(1) EN 1991 1 8 gives principles and rules to determine the values of wave and current actions on structures and civil engineering works in the coastal zone, i.e. works connected to, or in close vicinity to the shore.
NOTE 1 Provisions in EN 1991 1 8 are limited to hydrodynamic actions that can be directly quantified in terms of wave and/or current induced pressures and associated forces and moments on structures or structural parts.
NOTE 2 As opposed to offshore conditions, waves or currents in the coastal zone are generally affected by the presence of the seabed or shore.
NOTE 3 The coastal zone is typically defined as the area between the shoreline and the deep-water limit.
(2) EN 1991 1 8 describes the principles for defining the hydrodynamic conditions to be used for design, including sea water levels.
(3) EN 1991 1 8 addresses specifically actions from currents and waves on the following structure types:
— cylindrical structures;
— subsea pipelines;
— suspended decks;
— vertical face structures;
— permanently moored floating structures.
NOTE 1 Additional guidance can be needed for:
— moored structures in the coastal zone for renewable energy production or related to oil and gas production or processing;
— moored structures spanning areas with variable wave and current states (e.g. floating aquaculture farms or floating bridges).
NOTE 2 For hydraulic pressures caused by quasi-static water levels, and ground water, see EN 1997 (all parts).
(4) Actions addressed in EN 1991 1 8 do not cover:
— hydraulic resonance in sheltered areas or basins (phenomena also known as harbour resonance);
— translation waves, e.g. tsunamis;
— waves and currents induced by maritime operations, i.e. vessel wake, berthing and mooring;
— hydrodynamic actions induced by earthquakes;
— ice-induced pressures and forces;
— coastal structures where flood risk and/or erosion or sediment management is the dominant function.
1.2 Assumptions
(1) The assumptions given in EN 1990 apply to this document.
(2) In addition, it is assumed that actions from waves and currents on coastal structures are determined by personnel appropriately qualified and experienced in the following fields:
a) physical coastal environment including physics of waves and currents, statistical properties and propagation of such;
b) marine hydrodynamics, wave and current interaction with structures in general and wave and current actions on structures in the coastal zone including i) fixed structures, and ii) floating structures;
c) advanced methods including probabilistic methodology and physical model testing.

NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids.
NOTE 2 For limitations on rules for silos given in this document, see 1.3.
NOTE 3 For limitations on rules for tanks given in this document, see 1.4.
(2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them.
NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data.
(3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures.
NOTE FRP is the standard acronym for fibre reinforced polymer materials.
(4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project.
NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos.
NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks.
1.2 Assumptions
(1) The assumptions of EN 1990-1 apply.
(2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks.
1.3 Limitations on silos
1.3.1 Geometrical limitations
(1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document:
- the silo planform cross-section shapes are limited to those shown in Figure 1.1c.
NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7.
NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c;
- the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1):
hc/dc < 10 (1.1)
hb < 100 m (1.2)
dc < 60 m (1.3)
NOTE 3 See Figure 1.1 for hc, dc and hb.
- the structural transition lies in a single horizontal plane (see Figure 1.1a).
[Figure 1.1 - Silo forms showing dimensions and pressure notation]
(2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b = 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations.
(3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document.
(4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped.

The scope of this project is to provide guidelines for information exchange between BIM and GIS. As part of a series of proposed international standards for BIM-GIS information exchange, Part 02: Facilitating data exchange through metadata will aim to solve metadata issues to support bidirectional GIS/BIM information exchange and suggest technical requirements based on use case scenarios. Metadata give great opportunities to find, evaluate and manage relevant information for the bidirectional information exchange. To ensure the interoperability between GIS and BIM information models, it is critical for one domain experts to understand the metadata generated from the other domain and vice versa. The work will review existing methodologies and research with regard to bidirectional GIS/BIM information exchange, especially in terms of metadata and item registration. It will provide a use case scenario to give a certain context of bidirectional exchange of metadata. The use case will also provide the context within which the interaction that needs to be taken place between GIS and BIM model experts. With the use of the use case scenario, the process of properly generating metadata for each domain to ensure the bidirectional exchange can be identified. It will then list the technical requirements to support the process and provide a guideline to follow.

This document establishes the core principles and specifications for enabling structured and semantically consistent information exchange between BIM and GIS. It provides a comprehensive framework for understanding, planning, and implementing information exchanges that span both the BIM domain and the GIS domain.
This document provides a conceptual framework, built around eight perspectives on BIM-GIS information exchange: life cycle, process, product, data, exchange, actor, geospatial, and standards perspectives, how they shape, dictate, or constrain the structuring and execution of information exchanges, and the relationships between them and their application to specific use cases.
It also addresses the following key elements:
Requirements definition and hierarchy for BIM-GIS information exchanges
Services enabling exchange and integration, transformation, query and analysis, and visualization and communication
Functions supporting spatial registration and georeferencing, data harmonization, linking, analytical operations, and workflow management
Resources including data and information types, formats, and their characteristics
Repositories for centralized data management, translation and integration, and specialized storage

This document provides guidelines for the data exchange between BIM and GIS through metadata. This document explains the role that metadata plays in facilitating data exchange within the framework of the standards referenced in ISO/DIS 23143-1, Clause 6.3 (Metadata resources).
This document offers a perspective on leveraging metadata to ensure interoperability between BIM and GIS. It builds on the core principles established in ISO/DIS 23143-1 by presenting how metadata supports communication between the two domains, thereby facilitating seamless data exchange
This document defines a framework for facilitating data exchange between Building Information Modelling (BIM) and Geographic Information Systems (GIS) through metadata-driven interoperability. It specifies methods for identifying and cross-mapping metadata elements in the GIS Metadata Schema (ISO 19115-1:2014 [2]), and for deriving BIM-side metadata from IDM Data Schema (ISO 29481-3:2022 [1]) to support semantic alignment and structured transformation between the two domains. ISO 29481-3:2022 [1] is used as a source to derive BIM-side metadata candidates for cross-mapping and is not treated as a metadata schema.
The scope of this part includes:
1) Establishing metadata-based cross-mapping rules to support the semantic translation of information between BIM and GIS, including the use of BIM-side metadata candidates (derived from ISO 29481-3:2022 [1]) and GIS metadata elements (ISO 19115-1:2014 [2]);
2) Supporting bidirectional information requests and responses, where each domain (BIM or GIS) can serve as either information provider or consumer.

This document gives guidance on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents.
The methods can be applied to individual wood species and processed wood-based materials, including thermally and chemically modified, and water-repellent impregnated wood. Examples of wood-based materials are oriented strand boards (OSB), particle boards, fibre boards, laminated veneer lumber (LVL), and plywood. However, this document is not intended to give guidance on methods for determining and classifying the durability of wood products, coated wood, and wood polymer composites.
Preservative-treated wood is not within the scope of this document, since requirements for the effectiveness of wood preservatives and durability requirements of wood treated with preservatives are regulated in several other European standards. However, this does not apply to modified wood, which is why it is included in the scope of this document.
The wood-destroying agents considered in this document are:
— wood-decay fungi (basidiomycete and soft-rot fungi);
— beetles capable of attacking dry wood;
— termites;
— marine organisms capable of attacking wood in service.
Data on the biological durability of the heartwood of selected wood species considered of economic importance in European countries are presented in Annex A (informative), which also provides information relating to their geographical origin, density, sapwood width and treatability.
NOTE Treatability, durability to disfiguring fungi, permeability to water and performance in use of wood and wood-based materials are also important issues. However, because standardized methods aiming to assess and classify these factors do not exist and/or have not been extensively experienced yet, preliminary guidance is given in Annex B (informative) for the classification of wood treatability with aqueous wood preservatives, Annex C (informative) for the classification of the permeability to water, and Annex D (informative) for the durability to disfiguring fungi.

Method A - Method of determining the glass content of GBS by X-ray diffraction.
Method B - Method of determining the glass content of GBS by polarized optical microscopy.
The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass.
It is usually expressed as a percentage (wt%) of the total slag.
In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.
