Planning and Scheduling in Korean has been developed from Bar Chart to CPM, integrated management and EVM were attempted. As growing of overseas projects, Scheduler was also recognized as important one. However, the reality is that most Korean construction projects still remain in the preparation of construction plan and construction schedule in 1990s. The global Planning and Scheduling trend is EOT claims. I would like to understand the global trend of EOT claims and EOT analysis, and to find out Planning and Scheduling measures to successfully promote EOT claims.

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 projects have high potentials of claims among a variety of stakeholders. Claims on their own are not disputes but they have high potentials leading to disputes if agreements are not made between parties due to conflicting opinions. In the event of the construction disputes between clients and contractors, it could give negative impacts to both parties and, to minimize or pro-actively manage construction disputes, the role of clients is more significant. The objective of the study is to analyze a level of associations between the types of disputes and causes of construction projects based on the association rule analysis, and to identify and discuss key characteristics and implications from client's perspectives. The study analyzes associations between the types of disputes and causes, and also identifies those with a high level of associations. It also presents the outcomes of more systematic analysis compared to descriptive statistics just based on frequencies. Through the analysis of the data cases, the study proposes the directions to resolve the causes of disputes from client's perspectives. It can assist to improve understandings of the relationships between the types of disputes and causes and to pro-actively manage the disputes of construction projects.

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.

The construction industry has more safety accidents than other industries. Although there have been more attempts to reduce safety hazards in the industry such as the enforcement of the "Serious Accidents Punishment Act (SAPA)", construction accident has not been reduced enough. In this study, analysis of safety risk factors has been made through Latent Dirichlet Allocation (LDA)-based topic modeling. Risk analysis in construction site would be improved with natural language processing and topic modeling.

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.

Since the cases of time extension have continuously transpired in the public construction project, the potential of economical loss and claims is increasing because the concerned parties such as an owner or a contractor have not properly performed their own responsibility for time extension. One of the main reasons is that the present planning and scheduling do not support the method to apportion the proper responsibility to the right party. This problem has repeatedly led to time extension and made it difficult for the concerned parties to perform the responsibility for time extension. In order to overcome this problem, a framework of delay administration is required as the method to apportion the proper responsibility to the right party. To solve this problem, this paper aimed to develop the conceptual model and prototype system as the practical method to administrate delay causation. Furthermore, the verification result for the reliability and applicability throughout the case studies on real construction projects shows that the conceptual model and prototype system developed would help efficiently to administrate the delay causation.

The BTL and CM are main issues in Korea construction industry lately. The BTL applying CM is sufficient to have interest in terms of combination of BTL and CM. OO Cultural and Welfare Complex Town construction was the first cultural and welfare facility with the BTL applying CM. Because application of CM to the BTL project is at the early stage, there are many problems under the progress such as administration procedure from misunderstanding of the BTL and lack of communication between supporting Dept. and management Dept. This article focuses on those problems and advantages of CM services including negotiation, schedule management and cost management for the better CM service in the BTL project in the future.
