Abstract Despite the growing importance of green cities and the contributions in literature, cities still face challenges such as poor planning, flooding, and slums especially in Africa including Ghana. Yet, no study has investigated the sustainability content required to develop green cities in Ghana. In view of this, the primary aim of this study is to explore the key sustainability content underpinning green cities development in Ghana. In using the quantitative design, 20 variables were identified from a comprehensive literature review, and a quantitative survey was performed with 154 professionals with green cities development experience. Based on descriptive statistics and exploratory factor analysis, four major categories were developed namely, sustainable city planning, sustainable city management, integrative sustainable city design, and sustainable city and heritage preservation. This study provides insights into key green content for green cities development which will be useful to academia, industry practitioners, and policymakers. Although this study was limited in geographical scope to Ghana, the findings may apply to other cities in developing countries that share similar characteristics with Ghanaian cities.

AbstractWind flow pattern and generation of strong and large eddies is mainly responsible to the wind pressure and suction intensity in and around the tall building. If the shape of the structure is not vary common then the wind generated effects need to evaluate for the high rise structure this is because of the reason that the data for the regular plan cross sectional shape is available in the various international standards. This study investigating the wind effects on irregular cross sectional shape tall building using CFD tool ANSYS CFX. The current study evaluates the wind impacts for a boundary layer atmospheric wind flow from 0° to 180° at a 15° interval. The power law described in IS: 875 (Part 3): 2015 for terrain category II follows the wind profile. For a rectangular model, the values of the pressure coefficients are compared using the numerical simulation and the information supplied in IS 875. Results are given at numerous locations, including pressure coefficients around the building model’s periphery and force and moment coefficients for wind incidence angles ranging from 0° to 180° at 15° intervals.Keywords: Irregular modelC shape modeltall buildingCFDpressure around the buildingforce and moment coefficients Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was funded by Delhi Technological University.

AbstractThe purpose of this study is to develop a comprehensive fuzzy-based multi-criteria decision-making (MCDM) methodology to generate ranking of risk factors on Indian tunnel projects. The complexities and high costs involved in tunnelling projects create a strong necessity to look into quantitative risk assessment so as to prevent project underperformance. The analysis of large number of risk factors makes the task difficult. Thus, the present study attempts to address this challenge by developing a comprehensive framework for risk prioritization. In the previous work, critical risk factors (CRFs) were identified using Relative importance Index from the factor pool. The present study utilizes the Analytic Hierarchy Process approach for the identification of CRFs. The list of 25 critical factors, obtained by integrating both RII and AHP results, is further analyzed using the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (Fuzzy TOPSIS), based on three criteria, probability of occurrence, impact and cost. The methodology developed in this work will help in selecting the most significant risk factors, thus substantially improving the risk analysis process on Indian tunnel projects. This study contributes towards the development of framework for risk prioritization which will be useful for researchers and practitioners.Keywords: Multi-criteria-decision-making (MCDM)risk prioritizationtunnel projectsfuzzy TOPSISAHPIndian tunnel projects AcknowledgementThe authors thank the anonymous reviewers who carefully reviewed the paper and whose suggestions were useful in improving the manuscript to a great extent.Competing interestsThe authors have no relevant financial or non-financial interests to disclose.Author contributionsNivedita Gogate and Abhaysinha Shelake contributed to the study conception and design.

AbstractThe Oil and Gas (O&G) industry is complex and hazardous. Its development relies on projects, where project management is a human-centred profession. Therefore, competent project managers (PMs) play a crucial role in this dynamic industry. Existing literature has primarily focused on the quantitative impact of project managers’ competencies (PMCs) on project success (PS). However, there has been little attention given to understanding the ‘how’ behind the contributions of PMCs, specifically behavioural competencies (BCs), to PS. As a result, this research aims to explore the perspectives of PMs regarding the contributions of BCs to the success of projects in the O&G industry. This paper takes an interpretive stance. Data was gathered through twenty semi-structured interviews with PMs from a refinery in the Kingdom of Bahrain and analysed using thematic analysis with the aid of NVIVO 12. The study revealed the ways in which BCs contribute to project success in the O&G industry. Five distinct mechanisms were identified for BCs’ contributions to PS: fostering team cohesiveness, enhancing work clarity, controlling project activities, conveying technical competencies, and advancing PMs’ careers. This study was conducted in an under-researched industry within a developing country and has provided a deeper understanding of the means by which BCs contribute to PS, rather than merely presenting them as an extensive ‘shopping list’.Keywords: Behavioural competenciesproject successoil and gas Disclosure statementNo potential conflict of interest was reported by the authors.

AbstractOver the past 20 years, value management (VM) has become a well-established technique, while in underdeveloped countries; informal methods are used for VM-related activities. This study aims to examine the barriers to VM deployment. These barriers are categorized into environment and culture, workshop dynamics, knowledge and stakeholders and standardization. A review of prior research is conducted to identify these barriers, which are further categorized through a semi-structured interview. The significance of these barriers is determined through 335 structured surveys with building specialists. The four categories of barriers are then assessed using fuzzy synthetic evaluation and weighted aggregated sum product assessment—technique for order of preference by similarity to ideal solution methods. In addition, a stationary method is used to evaluate the incorporation of VM barriers into residential projects. According to the findings, the most significant category of barriers that hinder the widespread use of VM is knowledge and stakeholders. Among these categories, the most influential barriers that constrain the VM implementation are workshop decision-maker participation issues. This research provides a roadmap for effective VM adoption in developing countries by helping stakeholders in the residential building industry understand VM barriers and leverage them to enhance the value of their projects.Keywords: Value managementimplementation barriersresidential building projectsMulti-Criteria evaluationstationary analysis Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data will be available upon request.Additional informationFundingThis study was supported via funding from Prince Sattam bin Abdulaziz University project number (PSAU/2023/R/1445).

Purchasing is a fundamental step of materials procurement in the construction sector, and since materials can represent up to 70% of the project’s construction costs, reducing wastage and improving productivity can have big benefits, both for the environment and the economy, especially for Micro, Small and Medium-sized Enterprises (MSMEs). This manuscript will focus on the process of purchasing materials from these companies’ perspective, seeking to investigate the impact of effective materials management on site. In light of the acknowledged absence of system thinking for MSMEs, this research aims to build a new conceptual framework that illustrates the complexity of the materials purchasing process in construction and embodies the risks linked to materials, relationships, information and cash flows. The conceptual framework aims to influence supply management in construction and is based on the recognition of five main levels, going from the specification of materials to data management and feedback. It is designed to illustrate the sequence, logical structure and complexities of the purchasing process. Data from the literature, followed by on-site observations, feeds into the framework.

Project managers often find it a challenge to successfully manage construction projects. As a result, understanding, evaluating, and achieving project success are critical for sponsors to control projects. In practice, determining key success factors and criteria to assess the performance of construction projects and forecast the success of new projects is difficult. To address these concerns, our objective is to go beyond the efficiency-oriented project success criteria by considering both efficiency- and effectiveness-oriented measures to evaluate project success. This paper contributes to existing knowledge by identifying a holistic and multidimensional set of project success factors and criteria using a two-round Delphi technique. We developed a decision support system using the Adaptive Neuro-Fuzzy Inference System (ANFIS) to forecast the success of mid- and large-sized construction projects. We gathered data from 142 project managers in Australia and New Zealand to implement the developed ANFIS. We then validated the constructed ANFIS using the K-fold cross-validation procedure and a real case study of a large construction project in Western Australia. The forecasting accuracy measures R2=0.97461, MAPE = 2.57912%, MAE = 1.88425, RMSE = 2.3610, RRMSE = 0.03149, and PI = 0.01589 suggest that the developed ANFIS is a very good predictor of project success.
项目经理经常发现成功管理建设项目是一项挑战。因此,理解、评估和实现项目成功对于发起人控制项目是至关重要的。在实践中,确定关键的成功因素和标准来评估建设项目的绩效和预测新项目的成功是困难的。为了解决这些问题,我们的目标是通过考虑以效率和有效性为导向的方法来评估项目成功,从而超越以效率为导向的项目成功标准。本文通过使用两轮德尔菲技术确定项目成功因素和标准的整体和多维集,为现有知识做出贡献。我们开发了一个决策支持系统,利用自适应神经模糊推理系统(ANFIS)来预测中大型建设项目的成功。我们从澳大利亚和新西兰的142个项目经理那里收集了数据,以实施开发的ANFIS。然后,我们使用K-fold交叉验证程序和西澳大利亚州一个大型建筑项目的真实案例研究验证了构建的ANFIS。预测精度指标R2=0.97461, MAPE = 2.57912%, MAE = 1.88425, RMSE = 2.3610, RRMSE = 0.03149, PI = 0.01589表明开发的ANFIS可以很好地预测项目成功。

AbstractEnvironmental degradation is an alarming threat to human security and green procurement has been regarded as one of the remedial measures to alleviate the environmental issues. Considering that the green procurement is a relatively new concept in the Malaysian construction industry, this study investigated the green procurement in construction projects by exploring its benefits towards the environment, economic and social aspects. Drawing on an empirical survey in Malaysia, the significant benefits of green procurement applications are prioritised. A total of 150 surveys were collected among developers, consultants, contractors and suppliers and analysed using SPSS version 23.0 statistical software. The findings suggested that the primary benefits of adopting green procurement practices are reduce pollution levels, improve community health and quality of life, conserve natural resources, reduce greenhouse gases and provide healthier working environment. This paper provides the basis for construction procurement delivery to be on a sustainable path.Keywords: Green procurementconstructionbenefitssustainabilityquestionnaire Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingWe want to thank UTAR Research Fund (UTARRF) (IPSR/RMC/UTARRF/2022-C1/L07) and Institut Pengurusan dan Pemantauan Penyelidikan, Universiti Malaya, IIRG fund (IIRG004C(D)-2021IISS) for supporting this research.

AbstractMechatronics has emerged as a transformative approach in the architecture, engineering, construction and operation (AECO) industry, revolutionizing project design, execution and management. By integrating cutting-edge technologies, mechatronics brings numerous benefits, including improved efficiency through task automation, reduced errors and increased productivity. However, despite its potential, implementing mechatronics in AECO projects presents significant challenges. Therefore, the objective of this study is to identify and evaluate strategies that promote the understanding and utilization of mechatronics in AECO projects, focusing on the Nigerian context. To achieve this objective, a comprehensive literature review was conducted, resulting in the identification of 18 strategies. These strategies formed the basis for a questionnaire survey, which examined their criticality and relevance. The findings highlighted the top five critical strategies: developing specialized training programs for mechatronics implementation, endorsing and promoting through government channels, collaborating with industry influencers and professional associations, attracting investment for mechatronics and promoting industry-recognized certifications. Additionally, a principal component analysis revealed four latent factors that encompassed the identified strategies: training and talent-building, awareness and amplification, investment and incentives, and policy and progression. To validate and enhance the findings, a comparative analysis was conducted, comparing the results from this study with similar cases in China, South Africa and the United States. The implications of this study extend to industry practitioners, policymakers, educators and researchers, providing valuable insights and recommendations for promoting mechatronics in the AECO industry. By embracing these implications, stakeholders can contribute to the industry’s transformation, enhancing efficiency, productivity and overall project outcomes.Keywords: Automationconstruction efficiencyconstruction projectselectronic systemsmechanical engineeringmechatronic technologiesrobotics Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementAll data or codes generated or used during the study are available from the corresponding author by request.Additional informationFundingThe authors have no relevant financial or non-financial interests to disclose.
