From the little I have seen to date, it occurs to me that the CAA have chosen over the years NOT to involve a true technology company in the design and build process. Your guys know what's needed and some companies can take their own technology and customise it to fulfil a need. That way, you end up with "off the shelf" hardware allied to bespoke or shared software systems which are easier to migrate and upgrade as requirements change. I don't think anything you have is or ever was "industry standard" so you have to re-invent the wheel rather than follow a technology path. Yes I do work in IT and I may be talking out of the fat bit I'm sat on but I'd be interested in feedback....
