ISO 22040-2:2024

Overview

ISO 22040-2:2024 - Life cycle management of concrete structures - Part 2: Structural planning and design stage provides a practical framework for managing concrete structures during the planning and structural design phases. It builds on the general principles of the ISO 22040 series and applies to both newly constructed and existing concrete structures whose life cycles are being restarted. The standard defines how to set performance requirements, develop a basic Life Cycle Management (LCM) scenario, and transfer critical information from planning to execution and later stages.

Key topics

• Performance requirements and structural planning
  • Establishing the functions a structure must retain through its design service life.
  • Defining performance requirements in line with ISO 2394 and ISO 19338.
• Basic LCM scenario
  • Formulation of a scenario to ensure required performance over the design service life, including inspection and intervention triggers.
• Determination of structural concept
  • Selection of structure type, materials and main dimensions to meet performance, robustness and redundancy needs.
• Management items at the structural design stage
  • Design actions and verification procedures.
  • Assumptions and methods in structural analysis.
  • Material properties and their implications for durability.
  • Performance verification methods and limit states for management.
  • Assessment of sustainability indicators (economic, environmental, social).
  • Maintenance programme planning and handover content for execution and use stages.
  • End-of-life management including demolition planning and post-life activities.
• Information flow and feedback
  • Requirements for feeding design-stage information back to planning and transferring it to execution and maintenance teams.

Applications and users

ISO 22040-2:2024 is intended for organizations and professionals involved in the lifecycle of concrete structures, including:

• Structural engineers and designers
• Asset managers and infrastructure owners
• Contractors and construction quality managers
• Maintenance planners and facility managers
• Regulators and standards bodies

Practical uses include drafting performance-based design briefs, creating design-stage LCM scenarios, specifying inspection and maintenance programs, assessing sustainability indicators at design time, and improving documentation handover to construction and operation teams.

Related standards

• ISO 22040 (series) - Life cycle management framework
• ISO 2394 - General principles on reliability for structures
• ISO 16204 - Durability - Service life design of concrete structures
• ISO 19338 - Performance and assessment requirements for concrete design standards

Adopting ISO 22040-2:2024 helps improve durability, sustainability, risk management and lifecycle cost control by ensuring consistent transfer of design intent and management actions across the structure’s life cycle.
