Until now, the eco-friendly construction (green construction) has been focused on reducing environmental impacts in use(operation and maintenance) phase. Considering the environmental influence along the life cycle of construction project, the impact in execution phase is rather lower than that in use phase. However, that impact is thought to be greatly decreased by well-organized activities. Based on its urgency and requirement for timely action, this study aimed to discuss the greenhouse gas (GHG) reduction plan in execution phase from a broad perspective. To achieve this purpose, the green building rating systems in domestic and foreign countries have been reviewed, and the practice in Japan was investigated. In order to improve current on-site greenhouse gas management, the integration among construction phases, participants, and environmental factors, and institutional supports are required as well as the contractor's efforts.

The Development of Cost Management is embossed efficiently to use the budget for the construction industry. The government is exploring every efforts and polices to control increasing the budget for the construction industry. However, despite of the government's efforts, researches are insufficient for a cost management of development. Also, the changed cost of construction by frequent plan change is caused of decline in quality etc during an accomplishing project. Therefore, in this study, analyzed about principal official phase of design phase to solve the problem. In order to define clearly the target cost concepts in the planning phase apply to the DTC(Design To Cost) concept and technique at the development of cost management process which will be able to manage the enterprise expense. It's process is expected with the fact that will be the possibility efficiently of fixing target cost in the planning phase by the construction client and designer.

Construction project is necessary element for human life to upgrade the quality and convenience. However, due to its contradictory nature to the environment conservation, environmental pollution and damage, deterioration of natural scenery, noise/vibration, water quality pollution, etc. caused in the process of construction greatly affect the environment. The purpose of this study is to propose checklist for environment management can be used in construction phase. For this, we went ahead with the research by studying the existing research related to environment-friendly construction project management both at home and abroad, investigation and analysis of environment-related laws and ordinances, and drawing the checklists for natural environment and living environment at the construction phase. As a result, we were able to compile a checklist for nine items including geological features, animals and plants, use of soil, quality of air, water, and soil, construction wastes, noise, vibration, recreation, and sceneries. The checklist is structured in 4 grades and coded so as to allow it to be developed with the use of computer system in future. We hope that the checklist presented in this study will help lead the managers at the construction phase in construction development sustainable from the perspective of environmental conservation.

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.

Since it is common that design BIM data created by designers and engineers do not afford to consider constructability for the site, it is usually necessary to optimize the design BIM data to construction BIM data. While this optimization process requires various design updates depending on the construction methods and requirements, most designers in the projects do not participate the construction phase, which can arise another obstacle factor in utilizing construction BIM. In order to prevent this issue, we need cooperation system, where all the parties work together from the initial stage of project to create quality assured BIM model. However this kind of system is not realistic in Korea with most of the working processes being conventional yet. Therefore, at this point of time, it is realistic for us to secure basic construction qualities in the design phase and keep those qualities by the construction phase. This study suggested a relevant quality management plan for BIM usage in construction phase.

To secure quality of dam construction needs appropriate construction duration. Tight construction schedule may have negative influence on infrastructure quality, work safety and maintenance cost. It is necessary to reflect proper construction duration in the planning phase. There have been standards for estimating construction duration of building and industrial complex development but dam construction have not. In order to estimate construction duration of CFRD, feasible study reports and design reports were analyzed to acquire available information. After that, considering on construction duration methods such as comparison with similar cases, approximate estimating formula, approximate quantity assumption were adapted to Critical Path items. Hence, this study present framework for construction duration estimating of CFRD in the planning phase. This framework can be applied other types of dam along the same line.

Building costs means capital costs which include cost of land, costs of acquiring and preparing the site, construction costs, professional fees, furnishings, cost of financing the project. and cost of management required to run and maintenance the building for use. There are several phases that determine the building costs : design phase, construction phase, and operation & maintenance phase. So, the cost of work could be set against the examining the full range of complexities that a building program might contain. To solve this problem, it needs to compute building cost systematically. This is still in the development stage, awaiting the organization of rational cost data base. The method of cost saving by cost control could be constituted by detailed knowledge of building costs for all possible combinations of components and subsystems that can be assembled into integration model of cost factor on each phase of project development. The model of cost saving in each building phase is available for procedures of cost control of building systems.

Recently, countries in the South-east Asia are making efforts to enhance the construction industry system and introduce the construction management system. However, it is challenging to apply construction management in site due to lack of technology and professionals for CM. This can result in frequent safety accidents, cost overrun, schedule delay, etc. Therefore, it is necessary to carry out a clear evaluation of the overall situation regarding the level of technology and required competency. The objective of this research is to investigate on which management skills and items for CM are required to improve the construction management skills in South-east Asian construction industry. As a result of the questionnaire, most of the officials selected that the design phase and the construction phase are important works, and the engineers evaluated activities during the bidding phase, the design phase and the construction phase as important works for construction management. However, in most of the results, it was observed that the current competency of Vietnam construction is insufficient compared to the evaluated importance of the skills. This can be explained by the fact that they are not capable of managing construction projects effectively as compared to the importance. The results can help to realize the inadequate aspects of local construction industry, which will be the basis of improvements. Also, it is expected to be supportive to improve construction management in the countries and also provide indicators related to work stage or technology that should be acknowledged when establishing the advancing strategy for Southeast Asian countries in the future.
