NBN ISO 20887:2021

This document provides an overview of design for disassembly and adaptability (DfD/A) principles and
potential strategies for integrating these principles into the design process. This document provides
information for owners, architects, engineers, and product designers and manufacturers to assist
in their understanding of potential DfD/A options and considerations, and for other parties who are
responsible for financing, regulating, constructing, transforming, deconstructing, or demolishing
construction works.
This document is applicable to all types of buildings (e.g. commercial, industrial, institutional, and
residential), civil engineering works (e.g., dams, bridges, roads, railways, runways, utilities, pipelines)
and their constituent parts. It can be used for new construction, refurbishment and renovation, and in
the design of incremental improvements in, or complete redesign of, buildings, building systems, civil
engineering works, and their constituent parts.
This document also provides guidance on measuring performance regarding each DfD/A principle and
related objectives.
This document is intended to be used in conjunction with and following the principles set out in
ISO 15392 and the ISO 15686 series.
This document does not set specific levels of performance for the disassembly or adaptability of
constructed works, however, it does include requirements that are mandatory for the implementation
of specific DfD/A principles that are applicable when these principles are adopted.
