Item Acesso aberto (Open Access) Análise das causas de aditivos de custo e de prazo em obras públicas de instituições federais de ensino(Universidade Federal do Pará, 2019-03-19) ALVARENGA, Felipe Campos; MAUÉS, Luiz Maurício Furtado; http://lattes.cnpq.br/7497951647889934Completing works within the cost and schedule stipulated in the planning phase is a major problem faced by managers in the construction industry. With this, several studies have been carried out around the world to identify the main reasons that lead to noncompliance with the works at the time and cost initially established. The present study aims to analyze the contractual additions made in public works of the Federal Institutions of Education (IFEs) and the main reasons that led to their conclusion. To achieve this goal, statistical tools were used to compare the cost and time changes between the country regions. The data of this work includes public construction projects divided in all the 5 regions of the Country, filtered from the database of the Ministry of Education. A diagnosis was made showing the percentage of additives among the regions and the main justifications of the same ones indicated in a sampling in this database. Statistical techniques such as the Kruskall-Wallis Analysis of Variance and the Mann-Whitney U-Test were used for data analysis and inference. As results, the differences in the distribution of time and cost additives were statistically significant among the regions, with the South and Central-West regions presenting the greatest differences and the North, Northeast and Southeast regions with a statistically similar behavior among them. Of the 2178 projects collected, 69.05% had additives of term and 61.89% of cost. The main factors that affect time and cost of the projects were the inclusions and / or modifications of design and the additions of services. The ways to reduce the incidence of overruns point to the use of Building Information Modeling (BIM) technology, lean construction and greater experience in the management of works.Item Acesso aberto (Open Access) Diagnóstico de reutilização e reciclagem de resíduos sólidos de construção civil pelas cooperativas de reciclagem no município de Belém-PA(Universidade Federal do Pará, 2019-07-05) ALMEIDA, Ana Victoria da Costa; MAUÉS, Luiz Maurício Furtado; http://lattes.cnpq.br/7497951647889934The Civil Construction sector is one of the most important segments of the world industry, being also the one that consumes the most natural resources, and therefore generates a large amount of solid waste. Construction Waste (RCC) is considered inert, but can cause problems when not properly disposed of. When we talk about RCC, we have CONAMA Resolution 307 stating that all municipalities must give RCC’s an environmentally sound destination in order to effectively reduce the environmental impacts generated by this type of waste. Within this context the present study made a diagnosis of the main practices involving reuse and recycling of RCC’s by recycling cooperatives in the city of Belém do Pará. To this end, an RSL was performed that assisted in the development of tools for the application of this research, and also helped in the conduction of studies that deal with the theme. With RSL it was possible to conclude that no study unites RCC’s and recycling cooperatives as a way of mitigation. Along with the cooperatives a Survey was applied and then a Likert scale through which it was found that the 4 cooperatives are already handling RCC’s and that it is no longer intense due to the lack of communication channel between the RCC generators and the cooperatives. Therefore, it is concluded that cooperatives are important allies for better management and destination of RCC’s and it is interesting to explore their potential, increasingly mitigating environmental problems related to the lack of RCC management by the municipality in question and thus give a more appropriate destination with help and social contribution for the cooperatives and the population of the municipality in questionItem Acesso aberto (Open Access) Etiquetagem PBE Edifica em edificação pública com auxílio da tecnologia BIM(Universidade Federal do Pará, 2019-10-30) ROSA, Rafael Cuimar Corrêa; MAUÉS, Luiz Maurício Furtado; http://lattes.cnpq.br/7497951647889934Building in a sustainable manner has been a great challenge for construction sector professionals. Labels are one of the tools available to make buildings more efficient in several aspects. Currently, public buildings above 500m2 of constructed area are required to plan and built with energy efficiency level A according to the Brazilian Program for Energy Efficiency - PROCEL, and for this reason, the knowledge of professionals in the area about the parameters of energy efficiency is essential. Thus, the Building Information Modeling technology, BIM, was used to generate the modeling of a public building located at the Federal University of Pará, which received adjustments in the model in order to make it more efficient. The Webprescritivo tool was used to evaluate the current situation and the changes applied in the building, by the prescriptive method, information was entered into the tool and it calculated the efficiency. As a result, it was found that the adjustments made in the model, allowed the building optimization, increasing from C to A its level of energy efficiency. Also, it was found that the use of BIM technology was able to assist in the assessment of the PBE Edifica label through the rapid process of component changes and generation of accurate tables with building data, but further studies and improvements are still needed for better interaction between the tools covered in this research.
