Such a methodology will accurately define requirements for BIM implementation for different phases of the project. It will also evaluate companies' fulfilment of these requirements from previous projects or based on the presented technologies of the company. The evaluation methodology will find its application both in the state administration and in the private sector of Czech civil engineering industry. In the current market, there is a need to quantify the level of implementation of work processes and outputs of the BIM methodology.
