Factors Influencing Integrated Project Delivery in Publicly Owned Construction Projects: An Information Modelling Perspective

Abstract

The objective of this paper is to underline the factors influencing the implementation of integrated project delivery (IPD) in public sector construction projects. These factors are broadly classified under legal, organizational and technological categories. Further the role of information modeling to foster the integration in project delivery is discussed. Focus is placed on the aspects/characteristics of information modeling that can contribute to implementation of integrated project delivery. Traditional project delivery methods have been found by researchers as inefficient and litigious. As a result, the construction industry is in a critical need of alternative delivery methods.IPD has emerged as a solution, although its implementation is not without challenges. Therefore factors influencing its implementation should be identified as a step towards its probable use in the future for public-sector construction projects. Owners, particularly the public ones, are apprehensive due to various factors. The purpose of this paper is to investigate these factors and suggest an information modeling approach to overcome the impediments.

Construction Project Delivery System Selection Framework: Professional Service Firms’ Perspective

“…2.1.5 IPD In recent years, IPD has appeared as a method that has the potential to reform project delivery [12]. It differs from other project delivery methods by focusing on the general improvement and the integration of processes, tools, and people in a single system [12].…”

“…It differs from other project delivery methods by focusing on the general improvement and the integration of processes, tools, and people in a single system [12]. This integration exploits the participants' abilities and insights to decrease waste and optimizes efficiency through the different stages of design, fabrication, and construction [22].…”

“…A primary advantage of IPD is the capability of all parties to take part in the project as early as the design stage [23]. Collaboration of all parties represents a significant component of IPD [12,22]. The IPD construction method starts from the concept stage through to the handover and operation stage with the aim of achieving a building under the integration of the design team, owner, and contractor [24].…”

“…Traditional PDSs such as DBB (design-bid-build) that mainly focus on mutual contracts and the lowest bid do not support collaboration, as project stakeholders attempt to maximize their operations and risks [11]. Moreover, researchers perceive traditional PDSs as inefficient and controversial [12]. Thus, there is a significant need for alternative PDSs in the construction industry [12].…”
