You are all not big or clever. If you had called the man you would have found out that the work is actually on the old London Bridge that was transported to and re erected in Ariziona many years ago.
The reason they need scaffs there now is that it is a top secret fast track project organised by the US government. The bridge is going to be dismantled and then re erected across the pacific so the troops can get to North Korea quickly.
Watch this space for future jobs in North Korea!!
I just phoned for this they asked see if I worked before on London bridge my answer was no so I was unable to get a start
