Abstract: There are some excessive factors such as caused by imperfect survey in design and construction of engineering. Taking a foundation works as example, according to the principle of“technically feasible and save investment”, as well as the geological conditions in construction site, the paper compares and selects the best solution from four feasible construction solutions by using Value Engineering, and achieves good economic benefit after practical application. It is helpful to understand and apply Value Engineering.

Key words: excessive factor; Value Engineering; foundation engineering; scheme selection
