The large number of infrastructure improvements in Indonesia, causing the need for an underground investigation first, so that the buildings become sturdy and have a small risk of natural disturbance (landslides, land subsidence, earthquakes),etc. One of method used in underground investigations is the Ground Penetration Radar (GPR) method. The GPR antenna system consists of a sending antenna (transmitter antenna), as an electromagnetic signal transmitter and part of the receiving antenna (receiver antenna), that is as a detector of reflected electromagnetic waves. The scope of this research is to collect data in the field using the GPR method, and perform data processing using the Reflex-W application software to obtain information on the condition of the structure, depth of the building foundation, as well as its subsurface information. After all the information on the above values is obtained, we are able to manage the area of the local building more conducive and stable, especially those related to the dynamics of ground movement. GPR data collection was carried out for 3 days, at PANASONIC COMPANIES Tapos Depok, Jakarta – Bogor street on August 7th and 8th 2019. Then data processing and report writing were carried out at the office of Putra Cipta Jaya Consultant from August 12nd to September 8th 2019. Based on the results of the GPR inversion processing using Reflex-W software from 9 measured areas, information was obtained that the condition of the Building and its surroundings as a whole was still in good condition. There are only a few parts of the area that are attention in detail here, which is the office area, 1st factory building, 1st floors, as well as the generator building area, which in general, the three areas of this underground structure there is a land that moves down approximately 1-5 metres from the east and west direction. Therefore the building structure of this area is made a deep pondation, which is approximately 10 to 26 metres.
