For example, buying land for real estate can save interest on investment loans. Because you can listen to the advice of CM manager when designing, you can consider the construction factors in advance and use value engineering to save investment. (3) Part of the design, part of the bidding and timely construction, so there are few design changes.

The disadvantage of this method is that sub-item bidding may lead to higher contracting cost, so it is necessary to make analysis and comparison, study the number of items of the project and choose an optimal combination point.
