Integrated Project Delivery (IPD) is a procurement method that has been proved to improve construction project performance. However, in China implementation of IPD practices in construction projects is unknown though some researchers have studied the problems and constraints in adoption IPD. The purpose of this study was to explore IPD adoption in Chinese construction industry. Critical components of IPD implementation were reviewed, and questionnaires were distributed to collect industry views. The results revealed that IPD uptake is still low. In particular, the liability waiver and shared risks and rewards have been rarely used. In addition, co-location, value engineering method and the new compensation approach have also been hardly adopted. Some practices related to early involvement of key parties were adopted. Surprisingly, the findings indicate that the client has been continuously involved in the projects. The findings may imply that the legal issues and problems of contractual frameworks are still constraining IPD implementation in Chinese construction industry.

Traditional procurement methods have revealed many disadvantages especially the adversarial relationship between parties. After several decades of application, partnering has shown that it is an innovative arrangement that help to reduce many problems having existed in traditional arrangement. It can provide a win-win working attitude in a construction project. Partnering in construction has been applied in several ways in recent years in Vietnam. This mechanism can help both local and foreign construction participants to mutually offset their differences when implementing projects. This paper has investigated and introduced the incentives of partnering from Vietnam perspective in terms of foreign and local participants perceptions. It has been shown that 'to learn mutually among participants' and 'to increase bidding advantages' are the most important incentives according to foreign and local practitioners respectively.

The acceptance of unsolicited proposals (a private-initiated process) has been viewed by several governments as a means of encouraging innovative initiatives. However, the ramifications of this mechanism are still poorly understood. This paper analyzes a framework used by the Taiwanese government to evaluate unsolicited proposals. Taiwan's experience demonstrates the need for an improved framework in which key issues such as building consensus, maintaining a transparent procurement process, ensuring sufficient competition, and protecting intellectual property rights shall be addressed. In addition, the case study suggests that the roles of participants, the relationships and interfaces of activities, information flows, and decision making points should all be well defined. Some fundamental differences between solicited and unsolicited proposals are also discussed.

In recent years, the bid-rigging in public construction markets has been treated as a critical issue in Fair Trade Commission. The investigation revealed that the collusion was implemented extensively in every area from the material supply to the construction service of general contractors. This study reviewed the causes of the bid-rigging in public construction projects, and proposed the improvement plan to eradicate bad practices. Firstly, the causes and purposes of bid-rigging were categorized into two types of internal factors from construction companies and external environment factors influencing business activities. Secondly, the system development method was explained to detect the signs of bid-rigging based on the technical proposal documents in open tender. The detection systems of repetitive public owner also provide the function of sharing data on the companies and cases to violate the fair trade regulation. In addition, the problems and improvement direction of public procurement policies were discussed.

Web-based collaboration platforms present construction project teams with an opportunity to improve the efficiency of document exchange, better control project communications and enhance team collaboration. However, many construction professionals are still not convinced that these platforms, in their current form, are fit-for-purpose and yield sufficient efficiencies for the construction procurement process. In an attempt to improve the current ICT diffusion process, this paper evaluates the implementation of a web-based collaboration tool on the Lane Cove Tunnel (LCT) project in Sydney, Australia. Moreover, the paper provides strategies for achieving more effective implementation of web-based collaboration platforms in the construction sector.

This paper introduces recent applications of three-dimensional building/construction data modeling (3D) and building information modeling (BIM) to large-scale complex building construction projects in Japan. Recently, BIM has been utilized as a tool in construction process innovation through planning, design, engineering, procurement and construction to establish a front-loading-type design building system. Firstly, the background and introduction processes of 3D and BIM are described to clarify their purposes and scopes of applications. Secondly, 3D and BIM applications for typical large-scale complex building construction projects to improve planning and management efficiency in building construction are presented. Finally, future directions and further research issues with 3D and BIM applications are proposed.

On the construction area, Information Technology (IT) has been a considerably significant part over the all phases; plan, design, procurement, construction and post-construction. For example, CALS, CITIC, PMIS, FMS, BIM and etc, designed and applied for managing construction industry are already valuable to improve on the Construction Management (CM). To develop these management methods, lots of mixed-systems are studied and progressed so far. In this paper, more useful and efficient system modules are proposed through investigating PMIS cases implemented, especially medical projects, to improve into FMS on the post-construction. Because most PMIS on the construction phase is used not to continue as FMS, considerable cost and time is consumed to rebuild the system, even both systems have common modules. As these wastes are faced to design systems, the important modules on PMIS are derived and analyzed to apply to FMS to save time and cost on CM.

현재, 한.미 ROU 협상당시 의도했던 목적은 이미 달성되었다. 우리나라는 WTO 정부조달협정에 가입하여 협정을 준수하고 있으며, WTO 정신에 입각하여 통신장비 조달도 공개, 공정, 비차별 원칙에 따라 운영하고 있다. 양허대상 통신사업자인 한국통신의 경우, 1997년 10월부터 출자전환과 함께 조달시장이 전면 개방됨에 따라 전세계 모든 공급업체에 비차별, 내국민대우를 보장하고 있다. 또한 한.미 ROU에 명시된 바와 같이 한국이 WTO 정부조달협정에 가입함으로서 한.미 ROU에서 배제조건을 충족시키고 있다. 더불어 현재 KT의 정부지분은 100% 민간에 매각되어 완전하게 민영화되었다. 그럼에도 불구하고 한.미 ROU는 WTO 정부조달협정으로 대체되거나 종료되지 않고 있어 양허대상인 통신사업자는 한.미 ROU의 본래의 취지와는 달리 경영의 자율성 침해와 조달의 비효율성 증가로 인하여 많은 추가비용을 지불하고 있다. 따라서 본 고는 국내통신사업의 발전과 규제완화라는 측면에서 정부조달협정 중에서 가장 파급효과가 큰 한.미 ROU의 개정협상을 위한 방향을 모색해 보았다.

Robot-based layout automation has been recently promoted for the purpose of improving productivity and quality. Marking robots have various functional demands to secure marking precision and environmental adaptability. In particular, in order to automate marking work of building structure, correction of the marking line through position recognition of rebars placed is required. Because the rebars must maintain a constant cover thickness from the formwork surface, if the rebars are out of planned position, the rebar or marking line need to be corrected to secure the cover thickness. Thus, the marking robot for structural work needs to have the function for determining the position correction of the rebar or the marking line. In order to judge the correction of marking line, it is required to measure the distance between the planned marking line and the rebar placed. Therefore, this study proposes an algorithm that can measure the distance between the planned line and the rebar, and correct marking line for the automatic operation of the marking robot. The results of this study will be utilized as a core function for unmanned operation of the marking robot and contribute to securing precise marking by reflecting construction errors.
