Developing a framework for pre-design process simulation for green buildings
( American Society of Civil Engineers (ASCE) , 2012 , Conference Paper)There is an increasing awareness towards the construction of sustainable green buildings. Green rating systems worldwide, such as LEED, are providing standards to aid in the construction of green building. During the ... -
A multi-objective genetic algorithm model for time-cost trade-off analysis of construction projects
( Civil-Comp Press , 2006 , Conference Paper)Time-cost trade-off analysis is one of the most important aspects of construction project planning and control. There are trade-offs between time and cost to complete the activities of a project. Existing methods for ... -
Planning post-disaster reconstruction efforts of damaged transportation networks
( American Society of Civil Engineers (ASCE) , 2009 , Conference Paper)Planning, Reconstruction Efforts, Transportation, Network Analysis. Planning the reconstruction efforts of damaged transportation networks in the aftermath of natural disasters is a challenging task due to the limited ... -
Optimizing resource utilization during the recovery of civil infrastructure systems
( American Society of Civil Engineers (ASCE) , 2010 , Article)Postdisaster recovery efforts of damaged civil infrastructure systems need to be optimized in order to alleviate the adverse impacts of natural disasters on local societies and economies. This paper presents an innovative ... -
Integrated performance assessment model for water distribution networks
( Taylor and Francis Ltd. , 2016 , Article)The American infrastructure report card in 2013 rated the US water system infrastructure with grade of ‘D’. The Canadian infrastructure report card in 2012 stated that around 15.4% of Canada’s water infrastructure has a ... -
Measuring construction materials price fluctuation risk
( Canadian Society for Civil Engineering , 2013 , Conference Paper)Construction projects costs are believed to be highly susceptible to a combination of internal and external factors. One of these factors is the prices of construction materials and the risk of their fluctuation. This paper ... -
Multi-Criteria Decision Making Models for Water Pipelines
( American Society of Civil Engineers (ASCE) , 2016 , Article)The deterioration of water pipelines leads to impaired water quality, increased breakage rate, and reduced hydraulic capacity. The planning of maintenance programs for water pipelines is essential to minimize health and ... -
Locating leaks in water mains using noise loggers
( American Society of Civil Engineers (ASCE) , 2016 , Article)Because of their potential danger to public health, economic loss, environmental damage, and energy waste, underground water pipelines leaks have received more attention globally. Researchers have proposed active leakage ... -
Optimizing postdisaster reconstruction planning for damaged transportation networks
( American Society of Civil Engineers (ASCE) , 2009 , Article)The limited availability of reconstruction resources is one of the main challenges that often confront postdisaster recovery of damaged transportation networks. This requires an effective and efficient deployment and ... -
Use of local discarded materials in concrete
( Elsevier , 2014 , Article)Steel slag, a by-product of steel manufacturing, is generated in large quantities in Qatar. In fact, it is estimated that more than 400,000tons of steel slag are generated annually in the country. Gravel, resulting from ... -
Combined influence of temperature and flow rate of feeds on the performance of forward osmosis
( Elsevier , 2016 , Article)The effect of the membrane orientation, feeds flow rate, feeds temperature, and combining effect of both temperature and flow rate on the membrane flux was investigated in order to enhance the performance of forward osmosis ... -
Comparison of SimTraffic and VISSIM Microscopic Traffic Simulation Tools in Modeling Roundabouts
( Elsevier B.V. , 2015 , Conference Paper)Abstract SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation ... -
