Abstract
There is a lack of an efficient systematic approach to the selection of appropriate construction methods for building projects. Not only various innovative methods are now available, but also established methods may often be adapted inappropriately, without recourse to the necessary scientific foundation of their efficiency. The result is that there is a low level of performance on building projects. This study examines how key performance criteria were used in the selection of construction methods on projects. The study employed an extant review of the literature, cross-section survey of construction managers of building projects and experts interview in the Middle East to identify and evaluate the influencing of the key performance criteria on selecting construction methods for building projects. It emerged from the Pearson Correlation Coefficient and Analytical Hierarchy Process analysis that key performance criteria consisting of time, quality, and cost have strong positive significant roles in the selection of construction methods used on building projects and that these selection criteria differed depending on the building components. The study concludes that the likelihood of a construction method being selected for use on projects in the Middle East depends on its ability to shorten the duration, improving the quality and reduce the cost of projects.
Highlights
IntroductionIn the construction of buildings, there are common problems and challenges of a low level of productivity and efficiency
The primary purpose of this study is to evaluate the key performance criteria influencing the selection of construction methods, which are currently being used on building projects in the Middle East and whether the selection criteria differ according to building components
This study examines how key performance criteria were used in the selection of construction methods on projects and whether these selection criteria differed across different building components toward making recommendations for improving the selection of appropriate construction methods on projects
Summary
In the construction of buildings, there are common problems and challenges of a low level of productivity and efficiency. Kamali et al [2] and Ren et al [3] found that different construction methods influence project performance in various ways and impact on the productivity of construction projects; deficient methods decrease the productivity of projects. Forbes and Ahmed [4] posited that the choice of construction method significantly impacts on the cost, time, and quality of buildings, and adopting inappropriate methods increases the cost and duration of projects, as well as decreasing the quality and lifespan of buildings. The construction industry has been revolutionized and is experiencing changes, with the rapid growth of technology and the introduction of new building materials and modern construction methods [5]. To achieve construction project performance objectives, there is a need for adequate information and knowledge to help construction managers to make good choices of construction methods
