최근 수년 동안에 국내에서는 많은 초고층건물들이 완공되었다. 지금도 다수의 초고층건물들이 시공되고 있으며, 심지어 100층 이상 규모의 초고층건물까지도 기획 중에 있다. 이러한 초고층건물공사의 현장관리 측면에서 중요성이 강조되는 관리항목들 중 하나는 시공 과정 중에 발생하는 자원의 수직이동을 관리하는 것이다. 특히 짓고자 하는 건물의 높이가 높아질수록 작업원들이 각자의 작업층으로 이동하는데 걸리는 시간은 길어지며, 자칫하면 이것이 현장의 작업능률과 생산성을 떨어뜨리는 원인이 될 수 있다. 이에 본 연구에서는 초고층건물공사 수행 시 작업원의 수직이동을 체계적으로 관리하기 위한 한 가지 방안으로서 이산형 시뮬레이션을 사용한 작업원의 수직이동계획 프로세스를 제안하였으며, 계획 프로젝트인 MT 130 타워공사를 대상으로 이것의 적정성을 검토하였다.

The number of high-rise buildings has increased year after year, with there currently being 5 projects in progress to construct buildings higher than 100 stories in Seoul alone. The construction cost for such high-rise buildings is significantly higher than the cost for a conventional low-rise building, while maintenance costs are expected to be two to three times higher. To reduce the maintenance cost of a high-rise building, there is the need for a guide rail to be used for maintenance, which is why there is the need for research on the guide rail system. For this reason, as preliminary research to develop a guide rail, this study aims to derive the factors increasing construction cost by taking the installation of a guide rail into account. This is expected to lay the groundwork for the design and construction of guide rails for high-rise building maintenance.

As residents and building owners demand maintenance that is required to achieve sustainable building performance, efficient building management methods are required. Even though the demand for maintenance systems is increasing, current maintenance work for high-rise buildings mostly uses conventional ropes and gondolas that pose a high risk of accidents and exhibit poor performance and efficiency. Thus, there is an urgent need to develop an automation robot system that can reduce accidents and improve the maintenance efficiency of the conventional high-rise building façade maintenance system. As a preceding work for the development of an automation robot system, this study classified and analyzed the work processes of actual construction sites and proposed basic techniques for the work mechanisms of the robot system by investigating the motions of cleaning workers.

At the economical crisis of Korea in 1997, self-determined price for apartment and the revision increasing the ratio of residential area for mixed-use residential building were introduced to activate the construction industry, which causes construction companies to build super high rise apartment discriminative and high class orientated. This study aims to classify the super high rise building which is planned to build or built recently and to analyze the architectural characteristics. The objects are 288 unit households in 26 apartment complexes higher than twenty five story since 1998. As a result, super high rise building comparing with existing apartments were being varied in plan types of main building and unit household and in construction types. As for the plan, the number of walls having opening to outdoor were increased and it is considered that high rise building can take advantage of a view, lighting and sunshine. The location of living room that used to be in the center of unit in existing apartment was moved freely without rule.

Recently, the development of alternative energy technologies has been actively conducted for energy conservation and CO₂ emission reduction. Especially, photovoltaic energy has been applied practically in construction industry, and research on the building-integrated photovoltaic system (BIPV) that can replace fossil fuel for building operation and maintenance has been performed. However, this vibrant research has been limited to the use phase of buildings, and few studies have been carried out in the construction phase. The construction duration and the scale of the sites have increased along with the high-rise trend of buildings, and it is forecasted that the temporary electricity use and CO₂ emission in the construction phase is increasing. In sight of these developments, this research analyzed applicability of the photovoltaic system for the construction phase that can replace the electricity used on the high-rise construction site.

Recently, high-strength concrete used for shortening the construction time of high-rise building construction, Concrete pumping technology is emerging as the core technology of high-rise buildings. In this paper, we have started to study the use of electromagnetic field as a method to increase the efficiency of the lubricating layer between the inside of the pipe and concrete, which has been established as the most important factor determining the pumping performance. The pumping performance improvement effect of concrete strength was verified and basic research was carried out to utilize it as a method to increase the efficiency of pumping in field application. In the related work, the effect of the electromagnetic field was verified by conducting a mock-up performance evaluation (horizontal 300 m) of the pumping force by the concrete strength.

Modular construction technique is an adaptation of factory-based mass production concept in ordinary manufacturing industries to construction industry and it assumes that panels, units, etc. are fabricated in factories and assembled in construction sites. Given its structural limitations, modular construction technique is primarily used in low-story buildings whose maximum height is usually five stories, but researchers are actively studying possible adaptation of modular construction technique to high-rise building designs these days as in the case of infill-type modular construction design. Infill-type modular construction technique, most frequently used in high-rise building construction projects, completes frame construction first in reinforced concrete structures and fills unit modules in such structures. However, infill-type modular construction technique leads to longer construction schedule accompanying increase in construction cost, cost overrun due to additional of temporary work, and possible damage to units in the wake of facility construction. Accordingly, this study is performed as a basic study for the development of bottom-up infill-type modular construction technique intended to construct structural frames and fill in units sequentially in a bid to address such drawbacks of current infill-type modular construction technique.

The construction industry has become larger and higher in size. The process of high-rise building construction is complicated and has various conditions affecting productivity. Analysing productivity in high-rise buildings is difficult despite the various productivity analysis methods. In this study, data was collected from actual construction site to analyse the productivity of curtain wall operation by means of Work sampling and Method Productivity Delay Model. As a result, this paper suggests advantages and disadvantages deducted from comparing the two productivity analysis methods.

High rising of the buildings offers a number of risk factors than ever before with regard to fire prevention. Especially in the construction site of high-rise buildings, people waste golden-time during the evacuation because temporary fire fighting facilities are not installed and transferred to a large fire because of fire suppression failure. In this study, the researcher derives the problems of fire protection in high-rise buildings construction sites and proposed the measures in such the legal aspects as fire building construction code and etc. There are the legal improvements such as orders of construction suspension in the problems of fire safety, appointing fire safety manager, temporary fire protection installation standards, enhancing penalty provisions regarding the use of fire, operating self fire brigade, confirming on-site after completing fire-protection facalities, establishment or strengthening special fire-protection investigations.

In recent years there has been considerable interest in the construction of super high-rise buildings. From the prior art, various procedures and devices for surveys during and after the phase of erection of a high-rise building are known. High-rise buildings are subject to strong external tilt effects caused, for instance, by wind pressures, unilateral thermal effects by exposure to sunlight, and unilateral loads. Such effects are a particular challenge in the phase of construction of a high-rise building, in as much as the high-rise building under construction is also subject to tilt effects, and will at least temporarily lose its - as a rule exactly vertical - alignment. Yet construction should progress in such a way that the building is aligned as planned, and particularly so in the vertical, when returning into an un-tilted basic state.It is essential that a straight element be constructed that theoretically, even when moving around its design centre point due to varying loads, would have an exactly vertical alignment when all biasing conditions are neutralised. Because of differential raft settlement, differential concrete shortening, and construction tolerances, this ideal situation will rarely be achieved. This paper describes a procedure developed by the authors using GPS observations combined with a network of precision inclination sensor to provide reliable coordinated points at the top of the worldwide highest-rise building under construction in Dubai.
