That would be a question for Public Works. I don't know, because I don't hold that documentation. But if I may, coming back to your previous question, the RFP that PW put out asked bidders--and the banks ultimately won the RFP process--to do two tasks: do research on what would be an alternate accommodations strategy or method of managing the accommodation load that PW carries, and then depending on approvals in the system, do follow-on work with PW. That follow-on work, assuming approval flows, will lead up to the bidding process.
