A year and half to build? NO WAY.
Ok get this: Sportsnet in Canada just built a massive hockey set. The biggest set in Canada. Here's a pic of this set: http://www.leaderpost.com/entertainment/cms/binary/10251285.jpg?size=620x400s
That set was built in 3-4 months.
I work for a local tv station that launched last August. The facility i work in was built in about 3 months.
Yes they built it in 2 months, BECASUE THAT'S HOW LONG IT SHOULD TAKE.
