The Basic Things To Be Aware Of About 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.

The mains are quite many and some of them may probably include telecommunication lines, natural gas, electricity distribution, fiber optics cables, cable television, street light wires, traffic lights, water drains, storms drains, sewage drains and also wastewater pipes. The above listed lines are not the only ones competing for a space underground.

The first thing one should do before starting any form of digging is contacting state authority or local government and give them a copy of the map of the location where excavation is to be carried out. There are few locating methods as well as detection techniques used in this field. Different detection as well as different location techniques are today being applied for different types or forms of underground lines.

The other reason why public utilities go underground is for convenience reasons or aesthetics. But before any digging is done or commences, the city local authority or government often need that underground systems be located, denoted and also approved to ensure it is in right of way of the public. Materials used for manufacturing underground lines are different for different lines. It is because of such difference that different detection techniques and different location techniques must be applied.

Materials used to actually manufacture metal pipes or even metallic cables usually differ from one pipe to the other. Following this reason, the detection methods and location techniques applied should be different for each type of material. Those pipes manufactured generally using metallic materials, electromagnetic equipment application is the best for locating them.

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.

There are some companies however that permanently like to mark their utilities with things like posts, bollards and concrete marks especially for line that carry petroleum products. The markings are of great importance to the people living around that area. Some people unknowingly may settle on lands where petroleum pipes are passing underground hence endangering their lives.

Non metallic materials are plastics, fiber optic cables, concrete and also ceramics. But GPR is able to accurately and precisely detect and pin point location of non metallic objects. GPR has the capacity to detect even pipe leakage in some instances. They can also be used to measure accurately the depth of the object. GPR is associated with reduction of cost for the whole project. This is because of its precision and its ability to protect structures from damage.
