Cost Analyze Of Dewatering Work At Foundation Construction (Case Study Anugerah Palace Hotel ( HAP ) Project in Surakarta)

Abstract

The problems that were encountered in building construction with a basement is the presence of water in the excavation area is located below the ground water table. One of the cases is the construction of Raft foundation Hotel Anugerah Palace (HAP) Project in Surakarta. In which construction in order to dry from puddle, so made the construction of foundation finished without disruption. To keep the area foundation worked well and dry, the foundation construction used dewatering system. Dewatering system at Hotel Anugerah Palace (HAP) Project is a predrainage method and open pumping method. To analysze dewatering system at Hotel Anugerah Palace (HAP) Project a series of studies were conducted i.e : studies the implementation of foundation method, dewatering method, analysis of standing water volume with number of pump and analyze of toal cost dewatering. This is expected to be a parameter in the analyze of the effect puddle water on the foundation and dewatering costs to complete the implementation of the first stage of the project construction problems effectively and efficiently. The result shows in the Hotel Anugerah Palace ((HAP) Project Surakarta, normal water volume 2,049 m3 / 2 minutes (cycle pump will run every 5 minutes because the system live two minutes three minutes off). Requires six surface pumps, four submersible pumps and two engine pumps (incidental). With details of operational cost analysis, equipment materials and labor to the use of dewatering is completed during the 1.5 year total cost ± Rp 267,978,500, -
