| Abstract |
From now on, the aged apartment house is expected to increasing rapidly, So, we have to build a process of remodeling and develop the new technique. Demolition work is needed for systematic plan and management. However, contractors of the remodeling project established a rough plan and did not consider recycling wastes, safety of workers and structural stable of building. Therefore, we need a step to develop a assessment system, verify and make imagineering. This paper evaluated how much improve on construction speed, work efficiency, intensity of work and influence with another process comparing the existing method with the new demolition method. Developed the qualitative and quantitative assessment system with these output. The case study was carried out experimental group and control group, based on developed assessment system, which has the same condition. The existing method was made up of 3 steps- 1)Demolish windows, doors and iron goods, 2)Demolish indoor and outdoor walls, 3)Drop the waste. The new demolition method was made up of 5 steps- 1)Demolish windows, doors and iron goods, 2)Demolish the ceiling and wall's finishing materials, 3)Demolish the floor's finishing materials, 4)Demolish indoor and outdoor walls, 5)Drop the waste. Analyzed work time, idle time, the character of a work unit by mock-up test. This study's output is expected to establish a systematic process of new demolition method and have roots the maximizing waste recycling work in our construction industry. |
