BIM technology and changes in traditional design process, reliability of data from related registers

Abstract

With the new technology of creating building design, many changes of traditional processes have to be set in order to reach project documentation and project design itself in higher quality level. As a traditional project documentation is changing in “digital twin” of building work, the way of building work design changes too. Building design and project documentation do not serve only for the building construction, maintenance and operation. Project documentation is the output, also the input – both at the same time - in connection with further building legislation, landscape planning, etc. BIM model, nowadays the highest quality of project documentation, should communicate with many related registers. Important basic information is as an input for the project design, afterwards information from the project design should be reflected as an output for the enlisting in related registers. Due to the absence of efficient digitization of the construction industry, the relevancy, correctness and reliability of information in the related registers is not very high in the Czech Republic, at this time. Digitization of construction industry and implementation of BIM technology promises many benefits. The magnitude of these benefits depends on how the data exchange is modified in the construction process during the whole building lifecycle. This paper reveals possibilities of basic principles of the new way of design using BIM technology, connections of BIM model data and related registers and their data exchange in the environment of Czech Republic´s legislation. The more correctly processed the model of the building work, the better and more reliable information for future designs.
