Needing construction agreement for large scale job with genereal contractor

[Nat C.]

I'm looking for a detailed written agreement to use for a large scale construction project.

All of the ones I've found online have catered more to small scale home renovation jobs. 

This is 100K+ build out of a large building.

The contract should include at what intervals GC is paid and what percentage and late fees if GC fails to finish on time, to name a few things.

Can anyone help me out?
