New Zealand Building Code and Precast Concrete Standards

New Zealand precast projects may be subject to the New Zealand Building Code, applicable Verification Methods or Acceptable Solutions, project specifications and relevant New Zealand Standards.

PMtech develops detailing documentation with reference to the technical requirements applicable to each project.

NZS 3101.1 — Concrete Structures

NZS 3101.1:2006 — Concrete Structures Standard, Part 1: The Design of Concrete Structures, including applicable amendments, establishes requirements for the design of reinforced and prestressed concrete structures.

NZS 3101.1 is referenced by B1/VM1, the Verification Method for structural design under Clause B1 of the New Zealand Building Code.

Where applicable, project documentation can therefore be developed with reference to the relevant NZS 3101.1 requirements provided by the structural design and project documentation.

B1/VM1 — Structural Design of Buildings

B1/VM1 provides a verification pathway for the structural performance requirements of Clause B1 of the New Zealand Building Code.

The current version references the relevant structural design standards for building structures, including provisions applicable to concrete construction.

For precast projects, B1/VM1 may form part of the wider technical framework considered by the project’s structural design team.
