PROFIT DISTRIBUTION IN IPD PROJECTS BASED ON WEIGHT FUZZY COOPERATIVE GAMES

Integrated Project Delivery (IPD) is regarded as an effective project delivery method that can deal with the challenge of the rapid development of the architecture, engineering, and construction (AEC) industry. In the IPD team, the alliance profit is not distributed fairly and effectively due to uncertainty, preventing the achievement of the IPD project goals. This study focuses on optimizing the profit distribution among stakeholders in IPD projects and uses quadratic programming models to solve fuzzy cooperative games in the IPD. A payoff function is used in the fuzzy alliance to determine the characteristics of the interval-valued fuzzy numbers, and different weights of the alliance and the efficiency of the player’s participation in the IPD are considered in the profit distribution. A case study is conducted, and the results of the proposed method are compared with those of crisp cooperative games. The results show that the fuzzy cooperative game increases the profit of participants in IPD projects. It is more practical to use weight fuzzy cooperative games than crisp games to express imputation. Moreover, the quadratic programming models and methods result in a fair and efficient profit distribution scheme in IPD projects.

Documenting the Interactive Effects of Project Manager and Team-Level Communication Behaviors in Integrated Project Delivery Teams

This study examines the influence of project managers’ communication behaviors in integrated project delivery (IPD) projects. This study also considers the impact of team-level information sharing on team-level outcomes (i.e., goal alignment, decision quality, process commitment, and project quality). Results indicate that team information sharing was perceived as beneficial, but the effects of project manager communication behaviors were inconsistent. Interaction analyses indicated that project managers’ communication behaviors hindered team functioning if teams were already engaging in adequate levels of information sharing. This manuscript contributes to the project management corpus by explicating an integrative model whereby project manager and team-level information-sharing behaviors are modeled simultaneously.

Trends of integrated project delivery implementations viewed from an emerging innovation framework

PurposeResearch into integrated project delivery (IPD) has attracted increased attention over the past 2 decades, and a significant number of IPD studies have been published more recently. The purpose of the study is to explore the state of IPD to reveal innovative areas of focus.Design/methodology/approachThe research presented puts forward a science mapping and bibliometrics methods to study systematic analysis of IPD scientific output published between 2006 and 2020. It uses a framework from emerging literature relating to innovation to incorporate a perspective of the process of innovation for the analysis of IPD. The adapted framework from the literature on innovation, called the Technology Innovation System (TIS), has functions that reveal novelty in the existing structures of IPD. The framework uses the analysis of scientific output from science mapping and bibliometric study techniques, using the ScienceDirect (SD) and Web of Science (WoS) databases as sources. The framework analyzes factors involved in the development and diffusion of the IPD approach and charts new knowledge development on IPD.FindingsFrom the analysis, future implementation of IPD will converge on cases of collaboration, as a systemic feature, among participating stakeholder teams. A significant and robust effect resulted from collaboration and integration as major mechanisms influence opportunities, problems and solutions within construction firms using IPD, marking a future trend. Reports further substantiate the importance and focus on collaboration and integration between IPD practitioners. With the same dynamic and gradual prominence, building information modeling (BIM) and new technology applications demonstrated the importance of the development and diffusion of IPD in the form of, for example, digital government initiatives. It is expected that the trend for IDS and resource mobilization functions will continue to grow – clear evidence of the benefits of the IPD approach in the construction sector. New evidence for gaining cognitive and normative legitimacy emerged. The expansion of new avenues for further legitimation is expected to enable growth.Research limitations/implicationsBeyond the innovative approach of viewing IPD from the emerging innovation framework, the research presented fully contributes to IPD literature, providing a comprehensive state-of-the-art status and a quantitative analysis of IPD scientific output, thereby illuminating promising work areas for future research into IPD. The main limitation is related to the dynamic process of indexing of IPD literature in the WoS and SD – although many new research publications are added in the discipline, only a part of them have been indexed in the WoS and SD core database.Practical implicationsThe study revealed key evolving trends within the field, including instructive findings and implications concerning possible deficiencies. Based on factors from network visualizations and quantitative evaluation from major influential articles, journals and authors, future critical IPD implementation focus will be on BIM and sustainability concepts – centerpiece concepts for the evolving line of IPD growth and development in the architecture, engineering and construction industry.Social implicationsThis study fills the gap created in a shortage of studies mapping out the most critical contributions in journals, authors and research perspectives related to IPD. It presents a framework that can be used as an objective procedure to evaluate the topic. It is expected that the study will serve as a cornerstone for researchers in this field, as it provides a bibliometric analysis and presents trends using an analytical framework of innovation.Originality/valueThe research presented is a keystone in the foundation of the literature review on this topic. The research draws on an existing framework for innovation – the TIS, developed from innovation studies using a robust theoretical framework to enable further analysis of IPD. This approach is one of a kind, using the results of scientometric analysis to study the scientific landscape and knowledge output of IPD in the AEC community. Science-mapping bibliometric analysis was conducted to shed light on IPD trends and explain factors that back or support the development and diffusion of IPD, including shaping and enabling evolution and growth. The framework helps to shed light on the interaction of socio-technical structures (i.e. stakeholders, technologies and rules) embedded in the industry, which helped create, direct and advance IPD in the project delivery system.

Application of BIM with IPD in Design for a Construction Project

Integrated Project Delivery (IPD) is a new delivery system that fosters integration of combining design and construction in a collaborative team environment. Building Information Modeling (BIM) is a smart technological tool that make significant advancements in coordinating the planning and construction processes. IPD process with BIM technology allows all building data to maintain in a communicating platform that make all participants share data. In reality, some technical and process obstacles exist, that are hampering full implementation of IPD with BIM in the project. The paper introduced the application of IPD with BIM on the design in a project. The results showed the impact of BIM implementation on IPD mode which can result in improved productivity, better coordination, reduced energy consumption, clash and rework of construction.

Integrated Project Delivery with BIM: A Methodical Approach Within the UK Consulting Sector

The aim of this study is to identify the advantages and limitations in the implementation of the Building Information Modelling (BIM) and Integrated Project Delivery (IPD) in the UK consulting sector. A literature review critically analyses the existing literature, (including online articles and publications owing to the current and fast-moving nature of the topic in question). Next, a qualitative research approach was employed through interviews which targeted BIM professionals across the AEC sector in the UK. Barriers to BIM were found to include lack of enthusiasm for potential opportunities for BIM and IPD. Cultural factors which act against BIM and IPD implementation include, willingness to adopt BIM environment, software cost, high-end user maintenance cost. Furthermore, a need was determined for UK government support and encouragement for the use of BIM and IPD for smaller projects. This study recommends that schools take steps to improve career advice and guidance for students in relation to construction, specifically increasing awareness of the opportunities available related to BIM and working professionals to increase awareness of and employment in BIM through training and apprentices as appropriately. Finally, the paper concludes that BIM and IPD should be more widely adopted within AEC industries in the UK to maximise benefits from both systems.

Feasibility of implementing IPD approach for infrastructure projects in developing countries

Alternative project delivery approaches have been proposed to overcome the inefficiencies of conventional delivery methods such as design-bid-build. Integrated Project Delivery (IPD) has recently emerged as a feasible substitute to traditional project delivery approaches. Despite widespread awareness of the benefits of IPD in integration with information and communication technology (ICT) to enhance the delivery of construction projects, IPD implementation has so far been sluggish in developing countries such as India. The feasibility of implementing IPD approach and applying its principles is investigated in this study. It assesses the maturity of delivery techniques, and the potential benefits and limitations of using IPD for infrastructure projects in developing countries, using India as a case study. This study has been carried out using an in-depth investigation of the literature in combination with a qualitative method involving interviews with ten highly experienced BIM professionals from the Indian AEC sector. The findings of this study have revealed that adopting integrated project delivery while leveraging the BIM process in conjunction with ICT has the potential to effectively deliver mega infrastructure projects in developing countries. The resistance to change, lack of experience and skills, and lack of awareness among project owners are recognized as the primary obstacles to IPD adoption. The main benefits for practice following adoption could include enhanced project delivery, more effective coordination among stakeholders, and greater transparency with cost and time savings through all stages of the project. It is recommended that the regulatory bodies establish governing standards and frameworks, amend regulations to accept IPD concepts, and upskill the workforce through training and knowledge transfer for its successful adoption. One novel aspect of this study may be recognized since most previous research has focused on limitations, benefits, and adoption frameworks for IPD whereas there has been no definitive study on the practicality of IPD combined with BIM and the use of ICT for successful infrastructure project delivery in developing countries. This study contributes to the body of knowledge by serving as an exemplary paper for future studies on the adoption of BIM and ICT approaches such as cloud computing, blockchain, IoT, and mixed realities to deliver projects with integrated project delivery. Furthermore, it provides a deeper understanding of the future of this delivery approach in developing nations.
