According to the recent "Status of Industrial Accidents at the End of December 2020" released by the Ministry of Employment and Labor, each industry is subject to industrial accidents. The number of accident deaths by construction industry, accident deaths by accident type fell, and accident deaths by workplace size were 5 to 49, indicating that most accident deaths occurred due to falling accidents at small construction sites. Therefore, urban living houses are small construction sites, and the probability of falling accidents is very high. Fall simulation training for disaster occurrence is conducted mainly by large construction ordering organizations in the public sector, and it is the first case in Korea that a housing construction company has conducted at a small construction site. This study analyzed and presented the definition, construction characteristics, and safety management status of urban living houses, and developed and spread an emergency relief procedure manual in the event of a fall accident to minimize deaths.

근로기준법상 법정근로간은 1일 8시간, 주40시간입니다. 정부는 4월 14일부터 인사혁신처를 시작으로 금요일 조기퇴근제를 실시할 예정이라고 하는데요. 주40시간 범위내에서 월~목까지 매일 30분씩 연장 근로하는 대신 한달 중 금 1회 오후 4시에 조기퇴근하는 방식으로 운용될 예정이라고 합니다. 공공기관에서는 이미 유연근로시간제가 실시되고 있는 사업장도 있고 별도 연장 근무 없이 Family day 또는 culture day 등으로 명명하고 월 1회 조기 퇴근하는 제도를 운용하고 있기도 합니다. 기존에 자율적으로 기업형편에 따라 실시되었던 유언근로시간제와 더불어 금 조기퇴근제도는 공기업을 중심으로 좀 더 확대될 것으로 보입니다. 다만 국가공무원법이 적용되는 공무원과 달리 민간부문에서 유연근로시간제도를 도입하고자 할 경우에는 근로기준법을 준수하여야 하므로 법률에서 정한 유연근로시간제도의 유형에 따라 취업규칙의 변경 또는 근로자대표와의 서면합의 등의 절차를 거쳐야 합니다. 금요일 4시 조기퇴근제도는 탄력적 근로시간제도의 일 유형이라고 볼 수 있기에 이번 호에서는 탄력적 근로시간제도에 대해 알아보고자 합니다.

In the current domestic design-build contract, design and construction are separated due to prohibition of outside work. but instead the design-build contract adopts a method of fulfilling each assignment as a joint venture, which makes it difficult for participants to communicate each other and often require changes of design. also, It is difficult to performance efficiency project that they don't want to share useful information related to design and construction. In this study suggests how to maxmize the effiency of the project by proposing a process model connected with an efficient partnering and constructability in a deign development phase of design-build constract.

'08.3월 U-City법이 제정되었고, '09년에 U-City법에 근거한 제1차 유비쿼터스도시종합계획 (이하 U-City종합계획)이 수립되었다. 이후 계획에 따라 U-City R&D, U-City시범도시 지원사업 등이 추진되었으며, 기술, 서비스, 인력양성, 산업지원, 법제도 개선 등 다양한 부문에 U-City 지원 정책이 시행되었다. 이로 인해 국내 U-City 사업이 활발히 추진되었으나 주로 공공 주도의 신도시를 중심으로 구축되어 과도한 건설비용 및 관리운영비 부담, 중복투자 등의 다양한 문제를 발생하게 된다. 결국 신도시 조성 개발이익을 통한 U-City 구축은 건설경기의 침체와 함께 심각한 위기를 맞게 된다. 하지만 새정부 출범 이후 U-City는 창조경제 대표사업으로 채택되어 재도약할 수 있는 계기가 마련되었고 정부는 지역경제 활성화의 일환으로 도시재생사업에 U-City를 접목하는 등 U-City 부흥을 위한 시도를 지속적으로 하고 있다. 특히 신도시 개발로 치우쳐서 발생된 기존도시와의 불균형을 해소하기 위해 다각도로 해결방안을 모색하고 있다. 이에 현 시점에서는 기존도시에 초점을 맞추어 U-City 방향을 살펴보는 연구가 필요하며, 기존 신도시형 U-City가 추구했던 정보통신 위주의 계획에서 벗어나 지역특성 및 수준 등을 고려한 도시계획적 측면으로 접근하는 것이 바람직하다. 본고에서는 국내외 스마트시티 동향을 파악하고 우리나라의 신도시개발형 U-City 구축 현황의 문제점을 진단하여 기존도시형 U-City 구축의 필요성을 도출하였다. 이를 토대로 실효성 있는 기존도시 U-City 구현을 위하여 도시계획적 관점에서의 고도화 방안을 모색하고자 한다.

On 1 July, 2000, the Ministry of Construction and Transportation announced the Earned Value Management System(EVMS) will be applied in public sector soon. However the arguments over the EVMS applied to our unique construction environment still exist and create strong concerns and worries among some experts it would be another mistakes proposed by the government. We do know the EVMS comes from C/SCSC which was first released by the United States Department of Defense in December 1967, and proved very powerful and efficient project management tool from a lot of practices. Although it is an excellent tool, we can not ignore our many experienced failures appling foreign system due to the differences of construction culture and law between the Korean and US construction industries. The purpose of the EVMS's success in Korea, therefore, this paper tests and proves the EVMS's adaptability and credibility to our construction environment by EAC model, that is one of the most important functions in the EVMS, using very scare EV data of the Korean construction projects.

The amount of new apartment construction has been trending upward in 3~4% each year since 11% increase in 2002. Currently, in public apartment construction sites under separate delivery system for construction waste processing, the significant difference between estimated quantity for contract and actual amount frequently causes severe controversy among project participants. Many factors such as poor environmental management, inadequate contractual amount are assumed to influence the above problem, and the requirement to revise existing generation rates, the key criteria applied in estimating the quantities of waste, is increasing. Most of generation rates were established in early 2000's, and have difficulty in reflecting the changes from new materials and technologies accordingly. Therefore, this study aims to clarify the types of construction waste for each trade and the forecast method as preliminary work in order to develop more accurate generation rates for construction waste in new construction. To achieve this purpose, the architectural bills of quantities in ten apartment projects executed during 2010~2013 were collected, and the possible waste types and reasonable material loss ratio for each item from temporary works to owner-supplying material area were defined and compared through the workshops and interviews with the experts and on-site environmental managers. The results of this study will contribute to establishing the categories of construction waste for construction trades and proper generation rates by the indirect estimation method in new apartment construction in the follow-up study.

The domestic CM business market has continued to grow, but its size is relatively small yet in comparison with the total size of the domestic construction industry. Evaluation of CM projects was conducted through questionnaire surveys. Both clients and CM firms showed positive satisfaction levels. Nevertheless, the clients' satisfaction levels were relatively low in safety management, cost management, and document and information management. Superior areas of CM tasks were time management and recovery scheduling, quality control and technical instruction, and design value engineering. On the other hand, inferior areas of CM tasks were claim analysis and dispute resolution, cost estimation, and life cycle costing. Both entities have agreed with the positive effects of CM involvement in terms of cost saving, time reduction, quality improvement, and safety incidents prevention to at least 0~5% extent.

This research has been accomplished to build up the growth strategies of Kangwon district's small & medium-sized construction firms. For this purpose, we made an investigation of the present situation and status for existing regional small & medium construction firms by analyzing data. Based on the results from this study, the following growth strategies are suggested to gain their competitive advantages. Firstly, most of all, the role of the top manager is the most important factor since most of the top manager for the small & medium-sized construction firms coincide with the owner the firms. Secondly, the specialization strategy is to establish. Above all they concentrate their business capacities on core business. Then, this growth strategy should be based on the selective escalation of functions in order to maintain an appropriate level of construction works. Thirdly, the specialized skills and skilled workers are ensured for competitive advantages. For human resource development, they should train workers to be multi-functioned on the assumption the they could stay at firm until they wish to retire. Finally, the government must also spare no effort to encourage the small & medium-sized construction firms to build up it's competitive power and cultivate it's spontaneous generation power though the reformation of system related whit the small and medium construction industry.

The government wants to apply the construction cost estimating method based on historical data published in the first six months of 2004. Construction companies, however, require the proposed cost estimation model, to be improved which makes it difficult to predict a reasonable construction costs. This paper presents an improved historical data selection model after analyzing the problem of previous method throughout comparing contracted unit prices of reinforced concrete works selected by the previous model to market prices. The model which can select more feasible data would assist participates such as general contractors and sub-contractors to earn a proper profits.
