    Abstract: In the present paper, a cost-risk and income-risk evaluation model has been developed in order to evaluate the risks of cost and incomes those may happen in construction projects. Since, it is important to determine risk factors for different activities and stages of various projects; the main aim is to propose an evaluation model for estimating th... Show More

    Abstract: Pre-design Geoelectrical and River Velocity studies have been carried out at two bridge locations: Ebonyi River at Onicha-Oshiri road and Ebonyi River at Idembia Ezza. The objectives of the studies are to determine the geoelectrical parameters with respect to structure and rock type at these locations in combination with geology and carry out the a... Show More
  • Environmental Risk Management and Mitigation Strategies for Offshore Gas Well Drilling Projects (Case Study: Abu Qir Bay, Egypt)

    Abstract: Risk evaluation for offshore gas exploration and production is a challenging task because much of the available data are highly uncertain and vague, and many of the drilling techniques are complex. The paper describes the implementation and use of environmental risk management and mitigation strategies for an offshore gas well drilling project. It ... Show More

    DOI: 10.11648/j.jccee.20170202.15
    Abstract: This research tends to raise the accuracy of absolute point positioning by simulating the differential positioning mode. This process was done by observing the unknown point using one unit GPS receiver after observing the fixed point with the same receiver and estimate the Doppler value; where it equals to the expected change at carrier phase measu...
