  • 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.

  • 본 고에서는 기존 미진동파쇄기류(미진동파쇄기, 플라즈마 등)의 단점인 시공성 및 경제성을 개선하고, 발파진동을 최소화한 미진동화약(NewFINECKER)의 개발 및 현장적용 사례를 소개하였다. 이 미진동화약은 국토해양부 표준발파패턴중(中) Type-1(미진동굴착공법, 125g 미만의 폭약 사용)에 부합하며, 지발발파가 가능하고, 시공성 및 작업효율을 대폭 개선하는 반면 진동수준은 일반 에멀젼폭약(NewMITE)의 약 60~70% 수준으로 나타났다. 추가적으로 현장 적용시 표준발파패턴, 발파진동추정식, 시공방법 등을 본 연구에 제시하였다.

  • The purpose of this study was to verify fitness of a new raglan sleeve pattern according to the result of appearance and function evaluation. Also, it was to search the relation between the construction factor and the function on the selected 3 types of the existent raglan sleeve patterns and the new sleeve pattern. Three female university students having different shoulder shapes were selected as subjects, wore 4 different types of the raglan steeve was evaluated by professional panel. The functions of the evaluated sleeve patterns evaluated was made by the wearer themselves. According to the comparison of the new raglan sleeve pattern with the existent raglan sleeve pattern, the new raglan sleeve pattern acquired the higher evaluation scores both on the appearance test and the function evaluation. It was known that the appearance and function of the raglan sleeve pattern were effected by construction factors of the sleeve pattern.

  • In this paper we make use of the parity check matrices of the codes based on inverting construction $Y_1$ to construct a number of new asymmetric orthogonal arrays with higher strength and higher number of levels using the method of construction of asymmetric orthogonal arrays given by Suen et al. (2001).

  • For the construction safety manager, it is expected that job stress is significantly high due to lack of expertise about new technology, new construction methods, and enlargement of scale as well as due to work intensity and unstable work hours. It is probable that such an increase in job stress not only has bad effects on individual, but also the bad effects spread to construction industry at large, resulting in rise in accident rate, increase in direct and indirect loss cost, and loss of reputation. In this context, methods for controlling construction safety manager's job stress are needed at the levels of both government and company. Therefore, this study investigated and analyzed the effects of construction safety manager's job stress on job satisfaction and job commitment, and proposed methods for relieving job stress. In addition, this study was suggested policies for higher job satisfaction and job commitment at the levels of the government and companies.

  • Owing to the deregulation, low interest, sufficient liquidity and etc., the real estate market has been recovered in some areas and some investment products to the degree being concerned about the overheating. In order that the construction and real estate industries, which play the considerable role in our economy, may be soundly grown toward contribution of the stable growth of our economy, it is being requested to acquire the transparency, predictability and trade stability of the international level conforming to the deregulation during the sale in lots of the building. For this reason, keeping pace with the trend of the construction industry and the current of the society, which are more and more large-scaled and globalized, it will be necessary to solve the social matters and to construct the more efficient and continuous construction management by widening and activating the field of CM through scheme of more specialized, sustainable and general CM method and establishment of new business bounded system in the construction management.

  • 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 scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.

  • New Fabrication Facility (FAB) construction is performed with Building Information Modeling (BIM) based design. The BIM design data keep updated during the FAB construction. To improve fast-track construction management, a Fabrication Facility Augmented Reality (FABAR) was developed. This study introduces a FABAR system development process and shows performance evaluation results of the FABAR prototype system. The FABAR is implemented with three major modules: Augmented Reality (AR) visualization unit (Room-box) to transfer big BIM data to AR data, AR registration and tracking unit to match AR with real scape and to keep AR coordination in real, and AR data management unit to enhance usability. The prototype performance results were as follows: visualization of design BIM data via AR within 24 hours, precise AR registration and tracking registration, and appropriate usability to support FAB construction management at site. The results indicate that the FABAR is applicable for FAB construction management. Especially, the BIM data transformation method using Room-box in this study signifies a new construction management approach using fluctuating BIM design data in the fast track construction condition.
