Abstract
Selecting the appropriate project delivery method (PDM) is a very significant managerial decision that impacts the success of construction projects. This paper provides a critical review of related literature on the evolution of project delivery methods, selection methods and selection criteria over the years and their suitability in the construction industry of today’s world. The literature review analysis has concluded that project delivery methods evolve at a slower rate compared to the evolution of the construction industry. The paper also suggests features of an evolved project delivery method that is digitally integrated, people-centered, and sustainability-focused. Moreover, the paper highlights the latest selection criteria such as risk, health and wellbeing, sustainability goals and technological innovations. Furthermore, the paper concluded that advanced artificial intelligence techniques are yet to be exploited to develop a smart decision support model that will assist clients in selecting the most appropriate delivery method for successful project completion. Additionally, the paper presents a framework that illustrates the relationship between the different PDM variables needed to harmonize with the construction industry. Last, but not least, the paper fills a gap in the literature as it covers a different perspective in the field of project delivery methods. The paper also provides recommendations and future research ideas.
Highlights
The construction industry is a major contributor to any country’s economy
The aim of this paper is to conduct a systematic literature review on the project delivery methods available in the construction industry, the selection criteria that are identified in the literature, as well as the selection models and decision support tools used by owners to choose the appropriate project delivery method
Like the age of information technology arrived by the year 1975, the decision-making tools grew more sophisticated with the introduction of multiattribute utility theory (MAUT) and analytical hierarchy process (AHP) to help improve the objectivity of the selection process and make it less subjective
Summary
The construction industry is a major contributor to any country’s economy The impact of this contribution largely depends on the successful and efficient delivery of construction projects. One of the critical success factors in any construction project is the managerial decision of the project delivery method [1]. This is due to the fact that it has a direct effect on key performance indicators such as cost, schedule, quality, project execution and safety [2]. CMR is a delivery method in which the construction manager is recruited during the design phase of the project, giving him the responsibilities of both a project coordinator and a general contractor [5]. Collaborative delivery methods such as integrated project delivery, alliancing and partnering represent emerging forms of delivery methods that emphasize features such as collaboration, trust, commitment, as well as co-learning [6]
