Adequação estrutural dos pilares de um edifício residencial em concreto armado na cidade de Rio Branco
(Universidade Federal do Pará, 2013-11-06) SANTOS, Mateus Silva dos; OLIVEIRA, Dênio Ramam Carvalho de; http://lattes.cnpq.br/1324105476558186
The recovery and strengthening of reinforced concrete structures are increasingly common in Brazil, mainly due to the aging of structures built in the 60s and 70s of the twentieth century, which are close to reaching their lifetime. Added to this, factors such as the use of concrete with low strength, execution failures, improper use and lack of maintenance. Due to these factors that society should endeavor to enhance and / or restore these buildings, thus avoiding demolition of the same and even avoid fatal acidentes. This paper presents a case study that aims to recover a building that is abandoned for nearly two decades in the city of Rio Branco, Acre State. Currently, there are various techniques for strengthening reinforced concrete structure. Such as reinforcement through reinforced concrete jacketing, supplemented or enhanced with added armor, enhanced with application of metal sheets and profiles, reinforcing pillars reinforced with carbon fiber (PRCF), among other. In this work, the method adopted for recovery was enhanced by reinforced concrete jacketing. And for a better understanding of the methodology adopted work also presents details of the enhanced configuration adopted, constructive detail and executive procedures of the method adopted. In addition, the wrappers showing the active and resistant efforts before and after the booster.

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.
