Sewer pipeline failures pose significant threats to the environment and public health. To tackle these repercussions, many deterioration models have been developed to predict the conditions of sewer pipes, most of which are based on CCTV inspection reports. However, these reports are prone to errors due to their subjective nature and human involvement. More importantly, there are insufficient data to develop prudent deterioration models. To address these shortcomings, this paper aims to develop a CCTV-based deterioration model for sewer pipes using Artificial Intelligence (AI). The AI-based model relies on the integration of an unsupervised, multilinear regression technique and Weibull analysis. Findings derived from the Weibull deterioration curve indicate that the useful service life for concrete and vitrified clay pipes are 79 years and 48 years, respectively. The regression models show that the R2 value for vitrified clay sewer pipes, concrete sewer pipes, and ductile iron sewer pipes are 71.18%, 71.47%, and 81.51%, respectively, and 73.69% for concrete stormwater pipes. To illustrate the impact of various factors on sewer pipes, sensitivity analyses under different scenarios are conducted. These analyses indicate that pipe diameter has a significant influence on sewer pipe deterioration, with little impact on stormwater pipes. These findings would guide decision makers in identifying critical pipes and taking necessary precautionary measures. Further, this provides a sound basis for prioritizing maintenance actions, which would pave the way for designing sustainable urban drainage systems for cities.

The concepts of sustainability should be incorporated at every level of the decision-making process during the construction of residential building projects. It will ensure maximum cost savings without compromising the residential buildings’ services. To understand these sustainability principles, this study was conducted to identify and investigate the critical success factors (CSFs) required for implementing cyber technology in residential building projects. These CSFs were obtained from existing studies that were contextually explored via a questionnaire survey involving construction experts in the Nigerian building industry. Based on the Exploratory Factor Analysis (EFA) results, cyber technology CSFs were grouped into five distinct constructs: Governmental, Customer satisfaction, Time, Social safety, and Marketability of the construction product. Partial Least Square Structural Equation Modeling (PLS-SEM) was adopted to develop the model for the CSFs. The study showed that the Governmental component possessed the highest effect on the model, further underlining this construct as a crucial CSF in implementing cyber/digital technology. The findings from this study will facilitate cyber/digital technology introduction in the Nigerian construction industry. It will aid decision-makers and construction professionals in seeking viable ways of reducing costs and improving sustainability. Thus, this study has developed a CSF model to showcase the adoption of cyber/digital technology, with other implications for facilitating the goal of achieving sustainable residential building projects.

Purpose To realize full benefits without sacrificing the practicality of such projects, the decision-making process for residential building construction needs to include sustainability principles at every level. Therefore, this paper aims to investigate the applicability of radio frequency identification (RFID) and identify the barriers that impede its successful adoption in construction projects to achieve sustainability. Design/methodology/approach This paper opted for a quantitative approach by using a structured questionnaire survey. A total of 107 responses were collected from Nigerian construction practitioners involved in private and public construction businesses. Findings The results showed the high cost of RFID implementation, with a mean score of 4.42 as the top-ranked barrier, followed by lack of security, maintenance, power availability and inadequate training. This study further deployed Ginni’s mean difference measure of dispersion and revealed that the stationary barrier to adopting RFID technology is the lack of demand. Practical implications The findings of this research can assist decision-makers in improving the sustainability of all building projects by implementing RFID. Originality/value The findings of this study will serve as the basis for comprehension and critically evaluate the numerous barriers preventing the widespread adoption of RFID technology.

One of an organization’s significant challenges in a globalized world is reducing risk by building resilient supply chains (SCs). It is required to realize a competitive advantage in a volatile and fast changing environment. Conversely, the key enablers of such sustainable and resilient supply chain management are not fully analyzed in building projects. This study aims at determining the stationary enablers of resilient and sustainable supply chains. For this to happen, a questionnaire survey comprising 32 enablers of resilient and sustainable supply chains has been conducted with Egyptian engineers to appraise their degree of importance. The results show that the five most important enablers of resilient and sustainable supply chains are: top management support, adaptability, visibility, quality awareness, and responsiveness. This research’s results will allow building administrators to create diverse SCs, while being mindful of how the characteristics of a supply chain decrease or increase its resilience and eventually affect the exposure to risk in the building’s SCs.

Sustainability principles need to be applied at all the stages of the decision-making process concerning the building of urban housing to realize maximum benefits without compromising the project’s function. This paper aims to investigate the applicability of radio frequency identification (RFID) and identify the barriers that impede its successful adoption in building projects to achieve sustainability in building. The literature was reviewed, and data were derived by complementing the quantitative technique. A questionnaire was employed to gather data from 107 stakeholders in the building industry in Nigeria. The data were scrutinized using the exploratory factor analysis (EFA) technique. The partial least square structural equation modeling (PLS-SEM) was also applied to create a model for embracing RFID tools for sustainable building. The results of EFA revealed that the RFID barriers could be classified into significant constructs: infrastructure, immaturity, privacy, and security. The PLS-SEM model revealed that infrastructure was the most significant barrier to RFID implementation in the building industry. Thus, this study’s findings could aid decision makers in facilitating sustainability approaches in buildings projects through RFID implementation. These results would further lay the basis for objectively measuring and valuing the diverse barriers impacting RFID implementation.

Purpose The purpose of this paper is to examine the relationship between overcoming the value management (VM) implementation barriers and VM implementation in the Egyptian building sector. Design/methodology/approach A critical review of the literature on VM was used to through bibliometric analysis has been conducted to highlight the studies’ gap and establish the VM barriers. These obstacles were then contextually transformed via a semi-structured interview and a pilot study, and subsequently organized in the form of a theoretical model. The primary data was collected from 335 building stakeholders in Egypt through the administration of questionnaire surveys. Consequently, structural equation models of partial least squares were applied to statistically assess the final model of VM barriers. Findings The bibliometric analysis shows that there is an inadequate study on VM implementation barriers in the Egyptian construction industry and insufficient studies on implementing VM in developing countries. Results obtained from the proposed model showed that overcoming the VM barriers has a major connection with successful VM implementation. This is indicated with the value of ß = 0.743, which is necessary when the firm is overcoming 1 unit of VM barriers. Originality/value This study fills the knowledge gap by identifying and emphasizing the critical obstacles to VM implementation.

This study aims to evaluate the value management (VM) implementation barriers in construction projects. Consequently, information from 126 experts in the building industry was gathered via a questionnaire survey. Subsequently, the data were analyzed by exploratory factor analysis (EFA) and partial least square structural modeling (PLS-SEM). The results of EFA revealed that the VM barriers were grouped into six new constructs: client, knowledge, information, culture, resources, team members, and workshop. The barriers prioritization model was developed using PLS-SEM, and it indicated that team members are critical barriers to VM adoption. Although this study was limited to India’s VM context, its findings can be applied to other developing countries yet to implement VM in their construction industries. The study enhances stakeholder awareness and an understanding of the barriers affecting the implementation of VM, including building professionals, in India. It suggests strategies and activities overcome these barriers and facilitate a higher building quality, while maintaining a reasonable price. Refereed/Peer-reviewed

During the past two decades, value management (VM), has developed into a recognized construction practice. However, the methods and activities associated with VM adopt informal approaches in developing countries. This study aims to explore the critical success factors (CSFs) of VM implementation. Consequently, VM CSFs were investigated from the previous literature and further categorized over a semi-structured interview. The importance of these CSFs investigated by 335 structured questionnaires completed by residential building professionals. Subsequently, the exploratory study using the exploratory Pearson correlation of the VM CSFs was employed to validate the categorization resulting from a semi-structured interview and pilot study phases. Based on the validation results, the VM CSFs may be divided into four dimensions: culture and environment, workshop dynamics, stakeholder and knowledge, and standardization. Through important relative index (RII) analysis, the essential CSFs creates a VM team from a variety of disciplines, VM knowledge, experience of participants, and professional experience of the different participants’ diverse disciplines. In addition, this research used a stationary analytic strategy to evaluate the degree to which VM critical success factors (CSFs) have been incorporated into residential construction projects in Egypt. The results revealed that “establishing the roles and purposes of various professions” was the stationary success factor for adopting VM. This research establishes a road map for successful VM implementation via VM CSFs in Egypt and other underdeveloped nations. Stakeholders in the residential construction sector would benefit from this study by learning more about VM CSFs and how they may be used to increase the value of their projects.

Building Information Modelling (BIM) has not been sufficiently proliferated in the developing construction communities. This is owing to the lack of incorporating the key success factors (KSFs) of BIM implementation in a phase-based roadmap to support implementing BIM in practice on a step-by-step approach. With this in mind, this work aims at (1) defining the KSFs for implementing BIM within the developing economies’ socio-economic environment, (2) investigating the interrelationships among the KSFs, and (3) establishing the KSFs in a phased approach to devise a roadmap for their implementation on a step-by-step basis. First, 18 KSFs for implementing BIM have been specified by systematically investigating the pertinent literature and interviewing six well-qualified practitioners in BIM from Egypt, as a developing country. Second, from ten Egyptian BIM experts, data on the influences of the KSFs on each other have been gathered, employing a matrix format-based questionnaire. Third, the experts’ evaluations have been processed, utilizing the Decision-Making Trial and Evaluation Laboratory (DEMATEL) technique. Proficiently, DEMATEL through its causal diagram portrayed the cause-and-effect relations map of the KSFs. Besides, it divided the KSFs into four clusters, each of which signifies a phase in the BIM implementation journey along with its corresponding priority as well as the priorities of the KSFs that it encompasses. The causal diagram indicated that phase one related KSFs of the BIM implementation journey: research and development investments, senior management support, and firm’s fiscal support contribute to the whole success of the developed BIM implementation roadmap. This study equips construction practitioners in the developing economies with a four-phased roadmap for applying the KSFs of BIM implementation journey in practice on a step-by-step basis. This contribution helps in better prioritizing their decisions and optimizing the allocation of their resources when applying BIM in their business. Hence, at a fast pace, BIM can be proliferated in those countries.

Recent years have seen a rise in the frequency and severity of extreme rainstorm events, which have caused widespread damage and death in numerous cities. The manufacture and use of storm drainage materials result in numerous environmental concerns in the construction industry. Green materials for storm drainage networks are environmentally friendly compared to their traditional counterparts. Identifying and assessing sustainability criteria for green materials for storm drain networks has been challenging. This study aims to determine the critical criteria for selecting green materials for storm drainage networks using a stationary analysis approach. To this end, a questionnaire survey was administered to Egyptian storm engineers to assess their importance based on a selection criteria 29 green materials. From the results obtained, “Operation and maintenance cost” and “Use of local material” were seen to be the “stationary materials”. The obtained findings in this research pave the way for the Egyptian storm industry towards becoming environmentally friendly, which will in turn improve the functioning mechanism of sewer networks.

To reap the most advantages while maintaining the functioning of residential building projects, sustainability concepts should be included at all stages of the construction decision-making process. This research identified and investigated the barriers to the employment of cyber technology in residential construction projects in order to ensure their long-term viability. Prior research identified cyber technology barriers, which were then contextually explored using a questionnaire survey in the Nigerian construction business. An exploratory factor analysis (EFA) revealed that cyber technology hurdles may be classified into five constructs: knowledge, government, culture, project nature, and regulations. The barriers model was also built using partial least square structural equation modelling (PLS-SEM). According to the findings, project-related constraints were key impediments to the implementation of cyber technology. The findings of this study might serve as a guide for decision-makers in Nigeria’s construction industry looking to decrease costs and boost sustainability via the use of cyber technology.

Although sustainability has been an issue in the built environment for some time, it has not yet been fully addressed in sustainable interior architecture and design. This research aimed to identify and analyze obstacles preventing sustainable interior architecture and design implementation. As a result, the partial least structural equation modeling approach (PLS-SEM) has been requested to evaluate these obstructions. Therefore, after identifying 30 possible barriers through a literature search, a survey questionnaire was issued to 100 interior designers to evaluate their significance. According to the findings, governmental obstacles are the most pressing, followed by those related to information, knowledge, awareness, technology, training, attitudes, the market, and economics. This study’s conclusions may benefit professional interior architects, designers, academics, statutory authorities, administrations, and politicians. The current study addresses the lack of prior literature by compiling a thorough inventory of obstacles to environmentally friendly interior architecture and design, lays the framework for more in-depth future studies, and uses a unique PLS-SEM that has not been used previously.

Most elderly people have difficulty opening a new bottle cap due to the insufficient torque to be applied. The study aims at obtaining normative data on the hand dimensions and the maximum torque that could be generated by elderly persons. This study was conducted on 30 elderly people aged 60 and over. A digital torque meter, digital caliper, and tissue tape were used to measure the maximum torque on a dummy bottle and hand dimensions. SPSS software was used for all statistical analyses. Older men have been found to have larger hand dimensions than older women. However, no significant differences in hand dimensions were found between different age groups. A statistically significant difference was observed between the age group 60–69 years vs. 80–89 years and the age group 70–79 years vs. 80–89 years in maximum torque. The correlation between hand dimensions (thumb width and index finger length) and maximum torque was highly correlated (r = 0.63 and r = 0.62, respectively). Knowledge of the relationship between hand dimensions and maximum torque can be used for future bottle cap designs to meet the needs of the elderly.

Sustainability principles should be implemented during all the phases of the decision-making process of constructing residential buildings to achieve maximum gains without compromising the function of such projects. This study identified and examined the benefits of implementing cyber technology in residential building projects, with a view to promoting the sustainability of such projects. The benefits of cyber technology were identified from previous studies, which were then contextually explored via survey questionnaires within the Nigerian building industry. The results from the exploratory factor analysis (EFA) technique showed that the cyber technology benefits could be categorized into five constructs, namely, planning, transparency, efficiency, productivity, and quality. In addition, partial least square structural equation modelling (PLS-SEM) was used to develop the benefits model. The results showed that transparency related benefits were crucial benefits for implementing cyber technology. The study’s results will serve as a reference for decision-makers looking to decrease costs and increase sustainability by using cyber technology in the Nigerian construction sector.

To maximize the benefits without sacrificing the functionality of projects, sustainability concepts should be used across all stages of the decision-making process when creating residential buildings. The primary sustainable aims may be improved with BIM activities. However, in the building sector of underdeveloped nations, BIM activities use informal methods. By examining the connection between overcoming BIM implementation challenges and the overall sustainable success (OSS) in building projects, this research seeks to establish a model for BIM implementation. Following the BIM hurdles identified in earlier research, 86 building stakeholders in the Egyptian building sector were given questionnaires. The structure of the obstacles was established and confirmed using partial least-squares structural equation modeling (PLS-SEM), and the connections between the OSS and overcoming BIM deployment were investigated. The adoption of BIM contributed 40.7% to the project’s long-term sustainability, according to the data, which demonstrated a strong link. The findings of this research will serve as a roadmap for decision-makers who want to use BIM in developing nations’ building sectors to save costs and increase sustainability.

Purpose The purpose of this paper is to investigate the applicability of cloud computing (CC) and the challenges that contribute to more successful projects with a major sustainable construction development. Design/methodology/approach The previous studies provided information on CC implementation barriers, which were then evaluated by 104 construction stakeholders through a questionnaire survey. As a result, the exploratory factor analysis (EFA) approach was used to investigate these barriers. Furthermore, a partial least square structural equation model was used to build a model of these barriers (PLS-SEM). Findings The EFA results revealed that the above-noted factors are in a close relation with three key components, i.e. social, economic and communication. In addition, the proposed model results found the social barrier a key challenge to the implementation of CC. Research limitations/implications The results from this study can help decision-makers to improve the approaches regarding data fragmentation that has great effects on the execution of all construction projects. The focus of the paper is to enhance the data fragmentation processes. In addition, the results would be useful to strengthen the sustainability of existing construction projects by enhancing the implementation of CC. Originality/value The novelty of this research work will provide a solid foundation for critically assessing and appreciating the different barriers affecting the adoption of CC.

Purpose The purpose of this paper is to evaluate the barriers militating against the adoption of robotics in the construction industry. Design/methodology/approach Robotics implementation barriers were obtained from the previous studies and then through questionnaire survey construction stakeholders in Nigeria evaluate these barriers. Consequently, these barriers were examined via the exploratory factor analysis (EFA) technique. Furthermore, a model of these barriers was implemented by means of a partial least square structural equation modeling (PLS-SEM). Findings The EFA results showed that these barriers could be categorized into two: cost and technology. Results obtained from the proposed model showed that platform tools were crucial tools for implementing cloud computing. Originality/value The novelty of this research work will be provided a solid foundation for critically assessing and appreciating the different barriers affecting the adoption of robotics.

Sustainability concepts should be adopted via new technologies to achieve the greatest possible gains without compromising the objectives of projects. In this research, we empirically investigated the influence of identified drivers on the implementation of robotics in the building sector of developing countries. To this end, with a view to sustainable building projects, the drivers of robotics were derived from the literature, which were subsequently contextually adjusted using a survey method through the exploratory factor analysis (EFA) method. The results of EFA revealed that the drivers of robotics can be classified into three primary constructs: technology, industry, and culture. However, the benefits of implementing robotics can be grouped into two primary constructs: resources and environment. Therefore, in this study, we employed partial least squares structural equation modeling (PLS-SEM) to evaluate the connections amongst drivers and applications of robotics in Nigeria’s building industry. The results indicated that the input to the implementation of robotics in Nigeria’s building industry via the drivers of robotics has a considerable influence at a small scale, with an impact of 14.5%. The findings of this study can serve as a guide for policymakers looking to improve their projects and increase sustainability by using robotics in the building sector.

The advent of digitalization has brought many benefits to all sectors of the economy, including construction. When fully implemented, various Fourth Industrial Revolution (4IR) tools have the potential not only to improve project planning and execution, but also to enhance project performance. This study therefore investigated the critical factors for the adoption of 4IR technologies in the construction industry, with the aim of promoting sustainable construction project delivery. The study was conducted using a questionnaire sent to experts in the construction industry. The data collected were analyzed using exploratory factor analysis (EFA) and categorized into operational, management, and demographic variables. Partial Least Square Structural Equation Modeling (PLS-SEM) was used for model development using the four groups of data. In this way, variables that were not significant to the model were identified. Judging from the analysis, there is a need for proper user training in engineering tools in the construction industry. This is one of the drivers of the adoption of 4IR in the construction industry. In addition, the professionals, contractors, authorities, and other stakeholders responsible for managing projects in the architecture, engineering, construction, and operations (AECO) industry should ensure effective coordination and collaboration between participants in the construction industry.

Sustainable building approaches should be included at every level of the development process for maximum benefit without jeopardising the structure’s intended usage. However, researchers have paid less attention to how they may be applied to developing nations. This study aims to investigate the numerous determinants of sustainable delivery in the construction industries of developing nations. For this to happen, existing literature was used to inform the development of a closed-ended questionnaire. Consequently, 95 structured questionnaires by building professionals investigated the importance of these factors. As a result, the factor’s structure was determined and confirmed using the study’s partial least square structural equation modelling (PLS-SEM) approach, which was utilised to investigate the connections between these factors. According to the PLS-SEM analysis, the factors most strongly influencing sustainable delivery are those associated with the preparation, followed by evaluation and use factors, respectively. As a result of this research, authorities in Egypt’s building sector will have a road map for implementing sustainability principles to reduce building costs, boost the local ecosystem, and strengthen social cohesion.

We sought to identify and examine the critical success factors (CSFs) necessary for incorporating cyber technology into residential building projects to augment operational performance and sustainability. An iterative two-stage approach was adopted to explore the phenomena under investigation. General CSFs for cyber technology were first identified from the extant literature, and subsequently explored using primary questionnaire survey data accrued from professionals within the Nigerian building industry. The survey results illustrated that the availability of sensors, good communication networks, mobile devices, and device layers and the creation of workable virtual modes are the main critical success factors for adopting cyber technology. Moreover, Gini’s mean difference measure of dispersion showed that the success factor in stationary cyber technology adoption is government support. The study’s findings guide building industry stakeholders to embrace cyber technology to improve cost and sustainability performance in the Nigerian building industry. Due to the originality of the findings of this study, a strong basis is provided for critically evaluating and analyzing the many vital aspects of cyber technology success.

One of the main components of smart and sustainable urban management is well-performed sewer networks. Therefore, maintaining and enhancing the functionality of sewer projects at an affordable cost are major challenges for decision-makers. However, the embracement of the Value Engineering (VE) concept to assess new sewer designs has not yet been fully embraced especially in developing countries. Thus, this study introduces a systematic VE approach for major sewer projects. A computer model based on six phases of VE methodology was developed, and named “Value Engineering Model” (VEM). To show its efficacy, it was applied to a real-life case study, leading to the following major contributions to the body of relevant knowledge: (1) unraveling the logical relations between the project functions, (2) a detailed life cycle cost analysis (LCCA), (3) a weighted evaluation matrix towards facilitating the decision-making procedure and (4) achieving an approximate 36% reduction in the sewer's project cost as compared to the common VE analysis technique. The developed model serves as a guide for design engineers and decision-makers in sewer projects. It will enable achieving the embracement of smart and sustainable drainage systems within cities at a greater pace. The results of this study will be a guide for decision-makers to reduce costs and improve sustainability by introducing VEs in the Egyptian sewer industry. Refereed/Peer-reviewed

This study aims to model the performance of sewage networks under diverse blockage situations in terms of overflow occurrence using internet-of-things-based technologies in Hong Kong. To this end, a multi-stage methodological approach is employed, starting from collecting required data using smart sensors, utilizing novel data mining techniques, and using a case study simulation. From the results obtained, the following conclusions are drawn: (1) several sites under investigation are imbued with partial blockages, (2) the overall performance of the sewer network has a nonlinear relationship with the blockages in terms of the remaining time to overflow, (3) in cases of complete blockages, the sewer only takes few minutes to reach the manhole cover level that causes the system to experience overflow, and (4) cleaning work significantly improve the performance of the sewage network by 86%. The outcomes of this study provide a solid foundation for the concerned environmental engineers and decision-makers towards reducing the magnitude of sewer overflow and improving different aspects of our environment.

Cloud Computing has become a valuable platform for sustainability in many countries. This study evaluates the cloud computing implementation and its Critical Success Factors (CSFs) towards ensuring sustainable construction projects in Nigeria. Data were collected from previous literature, supplemented by a quantitative approach via a questionnaire survey. Data were collected from 104 construction professionals while cloud computing CSFs were examined using Relative Importance Ranking (RII) and Exploratory Factor Analysis (EFA). The results show that cloud computing’s awareness level is 96.2%, which means that the respondents are aware of cloud computing concept. Furthermore, the result shows that most of the respondents are adopting the concept. The analysis of the CSFs indicated that reliable data storage, performance as well as cost of accessibility and availability were the four most significant CSFs to cloud computing applications. Analysis of the CSFs through EFA generated four main components which include human satisfaction, organization, client’s acceptance, and industry-based. Consequently, this study contributed to existing body of knowledge by highlighting the cloud computing CSFs for achieving sustainable construction project. As such, the results could be a game-changer in the construction industry—not only in Nigeria but also in developing nations where construction projects are implemented through similar style and procedure. This study would be a benchmark for supporting decision-makers to improve data fragmentation, in which the use of data is paramount to the execution of construction works. Finally, the results of this study would be useful for enhancing sustainability and general management of construction projects through cloud computing implementation.

Sustainability principles should be implemented during all the phases of the decision-making process of constructing residential buildings to achieve maximum gains without compromising the function of such projects. This study identified and examined the critical success factors (CSFs) required for implementing value management (VM) in residential building projects. With a view to the sustainability of such the projects. The CSFs for VM were identified from previous studies, which were then contextually adjusted using both semi-structured interviews and a pilot study via the Exploratory Factor Analysis (EFA) technique. The EFA results showed that the VM CSFs could be categorized into four constructs: stakeholders and knowledge, culture and environment, workshop dynamics, and standardization. Questionnaires were then administered to 214 building stakeholders within the Egyptian building industry. Partial least square structural equation modelling (PLS-SEM) was used to develop the CSFs model. Despite that Egyptian professionals with limited practice experiences were quite knowledgeable about VM, results showed that stakeholders and knowledge were crucial CSFs for implementing VM. The results of this study will be a guide for decision-makers to reduce costs and improve sustainability by introducing VMs in the Egyptian construction industry. Refereed/Peer-reviewed

In the last two decades, value management (VM) has become an established construction practice based on fundamental approaches. Implementation of VM activities can contribute to enhancement of the initial objectives in terms of cost, quality, and time. However, the VM activities adopt informal approaches in the Egyptian construction industry. This study aims to develop a VM implementation model by investigating the relationship between VM implementation and the overall project success (OPS) in Egyptian building projects. Fifteen experts were interviewed to assess the VM activities obtained from previous studies. Exploratory factor analysis (EFA) was used to validate the results from the interviews. Structured questionnaires completed by building professionals were further employed to investigate the importance of these VM activities. Partial least squared structural equation modeling (PLS-SEM) was used to determine and confirm the factors structure and examine the relationships between the VM implementation and OPS. The results showed a moderate association, with the implementation of the VM contributing 55.5% to the success of the project. The findings can be used as a benchmark for decision-makers to minimize costs and boost efficiency by implementing VM in the Egyptian construction industry. This study advances the current construction engineering management by improving the understanding of VM methods and activities. Refereed/Peer-reviewed

Value management (VM) is one of the principles adopted by stakeholders to manage issues in the building industry. This paper aims to examine VM diffusion between residential building entities in the Egyptian residential building industry. This research was confined to the Cairo and Giza regions, with enough residential building experience from clients, consultants, and contractors. A quantitative questionnaire survey was generated to find answers from those active in the residential building industry. The results show that although VM’s most widely practiced activities in the Egyptian construction industry are only information phase activities, professionals in Egyptian building projects agreed that all VM activities are important. The results also demonstrated that there is a significant positive correlation among VM phases. The results constitute activities for the adoption of VMs in Egypt. Its guidelines will dramatically enhance the implementation of VMs both in Egypt and in other developing countries where similar projects are conducted. Finally, this research strengthens the residential building industry’s present management by enhancing VM tools and elements to generate value for money. Refereed/Peer-reviewed

The concept of a successful building project should be implemented across the project's lifecycle phases to obtain maximum profits without compromising the standard. Although BIM implementation in developing countries is limited, much research has focused on BIM drivers. However, there is less evidence to thoroughly investigate the influence of BIM barriers and awareness on the project lifecycle. This study addresses barriers to BIM implementation in building projects in developing countries. It investigates the influence of BIM barriers on awareness of BIM during the project lifecycle. Thus, a comprehensive literature review is required to build a conceptual model. Subsequently, the Partial Least Square Structural Equation Modelling (PLS-SEM) was developed using a questionnaire survey tool. Data were collected from 90 building experts in Nigeria. The model's outputs highlighted that cost and standards, process and economic, technology and business, and training and people are the most critical barriers to BIM implementation that should be avoided. Furthermore, the model prediction revealed that eliminating BIM barriers has a minor impact on sufficient knowledge throughout the building project lifecycle. The findings provide the basis for policy making in developing countries concerning the successful completion of projects by avoiding BIM barriers; it will likewise enhance the success of building projects through BIM.
