The implementation of a construction project requires many workers from different fields and professions. Their common goal is to make sure that the object is built as fast as possible, with minimum costs, and with the highest level of quality. Participants in the project exchange information. Their work is based on an enormous quantity of information, which has to be available to all. Any information loss, duplication of information, or asymmetries of information may generate additional project costs. As a result of information management, money can be saved by shortening project duration or workers' working time or reducing implementation costs. Through information management, higher quality of products can also be achieved. In this master's thesis, we focus on information management in the construction phase. We presented communication in the field of construction, basic needs arising from a common data environment, regulations in this field, and solutions achieved to this day. We reviewed and analysed the current situation related to programs and applications used to manage data and common data environments. By examining advantages and disadvantages of such data environments, we conducted an analysis of their functionalities. Based on experience from previous projects we participated in, we presented characteristics of a communication environment required by workers involved in the construction phase. After analysing individual communication and data transfer activities in a traditional way, we compared them to shared environment communication. Based on these analyses, we assessed savings brought by such an environment. We determined that, by actively using a shared data environment in our work, we are able to achieve savings, which was also demonstrated in this master's thesis.
