My guess is that they will probably open up in blocks. Coming from the construction industry here you can't really have people (customers) walking around your job site. They will have to be able to keep a construction area fenced off from the public for production, safety, etc. Sometimes it also makes more sense (and quicker) to do certain parts of the project all together such as the exterior concrete, landscaping, etc. In fact many of the systems such as electrical and plumbing could probably be tied together between the individual units all needing to be completed before they open. Also if SXM operates anything like around here they will need to receive their final inspections from the "Building Department" before occupancy is allowed which usually happens when the work is 100% complete (or close). I could be way off on this but it is just my thoughts. Only time will tell the final answer.
