The integrated building process Information structures Facilitate for an uncomplicated and efficiant transfer of information between actors and processes and phases during the building process and through the whole life cycle of the building or the civil engineering work Kjell Ivar Bakkmoen, Sector manager Norwegian council for building standardization (NBR) Friday, 30 November 2018Friday, 30 November 2018

From classification tables to object/class/reference libraries Started as a review of the existing classification tables. Starting point: Need for structuring of information in the facility management phase - life cycle thinking Need for reuse of information from the construction phase to the management phase Parallell with participation in ISO, ICIS, IAI etc. Friday, 30 November 2018Friday, 30 November 2018

From classification tables to object/class/reference libraries We need a computer sensible library of all built objects We need a framework for object oriented information where all those information elements are referenced to each other - integrated A development towards an electronic model which will contain all information from “bubble” to grave.
