BS EN 17412-1:2020 pdf free.Building Information Modelling一Level of In formation Need.
BS EN 17412-1 This document specifies concepts and principles to establish a methodology for specifying level of information need and information deliveries in a consistent way when using building information modelling (BIM).This document specifies the characteristics of different levels used for defining the detail and extent of information required to be exchanged and delivered throughout the life cycle of built assets. It gives guidelines for principles required to specify information needs.The concepts and principles in this document can be applied for a general information exchange and whilst in progress, for a generally agreed way of information exchange between parties in a collaborative work process, as well as for an appointment with specified information delivery.The level of information need provides methods for describing information to be exchanged according to exchange information requirements. The exchange information requirements specify the wanted information exchange. The result of this process is an information delivery.This document is applicable to the whole life cycle of any built asset, including strategic planning, initial design, engineering, development, documentation and construction, day-to-day operation, maintenance, refurbishment, repair and end-of-life.When the level of information need is specified, the purposes for information delivery shall be considered.The purposes should be specified to clarify why the information is needed. The level of information need should be used for the purposes it has been required for.The level of information need does not specify the purposes. To achieve the same purpose, the geometrical information, alphanumerical information and documentation can vary for different objects.To perform an accessibility analysis, requirements such as the clear opening width of a door, its
location, the position and shape of the handle are needed. Other properties, such as the name of the manufacturer and the acquisition cost, are not relevant to fulfil the purpose. On the other hand, for cost analysis purpose, the acquisition cost of a door is needed, but the appearance of the handle is not relevant. For rendering purpose, the geometrical appearance of a door is relevant, while the name of the manufacturer and the acquisition cost are not.BS EN 17412-1 pdf download.
