PERBANDINGAN BIAYA DAN WAKTU DALAM PEKERJAAN LISPLANK BETON DENGAN METODE PRECAST PADA PROYEK GEDUNG SMK N 2 KUTA SELATAN DAN METODE KONVENSIONAL PADA PROYEK GEDUNG SMA N 3 KUTA SELATAN

Abstract

Lisplank is a building structure that is able to give a touch of beauty to the roof of a building. There are many types of lisplank, especially concrete lisplank. Concrete plank work is carried out using two methods, namely conventional and precast. The South Kuta SMK N 2 Building Project uses the precast method while the South Kuta N 3 High School Project uses the conventional method. By comparing the costs and implementation time for concrete plank work between the use of precast plank and conventional plank and finding which method is effective in terms of cost and time. To determine the right choice of method, an analysis of costs and implementation time is carried out. Next, the analysis results are compared to obtain an effective method to use. Comparison of costs for carrying out each item of conventional concrete plank work costs Rp 1,056,435,018.63 and the time required to complete each item of conventional concrete plank work is 23 days, while the cost for each item of precast plank work is Rp 1,017,472,408.00 and the time required to complete each item of precast concrete plank work is 21 days. After comparing the cost of each precast concrete plank work item, it is Rp. 38,962,610.62 (4%) cheaper and the implementation time for each precast concrete plank work item is 2 days faster (9%) than conventional concrete plank work.
