Problem statement: Each year, a major part of revenues spent on Investing in sector
development plans and State infrastructures filled with clear reduce costs and done on time Projects
leading to high savings budget plans executive and will be return on Investment. Approach: On
transportation projects, Value Engineering (VE) teamwork by involving construction, design and
maintenance staff review the construction project features and look for ways to improve quality,
control costs and time. Also this study briefly described VE and quality, cost schedule planning,
application of VE, cost parameters, relationship of value, function, cost and worth. Results: VE,
highway construction was survived and opportunities for better, less expensive means of completing
the construction projects were analyzed. The intention is to progress project quality and productivity,
foster innovation, optimize design elements, also ensure overall economical costs. Conclusion: This
study achieved to the model Value Engineering in Highway Construction (VEHC) which cause
decrease time, decrease cost and increase quality in highway it has been
Abstract. Construction delay is a common problem in the construction industry all over the world. Many researchers seeking the causes of delay in order to reduce the probability of delay to occur. Most researcher identified causes of delay in construction to reduce the possibility of construction project to continued delay. This study is to obtain the holistic delay categories base on Drewin Open Conversion System (DOCS) for the development of a theoretical framework delay and to get the most significant causes of delay in construction industries. There are three main factor of construction delay based on DOCS; input factor, internal factor and external factor. There are130 items on causes of delay and it is divided into 31 categories. This pilot survey is distributed to students and fresh graduates that have educational background in construction. The result shown the main factor that contributes to construction delay are mistakes during construction and unrealistic project durations.
Many researchers, in the recent years have developed various techniques for determining water content of the soils. Electrical Capacitance Volume Tomography (ECVT) is one of the techniques developed by using various types of sensors to improve the quality and effectiveness in the determination of water content in the soil. The technology is based on the capacitance measurement generated from a whole volumetric image of the region which is surrounded by three-dimensional geometry capacitance sensor. This study was carried out to determine the effectiveness of ECVT in measuring soil water contents in fine sand and silty sand to compared with the gravimetric method. Results analysis show that the correlations of the water content measurement R2 using ECVT and gravimetric methods for fine sand and silty sand are very good, about 0.978 and 0.988, respectively. These suggest that ECVT method has a good potential in determining the soil water content in this respective soil type.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
