Finally, beware relying too much on construction estimates. Estimates are not exactly how many days it will take to construct your stadium, and on average, construction estimates tend to be rather optimistic. If you really, desperately need your expansion ready in 10 days, you should probably not trust a 10 day estimate from the construction crew.
isnt it in the real world if the contractor finish the project way pass the or pass the deadline they get penalized ?
