Christchurch Civic Building wins 2012 Supreme Concrete3 Sustainability Awards
Athfield Architects has taken out the 2012 Supreme Concrete3 Sustainability Award for its extensive refurbishment of the new Christchurch Civic Building on Hereford Street.
The award, presented at the annual New Zealand Concrete Conference in Hamilton on Friday evening, recognised the transformation of what was the New Zealand Post Building into an architectural statement that adds tremendous value to Christchurch, says Cement and Concrete Association of New Zealand (CCANZ) chief executive Rob Gaimster.
The judging panel applauded Athfield Architects for the way in which significant changes were made to the existing concrete building, creating spectacular work and interactive spaces without losing the original architectural and industrial heritage.
“This is a truly outstanding example of adaptive reuse, one which demonstrates the flexibility of concrete as a sustainable construction material. It continues the emerging trend in New Zealand of optimising resources and enhancing the built environment through the innovative refurbishment of our existing concrete building stock,” judges say.
The design reconfigured the building’s existing service and transportation cores, and added mezzanines to the main office levels. The existing precast concrete cladding panels from the southern facade were removed, reworked and reused on the northern side to create a completely new extension with double skin facade, and circulation stair and winter gardens behind.
Despite the significant changes, the design retains and celebrates the building’s original Brutalist style. “The new construction materials read deliberately as distinct insertions, to set up a contrast between old and new, providing visual interest and complexity.”
The Christchurch Civic Building is the first to receive a 6 Green Star Office Design rating, further testament to the project’s successful outcome.
On their way to the top prize, the Athfield Architects team were also presented with the Excellence in Commercial Concrete Construction.
The Awards are part of the Concrete3 initiative launched in 2007 by CCANZ and acknowledge projects, products and initiatives which demonstrate excellence in environmental, economic and/or social sustainability for the built environment.
Other category winners
The awards also produced winners in four other categories for projects which excelled in different areas of sustainable concrete construction.
Excellence in Concrete for the Community went to Tennent + Brown Architects for Nga Purapura in Otaki. Te Wananga-O-Raukawa, a Maori tertiary institution, required a building to fulfil its vision for courses focused on improving physical well-being for Maori.
The project strategy involved the extensive use of resilient precast concrete as the primary cladding material. Produced locally, using Otaki gravel, pre-tensioned precast concrete provided a reduced construction programme and minimised lifecycle costs through its durability in a coastal environment.
The building’s most striking feature is the sandblasted patterns on the exterior panels, which communicate the project’s Kaupapa of Māori health and well-being to the wider community.
Excellence in Concrete Innovation was awarded to Allied Concrete Limited for its Recycled Glass Sand Initiative. The company has converted three of its plants to be able to use crushed glass as a sand replacement in a selection of lower strength concrete mixes.
The environmental benefits resulting from the kerbside collection, processing and use of waste glass in concrete include landfill life extension, reduced transportation of recycled materials and conservation of natural resources.
Excellence in Civil Concrete Construction was won by Fulton Hogan Limited for the Huntsbury Reservoir in Christchurch. Following the February 2011 earthquake, which severely damaged the reservoir and resulted in the total loss of stored water from the 35,000m3 structure, the reinstatement of as much water storage as feasible was urgently required.
The design and construction method adopted allowed for the reuse of the existing concrete external walls, roof slab, foundations and floor slab of the existing structure, as well as work to add seismic resilience. The reuse of demolition concrete waste was crucial to the material minimisation plan with concrete crushed on site and reused as fill in various locations.
Excellence in Residential Concrete Construction was awarded to Ponsonby architecture company Matter for a premier residential property on a picturesque but steep site in Point Chevalier, Auckland.
The foundations and the house structure are built around a concrete raft slab and sandwich panel arrangement, with the raft slab offering seismic resilience while also being a key element of the overall passive solar design.
The mass of the sandwich panels also help to prevent dramatic fluctuations in the house’s internal temperature, while providing retaining capability for the site.
Simplicity of design has been realised through the intelligent use of versatile concrete to create a stylish and functional family home on a difficult site.
21 Queen Street wins 2011 Supreme Concrete3 Sustainability Award
21 Queen Street, Auckland. A benchmark for adaptive reuse
Peddle Thorp Architects has won the 2011 Supreme Concrete³ Sustainability Award for its work revitalising the multi-storey office building at 21 Queen Street, Auckland, preserving its concrete frame and core while creating vibrant and thoroughly modern spaces both inside and out.
The award, presented at the ninth International Symposium on High Performance Concrete Design in Rotorua, recognised the ‘reuse – reduce’ strategies adopted by the project principals, which enabled the building’s life cycle to be significantly increased, the embodied energy of its concrete elements to be saved, and the emissions associated with alternative demolition and new build scenarios prevented – all key to achieving environmental sustainability in construction.
Stripping the site’s 14 level 1970’s concrete structural frame of its cladding and fit-out, to form the heart of a refurbished and modern building also underpinned the project’s commercial viability, as well as breathing new life into the urban environment around Queen Elizabeth Square.
Announced in Rotorua on Wednesday 10 August, the Awards, part of the Concrete³ initiative launched in 2007 by the Cement and Concrete Association of New Zealand (CCANZ), acknowledge projects, products and initiatives which demonstrate excellence in environmental, economic and/or social sustainability for the built environment.
On their way to the top prize, the team behind 21 Queen Street also received the Excellence in Commercial Concrete Construction award.
Through 'reuse and reduce’ 21 Queen Street meets all aspects of sustainable construction
CCANZ chief executive Rob Gaimster said that through the reuse of a concrete frame building the project met all the economic, social and environmental imperatives of sustainable development, elevating it above a host of outstanding entries in 2011.
“This example of adaptive reuse will quickly become the New Zealand benchmark for what can be achieved in terms of optimum resource management, (embodied) energy efficiency and design potential, through the imaginative redevelopment of our concrete structures.”
Other Category Winners
The awards also produced winners in four other categories, for projects which excelled in different areas of sustainable concrete construction.
Excellence in Concrete Innovation went to engineering firm Structex for the Southern Cross Hospital’s Endoscopy Building in Christchurch, which for the first time in New Zealand utilised post-tensioned concrete PRESSS (PREcast Seismic Structural Systems) technology with U-Shape Flexural Plates. This innovative approach to structural engineering and construction saw the medical facility, which has a Building Importance Level 3 classification, emerge unscathed from the February 22 earthquake.

2010 Concrete3 Sustainability Award Winner Announced
A special concrete mix designed by Fletcher Construction as part of the Tauranga Harbour Link has won the 2010 Supreme Concrete³ Sustainability Award, presented at the New Zealand Concrete Conference.
Mix "M" at the Tauranga Harbour Link: Stage 2
Designated “Mix M”, the resulting concrete is designed to survive 100 years in harsh marine conditions, and was employed extensively in Stage 2 of the Harbour Link project to form beams used in the off-ramps, bridges and land spans.
Mix M achieved top honours in concrete sustainability for its specially blended and extensively trialled mix of Golden Bay cement, fly ash (a waste product from coal burnt at Huntly Power Station), and microsilica 600, which enabled demanding durability, high early strength, and high workability requirements to be met.
The use of fly ash and microsilica resulted in a significant reduction in cement requirements and a corresponding reduction in the carbon footprint of the concrete beams.
Announced in Wellington last Thursday (October 7) the awards, part of the Concrete3 initiative launched in 2007 by the Cement and Concrete Association of New Zealand (CCANZ), acknowledge projects, products and initiatives which demonstrate excellence in environmental, economic and/or social sustainability for the built environment.
On their way to the top prize, the team behind Mix M also received the Excellence in Civil Concrete Construction award.

Research Demonstrates Importance of Cement & Concrete to NZ Economy
Research into the importance of the cement and concrete industry to New Zealand’s economy has found it contributes nearly $3 billion towards GDP.
A New Zealand Institute of Economic Research (NZIER) report shows that for the year ending March 2006, the value of the industry’s output was $7.4 billion. This activity supported 24,000 jobs and created a value add of $2.8 billion – about 2% of New Zealand’s GDP.
The report was commissioned by the Cement & Concrete Association of New Zealand (CCANZ). CCANZ chief executive Patrick McGuire said the research illustrates just how significant the cement and concrete industry is to the nation’s economy.
“A primary aim for us is to ensure that cement and concrete are truly sustainable – environmentally, socially and economically. The NZIER research proves the industry is more than meeting the economic part of this objective,” Mr McGuire said.
