Overview

The draft international standard prEN ISO 20770-3:2025 addresses safety requirements specific to foundation equipment used in drilling and foundation construction. As part 3 of the ISO 20770 series, this document complements the general requirements outlined in ISO 20770-1 by focusing on foundation equipment-machines that install or extract foundation elements through techniques such as piling, vibrating, pushing, and drilling.

This standard is relevant for manufacturers, operators, and safety professionals involved in foundation equipment design, operation, and compliance. It covers significant hazards throughout the machinery’s lifecycle under reasonably foreseeable conditions of use and misuse.

Key Topics

• Scope and Equipment Types
  The document applies to foundation equipment fitted to carrier machines, including impact piling rigs, rotary piling rigs, and vibration piling rigs. Foundation equipment typically handles longitudinal foundation elements (e.g., concrete piles, steel beams, tubes), injection elements, casings for cast in situ, soil improvement, and vertical drainage applications.

• Safety Requirements
  Safety rules address machine stability, operator safety, moving parts, noise limits, and auxiliary equipment. Foundation rigs must comply both with ISO 20770-1 general safety requirements and specific provisions for foundation machines outlined in this part.

• Carrier Machine Compatibility
  Carrier machines such as cranes, cable excavators, or hydraulic excavators must meet relevant standards like EN 13000, EN 474-12, or EN 474-5, respectively, and be fully compatible in strength, stability, and hydraulic pressure with the foundation equipment.

• Stability and Risk Reduction
  The standard specifies conditions to ensure rigid body stability, including detailed testing of stability angles and ground support considerations (use of timber or steel plates), to avoid tipping or unintended displacements during operation.

• Noise Control
  Annex A provides a noise test code to assess noise levels produced by foundation equipment, supporting operators' health and compliance with regulatory limits.

• User Information and Documentation
  Clear operator manuals and safety instructions are emphasized to ensure proper use and maintenance of drilling and foundation machines.

Applications

• Foundation Construction and Earthworks
  This standard is crucial for enhancing safety in foundation construction projects, including piling, soil improvement, and vertical drainage operations, where foundation rigs are extensively used.

• Manufacturing and Design
  Manufacturers designing foundation equipment can use this standard to integrate safety measures that meet international regulatory and technical requirements.

• Occupational Safety
  Site safety managers and equipment operators benefit by adopting the standard guidelines to reduce hazards and manage risks during foundation machine operation.

• Compliance and Certification
  National standards bodies and regulatory agencies may reference prEN ISO 20770-3 during machine certification or workplace inspections, ensuring machines meet safety requirements for industrial use.

Related Standards

• ISO 20770-1 – Drilling and foundation equipment - Safety - Part 1: Common requirements, establishing general safety principles.
• ISO 20770-2 – Safety guidelines for mobile drill rigs with rotary head torque less than 35 kNm and multidirectional drilling capability.
• EN 13000 – Mobile crane safety requirements, relevant when cranes serve as carrier machines.
• EN 474-5 / EN 474-12 – Safety requirements for hydraulic and cable excavators used as carrier machines.
• ISO 12100 – General principles for design and risk assessment of machinery safety.

This collaborative framework between ISO and CEN ensures that foundation equipment safety is harmonized internationally, reflecting best practices in earth-moving machinery to protect workers and optimize operational reliability.

By implementing prEN ISO 20770-3:2025, stakeholders in drilling and foundation industries can enhance machine safety, improve operational performance, and meet evolving regulatory challenges globally.

The requirements of this part are complementary to the common requirements formulated in
ISO 20770-1:____.
This document does not repeat the requirements from ISO 20770-1:____ but adds or replaces the requirements
for application for foundation equipment.
In this document the general term “foundation equipment” covers several different types of machines used
for installation and/or extracting by drilling (machines with a rotary torque greater than 35 kNm), driving,
piling, vibrating, pushing, pulling or a combination of techniques, or any other way, of:
— longitudinal foundation elements, such as concrete piles, steel beams, tubes and sheet piles;
— injection elements as tubes and hoses;
— casings for cast in situ;
and used for:
— soil improvement by vibrating and soil mixing techniques;
— vertical drainage.
NOTE Some foundation equipment may have an additional rotary head with a torque less than 35 kNm for pre-
drilling applications; this equipment is covered by this standard.
Machines with one or more of the following characteristics are not covered by this standard, but are covered
by ISO 20770-2:____, including:
— machines that have a main rotary head torque of less than 35 kNm;
— machines that have multi-directional drilling capability;
— machines require additional measures during the installation/extraction process (for example, adding
or removing such as rods, digging tools, drilling tools).
