Abstract

Summary

Manado-Bitung Toll Road is one of priority projects announced by Indonesia President, Joko Widodo, to speed up economic growth in North Sulawesi Province. Kaima Overpass is one of many overpass which will be built to provide crossing between Manado Bitung toll road and local roads around it. Geo-electric method or known as Electrical Resistivity Tomography is used to get subsurface data and groundwater, while geotechnical method is used to get data about mechanical properties of subsurface material. The purpose of this research is to know the structure subsurface, estimated volume of hard rocks and soft rocks at Kaima overpass location. Kaima overpass location is dominated by medium rocks and hard rocks from Geo-electric data with value greater than 500 Ohmmeter and Standard Penetration Test N-SPT value greater than 15. The subsurface material structure consists of Andesite and Gravel Alluvium, which come from sediment / lava sediment from Mount Klabat.
