ISO 13315-5:2025

Overview

ISO 13315-5:2025 - Environmental management for concrete and concrete structures - Part 5: Execution of concrete structures - specifies principles and procedures for environmental management during the execution phase of concrete structures. It covers site-based activities including earthwork/foundation work, formwork, reinforcement work, concreting work and waste treatment. Additional works such as electric and utility installations are explicitly outside the scope. The standard integrates life‑cycle thinking and references ISO 14040/14044 for assessment methods.

Key technical topics and requirements

• Scope of execution activities: Environmental management applies to the entire execution process or to individual works (earthwork, formwork, reinforcement, concreting, waste treatment).
• Structured procedure: A stepwise procedure is mandated:
  1. Confirmation of client brief and design documents
  2. Setting environmental performance requirements
  3. Formulation of the construction plan
  4. Estimation
  5. Verification
  6. Execution of works
  7. Inspection
  8. Documentation
• Impact categories: Selection from categories such as global climate change, natural resource use, ozone depletion, land use/habitat alteration, eutrophication, acidification, air/water/soil pollution, radioactive pollution, waste generation impacts, and noise/vibration.
• Indicators and performance requirements: Set quantitative indicators for selected impact categories. Indicators can be absolute values, reduction amounts, or reduction rates relative to a defined reference execution activity. The standard references ISO 21929 and ISO 21931 for indicator guidance.
• Construction planning measures: Options include selecting low‑impact materials, low‑carbon energy sources, lower‑impact machinery, optimized execution methods, and appropriate on‑site control/disposal of discharges and wastes.
• Verification and documentation: Requires estimation and verification of expected vs attained environmental performance, inspection during execution, and formal documentation of outcomes.

Practical applications and users

ISO 13315-5 is intended for:

• Contractors and construction managers preparing environmentally optimized execution plans for concrete structures.
• Designers and clients who need to confirm environmental requirements in briefs and specifications.
• Environmental managers and sustainability consultants performing site LCA, setting indicators, and verifying reduction targets.
• Specifiers and procurement teams selecting materials, equipment, and energy sources aligned with environmental performance requirements. Practical uses include setting contractual environmental performance criteria, comparing target vs reference execution activities, and documenting compliance for green building programs or environmental labels.
