Abstract

In the execution of public works, the failure of the contractual compliance time is more expensive for the Contracting Authority due to the onset of disputes, the failure to fruition on schedule, etc. Several studies carried out in recent years have found that the actual duration of the works is higher than contract in 90% of cases. In the executive project, not by knowing the actual characteristics of the contracting firm, for estimating the duration of the works, not well certain resources - based only on the labor incidence indicated in the price lists - are assumed. The paper proposes a methodological approach that allows the technician, in executive project phase, the estimation of aduration of the works so-called conventional, setting some parameters according to experimental observations and considering only deemed critical activities. Starting, in fact, from the comparison of the two methods commonly used (calculation of men-day and Circ. n. C/175 Cassa per il Mezzogiorno 02/03/1982), through processing of the parameters contained in them, an algorithm that can be a useful reference for determining the duration of the works has been achieved, even with limitations and by means of further studies.
