Enterprises should set up realizable goals and continually control the goals from apprehending whether they can be realized or not so that the enterprises grow consistently. Furthermore, from supplementing parts to be improved, goals are reset and the result should be controlled in order to fit to them. Lately, a lot of discussions about the results of organizations, projects, and companies are being realized in construction field. Particularly, in construction management, effective and professional control activities throughout the life cycle of facilities as well as the stage of business implementation of construction work are needed. About the result measurement of the construction management, lots of most domestic researches stay in the level of establishing basic concepts. Also, since characteristics of the construction field and the construction management were not reflected properly, it is in a situation that the result control system is not applied to on-site real works. Hence, this study intends to suggest fundamental data for measuring objective results from extracting result areas and key performance indicators of the construction management using Balanced Score Card.

The government, in order to settle and activate the use of Construction Management (CM) method, clarified the legal Issues pertaining to infrastructure development and is taking an active role to promote CM through government sponsored pilot projects. However, when a CM method is applied to a turn-key protect, many applicational difficulites are expected. With design and construction are performed under the simple responsibility in a turn-key method, roles of CM's is overlapped. Also, the characteristics of turn-key method are not reflected to the present $\lceil$CM Work Guideline$\rfloor$. Over the years, various problems have been identified from turn-key projects. Korea's $\lceil$CM Work Guideline$\rfloor$ is more inclusive compared to the CM services of CMAA and overlooks the importance of CM's roles in pre-design phase. In this study, CM's roles of pre-construction phase (pre-bidding, bidding, detail design, contracting) in construction turn-key projects were identified and complementary policy for institution was suggested. We further look into dividing the roles of the CM at turn-key project Into professional role and emotional role. Also, we speculate problems of the existing experience in turn-key projects and suggest a rough methodology on how these concepts can be adjusted for improve the turn-key method.

Because designers want to express various elevation, architectural concrete has recently paid attention to finish material and has increasingly used in the construction. architectural concrete needs more careful and professional supervision works such as controling quality of color, texture, construction plan, and design plan. none the less, It is not clear to define process and manage methods for the construction life-cycle, which causes the expense to increase and the quality to be poor. this study will analyze concrete finish method by dividing three parts which are common, exposed and architectural concrete finish method. definition and the limit of application in architectural concrete finish method will be present by comparing three methods. Throughout an interview with a staff in charge and a case study, this paper shows the requirement and the keynote of management which are divided by three steps; the design, construction and maintenance. finally, this research provides management methods of individual steps for effective construction.

Nowadays, the existing manual method for recording actual progress of the construction site has some drawbacks, such as great reliance on the experience of professional engineers, work-intensive, time consuming and error prone. A method integrating computer vision and BIM(Building Information Modeling) is presented for indoor automatic progress monitoring. The developed method can accurately calculate the engineering quantity of target component in the time-lapse images. Firstly, sample images of on-site target are collected for training the classifier. After the construction images are identified by edge detection and classifier, a voting algorithm based on mathematical geometry and vector operation will divide the target contour. Then, according to the camera calibration principle, the image pixel coordinates are conversed into the real world Coordinate and the real coordinates would be corrected with the help of the geometric information in BIM model. Finally, the actual engineering quantity is calculated.
