The idea of the project is presented by a set of different activities that are marked by time dimension (beginning, middle period and the end). This is the key difference that differentiates a project from other business activities. However, although the project has its end, project ideas and goals are something that remains after the implementation of various projects and represent the whole purpose of project implementation. There are several phases of the project life cycle. The project life cycle usually includes project launch, project planning, project execution, and project closure. Sometimes the phase of the project is mentioned - control or monitoring of project activities. The project manager is a key person in the project process. He is in charge of implementing the project plan, leading and managing the project, quantifying the necessary resources and controls and various support mechanisms. In this case the structured project parts are reviewed on the example of the company Kaldrma d.o.o. One of the most important implemented projects of Kaldrma d.o.o. is the implementation of the construction of the petrol station and business premises of this company based in Imotski. An overview of project activities showed that the project was successfully implemented, implemented within the set time frame and today meets the project objectives. In addition, the long-term and success of this project is reflected in the financial stability of Kaldrma d.o.o. One of the observed deficiency in the example of Kaldrma d.o.o. represents a financing process that was one-sided, the project was financed exclusively by private equity while future investments will certainly focus on the available external sources of financing, as a way of closing the financial construction of the project. This is one of the lessons learned during the implementation of this project, which will be implemented by the project team during future investment cycle, which are currently in the phase of development of project idea.
