Benefits of Using Constructability, Operability, and Maintainability in Infrastructure Projects: A Meta-Synthesis

Abstract

Planning and construction of infrastructure projects are increasing rapidly as the vital lifeline of countries for welfare and economic development; which considering cumulative population growth, they are in the center of attention more than ever. High investments, negative effects of early destruction and available duplications in these projects have enlarged necessity of focus on existing post design problems. In order to reduce problems of post design stages in infrastructure projects, constructability, operability, and maintainability concepts can be used in the initial pre-construction stage, which is a project management technique for reviewing post design processes from beginning to end. These concepts emphasize on early presence of construction, operation and maintenance contractors at the early phases of the project, so that through integrating knowledge and experience, reduce problems due to lack of applying them at the early stages of the project. Lack of comprehensive and centralized research that study benefits of applying these concepts, made researchers to conduct this project. This investigation, by the aim of evaluating benefits of applying these concepts in infrastructure projects and by using meta-synthesis method and utilizing qualitative analysis software NVIVO, has classified these benefits in different phases of the project life cycle. Finally, a classified structure of the benefits of implementing these concepts in different phases of the project has been provided; which by evaluating the obtained results and applying them, experts and various agents of the project can share their experiences and knowledge with each other efficiently. This study results in reduction of available problems due to lack of applying the concepts at the early stages of the project by highlighting awareness toward such brilliant benefits presented in the world investigations.
