Elements To Consider When Conducting A Utility Locating Sydney Services

By Douglas Martin


This is a process that deals with identifying and marking of utility mains. These include telecommunication lines, television cables, traffic lights, electricity distribution among others. Each utility is located using a different technology since no technology can be used for both utilities. For this reason, factors affecting Utility Locating Sydney services has to be known and are discussed below.

The season of the year is a crucial aspect to observe. The detection is affected by the amount of vapor that is available underground. During rainy seasons, there is a lot of humidity thus hampering the whole process. This is because the sensors will be limited to detect readings that are below the water table thus ineffective. It is therefore advisable to carry on the process during dry seasons when there is no vapor.

The nature of apparatus to be surveyed matters. There is a range of systems used in the detection process, and they work differently. Some can only detect materials that are nonmetallic while others will specifically detect metallic ones. Further still, there are electromagnetic ones that can detect both metallic and nonmetallic material. For this reason, it is imperative to know what is to be detected to employ appropriate techniques.

The type of soil within the area is also a limiting factor. The signal penetration of technologies used depends on the nature of the soil. Clay and sandy soils are highly conductive and saturated respectively thus causes rapid dissemination of signals. Therefore, the penetration of a ground radar signal is reduced to less than one meter. For effectiveness, terrain conductive method should be used for conductive soils and resistance method on highly resistant soils.

The category of the utilities that must be detected should be known. They can either be sound or currently related thus limiting the kind of methods used to detect them. Water and gas utilities produce sound as they move, thus detected by acoustic systems. Unlike water and gas, power produces heat thus the ranges of temperatures are recorded, and this is by use of thermal surveys.

The distance between the surface and the underground matters. The sensitivity of different properties vary and thus it can be noticed over varying lengths. For example, metals are detected within a short depth not exceeding one meter whereas plastic can be detected up to five meters. Therefore, people should know what they are to detect to enable them use suitable detecting machines.

The level of substances in the transmitting vessels should be observed. This is because they affect gravity sensors due to their varying densities. For instance, an empty water pipe can be easily detected than one filled with water. This is due to the difference that exists between the air and the surrounding soils.

The cover of the surface is also another limiting factor. To obtain readings within a short time, the surface above which the mains are installed need to be clear. Meaning there should be no trees or other things that will affect the operation of these detecting devices. Besides, it has to be flat to ensure that the sensor and the surface are in contact for effectiveness.
