Investigating the challenges related to combining BIM and Last Planner System on construction sites

Conrad BOTON, Yaya PITTI, Daniel FORGUES, Ivanka IORDANOVA

《工程管理前沿（英文）》 2021年第8卷第2期页码 172-182 doi: 10.1007/s42524-019-0086-4

摘要： The construction industry is facing a gradual but important transformation toward more productivity and collaboration. In this framework, two major approaches are often cited in the literature as having the potential to improve the practices in the industry: Building Information Modeling (BIM) and Lean Construction. Several scientific studies have demonstrated the synergy of these two approaches and very recent research has reported positive results from the use of software applications as support for their implementation on construction sites. However, the stakes of such integration have been very little studied. This article presents the results of a research project conducted within a general contractor firm that decided to implement BIM and Last Planner System (LPS) on its construction sites. The research uses a four-stage action research approach, including the characterization of the research issue, the establishment of an action plan, its implementation and its evaluation. Compared to recent related studies, the research is less enthusiastic. While it highlights the need for new tools to improve production planning and control, it also points to a strong resistance to change by practitioners at the site. They emphasize the necessity for adequate pre-service training and the need for new resources that can work full-time on the ongoing training of site teams. In addition, some limitations of the tool lead workers to believe that it can quickly become a factor that slows down their daily work rather than improving it. Based on the advice of professionals, the paper formulates some recommendations to the industry, the researchers and the software developers.

Aerodynamic challenges in span length of suspension bridges

XIANG Haifan, GE Yaojun

《结构与土木工程前沿（英文）》 2007年第1卷第2期页码 153-162 doi: 10.1007/s11709-007-0016-0

摘要： The potential requirement of extreme bridge spans is firstly discussed according to horizontal clearances for navigation and economical construction of deep-water foundation. To ensure the technological feasibility of suspension bridges with longer spans, the static estimation of feasible span length is then made based on current material strength and weight of cables and deck. After the performances of the countermeasures for raising the aerodynamic stability are reviewed, a trial design of a 5 000 m suspension bridge, which is estimated as a reasonable limitation of span length, is finally conducted to respond to the tomorrow s challenge in span length of suspension bridges with the particular aspects, including dynamic stiffness, aerodynamic flutter and aerostatic stability.

《结构与土木工程前沿（英文）》 2007年第1卷第1期页码 12-33 doi: 10.1007/s11709-007-0002-6

摘要： The current situations and growing prospects of China s hydro-power development and high dam construction are reviewed, giving emphasis to key issues for safety evaluation of large dams and hydro-power plants, especially those associated with application of state-of-the-art computational mechanics. These include but are not limited to: stress and stability analysis of dam foundations under external loads; earthquake behavior of dam-foundation-reservoir systems, mechanical properties of mass concrete for dams, high velocity flow and energy dissipation for high dams, scientific and technical problems of hydro-power plants and underground structures, and newly developed types of dam-Roll Com pacted Concrete (RCC) dams and Concrete Face Rock-fill (CFR) dams. Some examples demonstrating successful utilizations of computational mechanics in high dam engineering are given, including seismic nonlinear analysis for arch dam foundations, nonlinear fracture analysis of arch dams under reservoir loads, and failure analysis of arch dam-foundations. To make more use of the computational mechanics in high dam engineering, it is pointed out that much research including different computational methods, numerical models and solution schemes, and verifications through experimental tests and filed measurements is necessary in the future.

Systematic literature review on smart contracts in the construction industry: Potentials, benefits, andchallenges

《工程管理前沿（英文）》 2022年第9卷第2期页码 196-213 doi: 10.1007/s42524-022-0188-2

摘要： The development of digital transformation in the construction industry has led to the increasing adoption of smart contracts. As programmable applications to automatically write, verify, and enforce transaction conditions, smart contracts can be used in different areas mainly to improve automation level, information security, and built digital environment enhancement. However, the smart contract is commonly mentioned as a blockchain appendage, while its unique connotation and value in the construction industry have not been recognized. Therefore, this study carries out a systematic review based on 81 research articles published from 2014 to 2021 on smart contract applications in construction to explore and highlight their potentials under domain-specific requirements. Results are analyzed according to research type categorization and domain codification. Eight research domains are identified, where the three most highly explored domains are contract and payment, supply chain and logistics, and information management. The integration of smart contracts with other innovative concepts and advanced technologies is analyzed. The applicability, benefits, and challenges of smart contract applications regarding different research domains are discussed.

雷洋,黄承锋,张学进

《中国工程科学》 2019年第21卷第4期页码 124-130 doi: 10.15302/J-SSCAE-2019.04.021

摘要：

伊朗铁路经过百年发展，在伊朗综合运输体系中占据重要地位。为满足伊朗国内经济社会发展需要，发挥国际交通枢纽的区位优势，伊朗制定了为期10 年的铁路发展规划，计划到2025 年，铁路网络既有线路全部实现电气化改造，复线率提升至100%，并且实现铁路里程翻番目标。伊朗铁路提升计划为中资企业进入伊朗工程建设市场提供了利好和机遇，中资企业参与伊朗铁路提升计划也面临“伊核协议”不确定性、营商环境不佳、铁路建设领域大国“角逐”，以及技术标准选择偏好等四方面的挑战。研究建议，中资企业参与伊朗铁路建设市场，不仅需要敏锐捕捉机会，也需要谨慎评估存在的风险；结合国际政治经济形势，综合权衡成本和收益，进行理性决策，在响应“一带一路”倡议过程中，稳健地实施“走出去”战略。

Emerging challenges to structural integrity technology for high-temperature applications

TU Shantung

《机械工程前沿（英文）》 2007年第2卷第4期页码 375-387 doi: 10.1007/s11465-007-0066-y

摘要： Structural integrity technology has been widely used with great success for the design, manufacture and failure prevention of modern constructions such as chemical and petrochemical plants, power generation and energy conversion systems, as well as space and oceanic exploration. The modern needs of structural integrity technology are largely attributed to the increase of service temperature of the structures that results in the efficiency improvement in energy conversion and chemical processing technologies. Besides the needs arising from large-scale high-temperature plants, the high tech developments, such as micro chemo-mechanical systems and high-power electronics, provide new challenges to structural integrity technology. The present paper summarizes the recent technical progresses in large process plants and the aviation industry, micro chemo-mechanical systems, fuel cells, high-temperature electronics, and packaging and coating technologies. The state-of-the-art of structural integrity technology for high temperature applications is reviewed. Suggestions are provided for the improvement of current design and assessment methods.
