건설사업과 환경보전은 대립적인 요소를 많이 가지고 있어 건설사업으로 인한 환경 분쟁이 급증하고 있으며 소음 $\cdot$ 진동에 관한 분쟁이 대부분을 차지하고 있다. 이러한 분쟁과 민원은 기업에 대한 부정적 이미지, 사업의 지연 $\cdot$중단, 배상액 지불 등 막대한 경제적 손실을 가져오므로 치밀하게 관리할 필요가 있다. 본 논문에서는 문헌조사를 통하여 이론적인 고찰을 실시하고, 소음 $\cdot$진동 관련 법령을 정리 분석하여 건설사업과 관련된 검토항목을 추출하였다 또한 사전 환경성 검토 환경영향평가 항목과 분쟁조정에 관한 통계자료를 검토 $\cdot$분석하여 건설사업의 추진단계별 소음 $\cdot$ 진동 관리방안을 제시하였다 이는 건설사업을 수행함에 있어서 소음 진동에 관한 규제사항의 정확한 준수와 분쟁 및 민원의 발생을 최소화하는데 활용될 수 있을 것이다.

국내 건설생산체계는 설계단계에 시공성의 반영이 어려워 시공단계에서 많은 시행착오와 잦은 선계변경이 요구되고 있다 특히 불확실성이 높은 도심지 건축될, 그 중에서도 초고층 복합 건물 프로젝트의 경우, 시공과정을 반영한 설계의 중요성은 더욱 중요한 요소가 된다. 본 연구에서는 국내 정보분류체계를 근간으로 기초조사를 통하여 현장의 시공계획에 필요한 데이터를 수집 이를 시스템화 할 수 있는 방안을 모색하였다. 또한, 이를 본 시스템에 적용하여 3D CAD와 공사 계획 및 시뮬레이션 시스템으로 공정 시뮬레이션 및 타워 크레인 시뮬레이션을 구현하여 초고층 공사 수행시 발생할 수 있는 문제점을 미리 검토 및 해결하여 초고층 프로젝트 공사의 합리화와 생산성 향상을 위한 공사관리시스템을 실제 프로젝트에 구현하였다.

In this paper we introduce 6-fold symmetry crystal growth using new phase-field models based on the modified Allen-Cahn equation. The proposed method is a hybrid method which uses both analytic and numerical solutions. We then show this method can be extended to $k$-fold case. The Wulff construction procedure is provided to understand and predict the shape of crystals. We also present a detailed mathematical proof of the validity of the Wulff construction. For computational results, we verify the accuracy and efficiency of the method for snow crystal growth.

This report is to do design management for constructability review of high quality exposed concrete, which is used increasingly in recent. To secure systematic management at design phase, we reviewed each definition and work at each design phase, we define high quality exposed concrete, a part of architectural concrete, as "an exposed concrete which has well ordered joint & is in pursuit of smooth surface." We reviewed requirements and influential factor to obtain High quality finishing surface and compared construction process of high quality exposed concrete with that of other finishing method. Management method at each design phase for constructability review to meet additional works and requirements is presented.

As the needs for the mega-sized, high-rise and irregular shape of building increase, domestic application of BIM in construction industry is increasing in recent years. In this circumstance, interests in BIM modeling and modeling detail level have been also increased. BIM that is based on a three-dimensions, requires a specific and precise building expressions. And model expression level required for each phase such as design, construction, and maintenance of the construction project could be different as its needs. Because that it is not clear to define the criteria for the expression level of construction BIM model, It is difficult to decide how detail and what to model is appropriate in the practical application of BIM model. It could be the reason why the productivity in construction project became lower and lower. In this study we consider the way how to improve the productivity of BIM and analyze the appropriate representation level of construction BIM model through the experts' survey. The results of study could suggest the basis for an appropriate expression level of construction BIM model.

As robotic technologies have become more actively utilized to automate many construction tasks, they have been able to improve the construction productivity, quality, and worker's safety on site. A new advanced system, Robot-based Construction Automation (RCA) system, is currently being developed. To accomplish RCA system effectively, Design for automation (DFA) should be performed in automation system developing phase. The performance criteria of this system are a major cause of design changes. It is required exhaustive review for development new system. This research analyzed the design changes of Climbing Hydraulic Robot system and Construction Factory (CF), being currently developed in the field of applied RCA systems. And the design change matters according to performance criteria in each system's design-by-step were analyzed. The purpose of this research is developing the performance criteria in the developing phase of RCA system, and then will be served as basis for system design in similar projects.

The construction work to establish a safety management plan should be carried out Design for Safety(DFS) task by the designers from May 2016 according to the amendment of the Construction Technology Promotion Act. However, designers lack experience in construction work and lack of information on safety accidents, so it is not easy to predict a disaster that may occur during the construction phase. Therefore, the purpose of this study is to provide information about disasters that can occur in each construction work in order to enable designers to efficiently perform DFS task in the design phase. In this study, the construction work was classified by work unit and the disaster risk assessment was conducted using the Failure Mode and Effect Analysis technique. The disaster information by work unit analyzed in this study can be used to provide designers with an alternative to prevent disasters at the design stage. Disaster information by work unit of apartment construction can be used by designers to prepare an alternative for disaster prevention at the design stage.

Turn-key and CMF(CM for Fee) have been selected as procurement paths of large public projects in Korea. However, recently, researches and discussions on CMR(CM at Risk) have been popular as the Korean government seeks for alternative procurement paths to enhance the performance. In the CMR projects, the part who is responsible for construction management should predict and control the potential risks for guaranteeing benefits. In this paper, CMR projects in which a general contractor plays the role as CMr is mainly analyzed. We give attentions to risk management during construction process given that subcontractors, main parts in this phase, work in various ways and thus more chances for faults exist. In this case, for the general contractor, to recognize potential risks in previous to start construction works of subcontractor by means of virtual design and construction (VDC) must be essential to this end. The case study of practices on VDC in U.S in which CMR has been introduced can provide considerable aspects to implement it in Korea.

In Japan, the population progresses to the extreme aging society and it is entering the phase of the population decrease while the population increase is continuing in the world. The construction market is expected to shrink accordingly, however the situation of labor shortage is expected to continue at a faster rate, because the aging of construction workers is progressing and new younger labor force cannot be secured. In order to supplement the labor shortage, it is required to progress mechanization, automation, labor saving, and efficiency improvement by utilizing the information well in each stage in a series of flow of planning, design, construction, operation, and disassembly in one building. The measures to maintain and expand the construction market by the new efficiency improvement techniques which enhance the utilization degree of building information are required. Currently, the elemental technologies which utilized BIM (Building Information Modeling) are accumulated by advancing digitization in each phase. DX (Digital transformation) in the construction industry can be achieved by the technology maturing and having a series of continuities. It is anticipated that this will evolve to a new method which is unprecedented. Present status of BIM and mechanized constructions in Taisei Construction are introduced, and future prospect is described.

Because of variable factors in construction phase, measurement of carbon emission in construction industry is more difficult than in other industries. To enhance accuracy of the measurement, the impact of variable factors must be considered. In this paper, to understand the influence of variable factors in steel erection work, a carbon emission casual map was developed. The map demonstrates that the considerations of variable factors in measurement of carbon emission improves the accuracy. The results of this paper are expected to contribute to development of carbon emission casual map and carbon emission measurement model for the entire construction phase.
