It is important to ensure that all personnel on site have access to accurate, up to date technical information on the many products, materials and equipment used on a project. In most cases individual products are not used in isolation, but form part of a building process. Also a particular manufacturer's and/or supplier's requirements for handling, storage, preparation, installation, finishing and protection of their product can vary from what might be considered the norm. Access to technical information can help overcome this potential problem.
Provide a material manufacturer/supplier warranty:
25 years | For materials - Limited warranty for residential applications only |
5 years | For materials - Limited warranty, for all other applications |
Refer to the general section 1237 WARRANTIES for additional requirements.
Modify or expand the clause to suit project or manufacturer/supplier requirements, options include:
Provide an installer/applicator warranty:
2 years | For installation |
Refer to the general section 1237 WARRANTIES for additional requirements.
Modify or expand the clause to suit project or installer/applicator requirements, options include:
Refer to 1270 CONSTRUCTION for requirements relating to qualifications. Installers must have watched and read the Forte installation guide prior to installation.
This clause includes generic text which should be expanded only if there are specific qualification requirements.
Substitutions are not permitted to any of the Millboard® specified systems, components or associated products listed in this section.
Provide Millboard® Installation and Maintenance Guide document before Practical Completion of the contract for issuing to the building owner.
Provide the following compliance documentation: -
List the Producer Statements - Construction (PS3) required from installers that are required as a condition of carrying out this work.
List also Producer Statements - Construction Review (PS4) required from consultants to be engaged by the Contractor.
Producer Statement - Design (PS1), may be required where certain design work is undertaken by the Contractor or manufacturer / importer / distributor.
This guidance note describes the use of Masterspec slip resistance clauses. The extent of slip resistance clauses included within this section is subject to Q&A and section requirements. Ensure the section 1278SR SCHEDULE OF SLIP RESISTANCE TESTING is included in the specification.
NZBC D1/AS1, Table 2 identifies walking surfaces that are level or sloping access routes (including stairs) under dry and wet conditions that either:
Note:
Exceptions to wet slip resistance requirements for level access routes (refer NZBC D1/AS1, 2.1.2) include:
Walking surfaces comply with NZBC D1/AS1, Table 2 for slip resistance requirements and are exempt from testing.
Check project walking surfaces against Table 2 to confirm acceptable solution relates to project requirements. Identify compliant walking surfaces if this section also includes surfaces to be tested, or surfaces previously tested.
The following walking surfaces have previously been tested for slip resistance, and comply with NZBC D1/AS1 requirements.
Millboard® Decking has been tested to AS/NZS 4586 Dry Floor Friction Test and obtains a coefficient of friction of greater than 0.4 COF.
Millboard® Decking has been tested to AS/NZS 4586 Wet Pendulum Test and obtains a slip resistance value of greater than 39 SR
Refer to the www.forte.co.nz for test results for the various Millboard decking ranges. Generally the coefficient of friction is between 0.58-0.66 COF and the slip resistance value is between 51-54 SRV.
Expand clause to nominate surfaces, test methods, test results and location of test results, e.g. attached within the specification Contract Appendix.
This clause allows for the identification of surfaces that have been tested by manufacturers/suppliers, or where test results have already been obtained for the surface.
