In this study, Dr. Bae Kyu-woong of the Korea Institute of Construction Technology developed a concrete module that was lightweighted to 1700kN with KC modules and met housing performance standards. It solves Construction lifts problem that was the limit of the PC module, and is an innovative model that greatly improves Construction period and economics with boxed modules, and is manufactured in the factory by extruded molding in vibration, noise, fireproofing standards, etc., and has the advantage of excellent precision and high strength. Therefore, if the framing house of a precast concretecan only be standardized in construction, its potential for growth will be endless. To do this, standardization, standardization, and modularization of the design are essential.

Unlike new construction projects, road paving maintenance work shows large productivity discrepancies depending on the conditions of the worksite. The current construction cost calculation scheme, however, only provides daily construction volume categorized by work scope and scale: There are no detailed standards that can be implemented on various types of worksites. To develop standards that enable the calculation of appropriate construction costs by taking into account worksite conditions, the current study conducted on-site surveys and interviews. The on-site research and analysis revealed that location, construction width, the day's worksite lot, work scope, and construction objectives were found to cause differences in construction volume. In addition to the existing work scope and work scape variables, the current study added weight constants reflecting the daily work volume based on movement conditions at site and the size of the worksite lot. In this process, the current study found that even one type of construction project can have fifteen different levels of daily construction volume. Such detailed classification was deemed to enable the proper calculation of construction costs based on worksite conditions.

Recent economic slump has highlighted the needs for the construction industry to develop strategies to improve productivity and overhaul organization structure. Notably, it is urgent to improve productivity of apartment building construction projects that account for about half of the aggregate revenue of building construction projects in Korea. As construction site management manpower staffing plan has close relation with the productivity of building construction, it is essential to staff construction sites adequately in consideration of site conditions and characteristics. However, construction companies of Korea are still far from developing site management manpower staffing plan in reference to quantitative standards. Therefore, this research aims to analyze site management manpower staffing plan of apartment building construction project by means of density analysis. To be more specific, site organization charts and staffing plans of apartment building construction projects put together by large construction companies in Korea are studied and essential resources and their mobilization time of apartment building construction projects are examined. Conclusions herein will provide basic inputs to subsequent studies of apartment building construction site management manpower staffing standards.

The maintenance and repair work of sidewalk block pavement is a construction that requires a large amount of budget to be invested every year. It is important to establish an appropriate standards for estimating construction cost to ensure proper budgeting and quality. In this study, the standards for estimating the cost of maintenance and construction work for sidewalk blocks that can be applied to the construction volume classified according to the site conditions, construction type, and equipment use differentiated from new construction was established. As a result, the daily construction volume was presented by reflecting excavator and truck as equipment in the combination of paver and common worker. The re-installation was applied by separating the construction volume of sections with general blocks and induction/raised blocks based on the installation of sidewalk blocks after demolition. Generally if block cutting is necessary, the precision construction conditions using a cutting machine were taken into consideration to secure the construction quality. In addition, it has been revised to apply classified construction volume into A and B-Type depending on the park and site conditions.

After laws for recycling promotion of construction wastes was established on December, 2003, successive technical and institutional measures related to construction wastes are driven. Typically quality standards for recycled aggregate were enacted and officially announced, and recently the quality assurance system for recycled aggregate is promoted to be established. In relation, this study reviewed major factors affecting certification examination necessary to carry out quality assurance system for recycled aggregate and related standards to guarantee the quality of recycled aggregate. More specifically it is suggested that working place examination related to manufacturing facility and planning, quality control manpower and system, environmental and safety control, etc, and quality inspection with classified by for road construction, for concrete, and for asphalt concrete are used as quality assurance standards.

터널공사는 국내 공공건설공사의 중요한 부분을 차지하고 있으며, 다양한 장비와 기술의 개발로 터널공사 시공방법이 발전하였고 현장에 적용되고 있으나 공사비산정기준은 아직까지 현장실태를 제대로 반영하지 못하고 있다. 본 연구에서는 현장실태를 반영한 공사비산정기준 수립을 위하여 관련 문헌조사 및 현장조사를 통해 합리적인 터널공사비 산정기준을 제시하였다. 먼저 현재 건설공사 표준품셈에서 정하는 터널공사비 산정기준의 각 항목들을 분석하고 현장조사를 통한 실제 현장시공의 실태와 비교 분석하였다. 주요 조사내용으로는 암판정 및 내공측량, 천공속도, 버력처리 장비조합 등 싸이클 시간과 관련된 작업 시간에 대한 조사와, 굴착 투입인원에 대한 현장별 적용실태를 확인하였다. 현장 조사결과를 바탕으로 터널굴착 1발파당 싸이클 시간, 천공기계의 천공속도, 버력처리 장비조합, 터널굴착 투입 작업인원에 대한 개선안을 제시하였다. 싸이클 시간의 경우 천공준비 시간에 암판정 및 내공측량 시간을 반영하였으며, 천공기계 속도는 컴퓨터 점보드릴의 천공속도를 반영하였다. 버력처리는 상차장비의 규격을 현장 시공실태에 맞추어 개정하였으며, 터널굴착 투입 작업조를 현장실태에 맞추어 개선안을 제시하였다. 본 연구를 통하여 현장 시공실태를 반영한 공사비산정기준이 제시되었으며, 터널공사 적정공사비 확보에 일조할 것으로 기대된다.

Owing to WTO/TBT, Many countries are trying to accord their own various national codes and standards with international standards. Also Korean electric power code is being made consistent with the new standards which include the international standards. The new code will affect the many aspects of building construction. In order to cope with the change of the electric power code, this paper analyzed the trend of the international standard(IEC 60364, IEC 61024) and we think this study will help engineers to understand the international electrical standards.
