Analysis of Function Improvements Due To Changes In Core Zone Material Based on Value Engineering at Urugan Batu Dam

An embankment dam is a large artificial made by placing and compacting various compositions of soil, sand, clay or rock. One the rock fill dams located in Buleleng Regency, Bali Province, namely Tamblang Dam which planned to be utilized meet raw water needs Regency particular Province 510 liters/second, irrigates irrigated rice fields Bungkulan Bulian with an area 588 Ha, as micro hydro power generator 2 x 269 MW, well other uses for flood control tourism. At first was upright core material. After conducting test pits at 30 borrowed areas soil investigations independent laboratory, volume zone material according specifications cannot There are alternative solutions problem, bringing from outside project site changing original design into asphalt concrete core. This study applies Value Engineering (VE) method increase function fixed cost will obtained reducing costs increasing functions.
