MEP works on infrastructure project - Piloting

As what i mentioned in few posting back, there is a few terms usually used in MEP infra works, one is what we called "utilities piloting", whereby that we actually excavate a few pit on a particular spot to see the physical body of the utilize like cables, water line, sewerage line. And there is where the cultural of 'korek tampal' which you always seen on all Malaysia road which cause damage to tyres and might also cause accident . How i wish, it could be better if our quality of as-built drawing is 100% accurate on site, but even authorities drawing is not on par as site most of the time. So, to confirm on utilities located below ground, only way is to do there piloting here and there and cause pot hole here and there.. hahaha....

Asides, there is some interesting information on doing work in infra project which involved some tools which you will never see in MEP building works.

There is this tool we called  "Precision Locate" which used to trace live cable beneath underneath the soil. It works by tracing the inductance which induced by current passing thru the live cable.

And with that, we can actually lowered our risk to damage any cable running underneath, but yet, this precision locate have the downfall as it does not able to trace telco cables or offline cables. 

I had did some research on the tools and found out this company called Radiodetection which actually invented that. Maybe you would like to download a user manual to know more about that ? Help yourself  !
