NT Deemed to Comply Manual

Background

The NT Deemed to Comply Manual (DTCM) is referenced in the Australian Building Codes Board (ABCB) Housing Provisions (HP).

Products contained in the DTCM have been determined by the committee to meet the required structural resistance of materials for construction in high wind areas (ABCB HP part 2.2 structural provisions).

Manufacturers' specifications must be consulted for any non-structural issues such as waterproofing, safety etc.

Where drawings for a product or system comprise multiple sheets, these will be indicated as sheet 1 of 3, sheet 2 of 3 and so forth.

Note that drawings marked as withdrawn are provided for reference only as they are no longer approved for use on new structures. Products or systems may have been withdrawn at the request of the manufacturer or because contact information has not been updated with the committee.

A list of products added or removed over the past 3 months is provided on the search screen. To see a list of all products which have been withdrawn, select the status 'withdrawn' without any information in the other fields.

Applications for inclusion in the NT DTCM

Applicants, please note

Although the committee makes every effort to process applications for inclusion in the Deemed to Comply Manual as quickly as possible, the process is time-consuming both for applicants and committee members and the process takes at least 6 months from application to final decision.

To reduce delays, all applicants should ensure that their applications are complete, product sheets are prepared in accordance with the guidelines (with notes, limitations etc in the appropriate place on the sheet, and all supporting documents - in particular test results) are provided.

On receipt, all applications will be given a preliminary review to ensure that the layout is in accordance with the committee’s requirements. Mistakes identified at this stage will need to be corrected before the application is referred to the committee.

Any errors noted by the committee will need to be corrected and the sheets re-certified before the sheets can be approved for inclusion in the manual.

Applicants must ensure that all details, references tables and calculations are correct before the sheets are certified and it is the responsibility of the certifying engineers to check that all details, references, tables and calculations are accurate before the sheets are signed and submitted to the committee.

All applications for inclusion of products/systems must be made on the approved form and lodged with the committee, together with all required supporting documentation.

Important

Please note:

Product sheets must be in the approved format and provided at A3 size.
Applications should be clearly addressed to the committee. If you are lodging applications in person, please ensure that they are in an envelope and handed directly to the registrar.
If you are lodging applications by email, send to the registrar at bas.dtcm@nt.gov.au.
The process of approval for a product in the Deemed To Comply Manual is unlikely to be completed in less than 6 months from receipt of the application.

Retesting of metal roofing products

The 'Low High Low' pressure sequence testing regime was introduced in the BCA 2006 from 1 May 2006 as the official testing mechanism for all metal roof products, cladding assemblies, connections and immediate supporting members, replacing the 10,000 cycle test used previously.

Since that time, the NT has dual referenced the 10,000 cycle and Low High Low systems to give industry the opportunity to move to the new testing regime. This dual referencing ended on 30 April 2009 and all products not supported by Low High Low pressure sequence test results were withdrawn from the manual.

From 1 May 2009 any product to be retained in the manual must be tested under the new regime (Low High Low) and the test results submitted to the committee for consideration, as part of a complete new application. Where extrapolation of results is required, this should be provided in writing by the testing authority.

In accordance with BCA clause 3.10.1.0 (f) and table 3.10.1, all sheets referencing Low High Low testing should include reference to Australian Standard AS1170.2 and no reference should be made to AS4055.

Testing facilities

Testing facilities for metal roofing products under the Low High Low system are available at various testing centres in Australia and New Zealand.
