Completing 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.

The water supply is of paramount importance not only for human survival, but also for the development of economic activities and institutional, that is, to organic life / biotic and social life. Regarding the availability of this feature Brazil is a country with huge potential reserves to meet this end. The City University Professor José da Silveira Netto, the UFPA campus, currently produces its water, with funding through an underground aquifer, and in small quantities, also purchased from Local Dealership. However, in relation to production at the Federal University of Pará there is no knowledge about the maintenance costs of the production line, the hand labor involved, etc.. The lack of such knowledge does not allow the manager to act strategically with respect to this situation. This work aims to raise the direct and indirect costs of production of 1m³ of water treated at the City University Professor José da Silveira Netto, comparing it with the amounts charged by the Concessionaire site in order to show the manager what the most advantageous to the Administration with relation to the matter being addressed. Furthermore, future scenarios have been created in order that the activity is dynamic and growing university, beyond what was incorporated as conditions of energy cost and value of grants for water use, not yet integrated into the current cost of production. The results clearly demonstrate that the option of producing drinking water is the most economically advantageous for the institution, in any proposed scenario. Noting that the cost per m³ of produced water ranges from R$ 0,31 to R$ 0,45, while the purchase through the Local Dealership, around R$ 4,30 / m³ for the year 2011, only show viable if that price is a maximum of R$ 0,50 / m³. With this information and analyzes adequately presented clearly and technically considered, this work may be used as a management tool that will permit the public better or more adequate system of water supply in the City University Professor José da Silveira Netto.

One of the main barriers to expansion of sewage system in the country is the high cost of implementation of sewage disposal system, as being directly related to depth. Considering this problem, this paper presents two different studies tracings collection network type absolute tab for the city of Santa Cruz Arari - Marajó - Pará, in order to find the smallest depth and consequently the best cost. First, we designed two stroke sewage disposal system in the area with the highest population concentration is scaled according to existing technical standards. From the quantitative surveys of each stroke, there were budget spreadsheets with the possibility to compare among themselves the best network cost. Although there was little difference in length between the two paths, the item is weighed more than the depth of the network along the stretch of arrival of Sewage Pumping Station, for example, the depth was 4.90m and 4.77 m for the Path 1 and Path to 2, respectively. Soon we had the best total cost was Trace 2, with a total value of R$ 908,329.11 versus R$ 1,021,818.11 in Trace 1, representing a savings of R$ 113,579.00 to the same location. According to the results obtained, it was possible to evaluate the study tracing sewage disposal system becomes important for any location, as in this case study, where the city presents great difficulties of access and reduced costs for system implementation sewage.

The present research aimed to identify the main internal factors (costs, income, techno-economic feasibility and technologic innovation use) which affect the beef cattle activity competitiveness in a complete cycle production system in the state of Rio Grande do Sul. The data was collected during the year of 2008 based on monthly meetings between the months of January and December. Later the data was analyzed in eletronic spreadsheets. The costs were subdivided in disbursed, operating and total costs and the income in category and total. Among the evaluated costs, the land opportunity cost, labor force and animal supplementation with values of 19.9%, 18.3%, 13.6% respectively, can be pointed out in relation to total cost. The main financial and technical indicators commonly used in production systems analysis were calculated. The economic margins (gross, operating and net), as well as the profitability over the net worth were positive which show economic feasibility in the activity. At the same time, technical indicators as the output rate and the productivity/ha showed satisfactory values. Thus it can be concluded that the evaluated internal factors were very competitive for the studied system.

The wish and need of possess a fix dwelling are recurrent on Brazilian families. That require a planning with sacrifices for the family's, the same that should be seriously impacted by the recurring delays on delivery of housing units. The objective is measure monetarily the prejudice or damages adopting opportunity cost to value measure. Two parameters were considered, divided into 3 factors: The first parameter consists of two factors: 1) a physical disease due to the sum of frustrations(psychological disease) named effectiveness cost, 2)The living cost on overtime of property delivery contract to the client wich in theory will have to support two residencies. The second parameter correspond to legal costs that covers the cost of court proceedings and attorney fee cost. Three scenarios were built. : 1°) there is no psychological harm, or will not be considered, there being no cost effectiveness, 2°) damage restricted to one family member and 3 °) psychological damage throughout all the family. In a case study involving a single major construction company, conducted in another well-established research, found that the delay is on average 55.4 months. Being science fragmented in several areas of knowledge, which often do not interact with each other, multidisciplinarity was essential to achieve the proposed objective. It can be concluded that the opportunity cost ranges from R $ 76,371.69 to R $ 383,661.37 in absolute values, ranging from 16.30% to 70.16% of the apartments market value, depending on the scenario.
