The components of a construction project's success include cost, quality, and time. Planning and management of detailed scheduling of activities are necessary to complete a project to get the most optimal results within a predetermined time period. In the Shangrila Hotel Resort and Spa project, the remaining work is building finishing. The percentage of project completion was still at 3% in July 2019, so in this condition, rescheduling was carried out with the right approach to determine the project time. The Shangrila Hotel, Resort, and Spa project rescheduling use the PERT and FLASH methods. This method uses a probability percentage rather than uncertainty probability when analyzing project completion time. The rescheduling period is 272 days. The PERT method analysis based on activities on the critical path produces a probability percentage of 79.39%. Analysis of the FLASH method by considering all project activity relationships resulted in a probability percentage of 90%. In making a schedule, you can use modifications from other project management applications, such as BIM (Building Information Modeling). \u0000ABSTRAK \u0000Pada umumnya proyek konstruksi selalu menerapkan konsep manajemen proyek.

It generates a budget change as a consequence. Project delays also occurred in Entikong PLBN Multi Purposes Building Project, West Kalimantan; therefore, an “addendum” time had to be submitted for the 31st week. According to the identified problems, the purpose of this study is to analyze the time acceleration to achieve project time reduction and cost savings. The analytical approach uses a fast-track method widely applied and proven effective in time reduction through overlapping the critical activities. The result of the project schedule shows that the normal duration of 359 days turned into 302 days; therefore, a reduction in time of 57 days can be obtained. Time reduction through project acceleration was 15,88% without causing an overallocated resource. The time reduction impacts project cost efficiency, especially in indirect cost savings of Rp 17.345.955. Implementing the fast-track method by paying attention to the allocation and availability of resources provides an optimal schedule. Thus, the risk of unrealized activities due to acceleration can be minimized. \u0000ABSTRAK \u0000Proyek konstruksi memiliki karakteritik unik, dinamis dan kompleks,sehingga sering ditemukan ketidaktepatan antara perencanaan dan pelaksanaan. Pada saat waktu penyelesaian proyek tidak sesuai dengan perencanaan, hal ini membawa konsekuensi pada perubahan pembiayaan proyek. Keterlambatan proyek juga terjadi pada proyek gedung serbaguna PLBN Entikong, Kalimantan Barat sehingga harus dilakukan addendum waktu pada minggu ke-31. Berdasarkan pada permasalahan yang teridentifikasi, maka tujuan dari penelitian ini adalah menganalisis percepatan waktu sehingga diperoleh pengurangan waktu pekerjaan dan penghematan biaya proyek. Pendekatan analisis menggunakan metode fast-track dimana telah banyak diimplementasikan dan terbukti secara efektif dalam mereduksi waktu penyelesaian dengan menata aktivitas-aktivitas kritis secara tumpang tindih (overlapping). Hasil penjadwalan proyek menunjukkan bahwa durasi normal proyek selama 359 hari menjadi 302 hari, sehingga terjadi reduksi sebanyak 57 hari. Pengurangan waktu dengan melakukan percepatan adalah sebesar 15,88% tanpa menyebabkan overallocated sumber daya. Pengurangan waktu berdampak pada efisiensi biaya proyek, yaitu penghematan biaya tidak langsung sebesar Rp 17.345.955. Penerapan metode fast-track dengan memperhatikan alokasi dan ketersediaan sumber daya, dapat memberikan jadwal yang optimal. Dengan demikian resiko tidak terlaksananya aktivitas akibat percepatan dapat diminimalkan. ","PeriodicalId":247229,"journal":{"name":"Jurnal Rekayasa Sipil dan Lingkungan","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134107187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
