For the sustainable development of the domestic construction project management field, each CM company should try to diversify in terms of service contract types and scope of work while having internationally competitive technical and service capabilities as follows. First, from the initiation of the service to the completion, the CMr should be able to establish and execute a plan to create specific outcomes. Second, CMr must have the capability to produce weekly or monthly cost, schedule, risk, and scope management reports. In addition, it should be possible to apply the cost plus sliding fee method or to systematically and continuously accumulate and process data generated during the construction process.

This research explored methods for improvements to be made within the field of drone usage within the construction industry based on an investigation of factors which limit their efficiency and productivity. Limiting factors and improvement measures were presented in terms of technology, service, law and policy for employing drones at construction sites. Our first suggestion is, from a technical point of view, that companies need to expand professional manpower and infrastructure for systematic management. Second, in terms of service expansion, it is necessary to have management capabilities for operation such as the use of drones with enhanced safety and reinforced on-site education and personal information management. Third, in terms of legal and institutional support measures, it is necessary to prepare a plan for reforming the legal system for revitalization and to expand the training of professional manpower. This study may contribute not only to the development of drone technology, but also to effectively respond to various problems that appear at construction sites.

The quality of performance evaluation on engineering consultants that provide design-related technical services is difficult to be measured, and only a handful of papers discussed the quality during the design stage. Although design cost is relatively far less than construction cost for a project, the decisions made in the design phase have a significant impact on the final products of the project, especially for large public construction projects. Therefore, this research focuses on reviewing and then establishing a performance evaluation framework for the consulting firms that execute detailed design and provide technical services for the Taipei Rapid Transit Systems (TRTS). By interviewing experts, this study first established a set of indicators to evaluate these firms' performance. Then, those indicators were incorporated into the four aspects of balanced scorecard (BSC) to establish the architecture of the evaluation mechanism. The weight of each indicator was calculated by analytic hierarchy process (AHP) from a survey conducted among experts. The results showed that the top-three indicators were quantity take-off, functions conformity, and budgeting. The framework of performance evaluation established by this study can be applied to measure service performance during the design stage. It not only facilitates the monitoring of consulting firms, but also helps to reduce unnecessary change orders and disputes during the construction stage.

본 논문에서는 기존 네트워크에서 QoS(Quality of Services) 및 QoE(Quality of Experience)기법들을 분석하고, 재해정보 확산을 위해 끊김없는 N-Screen 서비스들을 제공할 수 있는 고신뢰성 네트워크 시스템 프레임워크 및 그 서비스 전달 기법을 제안한다. N-Screen 서비스에서 콘텐츠 소비자의 만족도, 즉 QoE 는 재해정보 확산에서 중요한 요소가 되고 있으며, 기존 N-Screen 서비스들이 다양한 디바이스들에 정보를 전송하기 위한 기능에 초점을 맞추고 있기 때문이다. 이러한 서비스에 맞춰, 제안된 시스템은 사용자의 서비스 요청을 수용하기 위한 재해정보처리 프레임워크, Push 서비스를 수용할 때 발생하는 패킷의 수를 최소화하기 위한 Push 서비스 모듈, QoE 지표를 최대화 할 수 있는 Push 서비스 컨트롤러로 구성되어 진다. 다양한 스크린(스마트폰, PC, 전광판)에서 끊김없는 N-Screen 서비스를 제공하기 위해 Open API(Application Programming Interfaces) 인터페이스 기능을 가진다. 본 연구의 결과를 통해서 사용자들에게 끊김없는 N-Screen 서비스를 제공하고, Push 컨트롤러 기능 및 효과적인 네트워크 서비스 기능을 제공함으로써 사용자에게 서비스 품질 만족도를 높일 수 있을 것으로 기대된다.

Recently BIM technology has been expanded for using in construction project. However its spread has been delayed than the initial expectations, due to the high-cost of BIM infrastructure development, the lack of regulations, the lack of process and so forth. In construction site phase, especially the analysis of current research trend about IT technologies, virtualization and BIM service, data exchange such as drawing, 3D model, object data, properties using cloud computing and virtual server system is defined as a most successful solution. The purpose of this study is enable the cloud computing BIM server to provide several main function such as edit a model, 3D model viewer and checker, mark-up, snapshot in high-performance quality by proper design of VDI system. Concurrent client connection performance is a main technical index of VDI. Through test-bed server client, developed VDI system's multi-connect control will be evaluated. The performance-test result of BIM server VDI will effect to development direction of cloud computing BIM service for commercialization.

As the Korea construction market has recent3y opened, the needs to restructure the design standard for the technical advancement in design is increasing. Therefore, we proposed the design standard of railway according to the direction, which is presented in this study that analyze the present situation of the previous design standard. The new design standard of railway was tried to definite a limit in each service stage. This design standard will improve the design quality and induce the accumulation of technology. In addition, it will solve the organic contradiction of construction service. As a result, this research will bring the improvement in the design standard and contribute to the development of Korea construction industry.

Private participation on public infrastructures projects is being promoted by governments of several developing countries, among them Colombia. As a result, several advantages such as service delivery efficiency, technology application and faster execution of the projects have been recognized. Hence, the Colombian Government is looking for schemes that allow the private investment in projects like hospitals, schools, prisons and public edification. In this paper, experiences in PPP from other countries were analyzed and adjusted to the Colombian environment. As a result, a model adapted to Colombia is presented, based on a well-developed case from Spain. The awarding process is defined by economic criteria, previous compliance of minimum technical exigencies. Once the infrastructure is operating, contractual periodical payments will be done, based on the performance of the facility.
