Dynamic approach for investigating delivery system effects on infrastructure project performance

PurposeInnovative design and execution approaches are employed in infrastructure sectors and planning to enhance the integrated project delivery system, assure the sustainability of infrastructure projects, and meet the demands of the dynamic, changing environment. Delivery methods must incorporate new technologies. By combining digital technology, teamwork, and mass manufacturing, a greater degree of exceptional quality, sustainability, and resilience in the environment will be generated. As a result, a new approach does not rely on the reaction policy, but instead considers alternative scenarios and employs a simulation model to determine the best course of action.Design/methodology/approachIn the paper, the system dynamics approach to construction management is validated in light of pertinent research. Additionally, it describes the difficulties facing the infrastructure projects' delivery system. Additionally, the strategy for system dynamics creation is described. This strategy includes a causal loop diagram, generates a stock-flow diagram, and simulates forecasts of model behavior over time. Next, the optimization model's validation process is used to create a system dynamics model for choosing the best infrastructure project delivery system project and controlling it to maximize sustainability, mass production, digital integration, and team integration. The dynamic complexity of project management is growing.FindingsThe primary goal is to present a system dynamics (SD) simulation to look at how well infrastructure projects perform in terms of choosing the best method for delivering infrastructure projects. One of the most ideal methods for delivering projects is integrated project delivery. An effective methodology for making strategic decisions on the choice of the best project delivery method. In order to enhance certain infrastructure project delivery system metrics for sustainability, mass production, digital integration, and team integration, the model included building strategy and sophisticated system dynamics simulation. According to the construction strategy, the outcomes have been satisfactory.Originality/valueSystem dynamics research has been done to replicate the idea of contemporary construction in order to determine the best approach for delivering infrastructure. The government and decision-makers would benefit from understanding this research as they decide on the best delivery method for boosting the sustainability and productivity of infrastructure projects in Egypt.

In response to the lack of any integrated courses of this nature, this exploratory case study involves the novel development of a university BIM-IPD-Lean Masters-level degree course. This was developed in four phases starting with an initial investigation by thorough contemporaneous review of the relevant education literature and in-depth research to determine the industry’s education requirements in full consultation with industry stakeholders, followed by a review of preliminary findings and obtaining approvals, major investigations and program structuring, final approvals and launch. 53 students graduated from the program, with every one becoming employed as a BIM professional within two months of graduation, with some employed during studies, and others immediately after graduation.

Training needs of built environment professionals: the role of fourth industrial revolution

PurposeStudies show that the twenty-first-century construction industry needs reskilling and upskilling tools to train large numbers of the workforce for better-integrated project delivery. Evidence shows that digitisation via the fourth industrial revolution (4IR) technology can play a critical role in reskilling and competency demand. Attempting to use digital technology may have had some challenges. Studies about the perceived hindrances facing Nigeria's built environment professionals (BEP) reskilling and upskilling needs in the workplace via 4IR technologies are scarce. Thus, the study investigated the perceived encumbrances facing Nigeria's BEP training needs and proffered measures to improve their performance in the workplace via 4IR technologies.Design/methodology/approachThe researchers engaged BEP in Lagos and Abuja, Nigeria. Regarding the data collection, a qualitative research design was adopted. The study achieved saturation after 32 virtual interviews. A thematic analysis was adopted for the collected data.FindingsThe study shows that using 4IR for reskilling and upskilling will enhance integrated project delivery. But the level of usage in training needs is low. Findings identified the various ways reskilling and upskilling could be achieved. Also identified are the major built environment areas that require 4IR training. Findings highlighted possible encumbrances facing the use of 4IR technologies by Nigerian BEP for reskilling and upskilling needs in the workplace and proffered feasible measures to improve 4IR usage for training needs.Research limitations/implicationsThe study is restricted to the perceived encumbrances and proffers measures to improve BEP reskilling and upskilling needs via 4IR technologies via a qualitative method. Future research is required to validate the findings and test the proposed framework that emerged from the study.Practical implicationsThe study confirms that reskilling and upskilling measures are required at all skill levels and may lead to economic growth. The paper would advance Nigerian higher educational accreditation agencies and various BEP regulatory bodies to review the curriculum and incorporate 4IR as a component or module.Originality/valueThe thematic network analysis and proposed framework could be utilised to stimulate Nigeria's BEP reskilling and upskilling needs in the workplace via 4IR technologies. It would stir main stakeholders, especially government policymakers, to facilitate programmes to improve 4IR technologies usage.

An Ontology to Represent the Prevention through Design (PtD) Concept in Integrated Project Delivery (IPD) in the Construction Industry from an Architectural Perspective

The Prevention through Design (PtD) concept has been widely used to mitigate potential safety and health hazards and minimize residual risks during the early design phase. Integrated Project Delivery (IPD) prioritizes project-wide collaboration and coordination; therefore, the importance of PtD has been widely recognized. There are still neglected issues pertaining to the implementation of the PtD concept from the architectural perspective. Hence, to fill this research gap, this review was motivated to highlight the ontological framework of PtD practices in the construction industry from the architectural perspective. The study is a thematic review aimed to synthesize the literature from 2011 to 2022 on the PtD concept from an architectural perspective. The study, using ATLAST.ti 8, a keyword search, followed by a filter using inclusion criteria from Scopus, Science Direct, Web of Science databases, and the snowball method, identified and analyzed 93 peer-reviewed journal articles. However, only 41 articles were used in the final review after the inclusion and exclusion process. A thematic review of these 41 articles identified five clusters representing the ontological framework findings, namely (1) designer competency, (2) planning and design decision making, (3) technologies related to building safety, (4) design features and workplace condition, and (5) laws and building legislation. The finding is expected to improve the understanding and implementation of the PtD concept to further develop an architectural safety design framework.

Dynamic evolution of the relationship quality among participants in integrated project delivery: based on supply chain theory

PurposeThe core of the successful implementation of the integrated project delivery (IPD) mode is to establish a high-quality relationship of cooperation, trust and sharing among participants. This paper proposes recommendations to improve the relationship quality of participants from the owner's perspective. The results provide the theoretical basis and practical guidance for the popularization and application of the IPD mode.Design/methodology/approachThis paper analyzes the dynamic relationship among participants in IPD mode based on supply chain theory and similarity theory. A tripartite game model of the owner, designer and the contractor is constructed to obtain the evolutionary equilibrium strategies under different parameter constraints. Then, numerical simulations under various scenarios are conducted to explore the dynamic evolution and the influencing factors of the relationship quality among the participant in the IPD mode.FindingsThe results show that (1) the relationship quality under certain conditions gradually improves as the project progresses until stable and high-quality cooperation is formed and (2) the owner's positive supervision cost, the distribution coefficient of incentive and punishment of participants and the scale of incentive pool are important factors influencing the relationship quality.Originality/valueThis study incorporates the following three innovations. First, analyzing the relationship quality among the participants of IPD mode based on supply chain theory. Second, the evolutionary game theory is applied to the relationship quality analysis. Third, conclusion innovation. The authors conclude that the relationship quality may progress, decrease or cycle with the progress of the project and targeted recommendations are presented based on the results.

A review of the interrelationships and characteristics of Building Information Modeling, Integrated Project Delivery and Lean Construction maturity models

PurposeThe application of integrated project delivery (IPD) in conjunction with building information modeling (BIM) and Lean Construction (LC) as the efficient method for improving collaboration and delivering construction projects has been acknowledged by construction academics and professionals. Once organizations have fully embraced BIM, IPD and LC integration, a measurement tool such as a maturity model (MM) for benchmarking their progress and setting realistic goals for continuous improvement will be required. In the context of MMs literature, however, no comprehensive analysis of these three construction management methods has been published to reveal the current trends and common themes in which the models have approached each other.Design/methodology/approachTherefore, this study integrates systematic literature review (SLR) and thematic analysis techniques to review and categorize the related MMs; the key themes in which the interrelationship between BIM, IPD and LC MMs has been discussed and conceptualized in the attributes; the shared characteristics of the existing BIM, IPD and LC MMs, as well as their strengths and limitations. The Preferred Reporting Items for Systematic Reviews (PRISMA) method has been used as the primary procedure for article screening and reviewing published papers between 2007 and 2022.FindingsDespite the growth of BIM, IPD and LC integration publications and acknowledgment in the literature, no MM has been established that holistically measures BIM, IPD and LC integration in an organization. This study identifies five interrelated and overlapping themes indicative of the collaboration of BIM, IPD and LC in existing MMs' structure, including customer satisfaction, waste minimization, Lean practices and cultural and legal aspects. Furthermore, the MMs' common characteristics, strengths and limitations are evaluated to provide a foundation for developing future BIM, IPD and LC-related MMs.Practical implicationsThis paper examines the current status of research and the knowledge gaps around BIM, IPD and LC MMs. In addition, the highlighted major themes serve as a foundation for academics who intend to develop integrated BIM, IPD, and LC MMs. This will enable researchers to build upon these themes and establish a comprehensive list of maturity attributes fulfilling the BIM, IPD and LC requirements and principles. In addition, the MMs' BIM, IPD and LC compatibility themes, which go beyond themes' intended characteristics in silos, increase industry practitioners' awareness of the underlying factors of BIM, IPD and LC integration.Originality/valueThis review article is the first of a kind to analyze the interaction of IPD, BIM and LC in the context of MMs in current AEC literature. This study concludes that BIM, IPD and LC share several joint cornerstones according to the existing MMs.

Benchmarking of construction projects performance for comparative assessment and performance improvement: a statistical quantitative approach

PurposeThe exact process of construction projects performance assessment and benchmarking still remains subjective relying on qualitative techniques, which does not allow stakeholders to address the issues and the drawbacks of their respective projects as effectively as possible for performance improvement purposes. Hence, this research aims to establish a unified project performance score (PPS) for assessing and comparing projects performance.Design/methodology/approachData were collected from Construction Industry Institute (CII) members and through University of Wisconsin active research projects. Exploratory data analysis was done to investigate the calculated performance metrics and the collected data characteristics. Data were converted into six performance metrics which were used as the independent variables in creating the PPS model. Logistic regression model was developed to generate the unified PPS equation in order to explain the variables that significantly affect construction projects successful post-completion performance. The PPS model was then applied on the collected dataset to benchmark projects in terms of project delivery systems, compensation types and project types in order to showcase the PPS capabilities and possible applications.FindingsThe model revealed that construction cost and schedule growth are the most important metrics in assessing projects performance, while RFIs’ processing time and change orders per million dollars were the features with the least effect on the PPS value. The authors found that integrated project delivery (IPD) and target value (TV) projects outperformed all other project delivery and compensation types. While, industrial projects showed the worst performance, as compared to commercial or institutional projects.Originality/valueThe PPS model can be used to assess the performance of any pool of executed projects, and introducing a novel addition to the field of construction business analytics which is a supplementary tool to successful decision making and performance improvement. Additionally, the bidding selection system can be revolutionized from a cost-based to a performance based one using the PPS model to improve the outcomes of the buyout process.

A Multi-Criteria Decision-Making Model for Selecting the Best Project Delivery Systems for Offsite Construction Projects

Off-site construction (OSC) is an innovative construction method that transfers most of the site-based work to a more controlled environment. Construction waste minimization, speedy schedules, higher sustainability, and better quality are some of the perceived benefits of OSC. Therefore, significant research attention has been given to OSC. However, minimal research attention has been given to procurement management in OSC, which could impact its pace of adoption. Existing studies on the procurement methods of OSC projects have overlooked several criteria related to OSC that impact the selection of the appropriate procurement methods (i.e., design-build, construction management, etc.). In addition, the literature lacks decision-making tools to assist OSC practitioners in selecting the appropriate procurement method. In this regard, this study contributes to the body of knowledge by (1) identifying the criteria that impact the selection of OSC procurement methods; (2) developing a multi-criteria decision-making (MCDM) model to select the appropriate OSC procurement methods. The developed MCDM model uses a hybrid approach of analytic network process (ANP) and evidential reasoning (ER). The ANP, which considers the interdependencies among the collected OSC procurement criteria, is used to calculate the relative importance weights through questionnaire surveys. The ER method evaluates various OSC procurement methods in accordance with the criteria importance weights. The results indicate that project quality, cost control, and funding arrangement are the prominent selection factors. On the other hand, the model reveals that the integrated project delivery (IPD) and construction management (CM) methods have the highest utility scores. The MCDM model has been validated by comparing the results with similar studies. The present study could assist OSC practitioners in selecting the appropriate procurement method for OSC projects.

Configuration Analysis of Integrated Project Delivery Principles’ Obstacle to Construction Project Level of Collaboration

Integrated Project Delivery (IPD) with collaborative work as its core is supported by increasing numbers of scholars and practitioners, due to the performance improvement of project construction and projects’ success promotion. However, some factors such as the contract, the technology, and the personnel behaviors hinder the application of IPD, which has negative impacts on the collaboration level of construction projects. On the basis of the configuration analysis, the purpose of this paper is to increase the effectiveness of collaborative management of construction projects by encouraging the application of IPD principles. This is achieved by introducing the proof of contradiction and thoroughly examining the impact of the application of IPD principles’ barrier with the level of collaboration. Added to that, the research necessity of configuration analysis on IPD principles’ obstacle to construction project collaboration is demonstrated through bibliometric analysis; thus, a questionnaire survey is applied to collect opinions related to IPD principles from 235 industry practitioners. Fuzzy set qualitative comparative analysis (fsQCA) is deployed to gather IPD principles’ obstacles for construction project collaboration. The results show that (1) the absence of contractual and behavioral principles obstructs significantly the level of collaboration of construction projects in several cases, (2) catalysts for IPD have no significant impact in most cases, and (3) the unfamiliarity with IPD has negative impacts on the application of its principles. The theoretical contribution consists of filling the gap in IPD’s collaborative management research and improving the research method in related fields. As for the practical contribution, it aims to prioritize the importance of IPD principles and provide valuable suggestions.

A Hybrid Multi-Criteria Decision Support System for Selecting the Most Sustainable Structural Material for a Multistory Building Construction

In recent years, the performance of the construction industry has highlighted the increased need for better resource efficiency, improved productivity, less waste, and increased value through sustainable construction practices. The core concept of sustainable construction is to maximize value and minimize harm by achieving a balance between social, economic, technical, and environmental aspects, commonly known as the pillars of sustainability. The decision regarding which structural material to select for any construction project is traditionally made based on technical and economic considerations with little or no attention paid to social and environmental aspects. Furthermore, the majority of the available literature on the subject considered three sustainability pillars (i.e., environmental, social, and economic), ignoring the influence of technical aspects for overall sustainability assessment. Industry experts have also noted an unfulfilled need for a multi-criteria decision-making (MCDM) technique that can integrate all stakeholders’ (project owner, designer, and constructor) opinions into the selection process. Hence, this research developed a decision support system (DSS) involving MCDM techniques to aid in selecting the most sustainable structural material, considering the four pillars of sustainability in the integrated project delivery (IPD) framework. A hybrid MCDM method combining AHP, TOPSIS, and VIKOR in a fuzzy environment was used to develop the DSS. A hypothetical eight-story building was considered for a case study to validate the developed DSS. The result shows that user preferences highly govern the final ranking of the alternative options of structural materials. Timber was chosen as the most sustainable option once the stakeholders assigned balanced importance to all factors of sustainable construction practices. The developed DSS was designed to be generic, can be used by any group of industry practitioners, and is expected to enhance objectivity and consistency of the decision-making process as a step towards achieving sustainable construction.

Liability Factors and Conceptual Framework for Contracts to Manage Design for Digital Fabrication in Construction Projects

The adoption of digital fabrication—fabrication based on digital design—in the early design phase in projects requires a thorough understanding of the liability factors to design the contract. This paper addresses this issue using a two-stage research approach. First, a case study research maps the process from digital design to digital fabrication in an existing project that adopted digital fabrication using the design-bid-build model. Second, a three-round Delphi survey of 14 stakeholders of that project identifies and ranks 163 liability factors under eight categories: actors, resources, conditions, attributes, processes, artifacts, values, and risks. The resources of management capability and building information modeling (BIM) expertise rank as the two most important liability factors. Building on these findings, the paper presents a conceptual framework for contract design and discusses how the existing project delivery models—design-bid-build, construction management, design-build, and integrated project delivery (IPD)—can consider the liability factors in contracts.

Optimum risk/reward sharing framework to incentivize integrated project delivery adoption

The major benefit of integrated project delivery (IPD) is the involvement of stakeholders at the early stage of the project so that they can all contribute to project development. They would also work cooperatively towards the project goals that they have jointly developed. Moreover, IPD has not taken the market as promised by the aforementioned benefits due to two principal concerns. First, the conventional risk/reward sharing that has been developed for the principal-agent type of relationship has been used. Second, the reward has not been tailored to reflect the stochastic nature of the risks involved. This study proposes a novel risk/reward sharing framework that would alleviate these two concerns. Employing stochastic cooperative game theory and prospect theory as conceptual lenses, a more realistic risk/reward sharing framework is developed for IPD projects. The use of Pareto optimality enables the proposed framework to arrange incentives optimally with due regard to the risk propensity of the contracting parties. Setting the notional sharing approach as a fair starting point, the framework further introduces transfer payments to ensure fairness and retain optimum sharing at the same time. Both features would facilitate the structuring of multi-win sharing incentive to be incorporated with integrated project delivery. The operation of the proposed framework is illustrated by applying it to a real case. Wider adoption of IPD can be expected when the two principal concerns of IPD arrangements are addressed.

Building Information Modelling, Integrated Project Delivery, and Lean Construction Maturity Attributes: A Delphi Study

The benefits of adopting collaborative approaches in the construction industry, such as Building Information Modelling (BIM), Integrated Project Delivery (IPD), and Lean Construction (LC), in an integrated manner are widely acknowledged in academia and industry. Once organizations have embraced BIM, IPD, and LC integration (BIL), a measurement method for evaluating their progress and planning for continuous improvement is required. However, there is no widely accepted capability assessment model, such as Maturity Models (MMs), to effectively assess productivity improvements in organizations adopting all three approaches based on the interdependencies between them. The first step in the process of BIL MM development is identifying the critical attributes of BIM, IPD, and LC integration. This research investigates the interrelationships of BIM, IPD, and LC for use in the maturity models, determining how BIM and IPD can support the application of LC principles. The mixed methods approach was adopted, and a literature review and a two-round Delphi survey were conducted for the data collection. The findings revealed a number of complementarities between BIM, IPD, and LC. The panel of experts agreed upon the five major attributes and 24 sub-attributes of BIM, IPD, and LC, which formed the structure of the presented integrated BIL framework. The significance of this study is to provide the basis for organizations that intend to implement BIM, IPD, and LC in an integrated manner. Interrelating these attributes in a maturity framework also supports the planning and evaluation of organizations’ progress towards realistic goals for continuous improvement.
