Professionals integrate this document into their workflow by referencing it during the early design stages to ensure compliance with local accessibility requirements. It is typically used alongside CAD or BIM software when detailing staircases, ramp profiles, and door clearance zones. Designers should cross-reference these guidelines with specific project site conditions to confirm that all proposed access routes meet the defined performance criteria before submitting for building consent or peer review processes.

This technical guide is a mandatory resource for any building project located in New Zealand, spanning residential homes, commercial office buildings, retail spaces, and public infrastructure. It is critical for architects, interior designers, and MEP engineers working on projects that require universal design and barrier-free access. Professionals use this to validate circulation layouts, specify compliant handrail heights, and determine ramp slopes. It is an indispensable asset for ensuring that all architectural designs meet the necessary legal standards for public health and safety.
