The bill of quantities is the contract
A poorly described item is a scheduled extra. The precision of the bill of quantities determines the final price far more than negotiation does.

Points of attention
The real pitfalls of the trade — the ones that cost money when nobody watches for them.
Additional works
They are normal; what is not normal is discovering them on the final invoice. They are validated as they occur, in writing.
Provisional acceptance
It triggers deadlines and transfers risk. It is prepared for, with a snag list drawn up on site.
Guarantees
They are only useful to those who kept the evidence: minutes, dated photographs, correspondence.
Applicable framework
