Most of the construction works in domestic are not direct undertaking work, but by a contract method including subcontracting. Therefore, a general contractor for each project jointly carry out construction work with a specialty contractor for each engineering type. However, in terms of contract, this method is not a joint venture contract, but a subcontract. Accordingly, this system can cause various problems between the prime contractor and the subcontractor. Therefore, this study aims to extract and present the actual obstacle factors in terms of specialty contract company performing specialty construction work for construction project. The presented contents are expected to present the standard for the cooperation system that the prime contractor and the subcontractor can win-win.

In this paper, we conducted a study to understand the impacts of safety behavior, safety and health delivery and communication, which should be managed for the establishments' safety and health control on occupational safety and health policy satisfaction to utilize that as a material for preparing policy support and preventive measures. For this purpose, we conducted a statistic analysis with 2,970 establishments, utilizing the material, "2015 Occupational Safety and Health Company Survey". As a result, in the manufacturing industry, it turned out in the establishments with more than 300 workers, safety behavior, safety and health delivery and communication of the cooperative firm of the prime contractor were high. In addition, it turned out that safety behaviors had the biggest impact on occupational safety and health policy satisfaction in the manufacturing industry and safety and health delivery and communication had the biggest impact on occupational safety and health policy satisfaction in the construction industry and other industries. As for the relationship between companies, it turned out that safety behaviors had the biggest impact on that between the parent company and a cooperative firm of a prime contractor while safety and health delivery and communication on that between the prime contractor and the subcontractor. Through the results of this study, it is necessary to build up safety and health behavior and safety and health delivery and communication systems for the characteristics of the company, and it is expected that the effect of the safety and health control will increase when policy support is made accordingly.

턴키공사는 설계를 도급자가 하기 때문에 설계오류로 인한 공사금액의 증액은 없다. 따라서 설계오류로 인한 공사비의 증가는 도급자의 원가율을 상승시키는 결과를 초래하고 그로인한 도급자의 채산성은 감소할 수 밖에 없는 실정이다. 또한 설계오류는 설계변경의 기간만큼 공정을 지연시키고 오류를 인식하지 못하는 경우 심각한 품질문제를 야기 시킬 수 있다. 본 연구에서는 턴키공사의 설계오류 원인을 조사하여 설계오류를 감소시킬 수 있는 방안을 제시함으로써 설계오류로 인한 원가율 상승과 공정지연, 품질저하의 문제점을 해소하고자 한다.

Objectives: The purpose of this study is to review the debate on the Article 28(Prohibition of Inhouse-Contract for Harmful Work) of the Industrial Safety and Health Law. Methods: Literatures and recent debate for prohibition and permission of inhouse-contract for harmful work were reviewed. Proposals of revision for the Article 28 of the Industrial Safety and Health Law were also reviewed. Results: It was not found reasonable to revise the Article 28 based on increased fatal accidents or diseases in the electroplating work and heavy metals handling works that are currently listed in the Presidential Decree under the law as the harmful works. Regulation types of prohibition or authorization for any harmful work shall have inherently poor coverage since the scope of application is extremely limited. Contractors for maintenance and repair of chemical facilities may not be included in the scope of application if the harmful works are defined as chemical handling works. If harmful works are prohibited, the contractor workers may loose their jobs. Therefore, it is necessary to consider balancing job security and occupational safety and health safety. Conclusions: Various limitations were found in the Article 28 and the proposals to revise it. Currently in-house subcontracting is widely spread in the workplace. Therefore, it may be inappropriate to set one or two Article such as the Article 28 and 29 to protect in-house subcontract workers from injury and illness. It is believed that it needs fundamental redirection and new approach with new paradigm to impose occupational safety and health duty to prime contractors.

Various construction bonds and warranties critically burden the general contractor. Also, sporadic or cumulative delays of progress payment by the owner can further trap the contractor in a financial quagmire. Facing the possibility of cash flow deficiency and callous response from the banks, most construction firms may become financially incapable of market competition, and attractive project tenders become a bidding game among few deep-pocket players. The downside of such market environment is that the depth of pocket, rather than that of professional competency dictates the choice of market winners. In Taiwan, this has been a potential crisis to the construction industry after the financial crisis which started out since 2008. To encounter this problem, this research will examine the means to better manage the construction industry. Essentially, a credit guarantee system (CGS) is the prime solution to strengthen a bank's confidence in any particular construction firm. Thus establishing a national platform which evaluates and rewards a construction firm's overall credibility is pivotal, and this third-party rated credit can help a bank to render a loan more wisely. Finally, this paper will propose the ideal operating schemes of construction-specific CGS in Taiwan and a credit scoring prototype model for construction industry, as reference for the government and banks, respectively.

건설공사의 주요한 목적은 정해진 공정에 맞춰 공사가 완료되고 발주자가 공사에 대해 만족하는 것이다. 이러한 공사목적의 달성은 전적으로 시공사의 근무태도에 의존한다. 태도는 직접적으로 측정하기가 매우 어려워서, 관측 가능한 여러 지표들을 통해 추측해내야만 한다. 흔히 개인이나 기관에 의해 보여 지는 행동은 대상이나 사람, 주요 요점에 대한 태도를 대변한다. 본 논문의 목적은 진행 중인 건설공사에서 시공자의 태도를 측정하기 위한 체계(framework)를 개발하는 것이다. 본 논문에서 주요태도지표(KAI)는 현장조사를 통해 객관적이고 주관적으로 측정되었다. 제안된 KAI의 유효성은 역시 4가지 사례분석을 통해 확인되었다. 본 논문에 제시된 KAI는 시공사의 태도를 합리적으로 평가할 수 있고, 발주자와 프로젝트 매니저들이 건설공사를 효과적으로 관리할 수 있는데 도움을 줄 수 있을 것으로 판단된다. 본 논문은 차후 연구를 진행하는데 있어 일반적이고 포괄적인 기초자료로써 많은 도움을 줄 수 있으리라 사료된다.

Cost estimate system Will be changed from the prime. cost calculation to the historical cost data because the present system has some problems. In this situation, each owner should prepare his own cost estimate system based on the historical cost data. In this study, the standard work items were classified and the criteria of their work amount computation were established for rural improvement projects. And also the historical cost data were collected in all range of rural improvement projects, and the database system, "HICOMS" (HIstorical COst data Management System) was built. In order to test the applicability of the HICOMS, standard work cost and contractor cost were compared. The results by HICOMS showed high significance and it was concluded that the HICOMS could be applicable for the cost estimate of the rural improvement projects. projects.

공공건설사업에서 많은 건설회사들은 하도급으로 공사를 시행하고 있다. 하도급은 건설현장에서 빠질 수 없는 현실이고, 국가에서는 법령을 만들어 하도급인을 보호하고 있다. 하도급거래 공정화에 관한 법률에서 수급인의 부당한 하도급대가 지급금지, 선급금지급, 하도급대가의 직접지급 등을 규정하여 하도급인을 보호하고 있다. 이러한 하도급인 보호규정중에서 하 도급대가의 직접지급은 하도급인을 두텁게 보호한다는 취지도 있다. 그러나 한편으로는 이러한 규정으로 인해 수급인이 부담하고 있는 하자담보책임과의 연계성부분에서 클레임이나 분쟁이 발생할 가능성이 있다. 따라서 본 연구에서는 하도급대가의 직접지급과 관련한 실정법규나 제도의 내용을 살펴본 후 하도급대가 직접지급으로 인한 계약적 효과를 고찰한 후 예상되는 문제점을 최소화할 수 있는 방안을 모색하고자 한다. 본 연구 결과 하도급대가 직접지급과 관련된 문제를 최소화하기 위한 방안을 요약하면 다음과 같다. (1) 도급인에 대한 하도급인의 지위를 분명히 규정해야 한다. (2) 하도급대가 직접지급시 하도급계약서 및 계약이행보증이 도급인과 수급인의 계약관계를 보완하는 것으로 규정해야 한다. (3) 하도급대가 직접지급시 수급인 및 하수급인의 목적물에 대한 하자담보책임을 분명히 하기 위해 일정금액을 유보할 필요성이 있다.

최근 모듈러 건축물 관련 연구가 활발하게 진행되고 있으나, 실제 건설산업에서 모듈러 건축물을 활용한 건축공사의 발주는 아직 활성화되지 못하고 있다. 이에 대한 여러 가지 원인들이 분석되고 있으나 그 중 중요한 것은 모듈러 건축물은 기존 현장중심의 건설생산체계를 공장제작-운송-현장설치 새로운 체계로의 전환을 요구하고 있다는 것이다. 하지만 국내 공공공사의 기존 발주방식은 전기통신공사업 등 개별법에서 분리발주를 의무화하고 있기 때문에 모듈러 건축물 장점을 살릴 수 있는 새로운 건설생산체계를 수용하기 어렵다. 따라서 기존 발주방식은 모듈러 건축물을 현장중심의 공사로 분리발주(건축 토목, 전기, 통신, 소방 등) 계약할 수밖에 없고, 건축 토목공사의 계약 범위 안에서 모듈러 유닛을 물품으로 구매할 수밖에 없기 때문에 이러한 분리발주로 인한 모듈러 건축물의 공장제작 비율을 저하시키고 공사비 상승, 품질저하 등의 문제를 발생시켜서 모듈러 건축물의 장점을 발휘하지 못하도록 하는 장애요인이 된다. 본 논문에서는 모듈러 건축물에서 요구하는 새로운 건설생산체계를 적극적으로 수용할 수 있는 새로운 발주방식을 개발하여 제안하고자 한다.
