Abstract: This paper investigates the challenging environment of reconstruction projects and describes the development of a predictive model of cost deviation in such high-risk projects. Based on a survey of construction professionals, ...

Abstract: As compared with new construction, reconstruction of operational facilities exhibits a higher challenge, particularly when multiple projects are involved. For owner organizations involved in such projects, use of in-house ...

Abstract: The total value of civil infrastructure (roads, buildings, and underground services) in North America is estimated at $20 trillion. Due to its large size and the need for minimal interruption to services, maintaining the ...

Abstract: Cost, schedule, and quality are the main indicators of performance in construction projects. These indicators are highly interrelated and require some balance and trade-off among them to achieve efficient overall control ...

Abstract: The heat transfer intensification of a confined impinging jet was achieved using a rough surface or pin fins as well as using modified nozzles such as chamfering, chevron, sweeping, swirling, etc. In this work, an enhanced ...

Abstract: The lack of quantitative data relating initial investment to long-term costs has raised concerns about green buildings’ long-term economic effectiveness. This study analyzed the operating, maintenance, rehabilitation, and ...

Abstract: The aging infrastructure in North America and worldwide mandates large investments in repair and improvement (R&I) activities. For organizations that own many assets, managing a large number of R&I activities is not a ...

Abstract: Numerical study of the effect of jet position (JP) on cooling process of an array of heated obstacles simulating electronic components has been investigated based on realizable k–ε model. Jet positions have been changed ...

Abstract: The paper describes a method of inelastic analysis for steel frames that provides the accuracy of distributed plasticity methods with the computational efficiency of elastic‐plastic‐hinge methods. It accounts for ...

Abstract: In this study, the cooling of a gas turbine (GT) blade leading edge using a single row of five impinging air jets was numerically and experimentally investigated. The inner surface of the blade leading edge was depicted ...
