Under the EPC (design procurement construction general contracting) mode, there is a significant difference between the treatment of missing items or missing items in the bill of quantities and the traditional construction general contracting mode.

The following are the core principles and processes for dealing with such problems: 1. The division of responsibilities is based on the fixed price contract agreed in the contract terms: if the contract specifies that the bill of quantities is "reference" ... View details
