As the construction technology is rapidly advancing internationally, the necessity of virtual construction technology development is drastically demanded in the construction industry together with a fusion technology with information technology(IT). The construction technology will be changed as the paradigm of construction technology in the future. The establishment of building structural system in the virtual construction basis is necessary for the integration of construction process, and it will be expected to produce the effect of reduction of construction period and quality improvement through the environment of integration. This study is to present the analysis of the existing process of structural design, the content of research & development as per the building structural system on virtual construction basis and the direction of research.

The planning process for roadway construction involves a large amount of information on design, construction methods, quantities, unit costs, production rates, and site conditions. Therefore, it is very important to acquire, manage, and process the necessary information efficiently to produce a rigorous construction plan. GIS (Geographic Information System) is a very effective tool for integrating and managing various types of information including spatial and non-spatial data required for roadway construction planning. This paper proposes a GIS-based system for improving roadway construction planning with its 'Interactive Space Scheduling' and 'Operation Level Planning' functions. The proposed system can assist construction planners in a unique way by integrating design and construction information and creating modularized design elements for space scheduling in real time. It is expected that the proposed system could improve the efficiency of roadway construction planning.

As one of the most important vertical transportation equipment in super high-rise buildings, the construction elevator directly affects the project period, cost, and effectiveness. The paper proposes a new construction elevator with single-guide rail and multi-cages. It can solve the problems of single construction elevator capacity shortage and efficacy decrease with height reduction, the occupancy of plan and elevation position of multiple construction elevators, and extension of total construction period by cycling operation of multi-cages on a single-guide rail. The paper focuses on the design and research of the main components of the equipment, such as the rotating guide rail mechanism, vertical bearing mast tie system, segmented electrical power supply system, group control scheduling system, and safety anti-collision system.

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.

A large-scale research project to develop a robot-based automated building construction system for steel structures was successfully conducted in South Korea. This paper discusses the results of the real-scale test and the key lessons gained from the testing process. The system was assessed in terms of system productivity, construction cost, quality control, and safety improvements. While the productivity of the automated system showed an improvement of about 9.5%, the construction cost was about six times higher than that of the conventional method. The field test also indicated that the automated system requires more on-site quality control measures. However, because the system can eliminate the causes of various safety accidents, safety levels might be expected to be improved significantly. It is expected that this paper will provide knowledge and insight for developing new systems, and the results of the real-scale test might be useful for other researchers and similar research projects in the future.

건설사업 VE는 크게 설계단계 VE와 시공단계 VE로 분류되며, 적용 시기가 빠를수록 그 효과가 향상된다. 이에 따라 설계단계 VE가 2000년에 법제화되어 활발하게 적용되고 있다. 하지만 설계 VE 제도와 상호보완적일 수 있는 시공 VE의 활성화가 절실하다. 그동안 시공 VE 제도의 필요성, 기술개발보상제도의 개선, 시공 VE의 구체적인 실천방안 등을 제시하여 시공 VE의 활성화를 위해 많이 노력하였지만, 관련 법 규정의 미비로 인하여 효과적이지 못하였다. 본 연구는 이러한 국내 현실을 인식하고 시공 VE의 활성화를 위해 국내외 시공 VE 제도를 비교 및 분석하고, 건설산업 각 분야 전문가 설문조사를 실시하여 국내 건설산업에 적합한 시공 VE 제도의 개선방안을 제안하였다.

최근 건설 프로젝트는 대형화${\cdot}$복잡화${\cdot}$고도화 되어 가고 있다. 이에 따라 비용${\cdot}$기능${\cdot}$품질을 최적화하기 위한 VE의 필요성이 강조되고 있다. 하지만 VE는 건설 분야에서 적용과정이나 방법상의 어려움으로 활성화 되지 못하고 있다. 건설 분야에서 VE를 활성화하기 위한 대안 중 하나는 인센티브제도를 도입하는 것이다. 인센티브 제도를 통해 발주자는 해당 프로젝트의 원가절감을 할 수 있고 시공자는 이윤 창출을 극대화 할 수 있을 것이다. 국내의 경우 지난 1992년 미국의 시공 VE 인센티브 제도와 유사한 '기술개발보상제도'를 마련하여 시공자의 기술개발노력에 대한 제도적 지원책을 제시하였으나 그 실적은 매우 저조하였다. 본 연구는 국내${\cdot}$외 건설VE 인센티브 제도를 고찰하고 건설VE 전문가를 대상으로 설문조사를 실시하여 국내 건설VE 인센티브 유사제도의 문제점인 '건설VE 인센티브 조항 및 기준의 미흡', '건설VE 평가자 및 전담부서 미흡' 등을 도출하였다. 도출된 문제점을 바탕으로 건설VE 전문가와 면담을 실시하여 건설 산업에 건설VE 인센티브제도를 도입하기 위한 방안으로 '건설VE 인센티브제도에 관련 법 및 제도의 개선', '건설VE 전문가 및 조직구축' 등을 제시하였다.

The productivity is the one of the primary elements to evaluate the new systems performance for building construction along with the economic efficiency, the safety, and the quality improvement. At present the on-site construction automation systems(we will call it as Construction Factory or CF hereafter) is under the development by research group for construction automation of high-rise building. The system includes many sub-systems such as a robotic crane, a construction factory, bolting robots, a building material management system using RFID and so on. In this study we discuss and propose the method to evaluate for these hybrid on-site automation system fundamentally. In future we devise a framework of evaluation modules for the on-site building automation system on the basis of this discuss.
