Resumo

Conducted surveys indicate delays in projects that impact clients, allowing lawsuits over Construction Company and overhead costs of the project, enabling the economic impracticability of it. Through the above are needed more effective tools for term control of the project. Therefore, the work objective is to implement and evaluate the method of the critical chain in the planning and physical control of the project by calculating the project buffer using two different techniques: Trapezoidal Fuzzy Number (TrFN) and Fifty percent Method. Therefore, there was a case study of a mixed use building in Goiânia and monitoring of structural services of a joint, which are present in the project critical chain. Thus, to evaluate and compare the resulting buffer, calculated duration and really happened duration, it is concluded that the TrFN method comes closest to real time as it consults experts; and more integrates the team, increasing the applicability of planning, because the project performers are involved in preparing it. Now the fifty percent method is easier to be calculated with faster definition of the buffer and planning. Based on this calculus, the main contribution of this work is to compare the results of each technique in: application agility, application accuracy, applicability during construction.
