Although pilot projects have been actively carried out from 2017 to present to institutionalize CM at Risk, one of the major tasks for innovation in the construction industry, standards and processes related to Design VE, a key tool for determining GMP in the pre-construction phase, have not yet been established. Therefore, through research and operation status related to CM at Risk and Design VE, and survey on project participants' perception, the problem of the existing design VE process was derived, and the design VE process suitable for the CM at Risk project was proposed. The application plan was proposed in three aspects: Schedule, Cycle, and Process, and the appropriateness and applicability were verified through FGI. The results of this study are expected to be used as basic data on the establishment and legislation of order standards to be made in the future.

박보성,김옥규,Park, Bo-sung,Kim, Ok-kyue 한국건설관리학회 2021 한국건설관리학회 논문집 Vol.22 No.2

발주제도 혁신을 통한 국내 건설산업의 글로벌 경쟁력 강화를 목적으로 시작된 시공책임형 CM 사업이 공공부문에서 시범사업의 형태로 시행되고 있다. 그러나 정식 발주제도로 나아가기 위한 관련 법령 제정까지는 시간이 필요해 보이며, 사업에 대한 성과분석도 아직까지 미진한 상황이다. 이에 본 논문에서는 현재 시행되고 있는 4개의 시범사업의 사업이전단계사업관리(Pre-Construction Service)에 대한 성과분석을 통해 사업의 효과와 신뢰성을 검증하고자 하였다. Team Building, 설계도서 정합성, 공기검토, VE, BIM 활용 등 총 5개의 분야에 대해 성과분석을 진행했으며, 참여자 면담조사를 통해 문제점을 확인하고 그에 대한 개선안을 제시하였다. 본 연구의 결과는 향후 이루어질 발주제도 법제화에 대한 기초자료로 활용될 수 있을 것으로 기대한다. The CM at Risk project, which started with the aim of strengthening the global competitiveness of the domestic construction industry through innovation of ordering system, is being implemented in the form of pilot projects in the public sector. However, it seems that it is necessary to enact related laws and regulations to move to the formal ordering system, and the performance analysis of the project is still insufficient. In this paper, the effectiveness and reliability of the project were verified through the performance analysis of the Pre-Construction Service of the four pilot projects currently being implemented. The results of the study were analyzed in five areas including Team Building, Design Book, Construction Period, VE, and BIM. Through the interview survey, the problems were confirmed and improvement plans were presented. The results of this study are expected to be used as basic data for the legalization of ordering system to be implemented in the future.

Electrochromic devices (ECDs) have been drawing great attention due to their high color contrast, low power consumption, and memory effect, and can be used in smart windows, automatic dimming mirrors, and information display devices. As with other electronic devices such as LEDs (light emitting diodes), solar cells, and transistors, the mechanical flexibility of ECDs is one of the most important issue for their potential applications. In this paper, we report on flexible ECDs (f-ECDs) fabricated using an all-in-one EC gel, which is a mixture of electrolyte and EC material. The f-ECDs are compared with rigid ECDs (r-ECDs) on ITO glass substrate in terms of color contrast, coloration efficiency, and switching speed. It is confirmed that the f-ECDs embedding all-in-one gel show strong blue absorption and have competitive EC performance. Repetitive bending tests show a degradation of electrochromic performance, which must be improved using an optimized device fabrication process.

설계단계에서 적정 기계설비 공사비 산정을 위한 BIM 정보표현수준(BIL) 개선안

박보성(Bo Sung Park),김선혜(Sean Hay Kim) 대한설비공학회 2017 설비공학 논문집 Vol.29 No.12

Building information modeling (BIM) technology based on 3D modeling has been applied to the entire domestic construction industry since 2010. It can calculate quantity take-off considering construction productivity at design phase. Based on this, it is possible to improve the reliability of construction cost prediction of design phase in the process of cost estimation. However, Building Information Level (BIL) defined by Ministry of Land, Infrastructure and Transport and Public Procurement Service does not seem to offer doable environment due to the lack of detailed application items. By calculating construction cost that meets Construction Cost Estimate Accuracy by American Association of Cost Engineers (AACE) through quantity take-off and cost estimation based on 3D modeling of BIM technology, a BIL improvement proposal at design phase for Mechanical Contracts and Construction is provided here. Results showed that properties including outline and minimum specification of the main equipment, internal main piping, and internal main duct should be defined from the intermediate design phase to have reliable cost estimation.

주파수 공유기법 SDR 플랫폼 통해 C-ITS 네트워크 간섭 대안 제시

박보성(Park bo sung),정준영(Jeong jun yeong),지승한(Ji Seung-Han) 한국정보기술학회 2020 Proceedings of KIIT Conference Vol.2020 No.10

본 논문은 궁극적인 목적은 C-ITS를 통해 간섭으로 인한 보안,에러 등근본적인 해결방안 제시하는 것이다. 현재 국토교통부가 자율주행차량의 한계 극복을 위한 도로 인프라를 혁신과제로 추진하고 있는 C-ITS 성공적 추진을 위한 함의를 제시하고 한다. 실현이 되면 교통문제를 해결하며 국가적으로 안정성 및 효율성 향상시켜 사회 전체 파급효과 큰 분야이다. 스마트시티내에서 C-ITS를 수행하기 위해 RFID, 5G, AI(인공지능), 주파수 공유기, Cloud, Bigdata, Mobile과 같은 정보통신기술의 융합이다. C-ITS 목적은 완전 자율주행을 만들자는 것이다, 하지만 실현하기 위해 쉽게 달성이 어렵다. 대표적으로 C-ITS에서 V2X 통신기술을 사용한다. V2X에서 ‘주파수 간섭’이라는 문제점이 있어 주파수 공유화를 통해 해결해야 한다. 주파수 공유법에서 SDR 방식과 CR방식이 있다. CR 방식에서 정부에서 기업간에 주파수대역을 공유하는데 사실상 실현하기 어렵다. 실현가능한 SDR 주파수 기반인 근거리전용무선통신(DSRC)을 통해 융합하여 신속하고 능동적인 돌발사항 사전대응 및 예방할 수 있는 효율적인 교통체계 방안을 제시하고자 한다. The ultimate purpose of this paper is to present a fundamental solution of security, error, etc. caused by interference through C-ITS. Currently, the Ministry of Land, Infrastructure and Transport presents implications for the successful implementation of C-ITS, which is pushing for road infrastructure to overcome the limitations of self-driving cars as an innovation task. If realized, it will solve traffic problems and improve stability and efficiency nationwide, which will have a great ripple effect on society as a whole. It is a convergence of information and communication technologies such as RFID, 5G, AI (Artificial Intelligence), frequency sharing devices, Cloud, Bigdata, and Mobile to carry out C-ITS within smart cities. The purpose of C-ITS is to create a full autonomous driving, but it is difficult to achieve easily to realize it. Typically, C-ITS uses V2X communication technology. There is a problem with" frequency interference" in V2X and should be solved through frequency sharing. There are SDR method and CR method in frequency sharing method. Under the CR method, it is virtually impossible for the government to share frequency bands among companies. We would like to present an efficient transportation system that can converge through near field radio communication (DSRC), which is a feasible SDR frequency base, to respond quickly and actively to and prevent unexpected events.

국내 공공부문 시공책임형 CM 사업자 선정을 위한 평가방식에 관한 기초연구

박보성 ( Park Bo-sung ),이태형 ( Lee Tae-hyeong ),방홍순 ( Bang Hong-soon ),김옥규 ( Kim Ok-kyue ) 한국건축시공학회 2018 한국건축시공학회 학술발표대회 논문집 Vol.18 No.1

The construction liability type CM has been introduced in the form of a pilot project through public institutions since 2017 since it was introduced in the term of construction responsibility type construction project management in the Basic Law of Construction Industry in 2011 with the aim of improving the constitution of the Korean construction industry and strengthening global competitiveness. Through the introduction of construction-responsible CM, the government intends to change the paradigm of the overall construction industry, including design and construction, construction costs, disputes between stakeholders, and transparency of business. In this regard, the study aims to compare and analyze the evaluation methods on the bidding guide that public institutions (LH) are currently using to select companies in order to lay the foundations for successful construction of construction-responsible CM ordering methods.
