This document specifies the measurement of forces by means of load cells carried out for geotechnical monitoring. For measuring forces by means of strain or displacement gauges, see ISO 18674-7.
General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674-1:2015.
This document is applicable to:
— performance monitoring of geotechnical structures such as anchors, end-anchored rock bolts, tiebacks, piles, struts, props and steel linings;
— checking geotechnical designs and adjustment of construction in connection with the Observational Design procedure;
— evaluating stability during or after construction.
Not subject of this document are devices where the load is purposely applied to geotechnical structures in the wake of geotechnical field tests such as calibrated hydraulic jacks for pull-out tests of anchors or load tests of piles.
NOTE This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of load cells as part of the geotechnical
investigation and testing in accordance with References [1] and [2].

This document specifies the requirements and gives recommendations for the design, sizing, installation, identification, commissioning and maintenance of rainwater harvesting systems for the use of rainwater on-site as non-potable water. This document also specifies the minimum requirements for these systems.
Excluded from the scope of this document are:
• the use as drinking water and for food preparation;
• the use for personal hygiene purposes;
• attenuation;
• infiltration.
NOTE Conformity with the document does not exempt from compliance with the obligations arising from local or national regulations.

This document specifies a method of testing the resistance of the upper assembly of inspection chambers and manhole components against surface and traffic loading.
It is not applicable to requirements for testing the cover and frame. Those requirements are specified in EN 124-1 or other standards, depending on the material.
NOTE Upper assembly components normally include shafts or risers, cones, telescopic adapters and near surface components.

(1) This document provides general rules for the design and verification of geotechnical structures.
(2) This document is applicable for the design and verification of geotechnical structures outside the scope of prEN 1997-3:2022.
NOTE In this case, additional or amended provisions can be necessary.
1.2 Assumptions
(1) In addition to the assumptions given in prEN 1990:2021, the provisions of prEN 1997:2022 (all parts) assume that:
— ground investigations are planned by personnel or enterprises knowledgeable about potential ground and groundwater conditions;
— ground investigations are executed by personnel having appropriate skill and experience;
— evaluation of test results and derivation of ground properties from ground investigation are carried out by personnel with appropriate geotechnical experience and qualifications;
— data required for design are collected, recorded, and interpreted by appropriately qualified and experienced personnel;
— geotechnical structures are designed and verified by personnel with appropriate qualifications and experience in geotechnical design;
— adequate continuity and communication exist between the personnel involved in data-collection, design, verification and execution.
(2) This document is intended to be used in conjunction with prEN 1990:2021, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works.
(3) This document is intended to be used in conjunction with prEN 1997-2, which gives provisions rules for determining ground properties from ground investigations.
(4) This document is intended to be used in conjunction with prEN 1997-3, which gives specific rules for the design and verification of certain types of geotechnical structures.
(5) This document is intended to be used in conjunction with the other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.
