CMI Advisory Notice: Report Validations, Performance Requirements & Engineering Assessments, CodeMark NZ Template & Evaluation Reports.

Subject: Evidence of Compliance – Report Validations

CMI wishes to advise all our valued clients of the following requirements in relation to evidence of compliance.

It is the responsibility of the Certificate Holder to make sure that all the evidence supplied to CMI in support of your accreditation is up to date, verifiable and completed by accredited &/or competent persons.

In most cases testing bodies place a validity period on their reports. This means that reports that are approaching the end of this period will require revalidation by the testing authority. Where testing bodies do not place a validity period of testing reports, CMI suggest the testing be validated by the testing authority every 5 years, regardless of whether the testing standard has changed. This may be for a number of reasons, but generally, where the test standards remain current, it is to ensure that the test lab maintains its support of that testing.

In the case of Engineering Reports these need to be kept up to date given the changes in the standards and building codes. To ensure that you are keeping your testing current and Engineering Report, Technical Appraisals etc. current, CMI requests that all of our clients review their current testing and determine if any of the test reports or Appraisals/Evaluations require validation.

It is important to note that, in most cases, the testing body merely needs to issue a validation of the original test, this can normally be done quite quickly by the issuing body. Engineers and technical bodies will similarly re-issue their report having conducted a review of the material.

When conducting annual surveillance and accreditation audits, CMI will be advising Certificate Holders if we note testing that is due for revalidation. CMI believe the above direction is fair and reasonable and shows us that you keep current and up to date records and provide the expected Quality Assurance of your product in the market.

Subject: Performance Requirements & Engineering Assessments

In light of the changes to the Building Code and increased surveillance, moving forward, there will be a need for Engineering Report and Evaluations to be provided in support of any Performance Requirements of the BCA or NZBC being claimed. Please note, this is not a requirement for Deemed to Satisfy (DtS) provisions of the BCA in most cases. An example where an Engineering Report would be required for both the DtS and Performance Requirement is Structure. Clients will be required to engage the services of a suitably Qualified Engineer to assess the test data and report on the product/system’s compliance with the relevant building code and confirm the applicable clauses, inclusive of sub-clauses.

CMI may be able to assist in recommending Engineering firms for this work. Please notify us should you require this assistance.

Subject: New Zealand CodeMark Certificate of Conformity (CoC) Template

As of mid July, CMI has been given the approval to amend the single page CodeMark New Zealand CoC template to an extended template that CMI have produced in line with the CodeMark Australia template. The additional real estate allows us to address matters we previously were unable to on the template supplied to Certification Bodies; such as detailed information on product/system components, tested specimens and subsequent results, evaluation methods etc.

Subject: CMI Evaluation Reports issued in conjunction with CodeMark

Given that the function of the CMI Evaluation Reports was to fill the gaps between the lack of information on the old format CodeMark CoC templates, CMI, upon consultation, has determined that having both the new format CodeMark CoC and an Evaluation Report in the market place will lead to confusion, consequently as the CodeMark CoC is now carrying the same information that the Evaluation Report would have contained, the Evaluation Reports, as related to a CodeMark CoCs, have become redundant. Consequently, CMI will not be issuing Evaluation Reports in conjunction with CodeMark CoCs and will be withdrawing any applicable Evaluation Reports. The above will become effective upon issue of your CodeMark onto the extended template CoC. Following this date, the Evaluation Report will be withdrawn and must be removed from advertising and other company literature.

For those clients who would still prefer to have an Evaluation Report, CMI will be happy to supply one, however this will require a new application and will be subject to Surveillances and Renewals similar any other Scheme offered by CMI.

CMI would like to thank our Clients for their understanding in the above matters and request that should clarification be required in relation to any of the above, please reply via email: office@certmark.org.

Testing requirements under the Building Code of Australia (BCA) – CodeMark Australia, Type Test & WaterMark

The review of the BCA 2016 Amdt 1 has resulted in the redefining of what constitutes an Accredited Testing Laboratory.

Under the requirements of BCA Volume 1, Part A1, the following definition is now stated:

CMI has been in conversation with both NATA and the ABCB and wishes to advise the following:

Any testing undertaken, to be used as evidence of conformity against the BCA, MUST BE conducted by a NATA or ILAC accredited testing body, with the test standard under its scope.
CMI WILL NOT accept testing from testing bodies that do not meet this criteria and nor should any Engineering Firms.

Clients are advised that they must be mindful of this when commissioning test reports. The test lab should be asked to provide a copy of their scope, referencing all of the test standards they are proposing to test the product against. Alternatively, you can search the scope of the laboratory on either the NATA web site https://www.nata.com.au/accredited-facility/ or through a mutually recognised accreditation body from another country https://ilac.org/signatory-search/, such an IANZ in New Zealand http://www.ianz.govt.nz/directory/.

Please note, in many cases, testing bodies who are not accredited will produce test reports with a disclaimer, usually; “this report is not to be used for regulatory purposes”. Such reports can not be used as evidence of compliance against the BCA.

Clients currently proceeding through Initial Certification, Certificate Changes, Surveillance Audits or Renewals, will be notified of whether any reports supplied are not valid, otherwise, CMI request that each Client complete a review of their supporting documentation and ensure that all testing  and Engineering Evaluations have been conducted in line with the above prior to your next audit activity.

If you have any questions, please email office@certmark.org or contact your Client Manager.

CMI Advisory Note: Product Certification vs. System Certification.

certmark-int-180

CMI has recently sought advice from the ABCB regarding the referencing to test results of products that have been tested in concert with other building materials to achieve specific compliance values.

For example, a wall sheeting material that has been tested for its acoustic and insulation values in a wall assembly that incorporates the sheeting, Rockwool insulation, an air gap and plasterboard.

Such an assembly may well achieve a R value of 50 + and comply with the requirements of the Building Code. However; if the CodeMark™ application for certification is for the wall panel, as a “product”, and not for the wall panel as a “system”, then the certificate of compliance cannot reference the R values achieved by the “system”.

In the case of a “product” certification, only the values actually achieved by the “product” that forms the subject of the certification can be attested to on the certificate of compliance.

If the application is for a “system” then the “system” certification must clearly identify the components that go into making up the system. For example:

The XYZ wall system consist of the following:

Product Description
XYZ wall panel The XYZ wall panel is a 12mm fibre cement wall panel.
Top Hat The Top Hats have a nominal width of 35mm
Framing Steel framing conforming to NASH Standard/Timber Framing to AS1684
XYZ Rockwool 75mm XYZ Rockwool
XYZ plaster board 10mm XYZ plasterboard
Fasteners & Fixing Fixing of Top Hat to steel framing; 10-16x16mm Hex Head Teks screw
Fixing of XYZ wall panel panels to Top Hat from inside of buildings 14-10x65mm Hex Head Type 17 Screw
XYZ Adhesive XYZ Adhesive is used for gluing the panels together at vertical and horizontal joints.

 

It is important to note that certification of a building system requires the Certificate Holder to accept responsibility for the other components used in the system. Such components must be clearly defined in the Certificate Holders version controlled installation manual or guide. Any installation of the certified system that varies from the description on the Certificate of Conformity (CoC) will be considered to be non-compliant in line with CMI’s Terms and Conditions and the Scheme Rules.

If you require further information on the above or clarification on any other aspect of the CodeMark Scheme, please contact your CMI Client Liaison Officer.

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.
