강교량 가설공사의 설계는 그동안 과거유사사업의 자료를 토대로 설계자의 경험에 의존하여 진행되어 왔다. 이로 인해 실제 현장에서 소요되는 가벤트에 대하여 과대설계 논란이 있으며, 시공단계에 불필요한 설계변경을 야기하고 있다. 본 연구에서는 강교의 설계작업 과정에서 생성되는 설계 자료와 가설공사의 수행에 필요한 자원에 대한 데이터베이스를 구축하여 강교 설치 가설공사의 최적화설계 지원 시스템을 개발하였다. 이를 통하여 가설시설물에 대한 설계를 최적화하며, 설계변경을 줄이는 데에 기여할 뿐만 아니라 설계정보를 시공단계에 활용하게 함으로써 업무의 효율성과 정확성을 제고하였다.

Temporary work that utilizes temporary equipment (e.g., system scaffold and system pipe support) in construction work is one of the most vulnerable work from a safety perspective in South Korea. Typically, temporary equipment is reused at construction sites. The Korea Occupational Safety and Health Agency announced guidelines regarding the performance standards for reusable temporary equipment to prevent the accidental collapse of temporary facilities. Nevertheless, temporary facilities' collapse still occurs, which could be attributed to a degradation in the performance due to the reuse of temporary equipment. Therefore, this study investigated the performance of simple temporary structures assembled with new and reused equipment. To this end, an experimental module was designed based on previous research cases, and two experimental models were constructed, in which one was assembled using new equipment (Model A), and the other was built using reused equipment (Model B). To determine the performance of each model, a load test was conducted to measure the maximum load that each model could withstand. The experimental results revealed that the maximum load of Model B was 15% lower than that of Model A. This indicates that there is a meaningful performance difference between those two models. Based on this result, the authors decided to perform additional tests with more realistic models than previous ones. The new experimental module was designed to ensure compliance with the Korean design guidelines. In this presentation, the authors show details of the first tests and their results and plan for the additional test.

건설 프로젝트의 초기단계에 타당성을 검토함에 있어서 공통가설공사의 경우 설계도서상에 표시가 되지 않거나, 시방서상에 간략하게 서술되어 있기 때문에 담당자의 경험 의존율이 다른 공종에 비해 높다. 이런 초기단계의 결전은 프로젝트의 진행과 더불어 많은 문제점들을 야기 시킬 가능성이 있다. 따라서 최근 활발히 논의가 되고 있는 기존 공사정보에 대한 실적 데이터베이스와 공통가설공사의 분류체계를 포함한 시스템을 개발하여 자료들을 분석, 활용함으로써 시공전(Pre-Construction) 단계의 공통가설공사에 대한 작업 및 원가 예측을 용이하게 하고, 후에 Feed Back 됨으로써 정확한 건설 프로젝트 타당성 분석을 가능케 하고자 한다.

Since 1990 in South Korea, the considerable concern for the safety of construction sights has been increased due to serious accidents. There have been numerous big improvements in preventing the accidents by strengthening legal enforcement and by continuing to emphasize the safety management. Further, the safety standards and criteria for temporary constructional work have been enacted and established in order to maintain safe work environments in temporary construction and structure settings. However, the death rate from fall accidents is still high in the temporary constructional and structural settings in comparison to other work places in construction. According to the analysis of accidents in the field of construction between 2000 and 2007, the death rate from fall accidents in the temporary constructional settings was highest. In addition, there have been more fall accidents in the work setting by small or medium construction enterprises rather than large enterprises due to the relative lack of the safety management. Thus, in this study, the analysis of the causes of fall accidents in the temporary constructional and structural settings between 2000 and 2007 was conducted. Moreover, a survey study was carried out in order to investigate further causes based on the analysis. Finally, this study was also conducted in order to provide basic information and knowledge about the prevention of future accidents.

The use of temporary container classrooms has increased in recent years due to the development of the construction industry and renovation or rehabilitation of schools. Therefore, various problems, such as errors during assembling, design and insulation issues, and noise problems, have surfaced during the construction of temporary container classrooms. This study analyzes the causes of assembly errors during the manufacturing and installation processes to improve the quality of temporary container classrooms. Assembly errors are caused by non-level planes and inaccurate cutting during the manufacturing process. In the installation process, poor leveling is a major factor that causes errors during the assembly of temporary container classrooms. These causes result in uneven horizontal or vertical planes and uneven height. To solve these problems, quality improvement measures, such as pin connection, jig, joint coupling, and surface plates are proposed in this study.

This study has been reorganizing a standard breakdown structure of temporary technique focused on construction site. For this, first of all we, the authors, reviewed features and present statuss of construction temporary technique, and could develop to the standard breakdown structure through studying a construction site and researching a delphi method. By using the standard breakdown structure obtained from this study, it is expected that the application of to information of construction business and plan to a schedule and a work.

가설공사는 임시시설물이지만 공사기간동안 사용빈도가 높으며 공사비의 10% 내외를 차지하고 있어 체계적인 관리가 필요하다. 하지만 가설공사의 시공검측정보들은 설계도서 및 시방사항에 특별한 명시가 없는 경우가 많으며 제기준에 대한 사항도 방대하다. 이로 인해 가설공사에 대하여 품질점검을 실시할 경우 관련 점검업무들을 비효율적으로 수행하며, 인간적인 오류가 발생할 확률이 높다. 따라서 본 연구에서는 가설공사에 대하여 품질점검 업무수행을 지원하고 관련 정보를 제공할 수 있는 전자작업지원시스템을 적용하고자 한다. 이를 위해 IDEF0를 활용하여 업무 단위프로세스별 정보흐름을 규명하고 EPSS기반 품질점검 업무체계를 정리하여 프로토타입을 개발한다. 이후 현장적용을 통한 검증방법으로 가설공사 품질점검 업무의 효율과 정보접근성을 향상하고자 한다.

Construction work is affected by the weather; e.g. snowfall, rainfall and low-high ambient temperature, especially at a site in a severe climate. The influence of the weather is one of the possible reasons for delays in a construction schedule and quality deterioration. To protect the worksite from severe weather conditions, the temporary roof and wall could be installed on the outside of main structures designed in advance and the temporary structures could be took down after a period use. The greater coverage all-weather construction method is applied, the larger the effect. so, it is important and needs that the temporary roof and wall can be widely applied, designed to effectively about structure and layout.

The purpose of this study was to analyze the types and characteristics of space construction in temporary small-sized housing for single-person household through the understanding and interpretation of the modern flexible lifestyle. A document research method and case studies were used to analyze and classified the spatial characteristics of temporary dwelling spaces since 2000. Findings of the study were as follows: In order to conform the concept of temporary dwelling for small-sized housing units of single-person households, the types and characteristics of space construction were divided into three aspects: (1) 'Transporting' by wheel, rotation and vehicles, (2) 'Transforming' by adapting, assembling disassembling, and folding unfolding, (3) 'Wearing Carrying' by inflatable and tented type. In conclusion, this study found two types of space construction in temporary small-sized housing. The first was 'formal aspect' which was focused on the simplicity of shape, ease of deformation and lightweight of materials. And the second was 'functional aspect' which was focused on the complex space composition, the rapidity of installation and dismantling, ease of movement and transportation. This study shows that the combination of two types of the temporality will be more ideal in temporary small-sized housing planning rather than relying on just one type.
