A model for predicting failure of oil pipelines
( Taylor & Francis , 2014 , Article)Oil and gas pipelines transport millions of dollars of goods everyday worldwide. Even though they are the safest way to transport petroleum products, pipelines do still fail generating hazardous consequences and irreparable ... -
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 ... -
Analysis of change orders in Qatari construction projects
( Taylor and Francis Ltd. , 2017 , Article)Change orders affect the performance of construction projects and may induce significant cost overruns. The paper identifies the main causes/factors that lead to change orders in Qatari construction projects. It also ... -
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 ... -
Drift optimization of high-rise buildings in earthquake zones
( John Wiley & Sons, Ltd. , 2011 , Article)This paper presents a Drift Design Structural Model (DDSM) for the design optimization of high-rise buildings in seismic zones. The model is formulated as a Generalized Single Degree of Freedom System subjected to equivalent ... -
Effect of mixing duration on flexural strength of multi walled carbon nanotubes cementitious composites
( Elsevier Ltd , 2016 , Article)This paper investigates the effect of mixing duration on the flexural strength of multi-walled carbon nanotubes (MWCNTs) reinforced cementitious composites. Each batch containing 0.03%, 0.08%, 0.15% or 0.25% MWCNT to cement ... -
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 ... -
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 ... -
Modeling of the sustainability goal and objective setting process in the predesign phase of green institutional building projects
( American Society of Civil Engineers (ASCE) , 2014 , Article)The process of constructing a sustainable green building presents a number of challenges compared with regular buildings. Additional work and documentation is needed in every stage of the project life cycle for the sustainable ... -
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 ... -
Multicriteria Decision-Making Methodology for Credit Selection in Building Sustainability Rating Systems
( American Society of Civil Engineers (ASCE) , 2017 , Article)Uncertainty is an inherent characteristic of decision making related to sustainable construction projects. The main reason for this uncertainty is the incomplete information available to stakeholders on the relative impact ... -
Optimum Dispersion Parameters of Carbon Nanotubes: Concrete Strength by Response Surface Methodologies
( Qatar Univesrity Press , 2020 , Conference Paper)"This paper implements Response Surface Methodologies (RSM) techniques to illustrate the maximum carbon nanotubes (CNTs)-concrete mechanical properties responses to the length, weight fraction and treatment variables. ... -
Organizational behavior attributes and sustainable construction adoption: An econometric analysis using data from Qatar
( American Society of Civil Engineers (ASCE) , 2016 , Article)Despite the efforts of governments to promote sustainable construction practices, the decision to adopt sustainability practices largely falls upon the firms involved in construction projects. This paper presents an ... -
Performance of modified self-healing concrete with calcium nitrate microencapsulation
( Elsevier Ltd , 2017 , Article)This study investigates the strength reduction associated with incorporating calcium nitrate microcapsules in concrete. It also proposes modifications to the calcium nitrate micro encapsulation procedure to minimize the ... -
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 ...
