Survey Georadar (Ground Penetrating Radar)

Ground Penetrating Radar (GPR) is one of the methods in geophysics that uses an electromagnetic wave source in the form of radar. GPR works by utilizing the reflection of radar signals that are transmitted into the soil layer. The signal will be reflected when there is a dielectric constant difference in the soil layer. So we get the results of subsurface images (radargram) with a certain level of depth from the results of the reflection of the radar signal received by the tool.

Survey Pipeline Oil and Gas

Radio Frequency Location (RFL) is one of the methods used to detect the presence of paths and depths of a metal-based utility network (pipes and cables) that are embedded below the surface of the ground by utilizing electromagnetic wave propagation (EM). The use of the Radio Frequency Location method with the Pipe and Cable Locator tool uses 2 (two) tools, namely Transmitter (Tx) and Receiver (Rx). The function of the Transmitter (Tx) is to emit frequencies, and Receiver (Rx) to capture frequencies .

Survey Geoelectrical

Geoelectric is one of the geophysical methods that produce electricity on the earth and how to detect it on the surface. By utilizing the propagation of an electric current, a potential difference value is obtained so the difference in resistivity values ​​below the surface can be known. The geoelectric method can be used for groundwater investigations, soil structure, mineral exploration and archeology and can be used to determine the potential for soil movement. Geoelectric analysis based on different materials will have different resistivity values ​​flowed by electric current.

Maintenance Drainage

To ensure the balance of existing urban drainage infrastructure and facilities, operation and maintenance activities are important activities to be carried out so that drainage infrastructure and facilities can continue to work to drain surface water and inundation not to produce negative impacts.

 

 

 

 

Maintenance drainage and repair activities are important activities to do.

  • Maintenance is a periodic activity carried out to ensure the functionality of the infrastructure and drainage works according to plan. Part of Maintenance is a part of Installation that is important before the repair and maintenance activities are carried out.
  • Repair (improvement) is an action to improve the drainage function that functions as

before.

Auger Drilling Rig

Auger Drilling Rig is useful for vertical drillings, such as making water catchment wells. Infiltration Well is one of the water conservation engineerings in the form of buildings that are made in such a way that the place to collect rainwater that falls in the shape of a dug well with a certain depth that functions as the roof of a house or watertight area and absorbs it into the ground. Infiltration wells function to provide artificial water recharge by injecting rainwater into the ground. The target location is the area of ​​water infiltration in the area of ​​cultivation, settlements, offices, shops, industry, sports facilities, and infrastructure as well as other public facilities.

Survey Leak Detection

Water leaks have always been a scourge for water companies (PAM) or Regional Water Companies (PDAM). A lot of money is useless just because PAM/PDAM cannot control water leakage. If the average leakage of PAM/PDAM water throughout Indonesia is indeed still quite high, which is 33 percent. Water leakage is usually caused by two things, namely technical leakage and nontechnical or commercial leakage.

Horizontal Directional Drilling

Horizontal Directional Drilling is one of the trenchless methods for installing subsurface utilities. Utilities that can be installed with this method such as clean water pipes, sewage pipes, oil/gas pipes, power cables, fiber optics, and others. HDD can be used to create underground lines that cross rivers, roads, and existing structures, so that utility lines can be built through them. Compared to digging the ground to install pipelines, horizontal directional drilling technology has installation costs 6-8 times lower.

Survey Topography  

A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot. The purpose of a topographic survey is to collect survey data about the natural and man-made features of the land, as well as its elevations. Output of Topograpy Survey is Topographic Maps that use the elevation.
contour lines to show the shape of the Earth’s surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes.
