Full title and description

AS 3850.2:2024 — Prefabricated concrete elements, Part 2: Building construction. This Standard sets out requirements that affect safety and reliability in the planning, design, casting, manufacturing, transport, cranage/erection, temporary support, fixing/grouting and final incorporation of prefabricated concrete elements used in building construction (walls, columns, beams, floors, façade panels and similar).

Abstract

Part 2 of AS 3850 provides mandatory and guidance provisions for the safe design, production and site handling of prefabricated concrete elements used in buildings. It complements AS 3850.1 and AS 3850.3 and addresses lifting and rigging design, casting practice, transport and erection procedures, temporary supports and the fixing/grouting of structural elements so they perform as intended once assembled on site.

General information

Scope

Applies to prefabricated concrete elements used in building construction, including but not limited to wall panels (tilt-up and precast), columns, beams, floor and façade elements. The Standard covers requirements for design and documentation, casting practices, selection and testing of lifting/anchorage systems, transport, cranage and erection procedures, temporary supports and bracing, and the fixing and grouting of elements once positioned. Annexes give information required on drawings, roles and responsibilities in planning and execution, the lifting design process and typical rigging configurations.

Key topics and requirements

• Design and documentation requirements for prefabricated elements (drawings, tolerances, lifting anchor specification and details).
• Casting practice and quality controls to ensure elements meet strength and dimensional requirements at time of handling.
• Lifting, rigging and anchorage design including working load limits, certification of proprietary inserts and rigging arrangements.
• Transport, cranage and erection procedures (route/tower/crane selection, restraint and stability during lifting and placement).
• Temporary supports and bracing — design, installation and removal sequencing to maintain element and structure stability.
• Fixing, grouting and making good — detailing of connections, tolerances and requirements for achieving structural continuity.
• Informative appendices: required information on drawings, stakeholder roles, lifting design process and typical rigging examples.

Typical use and users

Used by structural and design engineers, precast and tilt‑up manufacturers, site and erection contractors, lifting and rigging engineers, crane operators, building surveyors and certifiers, building clients and principal contractors involved in projects that incorporate prefabricated concrete elements. It is referenced in project specifications, shop drawings, lifting plans and erection procedures.

Related standards

Complements the AS 3850 series (AS 3850.1 and AS 3850.3). Commonly used alongside AS 3600 (Concrete structures), AS 1170 (Structural design actions), AS 1379 (Specification and manufacture of concrete) and other industry codes and supplier documentation for lifting anchors and rigging equipment.
