Abstract: In recent years, my country has developed rapidly, and the field of engineering construction has also ushered in rapid development. Construction units, survey and design units, supervision units and construction units in the field of engineering construction are gradually increasing and strengthening.In recent years, there have been discussions on supervision reform in the field of engineering construction. As an independent third party in the field of engineering construction, the supervision unit should seek reform direction from itself, improve its position in the field of engineering construction,and be respected.
