Abstract Construction workers are often plagued with health and safety challenges on the job site especially in developing countries, largely owing to several factors that encourage poor safety practices on site. This study appraised workers’ perception of management engagement as a critical success factor (CSF) for the improvement of Nigerian construction employee’s safety attitude, using Nordic Occupational Safety Climate Questionnaire (NOSACQ-50). Findings from the study reveal that small scale and medium scale organizations dominate the industry in Nigeria, and a sizable number (20.4%) of the study participants are between 18 and 27 years of age with majority (74.7%) having work experience of 1–10 years. Management safety priority, commitment and competence and management safety empowerment were found to have strong positive correlation. In addition, the study revealed the existence of safety commitment disparity between clients of publicly and privately owned construction projects across the industry. To advance positive safety attitude across the construction industry in Nigeria, management commitment should be prioritised, while further study on workplace safety measures and workers’ safety engagement should be considered.
摘要 建筑工人在工作现场经常受到健康和安全挑战的困扰,尤其是在发展中国家,这主要是由于鼓励现场不良安全做法的若干因素造成的。本研究采用北欧职业安全氛围问卷(NOSACQ-50),评估了工人对管理层参与的看法,将其作为改善尼日利亚建筑员工安全态度的关键成功因素(CSF)。研究结果表明,尼日利亚的中小型组织在该行业中占主导地位,相当多(20.4%)的研究参与者年龄在 18 至 27 岁之间,大多数(74.7%)拥有 1 至 10 年的工作经验。研究发现,管理安全优先权、承诺和能力与管理安全授权具有很强的正相关性。此外,研究还发现,在整个行业中,公有和私有建筑项目的客户在安全承诺方面存在差异。为了在尼日利亚整个建筑行业推广积极的安全态度,应优先考虑管理层的承诺,同时应考虑进一步研究工作场所的安全措施和工人的安全参与度。

AbstractThe modular sector needs a precise guide to determine the most efficient risk management approaches. The main research objective of this study is to develop a multi-criteria decision-making model to find the most efficient risk management approach according to the relevant risk criteria. The risk criteria and risk management approaches for modular construction projects were also identified and classified within this scope. A systematic literature review, semi-structured interviews, and open-ended questionnaires were performed for identification and classification purposes. For ranking and quantifying the identified risks and risk approaches, as well as developing the decision-making model, the Delphi method and the Analytical Hierarchy Process (AHP) were conducted. A two-round Delphi method, with eleven experts, was conducted to achieve efficient performance scores of the identified risk management approaches. The percentage standard deviation decreased, Relative Importance Index (RII), Cronbach’s alpha, and Kendall’s coefficient of concordance (Kendall’s W) were calculated to ensure the outputs’ reliability, validity, and agreement level. The AHP method opted to quantify the Delphi method outputs, solve the multi-criteria decision-making process, and develop the multi-criteria decision-making model for risk management of modular construction projects. Triangulation results show that the critical risk categories are supply chain, health and safety, stakeholders, and governmental support. Lean principles such as the Last Planner System, Value Stream Mapping, Just in Time, and Kaizen are top-rated risk management approaches. This research’s novelty is identifying and analyzing crucial risk categories, providing the relevant risk management approaches ranked according to efficiency performance, and presenting a decision-making model as a guideline for risk management of modular construction projects.Keywords: Modular constructionrisk managementmulti-criteria decision-makingoff-site constructiondelphi methodconstruction management; analytic hierarchy process Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data used in this study with unique DOIs for the qualitative and quantitative analysis spreadsheets are available from the corresponding authors upon reasonable request.
摘要模块化领域需要一个精确的指南来确定最有效的风险管理方法。本研究的主要研究目标是建立一个多准则决策模型,根据相关的风险准则寻找最有效的风险管理方法。在此范围内,对模块化建设项目的风险标准和风险管理方法进行了识别和分类。系统的文献回顾,半结构化访谈和开放式问卷调查进行了识别和分类的目的。采用德尔菲法和层次分析法(AHP)对已识别的风险和风险途径进行排序和量化,并建立决策模型。采用由11位专家组成的两轮德尔菲法,对确定的风险管理方法进行了有效的绩效评分。降低百分比标准差,计算相对重要指数(RII)、Cronbach’s alpha和Kendall’s consistency coefficient (Kendall’s W),以保证输出的信度、效度和一致性水平。层次分析法选择对德尔菲法的结果进行量化,解决多准则决策过程,建立模块化建设项目风险管理的多准则决策模型。三角测量结果显示,关键风险类别为供应链、健康与安全、利益相关者和政府支持。精益原则,如最后的计划系统,价值流映射,及时,和改善是最高评级的风险管理方法。本研究的新颖之处在于识别和分析关键风险类别,根据效率绩效提供相应的风险管理方法,并提出决策模型作为模块化建设项目风险管理的指导。关键词:模块化施工;风险管理;多准则决策;披露声明作者未报告潜在的利益冲突。数据可用性声明本研究中使用的数据具有独特的DOIs用于定性和定量分析电子表格,应合理要求从相应作者处获取。

AbstractMany industry disputes originate during the pre-contract stage, emphasizing the importance of preventing these issues early on rather than relying on post-facto resolutions. Therefore, professionals need to act proactively to avoid lapses in the pre-contract stage from the initial stage of the construction project. However, the current literature lacks an investigation of dispute avoidance by identifying professionals involved in the pre-contract phase of construction projects. This research, thus, aims to investigate the strategies to avoid disputes in construction projects in the pre-contract stage from the perspective of responsible professionals. The study adopted a qualitative approach by conducting semi-structured interviews among 15 industry practitioners involved in dispute management practices, selected through purposive sampling. The data collected was analyzed using the N-Vivo12. The findings revealed 48 lapses in the pre-contract stage and 104 strategies to avoid disputes. The findings further revealed that most of the lapses occurred during the technical stage. In contrast, the architects are responsible for design errors, and quantity surveyors contribute to documentation issues. The research offers a comprehensive framework for professionals and regulatory authorities to encourage dispute mitigation efforts, thereby contributing to the body of knowledge.Keywords: Dispute avoidancelapsespre-contractprofessionalsRIBA 2020strategies Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe data that support the findings of this study are available from the corresponding author, [Liynawatta T.N.], upon reasonable request.
摘要许多行业纠纷发生在合同前阶段,强调了早期预防这些问题的重要性,而不是依赖于事后解决。因此,专业人员需要从建设项目的初始阶段就主动采取行动,避免在合同前阶段出现失误。然而,目前的文献缺乏通过确定参与建设项目合同前阶段的专业人员来避免纠纷的调查。因此,本研究旨在从责任专业人员的角度,探讨在合同前阶段避免建筑项目纠纷的策略。本研究采用定性方法,通过有目的的抽样选择,对参与争议管理实践的15名行业从业者进行了半结构化访谈。使用N-Vivo12对收集的数据进行分析。调查结果揭示了合同前阶段的48个失误和104个避免纠纷的策略。调查结果进一步表明,大多数故障发生在技术阶段。相比之下,建筑师要对设计错误负责,而工料测量师要对文件问题负责。这项研究为专业人员和管理当局提供了一个全面的框架,以鼓励缓解争端的努力,从而促进知识体系。关键词:争议规避、合同前专业人员、riba 2020策略披露声明作者未报告潜在的利益冲突。数据可用性声明支持本研究结果的数据可根据合理要求从通讯作者[Liynawatta T.N.]处获得。

AbstractResource availability is the crucial factor of construction project scheduling decision, as it impacts the time and cost of the project. However, traditional researches assume that resource availability is fixed, which does not reflect the actual situation. This article proposes a model for addressing the multimode variable resource-constrained time/cost trade-off problem (Mvrc-DTCTP) in repetitive projects. To better capture the characteristics of repetitive projects, an adjustment strategy is designed to mitigate the impact of work continuity interruptions on idle time. Through simulation analysis, it was found that increasing resource supply can reduce project duration, but it is not directly proportional to cost. This phenomenon further increases the uncertainty in the relationship between duration and cost, inevitably affecting managers’ ability to develop effective scheduling plans. By employing the Mvrc-DTCTP model, project managers can obtain more and better solutions than traditional methods, with shorter duration, and lower total cost. The proposed adjustment strategy results in a 54% reduction in idle time, a $4000 cost reduction and more feasible solutions. Based on calculations for 30 randomly generated cases, the adjustment strategy achieves optimization rates ranging from 24.43% to 84.24%. The adjustment strategy demonstrates the best optimization effect when the resource supply level is moderate.Keywords: Variable resource supplywork continuitydiscrete time/cost trade-offrepetitive projectmultimode resource-constrained Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementData available within the article or its supplementary materials.
摘要资源可获得性是建设项目进度决策的关键因素,它影响着项目的时间和成本。然而,传统研究假设资源可用性是固定的,这与实际情况不符。本文提出了一个解决重复项目中多模式可变资源约束时间/成本权衡问题(Mvrc-DTCTP)的模型。为了更好地捕捉重复性项目的特征,设计了一种调整策略,以减轻工作连续性中断对空闲时间的影响。通过仿真分析发现,增加资源供给可以缩短项目工期,但与成本不成正比。这种现象进一步增加了工期与成本关系的不确定性,不可避免地影响管理者制定有效调度计划的能力。采用Mvrc-DTCTP模型,项目经理可以获得比传统方法更多更好的解决方案,工期更短,总成本更低。提出的调整策略使闲置时间减少了54%,成本降低了4000美元,并提供了更可行的解决方案。通过对30个随机生成案例的计算,调整策略的优化率在24.43% ~ 84.24%之间。当资源供给水平适中时,调整策略的优化效果最佳。关键词:可变资源供给工作连续性离散时间/成本权衡重复项目多模式资源约束披露声明作者未报告潜在的利益冲突。数据可用性声明文章或其补充材料中可用的数据。

AbstractCertainty, commitment, and communication are essential requirements which seem to be eluding the existing contracting process giving rise to claims and disputes. Contract management practices continue to be manual and traditional despite the digital and technological developments in construction sector. Blockchain technology is increasingly used in different aspects of the business world with its intrinsic qualities of transparency and security. This research conducts systematic literature reviews in three areas aiming to: analyse the chronic problem of construction disputes, investigate recent methods and tools of contractual dispute avoidance, and provide a compelling rationale for the integration of blockchain technology into the contracting process. While the ‘contract-related’ issues were found to be the leading cause of disputes, a ‘centralized’ hierarchy-based environment was established as one of the key challenges to dispute avoidance mechanisms. Discussion followed by feedback survey from industry experts further validated the literature review results. Based on the findings, an integrated blockchain-based conceptual framework is proposed illustrating a contracting process that is: (1) efficient and transparent; (2) digitally integrated; and (3) trustworthy and secure in execution. The study reviews the existing practices and challenges in contract management and offers an interdisciplinary and novel approach for future research in this domain.Keywords: Automationblockchaincollaborationcontract managementdispute causedispute avoidancesmart contract Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementSome or all data that support the findings of this study are available from the corresponding author upon reasonable request.
摘要确定性、承诺和沟通是现有合同过程中不可缺少的基本要求,这些要求往往会引起索赔和纠纷。尽管建筑行业的数字和技术不断发展,合同管理实践仍然是手工和传统的。区块链技术以其固有的透明性和安全性越来越多地应用于商业世界的各个方面。本研究在三个领域进行了系统的文献综述,旨在:分析建筑纠纷的长期问题,调查合同纠纷避免的最新方法和工具,并为将区块链技术整合到合同过程中提供令人信服的理由。虽然“合同相关”问题被认为是争议的主要原因,但建立一个“集中的”基于等级的环境是争议避免机制的主要挑战之一。随后的讨论和行业专家的反馈调查进一步验证了文献综述的结果。根据研究结果,提出了一个基于区块链的集成概念框架,说明了一个合同流程:(1)高效透明;(2)数字集成;(三)执行可靠、安全。该研究回顾了合同管理的现有实践和挑战,并为该领域的未来研究提供了跨学科和新颖的方法。关键词:自动化、区块链协作、合同管理、争议原因、争议规避、智能合同披露声明、作者未报告潜在利益冲突。数据可用性声明支持本研究结果的部分或全部数据可根据通讯作者的合理要求获得。

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.
摘要尽管绿色城市的重要性和文献中的贡献越来越大,但城市仍然面临着规划不善、洪水和贫民窟等挑战,尤其是在包括加纳在内的非洲。然而,没有任何研究调查加纳发展绿色城市所需的可持续性内容。有鉴于此,本研究的主要目的是探索支撑加纳绿色城市发展的关键可持续性内容。在使用定量设计时,从综合文献综述中确定了20个变量,并对154名具有绿色城市发展经验的专业人员进行了定量调查。基于描述性统计和探索性因素分析,提出了四大类,即可持续城市规划、可持续城市管理、综合可持续城市设计、可持续城市和遗产保护。这项研究为绿色城市发展的关键绿色内容提供了见解,这将对学术界、行业从业者和政策制定者有用。尽管这项研究的地理范围仅限于加纳,但研究结果可能适用于与加纳城市具有相似特征的发展中国家其他城市。

AbstractA sudden COVID-19 outbreak has significantly impacted construction site health and safety (H&S). Against this backdrop, this paper aimed to explore the major challenges for pandemic management in implementing COVID-19 H&S measures on construction sites, particularly in developing countries. Following a comprehensive literature review, a total of 20 relevant challenges were identified. A self-completion questionnaire survey involving Malaysian construction practitioners was further employed to prioritize these challenges using descriptive statistics. Finally, a factor analysis unfolded five major underlying dimensions of these challenges, relating to lack of resources and inherent nature of construction, negligence and ignorance, low-wage blue-collar workforce, ineffective H&S management and poor sanitizing and disinfecting strategies. This work is a valuable reference in assisting industry practitioners to further enhance H&S performance during a communicable disease outbreak such as the COVID-19 pandemic. In particular, the findings highlighted the current deficiencies of the H&S system in the context of a developing country and the necessity to devise responsive strategies in curbing the transmission of future diseases.Keywords: Challengesconstruction industryCOVID-19 pandemicdeveloping countrieshealth and safety measuressafety management AcknowledgementsThe authors express their sincere thanks to all the industry practitioners who have participated in the data collection process.Disclosure statementNo potential conflict of interest was reported by the authors.Data availability statementAll data, models and code generated or used during the study appear in the submitted article.Additional informationFundingThe authors would like to acknowledge the Ministry of Education Higher Malaysia (MOHE) for financial support under Fundamental Research Grant Scheme (FRGS) Project Number: FRGS/1/2022/SS02/UTAR/02/1 for the project entitled ‘Technology Readiness Index (TRI) for the adoption of innovative technologies in construction safety science and management in Malaysia’ and UTAR Research Fund (UTARRF) Project Number: IPSR/RMC/UTARRF/2021-C1/J01.
摘要新型冠状病毒肺炎(COVID-19)突发性疫情对建筑工地健康安全造成重大影响。在此背景下,本文旨在探讨在建筑工地实施COVID-19卫生与安全措施时,特别是在发展中国家,大流行管理面临的主要挑战。在全面的文献综述之后,共确定了20个相关挑战。一项涉及马来西亚建筑从业人员的自我完成问卷调查进一步采用描述性统计来优先考虑这些挑战。最后,因子分析揭示了这些挑战的五个主要潜在维度,包括缺乏资源和建筑的固有性质、疏忽和无知、低工资蓝领劳动力、无效的卫生与安全管理以及糟糕的消毒和消毒策略。这项工作对协助行业从业者在COVID-19大流行等传染病暴发期间进一步提高卫生与安全绩效具有重要参考价值。特别是,调查结果突出了卫生与健康系统在发展中国家背景下目前的缺陷,以及为遏制未来疾病的传播制定响应性战略的必要性。关键词:挑战建筑行业covid -19大流行发展中国家健康与安全措施安全管理致谢作者对所有参与数据收集过程的行业从业者表示衷心的感谢。披露声明作者未报告潜在的利益冲突。数据可用性声明在研究过程中生成或使用的所有数据、模型和代码都出现在提交的文章中。作者要感谢马来西亚高等教育部(MOHE)在基础研究资助计划(FRGS)项目编号:FRGS/1/2022/SS02/UTAR/02/1下为题为“在马来西亚建筑安全科学和管理中采用创新技术的技术准备指数(TRI)”和UTAR研究基金(UTARRF)项目编号:IPSR/RMC/UTARRF/2021-C1/J01”的项目提供财政支持。
