Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents.

Introduction

Building Information Modelling (BIM) is a process for digital representation of the building. It starts from the very early stages of a project and covers all the phases of the building life cycle. The objective is to benefit from the digitalization of the information to replace the paper drawings and documentation that have been used in the building industry until now. This makes it possible for the same information to be available to all the actors in real time.

The main concept to describe the maturity of a project is called "level of information need" (see ISO 7817‑1). The concept of level of information need is introduced in ISO 19650‑1 and is used instead of the concept of level of development (LOD). The level of information need addresses the geometrical information of the object, the alphanumerical information and the documentation referred to it. Therefore, the level of information need has been split in three: the geometrical information, the alphanumerical information and documentation. In addition, the level of information need is based on pre-requisites: purpose, information delivery milestone, actor and object.

In principle, geometrical information, the alphanumerical information and documentation will develop simultaneously, but it can happen that there are big differences between the geometrical information, the alphanumerical information and documentation. For example, an object may have a symbol description on the geometrical information where all technical data and performance expected from the object can already be included in the alphanumerical information in a dedicated database, while a technical specification might be in a document. The fact that level of information need is split between geometrical information, the alphanumerical information and documentation helps to address the different expectations at each moment of the project, and this makes BIM even more efficient.

The information needed varies along the project, not always in a linear way: it might start very limited and schematical at the very early phase, to highly detailed once the building is under construction, and with less geometrical information during operation (with mainly the operating zones, without fabrication representations).

The quantity and quality of information depends on when information is required and the purposes it supports. At pre-design stage, the elements are usually not yet detailed, and the dimensions are not final. Presented objects can be symbolic, or any other generical representation. Any information at pre-design stage may further evolve while the project goes on. At schematic design stage, the objects have general dimensions that allow to reserve space for a particular function in the building. At detailed design stage, the representation will contain full geometrical dimensions of the objects, as well as alphanumerical information associated to it.

The BIM approach reduces the risk of misunderstandings or gaps in the geometry, on the specifications or whatever relevant information has been delivered.

1 Scope

This document defines minimum specific elements required for BIM process with new lifts. It does not define the BIM process itself. This document specifies a minimum set of information for lifts following the structure of ISO 7817‑1, for the purpose of building planning during pre-design stage, schematic design stage and detailed design stage of a building. It covers the geometrical information and the alphanumerical information.

NOTE The BIM processes are defined in ISO/TC 59/SC 13 standards.

This document does not cover requirements during other stages (information delivery milestones) and the documentation.

This document does not cover definition of actors, which are project specific.

The definitions are for a single lift. This document does not describe the structures required for multiple lifts in the same building.

This document describes the information of a lift and its interfaces to the building which are relevant for the planning of the building. The structural forces are out of the scope of this document.

This document is not applicable to lifts, which are installed before the date of its publication.
