Frequent design changes or unnecessary project executions due to illogical practice, lack of feasibility study and, hasty drive have raised problems of budget waste in Korean construction projects. Since the MOCT (Ministry of Construction & Transportation) published Master Plan for budget efficiency for government projects, there have been a lot of policy efforts for budget saving. However, it has been pointed out that cost management at the pre-construction phase, which greatly influences the cost still remains imperfect. The target cost for government clients is not being estimated reasonably, and cost controlling at the pre-construction phase is not yet being carried out properly for keeping the budget. Therefore, improved construction cost management at the pre-construction phase was proposed in this paper. The cost management systems of advanced countries were investigated for it, and the issues were drawn from the cost management systems of these countries. On the basis of the issues, the present conditions and problems of domestic construction cost management at the pre-construction phase were analyzed for suggestion.

It is very important to manage the risk in building construction because construction process has too many internal risk compared with others. So construction managers need more developed risk management system than the Present. While the study for the solution and management of generated risk is comparatively enough, the effort to confirm the risk of construction phase on pre-construction phase haying an major effect on total duration, is insufficient. For supporting the schedule risk management of pre-construction, this study suggests the reclassified risk breakdown structure and the investigation form for advance preparations on pre-construction Phase, which help the Poorly experienced construction manager to make more correct decisions and efficiently to execute risk management.

In the face of the deterioration of tobacco manufacturing plant, we've got the plan for now manufacturing factory for the competitiveness, modernization, rationalization and environment. To achieve the goals, it was necessary to plan and investigate in the early stage of project. Consequently. We determined to introduce the CM in the early stage. We Performed the whole phase of CM services front the pre design phase services like feasibility analysis of site and building, plant master plan, selection of manufacturing facilities and drawing up the RFP, to maintenance management phase after the completion of a construction work. Contrary to the another CM projects, YongJu New Tobacco Manufacturing Plant CM organized the CM team with expert in field before the design development. This study analyze and evaluate the CM services of YongJu project which performed on the pre design phase. The purpose of this study is to emphasize the importance of pre design phase CM and support that CM services will start from the pre design phase.

The widespread of IT technology caused a remarkable change in many industries and the construction industry is also one of them being influenced in the form of CIC(Computer Integrated Construction) and BIM(Building Information Modeling). Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. Looking from this aspect, the greatest potential value lies in the planning and pre-design stage when considering the construction life cycle. In this paper, we propose a project on developing a 3D object oriented simulation system for supporting the pre design phase. We define the needs for such system through previous case studies and suggest a to be process model. Finally we anticipate the effects that the project will eventually contribute to the construction industry.

Recently, the importance of Pre-construction is gradually increasing in construction business. In addition to increasing greatness, Pre-construction affect to success or failure of projects. However, current domestic construction business doesn't constitute exact concepts and systems, and there are a lot of problems such as disorganize management of construction because most of Pre-construction depends on supervisors' experiences. Therefore, according as doing this study, We are going to analyze the tendency of Pre-construction step and bring up designed operation systems between departments in construction company. So we can expect to develop efficiency by excluding unnecessary operation and formulating more improved operation process.

The principal purpose of this paper is to present a novel two phases rational scenario applied in constructing an offshore monopod platform; in which the two phases are the all-ground horizontal construction phase and the post-construction phase. Concerning the all-ground construction phase, a brief investigation of its different stages, i.e., pre-fabrication, fabrication, pre-assembling, positioning, assembling, and surface finishing is introduced. The important practical aspects of such construction phase are investigated without going into the nitty-gritty of the details involved therein. Concerning the post-construction phase, a clear investigation of its sequential stages, i.e., lifting, moving and up-righting is introduced. A finite element model (FEM) of the monopod platform is created to perform the structural analysis necessary to decide the suspension points/devices and the handling scenario during the various stages of the post-construction phase on a rational wise. Such structural analysis is performed within the framework of the three dimensional quasi-static modeling and analysis aiming at simulating the realistic handling condition, and hence introducing a reliable physical interpretation of the numerical results. For the whole effort to be demonstrated efficiently, the results obtained are analyzed, the conclusions are presented, and few related recommendations are suggested.

The importance of project performance management as an alternative for solving problems is rising, which are followed by the difficulties of managing construction project in the construction industry. This research classifies and applies the potential improvement made by the construction practitioners. In order to apply influential factors for success on the construction project, the research identifies the relationship between the factors and performance management practices. In addition, in order to predict the results reflecting the project characteristics which are un-improvable by the construction managers in the initial stage of construction, the effect of project characteristics to the identified management practices have been drawn by performance area. Finally, in order to improve the predicted performance, this research provides a framework in setting valid best practices according to the performance areas through a statistical analysis between the best practices and project characteristics through the industry survey.

In 2011, the overall construction markets in KOREA are highly depressed due to decreases in orders of domestic construction markets in both private and public field. Also, we are losing competitive advantages over Chinese and Indian companies owing to the market shares on plant construction projects excessively. It is recognizable, under the circumstances that we are in interior position on high value technique to other advanced countries, that the orders of mega building and plant construction projects tend to be placed through the" Pre-construction Service", the importance of which has been emphasized domestically and internationally in recent time. However, current domestic construction companies show scarcity in understanding the general idea of the Pre-construction Service and fail in building proper structure of it. It is obvious that they cannot have any competent strategy to deal with Pre-construction Service. The Purpose of this paper is to analyze the core competence throughout preconstruction phase and, and make up for the weakness in the current pre-construction service process.

For deep basement construction of buildings downtown, the usage of Top-Down Method is increasing as much as ever from strong demand. One of the essential elements for the construction by Top Down Method is the pre-founded columns, which are installed in the ground and on which a building is installed. The fact that the pre-founded columns are placed in the ground makes them susceptible to its plumbness; this aspect distinguishes pre-founded columns from general columns. However, there are no criteria for erection tolerance. Therefore, field-measured-data concerning out-of-plumb of pre-founded columns in the construction field should be accumulated and investigated so that criteria and specifications for the erection tolerance of pre-founded columns may be established through the understanding of its aspects. In this paper, we investigate out-of-plumb of pre-founded columns for the construction case and analyze its aspects, and propose considerations for design and construction phase.
