The Facts To Know On Utility Locating Services In San Jose

By William Fox


This is quite an interesting job to do and requires professional or trained personnel to accurately do the job. Locating of utilities is generally that process undertaken with an aim of clearly identifying and accurately labeling some utility main that are buried beneath the ground. Many public facilities in several cities or towns are actually passed from one point to another or from one location to another through underground means. Utility locating services in San Jose are essential for anyone thinking to build or carry out a construction.

Clearly identifying underground facilities is today becoming a challenge due to vast array of cables or line buried in the ground. Hence, as the ground beneath our feet continuously becomes congested with such lines, it become very important to locate the exact location of gas lines, water pipes, fiber cables, television cables, natural gas line, wastewater pipes and telecommunication cables before beginning any construction.

Other facilities competing for underground space include big oil pipelines, gas pipelines, communication lines for national defense, mass transit, road tunnels and also rails. Many public utility system found in San Jose, CA are actually run underground. The nature of some public facilities requires them to be run underground.

Aesthetics or convenience is basically another reason why such important utilities should be passed underground. It advisable that before the commencement of any digging, the local authority or government of that city is informed so that they can help in first locating all utilities passing within that area and to appropriately mark them. After this has been done, then excavation can then proceed.

For pipes manufactured using metal pipes or metal cables, electromagnetic equipment which are fitted with transmitter and also a receiver are often used. But of course not all materials are metal. For non-metallic pipes such as concrete pipes or plastic pipes, other kinds of radiolocation is mostly used or sometimes ground penetrating radar that is modern is also used.

The method is considered non destructive since it is normally based on magnetic or electromagnetic principles. It can easily identify and also map location of sub surface mains and reinforce steel within concrete without cause any damage to structures and surfaces surrounding. It can effectively insect sites non intrusively, assist in avoiding project down time and also preserve the structure.

The other benefit is accurate location and detection GPR provides. The most preferred solution for effectively detecting utilities is pipe and cable locators that are based on principle or canon of electromagnetic induction. The major limitation of such locators is the failure to detect materials which are non metallic.

The markings are mostly done for venting requirements and sometimes it serves as an indicator of underground facilities with ability to harm people if disturbed. In many countries around the world, they use color coding for easy identification. Such color codes are often used to easily identify already existing underground utilities or facilities in any construction area to generally protect them from being damaged during the process of excavation.
