Construction management has been suffering from many problems, which need to be solved or better understood. Most of construction projects have not achieved efficiency as expected. In this context, waste was also considered as a problem of efficiency decrease, and poor production planning was considered as a cause for waste. This study was conducted on the basis of waste concepts and production planning processes based on the philosophies of Lean Construction. A survey to find out the relationship between them was carried out through questionnaire, which was answered by experienced people in construction projects. The results have shown that frequency of wastes occurrence is quite high, and production planning processes are superficially performed in construction phase. There is a significant negative relationship between production planning and waste occurrence (r = -0.262). Weekly Work Plan (WWP) is the most dominant plan for waste control with seventeen in total of nineteen waste factors, and phase plan is the most dominant plan for two remaining waste factors. A case study was adopted to validate the relationship between production planning and waste occurrence. The results showed that the better the project was planned, the fewer the waste would occur on construction sites.

The domestic construction industry need to do productivity improvement through technology development than improvement of manpower control or system and develop competitive power through technology in international construction market. Upon this, government for elevation of technological level enacts and operates the advanced construction technology endorsement system but is not looking at effect as that the actual use-results also expected first. Therefore, in this paper, present improvement and direction for activation plan of construction new technology development through comparison with other connection system, literature investigation and questionnaire after grasp present condition of the advanced construction technology endorsement system with specialty construction company as the central figure which occupy most of appointed new technology.

Purpose: The construction of New Han-ok style public buildings is a construction that can not be seen in traditional Han-ok, and it is a construction that combines traditional wooden structure, RC structure, and steel structure. Therefore, construction different from general construction is complicated and complex. It is necessary to accurately understand the construction method of each field rather than the general construction management method and study the method suitable for New Han-ok style public buildings. Also, since the New Han-ok style public building business is the first business to be introduced in Korea, new process management is needed rather than general process management. Method: The research method is as follows. Analyze process management through theoretical considerations and analyze the differences from general construction projects. Next, we want to identify the characteristics and problems of the process control method applied to real cases. Finally, the results of this analysis suggest ways to improve process management. Result: Therefore, it is necessary to establish a precise plan from the basic design to the construction of the public building construction management. In addition, careful planning should be made so that the supply and demand of materials and the supply and demand of personnel can be achieved smoothly.

This study aims to develop a performance evaluation system for the Construction Factory(CF). The CF is a kind of full automation system for building construction which consists of the lifting system for building materials, the built-up unit for steel structural components, the bolting robots, the control center for the site management, and the site covering system. The CF is developing now as a project of the construction automation and robotics. In this study we firstly reviewed the state-of-the-art of the construction automation and robotics in the foreign and the domestic, and investigated the precedent case of the CF such as the SMART System of Shimizu Co., Japan. We believe that without an objective evaluation of the results there won't be growth in technological R&D. Therefore, this study sees the developing CF as an new technology and method in building construction, and proposes the direction and frame of the appropriate evaluation which can be applied into the CF.
