Key factors affecting project delivery system selection in the Chinese construction industry

This study aims to investigate the key factors owners consider when selecting a PDS, the importance degree of these factors, and the perception differences among owners, consultants, and contractors regarding these factors. Interviews and questionnaire surveys were used to determine the importance degree of each influencing factor. And perception differences of the influencing factors on PDS among the three subjects were calculated through SPSS 15.0. The findings show that the three subjects' perceptions of the importance degree of the economic attributes of the engineering project, engineering project complexity, sub-project construction interference degree, and delivery system preference were significantly different, while the perceptions of engineering project scale, investment control requirements, schedule requirements, quality requirements, risk preference, construction management capability, land acquisition, demolition and migration, construction site conditions, local policies and regulations, and construction market development level were insignificantly different. This research can help owners understand influencing factors on PDS selection from different dimensions. Valuable information was provided for owners to select an accurate and reasonable PDS, ultimately reducing project costs and facilitating project management. Additionally, this research complements previous research on PDS selection and proposes a new influencing factors framework by exploring the key factors affecting PDS selection and the perception differences between the three subjects.

Innovative strategic multicriteria decision-making selection model of infrastructures projects delivery systems using multiobjective optimization, case of Egypt

Purpose To help decision-makers choose appropriate infrastructure project delivery systems (IPDS) and keep up with the construction industry’s rapid growth, this study aims to develop a goal optimization technique.This looks into team integration, large production and optimum sustainability. The suggested approach for meeting several infrastructure project objectives is flexible and expandable. This research overcomes the significant discrepancy between the construction industry’s progress and the rate at which project delivery methods evolve. Design/methodology/approach This study examined pertinent literature to choose an appropriate project delivery method and gave information on several elements that affect that decision. After optimization using a genetic algorithm (GA), a Pareto front of solutions has been found. The three construction goals of sustainability, mass production and team integration are all met by the chosen best solution. The four most popular possibilities for studying the suggested approach are five primary categories, each of which has 22 variables, and the weight of each variable was established using Simo’s procedure. This is optimized, demonstrating the accuracy of the optimization model. Findings Sustainability, mass production and team integration are the major goals of selecting the finest IPDS. The Pareto-optimal solutions discovered through analysis demonstrated that the created GA is reliable and generates solid outcomes. In fact, it enables decisions that were based on a single criterion to be overturned. The process has therefore demonstrated its efficacy in identifying the ideal answer. First integrated project delivery (IPD), second design-build (DB), third design-bid-build (DBB) and last construction manager at risk (CMR) are the best options. The weight of the aims function has found these rankings to be satisfactory. Practical implications The findings demonstrate that the suggested strategy can lead to optimization, providing the government with a wide range of options for attaining certain project objectives. The ability of this study to evaluate the combined effects of three objectives in choosing the best IPDS, the production of optimal selection solutions (IPDS), which can help with better decision-making when many objectives are present, and the flexibility and extendibility of the suggested approach for achieving priorities in infrastructure projects are what make it unique. This approach was able to select IPDS to meet developments in the construction project. Originality/value To confirm the validity of the GA, the factor of error was calculated, which is equal to 1.7599e-08.

Matching of the Project Manager’s Approach and the Project Delivery System to Achieve Project Success in Yemeni Projects

The goal of this study is to seek answers to whether project managers’ approach is influenced by the project delivery system for achieving project success in Yemeni projects. A quantitative approach was adopted in this paper, and 375 project managers from two governorates of Yemen served as respondents. The idea is to assess the connection between the project managers’ approach (PMA) and the project delivery system (PDS). The results revealed that the project manager’s approach (participative and directive) and alignment with the project delivery systems (traditional or design and build) were directly linked with project success or failure. Moreover, the results revealed that the project managers adopting a participative approach have constructive effects, while the project managers adopting a directive approach harm project success. It is a chance for inexperienced project managers to receive advice on how to implement their management strategy and learn that, for Yemeni projects (YPs), every project delivery system requires a suitable approach to leadership.

Restoration manager: Adapting project delivery methods for the restoration of architectural heritage

The restoration of architectural heritage is a complex process and presents intricate and formidable challenges. The project delivery method plays a pivotal role for the success of the restoration process. There exists a diverse array of project delivery methods, each characterized by its distinct set of advantages and disadvantages. In the context of architectural heritage restoration, given its distinct characteristics, these advantages and disadvantages encompass a wide spectrum. Current project delivery methods, while effective for certain contexts, often fall short in addressing the unique requisites of restoration projects. Acknowledging this inadequacy, this article undertakes a research that includes a literature review that not only examines prevailing project delivery methods but also articulates the need for a tailored framework within the restoration field. This article is produced from the doctoral thesis titled "Development of a Sustainable Integrated Management System for the Conservation of Architectural Heritage", which is in the process of preparation. In the light of the results of the survey which is conducted within the scope of the first author's doctoral study in order to examine the project delivery approach preferred among the participants that are working in the field of the conservation of architectural heritage, a project delivery method called "Restoration Manager", which has been precisely prepared to meet the requirements inherent in restoration initiatives, is presented. This comprehensive project delivery method seeks to fill the void by addressing the distinct needs and challenges encountered in restoration projects. The essence of this work is to create an appropriate project delivery system that adapts to the nuances of the restoration works, and through this project delivery framework, the restoration processes and outcomes will successfully be completed.

Decision-Making for Project Delivery System in Construction Projects Based on SWARA-TOPSIS Methods

The owner of construction projects often faces difficulty choosing the appropriate project delivery system. The construction project’s owner must choose a suitable project delivery system throughout the project's early decision-making stages. This choice greatly impacts the success of the project. This paper aims to construct a method for project delivery decisions. This method can provide a reference for the owner to select the proper project delivery system. This research described the factors affecting the decision about the project delivery method through a literature review. These factors were categorized into eight groups: scope, time, quality, cost, risk and relationships, owner organization, project characteristics, and external environmental factors. Then, a combined methodology of Stepwise Weight Assessment Ratio Analysis (SWARA) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) are proposed for project delivery system selection. The SWARA is used to determine the factors’ weights. The TOPSIS technique determines the rank of the alternatives proposed for the delivery system in the various categories. The results showed the most significant factors related to the cost with a weight of 0.335, and the design-build is the closest to the ideal solution and ranked first among the other suggested project delivery systems with a relative closeness of 0.829. This paper stipulates the basis for such a process of decision-making.

Validating the Relative Importance of Technology Diffusion Barriers– Exploring Modular Construction Design-Build Practices in the UK

ABSTRACT This research investigates the low use of modular construction despite its recognized cost, time, quality, safety, and sustainability advantages. Using technology diffusion theory, this study seeks to identify and rank the characteristics that impede modular building adoption, such as relative advantage, compatibility, complexity, trialability, and observability. A survey of industry professionals in the United Kingdom was undertaken, and the results, validated by a one-sample t-test, showed that attitudes toward modular building, rather than technical difficulties, are the key impediments to broad adoption. The degree to which modular construction resonates with prospective adopters’ current values, past experiences, and requirements determines its acceptance. Traditional mind-sets, the presence of traditional constructs, resistance to change, prior attitudes, bid prices, hesitation, and skepticism are all associated with non-adoption. Professional positions serve as a bridge between adopters and non-adapters. The research also emphasizes the importance of design-build project delivery systems and early supplier chain participation in accelerating the mainstream adoption of modular construction.

Integrated project delivery (IPD) capabilities on reducing claims in urban underground projects: A hybrid FAHP-FTOPSIS approach

Participatory planning practices - associated with integrated project delivery (IPD) can influence the cost and time claims of construction projects. However, there is a lack of research providing a quantitative holistic assessment of implementing IPD practices for reducing claims. In order to fill this knowledge gap, the present study aims to present a hybrid prioritization model to assess and mitigate the impact of claims on urban underground projects using IPD capabilities. The fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS) methods are combined to prioritize traditional project delivery systems claims and rank IPD capabilities to reduce critical claims. FAHP identifies eight critical claims, including incorrect selection of the project contract system, lack of use of legal experts in setting contracts, exchange rate fluctuations and changes in currency conditions, lack of manpower skilled personnel in the region, ambiguities and shortcomings in the contract, restrictions on the supply of materials, machinery and equipment, delays in payments and financial obligations of the employer and lack of equipment and machinery appropriate to the type of work in the region. FTOPSIS ranks organizational and leadership, planning enhancement, and appropriate technology as the most effective capabilities in reducing claims. These capabilities should be implemented according to the obtained ranking to accept IPD in reducing the conventional claims future projects. The main innovation lies in the development of a hybrid prioritization framework to evaluate conventional contractual claims and rank IPD capabilities. The framework proposed in the study provides a valuable tool for construction managers to make informed decisions and mitigate the impact of contractual claims during the project delivery phase.

Analysis of integrated project delivery in the Irish Construction industry

The construction industry is complex and suffers from considerable challenges related to Project Delivery Systems (PDS) most notably cost overruns and delays. Integrated Project Delivery (IPD) has gained traction in recent years and is lauded to be an effective mechanism to overcome many of these challenges. However, implementing IPD in practice is not an easy endeavor, and there is a need to understand the motivation to adopt it as well as to understand the key challenges and critical success factors for its effective implementation. This exploratory study aims to address this deficit. We capture real-world data from professionals in the Irish construction industry to understand current practices and analyze the perceived challenges and critical success factors for the successful implementation of IPD. Our findings reveal a significant lack of awareness among participants regarding IPD and very low levels of implementation. Issues such as lack of trust, fear of litigation and reluctance to change are the major barriers to implementation. Critical success factors for successful implementation center on establishing integrated systems such as BIM and ensuring that information, process knowledge and organizational teams are integrated.

Critical Risk Factors of Stakeholder Collaboration Impacting BIM Implementation in High‐Rise Residential Building Projects Under the DBB System: A Delphi Survey

Although the design‐bid‐build (DBB) system has poor stakeholder collaboration due to the separation between architects, engineers, and contractors in its linear process, resulting in longer schedules and cost overruns, DBB remains the most widely used project delivery system due to its benefits, such as higher competition and the owner’s absolute control over the project. Researchers and practitioners expect building information modeling (BIM) implementation to improve stakeholder collaboration due to its potential to bridge the collaboration gap between these stakeholders, ensuring better coordination and motivating cost reduction. However, the fragmented nature of DBB still poses significant challenges to effective stakeholder collaboration, impacting BIM implementation negatively. Therefore, the objective of this study is to identify and rank critical risk factors (CRFs) related to stakeholder collaboration impacting BIM implementation in the context of high‐rise residential building projects delivered by DBB. By adopting a Delphi procedure, this study identified such CRFs by triangulating the knowledge from the literature and the experience of an expert panel recruited from the construction industry. Seven CRFs were selected and ranked through three rounds of a Delphi survey. Analysis revealed that the rankings remained unchanged despite the increasing degree of consensus among experts. The highest‐ranking negative CRFs were “Inappropriate mindset of BIM collaboration process,” “Awareness of additional roles and responsibilities,” and “Disconnection in the information flow and BIM process.” A matrix of nine recommended solutions that can be applied across different CRFs was collected from the expert panel to improve the productivity of BIM collaboration under DBB. This study provides an in‐depth understanding of the CRFs of BIM‐based collaboration between stakeholders under a nonintegrated delivery system like DBB. The findings of this study can ensure successful project completion by creating awareness and allowing professionals and researchers to develop practical strategies for delivering BIM‐based DBB projects.

Development of a Prediction System for Design Defects of Buildings

The research aimed to establish a quantitative model to predict the occurrence of five types of design defects: unsafe design, incompatible design, inefficient design, design ambiguity, and design delays. It also examined the contractor's liability for design to determine who is ultimately responsible for design defects disputes between the employer and contractor. The study employed a descriptive methodology to identify fifteen potential influencing factors on design defects. Data were collected from 42 construction projects and tested using Design of Experiments (DOE). Out of these fifteen factors, only five—design schedule, design firm experience, stakeholders’ involvement, project delivery system, and information accuracy—had a significant impact on design defects. These factors were used in the development of a new model to predict the occurrence of design defects. The model was validated using data that was held separate from the model development process for validation purposes. The calculated Mean Absolute Percentage of Error (MAPE) for the new model is 19%, which is considered a "good" prediction accuracy. The research achieved three significant milestones: 1) It identified the ultimate responsibility for the consequences of design defects in construction projects across different jurisdictions. This information can be used to resolve potential disputes between employers, designers, and contractors’ organizations. 2) It provided guidelines on how to minimize design defects in construction projects, thereby mitigating the consequences of such defects. 3) It developed a new model to predict the occurrence of design defects in construction projects. This model aids decision-makers in responsible organizations during the process of predicting the appropriate reserve to be added to the project schedule and budget. Consequently, it helps mitigate the risk of design defect-related delays and cost overruns. Doi: 10.28991/CEJ-SP2023-09-017 Full Text: PDF

A Method of Selecting Project Delivery System with Pythagorean Fuzzy Set Group Decision-Making Method and Prospect Theory

Project delivery system (PDS) is critical to the success of a construction project. There is a strong link between contract type and project delivery method. Therefore, this paper presents a framework for multiobjective decision-making that combines project delivery method and contract type for the first time. Furthermore, the Pythagorean fuzzy set (PFS) is introduced in the decision-making model. A new method for PDS group decision-making is constructed by combining PFS with the entropy weighting method and prospect theory. In order to improve the reliability of decision-making, this paper proposes a new method for determining decision-maker weights based on comprehensive weights, which is used to distinguish the professional level of decision-makers. Finally, the PDS decision-making process is elaborated through case analysis, the effectiveness of the decision-making model is verified, and the differences between the PDS decision-making method and the traditional method are discussed, which proves the reliability of the method. The method proposed in this paper can provide support for the owner’s PDS selection.

Integration mechanisms for material suppliers in the construction supply chain: a systematic literature review

The construction industry has long been criticized for its fragmented, inefficient, and uncoordinated supply chain. Thus, construction companies are actively looking for new strategies to overcome these issues and to improve their productivity. Supply chain integration is one strategy and many articles have addressed the mechanisms to help integrate the construction supply chain. However, little interest has been paid to material supplier integration despite their important role and their vast experience in the market. Hence, this study aims to identify the mechanisms that could contribute to facilitate material supplier integration in the construction supply chain. A systematic literature review was conducted to uncover the studies on this topic. A total of 310 articles were reviewed and analyzed to first reveal six integration mechanism categories: supplier qualification, supplier development program, contractual and relational policies, information sharing and integration systems, joint team working and problem solving, as well as supplier integration evaluation. Secondly, this study proposes a roadmap to illustrate when these mechanisms should be implemented in a construction project, according to both the project phases and the project delivery system. Finally, research gaps in the field are identified as well as future research directions that could be further explored by researchers and professionals.

Comparison Study between Iraqi Conditions of Contract and FIDIC Conditions- The Red Book

Reconstruction in Iraq requires coherent legitimate frameworks that are able to detail obligations, rights and responsibilities of the parties participating in reconstruction projects, regardless their type or delivery system.Conditions of Contract can be considered an important component of these frameworks. This paper investigates flexibility and appropriateness of the application of Iraqi conditions of contract in reconstruction projects. These conditions were compared to FIDIC Conditions. The objective wasn't comparing individual clauses, but rather exploring the principles and philosophy laying behind each conditions, and to what extent each conditions care about realizing equity between main contract parties. Validity of application on various project delivery systems was also investigated. The structure of Iraqi and FIDIC conditions were compared to determine how the efficiency of use will be effected by the layout, presentation, organization, and detailing of the contents of each conditions. Moreover, some clauses related to the project parties were compared in order to further illustrate the disparity in efficiency of each conditions. The paper concludes that Iraqi conditions of contract in its current state was, and will continue, hindering the reconstruction efforts in Iraq, as well as being a cause of money waste and bad quality of project outputs.

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.

A conceptual framework for integrating QSHE in construction

Construction accidents become catastrophic in infrastructure development. Evidence shows that quality failures such as system, services, procedural, materials, equipment, and human failures within the business process of project delivery systems are contributing causes of construction accidents that negatively impact worker safety, public safety, building/asset, and environmental safety. The standardized quality management systems and safety management systems in construction are fragmented. The Indonesian authorities have integrated the Quality Safety Health and Environment (QSHE) management system since 2018, but the implementation of the integrated QSHE system is still questionable. This paper aims to propose a framework and methodology for integrating QSHE implementation. The framework is based on the literature review of international standards and the UK Construction Design & Management Regulation. This proposal is a part of research currently formulated to develop an operating system to integrate quality and construction safety best practices in the project delivery systems. This paper addresses the quality management framework, safety management framework and, the proposed conceptual framework for integrating quality and safety management systems. The development of an integrated QSHE management system has the potential to save resources and eliminate redundancy significantly. Thus, an organization’s net production, profitability, and efficiency can significantly be increased. The results of this paper are 51 key points that are needed for integrating QSHE in construction projects. In the pre-construction stage, there are 24 key points, which are the largest portion. During the construction stage, there are 19 key points, and during the post-construction stage, there are 8 key points. So, it is very important to carry out the QSHE integration during the pre-construction stage to minimize the defects and accidents in construction projects.

Blockchain Technology toward Smart Construction: Review and Future Directions

The construction industry has been criticized for low productivity, lack of collaboration and information sharing, poor contract administration, and the like due to its decentralized and fragmented structure as well as sequential and chain-resembling nature. Recently, blockchain technology and its benefits have received wide attention and interest. This research synthesizes the research trends and needs of this growing area by means of a bibliometric-qualitative review method. Scopus and Web of Science were selected as the literature databases to retrieve relevant academic publications. Through a systematic literature search and screening, 181 related articles were identified for bibliometric analysis, and 149 publications were critically discussed in a qualitative review. The bibliometric results indicated the recent research regarding blockchain in construction is primarily directed into several clusters, such as “smart contract,” “Building Information Modeling (BIM),” “supply chain management,” “construction contract,” “construction and project management,” “digital twin,” and “smart city.” These clusters were further synthesized for a qualitative review revealing deep insight into research challenges and gaps. Both quantitative and qualitative review results were then mapped to the future directions. It was noted that future research needs to focus on (1) quantifying the cost-benefits of the blockchain applications in construction, e.g., return on investment, practitioners training, and improving industry readiness, (2) integration of blockchain with different project delivery systems, and (3) technology fusion with blockchain for construction management.

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.
