The Architecture, Engineering, and Construction (AEC) industry is plagued by persistent challenges such as low productivity, cost overruns, and frequent project delays. Integrated Project Delivery (IPD) has emerged as a potential solution, offering collaborative approaches to improve project outcomes. This study proposes a two-tiered methodology for evaluating the disruptiveness of innovations in the AEC industry, with a particular focus on IPD as a disruptive innovation. In the first tier, a multidimensional framework is developed to systematically assess the disruptiveness of innovations in the AEC sector. This framework, informed by a thorough literature review and disruptive innovation theory, includes dimensions such as business models, processes, and anticipated outcomes. The second tier applies the framework by analyzing the disruptiveness of IPD. The assessment draws on data from three comprehensive studies, including ethnographic research, interviews, and focus groups, which examine IPD’s impact on different stakeholder groups such as clients, consultants, and contractors. Findings reveal that IPD has the potential to significantly disrupt traditional business models, processes, and project outcomes, particularly at the project level. Notable disruptive characteristics include shifts in collaboration dynamics, redefined project financing models, and improved efficiency. However, several barriers hinder IPD adoption, including resistance to change and misalignment with conventional contractual structures. Expert interviews support these results, indicating that IPD represents a fundamental shift in the AEC industry. This research contributes to the existing body of knowledge by offering a structured framework for assessing the disruptiveness of AEC innovations and demonstrating its practical application. In this way, AEC organizations, projects, and practitioners can better strategize for the adoption of any new disruptive innovation and thus pursue a strategic advantage in the highly competitive industry market.

As the adoption of integrated project delivery (IPD) progresses, increasing evidence has highlighted its potential to improve project outcomes. However, as an emerging practice, there remains a lack of structured mechanisms to evaluate the maturity of its implementation, which can limit opportunities for learning and improvement. Therefore, this study introduces an IPD Capability Maturity Model (IPDCMM) to evaluate the maturity of IPD implementation at the project level. This model enables organizations to benchmark their IPD capabilities against established best practices, facilitating structured development and continuous improvement. This model is designed as a post-project assessment tool that evaluates the maturity of IPD practice upon project completion, providing critical insights for learning and future project enhancements. The methodology, underpinned by a pragmatic philosophy and guided by the principles of design science research (DSR), prioritizes achieving practical outcomes (artifact). It combines insights from IPD frameworks, maturity models from other fields, and three case studies. The IPDCMM was developed alongside the IPD Maturity Assessment Tool (IPD-MAT), an artifact validated via evaluation sessions and feedback interviews with key stakeholders of IPD case studies. This model provides a structured framework for assessing IPD implementation maturity and facilitates a pathway for enhancing IPD practices and achieving efficiency in project delivery. Full article

Construction projects often exceed budgets and deadlines, evidencing the need for collaborative methodologies such as Integrated Project Delivery (IPD) and Building Information Modeling (BIM). This research evaluates their influence on the design stage of residential buildings through a case study in Peru, managed by an SME. The methodology includes: (1) diagnosis of management through documentary review and interviews, (2) proposal of tools based on BIM and IPD, and (3) validation through statistical analysis and a validation matrix. Nine typical problems were identified, such as deficiencies in plans, measurements and budgets, and poor planning. Eight optimization tools were proposed, including NEC4 ECC contracts, Trimble Connect, Revit, Navis-works, contractor integration, ICE Sessions, 3D, 4D, and 5D BIM models. The 3D model showed 0.48 interferences per m², the 4D facilitated the monitoring of progress, and the 5D optimized costs by 5.28%. The validation process highlighted the NEC4 ECC Contract, the integration of the contractor, and the 3D and 5D BIM models (Revit and Navisworks) as the most effective tools. This study provides evidence on the implementation of BIM and IPD to optimize the management of residential buildings. Full article

In the current context of transformation within the Architecture, Engineering, and Construction (AEC) sector, and the growing adoption of interdisciplinary collaboration processes such as Integrated Project Delivery (IPD) and Building Information Modeling (BIM), information management systems are crucial to ensure both the security and reliability of data, and its effective distribution among project stakeholders. Collaborative centralized information systems have emerged as powerful tools for communication and data exchange. However, establishing efficient and flexible methodologies for managing this information remains a significant challenge. This study aims to demonstrate the effectiveness of collaborative centralized information systems in project information management through a real-world example. The research focuses on analyzing a pilot project developed by our organization using the Bimcollab digital collaborative platform. The methodology adopted includes the following: (i) descriptive characterization of the project; (ii) selection of a defined timeframe; (iii) description and characterization of the information management systems; and (iv) comparative analysis between non-centralized and centralized information management systems. The case study examines the Detail Design phase of a project for a pharmaceutical industry complex comprising six buildings, with a total area of approximately 18,000 m². From October to December 2022, a non-centralized information system was used, followed by the implementation of a centralized information system from January to March 2023. Key indicators, such as the number of occurrences, average number of recipients involved, response times, and resolution rates, were analyzed. The results showed that the complete resolution rate improved from 51% under the non-centralized system to 85% with the centralized system, representing a 34% increase. The pilot project underscores the benefits of centralized collaborative information systems, particularly in reducing response times and increasing resolution rates among stakeholders. These benefits are expected to apply across various functional programs, including residential construction, contributing to optimizing both project design and construction practices. While derived from a single case study, the findings highlight the need for further research involving multiple cases and phases of the project lifecycle to validate the generalizability of these outcomes.

The construction industry faces persistent inefficiencies, with projects often failing to meet time, cost, quality, and other conditions of satisfaction. This study investigated real estate owners’ early perceptions of Lean Integrated Project Delivery (Lean IPD) as a potential solution, analyzing the acceptance of principles such as early stakeholder involvement, risk–reward compensation, and open-book accounting, among other key features in Lean IPD. A survey of 62 professionals in real estate development companies in Spain was conducted, analyzing their experience with collaborative contracts and Lean techniques, including Last Planner System and Target Value Design. Statistical methods such as hierarchical clustering and PLS-SEM modeling revealed two distinct groups: those receptive to Lean IPD’s economic mechanisms and those less inclined. While governance principles like early collaboration and team co-responsibility received widespread support, skepticism was noted toward economic transparency practices due to cultural and structural barriers. Additionally, the findings indicate a significant gap in formal training for Lean IPD. Despite challenges, there is strong interest in adopting Lean IPD, driven by its potential to address critical project inefficiencies. This study concludes that successful Lean IPD implementation requires strategic leadership from owners, targeted training programs, and a cultural shift within the industry to embrace collaborative and transparent practices.

Building information modelling (BIM) is an appreciated technology in the field of architecture and construction management. Collaboration of information in BIM has not been fully utilized in the structural engineering stream as many engineers keep on working with previous prevailing design approaches. Failure to adequately facilitate automation in design could lead to structural defects, construction rework, or even structural clashes, with major financial implications. Given the inherent complexity of large-scale construction projects, the ‘manual design and detailing’ of structure is a challenging task and prone to human errors. Against this backdrop, this study developed a 4D building information management approach to facilitate automated structural models for professionals designing all the elements required in reinforced concrete (RC) structures like slabs, beams, and columns. The main contribution of this study is to obtain structural models directly from architecture models automatically, which reduces effort and possible errors in the previous prevailing approaches. The framework enables execution of all the model design works automatically through coding. This is achieved by executing a script which is beneficial for integrated project delivery (IPD). The 3D structural model in BIM software presented in this study extracts and transfers the geometrical data and links these data in Industry Foundation Classes (IFC) files using integration facilitated by Python 3.6 and IFCopenshell. The developed automated programme framework offers a cost-effective and accurate methodology to address the limitations and inefficiencies of traditional methods of structural modelling, which had been carried out manually. The authors have developed a novel tool to extract structural models from architectural models without proprietary software, greatly benefiting BIM managers by enhancing 3D BIM models. This advancement toward Open BIM, crucial for the architecture, engineering, and construction (AEC) industry’s future, is accessible to educators and beginners and highlights BIM’s effectiveness in improving structural analysis and productivity. The core finding of this study is to generate a structural model from an architecture model by automating the script with Python integration of IFC and IFCopenshell. The merits of the developed framework are reduced clashes, more economical structural modelling, and fully automated smart work as functions of the IPD. Full article

With the emerging large- and medium-sized engineering projects, prominent project delivery methods make sense in terms of cost, risk, management, and schedule. Among these, the Integrated Project Delivery (IPD) method stands out due to its adaptability for growing scale and complexity projects. This study compares the IPD method with other methods, emphasizing its benefits in large- and medium-sized projects and introducing the Fuzzy Analytic Hierarchy Process (FAHP) model to analyze IPD’s adaptability quantitatively. By conducting a matrix calculation of eighteen second-level indicators, this study derived weight values for four first-level indicators: Cost control, Risk control, Management control, and Schedule control. These first-level indicators were then used to formulate the total evaluation index calculation. Based on this foundation, we verified the calculations using a case study in Fujian. Implementing the IPD method led to a lower cost than the Owner’s Representative method and a one-year schedule acceleration. The FAHP model introduced in this study offers a novel and objective approach for adaptability analysis of the IPD method in large- and medium-sized engineering projects, coupling decision theory into project management.

Integrated project delivery (IPD) has gained significant attention as an effective alternative to traditional project delivery models. Profit distribution is a crucial aspect of IPD projects, influencing their overall success. This study aims to investigate the key factors impacting profit distribution to offer strategic guidance for project management practices. The study employs a comprehensive bibliometric analysis to establish an updated research framework in this domain. Through this analysis, 24 articles with highly relevant and extensively cited sources are identified for further examination. Grounded theory is subsequently applied to distill the findings. This process yields a foundational theoretical framework that delineates the factors influencing profit distribution in IPD projects, namely, contribution, resource-based input, effort level, and risk sharing. Additionally, a textual analysis of ten burst words is conducted to discern research trends and identify future areas of study. This research contributes to the existing literature by addressing gaps and providing a roadmap for future IPD investigations. A theoretical framework of influencing factors in profit distribution in IPD projects is developed based on the literature. The findings not only enhance understanding of profit distribution dynamics in IPD projects but also guide the implementation and optimization of IPD practices. Full article

The integration of building information modeling (BIM) and the integrated project delivery (IPD) mode effectively promotes collaboration among project members and enhances project profitability. However, the issue of profit sharing significantly impacts the successful implementation of IPD projects. To enhance the profit-sharing mechanism of IPD projects and ensure their smooth implementation, a game analysis model of profit sharing in IPD projects was established based on the Stackelberg game theory, taking into account the multidimensional fair preferences of the participants and the application of BIM technology. Through simulation, the impact of various parameters of participants on output utility, total revenue, and sharing coefficient in IPD projects was analyzed. The results show that: (1) participants achieve their highest output utility and total revenue under vertical–horizontal fairness preferences; (2) under vertical fairness preferences, the profit sharing coefficient is the highest, while the output utility and total revenue are the lowest; (3) although the output utility and total revenue of participants under horizontal fairness preferences exceed those under neutral fairness preferences, the profit-sharing coefficient is lower; (4) the output utility, the total revenue, and the profit-sharing coefficient of the participants all increase with the increase in effort utility value and decrease with the increase in the effort cost coefficient and the risk avoidance coefficient. The research findings provide valuable theoretical support for the profit sharing of IPD projects, thereby further promoting the advancement and implementation of the IPD model. Full article

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. Full article

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.

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. Full article

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.

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. Full article
