Recently, the construction industry is increasingly in need of securing safety rights due to repeated serious accident. Accordingly, the government enacted the "Serious accident Punishment Act" to strengthen punishment for serious accident and expand the scope of punishment. However, safety managers in the construction industry are still vulnerable to safety accidents due to the heavy workload. The purpose of this study is to increase the efficiency of performance tasks and reduce serious accidents in the construction industry through analysis of performance tasks by stages of construction projects. The tasks derived through domestic research and domestic and foreign system analysis were classified step by step to analyze the correlation between difficulty and preventive effect, and inefficient tasks were discovered and improved. This can be used as basic data for identifying safety management tasks and preparing effective safety prevention measures, and it is expected to be a preventive measure against industrial accidents in the construction industry by using it for efficient work reorganization by safety managers.

The image data of the web camera is used to identify the construction status of the site in a remote office and it can be used for safety management. This study develops a construction schedule simulation system based on the active nD object linked with real image data of web camera from the construction site. The progress control method by 4D object uses a method that the progress of each activity is represented with different colors by progress status. Since this method is still based on a virtual reality object, it is less realistic description for practical engineers. Therefore, in order to take advantage of BIM more realistic, the real image of actual construction status and 4D object of planned schedule in a data date should be compared in a screen simultaneously. Those methodologies and developed system are verified in a case project where a web camera is installed for the verification of the system.

The sponge city construction is being carried out in China, and how to reasonably determine the scale of the sponge city facilities is a key point that the planners and designers should seriously solve. In this paper, taking determination of the sponge city facilities in a residential building in Shenzhen as an example, the layout and scales of the rainwater tanks, raingardens, ecological roofs and permeable pavements are decided by using the volumetric method and stormwater management model (SWMM). The calculated results by the two methods are compared and analyzed. The results show that the scales of the sponge city facilities determined by the two methods are almost the same, and it means that any method can be used to determine the scale of sponge city facilities. The volumetric method is relatively simple, and it is suggested to use to determine the scale of sponge city facilities during planning stage. While SWMM is more complex and requires a lot of input conditions, but it can provide the reduction effects of the sponge city facilities for rainfalls with different recurrence periods. Therefore, SWMM is recommended to use the calculation of the hydrological process of the sponge city facilities during the design stage.

국내 건설산업이 새로운 도약을 이루기 위해서는 해외 시장에서의 경쟁력 확보와 새로운 시장의 창출이 필요하다. 국제적인 기술경쟁력을 가진 건설 분야와 IT 분야의 융합기술 개발을 통한 국제 경쟁력 확보와 새로운 시장창출은 성공가능성이 매우 높게 평가된다. 그렇지만, 구체적인 실현에 있어서 기술적 장벽뿐만 아니라, 융합개발의 명확한 모델이 정립되어 있지 않기 때문에, 건설 산업 관점에서 융합기술의 가능영역과 적절한 개발모델의 제시가 요구되고 있다. 건설 분야의 IT 융합기술은 생산성 향상과 노동력 절감 및 유지관리 구조물의 생애주기 비용절감을 통한 경쟁력 강화 분야와 u-city와 같은 수요창출형 신상품의 개발로 구분될 수 있다. 특히, IT 융합기술 개발 단계에서 건설사 관점에서 철저한 수요중심의 접근과 빠른 IT 기술발전에 대응하는 전략이 요구되며, 융합개발의 주도그룹을 선두로 선순환적인 순환모델을 적용하는 전략이 효과적일 것이다.

최근 건설 공사의 규모가 대형화되고 건설 산업의 환경 변화가 빠르게 진행됨에 따라 이에 대응하기 위한 방안으로 건설 산업의 정보화가 중요한 이슈로 대두되고 있다. 이는 정보화 기술의 발달과 타 분야에 비해 건설업의 정보 인프라가 상대적으로 떨어진다는 점도 중요하게 작용하였다. 이러한 점에서 현재 건설업에 정보화를 도입하기 위하여 다양한 분야에서 연구가 진행 중에 있으며 이러한 건설 정보화의 중심에는 3D CAD의 객체 정보가 부각되고 있다. 그러나 설계 도구로서 뿐만 아니라 그 기능의 확장성에 비해 3D CAD는 실무에서의 활용 정도가 매우 저조한 실정이다. 그러므로 본 논문에서는 실무에서 3D CAD의 활용 저조에 대한 원인을 AHP 분석기법을 통해서 고찰해 보았다.

With the tunnel to case of the construction slope it executes the periodic maintenance due to an objectivity standard. But, the standard connected with construction slope is not integrated with the important public paper organic enemy and it is duplicated and the standards which conflict are being scattered. Also, it is referred to some specifications simply and the feature which is diffuse appears. Therefore, there is a necessity which it investigates the problem point of the maintenance civil official and it improves rationally and it takes a triangular position a confusedly be standard system. In this research which it sees accomplished the fundamental research against the inspection item classified by reinforcement method for the construction slope maintenance.

Floats are used by the parties involved in a construction project. The owner may use float by changing order(s) or by executing risk avoidance plan; the contractor may use it for leveling resources or substituting activities' construction methods to reduce costs. Floats are accepted either just as by-product obtained by critical path method(CPM) scheduling or as asset having significant value. Succinctly, existing studies involved in float value does not consider its' changes on project time domain. It is important to identify float ownership and to quantify its' corresponding values. This paper presents a method that quantifies float value of money that changes over project execution. The method which accurately computes the monetary value of float may contributes to resolve conflicts relative to float ownership and/or delay issues among project participants. It compares the difference between the monetary value of total float - on non-critical path in each and every schedule update. It makes use of critical path method (CPM) and commercial software with which practitioners are already familiar.

우리나라 건설산업의 환경은 IMF를 기준으로 급격하게 변화하였다. IMF 이전에는 정부의 제도적인 보호막과 일부 관행으로 인해 안정된 환경을 보장받아왔으나 최근 대형 공공공사의 발주물량의 감소와 더불어 시장예측의 불확실성 증대, 공공 공사의 효율화 및 투명성 제고를 위한 입 $\cdot$ 낙찰 제도의 개선, 업체의 급격한 증가 등의 이유로 건설업계 경쟁은 더욱 치열해졌다. 이러한 경쟁의 심화는 조직구조가 취약하고 기술, 자금 등 경영자원이 부족한 중규모 건설업체가 환경변화에 신속히 대응하고 원가 절감 및 생산성 향상을 위한 지속적인 투자와 건설시장에서 살아남기 위한 전략수립을 요구하고 있다고 할 수있다. 따라서 본 연구에서는 중규모 건설기업을 대상으로 경영학의 산업구조분석 이론인 전략군 분석 이론을 응용하여 경쟁기업들 중 유사전략을 취하는 군집별 특성을 도출하여 제안함으로써 이를 통해 자사와 경쟁사의 경쟁영역 및 상대적 위치를 파악하고 미래 전략방향 결정을 위한 기초 자료로 활용될 수 있게 하고자 한다.

Although much research has been conducted to identify the influence of culture on conflict management and resolution behaviours in organizational settings, no study has been done yet in the construction industry particularly in considering the influence of individual level individualistic and collectivistic values. Despite the key role of self-construal in explaining or predicting behaviour in interpersonal conflict, it has not received enough attention in construction management. Reflecting this necessity, the objective of this exploratory study was to establish, through the application of the Rahim Organizational Inventory (ROC II) instrument, how the cultural values of professionals of construction businesses relate to the application of different conflict-handling styles through self-construal. Data were collected using questionnaire surveys from construction professionals working in contracting firms. The findings illustrate the importance of self-construal type as an individual-level cultural variable in explaining the differences in the style of handling interpersonal conflict in the context of the construction industry.

Construction project is completed through several stages and problems of each stage affect directly not only now but also next. Defect of 2D drawings influence in construction phase, and it make many loss on project. Nowadays we practically use real Mock-up test in construction sites to solve the problems. But it also has many problems which are waste much money and time. Therefore, this study tries to analyze effect that is occurred by appling BIM Mock-up simulation instead of real Mock-up execution. These analysis is conducted by comparing two construction building site. These have same shape but one is made for BIM Mock-up, and another is real Mock-up. Comparison points of view are cost, time and operator's satisfaction. It is expect that BIM Mock-up is more effective at low cost and on shorter time. But our analysis show that each are conducted different part of function. So new Mock-up type is required. Hybrid Mock-up is combine real mock-up with BIM simulation and it can minimize risk of project.
