Abstract: Variations in labor productivity are the result of multiple influential factors. This paper attempts to develop a labor productivity model based on multilayer feedforward neural networks trained with a backpropagation ...

Abstract: All over the world, limited funding for the development and operation of infrastructure projects propels governments to attract private investment and enter public–private partnerships (PPPs). Different types of PPPs have ...

Abstract: Time, cost, and quality are three major competitive objectives of every project, among which creating a balance through optimal resource utilization, results in desirable project performance. To address this issue, as an ...

Abstract: In the construction industry, one of the most important concerns of organizations is how to achieve a balance between the desired level of quality and the expenses associated with it. The evaluating of the cost of quality ...

Abstract: Infrastructure systems play a critical role in creating a livable environment for human societies. Hence, enhancing the resilience of infrastructure systems against the adverse impacts of disasters has become a prominent ...

Abstract: Changes often have significant and unpredictable effects on construction projects. There are numerous kinds of changes that can occur in construction projects. This research considers changes that have negative effects on ...

Abstract: Changes are realized as the most common issues during the life cycle of any construction project which may have significant effects on project objectives. Developing a proactive change-management system may decrease the ...

Abstract: Project life-cycle cost analysis (LCCA) is a reasonable approach to compare pavement design alternatives, but not taking into consideration of pavement performance in the most LCCA approaches may lead not to obtain the ...

Abstract: Budget deficits or owners’ cash-flow problems are often blamed for construction delays and construction cost increases that may be caused by these delays. Although many studies have focused on resource allocation, cash-flow ...

Abstract: Although prior research has examined the influence of site supervision on construction safety, a comprehensive systems-level perspective incorporating interdependent relationships among key variables has yet to be fully ...
