The rapid development of advanced technologies and methods of Industry 4.0 represents in recent decades the basis for radical changes in traditional project management in all industrial sectors. It is a digital transformation, with a trend in digitalization and automation processes, and which in turn has a significant impact on the construction industry. Thus, the traditional construction project management has outgrown its basic elements and is focused on the challenges of comprehensive handling of mass data about the planned or built building. Therefore, managing construction projects today focuses on the use of Building Information Modeling (BIM), which is a digital platform where all information is collected in one place and accessible to all stakeholders throughout the construction project cycle. In this context, the basic education and continuous development of professionals through lifelong learning is so important. Through this learning, professionals acquire knowledge and competencies for working in this area, which is especially important for successful management of construction projects. Therefore, this chapter provides a more detailed overview of formal and informal learning at a higher education institution that focuses on advanced construction project management.
近几十年来,工业4.0先进技术和方法的快速发展为所有工业部门传统项目管理的根本变革奠定了基础。这是一种数字化转型,具有数字化和自动化过程的趋势,这反过来又对建筑行业产生了重大影响。因此,传统的建筑项目管理已经超越了它的基本要素,而是专注于对规划或建造的建筑的大量数据进行综合处理的挑战。因此,今天管理建筑项目的重点是使用建筑信息模型(BIM),这是一个数字平台,所有信息都收集在一个地方,在整个建筑项目周期中所有利益相关者都可以访问。在此背景下,通过终身学习的基础教育和专业人才的持续发展就显得尤为重要。通过这种学习,专业人员获得了在这一领域工作的知识和能力,这对于成功管理建筑项目尤为重要。因此,本章提供了一个更详细的概述在高等教育机构正式和非正式的学习,重点是先进的建设项目管理。

Today it is hard to imagine new things, inventions and any accomplishments without projects standing behind them. Projects of any kind are a crucial part of our world; they have become the way of thinking and inevitable foundation for successful businesses. In order to produce a desirable impact on the community, project goals must be achieved – in other words, projects must be successful. Nevertheless, it often seems that we live in a world of unsuccessful project endeavors. Many authors agree that problems occurring in implementation phase could have been foreseen in conceptualization and planning. Therefore, planning has been recognized as a critical phase for projects to succeed. High-quality plans enable easier procurement, contracting, monitoring and control – leading to a better project management and overall project success. One of the most popular project management tools for project planning, especially when it comes to budgets, is a well-known S-curve. S-curve is simple, clean, report and user-friendly. All the above is stressed on the special manner when it comes to the largest and most complex projects – infrastructure projects. In Croatia, as well as other EU members, infrastructure projects are mostly EU co-financed, and often contracted via FIDIC terms of contract, which makes planning phases even more important. This research was conducted in order to contribute to the improvement of baselines and projection of financial realization. Theoretical baseline and empirical S-curves on portfolio of FIDIC Red and Yellow Book contracted projects in water sector were analyzed and compared, with the aim of proposing adjusted prognostic S-curves of financial absorption and therefore contribute to more efficient planning and implementation of projects.
今天,如果没有项目的支持,很难想象新的事物、发明和任何成就。任何一种计划都是我们这个世界的重要组成部分;它们已经成为企业成功的思维方式和必然的基础。为了对社区产生理想的影响,必须实现项目目标——换句话说,项目必须成功。然而,我们似乎经常生活在一个项目努力不成功的世界里。许多作者认为,在实施阶段出现的问题可以在概念化和规划中预见到。因此,计划已被认为是项目成功的关键阶段。高质量的计划使采购、承包、监督和控制变得更加容易,从而实现更好的项目管理和整体项目的成功。最流行的项目规划管理工具之一,特别是当涉及到预算时,是一个众所周知的s曲线。s曲线简洁、干净、报表、用户友好。所有这些都强调在涉及最大和最复杂的项目-基础设施项目时的特殊方式。在克罗地亚和其他欧盟成员国,基础设施项目大多是由欧盟共同资助的,并且通常通过FIDIC合同条款签订合同,这使得规划阶段更加重要。进行这项研究是为了有助于改善财务实现的基线和预测。分析比较FIDIC水务部门红皮书和黄皮书合同项目组合的理论基线和经验s曲线,提出调整后的资金吸收预测s曲线,从而有助于更有效地规划和实施项目。

An Integrated Solution for increased Circularity in Buidings: A Method 增加建筑循环度的综合解决方案:一种方法

The transformation from a linear to a circular economy remains very slow worldwide. The abundance of materials measured in billions of tonnes is transferred annually within the economy, with minimal materials being cycled back. The construction sector uses approximately half of the materials extracted while generating a third or more of all waste. The current circular potential in the construction industry is yet to be exploited. This paper addresses the issue of materials embedded in buildings and the possibility of their reversible capacities. This paper aims to develop a systemic methodological framework on how to create, collect, process and present data that could facilitate the improvement of a more efficient recovery process of embedded building materials, especially their reuse and high-quality recycling during the renovation and demolition processes. The proposed framework defines a methodological approach for developing an interactive digital solution, a digital map, to increase circularity in a built environment by integrating spatial data and building information models (BIMs). To this end, a four-step methodological approach is introduced: (1) development of BIMs for the existing building stock; (2) allocation of material inventory data to BIMs; (3) calculation of circular economy indicators; and (4) digital solution integration into 3D Geographic Information Systems (GIS). This map may facilitate maximising the circular potential of buildings, support data transparency and broaden accessibility to a broad spectrum of market participants. It could be imbued with tools such as a digital building logbook with which it could share data.
在世界范围内,从线性经济向循环经济的转变仍然非常缓慢。每年在经济中转移的大量材料以数十亿吨计,而回收的材料最少。建筑部门使用了大约一半的材料,同时产生了三分之一或更多的废物。目前建筑行业的循环潜力还有待开发。本文讨论了建筑中嵌入材料的问题及其可逆能力的可能性。本文旨在开发一个关于如何创建、收集、处理和呈现数据的系统方法框架,这些数据可以促进嵌入式建筑材料更有效的回收过程的改进,特别是在翻新和拆除过程中对其进行再利用和高质量回收。拟议的框架定义了一种开发交互式数字解决方案的方法,即数字地图,通过整合空间数据和建筑信息模型(bim)来增加建筑环境的循环性。为此,介绍了一个四步骤的方法:(1)为现有建筑存量开发bim;(2)将物料库存数据分配给bim;(3)循环经济指标的计算;(4)数字解决方案与三维地理信息系统(GIS)的集成。该地图可以促进最大化建筑的循环潜力,支持数据透明度,并扩大对广泛市场参与者的可及性。它可以被注入诸如数字建筑日志之类的工具,与之共享数据。

What are the Special Usances in Construction? 施工中有什么特殊用途?
Pub Date : 2023-07-06 DOI: 10.5592/ce/senet.2022.10
Antun Bilić
Half a year ago, the Croatian Chamber of Economy and the Croatian Employer’s Association issued the Special Usances in Construction, which regulate the legal relationship between the client (employer) and the contractor. This continues a long tradition of codifying the commercial usages into usances (uzance). It was, however, never sufficiently explored whether the commercial usages can at all be codified. Even if the answer is affirmative, it was not sufficiently explored whether the usances indeed reflect the existing commercial usages. The aim of this research paper is to bridge such gap by analysing the nature of usances and, in particular, the Special Usances in Construction. Several methods are used. First, the textual analysis of the usances. Second, the analysis of jurisprudence. Third, historical method, which explores the origin of usances in former Yugoslavia. The analysis leads to the conclusion that neither earlier usances nor the Special Usances in Construction reflect the existing commercial usages. Instead, they imitate statutory provisions, e.g. by containing the date of the entry into force and even (purportedly) mandatory provisions. Consequently, the Special Usances in Construction have to be qualified as a quasi-legislative instrument. Considering that the legislative power cannot be delegated, unless the parties agree on their application, the Special Usances in Construction cannot be used as a source of law.
半年前,克罗地亚经济商会和克罗地亚雇主协会发布了《建筑特别惯例》,其中规定了客户(雇主)和承包商之间的法律关系。这延续了将商业用途编纂成用法(uzance)的悠久传统。然而,对于商业用途是否可以编纂,却从来没有进行过充分的探讨。即使答案是肯定的,也没有充分探讨这些用法是否确实反映了现有的商业用法。本研究论文的目的是通过分析用途的性质,特别是建筑中的特殊用途,来弥合这种差距。使用了几种方法。首先,对用法的文本分析。第二,法理学分析。第三,历史方法,探索前南斯拉夫使用的起源。分析得出结论,早期用法和特殊用法都不能反映现有的商业用法。相反,它们模仿法定规定,例如载有生效日期,甚至(据称)强制性规定。因此,《施工特别须知》必须被限定为一种准立法文书。考虑到立法权不能下放,除非当事人同意其适用,否则不能将建筑特殊用途作为法律渊源。

The aim of this paper is to structure information on environmental characteristics that influence housing prices so that it can be effectively used in the valuation process through digital visualization. A suitable data platform for real estate valuation entities should contain information about the spatial data of the urban grid in a structured form that is stored digitally and accessible to all. OpenStreetMap can be considered as such a platform. It is a relatively user-friendly open tool that can be used for spatial and market analysis. This activity is very necessary in the valuation process as it is very time consuming and requires extensive data collection. This paper examines the environmental spatial characteristics in the urban grid to see whether or not they have an impact on the price of housing. These influences are examined using a non-parametric test that allows two groups or conditions to be examined. The Mann-Whitney U test is a test for ordinal data that is similar to a two-sample t-test. Nonparametric tests are used when a certain distribution of the data cannot be assumed. The paper concludes by presenting a systematic approach to incorporating information on the urban grid characteristics under investigation into open data platforms to streamline the property valuation process. The results can be suitably generalized to other commodities and markets
本文的目的是构建影响房价的环境特征信息,以便通过数字可视化有效地用于估值过程。适合房地产估价实体的数据平台应以结构化形式包含有关城市网格空间数据的信息,以数字方式存储并供所有人访问。OpenStreetMap可以被视为这样一个平台。这是一个相对用户友好的开放工具,可用于空间和市场分析。这项活动在估价过程中是非常必要的,因为它非常耗时,需要收集大量数据。本文考察了城市网格中的环境空间特征,看看它们是否对住房价格产生影响。这些影响使用非参数检验,允许检查两组或条件。Mann-Whitney U检验是对有序数据的检验,类似于双样本t检验。当不能假设数据的某个分布时,使用非参数检验。本文最后提出了一种系统的方法,将所调查的城市网格特征信息纳入开放数据平台,以简化房地产估值过程。这些结果可以适当地推广到其他商品和市场

Multi-Objective Optimization Approach To Develop Resilient Baseline Schedules 弹性基线调度的多目标优化方法
Pub Date : 2023-07-06 DOI: 10.5592/ce/senet.2022.1
Martina Milat, S. Knezic, Jelena Sedlar
Time and cost overruns are a major problem in the construction industry, and this is particularly noticeable in complex projects where the dynamic environment causes many undesirable disruptions during the execution of a project. Therefore, it is important to develop effective strategies for overcoming the negative impact of uncertainty, so the initial planning calculations can be accepted with higher confidence levels. The main purpose of this study is to propose a multi-objective optimization approach to manage prevailing uncertainty in the process of construction planning by producing resilient solutions. This framework deploys a comprehensive optimization problem and a metaheuristic solving procedure to devise baseline schedules that are resilient to prevailing uncertainty in complex construction projects. Such an approach leads to a higher probability of respecting both due date and budget restrictions in a construction project. Simulation results show that by inserting suitable floats in a baseline schedule, the overall capacity to absorb uncertain prolongations is improved. Since the stability of an initial schedule is enhanced, a resilient baseline solution leads to less frequent schedule updates during the execution phase and it facilitates subcontracting practices as well as resource procurement. Implementation of modern optimization methods in construction planning practices enables practical solving of complex scheduling problems that are important for general project management.
时间和成本超支是建筑行业的一个主要问题,这在复杂的项目中尤其明显,因为在项目执行过程中,动态环境会导致许多不受欢迎的中断。因此,制定有效的策略来克服不确定性的负面影响是很重要的,这样初始的规划计算才能被更高的置信度所接受。本研究的主要目的是提出一种多目标优化方法,通过产生弹性解决方案来管理施工规划过程中普遍存在的不确定性。该框架部署了一个全面的优化问题和一个元启发式解决程序,以设计基线时间表,以适应复杂建设项目中普遍存在的不确定性。这样的方法更有可能在建设项目中尊重到期日和预算限制。仿真结果表明,通过在基线调度中插入合适的浮动,可以提高系统对不确定延时的吸收能力。由于初始进度表的稳定性得到了增强,弹性基线解决方案可以在执行阶段减少进度表更新的频率,并促进分包实践和资源采购。在施工规划实践中实施现代优化方法,可以实际解决复杂的调度问题,这对一般项目管理很重要。

A Novel Approach of Structural FE Modelling Using 4D Architectural Design Sketches 一种利用四维建筑设计草图进行结构有限元建模的新方法
Pub Date : 2023-07-06 DOI: 10.5592/ce/senet.2022.23
Dalel Daleyev, S. Rasoulzadeh, Iva Kovacic
This paper describes a novel methodology for a quick structural finite element (FE) modelling of free-form and high-rise structures sketched within a developed 4D semantic, mixed reality sketching application, targeted for early stages of architectural design, followed by a shape inference pipeline. The novel approach presented in this paper intends to estimate structural viability for the architectural concept in the early preliminary draft. A fast collaborative export of geometrical data from the sketching app to the generative algorithm for the assembling of structural topology will be used to define analytical FE model. With pre-defined data, such as material information and the type of load-bearing system, a simple linear-elastic FE calculation will be conducted in order to analyse the structural parts in ultimate (ULS) and serviceability limit states (SLS) and point out the problematic places. Once the decision regarding the architectural design of the sketched structure is made, the compiled FE model will be afterwards transferred to a commercial FE software in order to undergo further, more detailed structural analysis. The advantage of the described modelling method is a) time saving as it generates a model directly upon architectural design, and b) by generation of the plausible FE model in the very early stages of planning and post-editing it during the process.
本文描述了一种新的方法,用于在开发的4D语义混合现实素描应用程序中对自由形式和高层结构进行快速结构有限元(FE)建模,目标是建筑设计的早期阶段,然后是形状推理管道。本文提出的新方法旨在评估建筑概念在早期初步草案中的结构可行性。将几何数据从素描应用程序快速协同导出到结构拓扑组装的生成算法,用于定义分析有限元模型。根据材料信息和承载系统类型等预先定义的数据,进行简单的线弹性有限元计算,以分析结构件的极限状态(ULS)和使用极限状态(SLS),并指出问题所在。一旦对结构草图的建筑设计做出决定,编译好的有限元模型将随后转移到商业有限元软件中,以便进行进一步,更详细的结构分析。所描述的建模方法的优点是a)节省时间,因为它直接在建筑设计上生成模型,b)在规划的早期阶段生成合理的有限元模型,并在过程中对其进行后期编辑。

Infrastructure is one of the vital technical elements of our modern lives, with its wide scope of broad environmental, social and political impacts. Nevertheless, infrastructure projects are often prone to underachievement in budget, time, quality or goals. In order to find out the state of infrastructure project management in Croatia, as well as neighboring countries, the authors conducted research with the aim of detecting the most critical areas of infrastructure project management in the context of challenge and opportunity identification and connection. Systematic research steps were taken, based on the adoption of the framework analysis approach. 17 project management experts in the field of water, electricity, railway, road, port, gas, waste landfill, hospital, building and soft infrastructure participated in in-depth interviews. Their views on challenges, risks, opportunities and regional experience-sharing are discussed, the most significant concerning strategic planning, public procurement, project management competencies and public administration. On the basis of their answers and expert group engagement, a comprehensive framework for the transformation of infrastructure project challenges into opportunities is made. Finally, an applicable conclusion and recommendations for future research are given. The results of this research may be of service to project management experts, scholars and interested members of the public in the creation of epistemology on infrastructure projects and the maximization of their benefits.

BIM (Building Information Modeling) has been one of the rapidly developing fields of digital techniques supporting the realization of construction projects in recent years. Further development, and especially the use of these techniques, depends to a large extent on the qualifications of young construction engineers who start their professional careers in this field. The article attempts to synthetically list and compare subjects, specializations or fields related to teaching about the BIM methodology in Polish universities curricula. The aim of the study is to present the key factors and differences in the approach to education in this field and on this basis an attempt to formulate conclusions regarding the optimal way of conducting the didactic process in the field of BIM education. The subject of the research were BIM education offers at Polish universities at various levels of education. The places where education occur at Polish universities were identified and the time of implementing BIM technology teaching was compared. The levels, paths, graduate profile, educational programs, the presence of practical elements, the achieved results as well as the types, forms and modes of conducting classes at individual universities were analyzed. The analysis was conducted on the basis of information available on the Internet about the faculties and programs of education of individual universities, supplemented with additional information obtained in e-mail correspondence and conducted by telephone interviews. As a result of the analyzes, the key guidelines for conducting education at the university level were proposed.

Actively adaptable and responsive structures in architecture have recently gained momentum thanks to the emergence of affordable programable controllers, various sensors, new deformable materials, increase in computing power, algorithmic complexity of design and driver software, and other technological improvements. A distinctive type of structures in art and architecture that emerged from this setting is pneubotics – a type of structures formed by combining robotics with pneumatic structures. In this work a simple analysis and basic classification of contemporary pneubotic structures in art and architecture is given to inform the design possibilities that opened with the emergence of this structural polytype. Based on the analysis of the characteristics they exhibit, various possible uses of pneubotics in architectural design are proposed. These range from soft adaptable seismic insulation, adaptable frame structures, self-erecting structures, protective, control and otherwise technical devices, building envelope, etc. Given the early development of soft adaptable and responsive pneumatic structures these proposals should be taken rather as an inspiration for further research and development.
由于可负担得起的可编程控制器、各种传感器、新的可变形材料、计算能力的提高、设计和驱动软件的算法复杂性以及其他技术的改进,建筑中的主动适应性和响应结构最近获得了动力。在这种背景下,艺术和建筑中出现了一种独特的结构类型,即气动结构——一种将机器人技术与气动结构结合起来形成的结构。在这项工作中,对艺术和建筑中的当代气动结构进行了简单的分析和基本分类,以告知随着这种结构多型的出现而开启的设计可能性。在分析它们所表现出的特点的基础上,提出了气动技术在建筑设计中的各种可能用途。这些范围包括软适应性地震绝缘,适应性框架结构,自立结构,保护,控制和其他技术设备,建筑围护结构等。鉴于软适应性和响应式气动结构的早期发展,这些建议应该被视为进一步研究和发展的灵感。
