Sounds like another con, like the plaza refurb a while back.
Local Mayor/Councillor awards contract to friendly builder/contractor. (cheapest estimate out of 3, the other 2 will get the next jobs). So 200K, I imagine the local rate for a street paver would be no more than 25K per annum. So 150k would be enough to employ 6 fellas for a year! And allow 50k for materials, if they are matching existing - that would be an awful lot of block paving!
I think the real cost is closer to 100K, and the other 100k to be split between builder and council.
Of course I am only winding every one up, and that type of fraud would never happen in Spain.
Let's hope this time it won't take so long!!!
