In the building industry today each projects is individually separated from another and almost no information is reused between them. By dividing a building into different modules it is possibly that for each module make the design process more effective and reuse experience from previously made projects. For a modulized product family configurators are usually used. This master thesis focuses on identifying a method to develop configurators and examine the applicability of the method for structural subsystems. A case study has been conducted to test the method and has been limited to only examine the subsystem non-piled concrete foundation. In order to design the main features of the method, interviews were held with people who have practical experience for creating configurators in the construction industry. The four steps that were identified for the method are Identification of variance, Calculation procedure, Parameterization and Configuration. The steps should be implemented in the described order, since each step is based on the results from the previous steps. In the first step, Identification of variance, variance of the object was investigated by collecting product information for the studied object from existing drawing documents. The information was compiled and analyzed to be able to use the most relevant to the following steps. The second step, Calculation procedure, was based on gathering information about the necessary controls and the equations which will fulfill the traditional design process of the studied object. The information was retrieved from the norms and standards as well as information from the previous step that contributed to the design was used. The third step, Parameterization, was the hardest step to go through because it involved reversing the traditional design process. Instead of calculating if the object meets all of the conditions, the parameterized equations are designed to meet all of the conditions. It was also important that the controls were calculated in a specific order to be able to calculate the sought parameters step by step. In the fourth step, Configuration, a model was created of the components that the object consisted of. The parameterized equations were connected to the model to be able to control the design of the model with the results from the equations. The design process was automated by controlling the design of the model with the parameterized equations. The conclusions are that the method can be used to configure structural subsystems and also further develop existing configurators. It is partly the decoupled interfaces between the modules that affect that the results of the case study can be generalized for all structural subsystems, and partly the product architecture of two study levels. The completed case study shows that the method needs to be completed by the analysis of the results. It is necessary to introduce practical engineering experience to specific occasions, since all the necessary knowledge is not found in norms and standards. How that integration can be done has not been considered, but the identification was made of when the knowledge was needed. It is important that there is an awareness about the objects product architecture in the use of the method, because it will contribute to determine the ability to create a configurator and how advanced the process will be.
