How certificates of work and producer statements work togetherįor residential work, licensed building practitioners (LBPs) must produce a certificate of work (CoW) for engineering design of the primary structure (including foundations). Guidelines: Using producer statements on the Engineering New Zealand website has information on what to include in a producer statement. It's important that producer statements for Design (PS1) or Design Review (PS2) detail the specific clause(s) of the Building Code that the design complies with, and how it complies with the Building Code (for example, Acceptable Solution or Verification Method, MBIE guidance and/or specific engineered design). Information needed in a producer statement You will need to ensure the contractor’s engagement includes the need to provide the producer statement at the completion of the work. The council should be clear about when they expect to receive producer statements during the building consent process.
PS 3 – Construction (often used by the installers of proprietary systems).There are currently four types of producer statements, in use. Councils will use their judgement and internal processes when considering producer statements and how much weight to give them. Aspects of this work will be outside the council’s in-house expertise and a producer statement can assist the council when they are determining whether the building work complies with the Building Code. Producer statements are typically used for specialist work, such as engineering, or where there is a proprietary product which is installed by appointed contractors.
In considering whether to accept a producer statement, a council will normally assess the credentials of the author to ensure that person has the appropriate experience and competence in their particular field of expertise. They are used as one source of information which the council may rely upon to determine whether there are reasonable grounds to conclude that building work complies with the Building Code. While producer statements are well-established and widely used, they have no particular status under the Building Act 2004.
The producer statement system is intended to provide Building Consent Authorities (BCAs) with reasonable grounds for the issue of a Building Consent or a Code Compliance Certificate, without having to duplicate design or construction checking undertaken by others. It is not a product warranty or guarantee of compliance. A producer statement is a professional opinion based on sound judgment and specialist expertise.
