3 The New Zealand Building Code (NZBC) is a schedule to the Building Regulations
1992. It provides requirements for compliance with the Building Act 2004 when constructing a new building or altering an existing one. The Building Code sets out performance standards that building work must meet and covers aspects such as structural stability, fire safety, access, moisture control, durability, and services and facilities.
4 This unit standard applies to sheet roof membrane composed of rubber such as
Ethylene Propylene Diene Monomer (EPDM) that usually is installed over plywood or concrete substrates on low slope roofs. This unit standard does not apply to liquid membrane or torch on membrane, for which other unit standards are available.
5 Definitions
Alternative solution
– a building design solution that differs totally or partially from those contained in the Acceptable Solutions, but still meets the performance requirements of the Building Code. It can be a minor variation from a Compliance
Document, or a radically different design and construction approach.
Company requirements – include the policy, procedures, and methodologies of the company. They include requirements documented in company and site health and safety plans, quality assurance documents, and contract work programmes;
EPDM – Ethylene Propylene Diene Monomer, a thermosetting synthetic rubber used as a resilient part of a sealing washer, or as a roof membrane.
Industry use – common use in the roofing industry.
Job specifications refer to the documented information found in construction drawings, project specification documents, legislation, regulations and codes.
Manufacturer recommendations – refer to product information and product data sheets provided by the manufacturer of any given product.
Notifiable work is as defined in A Guide to the Health and Safety in Employment Act
1992 (Wellington: Department of Labour, 2003); available at http://www.osh.govt.nz/order/catalogue.

Please note
Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.
