Identifying stakeholders’ roles and relevant project documents for 4D-based collaborative decision making

Veronika BOLSHAKOVA, Annie GUERRIERO, Gilles HALIN

《工程管理前沿（英文）》 2020年第7卷第1期页码 104-118 doi: 10.1007/s42524-019-0041-4

摘要： To fully understand and effectively implement 4D building information modelling (BIM) models and methods, we need to develop a precise knowledge of which project digital documents should be used and how they influence the decision-making (DM) process. This article studies the convergence between uses of 4D BIM and digital project documents. We hypothesize that a clear visualization of the construction simulation through a 4D model is a useful source of information and a support for DM at collaborative meetings. Through this research, we continue to progress toward a new 4D-based collective decision device, so these elements will contribute to propose 4D BIM as DM support on architecture engineering construction (AEC) projects. Further, the present research will be complemented by results from questionnaires given at a later research stage. The article presents a brief review of BIM context to consider ways of fostering the implementation of all 4D BIM uses (not only visualization). It then introduces a proposition for 4D BIM uses implementation by the project development phase. It concludes by summarizing stakeholders’ roles and documents relevant to 4D BIM uses.

Semantics for linking data from 4D BIM to digital collaborative support

Calin BOJE, Veronika BOLSHAKOVA, Annie GUERRIERO, Sylvain KUBICKI, Gilles HALIN

《工程管理前沿（英文）》 2022年第9卷第1期页码 104-116 doi: 10.1007/s42524-020-0111-7

摘要： Synchronous collaboration sessions within the context of 4D BIM position construction professionals into a complex socio–technical system. This system includes hardware, software, people, and broader community aspects. This article strictly focuses on the ontology representation of synchronous collaboration sessions with collocated collective decision-making. The model is designed by considering various 4D BIM model uses while a digital multiuser touch table facilitates the collaboration between actors. The outlined ontological model aims to improve interoperability and to move toward a knowledge-driven, smart-built environment paradigm. A knowledge engineering methodology is outlined, by virtue of which the semantics of the presented model are defined and discussed. Concepts from nearby knowledge fields, especially from the Industry Foundation Classes, are reused. Several examples on querying the knowledge base according to the project meeting requirements are outlined to demonstrate the benefits of using the model. Although 4D BIM model data can be imported by using standard formats, capturing data about the social context remains a challenge in the future. This is expected to change the ontology model structure by considering user ergonomics, data modeling requirements, as well as technical implementation constraints.

Amelia Yilin Lee, Jia An, Chee Kai Chu, Yi Zhang

《工程（英文）》 2019年第5卷第6期页码 1159-1170 doi: 10.1016/j.eng.2019.09.007

摘要：

增材制造的快速发展和形状记忆聚合物材料的进步推动了四维（4D）打印技术的进展。随着设计方面的不断改进，逐渐证明有可能实现可逆4D打印或双向4D打印。这项技术将完全消除对人为干预的需要，因为编程完全由外部刺激驱动，这使得4D打印部件可以在多个周期内启动。本研究提出了一种新的可逆4D打印驱动方法，其中弹性体的溶胀和热量用于编程阶段，以及热量用于恢复阶段。本研究的主要重点在于自驱动设计这一步骤。采用这种方式理解曲率可以提供对可逆4D打印结构的高度控制。

4D打印定律 Article

Farhang Momeni, Jun Ni

《工程（英文）》 2020年第6卷第9期页码 1035-1055 doi: 10.1016/j.eng.2020.01.015

摘要：

三维(3D)打印是一种增材制造工艺。相应地，四维(4D)打印是一个涉及多个研究领域的制造工艺。4D打印保留了3D打印的一般属性(如减少材料浪费、消除注射模具、冲压模具和机械加工过程)，并且随着时间的推移能实现产品第四维度的智能行为。3D和4D打印结构的主要区别是4D打印存在一个附加的维度，这个维度可以随着时间的推移进行智能进化。然而，目前还没有用于建模和预测这个附加维度的一般公式。研究表明，需要利用两种类型的时间常数来捕捉4D多材料的正确的时间相关性行为。本文引入了4D多材料结构中主动材料和被动材料的界面错配压力的概念，从而得到了两个时间常数之一。本文的结果从最基本的概念开始，并以控制方程结束，可以作为未来4D打印领域研究的一般设计原则，其中时间相关性行为应该被正确地理解、建模和预测。

双向4D打印——对3D打印形状记忆材料可逆性的回顾

Amelia Yilin Lee, Jia An, Chee Kai Chua

《工程（英文）》 2017年第3卷第5期页码 663-674 doi: 10.1016/J.ENG.2017.05.014

摘要：

增材制造技术的快速发展和形状记忆材料的进步推动了四维（4D）打印的发展。随着目前对形状记忆机制的理解和对增材制造技术的改进设计，4D 打印的可逆性已经被证明是可行的。传统的单向4D 打印需要在编程（或定型）阶段进行人机交互，但是可逆的4D 打印或双向4D 打印将完全消除对人为干预的需求，因为编程阶段被另一种外界刺激所取代。这使得可逆4D 打印部件完全依赖外部刺激。本文综述了影响4D 打印的形状记忆材料的机制，目前在合金和聚合物上的4D 打印研究结果，以及它们各自存在的一些局限性。对形状记忆材料的可逆性和利用三维（3D）打印技术制作的可行性进行了总结和分析。在对可逆4D 打印技术相关内容的介绍中，本文也强调了3D 打印技术的方法、相关驱动的机制以及实现可逆性的策略。最后，提出了可逆4D 打印技术未来的研究方向。

Virtual pre-assembly for large steel structures based on BIM, PLP algorithm, and 3D measurement

Ying ZHOU, Wan WANG, Hanbin LUO, Yan ZHANG

《工程管理前沿（英文）》 2019年第6卷第2期页码 207-220 doi: 10.1007/s42524-019-0016-5

摘要： The current physical pre-assembly method of large steel structures is time consuming and costly and requires large sites. Thus, the pre-assembly of large steel structures in a virtual way, starting from building information modeling (BIM), is an interesting alternative to the physical one. In this study, an innovative method for virtual pre-assembly is proposed on the basis of BIM, plane-line-point algorithm, and 3D measurement. This method determines the optimal analytical least squares of the various built components. The technique verifies the feasibility of the steel structure assembly and the fulfillment of the design geometries, starting from the real data obtained by an accurate metric survey of the fabricated steel elements. The method is applied to a real case, and obtained results largely satisfy the prefixed research objectives. Suggestions to improve the proposed method are also discussed.

Symbiotic performance, shoot biomass and water-use efficiency of three groundnut (

MUHABA, Felix D. DAKORA

《农业科学与工程前沿（英文）》 2020年第7卷第4期页码 455-466 doi: 10.15302/J-FASE-2020354

摘要：

Phosphorus is a key nutrient element involved in energy transfer for cellular metabolism, respiration and photosynthesis and its supply at low levels can affect legume nodulation, N fixation, and C assimilation. A two-year field study was conducted in Ethiopia in 2012 and 2013 to evaluate the effects of P supply on growth, symbiotic N nutrition, grain yield and water-use efficiency of three groundnut genotypes. Supplying P to the genotypes significantly increased their shoot biomass, symbiotic performance, grain yield, and C accumulation. There was, however, no effect on shoot δ C values in either year. Compared to the zero-P control, supplying 40 kg·ha P markedly increased shoot biomass by 77% and 66% in 2012 and 2013, respectively. In both years, groundnut grain yields were much higher at 20 and 30 kg·ha P. Phosphorus supply markedly reduced shoot δ N values and increased the %Ndfa and amount of N-fixed, indicating the direct involvement of P in promoting N fixation in nodulated groundnut. The three genotypes differed significantly in δ N, %Ndfa, N-fixed, grain yield, C concentration, and δ C. The phosphorus × genotype interaction was also significant for shoot DM, N content, N-fixed and soil N uptake.

Understanding barriers to BIM implementation: Their impact across organizational levels in relation toBIM maturity

Sander SIEBELINK, Hans VOORDIJK, Maaike ENDEDIJK, Arjen ADRIAANSE

《工程管理前沿（英文）》 2021年第8卷第2期页码 236-257 doi: 10.1007/s42524-019-0088-2

摘要： This multiple case study of a contracting firm contributes to understanding the barriers that organizations face during the implementation of building information modeling (BIM) by providing insights into the impact of these barriers across different organizational levels (i.e., from top management to project teams) and by relating these barriers to different degrees of BIM maturity. First, we observe the dominance of barriers related to the motivation, competence, and time capacity of people across all levels of an organization. Second, the cluster of barriers at the middle-management level highlights the important role of this level in reducing these barriers. Third, only those cases with a low level of BIM maturity have struggled with lack of top management support, thereby highlighting the importance of such support in achieving BIM maturity growth. High BIM maturity situations are more prone to externally oriented barriers in attempting to further leverage the benefits of BIM. Our study provides insights on where to focus BIM implementation measures and how to enhance organizational BIM maturity.

Generic and SME-specific factors that influence the BIM adoption process: an overview that highlights

Elodie HOCHSCHEID, Gilles HALIN

《工程管理前沿（英文）》 2020年第7卷第1期页码 119-130 doi: 10.1007/s42524-019-0043-2

摘要： Building information modeling/management (BIM) is an emerging technological and procedural shift in the architecture, engineering, construction and operation industry. In this study, we use an extensive state-of-the-art method to clarify the BIM adoption process and the factors that can influence the success or failure of BIM adoption, particularly during the implementation stage, which are not frequently found in the literature. As an innovation, the lexical field allocated to the spread of innovations is assigned to BIM (diffusion, adoption, and implementation). After recalling the definition of relevant terms and then removing the resulting inconsistencies in vocabularies, we investigate various studies to identify factors that influence BIM adoption and then unify all these studies in one coherent and consistent BIM adoption process model. We focus on factors that play a role in the adoption of BIM in small- and medium-sized enterprises (SMEs) because SMEs constitute the majority of companies in the construction sector. This research highlights and intends to fill in some gaps found in the current BIM adoption literature.
