£150m?????????? Whose valuation is this, the IBSA's?
Have they factored in the going rates which would be charged by tradesmen and everyone else involved in a major construction, but which of course the IBSA is receiving for free?
It could be that they will be using commercial construction companies to build portions or all of this. For instance, I believe all the steel construction going on in Warwick is being done by outside contractors, and I saw on this month's JW broadcast that the new facility in South Africa is being built by outside contractors rather than volunteers "to save time".
