Product model based data can be utilised and exchanged in various ways in and between different sectors of design, construction site management, and product industry. The product models of the different parties in a construction project can be integrated into a shared model which is augmented with data as the project progresses. In designing, both common product libraries and company-specific product libraries are used, enabling the transfer of product data from design to manufacturing. Creating guidelines for architectural, structural and HVAC design is necessary in order to make sure that data is stored in a concise way and that each designer can make use of the other designers’plans. In addition to design guidelines, another important prerequisite for this is IFC, a data transmission standard that allows information to be trustworthily stored and transferred between different software. Product model based construction process has been tested in several pilot projects where the results have been promising. Developing common principles and operating methods further will speed up and streamline product modelling in the building construction industry. As a whole, a product model-based process will improve companies’customer service, productivity, and construction quality.  \nKeywords: product model, data transfer, product component libraries, IFC data transmission standard  \n1. Introduction  \nDuring years 2003 and 2004, the Finnish construction industry has developed design, construction and maintenance in the building construction process based on product modelling. The development has taken place within the framework of a technology project called Pro IT –  \nProduct Model Data in the Construction Process, in which businesses, research organizations, governmental organizations as well as interest organizations have participated. More information on this technology project can be found in a recent article [1].  \nA product model means a description of the building in such a way that, in addition to the geometrical 3-D visualisation, the model contains data defining the building and its components. The data may apply for example to the finishing structures in spaces, the characteristics of the materials, fire-resistance, colours, environmental impacts or sound insulation.  \nA product model is composed of product components, which can be modelled either on a caseby-case basis or by using ready-made product component descriptions in a product library. A product library is a collection of product components in an electronic form. The libraries contain the components commonly used in design, such as walls, doors and windows. It is also possible to make libraries of other product components, such as furniture and interior design accessories.  \nIn the Pro IT project, a standardised method is developed for the design of a product model in the stages of architectural, structural and HVAC design. The starting point in the different design stages is the model created by an architect. The data exchange between the parties is developed on the basis of the international Industry Foundation Classes standard (henceforth referred to by the abbreviation IFC [2]) .","cbCailH308bVL3Uf","https://ap.wps.com/l/cbCailH308bVL3Uf","pdf",1306359,12,"English","# 1.
