LA Weekly offers this lengthy rundown of the process and how things haven't gone to plan.
"The reasons behind the fiasco are as numerous as they are complex. But at its core, it's a simple story: Somebody had a clever new idea, and it backfired.

He sold elected officials on a new type of contract, which he said would bring the project in cheaper and faster than it could be done by traditional means."
