Construction equipment is a very important factor for successful construction. Also, the cost for construction equipment is a major part of the cost of construction. Therefore, the estimation of the equipment cost is a critical task in construction planning. A formula for production rates shown in 'Standard Unit Labor' has been used to estimate construction equipment capability and cost. Although the performance of the equipment has improved over time, the variables in the formula have not been updated in a timely manner. Therefore, this paper has analyzed the preceding research, and performed several site visits to measure the cycle time of a backhoe and a loader. Construction equipment production rates were calculated with collected cycle times and variables given in 'Standard Unit Labor'. In addition,production rates were estimated considering the circumstances of various sites with the simulation program 'crystal ball.'

The system to appraise the execution capabilities of construction companies had been began as the Construction Contract Restriction System in 1958, was changed as the Construction Subcontract Restriction System in 1961, and finally has been operated as the Appraisal and Public Announcement of Execution Capacity (APAEC) from 1996. The APAEC system has been utilized as a firm and unique tool for assessing the execution capacities of construction companies despite many problems and continuous system changes. In spite of numerous studies to improve the APAEC system, however, efforts to analyze the system from the empirical point of view were insufficient. In this study, we analyze the status of APAEC system through analyzing correlations among assessment results of the APAEC, earned values of construction works, construction management performance indexes, and macroeconomic indexes for the past 10 years from 2007 to 2016. As a result of the analysis, it was found that Appraisal Value of Execution Capacity (AVEC) is excessively inflated in engineering and landscaping areas compared to Earned Value of Construction Work (EVCW) and the correlations between the AVECs and EVECs are not high in the areas of engineering, industrial equipment, and landscaping. In addition, technical appraisal values are excessively inflated in engineering and landscaping areas and correlations between AVEC and its components are high in the areas of engineering & building, industrial equipment, and large companies, but low in the areas of engineering, building, landscaping, and small and medium companies. Finally, the concentration of the AVEC is intensifying more and more and the concentration deteriorates construction management performance indexes and macroeconomic indexes. If we continuously improve the APAEC system based on the implications derived in this study, the APAEC system will be able to maintain it's position of a firm and unique means to access the execution capacities of construction companies.

To help a owner selecting proper contractors about the specified contract, the Evaluation and Public Announcing System of the Contractor's Construction Capacity has been introduced since 1997. But, the system has been done violence to its original meaning and purpose as time went on. When annually announcing the Contractor's Construction Capacity, especially, there was frequently a large range of opinion on the issues. On that account, MLTM(Ministry of Land, Transport and Maritime Affairs) has had to make a alteration to improve those and is making efforts for a constructive policy now. The purpose of this paper is to conduct a basis study on the Integrated System after reflecting points to be considered about improvements and the current of the times.

Heavy equipment is a very important factor for successful construction implementation. Also, the cost for heavy equipment is a major part of construction cost. Therefore, the estimation of equipment cost is a critical job in the construction planning phase. A formula for production rates shown in 'Standard Unit Labor' has been used to estimate construction equipment capability per hour and cost. Although the performance of equipment has been improved, the efficiency rates in the formula are not updated lately. Therefore, this research performed several site visits to measure construction equipment working time and then calculates the efficiency rates for hydraulic backhoe, loader, and dump truck. The results show that the measured efficiencies of backhoe and loader are higher than current ones and vice versa for dump truck. This research proposes the needs for a standardized calculation formula and systematic and long-term data collection and measurement for updating efficiency rates for heavy equipment.

국내 시공능력평가는 15위이지만 해외고급건축 시공실적 1위로 국내보다 해외에서 그 명성이 높은 쌍용건설이 시공 능력 뿐만 아니라 안전관리분야에서도 새로운 지평을 열어가고 있다. 안전관리로 대한민국 이미지까지 상승시켜주고 있는 쌍용건설은 2009년 대비 2010년 재해율 80%라는 놀라운 감소율을 보이며 올해 건설안전계의 다크호스로 떠오르고 있다. 앞으로 국내에서도 1위 쌍용건설로 급부상하기 위해 가치로 두고 있는 것이 바로 안전관리다. 이들 안전관리를 총 진두지휘하는 사령본부 안전환경부를 찾아 쌍용건설만의 안전관리에 대해 들어보았다.

APEC(아시아 태평양 경제협력기구)의 국가간 기술자 인증 및 UIA(국제 건축가연합)의 건축사 상호인정에 대한 문제가 대학 건축교육의 민감한 이슈로 떠오르고 있다. 건설 경기는 IMF여파의 연속선상민 불황의 늪으로 치닫고 있는 느낌을 떨쳐 버릴 수 없는 위기에 직면해 있다. 더불어 각 건설업체는 기술경쟁우위의 확보, 수주능력 창출, 원가절감을 통한 이윤극대화 등의 요구가 날로 심각해지는 상황에서 건축환경의 변화에 대응할 수 있는 기술자로서의 능력있는 인재를 배출하는 것은 건축교육을 담당하고 있는 입장에서 보면 필수 불가결한 과제가 되었다.(중략)
