Professional Construction Management (PCM) services have become more and more popular in Taiwan in the past decade. However, disputes between PCM consultant and the client on the performance of PCM services are also increasing. The evaluation of PCM performance is a tough task due to the lack of "physical product", such as the drawings finished by the architect. This paper is intended to propose a PCM performance evaluation system (PPES) based on Balanced Scorecard (BSC). A case study of PCM consultancy for a real world design/build project is conducted to demonstrate the applicability of the proposed BSC framework

Pavement cutting work frequently occurs in new building construction, reconstruction, and complex construction, and this work causes a lot of noise and dust. Eco-friendly pavement cutters are being developed to reduce noise and dust in this work, however the on-site cutting performance of the equipment under development has not been quantified. In this study, the eco-friendly pavement cutter was applied to four residential areas in Seoul and Gyeonggi-do, and its cutting performance was quantified. As a result of the analysis, the eco-friendly pavement cutter showed cutting performance of 20.1~46.9sec/m, and the average was 33.5sec/m. In the future, we plan to conduct additional cutting experiments with various mixing ratios, materials, and depths to confirm the performance of eco-friendly road cutters in more detail.

Corporate Social Responsibility has become a hot issue for modern enterprises recently. Under this trend, companies have to focus on what they can do for society instead of on just making profits. This paper is to explore the relationship between ecological corporate social responsibility and organizational performance in the construction industry in Taiwan. 192 samples were collected from Taiwan's general contractors and analyzed using factor analysis, correlation analysis and path analysis. This study found: (1) in general, the contractors in Taiwan don't devote much to realizing ecological corporate social responsibility, and there is still much room for improvement; (2) the correlation analysis results indicated there are significant positive relationships between ecological corporate social responsibility and organizational performance; and (3) according to the path analysis results, a contractor can improve its business performance by improving its realization of corporate social responsibility.

한정된 예산으로 다수의 건설 사업을 동시에 수행해야 하는 공공토목건설부문에서 건설사업의 수행성과에 대한 관심이 높아지고 있다. 따라서 기획예산처의 자율평가제도, 건설교통부의 사후평가제도와 같이 공공사업 성과 평가제도가 도입되었다. 그러나 국내실정과 상이한 외국의 유사 정책 및 제도를 그대로 도입하는 실정이다. 따라서 본 연구는 공공건설사업의 성공적인 성과평가를 위한 기초 연구의 일환으로 공공건설사업의 성과분야를 결정하고 성과분야 간 중요도를 제시하였다. 이를 위해 건설분야 전문가에게 설문조사를 하여 AHP를 활용하여 가중치를 결정하였다. 그 결과 건설전문가들이 직관적으로 생각하고 있는 건설성과의 중요도와 AHP 결과 도출된 중요도가 상이함을 알 수 있었다. 또한 건설주체별(발주사, 시공사, 감리사, 설계사)로 건설성과의 중요도를 비교하였다. 이를 통해 각 주체들이 건설사업의 성공적인 수행이라는 하나의 목표로 각자 노력을 기울이고 있지만, 중요시하는 성과분야는 상이함을 알 수 있었다. 이러한 문제를 사전에 예방하기 위해서는 공공사업 초기단계부터 공동의 노력이 필요할 것으로 사료된다.

A major performance stage carpenter, Jang Insang led performance stages from the 1719 Sukjong Royal Banquet and was confirmed by historical records to be the first craftsman. Lee Wandeuk led the Hwaseong Fortress performance stages of the Jeongjo period and Gichuk Jinchan performance stages of the Sunjo period. The carpenter techniques he used during the Jeongjo period were succeeded to the Sunjo period. Ahn Sungil was the head craftsman who led the performance stages of Jagyeongjeon Jinjak, Muja Jinjak, and Gichuk Jinchan of the Sujo period, under which the foundation for court palace performances was laid. The progression of major carpenters includes Jang Insang of the Sukjong period, Jeon Yoochu of the Yeongjo period, Ahn Sugil of the Sunjo period, Yoon Seoksin of the Heonjong period, Kim Yoonsik of the Gojong period, Lee Jongyoon, Kim Soongil, Seo Sangmook, and Han Sujoon. In addition, the Major Repair of Injeongjeon Hall (1857) of the Cheoljong period was the most important palace construction project for transferring the carpenters' skills. Through this project, Ahn Sungil of the Sunjo period, Kim Myeonggap, Yoon Seoksin of the Heonjong period, Kwon Deuknyang, and Kim Sungil of the Gojong period were able to interact with each other. That is, this major repair project of Injeongjeon Hall reflected the major carpenters' best techniques through performance stage construction, showing the progression of Ahn Sungil, Yoon Seokshin, and Kim Sungil, who led the constructions of Gichuk Jinchan of the Sunjo period (1829), Mushin Jinchan of the Heonjong period (1848), and Jeonghae Jinchan of the Gojong period (1887), the most impressive performance stages of the late Joseon period. The carpenters of the court performance stages participated in important construction projects of the royal palace, reflecting the superior technical skills of the carpenters in the construction of court palace performance stages. The carpenters who played a leading role in the construction of performance stages were able to interact with one another and transfer their excellent technical skills, providing the driving force that allowed court performance stages to blossom into splendid and high-quality court stages in the late Joseon Dynasty.

Energy load of building affected by insulation performance of building's exterior. and insulation system can be classify interior insulation, exterior insulation, sandwich insulation according to install place of insulation. but within interior insulation system, corner wall and the cross outer wall-slab insulation part may occur thermal bridges. And then, within exterior insulation system is more superior insulation performance than interior insulation, but it has difficult to apply, easily broken at high building because of strong wind load. And also difficult to maintenance exterior insulation system. So, in this study, to found requirement performance of cast-in-place sandwich insulation system that is superior insulation performance and easy construction and maintenance. requirement performance of cast-in-place sandwich insulation system is 1) To avoid thermal bridges in the insulation performance, 2) Both sides concrete wall can be composite action in the structural performance. Because of this study, can develops cast-in-place sandwich insulation system and this insulation system contribute to improve insulation performance of apartment-house and high building.

As the Long-life certification system is recently introduced in the Housing Law in Korea, it is expected that an application of the lightweight wall panel will be increased in apartment construction as the main wall system. However, the performance criteria for lightweight wall is in the early phase of its action. Therefore, it is necessary to establish the performance criteria properly by investigating performance requirement in the user's perspective. The purpose of this study is to identify of the weight of the required performance items for the lightweight wall in apartment house. To analyze the priority in the performance, an interview survey is performed; after monitering the test-bed of the lightweight walls, user and experts evaluate the performance requirements. The weight of the performance requirement is developed by AHP method.

The development and utilization performance of the construction new technology was introduced in 2014 according to the detailed evaluation criteria of the construction project of Ministry of Land, Infrastructure and Transport. In the case of the construction new technology, the current standard is give 3 points in the "technology development and investment performance" evaluation item. However, construction engineering companies is difficult for to invest the capital required for new technology development. Therefore, in this study, we try to extract the difficult factor that occur in the process of construction new technology development in terms of construction engineering companies. The research results are expected to provide with the support policy guideline for new technology development costs to policy makers.

This present paper mainly contains adhesion part disconnection type exposure composition waterproof method using embossing PVC sheet. The existing polymer resin coating and sheet waterproofing construction method have, however, some weak point such as being decrease life cycle of concrete with water leaking from materials be affected by crack and movement dash bond concrete through the whole-adhere construction. Above the reason, this paper has particular method increasing crack-defending performance from stress occurred concrete movement by part disconnection, adds maintain waterproofing performance subordinate sheet, that can be contributed a convenience of maintenance which is decreasing industrial waste and repair construction cycle through the part repair in case of leaking water.
