Abstract: Basement construction is done sequentially from the bottom to the top and this method known as bottom-up construction method. The work began on the foundation work, excavation work then furthered to the manufacture of columns, beams and plates are constantly up to the roof. Top-down construction method for basement construction is another innovations approach rather than bottom up method. Howard Johnson Hotel with 18th floors located in the middle of large city is considered in this study. The main contractor of the Howard Johnson Hotel project decided to apply top-down construction method for the 2 levels of basement. This study compares the construction methods of bottom-up and top-down in terms of time difference. The comparative analysis result indicated that the time requires for top-down construction method is 49 days less than the bottom-up construction method.
