Why utility detection and mapping so important? Before any commencement works at a construction site, it is essential for a utility detection survey to take place. By detecting and mapping the location of underground utility, companies can determine the feasibility of any sites. Utilizing modern techniques such as radio detection and ground penetrating radar (GPR) can help up company to save money and time.

Yes, there is a lot of advantages using this method. Advantages of Directional Drilling are:

Did you know that we can install underground utility without disturbing the surface? What technology that we can use to install underground utility?
Well, now we have Horizontal Directional Drilling (HDD) or as known as directional boring is an innovative trenchless technology that enables us to install underground utility without conventional open trenching. The process used to install utility services underground along the designated bore path over a distance. The process begins when a directional bore machine pushes a bore head connected to hollow pipe into the ground at an angle. As each joint of drill pipe is pushed into the ground a new one is added behind.
It is used for waterways, roadways, shore approaches, congested areas, environmentally sensitive areas and any area where other methods are more expensive. This method suitable for variety of soils conditions and pipe diameters. To more understanding, you can view the video below to get more information on how it works.

The fact is when underground cables are damaged it would caused dangerous to people. People can be killed and injured by an electric shock, electric arc (causing an explosion) and flames. The results from these injuries are severe burns to hands, face and body, even if protective clothing is being worn as shown in the pictures.
“Avoiding danger from underground services” (http://www.hse.gov.uk/) outlines unseen dangers arising from working near underground services – with guidance advice on risk reduction, especially concerning ground penetration or below surface operations.

By having buried utilities properly marked and identified, workers can operate equipment safely and minimize the amount of hand-shovelling needed to complete a project. Having a utility detection service also reduces the likelihood of cutting into a power line, gas pipe or other utility.

Locational accuracy of underground utility mapping is vital for the prevention of “blind” excavation. Data acquisition from GPR scanning is the key parameter determine the exact location of underneath utilities. The picture below shows that, the results of utility detection under real world conditions.
What did you guys know about Ground Penetrating Radar (GPR)? or it has known as Georadar equipment.
It is the technique that uses the latest radar technology for viewing of the image the subsurface. There are a variety of media to use GPR including rock, soil, pavements, structures and etc. It can detect objects of all composition, changes in material, voids and cracks.
Both Sterling and Blom recognise that there is a combined synergy of skills and market access between the two companies which, together, create a more capable service offering. Not only is this of particular interest to the electrical transmission marketplace, but also for the utility marketplace. By extending the total capabilities of both parties a joint approach to business development and project implementation will also create greater opportunities.
The collaboration will see namely the following collective services being offered to the marketplace;
Blom has long-established links with major engineering companies that offer services to the electricity transmission market, and has established links with a number of DNO’s. Sterling provides a wide range of services to this sector, including survey services, and has many of the DNOs as its established clients.
Phil Cooper, Director of Sterling commented: “The evolution of new laser technology, such as terrestrial and mobile LiDAR, will see the capabilities of surveying available to the Utility sector being more detailed and precise than has been previously possible. With the need for accurate asset condition and continual monitoring high on utility asset manager’s priority we are able to provide strong industry knowledge, in particular in the Energy Sector, with cutting edge spatial measurement technology and data management in the Geospatial market place.”
Simon Kraeter, Commercial Director, Blom UK added: “We know that the combined resources and experience that Sterling and Blom hold is an exciting prospect for DNO’s and believe that this collaboration genuinely offers a prospective ‘go-to’ supplier of survey services for the utilities marketplace as a whole.”
This is what happened if open excavation is not properly planned. Pipe burst due to undetected water pipe causing water interruption to residence and commercial areas.
