Building foundations for Top-Down construction require a special setting, because the foundations have to be placed way before excavation for the substructure of main building, Usually, the foundation goes into the layer of rock and it is often called rock-pier foundation, Currently, a cage of steel reinforcing bars is inserted to the pre-excavated hole in the rock layer, hanging down from the wide flange steel column above. This paper presents a new method for connecting the prefounded column and the steel cage with a coupler for better connection between the two, The use of a circular Concrete Filled Tube (CFT) as a prefounded column makes it possible to have this type of connection. The details of the connection and application to a Top-Down construction site is also included in this paper.

It has been debating on the performance evaluation of professional construction management (PCM) services since its introduction to Taiwan's construction industry more than a decade ago. Several evaluation systems were proposed by previous researchers. However, there has no comparison study been conducted for the feasibility, effectiveness, and appropriateness of these systems to the performance management (PM) of practical PCM services. This paper is intended for this end to compare the existing PCM performance evaluation systems in Taiwan. A real world design/build (D/B) building project was selected for case study. The result of case study concludes and compares the pro's and con's of the three systems. At the end, it recommends strategies for selecting the most appropriate PCM performance evaluation for PCM services.

There is a limit to preventing various types of safety accidents in advance at construction sites. Even for buildings of the same total floor area, it is expected that the more complex the building shape or the higher the number of floors, the higher the probability of a safety accident. Therefore, it is necessary to analyze the effect of the shape of a building on safety accidents using safety accident data generated during actual construction. The purpose of this study is to analyze the impact of building shape on safety accidents. As a result, the R2 value of shape factor and safety accident was 0.901, and the R2 value of construction difficulty and safety accident was 0.944. In the future, the results of this study will be used as basic data for improving safety management related systems.

Recently, the need to strengthen the Air Environment Conservation Act and secure alternative heat sources during the winter by carbon neutrality policies has been raised. Accordingly, winter construction, which has safety and quality measures, is emerging as an essential factor. It is believed that eco-friendly tropical type electric hot air heaters will be able to solve most of the problems of winter construction at construction sites, especially prevention of suffocation and fire accidents. In addition, as a result of on-site performance verification, it has secured more than the same performance as the existing curing method, and the curing technology can create an eco-friendly and pleasant working environment while considering safety and construction.

Construction market situation has been changed quickly in the 21st century. One is a large variety of information, the other is the development of IT technology among the rest of the change. Accordingly, it is very important that information is managed systematically and made good use of broadly in proportion to the increase of information volume. Therefore, the purpose of this study is to propose a applicable classification system in the construction phase. First of all, the Construction Information Classification proposed by the government is studied to apply the actual work and to build a applicable construction information classification for construction project. A base of the applicable classification system is the Construction Information Classification, SMM and Materials classification(Public Procurement Service). The applicable classification system to control and manage the construction information is consist of the 4 types : Facility classification, Element classification, Work classification, Resource classification (Materials, Equipment, Labor).

Construction industry is an important key industry and many measures to revitalize it as local economy has been stagnant. However, construction industry works combined with governmental policies, global and local economies, populations, construction companies and many other related factors, and it is very hard for those counter-plans to meet every need and goal of the related. In this study, interviews and questionnaires of the professionals of the construction industry in Busan, were carried out, to find the cause of the inactivity of the construction market, the problems of the policies and regulations, and the problems of the construction companies in Busan and the solutions were suggested. The realistic master-plans and the reduction of the cost price for the problems of the redevelopment business having no feasibility, the reasonable relaxation of the restrictions for the problems of the governmental policies, the professional training and education for the lack of the high-quality human resources and the working system changes for the problems of the local construction companies turned out as results. The results of the study will be a chance to understand the different ideas of the professionals, and help with the plans to improve and to revitalize the local construction industry. The results of the study will be a chance to understand the different ideas of the professionals, and help with the plans to improve and to revitalize the local construction industry.

Current trends in the Korean construction industry, including the aging of the workforce, a lack of new Korean construction workers, and an inflow of unskilled foreign labor, have caused a range of problems, including quality deterioration, reduced productivity, insufficient understanding of the function and difficulties in communication, to name a few. Yet while countermeasures to these problems should be based on accurate and diverse fundamental data, including the current status of demand and supply of domestic and foreign construction workers, the perception of construction workers, studies on these questions have, thus far, been scarce. For these reasons, this study was conducted using a questionnaire for managers and workers on construction sites, to secure fundamental data relating to construction workers. The findings of the survey showed that it is urgent to prepare measures to educate, train and foster human resources, considering the aging of the construction workforce and the lack of an inflow of new construction workers.

Identifying the root causes of substandard construction projects is crucial considering the social and economic issues structural failures can cause. To date, the focus has predominantly been on identifying and penalizing the culprits rather than uncovering the fundamental reasons. Therefore, this study aims to identify various factors that contribute to failures in construction project quality management, including aspects of substandard construction projects, and determine the relationship between these factors and substandard construction projects. Through a literature review and case analysis, 61 influential factors were identified. A survey targeting participants including structural designers, architectural designers, construction companies, CM, and researchers was conducted to gauge the consensus on these factors. A regression analysis was performed based on data from 724 survey respondents. Ultimately, based on the 17 key influencing factors identified by the regression analysis, 9 preventive measures against substandard construction projects were proposed. This study is significant as it elucidates the reasons behind construction project quality management failures that lead to substandard construction projects and establishes a framework for developing practical solutions to real-world problems rather than theoretical or abstract ones.

The protection of the environment is one of today's key demanding international activities and interests. All of aspects including industry, economy and society should be changed into environmental friendly industries. The building is not exception in this trend. What is not generally realized is that building, in the lifecycle of construction, use and demolition, account for large construction, not considered with environment impact and conservation in the lifecycle. Expecially, the construction materials and components used in the construction stage has much embodied energy. And much $CO_2$ emit on the production of the construction material and component. The energy use and $CO_2$ emission would continuously diminish the limited natural resources and impact the environment such as ozon layer destruction. In this paper, it studied the estimation of the amount of energy use and $CO_2$ emission in the building construction stage, it would provide the estimation process and applied with the multifamily housing.
