AS 3850.3:2021 pdf Prefabricated concrete elements Part 3: Civil construction
1 Scope and general
1.1 Scope
This document provides requirements which impact on safety for planning, manufacturing,
construction, design, casting, transportation, erection and incorporation into the structure of
prefabricated concrete elements in civil, infrastructure and non-building construction. It applies to
prefabricated concrete elements, including but not limited to pipes, culverts, bridge elements, tunnel
elements, poles, piles, drainage and sewerage access and maintenance chambers, manholes, pits, lintels,headwalls, covers and surrounds, and water quality products.
This document does not cover the in-service design of these elements.
Additional requirements for some products are covered in other Standards.
This document does not cover the following:
(a) Elements used in building construction.
(b) Small individual concrete elements able to be handled manually (e.g. bricks, blocks, pavers).
