Abstract. Surpassing of the planned budget and delivery time is a common feature during the implementation of building investments in Poland. Only a small number of companies use effective methods of project monitoring during investment performance. One of the popular tools used to control projects with regard to cost and time is the earned value method (EVM). There is, however, no detailed guidance how to deploy the method to the specific characteristics and conditions during the execution of building investments. This fact has contributed to this paper, which presents the results of application and adaptation of the earned value method (EVM) and its further extensions in the control of building projects during their execution (with regard to cost and time), prediction of the final duration and costs, and presentation of the effects resulting from calculations. The analyses were performed in terms of the contractor for 5 selected completed and ongoing building projects in Poland.
