The tremendous economic challenges especially due by the persistence of the financial crisis and the continuous decline of public investments in the last years have increased the financial risks faced by construction companies, which make them very vulnerable. The financial weakness manifested by the lack of liquidity leads to delays in the project implementation, in penalties for delay and lost opportunities, with direct effect on the health status of projects and organizations. Infrastructure construction projects are mainly base on FIDIC Conditions of Contract amended through special conditions by employer. The paper examine the effect of conditions of contract relating to the financial relationship between the employer and the contractor and the influence that they have on the financial management exercised by contractor, in order to provide them a practical tool for decision-making.
