Wait and see...
Actually the appeals could be interesting. The contract has already disqualified a number of well-known names for non-compliance on the initial submission. The original hardware requirements were precise to the point of obsession in some places, but tenderers were required to match the *exact* spec. A more efficient, better performing product with a lower number on the spec sheet would be disqualified, just to ensure that all the selected products were directly comparable.
On the same basis, disqualification threatens successful vendors who attempt to hike their prices in the first 90 days or after that without documentary proof. It's not a guarantee that vendors won't stick prices through the roof, but it's better than a single supplier contract with "put up or shut up" pricing.
Anon, because my employer hasn't been disqualified, but would be if we took issue with the inconsistencies in the awarding process.
