Full title and description

AS 3850.3:2021 Prefabricated concrete elements — Part 3: Civil construction. Requirements for the planning, design, manufacture, casting, transport, erection, temporary supports, grouting and incorporation of prefabricated concrete elements used in civil, infrastructure and non‑building construction.

Abstract

AS 3850.3 sets out technical and safety requirements specific to prefabricated (precast) concrete elements used in civil and infrastructure works. The standard covers responsibilities and documentation through the design, casting, handling, transport, rigging and erection phases, and addresses temporary supports, bracing, fixing, grouting and inspection to ensure safe manufacture and incorporation of elements into permanent works.

General information

• Status: Current (in force at publication).
• Publication date: 25 June 2021.
• Publisher: Standards Australia.
• ICS / categories: 91.100.30 — Concrete and concrete products.
• Edition / version: Second edition (2021).
• Number of pages: 71 pages.

Scope

The standard applies to prefabricated concrete elements used in civil, infrastructure and non‑building construction and provides requirements affecting safety in planning, manufacture, design, casting, transportation, erection and incorporation into the final structure. It complements the other parts of the AS 3850 series and addresses both permanent and temporary conditions that affect element integrity and site safety.

Key topics and requirements

• Design stages and documentation requirements for manufacture, transport and erection.
• Erection design, stability during erection and temporary support design.
• Design considerations for lifting, rigging and selection/specification of lifting and bracing inserts (including reuse and post‑installed fixings).
• Wind and other design loads relevant to handling and erection phases.
• Concrete strength specification, casting practices and quality control.
• Transport, cranage and rigging procedures including typical rigging configurations.
• Temporary bracing, propping and inspection requirements while elements are being installed.
• Fixing, grouting, tolerances, levelling pads and removal of temporary supports.
• Inspection, damage assessment and repair guidance for prefabricated elements.
• Normative and informative appendices covering drawing information, roles and responsibilities, lifting design process and typical rigging configurations.

Typical use and users

Used by civil and structural engineers, precast manufacturers, transport and crane contractors, site contractors and erectors, building certifiers and inspectors, project managers and purchasers involved in design, manufacture, transport and installation of precast concrete elements for infrastructure and non‑building projects.
