This project is a new development to build a state-of-the art 8,000 square metre office building in Dunedin’s historical precinct. ACC Ōtepoti is a partnership between Ngāi Tahu Property and ACC Investments, designed by Warren & Mahoney Architects. Cosgroves worked closely with Ngāi Tahu Property, the architects and the construction team on a methodology to minimise disruption to neighbouring properties. As part of our design services, we were able to integrate Green Standard NABERS requirements into the building form which will provide high quality, energy efficient systems. Specific fire engineering design also allowed for an open public environment. Cosgroves civil engineers addressed the challenging 3-water infrastructure for the site.
The new office building was developed by CIAL for PGG. The offices are primarily open-plan, including conference facilities and meeting room clusters around the central open core. The building has been constructed to a very high standard with a number of sustainable features incorporated into the design. High performance low E double glazing with very well insulated walls and roof provide an energy efficient building envelope. Alternate engineering techniques enabled an open central core over two levels.
This high-profile Christchurch development required a sustainable A-grade design to create a modern, high-quality professional environment for top-tier anchor tenants; PWC and Chapman Tripp. Cosgroves were responsible for the complete design, documentation and construction monitoring of all electrical, hydraulic, and mechanical systems. The services design solutions were required to be extremely flexible to allow for tenant fit-out requirements. The PWC Centre was one of the first A-grade commercial projects to be constructed within the CBD after the Christchurch Earthquakes and innovation was a key part of the building’s success
The Waste Management Headquarters included 4,000m2 of commercial office space and 4,000m2 of industrial workshop facilities, as well as a large yard for bins and truck parking. Cosgroves provided environmentally sustainable design consultancy services targeting a Green Star rating for this complex and mixed-use site using a new rating tool that had not yet been adapted to the New Zealand environment during the design process. Cosgroves also actively participated in the VE process including re-design of the HVAC systems to meet budget while still meeting the sustainability goals of the project. Alternative fire engineering allowed for a double height open environment, to support the sustainability initiatives.
