Abstract [en]

Product models have long been theoretical models within international research communities, but are now starting to be adapted in the construction industry. Product models are data models that can contain both product and process data, such as geometry and planning data. Their current use in construction is mainly limited to 3D graphics, but product models have many more than three dimensions. In this research project we developed and applied different dimensions of product models beyond their common, but limited, use in 3D. Development and implementation efforts in the project are mainly driven by the interests from a ready-mixed concrete supplier. Product modelling systems imply an object oriented approach to cast in place concrete construction, which is not object oriented as a result of the nature of the product. Product models that are used in the design process differ from models that are used for production simulations. These, and other conditions, pose a number of challenges. However, product models offer also a number of opportunities to cast in place concrete construction. Products and processes can be simulated virtually for example, thereby facilitating the decision-making process regarding the application of new or existing technologies that can improve the construction process. Product models can also be used to link or integrate product data, such as material specifications, casting sequences, etc. Based on these, mainly theoretically identified, possibilities and constraints, a number of dimensions of product models are developed and applied in practice to different case study projects. The following model dimensions are explored in the project:Traditional 2D drawings and documents are partly generated from 3D models and hyperlinked to these models. Various types of 3D models from different disciplines are created by using file-based data transfers and a collaborative client-server environment. Multiple production plannings are linked to 3D models resulting in 4D models. 5D cost estimation is developed by linking different 3D models to cost estimation hierarchies. Model use and configuration of material parameters by a ready-mixed concrete supplier provides an additional dimension to the use of product models.The different dimensions illustrate on the one hand the support for new and existing products and processes for cast in place concrete construction and show on the other hand the potential of product model use beyond 3D graphics. Advantages and possibilities can be identified for the ready- mixed concrete supplier in the different model dimensions and we believe that other actors in construction can do the same. When actors have identified benefits of product modelling for their own business process they might be more willing to participate in shared product model use in search of benefits for the project team as a whole.
