PurposeThe construction industry has considerably evolved in the recent two decades due to the emergence of sustainability, lean construction (LC) and building information modelling (BIM). Despite previous research efforts, there is still a gap concerning the multidimensional nature of their integration. Hence, this study aims to fill the mentioned knowledge gap through exploring and comparing the challenges, enablers, techniques as well as benefits of integrating LC with BIM and sustainability in building construction projects.Design/methodology/approachA systematic literature review was conducted to fulfill the purpose of this study.FindingsThe findings reveal and compare the challenges, enablers, techniques and benefits of integrating LC with BIM and sustainability in building construction projects. The results suggest that there are eight common challenges for integrating LC with BIM and sustainability, including high initial cost, lack of collaboration, lack of professionals and lack of compatible contractual framework. The discovered challenges, enablers, techniques and benefits seem to be mostly routed in people. The findings also suggest that the synergistic benefits of integrating LC with BIM and sustainability can overcome the common challenges (safety, reliability, productivity, collaboration and quality) in construction projects.Originality/valueThe findings contribute to the literature and practice concerning the integration of LC with BIM and sustainability by exploring, comparing and discussing the relevant challenges, enablers, techniques as well as benefits. Moreover, the findings reveal the significance of the development of people in construction industry, besides processes and technology, as people are always subject of activities in construction while processes and technology are always objects.
目的由于可持续性、精益施工(LC)和建筑信息建模(BIM)的出现,建筑业在近二十年中发生了长足的发展。尽管之前进行了研究,但在它们融合的多层面性质方面仍然存在差距。因此,本研究旨在通过探索和比较LC与BIM集成的挑战、促成因素、技术以及好处,以及建筑施工项目中的可持续性,填补上述知识空白。设计/方法/方法为了实现本研究的目的,进行了系统的文献综述。发现这些发现揭示并比较了将LC与BIM以及建筑施工项目中的可持续性相结合的挑战、促成因素、技术和好处。研究结果表明,将LC与BIM和可持续性相结合存在八个常见挑战,包括高昂的初始成本、缺乏合作、缺乏专业人员和缺乏兼容的合同框架。发现的挑战、促成因素、技术和好处似乎大多来自于人。研究结果还表明,将LC与BIM和可持续性相结合的协同效益可以克服建筑项目中的常见挑战(安全、可靠性、生产力、协作和质量)。独创性/价值研究结果通过探索、比较和讨论相关挑战、促成因素、技术和好处,为LC与BIM的整合和可持续性的文献和实践做出了贡献。此外,研究结果揭示了建筑业中人的发展除了过程和技术之外的意义,因为人始终是建筑活动的主体,而过程和技术始终是对象。

PurposeThe purpose of this paper is to use Delphi technique to assess the applicability of coupling various project delivery methods (PDMs) and contract strategies (CSs) for delivery of public building projects (PBP) in Ethiopia.Design/methodology/approachTo achieve the objective of this research, an online Delphi study was designed, conducted and analyzed using various statistical procedures. Results were compared to CII’s project delivery and CS (PDCS) tool, a US-based PDM selection tool.FindingsThis study converged in the third round signifying a consensus on the importance of design–build and construction manager at risk as alternatives to design–bid–build. In addition, “controlling schedule growth” was deemed to be a major performance measure that needs to be considered for PBP in Ethiopia, a result consistent with the outcomes from CII’s PDCS tool.Originality/valueAmong existing studies, none to the best of the authors’ knowledge has focused on a holistic approach to identify the most appropriate pairings of PDMs and CSs for PBP which was critically needed due to the magnitude and high stakes of these projects. This research is a steppingstone toward gaining knowledge on how to approach these types of projects in fast-growing environments thirsty for new building projects such as in Ethiopia.
本文的目的是使用德尔菲技术来评估埃塞俄比亚公共建筑项目(PBP)交付中耦合各种项目交付方法(pdm)和合同策略(CSs)的适用性。设计/方法学/方法为了实现本研究的目的,设计了一项在线德尔菲研究,并使用各种统计程序进行了分析。将结果与CII的项目交付和CS (PDCS)工具(一种基于美国的PDM选择工具)进行比较。本研究在第三轮得出结论,标志着对设计-建造和施工管理风险的重要性达成共识,作为设计-投标-建造的替代方案。此外,“控制进度增长”被认为是埃塞俄比亚PBP需要考虑的主要绩效指标,这一结果与CII的PDCS工具的结果一致。原创性/价值在现有的研究中,据作者所知,没有一个研究集中在一个整体的方法上,以确定PBP中最合适的pdm和CSs配对,由于这些项目的规模和高风险,这是非常需要的。这项研究是获得如何在埃塞俄比亚等急需新建筑项目的快速增长环境中处理这些类型项目的知识的踏脚石。

PurposeThis study aims to demonstrate how the process of quality function deployment (QFD) is used to identify the basic requirements of the customers in designing and executing the commercial business center.Design/methodology/approachThis study was considered with the aim of determining the approach of QFD methodology used in the planning and designing of commercial business centers. The methodology used in the study is a customer-driven process that includes customer requirements in each and every aspect of the planning and designing of the project. The main focus of this study is to understand the requirements of the customers and to design and execute a commercial business project.FindingsThis study illustrates the quality requirements of the projects that benefit from the QFD process to obtain customer requirements for the planning and designing of commercial business centers. A case study is used to demonstrate the use of QFD process. This helps to explain the effective application of QFD in the planning and designing of business centers and similar constructions.Research limitations/implicationsThe planning and designing of the commercial business center using the QFD process were challenging and hence it is limited to the design part. The strategic objectives are not taken into account while performing QFD in this case study and the risk of market research is lacking. House of quality (HOQ) can be too complicated at times; hence, the adaptability in the traditional QFD is lacking. Most of the work in the HOQ matrix is done through subjective evaluation. Therefore, this research is mostly useful for a single party responsible for all phases of the planning and designing of the project.Originality/valueIn the construction industry, the use of the QFD process for project performance analysis and application is restricted. As a result of the scarcity of studies on the planning and design of construction projects, this study on the planning and design of a construction project was inspired.
目的本研究旨在探讨在商业商务中心的设计与执行中,如何运用品质功能展开(QFD)的过程来辨识顾客的基本需求。设计/方法/方法本研究的目的是确定在商业商业中心的规划和设计中使用的QFD方法。研究中使用的方法是客户驱动的过程,包括项目规划和设计的每个方面的客户需求。本研究的主要重点是了解客户的需求,并设计和执行商业业务项目。本研究阐明了受益于QFD过程的项目的质量需求,以获得商业商业中心规划和设计的客户需求。案例研究用于演示QFD过程的使用。这有助于解释QFD在商业中心和类似建筑的规划设计中的有效应用。研究局限/启示使用QFD过程规划和设计商业商业中心是具有挑战性的,因此它仅限于设计部分。在本案例研究中,在执行QFD时没有考虑到战略目标,并且缺乏市场研究的风险。质量屋(HOQ)有时可能过于复杂;因此,传统的QFD缺乏适应性。HOQ矩阵中的大部分工作都是通过主观评价完成的。因此,这项研究主要是对负责项目规划和设计的所有阶段的单一方有用。独创性/价值在建筑行业,使用QFD过程进行项目绩效分析和应用是受到限制的。由于对建设项目规划设计的研究较少,本研究受到了对某建设项目规划设计的启发。

PurposeThis study aims to identify and evaluate the key strategies to promote the implementation of automation techniques with reference to the Nigerian construction industry.Design/methodology/approachPragmatic philosophical thinking using a mixed-method approach (a combination of qualitative and quantitative) was adopted for this study. The qualitative strand of this research was achieved using a Delphi technique while a well-structured questionnaire conducted among 191 construction professionals was adopted to attain the quantitative strand. Obtained data were analyzed using frequencies, percentages, mean item scores, Kruskal–Wallis H test and exploratory factor analysis (FA).FindingsResults revealed that the “provision of funding and subsidies for automation techniques” “mandatory automation policies and regulations,” “creating incentives for adoption,” “formulation of programs to promote awareness” and “deploying gamification to boost employee performance” were the top five strategies to promote the adoption of automation techniques. FA revealed four principal clusters, namely, awareness and publicity programs, government regulations and standards, provision of education and training and awards and recognition.Practical implicationsThis study provided a solid theoretical and empirical foundation that can be useful to construction industry stakeholders, decision-makers, policymakers and the government in mapping out strategies to promote the incorporation and deployment of automation and robotics in the construction industry.Originality/valueTo the best of the authors’ knowledge, this study is one of the first in developing countries and Nigeria to establish an ordered grouping structure of the strategies to promote the adoption of automation techniques.

PurposeThe purpose of this study is to describe latent classes explaining the innovation logic in the Finnish construction companies. Innovativeness is a driver of competitive performance and vital to the long-term success of any organisation and company.Design/methodology/approachUsing finite mixture structural equation modelling (FMSEM), the authors have classified innovation logic into latent classes. The method analyses and recognises classes for companies that have similar logic in innovation activities based on the collected data.FindingsThrough FMSEM analysis, the authors have identified three latent classes that explain the innovation logic in the Finnish construction companies – LC1: the internal innovators; LC2: the non-innovation-oriented introverts; and LC3: the innovation-oriented extroverts. These three latent classes clearly capture the perceptions within the industry as well as the different characteristics and variables.Research limitations/implicationsThe presented latent classes explain innovation logic but is limited to analysing Finnish companies. Also, the research is quantitative by nature and does not increase the understanding in the same manner as qualitative research might capture on more specific aspects.Practical implicationsThis paper presents starting points for construction industry companies to intensify innovation activities. It may also indicate more fundamental changes for the structure of construction industry organisations, especially by enabling innovation friendly culture.Originality/valueThis study describes innovation logic in Finnish construction companies through three models (LC1–LC3) by using quantitative data analysed with the FMSEM method. The fundamental innovation challenges in the Finnish construction companies are clarified via the identified latent classes.
目的本研究的目的是描述芬兰建筑公司中解释创新逻辑的潜在类别。创新是竞争绩效的驱动力,对任何组织和公司的长期成功都至关重要。设计/方法论/方法利用有限混合结构方程建模(FMSEM),作者将创新逻辑分为潜在类。该方法根据收集的数据分析和识别在创新活动中具有类似逻辑的公司的类别。通过FMSEM分析,作者确定了三个潜在的类别来解释芬兰建筑公司的创新逻辑——LC1:内部创新者;LC2:非创新型内向者;LC3:创新导向型外向型。这三个潜在类别清楚地反映了行业内的看法以及不同的特征和变量。研究局限性/含义所介绍的潜在类别解释了创新逻辑,但仅限于分析芬兰公司。此外,该研究本质上是定量的,并没有像定性研究可能捕捉到的更具体方面那样增加理解。实践意义本文提出了建筑业企业加强创新活动的出发点。它还可能表明建筑业组织结构发生了更根本的变化,特别是通过创造有利于创新的文化。独创性/价值本研究采用FMSEM方法分析的定量数据,通过三个模型(LC1–LC3)描述了芬兰建筑公司的创新逻辑。芬兰建筑公司面临的基本创新挑战通过确定的潜在类别得到了澄清。

PurposeThis study aims to focus on sustainable supplier selection in a construction company considering a new multi-criteria decision-making (MCDM) method based on dominance-based rough set analysis. The inclusion of sustainability concept in industrial supply chains has started gaining momentum due to increased environmental protection awareness and social obligations. The selection of sustainable suppliers marks the first step toward accomplishing this objective. The problem of selecting the right suppliers fulfilling the sustainable requirements is a major MCDM problem since various conflicting factors are underplay in the selection process. The decision-makers are often confronted with inconsistent situations forcing them to make imprecise and vague decisions.Design/methodology/approachThis paper presents a new method based on dominance-based rough sets for the selection of right suppliers based on sustainable performance criteria relying on the triple bottom line approach. The method applied has its distinct advantages by providing more transparency in dealing with the preference information provided by the decision-makers and is thus found to be more intuitive and appealing as a performance measurement tool.FindingsThe technique is easy to apply using “jrank” software package and devises results in the form of decision rules and ranking that further assist the decision-makers in making an informed decision that increases credibility in the decision-making process.Originality/valueThe novelty of this study of its kind is that uses the dominance-based rough set approach for a sustainable supplier selection process.
目的本研究旨在研究建筑公司的可持续供应商选择,考虑一种基于优势粗糙集分析的新的多准则决策方法。由于环境保护意识和社会义务的提高,将可持续性概念纳入工业供应链的势头开始增强。选择可持续的供应商标志着朝着实现这一目标迈出了第一步。选择满足可持续要求的合适供应商是MCDM的一个主要问题,因为在选择过程中,各种冲突因素都被低估了。决策者经常面临不一致的情况,迫使他们做出不精确和模糊的决定。设计/方法论/方法本文提出了一种基于优势粗糙集的新方法,用于基于三重底线方法的可持续绩效标准选择合适的供应商。所应用的方法具有其独特的优势,因为它在处理决策者提供的偏好信息时提供了更多的透明度,因此被发现作为一种绩效衡量工具更直观、更具吸引力。发现使用“jrank”软件包很容易应用该技术,并以决策规则和排名的形式设计结果,进一步帮助决策者做出明智的决策,从而提高决策过程的可信度。原创性/价值这类研究的新颖之处在于,将基于优势的粗糙集方法用于可持续的供应商选择过程。

PurposeWindow shading has always been an effective technique to control the access of solar radiation; however, inappropriate selection of the shading technique, location and optical properties may lead to an increase in energy consumed for cooling and artificial lighting. Venetian blinds (VBs) are a type of adjustable shading devices that can be installed to the interior, exterior or in between glass panes of a window and that can be easily implemented in both new and existing buildings. This study aims to investigate the impact of three VB parameters: slat angle, reflectivity and location on the overall energy consumption of a residential space with a south-facing facade under the hot arid desert climate of Saudi Arabia’s capital, Riyadh. For the purpose of globalizing the findings, the same investigations were applied for two other cities of similar climates: Cairo, Egypt, and Arizona, the USA.Design/methodology/approachA test room was modelled for energy simulation, with a 20% window-to-wall ratio. A VB was assigned with alternatives of being located to the indoor, outdoor or in between double glass panes. High, medium and low reflectivity values were applied at each location at slat angle alternatives of 15°, 30°, 45°, 60°, 75° and 90°.FindingsResults showed VB performance across slat angles, where up to 20.1% energy savings were achieved by mid-pane high reflectivity VBs in Riyadh, while the value exceeded 30% in case of being externally located. A similar performance pattern occurred in the other two cities of hot arid desert climates: Cairo and Arizona.Research limitations/implicationsThe study is limited to VBs at a fixed position, with no upward movement for partial or full openness conditions. The effect of blind control and operation on performance, such as the amount and duration of openness/closure of the blind and changes in slat angle across time, in addition to VB automation, shall be investigated in a future study.Practical implicationsThe better understanding of VB energy performance achieved would enhance a more rational selection of VBs, which would benefit the construction industry as it would assist designers, real estate developer companies, as well as end-users in the decision-making process and help to realize energy-efficient solutions in residential buildings. VB production entities would also benefit by manufacturing and promoting for energy-efficient products.Originality/valueIn this study, a matrix of combinations of three VB parameters was developed, and the effect of these combinations on the overall energy consumption of both artificial lighting and heating, ventilation and air conditioning (HVAC) systems was evaluated and compared to identify the combinations of higher efficiency. The literature showed that these three parameters were hardly investigated in a combined form and hardly assessed by considering the overall energy consumed by both artificial lighting and HVAC.
目的窗户遮光一直是控制太阳辐射进入的有效技术;然而,遮光技术、位置和光学特性的不适当选择可能导致冷却和人工照明所消耗的能量增加。百叶窗(VBs)是一种可调节的遮阳装置,可以安装在窗户的内部、外部或玻璃板之间,并且可以在新建筑和现有建筑中轻松实施。本研究旨在调查在沙特阿拉伯首都利雅得炎热干旱的沙漠气候下,百叶窗角度、反射率和位置三个VB参数对朝南立面住宅空间整体能耗的影响。为了使研究结果全球化,对另外两个气候相似的城市进行了同样的调查:埃及开罗和美国亚利桑那州。设计/方法/方法为能源模拟建模了一个试验室,窗墙比为20%。VB被分配到室内、室外或双层玻璃之间的替代位置。在15°、30°、45°、60°、75°和90°的缝翼角备选方案下,在每个位置应用高、中、低反射率值。结果显示,VB在缝翼角上的性能,其中利雅得的中窗格高反射率VBs可实现高达20.1%的节能,而位于外部的情况下,该值超过30%。类似的表现模式出现在其他两个炎热干旱沙漠气候的城市:开罗和亚利桑那州。研究局限性/含义该研究仅限于固定位置的VBs,在部分或完全开放的条件下没有向上移动。百叶窗控制和操作对性能的影响,如百叶窗打开/关闭的数量和持续时间,以及百叶窗角度随时间的变化,以及VB自动化,应在未来的研究中进行研究。实际意义更好地了解VB的能源性能将有助于更合理地选择VB,这将有利于建筑业,因为它将帮助设计师、房地产开发商公司以及最终用户参与决策过程,并有助于在住宅建筑中实现节能解决方案。VB生产实体也将受益于生产和推广节能产品。独创性/价值在本研究中,开发了三个VB参数的组合矩阵,并评估和比较了这些组合对人工照明和供暖、通风和空调(HVAC)系统整体能耗的影响,以确定效率更高的组合。文献表明,这三个参数很难以组合的形式进行研究,也很难通过考虑人工照明和暖通空调消耗的总能量进行评估。

PurposeThis paper aims to identify modern construction techniques for affordable housing, such as prefabrication and interlocking systems, that can save time and cost while also providing long-term sustainable benefits that are desperately needed in today's construction industry.Design/methodology/approachThe need for housing is growing worldwide, but traditional construction cannot cater to the demand due to insufficient time. There should be some paradigm shift in the construction industry to supply housing to society. This paper presented a state-of-the-art review of modern construction techniques practiced worldwide and their advantages in affordable housing construction by conducting a systematic literature review and applying the backward snowball technique. The paper reviews modern prefabrication techniques and interlocking systems such as modular construction, formwork systems, light gauge steel/cold form steel construction and sandwich panel construction, which have been globally well practiced. It was understood from the overview that modular construction, including modular steel construction and precast concrete construction, could reduce time and costs efficiently. Further enhancement in the quality was also noticed. Besides, it was observed that light gauge steel construction is a modern phase of steel that eases construction execution efficiently. Modern formwork systems such as Mivan (Aluminium Formwork) have been reported for their minimum construction time, which leads to faster construction than traditional formwork. However, the cost is subjected to the repetitions of the formwork.

Industrialized house building productivity growth 工业化房屋建筑生产力增长
IF 3.3 Q2 CONSTRUCTION & BUILDING TECHNOLOGY Pub Date : 2023-05-03 DOI: 10.1108/ci-04-2022-0097
L. Stehn, A. Jiménez
PurposeThe purpose of this paper is to understand if and how industrialized house building (IHB) could support productivity developments for housebuilding on project and industry levels. The take is that fragmentation of construction is one explanation for the lack of productivity growth, and that IHB could be an integrating method of overcoming horizontal and vertical fragmentation.Design/methodology/approachSinge-factor productivity measures are calculated based on data reported by IHB companies and compared to official produced and published research data. The survey covers the years 2013–2020 for IHB companies building multi-storey houses in timber. Generalization is sought through descriptive statistics by contrasting the data samples to the used means to control vertical and horizontal fragmentation formulated as three theoretical propositions.FindingsAccording to the results, IHB in timber is on average more productive than conventional housebuilding at the company level, project level, in absolute and in growth terms over the eight-year period. On the company level, the labour productivity was on average 10% higher for IHB compared to general construction and positioned between general construction and general manufacturing. On the project level, IHB displayed an average cost productivity growth of 19% for an employed prefabrication degree of about 45%.Originality/valueEmpirical evidence is presented quantifying so far perceived advantages of IHB. By providing analysis of actual cost and project data derived from IHB companies, the article quantifies previous research that IHB is not only about prefabrication. The observed positive productivity growth in relation to the employed prefabrication degree indicates that off-site production is not a sufficient mean for reaching high productivity and productivity growth. Instead, the capabilities to integrate the operative logic of conventional housebuilding together with logic of IHB platform development and use is a probable explanation of the observed positive productivity growth.
本文的目的是了解工业化房屋建筑(IHB)是否以及如何在项目和行业层面上支持房屋建筑的生产力发展。这种观点认为,建筑业的碎片化是生产率增长乏力的一个解释,而IHB可能是克服横向和纵向碎片化的一种综合方法。设计/方法/方法单因素生产率指标是根据IHB公司报告的数据计算的,并与官方生产和发表的研究数据进行比较。该调查涵盖了2013-2020年IHB公司建造的多层木材房屋。通过描述性统计,将数据样本与用于控制垂直和水平碎片化的方法进行对比,形成三个理论命题,从而寻求泛化。根据研究结果,在八年的时间里,木材的IHB在公司层面、项目层面平均比传统的住宅建筑更有生产力,无论是绝对的还是增长的。在公司层面,与一般建筑相比,IHB的劳动生产率平均高出10%,处于一般建筑和一般制造业之间。在项目层面上,IHB的平均成本生产率增长了19%,而采用的预制程度约为45%。原创性/价值实证证据量化了迄今为止IHB的感知优势。通过对IHB公司的实际成本和项目数据的分析,本文量化了先前的研究,即IHB不仅仅是关于预制的。观察到的与采用的预制程度相关的正生产率增长表明,非现场生产不是达到高生产率和生产率增长的充分手段。相反,将传统房屋建筑的操作逻辑与IHB平台开发和使用的逻辑相结合的能力可能是观察到的积极生产力增长的一个解释。
