EPC contractors have made continuous efforts to develop integrated project execution methods to improve the performance of industrial plant project. In particular, the concept of Advanced Work Packaging (AWP) has been recently presented by readjusting the existing "Work Packaging" concept as part of the integrated project execution method from the project life-cycle perspective. However, Korean EPC contractors are still unfamiliar with the AWP implementation. Thus, this study aims to identify the organizational competency factor for effective implementation of AWP. For this purpose, first, this study identified the expected risks in AWP project and the 29 organizational competency factors to manage risks. Second, five experts verified the suitability of factors and supplemented the factors. Finally, 37 factors were identified as organizational competency factors for implementing AWP.

Recently construction industry has faced new era as following the advances of IT technology. It becomes possible that information and knowledge among people are exchanged actively thanks to computer-based tools. In fact, the tools, PMIS(Project Management Information System) and KMS(Knowledge Management System) already have been introduced to constuction industry successfully. Lately IETM(Interactive Electronic Technical Manual) is tried to be one of these systems. This trying is being enlarged that the IETM's concept is changed to administrative and legal process provider throughout the lifespan of construction projects. However, it is hard to define construction IETM in mega-scale project like urban regeneration project because construction projects are complex and have diverse stakeholders. These properties may make the IETM ambiguous system. To do define IETM as a administrative and legal process provider, this research will conduct survey and interview, then analyze its own properties and find out design strategies. Based on the properties and strategies, suggesting IETM's system demands and architecture of urban regeneration processes.

Due to various reasons (normally financial constraints in developing countries), it becomes common to change of the business model from state-run projects to Private Investment Projects (Public Private Partnership) in the global railway businesses. However, due to the nature of railroads compared with other types of infrastructure such as roads and others, railway business require considerable construction cost and O&M cost through the business development, construction, and operation and management stages. Therefore, private investment railway projects, especially in developing countries, can be problematic in terms of the potential for uncertainty when return on investment cannot be guaranteed. In order to strengthen the competitiveness of domestic companies when entering overseas railroad PPP projects, this study proposes PPP-related risks and their countermeasures by reviewing global railroad trends and identifying Korea's weakness in managing international railroad projects.
