Today’s increasing complexity, rising interconnectivity and larger systems in engineering require new approaches and methods for effective engineering. This is also the case for the technological installation in infrastructure sector (TII), which designs technical systems for infrastructural civil structures. To assist in engineering, Model Based System Engineering (MBSE) can be implemented that provides more control and linkage by means of modelling. The implementation process for MBSE is limited described in literature, especially for the TII sector. Desk research helped to understand and characterize the challenges of the TII sector. By means of in-depth interviews with Siemens Mobility engineers next, requirements were developed. Based on those requirements a framework for implementation of MBSE was constructed that consists of eight building blocks. An implementation process was constructed that puts the framework blocks in order and adds more information for implementing MBSE. The main component, the actual modelling, is split up into technical and process modelling. The technical modelling is fed by the choices and interactions of the process modelling. In the implementation process described which framework blocks are important at what moment, as well as update characteristics of the eventually MBSE environment. In the end, the MBSE methodology and the designed process with framework blocks seem promising for maintaining control of future engineering projects. It provides structure to for setting up the new engineering methodology for the TII in special.
