Abstract:-- Civil Engineering is an essential activity for the development of a country economy. It is also responsible for an enormous consume of raw materials and the production of urban solid waste. The purpose of this paper is to propose an alternative destination to recycling the waste produced during the construction of residential buildings, thought the process of crushing the material produced inside the job site. This process simplifies the logistics and reduces the costs related to the management of the waste, once all the produced materials will be used at the construction. To do so, it was analyzed a residential building construction and proposed two different equipments to crush the material. For the decision, it was chosen parameters, which consider technical aspects of operation (area needed, workers involved and requirements of the construction). Two economics models also analyzed the investment. As a conclusion, the process of recycling the waste from civil constructions is very important, as it associates ambient and economic aspects. The analyzed equipments are appropriate to constructions that has produces a great amount of waste, or which the developer has the interest in applying the process at others constructions. It will bring economic benefits and reduce the final cost of the edification.
Keywords: Civil engineering, construction waste, job site, recycling.

Abstract:-- Highway related accidents are considered one of the most serious problems in the modern world. According to the World Health Organization (WHO), more than 1.2 million people die each year in motor vehicle accidents. Jordan, as one of the developing countries, has high level of traffic accidents. In Jordan, traffic accidents have caused more than 4500 fatalities between the years 2007-2012. The main objective of this study is: to analyze fatal traffic accidents in the capital of Jordan, Amman in order to propose effective countermeasures to reduce the frequency and severity of traffic accidents in Jordan. Fatal accidents data for six years period (2007-2012) was collected from the Central Traffic Department in Amman and from the Jordan Traffic Institute for selected areas inside the capital Amman. The data was analyzed based on accident type, accident time (hour, day and month), victim characteristics (age, gender, location), weather conditions, road surface conditions, light conditions, vehicle type, speed limit, driver fault, road type, road geometric characteristics, education level of driver, and vehicle license type. Geographic Information System (GIS) has been used for the analysis and recording of fatal traffic accidents. Using GIS, the locations of fatal traffic accidents were drawn as points on the Amman City map. After locating the accidents in their proper locations, each year had a separate layer (theme) over the base layer (the map). After that, all other characteristics of the accidents were added. The results of analysis presented the major contributing factors of each of the above analysis elements.
Keywords: Accidents, Fatal Traffic Accidents, Geographic Information System, Countermeasures.

Abstract:-- This research aims to evaluate heavy construction companies in Brazil in order to measure how it is manage the risk in projects, which practices are used and how it is reflected in their results. For greater assertiveness in this research, was performed a multiple case study with ten heavy construction companies involving construction projects such as ports, power plants, railways, roads, among others. The main results reveal gaps between best practices and the risk management in the development of these projects. One of the conclusions is that the guides PMBOK and FEL used in parallel collaborate for a positive impact in the effectiveness of the results. However, risk management in these projects still need improvement given that, through empirical research, 100% of the Brazilian companies in this industry are performed with extrapolation of the budget and the deadline.
Keywords: Heavy Construction, Project management, Risk analysis.

Abstract:-- The world is centered on a period where the current generation is consuming future generation’s environmental resources. Buildings construction and use can be considered among the largest natural resources consumers. Public buildings construction should incorporate eco-efficiency’s attributes in their projects, which would result in less environmental impacts, more environmental preservation and also save public resources during the period of their operation, use and maintenance. The objective of this study is to identify which of the eco-efficiency´s attributes should be an essential part of public buildings, in ways that they could become environmentally sustainable and also meet legislation´s requirements. The methodology included literature review and a survey employing questionnaires sent to experts in the fields of architecture and engineering. Statistical analysis of data showed that, out of the 40 attributes of eco efficiency evaluated, 27 were considered essential and 13 were considered important. The essential attributes should be included in public building’s projects in Brazil.
Keywords: Eco-efficiency, Public buildings, Sustainable construction.
