Disruptive method for managing BIM design and construction using Kanban 利用看板管理 BIM 设计和施工的颠覆性方法
Carlos Francisco Lucena Gonzalez, Antonio Manuel Reyes Rodriguez, Francisco Villena Manzanares
Companies in the construction sector need effective information management. In particular, the transmission of information within a company is key to improving its management and competitiveness. Currently, many companies in the construction sector are making a great effort to implement the building information modelling (BIM) methodology. Such implementation requires collaborative work through the Cloud between the different agents in the construction process of any project. In fact, information management in BIM projects is related to the creation, storage, transfer and efficient application of information within a three-dimensional (3D) virtual model of the project. The size of the project also determines the optimal management approach. The main problems resulting from poor information management may be a lack of coordination between actors, loss of information or misinterpretation of information. This work has two stated objectives. The first objective is to carry out a literature review of the applications of BIM technology and the importance of managing knowledge according to International Organisation for Standardisation (ISO)- 19650. The second objective is to propose a disruptive method based on the Kanban tool to properly manage BIM information in the design and construction phases. This paper has practical implications for the improvement of BIM application for project managers.
建筑行业的公司需要有效的信息管理。尤其是公司内部的信息传递是提高公司管理水平和竞争力的关键。目前,许多建筑行业的公司都在大力推行建筑信息模型(BIM)方法。这种方法的实施需要任何项目施工过程中不同代理之间通过云进行协同工作。事实上,BIM 项目中的信息管理与项目三维(3D)虚拟模型中信息的创建、存储、传输和有效应用有关。项目的规模也决定了最佳的管理方法。信息管理不善导致的主要问题可能是参与者之间缺乏协调、信息丢失或信息误读。这项工作有两个既定目标。第一个目标是对 BIM 技术的应用以及根据国际标准化组织 (ISO)19650 管理知识的重要性进行文献综述。第二个目标是提出一种基于看板工具的颠覆性方法,以便在设计和施工阶段妥善管理 BIM 信息。本文对改进项目经理的 BIM 应用具有实际意义。

Life-cycle cost estimation of a building structure: An example of partition walls 建筑结构的生命周期成本估算:以隔墙为例
V. Biolek, T. Hanák
The growing pressure to optimise construction investment costs from the life-cycle perspective inevitably leads to efforts to seek new solutions that will facilitate informed decision-making in the early stages of the construction project. Awareness of the importance of considering future operation and demolition costs emphasises the shortcomings related to the possibility of making accurate predictions/estimations of such costs, which will become apparent in the future. To address this research gap, an innovative approach of life-cycle cost modelling on the level of individual structures of the building is presented. The model provides users with information on the costs of available technical solutions resulting from the requirements of the investor at a specific stage of the construction project. In this way, it helps investors optimise their building projects and to find the most economical solutions. Specifically, this model is assembled for the purpose of selecting a suitable partition wall and, therefore, it takes into consideration specific characteristics relating to this particular type of structure. The results indicate diversity in partition wall structural design variants at the early stage of the project. Since the ability to influence future costs decreases as the project progresses, the model allows capturing LCC perspective even if only a construction study is available without more detailed technical and economic information. The presented model aims to contribute to the higher performance of construction projects in the planning phase from the perspective of LCC and investors’/owners’ point of view.
从生命周期的角度优化建筑投资成本的压力越来越大,这不可避免地促使人们努力寻求新的解决方案,以便在建筑项目的早期阶段做出明智的决策。对考虑未来运营和拆除成本重要性的认识,强调了与对此类成本进行准确预测/估算的可能性有关的不足之处,这些不足之处在未来将变得非常明显。针对这一研究空白,提出了一种创新方法,即在建筑物单个结构层面上建立生命周期成本模型。该模型为用户提供了根据投资方在建筑项目特定阶段的要求所产生的可用技术解决方案的成本信息。通过这种方式,它可以帮助投资者优化建筑项目,找到最经济的解决方案。具体来说,该模型是为选择合适的隔墙而组装的,因此考虑到了与这种特殊类型结构有关的具体特征。结果表明,在项目早期阶段,隔墙结构设计变体具有多样性。由于影响未来成本的能力会随着项目的进展而降低,因此即使只有施工研究而没有更详细的技术和经济信息,该模型也能捕捉到 LCC 的视角。本模型旨在从 LCC 和投资者/业主的角度出发,提高规划阶段建筑项目的绩效。

The factors that affect constructability in Iraq 影响伊拉克施工能力的因素
O. A. Ahmed, A. Mahjoob
Applying the constructability concept in the construction industry has proven many benefits in different projects; however, this concept still lacks usage in Iraq. Therefore, it is important to encourage usage of the constructability concept in the construction industry in Iraq. The main purpose of this study is to investigate the factors that affect constructability in Iraq and then classify them according to their importance. A total of 37 factors were collected from an intensive literature review, and they were classified under the sub and main categories. A survey was undertaken in two sessions with open questionnaire and close questionnaire. The results were analysed and the mean, standard deviation and Cronbach’s Alpha were obtained. Also, the developed weight was calculated for each alternative factor. The goal of this paper is to define the main factors that have an effect on Iraqi’s constructability project in order to avoid issues in future Iraqi projects. The outcome showed that 34 factors had a major effect on increasing the constructability percentage in construction projects in Iraq. The top-ranking factors were structural frame types, high-strength concrete usage, adjacent infrastructures and adjacent site.

Comparative assessment of deterministic methodologies for estimating excavation productivity 估算挖掘生产力的确定性方法的比较评估
Antonios Panas, John-Paris Pantouvakis, Maria Kalogiannaki
Abstract This paper investigates the prediction capability of deterministic methodologies in estimating construction productivity for earthmoving operations. Published literature includes several estimation methodologies stemming from (a) equipment manufacturers’ manuals, (b) editions from German contractors’ associations or individual researchers and (c) textbook editions. The purpose of this research is to assess the yielded productivity estimation results under the prism of 14 estimation methodologies. It is – to the authors’ best knowledge – the first research attempt for the comparative evaluation of such a diverse set of estimation methodologies, with the aim of quantifying their effects on the operations analysis in earthmoving works. A uniform mathematical modelling approach is used to formulate the relevant estimation equations and, subsequently, a real-case scenario of an earthmoving project in Greece is used as a benchmark against which the robustness of each methodology is assessed. A sensitivity analysis on main productivity factors concludes the research. The preliminary results indicate that equipment manufacturers’ methods are more optimistic and present higher sensitivity to specific productivity factors (e.g. swing angle, excavation depth), whereas the German-oriented approaches are more conservative with less variability due to differing productivity factors.
摘要本文研究了确定性方法在估算土方工程施工生产率方面的预测能力。已发表的文献包括几种估算方法,这些方法来自(a)设备制造商的手册,(b)德国承包商协会或个人研究人员的版本,以及(c)教科书版本。本研究的目的是在14种评估方法的棱镜下评估产出的生产力评估结果。据作者所知,这是第一次对如此多样化的评估方法进行比较评估的研究尝试,目的是量化它们对土方工程操作分析的影响。使用统一的数学建模方法来制定相关的估计方程,随后,将希腊一个土方工程的实际情况作为基准,对每种方法的稳健性进行评估。对主要生产要素进行敏感性分析。初步结果表明,设备制造商的方法更为乐观,对特定的生产力因素(如摆动角度、挖掘深度)具有更高的敏感性,而德国导向的方法更为保守,由于不同的生产力因素,变异性较小。

James Olaonipekun Toyin, Modupe Cecilia Mewomo
Abstract The construction industry has been experiencing high waves of revolutionised innovative technologies globally. These resulted from the highly innovative demands of the 4th industrial revolution (IR), which does not exclude the construction industry. These technologies do not rely on traditional design and build principles, and they require sophisticated skills and competencies. Currently, the construction industry is still struggling to find professionals with innovative competencies and the skills needed to manage the building lifecycle process. These have been a major concern in developing countries’ construction industry sector. Employers in the construction industry are now looking for construction management graduates (CMG) who are academically qualified and also possess considerable construction-related innovative skills and competencies in related technological software or tools. This study investigates the expected core skills and competence required by CMG. The methodology entails a well-structured systematic literature review, wherein 13 expected core competencies and 27 expected core skills were identified. Based on these, primary data were elicited through an online Google Forms survey distributed to professionals in the Nigerian construction industry. A total of 330 valid responses were obtained. Relative Important Index (RII) and principal component analysis (PCA) were carried out and presented. The result reveals the industry’s expectations and provides guidance to CMG seeking employment in the construction industry. Understanding the industry expectations and possessing the required core competencies will enable the CMG to remain relevant in the dynamic built environments. This study contributes to building information modelling (BIM) knowledge and the current innovative competencies and skills required in the built environment.

Protecting the intellectual property of built environment designs using blockchain technology 使用区块链技术保护建筑环境设计的知识产权
Mohammad Darabseh, João Poças Martins
Abstract Digital design and modelling for construction assets was an important step towards improving the construction process overall by improving its efficiency and productivity, reducing the time needed for design editing and rework. However, digital forms of designs are prone to cyber threats and misuse by unauthorised authors. This is a common problem in different industries wherein digital asset management is inefficient due to its centralisation and depends on humans following a certain procedure. Blockchain is an emerging technology capable of transferring digitally produced information into a transferable digital value by storing the information or an identifying signature for the information on a blockchain ledger. Information on the blockchain ledger is immutable and stored in a decentralised system, making it a permanent record. This article investigates the possibility of protecting the intellectual property of built environment designs using blockchain technology. The article presents a solution for generating a double-fingerprint identity for the Industry Foundation Classes (IFC), a common format for built environment design exchange, followed by deployment of a smart contract on the Ethereum public blockchain to store the design fingerprint along with design meta-data, such as information about the the owner and version, as a non-fungible token, a unique asset format stored on a blockchain ledger.
摘要:建筑资产的数字化设计和建模是通过提高其效率和生产力,减少设计编辑和返工所需的时间来改善整体施工过程的重要一步。然而,数字形式的设计容易受到网络威胁,并被未经授权的作者滥用。这是不同行业的一个常见问题,其中数字资产管理由于其集中化而效率低下,并且依赖于人类遵循一定的程序。区块链是一种新兴技术,能够通过在区块链分类账上存储信息或识别签名,将数字生产的信息转换为可转移的数字价值。区块链分类账上的信息是不可变的,存储在一个分散的系统中,使其成为永久记录。本文探讨了使用区块链技术保护建筑环境设计知识产权的可能性。本文提出了一种为工业基础类(IFC)生成双指纹身份的解决方案,这是一种用于建筑环境设计交换的通用格式,随后在以太坊公共区块链上部署智能合约,以存储设计指纹以及设计元数据,例如有关所有者和版本的信息,作为不可替代的令牌,存储在区块链分类账上的独特资产格式。

Using the ordinal priority approach for selecting the contractor in construction projects 运用顺序优先法选择建筑工程承包商
Sajjad Ali Mahmood Alkaabi, Ahmed Mohammed Raoof Mahjoob
Abstract Effective decision-making process is the basis for successfully solving any engineering problem. Many decisions taken in the construction projects differ in their nature due to the complex nature of the construction projects. One of the most crucial decisions that might result in numerous issues over the course of a construction project is the selection of the contractor. This study aims to use the ordinal priority approach (OPA) for the contractor selection process in the construction industry. The proposed model involves two computer programs; the first of these will be used to evaluate the decision-makers/experts in the construction projects, while the second will be used to formulate the OPA mathematical model. The experts’ interview was used to identify the criteria of evaluation process of the decision-makers/experts, while Delphi survey with principal component analysis (PCA) was conducted to identify the required selection criteria of the construction projects contractors. The results illustrate that there are 20 criteria for selecting the construction contractor, and 7 criteria for evaluating the decision-makers/experts in the construction projects. Finally, the proposed model has been applied in a real construction project, and showed good results.
有效的决策过程是成功解决任何工程问题的基础。由于建设项目的复杂性,在建设项目中做出的许多决策在性质上是不同的。在建设项目的过程中,可能导致许多问题的最关键的决定之一是承包商的选择。本研究的目的是使用顺序优先法(OPA)的承包商选择过程中,在建筑行业。所提出的模型涉及两个计算机程序;其中第一份将用于评估建筑项目的决策者/专家,而第二份将用于制定OPA的数学模型。采用专家访谈法确定决策者/专家评价过程的标准,采用德尔菲调查法结合主成分分析法确定建设项目承包商的选择标准。结果表明,选择建设承包商的标准有20个,评价建设项目决策者/专家的标准有7个。最后,将该模型应用于实际工程,取得了良好的效果。

Green supply chain drivers and their implementation on LEED-certified projects in India 绿色供应链驱动因素及其在印度leed认证项目中的实施
Pawan Koul, Ranjit Roy Ghatak, Kunal Sinha
Abstract This study aims to identify the most critical green supply chain drivers and to explore the most prevalent drivers in the real estate industry in India. Through literature review, we identified 13 green drivers in the real estate sector in India. A structured questionnaire was administered to 280 potential participants, out of whom 150 responded by filling out the questionnaire. The respondents were working in reputed real estate companies comprising owners, contractors, consultants, architects, and project management companies in Delhi National capital region (NCR). The relative relevance index was used to rank the various green drivers in the real estate industry in India. Multiple regression analysis was used to establish the degree of linear connection between the variables. T-tests examine the differences between 13 decision factors and dependent variables. The cost–benefit of green supply chain drivers in a LEED-certified real estate project in India established the efficacy of green supply chain drivers in the real estate industry in India. The study’s findings indicate that senior management, developers, and the government are the most crucial drivers for implementing the green supply chain in the real estate sector. The study’s findings further confirm that green building approaches, i.e., green procurement, green transportation, building information modelling (BIM), building energy modelling (BEM), and prefabrication procedures, are underutilised in the real estate sector in India.
本研究旨在确定最关键的绿色供应链驱动因素,并探讨印度房地产行业最普遍的驱动因素。通过文献综述,我们确定了印度房地产行业的13个绿色驱动因素。对280名潜在参与者进行了结构化问卷调查,其中150人填写了问卷。受访者在德里国家首都地区(NCR)的知名房地产公司工作,包括业主、承包商、顾问、建筑师和项目管理公司。相对相关指数被用来对印度房地产行业的各种绿色驱动因素进行排名。采用多元回归分析确定变量之间的线性联系程度。t检验检验13个决策因素和因变量之间的差异。绿色供应链驱动在印度leed认证房地产项目中的成本效益验证了绿色供应链驱动在印度房地产行业的有效性。研究结果表明,高层管理人员、开发商和政府是房地产行业实施绿色供应链的最关键驱动因素。研究结果进一步证实,绿色建筑方法,即绿色采购、绿色运输、建筑信息模型(BIM)、建筑能源模型(BEM)和预制程序,在印度的房地产行业未得到充分利用。

A competency framework for strategic planning managers in multi-business holding organisations 多业务控股组织中战略规划经理的能力框架
Mahmoud Ershadi, Mohammad Rahimi Moghaddam, Mohammad Ebrahim Raei Ezabadi
Abstract Nowadays, the business environment is dynamic and constantly changing, which intensifies competition among companies. The complexity of competition in multi-business holding companies is higher than in other organisations due to the complexities of different industries and their uncertainties in terms of investment policies and corporate strategies. Such companies need a strategic plan to align business requirements with their various functions. In this regard, strategic planning managers (SPMs) have a significant role in analysing possible business scenarios and putting optimal plans in place to guarantee their implementation in a specific timeline. This study aims to identify and discuss the necessary competencies and capabilities of this cohort of managers. In the present article, a qualitative approach was adopted, and the findings are based on observations in a case study multi-discipline holding organisation. The viewpoints of the key managers were obtained, and a competency framework was developed. The results indicate that the professional competencies of SPMs can be explained in terms of the two aspects of (1) strategy formulation and (2) strategy implementation. A framework is presented in this paper that summarises the viewpoints of managers in the case study organisation on the requisite competencies of SPMs. Although prior studies explain the general competencies of managers from a universal perspective, this study steps beyond the borders of such models and extends the literature on the professional competencies of a specific and most influential cohort of business managers in holding organisations through an in-depth case study.
如今,商业环境是动态的、不断变化的,这加剧了企业之间的竞争。由于不同行业的复杂性及其在投资政策和公司战略方面的不确定性,多业务控股公司的竞争复杂性高于其他组织。这样的公司需要一个战略计划,使业务需求与其各种功能保持一致。在这方面,战略规划经理(SPMs)在分析可能的业务场景和制定最佳计划以确保其在特定时间内实现方面发挥着重要作用。本研究旨在识别和讨论这群管理者的必要胜任力和能力。在本文中,采用了定性方法,研究结果基于对多学科控股组织案例研究的观察。获得了关键管理者的观点,并开发了一个胜任力框架。研究结果表明,企业战略管理者的专业能力可以从战略制定和战略实施两个方面来解释。本文提出了一个框架,总结了案例研究组织中管理人员对spm必要能力的观点。虽然先前的研究从普遍的角度解释了管理者的一般能力,但本研究超越了这些模型的边界,并通过深入的案例研究扩展了关于控股组织中特定且最有影响力的业务经理群体的专业能力的文献。

Employee perspective on site accidents and corporate reputation in developing countries 发展中国家员工对工地事故和企业声誉的看法
Michael Adesi, De-Graft Owusu-Manu, Frank Boateng, Moses Ahiabu
Abstract Brief introduction to the Problem Construction accident studies often overlook the internal perspective of employees on site accidents’ impact on corporate reputation. Purpose This study investigates the effects of construction site accidents on corporate reputation from an internal viewpoint of stakeholders, focusing on employees. It also determines the extent of the association between site accidents and corporate reputation in middle-income economies. Design/methodology/approach A quantitative approach was used, with 150 survey questionnaires administered to employees in construction firms using purposive sampling. Descriptive and inferential statistical tools, including the Pearson correlation and factor analysis, were used to analyse the results. Findings Site accidents have 17 identified effects on corporate reputation, negatively impacting leadership, financial management, ethics, shareholder value, and sustainability. Originality This study highlights the significant impact of construction site accidents on corporate reputation from an internal perspective of employees and identifies the need for more research on this issue. It has the potential to influence construction health and safety research focus, which has previously not addressed the issue of corporate reputation from an internal perspective.
施工事故的研究往往忽视了员工内部的角度来研究现场事故对企业声誉的影响。目的本研究以员工为研究对象,从利益相关者的角度探讨建筑工地事故对企业声誉的影响。它还决定了中等收入经济体中工地事故与企业声誉之间的关联程度。设计/方法/方法采用定量方法,对建筑公司的员工进行了150份调查问卷,采用有目的抽样。使用描述性和推断性统计工具,包括Pearson相关和因子分析来分析结果。现场事故对企业声誉有17个确定的影响,对领导力、财务管理、道德、股东价值和可持续性产生负面影响。本研究从员工的内部角度强调了建筑工地事故对企业声誉的重大影响,并指出需要对此问题进行更多的研究。它有可能影响建筑健康和安全的研究重点,以前没有从内部角度解决企业声誉问题。
