Full title and description

St ISO 22966-2009 — Execution of concrete structures. This International Standard gives common requirements for the execution (on‑site works and erection of prefabricated elements) of concrete structures, and defines the content of the execution specification that contractors and designers should use when planning and carrying out concrete works.

Abstract

ISO 22966:2009 establishes common requirements covering execution of concrete structures (in‑situ and using prefabricated concrete elements). It specifies what should be included in the execution specification, addresses permanent and temporary works, and clarifies which execution aspects are within its scope and which are excluded (for example, production and conformity of concrete and specific product standards for precast elements).

Scope

ISO 22966:2009 applies to the execution of concrete structures both for in‑situ works and where prefabricated concrete elements are erected on site. It is intended to ensure that the execution specification contains all requirements relevant to the particular structure. The standard is applicable to permanent and temporary concrete structures. It explicitly does not cover specification, production and conformity of concrete as a product, precast production covered by product standards, safety and health aspects (third‑party safety requirements), nor contractual allocation of responsibilities.

Key topics and requirements

• Contents and preparation of the execution specification (tasks, tolerances, checks and acceptance criteria).
• Reinforcement and prestressing — placing, fixing, protection, and verification.
• Concrete placing, compaction, curing, and protection of placed concrete.
• Requirements for jointing, tolerances, surface finishes and repairs.
• Inspection, testing and verification procedures on site, and documentation of non‑conformities.
• Requirements when using special materials or techniques (lightweight aggregates, fibres, special admixtures) and indications for when additional execution requirements are needed.
• Coordination between site works and precast element erection (interfaces and responsibilities).

These topics reflect the principal areas of guidance and mandatory requirements set out in the standard for consistent execution practice.

Typical use and users

Typical users include structural designers and specifiers preparing execution specifications and drawings; main and specialist contractors and site managers responsible for formwork, reinforcement, prestressing and concreting operations; quality managers and site inspectors implementing quality control and acceptance; precast producers coordinating site erection; and clients/project owners who require standardized execution criteria. Adoption improves coordination, reduces execution risk and provides consistent technical requirements for complex concrete works.

Related standards

Commonly referenced and related documents include standards for concrete specification and constituent materials (for example ISO 22965 series), standards on reliability of structures (ISO 2394), reinforcement and prestressing test and production standards (ISO 6934, ISO 6935 series, ISO 15630, ISO 17660), and regional execution standards such as EN 13670. The standard has also been adopted or referenced by regional/gulf catalogs (GSO adoption records).

FAQ

Q: What is this standard?

A: ISO 22966:2009 is an International Standard titled "Execution of concrete structures" that defines common requirements and the content of execution specifications for concrete works, covering both in‑situ construction and erection of prefabricated elements.

Q: What does it cover?

A: It covers preparation of execution specifications, requirements for formwork, reinforcement and prestressing, concreting, curing, tolerances, joints, inspection and testing on site, documentation of non‑conformities, and coordination between site and precast activities. It excludes product specification/production of concrete, precast production governed by product standards, and health/safety or contractual allocation issues.

Q: Who typically uses it?

A: Structural designers, specifiers, contractors and site managers, quality managers and inspectors, precast producers and project owners use the standard to create and verify execution specifications and on‑site procedures.

Q: Is it current or superseded?

A: The document was published in November 2009 (Edition 1) and is recorded as a published/active ISO standard. The ISO catalogue shows the standard's lifecycle and periodic reviews; users should consult the ISO catalogue or their national standards body for the absolute latest status or any revisions after 2009.

Q: Is it part of a series?

A: It is related to other ISO publications dealing with concrete and reinforcement (for example the ISO 22965 series on concrete specification and other ISO standards referenced for reinforcement and testing). It is intended to be used alongside those product and testing standards rather than as a replacement.

Q: What are the key keywords?

A: Concrete execution, execution specification, formwork, reinforcement, prestressing, placing, curing, tolerances, inspection, precast erection.
