Purpose: The infill technologies is essential to ensure the adaptability and the repairability of Long Life Housing.
The study aims to analyze the infill technologies used in the testbed of Long Life Housing by measuring the productivity of infill technologies and establishing related precautions during its construction. The result of the study can be used as basic references for future infill constructions, especially in regards to the construction plan and work efficiency improvement and cost estimation. Method: Gypsum board walls, ALC block, Lsight weight steel ceiling and Dry Ondol System applied in each class of Long Life Housing unit are selected as main infill technologies for the analysis. In order to measure the productivity of selected infill technologies, their figures will be compared to that of brick masonry, Wood ceiling, and Wet Ondol System. Data for productivity analysis of the infill technologies is collected through the work sampling method on the construction site. Prior to the data collection, work monitoring plans and procedures are established and the construction order, required time for each unit work, experience of workers, and work amount etc. are examined. Daily work reports, videos, and pictures for each work are used during the data analysis after the construction. Result: The resulting analysis of productivity of infill technologies and established precautions can be used for the future improvement of infill construction and the quality of Long Life Housing. In terms of productivity of infill technologies applied in the testbed of Long Life Housing, the modular dry construction method of infill technologies is at least 8.2% to up to three times more efficient than the existing construction method. In addition, in-depth work monitoring on the construction site enables the establishment of precautions per each infill technologies such as securing water-resistant materials, developing adhesive fixing materials, preventing plumbing damage, reconfirming inserts positions, planning skeletal ceiling structure taking account of the beams and securing slab floor level uniformity. |
