Bypass bridge steel found to fail tests in New Zealand

Breaking_News_LogoA article has been published by Radio NZ today that sixteen hundred tonnes of steel from China has been found to be too weak.
This steel was to be used for four bridges on the $450 million Huntly bypass that forms part of the $2 billion Waikato Expressway.

Contractors building the ‘Road of National Significance’ chose a very low bid for the steel tubes.

But the test certificates for them have turned out to be wrong, and now an expensive fix-up job is under way.

The contractors, Fulton Hogan and HEB Construction, have admitted to RNZ News the steel tubes were not good enough. They did not comply with standards for structural steel, which for bridges were very high as they must resist impacts, heavy loads and low temperatures.

It was only after a third lot of testing that the contractors found out. The first tests were done in China by the steel mill and the tube manufacturer; it is understood the second tests were done in New Zealand on samples sent here from China.

Both lots of tests said the steel met the New Zealand standard….

Method Building Systems and The Block

Everyone has either seen or heard of the TV show, The Block.

Today Method Building System released an articles on how the 2012 winner of The Block is now using Formance Structural Insulated Panels (SIPS) to build his dream home in Castor Bay Auckland with his fiancé Kylie.

Smart, energy efficient, and providing additional space, it’s not surprising this savvy duo chose to build with Formance. And it’s great to have them on board.

Their unique design features a living pod and a sleeping pod on either sides of a creek, connected by a glass corridor.
The speed of construction, coupled with the huge insulative qualities that are achieved with Formance, convinced Ben to use this superior building method.

To meet with Ben and talk about his experience and insights, please join us at Buildnz Designex, ASB Showgrounds, Auckland at site 200, June 21-23, with some special offers and a pretty interesting display.

Types of Modern Construction

Modern methods of construction (MMC) are now used across the construction industry, and particularly to build new homes. MMC offer potential savings in time and materials and can provide higher standards of quality than conventional construction methods. Off-site assembly means quicker erection on site and the ability to achieve a weather-tight construction within a shorter period of time.

While off-site construction is generally well managed and auditable, there are a number of additional factors that those using MMC must bear in mind. With traditional building methods, certifiers have developed a good understanding of the associated risks. This is not the case with many new methods, and although the risk of systemic failure is low, the consequences could be severe. Insurers therefore seek to ensure that systems are correctly certified, and that they are manufactured and built in line with that certification.

MMC typically fall into the following categories:

  • Volumetric or modular construction involves the off-site production of three-dimensional units. Modules may be brought to site in a variety of forms, ranging from a basic structural shell to complete rooms with internal and external finishes and services already installed.
  • Panelised systems involve the off-site production of panel units, which are assembled on site. The panels may consist of wall, floor or roof units, sometimes referred to as cassettes.

Closed panel units may be built of timber, steel frame or concrete panels. Lining materials and insulation are installed in the factory. Panels often include services, windows, doors and finishes.

  • Open panel systems do not include elements such as insulation, lining boards or vapor control layers. These are applied to the frame system on site, together with external cladding and internal finishing. Careful control of on-site finishing is therefore required, and the panels must be protected against the elements until weather-tight.
  • Site-based structural systems, such as insulated concrete formwork, are not considered to be manufactured off-site. These systems require third-party approval to secure a warranty, and their acceptability relies heavily on the procedures in place to ensure correct installation on site.

With MMC, the construction, design and layout of a typical system is planned in advance and a “design freeze” is imposed before factory production begins.

Testing is often needed to ensure that standards for durability and weather-tightness can be achieved.

To obtain approval by a building certifier, MMC systems must:

  1. Meet the requirements of relevant local building codes, or international equivalents current at the time of application.
  2. Be covered by a current approval from an independent third-party technical approval body. Details of the testing body’s accreditation will need to be supplied to the certifier, together with the certification document.
  3. Have been subject to independent third-party testing that identifies equivalent local test standards have been verified. Details of performance and the limitations of use must be provided.

At CertMark, we operate the CodeMark™ certification scheme, which is recognized by the Australian and New Zealand governments and allows MMC providers to show evidence that their systems are fit for purpose. This scheme removes the requirement for individual site assessments in place of a general certification.

The importance of correct test results

Certification can be a lengthy and drawn out process that can cost time and money to not only your organisation but your customers as well. To help keep this at bay there are helpful pointers that can be addressed before commencement of Accreditation. One of which is knowing the importance of correct test results.

What happens if I don’t have testing?
We are CertMark understand that not all products have testing conducted and as such we have staff members on deck that can write ‘Scope of Testing’. These documents actually specify what testing is required for your specific product.

I have testing, but I don’t know if it’s the right testing
For test data to be accepted for the Accreditation it has to be conducted by either NATA or ILAC accredited laboratories and testing facilities. This is keep consistency within the Scheme with the products being certified. If you have testing data and you are unsure if it is eligibility please contact one of our staff members to assist you.

I have test data, but it’s from another country. Can this be used?
With majority of our Clients importing from other countries, it’s no surprise that there may be no Australian or New Zealand test results conducted on the product. This does not mean that you are required to re-do the testing, in fact the Scheme was developed with this in mind, as well as the specific idea of new and innovative products that don’t necessarily have standards or clause in Australia and New Zealand and as such Testing Data from the respectable countries may be complicated to come by. Testing data from other countries is used and compared to what the standards would be in Australia by our Technical Experts and Engineers.

Contact Us
We at CertMark understand that the whole Certification process can be daunting and as such we have a team waiting to answer your questions in relation to certification.
If you would like to speak with a Team Member please contact our office or email info@CertMark.org.

We look forward to hearing from you!
