COST COMPARISON STUDY OF PLASTERBOARD DRYWALL PARTITIONS VS. TRADITIONAL MASONRY/CONCRETE PARTITIONS IN HIGH-RISE RESIDENTIAL BUILDINGS, SHANGHAI

摘要

A cost comparison study of plasterboard drywall partitions vs. traditional masonry/concrete partitions in High-rise Residential Buildings in Shanghai is summarized. The study was purposed at demonstrating the cost advantages by using plasterboard drywall partitions over the traditional masonry/concrete partition system in high-rise residential buildings in Shanghai region. With the drywall plasterboard partitions substituted for the masonry/concrete partition system, it is found that the main structural construction cost can be reduced by 10% for the typical building studied. Besides, there is a massive reduction of laboring, and the construction period for the building is expected be reduced by 40 days approximately. An extra usable floor area of 360 m~2 is also expected for the building redesigned. The study reveals the positive cost advantages of high-rise residential building constructions with plasterboard partitions over those with masonry/concrete partitions. Although the cost comparison was based on a real-life high-rise residential building in Shanghai, the results can be applied to any regions where the material and labor rates are similar to those in Shanghai.
