the building by S&T aided the façade design through simulation and analysis of the building fabric thermal performance, occupant comfort, and energy performance for a typical year.

Design also included new services for mechanical, electrical, lighting, data provision and fire protection services throughout. The previously unprotected building will be fully sprinkler protected. Extensive building information modelling (BIM) was critical to create a coordinated layout that encompassed the imposed spatial, structural and seismic constraints.
