In a recent Auckland project Fletcher Reinforcing engaged early with the Alliance to look at providing new solutions for the challenge of splicing reinforcing steel up to the 40mm diameter that the engineers required. They were able to offer the Ancon BT metric threading system, which has been a proven system around the world for mechanical splicing and proven specifically in diaphragm wall applications in the UK over several years. This built on previous experiences in major infrastructure projects supplied by Fletcher Reinforcing in Auckland.

The Auckland Team at Fletcher Reinforcing embraced the challenges presented to them by the Alliance and the prefabrication yard in Otahuhu was buzzing with a large team of steel fixers working at speed in order to deliver to the required schedule. Once prefabricated, the cages were a regular sight leaving the Pacific Steel Mill early in the morning, led by pilot vehicles to escort them through the traffic. On site, Fletcher Reinforcing supported the Alliance by supplying its own team of steel fixers, removing unnecessary worry on the part of the project managers.

Both out at site and back at the production facility, health and safety was a major consideration. Some key learnings were developed through the project and any concerns were addressed quickly. Over 900 tonnes of New Zealand made Pacific Steel reinforcing bar was cut, threaded, coupled, fixed and fabricated into over 100 individual cages. The heaviest was 35 tonnes and approximately 31 metres long.

Matt Zame, Foundation Works Manager, The Well-Connected Alliance said, “Fletcher Reinforcing brought solutions to a very complex design of reinforcing cage and worked with our engineering team at every stage to ensure QA requirements were met fully. Any issues that occurred on site were addressed quickly with a ‘can-do’ attitude to avoid any negative impact. Even when program timeframes were reduced, the team at Fletcher Reinforcing cope well to adjust resources to ensure the project ran to plan. Overall, this was a well-run project by the Auckland team who showed a commitment at every stage to make sure that we achieved a result ahead of the original program.”

All the steel rebar supplied by Fletcher Reinforcing is produced in New Zealand by Pacific Steel. SEISMIC reinforcing bar, made by Pacific Steel, is made specifically to meet New Zealand’s unique seismic conditions and is found in commercial, industrial, infrastructure and residential buildings, so for more information on reinforcing bars, SEISMIC, reinforcing steel, reinforcing and reinforcing rods please go to  http://www.fletcherreinforcing.co.nz/page/max_frank/
