Claims in the construction industry can have a serious impact on the profitability of the project or can even result in project failure if it fails to take appropriate prevention. In order to properly prevent and respond to the potential claims and legal disputes throughout the project execution, it is necessary to continuously accumulate informations and clearly define the roles and responsibilities of the important activities systematically. Based on these needs, this study develops and verifies the project information management system(PMIS) that can prevent and respond possible claims for construction projects. Developed system includes such management modules as schedule, cost, PM/CM, design, collaboration, and claims. The system was validated by adopting it to the practical projects. The results showed that information systems tailored to the construction claim need to elevate users' familiarity to be more useful. Besides, the system can be more functional when used by both owners and contractors.

Many studies on cause and prevention of claim have been carried out but they were mostly intended to come up with the improvement measures, improvement system or the measures to deal with the claim, which consequently lacked the substantial ways to identify the details of claim for prevention purpose. That is, there's in fact no tool, in preparation for potential claims, to identify and review the major potential causes at design stage to mitigate the claim and thus, it's necessary to develop the tool such as checklist needed to prepare the claim-supporting documents, check the relevant laws as well as to identify the cause of claim. Hence the study, given the fact that cause of claim is mostly generated at the design stage though the claim itself tends to occur at the construction stage, was aimed at developing the checklist based on contract document such as design documents at design stage for public construction projects in a bid to prevent the potential claim occurred at the design stage.

As the prefecture railroad construction accelerates, unmanned system's reliability and safety is increasing in demand. Accordingly, effective management of construction projects for the PM and SE techniques are being applied, with the introduction and use of PMIS computerized systems. Due to the construction of railways, from the start of PMIS research planning, design, procurement, to construction and commissioning, various expertise is being carefully gathered, and by integrating it into the unified budget ideas and processes, rational, efficient, organized, and manageable financial plans are developed for the computerized system. However, the current PMIS does not take into account the life-cycle. This study is to bring attention to the BIM smart BOM-based configuration management for life-cycle through the consideration for railway construction project management.

Purpose: The purpose of this study is to analyze the Safety and Logistical Distribution Management system in Thailand's Highway Work Zone based on data from Logistics drivers. Accidents in highway construction zones have caused enormous casualties in Thailand yearly. Statistical data shows evidence of correlation between numbers of accidents and drivers' recklessness. Research design, data, and methodology: In this study, we conducted an in- depth interview with 414 logistics drivers and highway construction workers in Khon Kaen province, Thailand. The data was collected based on 63 questionnaires aiming at capturing factors contributing to the risk of safety and cause of accidents in logistic infrastructures such as Highway work zone. Results: The result reveals two significant factors affecting safety in highway work zone, which includes construction environment and safety management system. Moreover, the result shows that feeling of afraid and confused while driving within the construction zones significantly affecting driver's risk of having an accident. Conclusions: The findings of this study offer that a strategic planning and evaluation of the logistics drivers' satisfaction and construction workers' participation to mitigate highway accidents at construction zones and that drivers' knowledge and perception toward construction safety management plays a significant role in preventing highway accidents at the construction areas.

Construction business VE is classified into design stage VE and construction stage VE. The faster the application, the better the effect. Therefore, the design stage VE was legislated in 2000 and actively applied. However, it is urgent to activate the construction VE, which is complementary to the design VE system. In the meantime, we have made a lot of efforts to activate construction VE by suggesting the necessity of construction VE system, improvement of technology development compensation system, concrete implementation method of construction VE, but it was not effective due to lack of related laws. This study compares and analyzes construction VE system in Korea and abroad for the activation of construction VE after recognizing such domestic reality. A survey of experts in each field of the construction industry was conducted and suggestions for improvement of construction VE system suitable for domestic construction industry were suggested.

Automation in construction has been restricted to special classes of tasks. Curtain walls can be handled like standard construction materials; they are heavy but breakable, and are large but require precise installation. These characteristics make the installation of curtain walls ideal for robotic automation. There are two methods for developing construction robots: The first is approving the robot performance and applying it to the current construction methods. The second is admitting the limitation of the current robot technology and trying to optimize the current method of construction to apply the robot system. In this study, we derived the performance requirements of a curtain wall-installation robot. We also tested this robot at a real construction site and evaluated its performance. Finally, the results were analyzed, and we proposed additional research.

Today the social concern about Interior Design gradually requires wide comprehension. Also according to demanders' requirement. Colleges cope with speed. Interior Design made by experts for the function and purpose in the conception of decoration. Therefore, Colleges are responsible to educate for more capable professional designers. But management is the first concern for Interior Design Company students are going to work at. Interior Design has not the important state yet in Korea, it is hard to manage the company with only design works on the table. As architectural design side must get some admission, design is apart from construction. but they are worked together in Interior Design. Also, as the architectural design with process detail drawings, interior design is required the detail design for construction. But it is the facts that the college is interested in and concentrated on rather education for design and space plan than intensive education for construction because of the restricted environment of practice room. I propose component and practical use of nude construction department to understand detailed design.

Modular construction has benefits such as short construction duration and high productivity owing to the production in factory and owing to simultaneous on-site work. However, rework occurs in modular construction and the rework affects the efficiency of modular construction. The almost of causes of rework are exist in design process. To reduce the cause of rework, the information flow of the design process should be managed and the plan to reduce rework should be included. However, the modular construction has complex process because of impeded unit production so it is hard to manage the information flow in design process. Moreover, when the plan to reduce rework is included, the design process will be more complicated. Therefore, the objective of this research is to suggest the design process including the rework reduction plan and to alleviate the complexity of design process by using Dependency Structure Matrix(DSM). By using DSM, the iteration and feedback in design process is reduced and it can be expected that rework in modular project can be reduced by using suggested design process.

Although issuing change orders is a common practice in the construction phase of any project, non-structural utility subcontractors are struggling and seek to find a way to reduce change orders. Therefore, this paper presents the analysis results on change orders to cultivate possible suggestions and solutions on how to reduce or minimize change orders in mechanical, electrical, and plumbing (MEP) works. Change orders in non-structural utility works are analyzed based on six categories such as rerouting and change of location, changes in weight, rejected design by Office of Statewide Health Planning and Development, District Structural Engineer, or the Structural Engineer of Record, unforeseen conditions, changed equipment, and owner-initiated change. The analysis findings showed that rerouting and changing location is the most significant cause, followed by unforeseen conditions. The results not only contribute to the existing body of knowledge on change order research area, but also help MEP contractors reduce the time and cost of change orders.
