I have just written bids for restaurants in several schools. You have to refer to the requirements of the bidding documents for this kind.

For example, the rental fee submitted to the school during the service period promises to be paid in full; After winning the bid, how much renovation cost is promised according to the requirements of the tender; How many workers are promised to be fully allocated; Promise to accept the supervision of teachers and students in the school according to the routine. These must be done in accordance with the tender documents!
