An FCM-based dynamic modelling of integrated project delivery implementation challenges in construction projects

Question: What are the Integrated Project Delivery Implementation challenges in construction projects, their interrelationships and their effects on the project time, cost and quality? Purpose: The Purpose of this study is applying an efficient method to determine the most important challenges to IPD implementation in construction industry, and also to evaluate the interrelationships among these challenges and their effects on the project time, cost, and quality. Research Method: This study models available Integrated Project Delivery challenges using a real case data, through applying Fuzzy Cognitive Mapping technique. Findings: Results show that contractual factors have the major influence compared with others. This shows the significance of paying attention to why project stakeholders must be integrated throughout the project life cycle since early contract documentation stage. Limitations/Implications: This study is limited to the case selected from Tehran of Iran. Value for authors: This study is significant due to identifying, classifying and determining the intensity of effects of IPD implementation challenges on cost, time, and quality of construction projects. It results in planning, resolving the challenges, enhancing the quality of constructions and lastly saving the construction cost and time

Integrated Project Delivery (IPD) Research Trends.

Integrated Project Delivery (IPD) is introduced as a vibrant approach to enhance project implementation, having particular position in recent studies among construction researchers. This study analyzes the research trends on the field of IPD to provide an appropriate vision for future researchers in this specialized field. While so far no comprehensive research has been done in this field, this study provides a comprehensive review of existing studies through in-depth literature review method. This research evaluates studies conducted in the field of IPD, which is a basis for future researchers to improve conditions of IPD implementation in different countries. For that this study Using library studies, the trend of researches conducted on various concepts and domains during various years, has been investigated. Future studies can simply use the outputs of this research to shape their research flow on establishing continuing progress of IPD. The data obtained from descriptive analyses are illustrated quantitatively, followed by comprehensive analyses and discussion of the results. Moreover, this study concluded that during recent years, the trend of studies conducted about IPD has increased, particularly articles examined challenges. In the next step, more studies have been performed in the field of construction. Those articles are preferred that have evaluated principles, challenges, and solutions for resolving barriers. Proper IPD implementation facilitates enhanced share of information and early identification of stakeholders through a proper timing as vital keys to realize objectives of the construction projects, reduce risks, and increase the chance of project success

An FCM-based dynamic modeling of operability and maintainability barriers in road projects

Building a new road infrastructure in the country leads to economic and industrial growth. A massive amount of money is paid by governments to build them; however, they fail due to many reasons related to operability and maintainability (O&M) issues. They are not also completed within the expected budget, time, and quality; so they are not justifiable. As these factors have a strong impact on projects, to reduce the final cost and other mentioned problems, it is necessary to identify the existing O&M barriers, their interrelationships, and their effects on the three mentioned factors. An in-depth literature review is conducted to identify the barriers. The fuzzy cognitive mapping (FCM) technique is used to model O&M barriers using real case data analyses. The findings reveal that managerial factors have more significanct impacts on the project’s success compared to other factors such as organizational, human resource, technology, and project management. Therefore, management methods are very important in developing integration in the project. Identifying, classifying, and determining the effects of barriers to entry of O&M contractors on the cost, time, and quality of road infrastructure projects show the signifcance of conducting this research, which is necessary to deal with the existing barriers. All these ultimately increase quality and reduce time and cost in road infrastructure projects
