This article proposes the adoption of a numerical prognosis model to estimate the variable "execution time" for public projects in an objective way. The field work consisted of the application of statistical methods for analyzing data from projects that were bid and contracted by the Federal University of Pará (UFPA) between 2006 and 2009. Data analysis involved linear regression and transformed functions. After the stratification and initial treatment of the data, the evidence adopted for the construction of the final model was limited to 102 out of the 225 projects originally investigated, resulting in the following statistical parameters: correlation coefficient (R) of 0.899, coefficient of determination (R2) of 0.808, adjusted coefficient of determination (adjusted R2) of 0.796, and standard error (Se) of 0.41. These parameters show a strong linear correlation between the variables, indicating that 79.60% of the variability of the execution of a public project is jointly caused by variations in the gross floor area, the estimated cost, the operational technical capacity of the client organization; the operational capacity of the company; the type of service, and the season.

The construction of the Hydroelectric Plant of Belo Monte (HEP) on the Xingu River in Altamira in the state of Pará, in the Amazon, has been the subject of great controversy and debates on various social, institutional and media spaces due to the complexity the impacts that work brings to society, the environment, indigenous peoples, fisherfolk and riparians, resulting in several lawsuits, but also strikes and workers' claim wage improvements, work conditions and health. The study aims through a qualitative and descriptive approach first examine the box of disease among employed workers, and second, to characterize the forms of health care in the city of Altamira, exam notes that the failure of public policy to respond to demands and produce suitability the increase in migratory flows caused by mega project. During fieldwork in the period 09 to 24 July 2013, 25 workers from the construction sites of UHE were interviewed using Form with open and closed questions. The survey focused research sources in newspapers and public and private institutions about the issues related to working conditions and health of workers in the construction sites of the Belo Monte to enable an interpretative scheme that indicate could also propositions towards prevention in worker health.
