When it was completed in 1982, the William Clayton Building (now 133 Molesworth Street) in Wellington was the world’s first base-isolated office building. An upgrade has enhanced its earthquake resilience, and has some serious green credentials too.
Located on Wellington’s urban motorway is an engineering icon – 133 Molesworth Street. Its recent redevelopment enhanced the building’s earthquake resilience; reducing the impact of earthquakes and helping tenants get back to business as soon as possible after an earthquake.
The redevelopment also needed to deliver additional space, sustainability, and strong energy performance, while respecting the building’s original look.
It has. By adding two additional floors, the building doubled in size to 16,000m2. Sustainability was delivered through recycling the existing structure and original façade panels. Most of the building services were replaced with modern energy efficienct systems and, although the building has doubled in size, energy consumption has been reduced by a third when comparing the existing building performance.
The resilient building structure is base isolated and designed to remain largely undamaged, even during intense shaking. This was put to the test shortly after the completion of the redevelopment by the Kaikoura earthquake. The building successfully handled the full impact of the quake, meaning the tenant was back in the building the day after the quake – and the building was fully operational.
Despite a number of hurdles along the way (including the unexpected discovery of asbestos), the building was completed on time and to budget, thanks to close collaboration with the client, architect, and contractor.
