Controlling the altering engineering that means to control the cost of engineering basically.

The application & practice of management in systematic procedural project changes;

Contract management of project changes of Shuiyu reservoir s danger removing and strengthening work;

The influencing of project changes in cost management;

On the management of the engineering change based on the engineering quantity list valuation mode;

How to deal with the accounts settling of engineering changed items by chartered estimation engineers;

Discussion on the method of supervision engineer treating engineering change;

Reflection on claims from engineering alteration;

Combined with engineering practice, the supervision experience in the implementation of FIDIC clause in Handan water supply project was introduced in aspects of payment of engineering fees, disposal method of engineering alteration, and claim for compensation.

In this paper,how to determine alteration unit price is explored by analyzing the causes of engineering alteration and adjustment of engineering amount.

Importance of project changes in project settlement;

The contents application and endorsement process of project changes;

According to the property of project variation,the paper divides variation into fatal variation,important variation and general variation,and points out that we can control variation effectively by establishing.

To strengthen the active control of architectural engineering construction cost,and reduces the project variation visa during the project construction stage as far as possible,and guarantee the project settlement price does not surpass the investment plan volume which confirmed,and speed up the rate of project settlement progress.
