Listening to the market I fully understand and appreciate why contractors would use new technology (like drones) in hazardous environments. My fear is, in the long run, will this drive down the need for skilled engineers onsite?  I suppose in countering this they would quickly argue that it may control salary expectations of hard to fill roles.

In January I held a meeting with a CEO of a large plant and construction firm.  Intriguing to hear his views on the market since starting in the sector in the mid 1970's.  His plant, and some skilled workforce, was used in preparing the Jaguar Engine Center off the M54 near Wolverhampton.  Interestingly he pointed out that the majority of the groundworks they were contracted on was completed remotely using robot controlled diggers etc.   Staggering to think when you see the size of it.  700 people are employed there.
