Abstract Project management is primarily practitioner-oriented and loaded with many critical success factors (CSFs), and although these are well-evidenced in theory, they do not deliver as efficiently as factors of interest to project professionals during execution. The present study explores the perceptions of senior project managers (PMs) about project success, CSFs and complexity in large construction projects. Data from project practitioners were collected through semi-structured interviews and analysed using content analysis. The participants were selected with convenience sampling method given the complex understanding of the domain and included highly experienced PMs from the global community with expertise in project management. PMs perceive a small number of CSFs in contrast to the large exhaustive CSFs listed in the questionnaire surveys. Though important, traditional constraints of the Iron Triangle are considered inadequate in defining project success. Project professionals are seen as relying more on other performance indicators for defining a project as a success. They perceive complex construction projects in terms of a large number of interfaces, complex working systems and uncertainty. The findings of this paper suggest that project practitioners perceive differently about the CSFs and project success.
摘要项目管理主要以从业者为导向,并包含许多关键的成功因素(CSF),尽管这些因素在理论上得到了很好的证明,但在执行过程中,它们并不像项目专业人员感兴趣的因素那样有效。本研究探讨了高级项目经理(PM)对大型建筑项目中项目成功、CSF和复杂性的看法。通过半结构化访谈收集项目从业者的数据,并使用内容分析进行分析。鉴于对该领域的复杂理解,参与者采用方便的抽样方法进行选择,其中包括来自全球社区的具有项目管理专业知识的经验丰富的PM。与问卷调查中列出的大量详尽的CSF相比,PM认为CSF数量较少。尽管很重要,但铁三角的传统约束被认为不足以定义项目的成功。项目专业人员被视为更多地依赖其他绩效指标来定义项目的成功。他们从大量的接口、复杂的工作系统和不确定性的角度来看待复杂的建设项目。本文的研究结果表明,项目从业者对CSF和项目成功的看法不同。

Exploring the social legitimacy of urban road PPPs in Nigeria 探讨尼日利亚城市道路ppp的社会合法性

Abstract Public–private partnerships (PPPs) have become an effective and efficient contractual agreement between the state and the private sector for providing infrastructure services. Yet, their social acceptance and legitimacy are questionable. Communities accept such changes to their social contract with the government only if the PPPs are perceived to be legitimate as public institutions are not trusted by the communities. As a result, the disappointments and controversial underperformance of PPPs in Nigeria, like most developing countries, have been generally associated with community opposition due to any agency or competence-related failure. Hence, the need for this study. Drawing on data from two urban road PPPs in Nigeria, we identify the following three deeply internalised shared beliefs that shape a community group’s perceptions and attitudes towards an infrastructure built by PPPs in their neighbourhood: the public services should be provided for free, PPPs are created mainly to serve perceived ‘corrupt’ politicians and public institutions are not effective and efficient in service delivery. These beliefs, combined with the community’s structural power, explain why some community groups oppose (or support) infrastructure PPPs within their proximity, and the growing legitimacy challenge PPPs face. Our paper in this regard provides a guidance for designing effective and targeted community engagement strategies for PPP projects and contributed to PPP stakeholder management and mainstream stakeholder management research.
公私合作伙伴关系(ppp)已经成为国家和私营部门之间提供基础设施服务的有效和高效的合同协议。然而,他们的社会接受度和合法性是值得怀疑的。只有当公私合作被认为是合法的,因为公共机构不受社区信任时,社区才会接受这种与政府社会契约的变化。因此,与大多数发展中国家一样,尼日利亚公私合作伙伴关系的令人失望和有争议的表现不佳通常与社区反对有关,因为任何机构或能力相关的失败。因此,有必要进行这项研究。根据尼日利亚两个城市道路公私合作项目的数据,我们确定了以下三个根深蒂固的共同信念,这些信念塑造了社区群体对公私合作项目在其社区建设的基础设施的看法和态度:公共服务应该免费提供,公私合作项目主要是为了服务于被认为是“腐败”的政客,以及公共机构在提供服务方面效率低下。这些信念与社区的结构性力量相结合,解释了为什么一些社区团体反对(或支持)他们附近的基础设施ppp,以及ppp面临的日益增长的合法性挑战。本文为PPP项目设计有效、有针对性的社区参与策略提供了指导,为PPP利益相关者管理和主流利益相关者管理研究做出了贡献。

Real-estate price prediction with deep neural network and principal component analysis 基于深度神经网络和主成分分析的房地产价格预测

Abstract Despite the wide application of deep neural networks (DNN) models, their application over small-sized real-estate price prediction is limited due to the reduced prediction accuracy and the high-dimensionality of the dataset. This study motivates small-sized real-estate agencies to take DNN-driven decisions using the available local dataset. To improve the high-dimensionality of real-estate price datasets and thus enhance the price-prediction accuracy of a DNN model, this paper adopts principal component analysis (PCA). The PCA benefits in improving the prediction accuracy of a DNN model are threefold: dimensionality reduction, dataset transformation and localisation of influential price features. The results indicate that, through the PCA-DNN model, the transformed dataset achieves higher accuracy (90%–95%) and better generalisation ability compared with other benchmark price predictors. The spatial and building age proved to have the most impact in determining the overall real-estate price. The application of PCA not only reduces the high-dimensionality of the dataset but also enhances the quality of the encoded feature attributes. The model is beneficial in real-estate and construction applications, where the absence of medium and big datasets decreases the price-prediction accuracy.
摘要尽管深度神经网络(DNN)模型应用广泛,但由于预测精度低和数据集维数高,其在小型房地产价格预测中的应用受到限制。这项研究促使小型房地产中介机构利用可用的本地数据集做出DNN驱动的决策。为了提高房地产价格数据集的高维性,从而提高DNN模型的价格预测精度,本文采用了主成分分析(PCA)。PCA在提高DNN模型预测精度方面有三个好处:降维、数据集转换和有影响力的价格特征的本地化。结果表明,通过PCA-DNN模型,与其他基准价格预测因子相比,转换后的数据集实现了更高的准确性(90%-95%)和更好的泛化能力。事实证明,空间和建筑年代对决定整体房地产价格的影响最大。PCA的应用不仅降低了数据集的高维性,而且提高了编码特征属性的质量。该模型在房地产和建筑应用中是有益的,因为缺乏中大型数据集会降低价格预测的准确性。

Abstract The article is devoted to the development of a new information and communication concept – “construction management template (CMT)”. This concept changes the way knowledge management in construction is due to: taking into account the most effective modern and traditional methods of management; use of information technologies; end-to-end integration of different solutions into one information and communication tool. CMT is an information and communication model in the form of a three-dimensional parametric part of a building or structure and the associated resource schedule of works used to plan and control management, architectural, technological, operational, and economic decisions throughout the construction project. Combining different construction solutions and including management innovations, the developed information and communication concept is the latest way to manage knowledge in construction. Development of the information and communication concept CMT takes into account the use of modern software, innovative and most effective traditional methods of managing enterprises of the full investment construction cycle. The practical significance of the results lies in the development of recommendations for: finding and using efficiency reserves in construction management with the help of modern information technologies; development and use of construction management templates for knowledge management. The obtained results allowed establishing the new method of management in construction increases the accuracy and speed of management influences, while reducing the cost of management. Thus, more sustainable development of construction entrepreneurship is possible.
摘要本文提出了一种新的信息传播理念——“施工管理模板(CMT)”。这一理念改变了知识管理在建设中的方式,原因在于:兼顾了现代和传统最有效的管理方法;使用资讯科技;将不同的解决方案端到端集成到一个信息和通信工具中。CMT是一种信息和通信模型,以建筑或结构的三维参数部分和相关的工程资源时间表的形式,用于规划和控制整个建设项目的管理、建筑、技术、运营和经济决策。结合不同的施工解决方案,包括管理创新,开发的信息和通信概念是管理施工知识的最新方式。CMT发展的信息通信理念兼顾了利用现代软件,创新和最有效的传统方法管理企业的全投资建设周期。研究结果的现实意义在于:在现代信息技术的帮助下,在施工管理中发现和利用效率储备;开发和使用施工管理模板进行知识管理。所得结果使建立新的施工管理方法对提高管理的准确性和速度产生影响,同时降低管理成本。从而使建筑企业的可持续发展成为可能。

Abstract In the face of several uncertainties in the construction industry, conflicts and disputes seem inevitable. The aim of this systematic literature review of methodologies for prevention and resolution of conflicts was to develop an updated guidance for conflict management in the construction industry. To achieve this, we developed a novel tool termed Modified Reporting Items for Structured Reviews in Engineering and Technology (MORISE) that considered a modified tool from the original literature review method Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Three databases, ScienceDirect, Scopus, and American Society for Civil Engineers (ASCE), were searched and 61 articles were shortlisted. In terms of frequency of reasons cited as causes for disputes, payment regimes and delays rank first, followed by written agreement interpretation and changes in projects. Acceptable approaches to resolution of disputes include negotiation, arbitration, facilitation, and dispute resolution boards. This study were able to make a clear distinction between methodologies adopted by various researchers for the prevention and resolution of conflicts and show that in addition to prevention of conflicts, there are comprehensive and suitable techniques to resolve conflicts, which can be adopted in practice.
面对建筑行业的诸多不确定性,矛盾和纠纷似乎不可避免。对预防和解决冲突的方法进行系统的文献综述的目的是为建筑行业的冲突管理制定最新的指导方针。为了实现这一目标,我们开发了一种新的工具,称为工程和技术结构化评论的修改报告项目(MORISE),它考虑了原始文献综述方法的修改工具,即系统评论和荟萃分析的首选报告项目(PRISMA)。检索了三个数据库:ScienceDirect、Scopus和美国土木工程师学会(ASCE),最终有61篇文章入围。就引发纠纷的原因频率而言,付款制度和延误排在第一位,其次是书面协议解释和项目变更。可接受的解决争议的方法包括谈判、仲裁、调解和争议解决委员会。本研究能够明确区分不同研究者在预防和解决冲突方面所采用的方法,并表明除了预防冲突之外,还有全面而合适的解决冲突的技术,这些技术可以在实践中采用。

Abstract The study investigated the impact of the high volume of vehicular traffic on pilgrims and the community during the Zion Christian Church Easter weekend pilgrimage. The findings indicate that the South African transport planning approach is ossified and divorced from reality. There is a lacuna to address peak traffic challenges during the Easter weekend and the festive season. Notably, the government-led seasonal road safety campaigns, such as “Arrive Alive”, are curiously inadequate to address peak traffic and road accidents challenges in South Africa. The study employed the action research approach by collaborating with the Polokwane Local Municipality (PLM) to come up with lasting solutions to traffic congestion during the Easter weekend. The study found that the vehicular mode of transport was inadequate to cater for the mobility of pilgrims as well as other motorists during Easter weekend. The transport management framework for the PLM and a peak traffic standard were developed as part of the study recommendations. These recommendations augur a shift to transport planning in South Africa.
摘要本研究调查了锡安基督教会复活节周末朝圣期间大量车辆交通对朝圣者和社区的影响。研究结果表明,南非的交通规划方法僵化且脱离现实。在复活节周末和节日期间,应对高峰交通挑战存在漏洞。值得注意的是,政府领导的季节性道路安全运动,如“活着到达”,奇怪地不足以应对南非的高峰交通和道路事故挑战。这项研究采用了行动研究的方法,与波洛克瓦内地方市政当局(PLM)合作,为复活节周末的交通拥堵提出了持久的解决方案。研究发现,复活节周末期间,车辆交通方式不足以满足朝圣者和其他驾车者的出行需求。PLM的交通管理框架和高峰交通标准是作为研究建议的一部分制定的。这些建议预示着南非交通规划的转变。

Parsimonious process model of energy retrofit of buildings 建筑节能改造的简约过程模型

Abstract Building information modelling (BIM) technology has been focusing on the creation, sharing and use of a comprehensive digital twin of the facility under construction or renovation. It is believed that a more comprehensive, structured and complete model would be better. The aim of this paper and the underlying research is to reaffirm the view that the essence of information is to inform the user and that the main purpose of information models is that they are informative – that they contain the necessary information. Parsimonious information is information that is necessary but as simple as possible. Our hypothesis is that in many cases simpler models could be more useful, as they do not introduce technological barriers with the usually involved low- and medium-level contractors. One such case is the energy retrofitting of existing buildings. Many public and residential buildings with poor energy performance are located all over the world, especially in Eastern and Central Europe, as well as in China. They are an efficient target for a significant improvement in their energy performance by improving the building envelope and openings. The paper presents an economical process model for the modernisation of existing buildings. This model provides a basis for a parsimonious product model, which is currently under development. The broader objective of the research presented is to examine cases where a heavy information model may not be necessary and where a detailed process definition – as described in the BIM implementation plan and related documents – would lead to over-specification that would limit the free dynamics of a workflow.
建筑信息模型(BIM)技术一直专注于创建、共享和使用正在建设或翻新的设施的综合数字孪生体。相信一个更全面、更有结构、更完整的模型会更好。本文和基础研究的目的是重申这样一种观点,即信息的本质是告知用户,信息模型的主要目的是提供信息——它们包含必要的信息。简约信息是必要的信息,但要尽可能简单。我们的假设是,在许多情况下,更简单的模型可能更有用,因为它们不会引入通常涉及的中低级别承包商的技术壁垒。其中一个例子就是对现有建筑进行节能改造。世界各地都有许多能效较差的公共建筑和住宅建筑,特别是在东欧和中欧,以及在中国。它们是通过改善建筑围护结构和开口来显著改善其能源性能的有效目标。本文提出了现有建筑现代化的经济过程模型。该模型为目前正在开发的简约产品模型提供了基础。本研究提出的更广泛的目标是检查在哪些情况下可能不需要大量的信息模型,以及在哪些情况下详细的过程定义(如BIM实施计划和相关文档中所描述的)会导致过度规范,从而限制工作流的自由动态。

Abstract Poor quality occurs in >80% of building projects. They can increase the cost of a building by up to 50% and can delay a project by up to 50%. This research investigated the determinants of poor quality on building on-sites. The research developed a questionnaire instrument that included 20 determinants of poor-quality buildings on construction sites based on literature and site visits. The survey forms were administered to construction sites operatives through hand delivery. A total of 80% of the respondents measured that the poor quality of buildings was caused by the 20 determinants. Poor workmanship, non-compliance with requirements/standards, inadequate site management, failure to achieve high-quality standards, and poor-quality materials/components were the major determinants of the poor quality of buildings during construction. This research provides fresh information on the causes and impact of poor quality on the performance of the building sector.
摘要80%以上的建筑工程质量较差。它们可以使建筑成本增加50%,也可以使项目延迟50%。这项研究调查了现场建筑质量差的决定因素。该研究开发了一个问卷工具,根据文献和实地考察,其中包括建筑工地上劣质建筑的20个决定因素。调查表格是透过专人递送的方式交予建筑地盘人员。共有80%的受访者认为,建筑质量差是由20个决定因素造成的。工艺差、不符合要求/标准、现场管理不足、未能达到高质量标准以及材料/部件质量差是建筑施工期间质量差的主要决定因素。这项研究提供了关于建筑行业质量差的原因和影响的新信息。

Abstract The public sector in Germany lags behind the economy in terms of projectification, i.e., the prevalence of projects and experience in applying project management. This has significant implications for realizing complex infrastructure projects in which the public sector is involved as one of the main actors. Nowadays, projectification represents a particular way of thinking about how to embrace a series of dynamic and challenging changes, design them, and implement them effectively for the benefit of society. A quantitative study of projectification in society in Germany was the starting point for our research, the results of which we compared with data from earlier studies of projectification in the economy. Using an interpretative case study drawing on insights from the Berlin Airport, we analyzed the impact of lagging projectification in the public sector in Germany on realizing infrastructure projects to propose suitable approaches. The results of this case study reveal significant effects of lagging projectification in the public sector of Germany on realizing infrastructure projects. In the case of the Berlin BER Airport, an inadequate governance system led to a 9-year delay in the completion date and a 250% overrun of costs directly attributable to the project. This could have been avoided by involving the private construction industry more collaboratively, by building on previous experiences gained, and by a more cooperative way of project planning and implementation. To guide future research, hypotheses are derived that can be used to analyze the underlying problem in greater depth and to derive recommendations for action.
摘要德国公共部门在项目化方面落后于经济,即项目的普及率和应用项目管理的经验。这对实现公共部门作为主要行动者之一参与的复杂基础设施项目具有重大影响。如今,项目化代表了一种特殊的思维方式,即如何接受一系列动态和具有挑战性的变化,设计并有效实施这些变化,以造福社会。对德国社会项目化的定量研究是我们研究的起点,我们将研究结果与早期经济项目化研究的数据进行了比较。利用柏林机场的解释性案例研究,我们分析了德国公共部门项目化滞后对实现基础设施项目的影响,以提出合适的方法。该案例研究的结果揭示了德国公共部门项目化滞后对基础设施项目实现的显著影响。就柏林BER机场而言,治理系统不足导致竣工日期延迟了9年,直接归因于该项目的成本超支了250%。通过让私营建筑业更加合作,在以往经验的基础上再接再厉,以及通过项目规划和实施的更加合作的方式,本可以避免这种情况。为了指导未来的研究,我们提出了一些假设,这些假设可用于更深入地分析潜在问题,并提出行动建议。

Abstract This study examines the capability improvement measures of the public sector client for enhancing the implementation of building information modeling (BIM) in construction project delivery. The study adopted a quantitative descriptive analysis based on primary data obtained through a structured questionnaire. A total of 198 valid questionnaires obtained from construction professionals within public sector organizations in Lagos State, Nigeria, provided primary quantitative data for the assessment. Data collected were analyzed using descriptive and inferential statistics. The findings indicated the measures to enhance the capacity of the public sector for BIM implementation including the following: team-based structure and recruitment of adequate number of staff (with mean score [MS] = 3.66), government support and involvement (MS = 3.64), government policies, adoption of process open to innovation, and investment in equipment and technology (MS = 3.60) had been considerably entrenched. However, measures that resulted in improved efficiency were limited to the following: reward system for performance (MS = 3.81), government policies, and education and training of staff (MS = 3.74), government support and involvement (MS = 3.73), and clear job description (MS = 3.71). Most of the measures with high level of impact were not necessarily those that are frequently used. On this basis, the public sector needs to differ from the status quo by adopting improvement measures that are appropriate for enhancing its capabilities for BIM in project delivery. The findings indicate implications that could enable the public sector to adjust and make necessary policies in a bid to improve BIM implementation in project delivery.
摘要本研究考察了公共部门客户在建设项目交付中加强建筑信息建模(BIM)实施的能力改进措施。该研究采用了定量描述性分析,基于通过结构化问卷获得的原始数据。从尼日利亚拉各斯州公共部门组织的建筑专业人员那里获得的198份有效问卷为评估提供了初步的定量数据。使用描述性和推断统计学对收集的数据进行分析。研究结果表明,提高公共部门BIM实施能力的措施包括:基于团队的结构和招聘足够数量的员工(平均得分[MS]=3.66)、政府支持和参与(MS=3.64)、政府政策、采用开放式创新流程、,对设备和技术的投资(MS=3.60)已经相当稳固。然而,提高效率的措施仅限于以下方面:绩效奖励制度(MS=3.81)、政府政策、员工教育和培训(MS=3.74)、政府支持和参与(MS=3.33)以及明确的工作描述(MS=3.75)。大多数影响程度高的措施不一定是经常使用的措施。在此基础上,公共部门需要与现状不同,采取适当的改进措施,以提高其在项目交付中的BIM能力。研究结果表明,公共部门可以调整并制定必要的政策,以改善BIM在项目交付中的实施。
