In the Integrated Project Delivery (IPD) approach, partner selection, contract signing as well as the signing of participants’ task scope, and the setting of incentive plans usually take place before the design of a project has been completed. This brings risks and uncertainties to project management. To overcome these challenges, the proposed framework for risk sharing strategies in IPD projects should consider four levels that interact in the system: (1) risks in goal achievement (such as cost overruns); (2) risks that occur during the project management process; (3) the incentive mechanism; and (4) participants’ decisions. In the study described in this paper, the interaction of the participants’ decision-making in situations of risk and the factors affecting the interaction were identified and modeled for IPD projects. The equilibria were calculated using game theory, and simulations were carried out to showcase the interaction process and the factors that influence participants’ decision-making and project performance. An epidemic model, network analysis, and regression analysis were also used for the simulation and analysis of risk propagation on the risk network. Furthermore, strategies to improve project performance and mitigate risk propagation were developed. In theory, this paper fills the gaps in previous research and proposes an approach for further research on risk sharing practices in IPD projects. The findings are also helpful to practitioners of IPD projects for risk analysis, partner selection, team building, setting of incentive mechanisms, and handling of project risks.

Decision Support System for Optimum Soft Clay Improvement Technique for Highway Construction Projects - 01/0

Rana Nabil Fatouh Khallaf

01/03/2020

Identifying a soft clay improvement strategy is a main challenging in highway construction projects due to the various conditions involved. Hence, the objective of this paper is to present a Decision Support System (DSS) to select the optimum soft clay improvement technique for this type of projects. Value Engineering (VE) is integrated with Analytical Hierarchy Process (AHP) for the proposed (DSS). Using the AHP provides a robust means of identifying the relative importance of any criteria or factors for soft clay improvement alternatives. The scope of this study includes four of the most commonly used techniques for soft clay improvement: soil replacement, pre-loading, vertical drains, and the construction of embankments on piles. The proposed methodology was verified using four case studies of highways under construction in northern Egypt. The results show that the proposed (DSS) successfully predicted the optimum soft clay improvement technique in three out of the four cases.

Kamel, M., Habib, O., Farahat, M.

01/12/2019

Tolerance in the construction industry has been regarded as a vague topic due to the paucity of information available on it. As a result, the effect of tolerance and its impact on a project has been neglected in many cases. This impact can sometimes be catastrophic to the testing and commissioning phase of the project and the overall project quality as well. Tolerance management as a science focuses on the acceptable margin of error or discrepancy. One of the main objectives of this paper is to raise awareness about tolerance in construction and how to approach tolerance failures and defects to reduce/eliminate waste. This paper focuses on tolerance management and addresses how it can be applied in the construction field. Literature review was conducted to collect data on tolerance management in various fields and report on its main principles. This paper also introduces two terms: tolerance failure and defects, and discussed the relationship between them. Furthermore, five categories of tolerance failures are introduced. Finally, preliminary solutions and mitigation strategies for tolerance failure categories are proposed.

One of the main issues that impact the construction industry is the prevalence of wastes. These wastes have negative effects on the project including higher cost and need for larger inventory. One of the main tenets of lean is to eliminate these wastes in order to increase the value to the customer. This paper focuses on lean applications in construction projects, specifically on how to identify and classify wastes, and how to eliminate/reduce them. Firstly, literature review is conducted to collect the different classification of wastes in construction. This is followed by a discussion of the eight types of wastes identified in context of construction projects and an application to a real-life case study, the Porto Sokhna Project in Egypt. This is done to identify wastes that occurred and their impact as well as propose elimination/mitigation strategies. Project documents were analyzed and interviews were conducted to reach this. These wastes were then classified under eight main waste types. The effect of these wastes was then monitored and recorded in terms of cost and schedule. Finally, solutions were proposed to eliminate/mitigate the wastes.

The Last Planner System (LPS) has been the focus of several studies in the Lean Construction community. Previous research has focused on defining lean in construction, its implementation in various projects, and the challenges facing the implementation. However, no research has addressed lean implemen-tation in Egypt. Therefore, this paper addresses the obstacles facing LPS adop-tion in the Egyptian construction industry and proposes a framework for LPS implementation in Egypt. A questionnaire survey is carried out involving a num-ber of construction industry stakeholders to identify the current market knowledge on LPS and the challenges expected from its implementation in Egypt. The proposed framework details the techniques to be followed during the project life cycle and how to measure the effect of LPS on the overall project performance. The framework also tackles the expected challenges and proposes key solutions for each one. This paper aims to push the boundaries of the current state of the construction industry in Egypt by proposing the implementation of LPS and the steps needed for its adoption in Egypt

The purpose of this paper is to build upon the extensive application of risk registries in the construction literature and establish a systematic methodology to develop risk registries. Risk registries channel judgment of experts as a basis for risk analysis and should be tailored for each project to be more effective. Given their prevalence, there is a need for systematic integration of tacit and explicit knowledge to develop practical risk registries.

Public–private partnerships (PPPs) involve a variety of project governance structures. Common among all these varied structures is the long-term contractual period between multiple public and private entities. The increased uncertainty of a long-term contract duration coupled with the involvement of multiple stakeholders proves to be a challenge to the development of risk strategies for PPPs. Therefore, it is necessary to systematically frame the risks associated with these projects and explore their dynamics. These risks often arise due to the organizational dynamics from the interactions between stakeholders in varied risk scenarios. In this paper, a methodology is proposed to systematically identify risks in PPP projects, model the organizational dynamics associated with interactional risks using game theory, and simulate these models to observe a range of potential outcomes. The proposed combined approach can help planners prepare for a range of complex and uncertain scenarios and enable stakeholder management in PPP projects. The current literature is extended in this paper by (1) integrating risk identification and framing with modeling and simulation, and (2) expanding the analysis of interactions from the current focus on two parties to three. A case study of the Indiana Toll Road is performed to showcase the application of the proposed approach.

The main purpose of this paper is to introduce the framework of Systematic Literature Review (SLR) as a methodology for research on risk identification. Risk identification is a long and tedious process that often lacks a systematic approach. Therefore, there is a need for a methodical technique to minimize bias and streamline the process of data collection and refinement in risk analysis research. Systematic Literature Review has been used vastly in fields such as software engineering and medicine but has yet to spread to construction management. This paper proposes a framework for application of Systematic Literature Review in the risk identification process of construction research and practice. In order to showcase the proposed methodology, a case study is presented where Systematic Literature Review is applied to identify risks in PPP projects in order to showcase this methodology

Infrastructures have been known to show interdependent relationships amongst each other, which manifest especially in cases of natural disasters. These interdependencies may affect their serviceability and ability to return to their original status. There is a need to identify the interdependencies amongst these critical infrastructures especially in order to understand the dependency and plan mitigation strategies. Previous literature has focused on specific case studies of natural disasters or identifying theoretical frameworks for the critical infrastructure interdependency. Hence, a methodical approach is needed to identify critical infrastructure interdependencies in cases of natural hazards and extract patterns among them. Systematic Literature Review (SLR) is a structured and methodical approach to answer questions in a research. This paper applied SLR for collecting appropriate infrastructure interdependency articles and case studies and identifying patterns of multidimensional infrastructure interdependencies and layers. One of key findings in this paper is that civil infrastructures are attributed more to the physical services/functions/material supply interdependencies whereas civic infrastructures are more associated with informational, logical service supply interdependencies. The findings are expected to assist decision makers in prioritizing the infrastructure types and layers for disaster mitigation and response plans.

Public private partnerships (PPPs) have spread from their typical use on infrastructure projects such as roadways and water sanitation to their more recent use for projects in higher education institutions such as universities and colleges. These PPP projects have diverse attributes depending on the type of project, institutional culture, and structure of ownership and management. Based on these key aspects, the projects can either be successful or unsuccessful depending on economic and financial measures. This paper investigates the use of PPPs for the delivery of higher education institutions and finds trends of PPP usage in the United States. This is performed by first collecting records of PPP projects in educational institutions by applying the systematic literature review (SLR) methodology. The result of the SLR methodology is a collection of U.S.-based higher education PPP projects and a classification of project types and where they are located. The results at this stage show that PPP projects have been used the most in the South and Northeast as compared to other geographic locations in the U.S. majority of the projects were student housing complexes for the universities and there has been a trend for expansion to other areas such as utilities, parking garages, and health centers. The results also show an increasing trend in project sizes between 1994 and 2017. This paper provides a detailed review of the use of PPPs in higher education institutions with a focus on how SLR was conducted and the identified trends. It was noticed that PPP was not only used by public universities, but also spread to private universities. The results of this paper are expected to shed light on the increased PPP usage in the educational sector in the U.S.

A Risk Registry for Renegotiation in Public Private Partnership Projects: ICRAM-PPP - 01/0

Naderpajouh, N. and Hastak, M.

01/06/2016

The use of public private partnerships (PPP) as a project delivery method has passed its maturity stage as numerous PPP projects are already in the later stages of the concession period. Observation of the dynamics of PPP during this period suggested risks associated with renegotiation as the primary challenge. Renegotiation risks originate from various sources, which can be associated with the interaction of different actors within the public and private parties. In this paper, a registry framework for risks associated with renegotiation in PPP is proposed. The framework is based on the international construction risk assessment model (ICRAM-1) which grouped risks of international construction into three levels: macro level consisting of general risks associated with work in a specific country, market level consisting of risks emerging from the global construction market, and finally the project level. A systematic literature review was conducted to code risks associated with renegotiation. This coding was then contrasted with ICRAM-1 to develop a framework specific for renegotiation in PPP. The review included the research studies and models as well as case studies of PPP around the world. Finally, a hypothetical example of simulating risks identified through this framework is presented to showcase its application.

Public Private Partnerships (PPP) have been increasingly used over the past years. However, problems have arisen with the increased use of this procurement strategy. These problems usually occur as a result of various risks that manifest over the long duration of the project. These include risks at the macro, market and project level specific to PPP projects. Examples include concessionaire default in loans for the Sydney Airport Rail Link project, bank refusal to loan the concessionaire for the Channel Tunnel Rail Link project in the United Kingdom and high interest loans on private debt for the Taiwan High Speed Rail project. Identifying risks in previous projects would lead to a risk registry that would help in understanding the sequence of events as well as the parties involved. Case studies have suggested that the outcome of the identified risks can be linked to the interaction of the parties in a PPP project. Parties to the risk in a PPP project include owner or government, developer, financier, sponsor, supplier, architect, subcontractors, contractors, non-governmental organizations (NGOs), media, authorities and regulatory, politicians, workers, end-users and experts. In this paper, game theory is used to analyse the interactions between parties to understand dynamic outcome of the associated risks in PPP project because of the actions taken by the parties to the risk. The scenarios of risks are defined based on actions and their transaction cost as well as outcomes and th
