Cofferdams made of teel sheet piles are commonly utilized as support structures for excavation of sea-crossing bridge foundations. As cofferdams are often subject to tide variation, it is imperative to consider potential effects of tide on stability and serviceability of sheet piles, particularly, ultralong steel sheet piles (USSPs). In this study, a real USSP cofferdam constructed using new construction technology in Nanxi River was reported. The design of key parts of USSP cofferdam in the presence of tidal action was first introduced followed by the description of entire construction technology and associated monitoring results. Subsequently, a three-dimensional finite-element model corresponding to all construction steps was established to back-analyze measured deflection of USSPs. Finally, a series of parametric studies was carried out to investigate effects of tide level, soil parameters, support stiffness and construction sequence on lateral deflection of USSPs. Monitoring results indicate that the maximum deflection during construction occurred near the riverbed. In addition, measured stress of USSPs showed that stability of USSP cofferdam strengthened as construction stages proceeded. Moreover, the numerical back-analysis demonstrated that the USSP cofferdam fulfilled the safety requirements for construction under tidal action. The maximum deflection of USSPs subject to high tide was only 13.57 mm at a depth of -4 m. Sensitivity analyses results showed that the design of USSP cofferdam system must be further improved for construction in cohesionless soils. Furthermore, the 5th strut level before concreting played an indispensable role in controlling lateral deflection of USSPs. It was also observed that pumping out water before concreting base slab could greatly simplify and benefit construction program. On the other hand, the simplification in construction procedures could induce seepage inside the cofferdam, which additionally increased the deflection of USSPs by 10 mm on average.

Employability is a critical issue in construction education. Employability is more than students obtaining employment upon graduation. The concept is far more ranging, and should encompass enabling students to acquire the knowledge, personal and professional skills and encouraging attitudes that will support their future development and employment. This paper describes two case studies relating to how the true concept of employability can be incorporated into the construction higher education curriculum. Case study 1 was a collaborative venture with contributions from a higher education provider, employers, students and a professional body (Association of Building Engineers). It outlines the whole process from course inception through to graduation and feedback. Thus it presents a valid model for other higher education providers of construction courses to adapt or adopt. Case study 2 outlines how the opportunity of a degree programme revalidation process was utilized to introduce modules which would enhance students' employability on graduation.

Safety education, which aims to cultivate an understanding of safety, to help acquire safety skills, and to improve attitude toward safety, is an important safety measure that doesn't entail restrictions to be carried out efficiently. Furthermore, safety education is perceived to be the most preferred measure in reducing the occurrence of accident. The current practice of safety education In construction sites, however, is all formal and has no substance. Safety education became a mere boring time to workers since the material is not related to them, and does not reflect the individual personalities, which cannot induce voluntary participation of workers. Thus, it is vital to develop various safety education models suitable for individual personalities of construction workers. This study aims to provide the basic data necessary to establish safety education models according to individual personalities of construction workers. On this, the study seeks to present a model for safety education complying with individual personality of construction workers by a survey using questionnaires and statistical analyses to workers on the construction sites.

Purpose: Ten years after basic safety and health education in the construction industry has been implemented, no more maintenance education has been provided, and those who have completed basic safety and health education are exempt from new employee education. As soon as possible, we will seek strategic measures to prevent unstable behavior and prevent safety accidents by legislating conservative education and new recruitment education. Method: In this study, basic safety and health education, which is construction safety education, and human error, which is unstable behavior of new employees, and structural relationship between violation behavior were conducted through survey. Result: The survey analyzed that basic safety and health education in the construction industry and new recruitment education had a significant impact on the human factors of the disaster, Human Error, and the reduction of violations, and confirmed that continuous safety education could increase safety awareness. Conclusion: The insolvency of safety education shall be prevented by the revision of the Act on the remuneration of basic safety and health education and the education of new employees.

Currently, there is a lack of studies on the directionality of architectural engineering education. This study has analyzed the opening and operation of courses relating to building construction in Korea universities. It was researched that the most common building construction courses opened in universities were 'building construction' and 'materials.' Courses are also being opened in universities by reflecting social demands. Upon analysis of the operation of the educational process of building construction, it was displayed that projects and examinations were conducted as the methods of assessment in courses at many universities. Additionally, there were universities that included quizzes and discussions in their methods of assessment. This study is expected to be used as data for studying an innovative means of educating architecture.

In the past, the domestic construction industry mainly comprised quantitative investment through the supply of labor force, however, there have recently been opinions that there is a need for qualitative investment in the workers in order to obtain competitiveness in construction markets. Accordingly, there are much re-education courses for workers in the construction industry, but there is much negative awareness as to the efficiency of the current re-education course due to many problems. This study aimed to examine the problems o f currently executed re-education courses and proposed an improvement plan for the qualitative enhancement of domestic construction re-education. Thus, a multiple regression analysis was conducted to deduce two core problems an improvement plan. The improvement plan for the problems comprised the NCS/CDP-based integrative education program through an AHP. The contribution of this paper will result in the execution of a more effective construction industry re-education program, and the result of such program to achieve qualitative growth in the workers in the construction industry

The prevention of safety accidents can be achieved through Harvey's 3E's: Engineering, Enforcement, and Education. On construction sites, however, enforcement and engineering did not prove to be valid ways of reducing the number of safety accidents, as enforcement and engineering have failed to overcome and/or supplement the realistic limits regarding the relatively lower education levels of construction workers and the communication issues with foreign workers. On the other hand, safety education can enable the advancement of safety management by enhancing the educational contents and their methods of delivery. To improve the efficiency of safety education via educational contents, this research conducted a qualitative and quantitative analysis on the validity of the newly educational contents by overviewing possible accident types in different work phases. Of the accident types identified by the qualitative analysis, neither highly important nor insignificant accident types were found, yet all the suggested types are found to be required. In addition, this study did not find any significant differences in the occurrence probability of safety accidents related to the level of importance of each type of accident. The qualitative analysis in this research verified that the suggested accident types can be valid, educational material that can take into account future safety accidents.

The architecture, engineering and construction (AEC) industry is beginning to utilize Building Information Modeling (BIM), benefiting from the resulting improved visualization and productivity, better coordination of construction drawings, building documents that contain embedded links to virtual information, faster delivery, and lower costs. However, construction firms often face challenges when reorganizing their company structure to take full advantage of these benefits. This paper proposes an organizational structure that will enable engineering-construction firms to successfully adopt and implement BIM for major construction projects. A case study research method is utilized based on in-depth interviews with four BIM directors and vice presidents charged with BIM adoption, implementation and education. Organizational transformation challenges and recommendations are discussed in detail for those considering implementing BIM in the engineering-construction industry. Topics such as organizational changes in the firm, costs and benefits of BIM implementation, strategies of BIM implementation (execution) plan, BIM education, risks and opportunities associated with BIM, BIM software, contract methods, human resource management and new hires, and the future implementation and direction of BIM are discussed in detail.
