That would also apply to the power lines which were installed and also the water mains.
Now that opens up a major issue.
As a quantity surveyor, that would be a large task to assess, but it is possible to go through the supplier and subcontractor invoices to separate the costs.
I am currently working on a job where I am dealing with over 40,000 invoices.
All I would need is the drawings with demarcation of the extra over for stage 2, the invoices and the computer print out of costs.
But this is not going to be done before the vote, but has to be included in a re-adjustment of the share price offer.
It appears that the shareholders have been duded by the Board.
