Additional costs as well as schedule delay are occurred due to change orders in today's construction projects. Additional costs, overhead calculation methods are of various types. In a foreign country cases, many claims related to the loss of labor productivity quote research statistics data. In domestic cases, the study of the reason why the loss of labor productivity occurs and its effect have not been performed. Therefore, this paper analyzes factors affecting lost productivity and a methodology is presented to estimate the lost productivity.

Construction projects are based on the actual field, so if the construction schedule that is established in the construction plan is delayed or extended for various reasons, construction companies are vulnerable to claims, and thus strive to complete a building within the planned timeline by shortening the construction time. Therefore, this study surveyed technicians in apartment construction in Gwangju, and studied their perceptions of the actual conditions of process control, construction time needs, goals, and methods. The results showed that the organization of the process control department and professional employees was lacking compared to other regions. The need for construction time was perceived as high, while the reduction of the construction cost was perceived as low. Regarding the reduction goal, they perceived highly the preparation for the delay of construction time and various claims, and for the reduction method, they mentioned the extension of working hours and the increase in employees. Based on the results of this study, technicians should consider that a reduction of construction time not only can make up for a delay in construction, but is also closely related to improvements in production through reduction of cost, and increased international competitiveness.

중국의 한 옛날 이야기 중에 어떤 아버지가 자식들에게 막대기를 건네주고 그것을 꺾어보라고 하자, 아들들은 쉽게 막대기를 꺾었다 는 얘기가 있다. 하지만 이어서 그 아버지가 막대기를 다발로 묶어 서 아들들에게 꺾어보라고 하자, 아무도 꺾지 못했다고 한다. 이 이야기는 사람은 무리를 지어서 함께 일할 때 더욱 강하다는 것을 예시한다. 이러한 이야기는 연결되지 않은 몇몇 콘텐츠 저장소 에 따로 존재하는 것보다, 콘텐츠가 한데 모여있을 때 훨씬 유용하 다는 것을 기술하는데도 적용할 수 있다. 시장조사기관인 가트너그룹(코네티컷 스탬퍼드 소재)은 전형적인 미국 기업이 서로 연계되지 않는 35개의 콘텐츠 저장소(예를 들 어 마케팅 웹사이트, 문서 관리 시스템, 클레임 프로세싱 시스템)를 구축했다고 밝혔다.

2002년 7월 1일부터 시행되는 제조물 책임법은 기업에 많은 영향을 끼칠 것으로 예상된다. 대외적으로는 소비자들의 클레임이나 분쟁, 혹은 소송에 대한 대응이 불가피할 것이며, 대내적으로는 제조공정의 품질 및 문서관리의 강화 요구에 대응하지 않으면 안될 것이다. 결과적으로 결함이 있는 제품의 출하 및 판매는 자칫 기업의 존폐 자체를 위협할 수 있기 때문에, 기업은 제품의 안전성을 평가하는 데 배전의 노력을 기울이고 있다.(중략)

When we consider the present state of construction delay claim analysis, the delay analysis methods generally used from the abroad construction industries are not applied to our industry. By reviewing the existing methods of delay analysis, this study investigated the important concepts and characteristics of the delay analysis methods. Selection of the delay analysis methods could be decided among 1)As-planned versus as-built comparison method,2)What-if method,3)But-for method.4)CPA method, and 5)DAMUDS method. In order to make clear the characteristics and mechanisms of the analysis methods, this study performed a case study.

The purposes of this study are to survey unfair aspects of specific provisions in the construction contract, and to suggest counterplans and institutional reformations. The research method of this study includes judicial precedent analysis and a questionnaire survey, The results of this study are as follows: 1) the main problems of unfair specific provisions are payment condition, shifting of the responsibility and adjustment in the contract sum. 2) counterplans ate suggested according to the construction phase : bid, construction and completion phase. 3) institutional reformations include firming up regulations, supervision, invigoration of claim, development of variation guideline, and so on.

It's hard to express a lot of information within the drawings and the specifications as construction projects have gradually become large-size and complex. So, disputes are caused by that and reason that the usual practice(culture) of contract of the constructions in Korea is based on unfair rather than the fair principle between clients and contractors. However, the contractors don't try to solve this kind of things because they are worried about at their disadvantage situation. Therefore, this paper deduced the factors in the pre-dispute phase by analysing the cases of the civic counseling in the office of supply and the pre-dispute factors, and conduct analysis on the factors' importance by using AHP. The results will be used for a check-list to prevent the disputes.

Construction delays are a common occurrence of most construction projects and difficult to analyze. there are some techniques to analyze delays, such as using CPM, Bar Chart but they are not enough to analyze concurrent and productivity lost delays. Productivity lost delays are different to interruption delays in computing the number of delays and analyzing concurrent delay. This paper describes the delay analysis method considering productivity including concurrent delay analysis.

Cases of the time extension have continuously transpired in the public construction projects. The potential of economical loss and claims is increased because the concerned parties such as an owner or a contractor have not properly performed their own responsibility for the time extension. Therefore, this paper aimed to improvement of apportioning responsibility for the time extension in construction projects.
