2. the are no fixied fees for each step of expansion
4. I.e. Adding 2000 seats to a 8000 seat arena (adding 25%) takes longer than adding 1000 and 1000
Are you sure?
Bleachers: 200$ for seat
Lower Tier: 700$ for seat
Courtside Seats: 2000$ for seat
Luxury Boxes: 16000$ for seat
Since I started to expand with 6,000 seats until now that I have more than 10,000, the construction prices have not changed. And according to what my colleagues have told me, the stadium with more than 22,000 seats has not changed either.
Bleachers: 249 in 6 days, 499 in 7 days, 999 in 9 days, 1999 in 13 days. 1 more day for 250 seat extra.
Lower Tier: 166 in 6 days, 333 in 7 days, 666 in 9 days, etc. 1 more day for 166 seat extra.
Courtside Seats: 99 in 6 days... 1 more day for 100 seat extra.
Luxury Boxes: 48 in 6 days
With the data I have, the construction budget, it would take longer to build 1000+1000 seats (20 days) than to build 2000 at once (14 days). Unless the builder is scamming me, which I highly doubt given their reputation for meeting deadlines and budgets.
