When construction accidents occur, besides the direct impact on the victims, there may be collateral effects on the remaining/uninjured workers. In the context of the aftermath of accidents on construction sites, this research investigates the extent to which the uninjured workers’ productivity is affected; and uncovers the more effective measures to be instituted on workers after witnessing construction accidents so as to prevent further loss of their productivity. A questionnaire survey was conducted on randomly selected construction professionals who had been supervising workers when and after accidents took place on construction sites in Singapore. The data collected were analyzed using the SPSS software. The first finding is that workers’ productivity and wellbeing fall significantly after witnessing construction accidents. They have lower morale, are distressed by the accident and stressed by having to take on additional work or accelerate their work after construction resumes on site. This research found that while a worker’s wellbeing deteriorates significantly in the aftermath of a construction accident, there are upsides to construction accidents too. Workers are observed to adopt better work attitude and have higher sense of safety after construction accidents. Significant positive correlation is found between workers’ wellbeing and their productivity. The second finding is that the workers turn to fellow workers and supervisors for support post accidents. Relieving them from duties are also effective measures to alleviate the psychological effects of the accidents. The study found that to minimize the negative effects of construction accidents, contractors should improve site safety swiftly, offer employee assistance program, relieve workers from regular duties temporarily and refrain from overloading them after work is allowed to resume. It is recommended that supervisors avail themselves to the workers, for example, through mass psychological debriefing or one-to-one counselling.
当建筑意外发生时,除了直接影响受害人外,还可能对其余/未受伤的工人产生附带影响。在建筑工地事故发生后的背景下,本研究调查了未受伤工人的生产力受到影响的程度;揭示了在目睹建筑事故后对工人采取更有效的措施,以防止他们进一步丧失生产力。对随机选择的建筑专业人员进行了问卷调查,这些专业人员在新加坡建筑工地发生事故时和事故发生后一直在监督工人。收集的数据采用SPSS软件进行分析。第一个发现是,目睹建筑事故后,工人的生产力和幸福感显著下降。他们士气低落,对事故感到痛心,而且在现场恢复施工后,必须承担额外的工作或加快工作进度,这给他们带来了压力。这项研究发现,虽然建筑事故后工人的健康状况会显著恶化,但建筑事故也有好处。施工事故发生后,工人的工作态度和安全意识都有所提高。员工的幸福感与生产力之间存在显著的正相关关系。第二个发现是工人在事故发生后会向同事和主管寻求支持。解除他们的职务也是减轻事故心理影响的有效措施。研究发现,为了最大限度地减少建筑事故的负面影响,承包商应该迅速改善现场安全,提供员工援助计划,暂时解除工人的正常工作,并在允许恢复工作后避免超负荷工作。建议主管帮助工人,例如,通过大规模的心理汇报或一对一的咨询。

A Study on a Conceptual Data Model for Developing a Building Fire Information Management System 建筑消防信息管理系统概念数据模型研究
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-104

Recently, as large-scale indoor fires have increased, fire-response systems that enable systematic and effective responses have become more important. Despite the need for the quick and intuitive gathering of relevant information for effective fire response, current information transmission systems are based on paper documents and the opinions of the people nearby. These actions can delay the response time and often cause inappropriate judgments. For an effective fire response in a building, it is important to quickly and intuitively collect and provide relevant information such as location data, available fire equipment, and risk factors in the event of a fire. Building Information Modeling (BIM) can be used in various ways from 3D visualization to spatial data management. Despite these advantages, utilizing data stored in BIM remains a challenge for emergency responders who respond directly at fire sites. This study aims to propose information requirements and conceptual data structure for the development of BIM based building fire information management system for fire response. This can store management history data and build a database so that the required information can be delivered quickly in case of a fire. Based on this paper, the proposed building data structure is expected to design a data model for the construction of the fire related information system database in the field of building disaster management. In future research, a system prototype will be developed with this conceptual model and its effectiveness will be verified by applying it in actual practice. © 2019 The Authors.

最近,随着大规模室内火灾的增加,能够系统有效应对的火灾响应系统变得更加重要。为了有效应对火灾,需要快速、直观地收集相关信息,但目前的信息传递系统是基于纸质文件和附近居民的意见。这些操作可能会延迟响应时间,并经常导致不适当的判断。为了对建筑物进行有效的火灾响应,快速、直观地收集和提供火灾发生时的位置数据、可用消防设备和风险因素等相关信息非常重要。建筑信息模型(BIM)可以用于从三维可视化到空间数据管理的各种方式。尽管有这些优势,但对于直接在火灾现场响应的应急响应人员来说,利用存储在BIM中的数据仍然是一个挑战。本研究旨在为基于BIM的建筑火灾信息管理系统的开发提出信息需求和概念数据结构。这样可以存储管理历史数据并建立数据库,以便在发生火灾时快速传递所需信息。基于本文提出的建筑数据结构,期望为建筑灾害管理领域的火灾相关信息系统数据库建设设计一个数据模型。在未来的研究中,将利用该概念模型开发系统原型,并通过实际应用验证其有效性。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

The Delunay Triangulation in the Design of Architectural Gridshells 建筑格壳设计中的Delunay三角剖分
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-020
A. Stefańska, E. Gawell, W. Rokicki
The design of original gridshell forms has become an increasingly complex process, which aims to search for unique spatial systems which are also effective engineering solutions – both architecturally as well as structurally. The search for synergistic solutions which combine the aesthetics of the form with structural logic is supported by modern bionic tendencies. They allow the reproduction of the organic shapes not only by means of proportions, but also by mimicking the biological developmental processes and by understanding the logic of the structural forms occurring in nature. The analogies between architectural design and morphogenesis of biological forms have increased the interest in bionic structures as a whole. The improvement of digital tools based on algorithmic codes has enabled architects to implement their bold designs based on the logic of Nature’s technologies. One of the most interesting bionic methods of discretization of structural surfaces is Delaunay triangulation, a dual graph of the Voronoi Diagram, which describes the divisions of the plane and space found in nature. Examples can be found in the patterns of a dragonfly wing, giraffe’s mottled skin or a turtle’s shell. The Delaunay divisions are more and more often used in the design of architectural forms based on gridshells. Solutions for such systems are obtained through generative modeling, and the algorithm responsible for the surface discretization is incorporated into 3D modeling programs. A big advantage of using digital generators in the search for optimal architectural and structural solutions is the ability to model multiple-variants and to the easily modify them (the models result from iterations of the entered numerical data). The paper will present the trends in the development of spatial bionic gridshells based on Delaunay triangulation, as well as the results from own research on selected gridshells. The undertaken analyses compare material efficiency on two analyzed cases. © 2019 The Authors. Published by Budapest University of Technology and Economics & Diamond Congress Ltd.

原始网格壳形式的设计已经成为一个越来越复杂的过程,其目的是寻找独特的空间系统,这也是有效的工程解决方案-无论是建筑还是结构。寻求将形式美学与结构逻辑相结合的协同解决方案得到了现代仿生趋势的支持。它们不仅可以通过比例,还可以通过模仿生物发育过程和理解自然界中发生的结构形式的逻辑来复制有机形状。建筑设计和生物形态的形态发生之间的相似性增加了人们对仿生结构整体的兴趣。基于算法代码的数字工具的改进使建筑师能够基于自然技术的逻辑实现他们大胆的设计。结构表面离散化的最有趣的仿生方法之一是Delaunay三角剖分,这是Voronoi图的对偶图,描述了在自然界中发现的平面和空间的划分。蜻蜓的翅膀、长颈鹿的斑驳皮肤或海龟的壳上都有这种图案。Delaunay划分越来越多地被用于基于网格壳的建筑形式设计中。通过生成式建模得到系统的解,并将负责曲面离散化的算法纳入三维建模程序。在寻找最优的建筑和结构解决方案时,使用数字生成器的一大优点是能够对多个变量进行建模,并且可以轻松地修改它们(模型来自输入的数值数据的迭代)。本文将介绍基于Delaunay三角剖分的空间仿生网格壳的发展趋势,以及自己对选定网格壳的研究结果。所进行的分析比较了两个分析案例的材料效率。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

Clients and Construction Health And Safety (H&S) 客户与建筑健康与安全(H&S)
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-090
J. Smallwood
Contractor H&S is influenced directly and indirectly by clients. Furthermore, traditionally, worldwide, better practice client organisations have maintained rigorous contractor H&S management programmes and contributed to contractor H&S. Given the above, a self-administered questionnaire survey was conducted among developer members of the South African Property Owners Association’s (SAPOA) to determine construction H&S perceptions and practices. Findings include: clients view the traditional project parameters of time, quality, and cost as more important than public H&S and project H&S; client organisations can be deemed to have influenced and contributed to contractors’ H&S relative to a range of interventions / requirements; clients appoint agents to fulfil their function in terms of the Construction Regulations; a range of design, procurement, and construction aspects impact on H&S; a range of benefits accrue from client contributions to contractor H&S; clients contend that they have influenced construction H&S, and that they could influence construction H&S more, and a range of design, procurement and construction aspects / interventions can contribute to an improvement in construction H&S. Conclusions include that clients do influence construction H&S and that multi-stakeholder benefits accrue there from, and that clients can further contribute to construction H&S. Furthermore, the client related requirements of the Construction Regulations are underscored by the findings. Recommendations include that property and other built environment tertiary education related programmes should address construction H&S, and SAPOA and other professional associations should evolve construction H&S practice notes.

Analytic Hierarchy Process-Based Model for Estimating Probability of Human Error in Design Stage 基于层次分析法的设计阶段人为错误概率估计模型
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-028

The building information modeling (BIM) technique is used widely in construction. In general, BIM can prevent interference between different types of construction activities in advance, thereby reducing the cost of reconstruction. While it is clear that a decrease in the number of requests for information in the construction stage would have obvious benefits, there is a need to determine the effects of the investment from the planning stage. Therefore, in this study, a procedure for quantifying the design errors that occur at the design stage is proposed considering the probability of the human errors concept. To achieve this, factors for evaluating human errors can arise during the drawing stage. Based on these factors, an analytic-hierarchy-process-based human error probability estimation model is suggested. Based on the factors affecting the error in the design stage, we construct a hierarchy and calculate the relative importance based on the probability and assess the effectiveness of each risk control option. It is expected that if the model presented in this study is linked with the loss cost data for each factor, a loss estimation model at the design stage can be developed. © 2019 The Authors.

建筑信息模型(BIM)技术在建筑施工中得到了广泛的应用。一般来说,BIM可以提前防止不同类型的施工活动之间的干扰,从而降低重建成本。虽然在建设阶段减少索取资料的次数显然会有明显的好处,但有必要从规划阶段就确定投资的效果。因此,在本研究中,考虑到人为错误概念的概率,提出了一种量化在设计阶段发生的设计错误的程序。为了实现这一点,在绘图阶段可能会出现评估人为错误的因素。基于这些因素,提出了一种基于层次分析法的人为错误概率估计模型。根据设计阶段影响误差的因素,构建层次结构,并基于概率计算各风险控制方案的相对重要性,评估各风险控制方案的有效性。如果将本研究提出的模型与各因素的损失成本数据联系起来,可以建立设计阶段的损失估计模型。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

Identification of the Interlayer Bond Between Repair Overlay and Concrete Using Nondestructive Testing, an Artificial Neural Network and Principal Component Analysis 利用无损检测、人工神经网络和主成分分析识别修补铺层与混凝土间的粘结

In construction practice, concrete elements are exposed to adverse environmental influences, and therefore sooner or later require repair. This repair is usually performed by removing the damaged concrete and replacing it with repair overlay. The quality of this repair is evaluated using the destructive pull-off method. In this method, the pull-off adhesion value between the repair overlay and repaired element is measured (fb). Unfortunately, the disadvantage of this method is local damage of the element at every measuring point. It is therefore reasonable to present a reliable nondestructive method of identifying the interlayer pull-off adhesion value. The article presents the results of experimental research, which indicate that such identification is possible using complementary nondestructive methods and an artificial neural network with principal component analysis. © 2019 The Authors.

在施工实践中,混凝土构件受到不利环境的影响,因此迟早需要修复。这种修复通常是通过移除损坏的混凝土并用修复覆盖层替换它来完成的。采用破坏性拉脱法对修复质量进行了评价。在该方法中,测量修复覆盖层与修复元件之间的拉脱附着力值(fb)。遗憾的是,这种方法的缺点是元件在每个测点都有局部损伤。因此,提出一种可靠的、无损的识别层间拉脱附着力值的方法是合理的。本文介绍了实验研究的结果,表明利用互补无损方法和主成分分析的人工神经网络进行识别是可能的。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

Micro BIM Adoption: a Multi-Variable Analysis of Adoption within the UK Architecture Sector 微型BIM采用:英国建筑行业采用的多变量分析
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-120

To date a comprehensive analysis of interactions among BIM adoption factors, stages of the BIM adoption process, and time (e.g. time intervals of a national BIM initiative) is still lacking. This research aims to profile BIM adoption by mapping such interactions. The analysis is performed for the UK Architecture sector, which was represented with a sample of 177 organisations. To achieve the profiling of BIM adoption in the UK architecture sector, the study uses the outcomes from two types of inferential analysis: an ordinal logistic regression test to identify the 11 top factors influencing the BIM adoption process; and correlation analysis among the 11 top factors at different stages of the BIM adoption process (i.e. awareness, intention, and decision) and across three time intervals (i.e. pre-2011 as the time interval preceding the announcement of the UK BIM mandate, 2011-2016 as the time interval for the implementation of the UK national BIM strategy, and post-2016 as the time interval within which the mandate entered into effect). Capturing the interactions involved in the profiling of micro BIM adoption and assimilating the outcomes in a single model unravel a further understanding of the BIM adoption process.

This research aims to profile BIM adoption by mapping such interactions. The analysis is performed for the UK Architecture sector, which was represented with a sample of 177 organisations. To achieve the profiling of BIM adoption in the UK architecture sector, the study uses the outcomes from two types of inferential analysis: an ordinal logistic regression test to identify the 11 top factors influencing the BIM adoption process; and correlation analysis among the 11 top factors at different stages of the BIM adoption process (i.e. awareness, intention, and decision) and across three time intervals (i.e. pre-2011 as the time interval preceding the announcement of the UK BIM mandate, 2011-2016 as the time interval for the implementation of the UK national BIM strategy, and post-2016 as the time interval within which the mandate entered into effect).

Creative Construction and Simplicity of Form 创造性的结构和简单的形式
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-016
Nina Juzwa, Jakub Świerzawski
An Architect designing a form has to take many factors into account. Some are mainly pragmatic and rational in nature. They correspond with the needs and restrictions determined by the user, site or function to name a few. Other factors are subjective to the designer, his/her talent and creativity. One of many tendencies in contemporary architecture is designing buildings that look surprising and innovative. Their complex geometries are usually showing the prestige and the use of modern techniques and technologies. In architecture the relationship between pragmatism, creativity, prestige and astonishment can be seen in buildings which are simple and solid blocks. The feeling of surprise is hidden in the internal structure. The outer form is designed in a pragmatic way while the interior form is different and stunning to the observer. This structure may serve a functional purpose, but the way it is composed into the whole is unexpected. It is this creative construction that underlines the importance and prestige of the object. The relationship between these two structures drives the innovative character of the design. The skill of intuitively explaining a concept becomes essential in the early stage of creating a project, when an idea becomes explicit. A sketch depicting the design concept leading to the materialization of a building shows the architect’s talent. The article examines case studies of objects built in recent years in Poland and in the world, in which such a relationship can be seen. The aim is to show the designers’ motivation, the way of designing and realizing such buildings. This approach allows to outline, how creativity influences the design. © 2019 The Authors.

设计表单的架构师必须考虑许多因素。有些主要是务实和理性的性质。它们与用户、站点或功能确定的需求和限制相对应,仅举几例。其他因素对设计师、他/她的才能和创造力来说都是主观的。当代建筑的许多趋势之一是设计看起来令人惊讶和创新的建筑。它们复杂的几何形状通常显示了现代技术和技术的声望和使用。在建筑中,实用主义、创造力、声望和惊奇之间的关系可以在简单而坚固的建筑中看到。惊喜的感觉隐藏在内部结构中。外部形式以实用的方式设计,而内部形式则是不同的,令人惊叹的观察者。这种结构可能是出于功能性目的,但它被组合成整体的方式是出乎意料的。正是这种创造性的结构强调了该对象的重要性和声望。这两种结构之间的关系推动了设计的创新性。在创建项目的早期阶段,当一个想法变得明确时,直觉地解释一个概念的技能变得至关重要。一幅草图描绘了导致建筑具体化的设计概念,显示了建筑师的才能。本文考察了近年来在波兰和世界上建造的物体的案例研究,其中可以看到这种关系。目的是展示设计者的动机,设计和实现这种建筑的方式。这种方法可以勾勒出创意如何影响设计。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

Design Criteria-Based Probabilistic Estimation Method for Aged Apartment Remodeling Projects in Korea 基于设计准则的韩国老年公寓改造项目概率估计方法
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-040

As apartment get older, it is required to extend the life of the buildings through remodeling and reconstruction. In this situation, members of the apartment choose one of two options. The most important thing in this choice is economical feasibility, which is greatly influenced by the construction cost. There are many cases of reconstruction projects, and accurate construction cost can be calculated. However, remodeling projects are very rare and it is difficult to calculate accurate construction cost. In addition, the remodeling is not only difficult for the members to communicate the design criteria to contractors, but also takes time to reflect them in the estimation, which also affects the decision making. Therefore, this study proposes an estimation method that can integrate the design criteria with in cost. To do this, this study analyzes design criteria based on the previous remodeling cases and classifies them to derive Design Criteria that are required by the members. And it also proposes a range of construction cost by introducing range estimation process to measure the effect of construction cost on each design criterion. In conclusion, this study has been developed an easy-to-use estimation program by combining Excel and Sketchup software. If remodeling cases accumulate in the future, the accuracy and usability of the program are expected to increase. © 2019 The Authors.

随着公寓的老化,需要通过改造和重建来延长建筑物的寿命。在这种情况下,公寓的成员有两种选择。在这种选择中最重要的是经济可行性,而经济可行性受建设成本的影响很大。改造工程的案例很多,可以准确的计算出施工成本。然而,改造工程非常罕见,难以准确计算施工成本。此外,改造不仅成员难以与承包商沟通设计标准,而且需要时间来反映在评估中,这也影响了决策。因此,本研究提出一种将设计准则与成本相结合的估算方法。为此,本研究基于以往的改造案例分析设计标准,并对其进行分类,得出成员所需的设计标准。并通过引入极差估算方法,提出了工程造价的范围,以衡量工程造价对各设计指标的影响。综上所述,本研究结合Excel和Sketchup软件开发了一个易于使用的估算程序。如果在未来重塑案例的积累,该程序的准确性和可用性有望增加。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。

Critical Traits for Effective Leadership Style in the South African Construction Industry 南非建筑行业有效领导风格的关键特征
Pub Date : 1900-01-01 DOI: 10.3311/ccc2019-037

Leadership is associated with certain traits or set behaviours that characterised the leader and which to some extent is essential for influencing others for maximum cooperation and productivity. In some cases, actions may speak better than words. People follow a leader not only because of what he/she says, but what he/she does or is made of. In other words certain qualities are responsible for effective leadership. However, researchers are still oblivious of which trait would always guarantee leadership success. Hence, the search for better leadership traits has continued to this day. Leaders may find themselves in demanding circumstances characterised with complexity, pressure, and uncertainties such as construction and its industry. In such situation, certain leadership traits may be critical more than others for a leader to make headway, as well as influence his/her subordinates towards salvaging the situation to a great extent. The main objective of this paper is to investigate the critical traits for effective leadership among construction professionals in the South African construction industry. The primary research data were collected through a structure questionnaire while the secondary data were collected from a detailed literature review. The survey was conducted in the Gauteng Province of South Africa. Respondents were construction professionals especially project managers. Respondents were selected using heterogeneity and convenience sampling techniques. Data from the questionnaire were analyzed using Statistical Package for the Social Sciences (SPSS) version 23.0 software. Values were represented with descriptive statistics (mean) and standard deviation and were ranked according in descending order. Findings from the study revealed that ability to communicate well is of the optimum importance for effective leadership. Other findings include organised, integrity, self-discipline, experience, courage, visioning, empathy, honesty, problem solving ability, passion, creative, self-confidence, flexible/open to change, ability to inspire/motivate, composure, decisiveness, action oriented, risk taking, foresight, teachable and charisma. The study contributes to the body of knowledge on the effects of effective leadership for optimum performance in the South African construction industry. © 2019 The Authors.

领导力与领导者的某些特征或行为有关,这些特征或行为在某种程度上对于影响他人以实现最大限度的合作和生产力至关重要。在某些情况下,行动胜于言语。人们追随一个领导者不仅是因为他/她说了什么,还因为他/她做了什么或由什么组成的。换句话说,某些品质负责有效的领导。然而,研究人员仍然没有意识到哪种特质总是能保证领导的成功。因此,寻找更好的领导特质一直持续到今天。领导者可能会发现自己处于复杂、压力和不确定性的苛刻环境中,比如建筑及其行业。在这种情况下,某些领导特质可能比其他特质对领导者取得进展更为关键,并在很大程度上影响他/她的下属来挽救局面。本文的主要目的是调查在南非建筑行业的建筑专业人员有效领导的关键特征。主要研究数据是通过结构问卷收集的,而次要数据是通过详细的文献综述收集的。这项调查在南非豪登省进行。受访者是建筑专业人士,尤其是项目经理。受访者的选择采用异质性和方便抽样技术。使用SPSS 23.0版社会科学统计软件包(Statistical Package for the Social Sciences)软件对问卷数据进行分析。数值用描述性统计量(平均值)和标准差表示,并按降序排列。研究结果表明,良好的沟通能力对于有效的领导是最重要的。其他特质包括:有条理、正直、自律、经验、勇气、远见、同理心、诚实、解决问题的能力、激情、创造力、自信、灵活/乐于改变、启发/激励能力、沉着、果断、行动导向、敢于冒险、远见、善于教育和魅力。该研究有助于知识的主体对有效的领导效果的最佳表现在南非建筑行业。©2019作者。由布达佩斯科技经济大学和钻石大会有限公司出版。由2019创意建设大会科学委员会负责同行评审。
