Strategic planning of BIM adoption has become increasingly important, owing to the need to minimise BIM adoption risks, maximise BIM benefits, and ensure successful BIM adoption. Our understanding of strategic planning of BIM adoption in a developing country is limited. Therefore, this study develops a framework for strategic BIM adoption on construction projects. The applicability of the framework was tested by using it to analyse the pattern of BIM adoption on construction projects in South Africa. Findings of the study demonstrate interrelationships between project milestones and deadlines, the extent of use of BIM software platforms used for the BIM-based construction projects (BBCPs), and the extent of collaboration on the BBCPs. The findings also confirm interrelationships between the regulatory system, the extent of use of BIM software platforms, the extent of collaboration, and the extent of integration on the BBCPs. This research has shown that the strategic planning of BIM adoption enables the proper management of BIM tools and processes. The research has also provided practical guidelines for strategic planning of BIM adoption in developing countries.
BIM采用的战略规划变得越来越重要,因为需要最小化BIM采用风险,最大化BIM收益,并确保成功采用BIM。我们对发展中国家采用BIM的战略规划理解有限。因此,本研究为BIM在建筑项目中的战略性采用开发了一个框架。通过分析南非建筑项目采用BIM的模式,测试了该框架的适用性。研究结果显示了项目里程碑和截止日期之间的相互关系,基于BIM的建筑项目(bbcp)使用BIM软件平台的程度,以及bbcp上的合作程度。调查结果还证实了监管体系、BIM软件平台的使用程度、协作程度和bbcp集成程度之间的相互关系。这项研究表明,采用BIM的战略规划能够对BIM工具和流程进行适当的管理。该研究还为发展中国家采用BIM的战略规划提供了实用指南。

A hostel facility's effective functioning and performance contribute significantly to advancing knowledge and technologies for a sustainable future. Therefore, post-occupancy evaluation (POE) offers the basis for promoting construction projects' future design and construction quality. The present study thereby examines the maintenance feedback mechanisms and limiting factors of POE to address future occupants' satisfaction in selected hostels in Nigerian universities. A quantitative research design method was adopted where 340 questionnaire instruments were administered to the student's occupants and facilities managers. The data obtained were subjected to descriptive statistics using a mean score, relative importance index, and ranking. The research findings revealed that the maintenance feedback mechanisms utilised both by the student and facilities manager respondents have direct communication channels with the relevant stakeholders. The limiting factors of POE analysed showed that non-availability of information on building facilities, the persistence of maintenance challenges in building, lack of commitment from school management, and insignificant improvement on the maintenance challenges were severe factors to be tackled in the studied hostels. Therefore, it is recommended that Nigerian universities' regulating body conduct a building performance evaluation of existing hostel facilities in Nigerian universities and update the procedures guide and physical development manual for Nigeria's university system.
旅舍设施的有效运作和表现,对推动知识和技术的发展,为可持续发展的未来作出重大贡献。因此,使用后评价(POE)为促进建设项目未来的设计和施工质量提供了依据。因此,本研究考察了POE的维护反馈机制和限制因素,以解决尼日利亚大学选定宿舍未来居住者的满意度问题。采用定量研究设计方法,对学生住户和设施管理人员进行了340份问卷调查。获得的数据使用平均得分、相对重要性指数和排名进行描述性统计。研究结果显示,学生和设施经理受访者使用的维护反馈机制与相关利益相关者有直接的沟通渠道。对POE的限制因素分析表明,建筑物设施信息的不可获得性、建筑物维修挑战的持续性、学校管理层缺乏承诺以及维修挑战的改善效果甚微是所研究的宿舍需要解决的严重因素。因此,建议尼日利亚大学的监管机构对尼日利亚大学现有的宿舍设施进行建筑性能评估,并更新尼日利亚大学系统的程序指南和物理开发手册。

Apprenticeships provide young people with training and improve the supply of workers to the construction sector. In Nigeria, there is a large influx of craftspeople from neighbouring countries. This situation has led to an increase in the rate of youth employment. The current study seeks to address the following questions: (i) what are the factors responsible for the noncompletion of construction crafts apprenticeship? And (ii) what are the determinants of successful completion of construction crafts apprenticeship? Forty-six (46) semi-structured interviews were conducted with relevant stakeholders involved in apprenticeship in Lagos State, Nigeria. The study reveals that "lack of information on the content of training programme," "financial difficulties," "bullying," "lack of interest," and "work-life balance" as factors responsible for non-completion. In contrast, it was found that "personal interest and motivation," "parental and family support," "personality of the trainer," and "potential to earn income" are determinants of successful completion of construction crafts apprenticeship. This finding can be used to develop strategies for improving outcomes of construction craftspeople apprenticeships. The study contributes to the knowledge on apprenticeships in the field of construction and vocational education.
学徒制为年轻人提供了培训,并改善了建筑行业的工人供应。在尼日利亚,有大量来自邻国的手工艺人涌入。这种情况导致了青年就业率的上升。本研究旨在探讨以下问题:(i)造成建筑工艺学徒未完成的因素是什么?以及(ii)成功完成建筑工艺学徒的决定因素是什么?对尼日利亚拉各斯州学徒制的相关利益攸关方进行了46次半结构化访谈。研究表明,“缺乏培训内容的信息”、“经济困难”、“欺凌”、“缺乏兴趣”和“工作与生活的平衡”是导致无法完成培训的因素。相反,“个人兴趣和动机”、“父母和家庭支持”、“培训师的个性”和“赚取收入的潜力”是成功完成建筑工艺学徒的决定因素。这一发现可用于制定策略,以改善建筑工匠学徒的结果。该研究有助于了解建筑和职业教育领域的学徒制。

The COVID-19 pandemic has altered every industry’s operations and safety requirements, including that of the construction industry. Different measures are thus required to mitigate the spread of the disease among construction site workers. This paper explores the basic measures construction organisations have instituted at construction project sites to curb the spread of the virus among construction site workers. A qualitative research method was adopted for the study, while data were collected through open-ended questions. Summative content analysis was employed to analyse the qualitative data and determine the frequency of keywords that were further translated to quantitative measurements. The study determined that construction organisations have largely instituted some basic measures to curb the spread of COVID-19 on sites, whereas most organisations were lacking in the area of social distancing. COVID-19 is still new; therefore, the body of knowledge is still at the infancy stage. To date, there is no evidence of empirical studies that addressed the compliance level of the Nigerian construction organisations with basic measures of curtailing the spread of COVID-19. Policymakers could adopt the interventions arising from this study to mitigate the spread of the virus.
新冠肺炎大流行改变了包括建筑行业在内的每个行业的运营和安全要求。因此,需要采取不同的措施来减轻疾病在建筑工地工人中的传播。本文探讨了建筑施工组织在建筑工地采取的基本措施,以遏制病毒在建筑工地工人中的传播。本研究采用定性研究方法,采用开放式问题收集数据。采用总结性内容分析对定性数据进行分析,确定关键词的出现频率,并进一步转化为定量测量。该研究确定,建筑组织在很大程度上制定了一些基本措施来遏制COVID-19在工地上的传播,而大多数组织在社交距离方面缺乏。COVID-19仍然是新的;因此,知识的主体还处于起步阶段。迄今为止,没有实证研究的证据表明,尼日利亚建筑组织遵守了遏制COVID-19传播的基本措施。决策者可以采用这项研究提出的干预措施来减轻病毒的传播。

This paper assesses the causative characteristics of abandoned completed urban market projects in the Bono Region, Ghana, and its associated effect. The study used the mixed methodology research approach. Eight abandoned completed urban market projects were visited within the region. A total of sixteen consultant and contractor teams were selected using the purposive sampling technique. Thirty-two (32) questionnaires were administered and received from would-be users, consultants, and contractors of the eight selected projects. Bad location, non-provision of auxiliary facilities, high rent charges, long distance from the communities, small size of sheds and stalls and non-user consultation were the highest causative characteristics. The effects of abandon markets were resource wastage, unemployment, and decrease in revenue accruable to the state. Markets are a source of product delivery that promotes sustainable economic development, jobs, communication and enhances the identity of the communities. Wastage of resources occurs if an urban market project is abandoned. Improvement of would-be user’s satisfaction is imperative to reduce non-usage leading to the abandonment of market project. Therefore, auxiliary utilities such as electricity, water, sanitation, and access roads must be included in the project at the planning phases. The paper affirms the relevance of user satisfaction of urban market projects to avoid wastage of public resources.
本文评估了加纳波诺地区废弃的已完工城市市场项目的成因特征及其相关效应。本研究采用混合方法学研究方法。在该区域内访问了八个废弃的已完成的城市市场项目。采用有目的抽样技术共选择了16个顾问和承包商小组。对八个选定项目的潜在用户、顾问和承包商进行了32份问卷调查。位置差、不提供辅助设施、租金高、距离社区远、棚舍和摊位规模小以及未经用户咨询是最主要的原因。放弃市场的影响是资源浪费、失业和国家可获得收入的减少。市场是产品交付的来源,促进可持续经济发展、就业、交流和增强社区的身份。放弃城市市场项目会造成资源浪费。提高潜在用户的满意度是减少因不使用而导致市场项目放弃的必要条件。因此,在规划阶段必须将电、水、卫生、通道等辅助设施纳入项目。本文肯定了城市市场项目用户满意度与避免公共资源浪费的相关性。

Employee turnover costs pose a big challenge for many companies. Studies show that employee turnover can cost about twenty per cent of the salaries in hiring, training, and lost productivity, although estimates give much higher figures. Therefore, company management must have a strategy in terms of retaining employees to avoid the desire of moving (turnover intention) from the company. This study aims to analyze the turnover intention of construction employees by extending the planned behaviour model's theory. The research method used is a survey method with a quantitative descriptive approach. The population in this study are employees who work in construction companies in Indonesia. Sampling method using non-probability sampling technique, namely using a convenience sampling technique is employed in the current study. A questionnaire was used to collect data from 197 respondents. The data were collected and analyzed using Structural Equation Modeling (SEM) techniques, using maximum likelihood estimation with covariance matrix as the input with Amos 24 software. The results indicated that attitude and perceived behavioral control had a positive and significant effect on Turnover Intention. In contrast, subjective norm had a positive but not significant effect on Turnover Intention. Subjective norm indirectly had a significant effect on Turnover Intention through attitude and perceived Behavioral Control.
对许多公司来说,员工流动成本是一个巨大的挑战。研究表明,员工流动在招聘、培训和生产力损失方面的成本约占工资的20%,尽管估计数字要高得多。因此,公司管理层必须有一个留住员工的策略,以避免公司的移动欲望(离职意图)。本研究旨在通过扩展计划行为模型的理论来分析建筑员工的离职倾向。使用的研究方法是定量描述方法的调查方法。本研究的人群是在印度尼西亚建筑公司工作的员工。抽样方法采用非概率抽样技术,即采用方便抽样技术。使用问卷收集197名受访者的数据。数据的收集和分析采用结构方程建模(SEM)技术,使用Amos 24软件以协方差矩阵为输入的最大似然估计。结果表明,态度和知觉行为控制对离职倾向有显著的正向影响。主观规范对离职倾向的影响为正但不显著。主观规范通过态度和知觉行为控制间接影响离职倾向。

Rural development projects are essential as a catalyst for balanced development between urban and rural areas as well as tools for enhancing the living standard of rural poor. This study focuses on the identification of factors that influence the governance practices in a rural road project in Malaysia. A single case study was conducted from the perspective of a stewardship theoretical lens on a rural road project in East Malaysia, and multiple sources of evidence were used for data collection. The study discovered four (4) main factors namely intrinsic motivation, altruistic empathy, effective leadership, and shared vision that influence project governance practices in this project. Thus, this article contributes towards a better understanding of the interplay of these motivating factors, which drives public officials in different project actors for effective delivery in this project context. The findings of the study are limited to the utilization of a single case study related to the rural road project and its contexts.

Variability in labour productivity is a performance inhibitor and a determinant of effective and ineffective projects. It has hampered the intercomparison of construction projects and the accurate forecasting of project duration and cost. This study chose wall plastering activities as a case study. This study aims to quantify the impact of work environment factors on the variability of labour productivity. Data were collected using direct site observations and structured questionnaires. The results revealed that waiting for materials (62.4%), being on the job but not working (52.6%), and work area congestion (52.5%) all had negative effects on labour productivity variance. Other negative factors include rework (51.7%), waiting for tools/equipment (51.1%), waiting for information (47.2%) and weather changes. The overall average daily productivity was 1.268 whr/m2, baseline productivity = 0.993 whr/m2 and variation in daily productivity = 22.08%. The findings identified significant work environment factors and quantified their impacts on labour productivity variability in plastering activity. The results indicate that work environment factors during work in progress significantly impact the variability of labour productivity in plastering work, and ample consideration should be given to its effects.
劳动生产率的可变性是绩效的抑制因素,也是项目有效与无效的决定因素。它阻碍了工程项目的相互比较,也阻碍了工程工期和造价的准确预测。本研究选择墙面抹灰活动作为个案研究。本研究旨在量化工作环境因素对劳动生产率变异性的影响。数据收集采用直接现场观察和结构化问卷调查。结果显示,等待材料(62.4%)、工作但不工作(52.6%)和工作区域拥挤(52.5%)对劳动生产率方差均有负向影响。其他负面因素包括返工(51.7%)、等待工具/设备(51.1%)、等待信息(47.2%)和天气变化。总平均日生产率为1.268 whr/m2,基线生产率为0.993 whr/m2,日生产率变动率为22.08%。研究结果确定了重要的工作环境因素,并量化了它们对抹灰活动中劳动生产率变化的影响。结果表明,施工过程中的工作环境因素对抹灰工作中劳动生产率的变异性有显著影响,应充分考虑其影响。

The paper assessed the exhibited drivers of mentoring practices in construction professional firms in Nigeria with a view to improving the manner at which mentoring schemes are implemented in respective construction firms. Survey design was utilized in assessing the level of knowledge, mentoring concept adoption, and the exhibited drivers of mentoring relationships in these firms. Quantity surveying firms in Abuja, Nigeria were sampled through the use of structured questionnaire. Percentage, mean, one-sample t-test, and factor analyses were undertaken for the analysis of the data. The study reveals there is a good level of knowledge of mentoring concept but not so much with the adoption in the individual firms. This connote that there is a problem with the adoption of mentoring concept in construction professional firms despite knowledge of the concept by the professionals. Also, the study revealed the exhibited drivers of mentoring practices in construction professional firms. The findings show the exhibited drivers of mentoring practices in construction professional firms and recommendations were
本文评估了尼日利亚建筑专业公司指导实践的驱动因素,以改进指导计划在各自建筑公司实施的方式。采用问卷调查设计评估这些企业的知识水平、师徒关系概念的采用和展示的师徒关系驱动因素。通过使用结构化问卷对尼日利亚阿布贾的工料测量公司进行抽样调查。采用百分比、均值、单样本t检验和因子分析对数据进行分析。研究表明,企业对师徒概念的了解程度较高,但个别企业对师徒概念的接受程度不高。这意味着,尽管专业人员了解指导概念,但在建筑专业公司中采用指导概念存在问题。此外,该研究还揭示了建筑专业公司指导实践的驱动因素。研究结果表明,在建筑专业公司中,指导实践的驱动因素和建议是

Much attention has been paid to practices and methods for improving the safety management of construction projects using an incentive approach, but limited studies have been found that focus on the disincentive program, particularly in developing countries such as Indonesia. This research aims to present the findings of current practice on the disincentive program by taking into account the perceptions of Indonesian construction stakeholders. This research uses a mixed method approach through a semi-structured interview with stakeholders in the construction industry such as academics, associations & professionals, private and state-owned enterprise contractors. This research proposes a penalty in terms of the cost and duration of the suspension. Strategies for alleviating increased injuries may include training, regular communication, socialisation, education, repetitive briefing, and continuous supervision. This research indicates that laws and safety policies need to consider the costs suffered by personnel, families, and the ability of both small and large companies to manage such a disincentive program.
人们对利用激励方法改善建设项目安全管理的实践和方法给予了很大的关注,但发现对非激励方案的研究有限,特别是在印度尼西亚等发展中国家。本研究的目的是通过考虑到印尼建筑利益相关者的看法,提出目前对非激励计划的实践结果。本研究采用混合方法,通过对建筑行业的利益相关者(如学者、协会和专业人士、私营和国有企业承包商)进行半结构化访谈。这项研究提出了一个惩罚的成本和暂停的持续时间。减轻伤害增加的策略可能包括训练、定期沟通、社交、教育、重复简报和持续监督。这项研究表明,法律和安全政策需要考虑员工、家庭所承受的成本,以及小公司和大公司管理这种非激励计划的能力。
