More recently, Aecom picked up work on the new central library, which aims to "create a city hub for knowledge, heritage material and an area for recreational reading".
However, Hubbard says it is important not to neglect the wider focuses of the rebuild. He cites the capacity building work at the Port of Lyttelton - an often-forgotten but vital contributor to Christchurch's economy. Despite damage to the port, exports from the surrounding regions have actually increased over the past two years placing additional strain on the existing infrastructure.
"When we look at the overall picture, it's about people, and rebuilding a city for the people of Christchurch," Hubbard says. "I don't think there's any silver bullet ... Getting residential people back in their homes has to be a priority."
There are also impacts for the consultancy. Says colleague and technical director Peter Harris, "We've been able to create a really good and unique atmosphere.
"Because we've got a lot of people coming from elsewhere, your team becomes a lot closer, because your work colleagues become your friends. That's certainly helped us in terms of the culture we've created."
Last year, Aecom launched Agropolis, as part of a collaborative initiative between FESTA, Garden City 2.0, Aecom, A Local Food Project, Juliet Moore, Andreas Wesener (Lincoln University), Liv Worsnop (Plant Gang) and Rosie Brittenden (Christchurch Youth Council). The project aims to create a scalable and productive farm in the heart of the CBD, composting waste from local restaurants, and growing food products which can then be returned to the community.
In the long-term the aim is for Agropolis to become an urban food hub, including a mobile kitchen to be used for "garden-to-plate" experiences and educational programmes.
Corporate social responsibility initiatives such as Agropolis can draw on the strong sense of community among Christchurch residents and businesses. "It's really about bringing the community together," says Hubbard: As we rebuild the city, it's not just having a city full of buildings, it's about having a city that people can live in as well."
