Yeah Collison's article alluded to more mixed use functions within stadium/arena projects but they are still typically independent buildings within a project site, not always seamlessly merged together into a hyper integrated mixed-use function. It's complicated to get many different architects/project teams to coordinate the more integrated things get but collaboration tools will continue to get better over time that will allow for more complex interaction within projects. Hopefully stadium architects think about taking integrated public access even a step further than what's happening today.
I've been a solutions/enterprise architect on IT side and we've always been thinking about collaboration methods to accomplish far more complex things 5+ years into the future, refining wacky ideas. Collaboration tools are a part of that, allowing dozens of different entities involved around world to deliver extremely complex visions.
The common theme I've been pressing on the rag has been isolated islands vs. collaboration/publicly accessible integration on pretty much every level and this potential project is an opportunity to take collaboration to a new level. W/out an early integrated vision isolated islands can quickly result (Hi W&R project team).
