The European standard DIN EN ISO 29481-1 "Building information models - Information delivery manual - Part 1: Methodology and format" has been comprehensively reviewed to incorporate improved methods for the creation and technical implementation of information delivery manuals in a format that can be read by software programs. Existing information delivery manuals such as the IDM (Information Delivery Manual) remain valid despite these changes.
Building Information Modeling (BIM) provides a digital technology that describes and presents information for the planning, design, construction and operation of built assets. This modelling approach increasingly integrates all aspects of the built environment, including civil infrastructure, utilities and public space, which are collectively referred to as building processes. Through this information management, the various data sets used in the life cycle of the built environment are brought together in a common information environment, reducing or even eliminating the need for various types of paper documents. BIM refers to both the process and the product of this process, namely the Building models.
To get the full benefit, an IDM can be helpful. If the information needed to support the construction process or a use case is available in BIM and is of satisfactory quality, the actual process can be significantly improved. This part of ISO 29481 specifies the following:
-A methodology that links the business processes during the construction phase of a building with the required information specifications.
-A way to record and describe the information processes during the life cycle of a building.
ISO 29481-1 is intended to facilitate the Interoperability of software programs used in the various phases of the life cycle of construction works, including consulting, design, documentation, construction, operation, maintenance and demolition. In addition, the standard promotes the joint work of various actors involved in the construction process and creates a basis for making the exchange of information error-free, reliable, repeatable and of high quality.
