Abstract

The selection of construction materials plays an important role because it directly affects the quality of the building, as well as the time and cost aspects of the work implementation. In general, the material used for wall work is lightweight brick, along with the times various new materials have been introduced to increase the efficiency of time and cost of work, including precast concrete. These two materials have different implementation methods that can affect the difference in time requirements and implementation costs. This study aims to compare the percentage of time and cost differences in the work of the outer wall facade of the building by modifying the use of precast concrete walls to lightweight bricks. The research methods used include direct observation in the field and literature study. The analysis results show that using precast concrete for building facade walls is more economical with a cost difference of Rp.6,692,903,056.39, or about 26% cheaper than lightweight bricks. The use of precast concrete is more affordable but requires stricter and more thorough supervision during implementation. The duration of time on facade work using precast concrete walls is also more efficient, with a completion time of 8.6% faster or equivalent to a savings of 17 days compared to using lightweight bricks.
