times can be reduced by 20 days to six days, allowing existing digesters to successfully treat up to 300% of the nominal design wastewater inflow. machining services such as custom electrical housing machining, complex multi-axis machining, thin-walled carbon-fibre mould tooling, press tooling, micro components, manifolds, prototyping, plastics machining, BEST OF THE BEST The innovation received the Ronald Hicks Memorial Award from Water New Zealand in 2010 and an ACENZ Innovate NZ award in 2015. production, communication facia and ultra-lightweight product machining. “Through it the company makes the parts other companies don’t even attempt,” he concludes. www.engineeringnews.co.nz 31 CALIBRE CONSULTING Calibre Consulting is a leading provider of professional infrastructure and built environment solutions across a wide range of markets.  In the waste to energy space it offers specialist services to help implement residue to revenue system designs to improve operational performance and efficiency of existing wastewater treatment plant assets and sludge digesters. It focuses on biogas from organic waste which is used worldwide for the production of power, heat and transport biofuel.  This is a key technology for a low carbon future in New Zealand and the world.  Calibre’s ‘digester booster’ innovation - developed in 2008 - is operational at full-scale biosolids digesters located at municipal wastewater treatment plants.  The innovation gives the plant operatorsthe option to improve the biosolids throughput and biofuel production of existing digesters by up to 300% - and without the construction of new digesters.  The key to increased treatment capacity is the separation of digester hydraulic and solids residence time by internal recuperative thickening. This saves the plant owner $2 to $3 million per installation, and hydraulic residence CONTOUR ENGINEERING Contour Engineering specialises in a variety of fields that require exactitude from medical, surgical and aerospace to defence, aviation, avionics, carbon fibre mould tooling, digital navigation, automation work cell building and automated equipment. “Often much of what the company does cannot be talked about let alone find grace among the pages of 'Engineering News' as a result of the high level of secrecy involved and the need for the companies it represents to protect intellectual properties and innovative technologies,” points out owner Roland Auret. He emphasises though that the company’s proven ability to deliver excellence in precision engineering by manufacturing quality products enables its customers throughout New Zealand to push the boundaries of innovation and take their products to the world. This, he says, is facilitated by the latest in CNC machining in the company’s workshop. “To support our vision we have a suite of hi-tech machines that allow us to output the highest-quality machined components.” In addition Auret says the company has expanded its capability with the installation of a new 5-axis Doosan DNM350/5AX that he describes as a “perfect fit”. He explains that it has contributed significantly to Contour being able to offer COOK COSTELLO An expert in the multi-faceted disciplines of civil, structural, and geotechnical engineering, architecture and surveying, Cook Costello has strategically grown its geographical reach. Currently it operates out of four cities including Christchurch, Auckland, Whangarei and Wellington. Recently it was awarded the ‘merit award’ at the 2016 Innovate New Zealand Awards for ‘Sapper’, a custom built foundation solution and costing tool developed for a client’s complex and evolving needs. As a result of its focus on building depth into teams and creating a sharing economy between multiple offices, the company benefits from an integrated and interactive approach to its work. Its mantra, another key point of difference, is ‘local expertise, national resource’. This has resulted in the company’s work on projects - ranging from light commercial through to high-end bespoke homes – attaining renown for diversity and versatility. “We pride ourselves on being a one-stop shop. A client can come in with an idea or a concept and we have architectural draughting capacity as well as structural, civil, geotechnical and environmental expertise on all our sites,” says Cook Costello receiving its ‘merit award’ at the 2016 Innovate New Zealand Awards project manager Dean McFarlane. “What this means is that we can offer greater continuity and a more cost- effective service.”
