Construction Period Analysis of HPC Method by PC Construction Project Cases in KOREA
Keywords:HPC method, hollow PC column, construction period, half-slab method
This study was conducted as basic research for applying HPC method to building construction sites. HPC method was compared with an existing method (Half-slab method) for the analysis on a construction period. As a study method, this researcher analyzed the drawings and construction plans of the cases of the buildings constructed with Half-slab method. The analyzed seven buildings used as cases were domestically built within the last 5 years. According to the analysis, cases A and B that had columns divided for construction shortened about 16% of a construction period. The schedule of column assembly work was analyzed to be shortened much. That is judged to be because the use of a hollow PC column leads to a decrease in the number of columns. In particular, if HPC method is applied to a building construction site using large columns, it is analyzed to shorten a construction period more than the existing Half-slab method.
