Compressão tempo-custo paramétrica ótima de projetos de construção civil
(Universidade Federal do Pará, 2012-08-30) BENTES, Jayme; ICHIHARA, Jorge de Araújo; http://lattes.cnpq.br/5726366418302065
One of the issues of the Civil Construction Industry is around the planning phase of the the project, when is possible to verify the difficulty in completing the project in time, initially, thinking as the contractor. Therefore, the present study proposes the application of the linear programming method as a solution to the problem of the optimization of the factors time and costs from the Civil Construction projects. Initially it was done, by bibliographic mapping, also as the re-reading of some basic concepts, programming Technics with network and critical path. Afterword, it was discussed definitions of operational research and mathematical models of Linear Programming. It was proposed, therefore, a method aiming the solution of the issue of the time optimization and projects expenses of Civil Construction. To demonstrate the application of the proposed method, it was used as a scenario, a governmental construction project, that the goal was the compression of the project in 14 days, reaching a period of contract, a cost of compression the amount of R$ 95,040.15 (ninety five thousand forty dollars and fifteen cents), less than if there were an increase in penalty for delay. With this achieved our objective, compression project for the desired duration.

Construção fragmentada: uma análise gerencial dos processos construtivos do complexo de prédios do Instituto de Educação Matemática e Científica (IEMCI) da UFPA
(Universidade Federal do Pará, 2013-01-22) BORDALO, Rosa Helena Coutinho; LIMA, Adalberto da Cruz; http://lattes.cnpq.br/7803369097132222
In recent years the Federal University of Pará (UFPA), among other important precautions, has invested significantly in the restructuring and expansion of its campi, the construction of new buildings, expansion and renovation of the existing ones. As in most IFES, however, the UFPA has no structure or enough time for the responsible technical crew to manage and develop constructive project execution, monitor and supervise the construction works and maintenance. The objective of this study is to make a management analyze of the construction processes at the UFPA, on the basis of the complex of buildings of the Institute of Mathematics and Science Education (IEMCI), aiming the identification and minimization of the problems presented along its flow. To do so, through a case study of the administrative procedures and other documents related to the construction of the various modules that make up the Institute, with the data collection of all the performed works, and conducting interviews, based on the Campos's model (2011), to everyone involved in the process. After analyzing the results, the conclusion was that a lack of planning and effective management of constructive processes produced several problems, among them, incomplete and flawed projects, leading to fragmented construction. The construction executed through stages cost 35.19% more than if it was performed in one step and in its entirety. And as the term, this increase was even greater, reaching 283%. Concluding that the interveners caused by fragmentation, seriously influenced on the deadline and the final cost of the construction.
