Because of locating adjacent to the other buildings so the construction site is narrow.Because of the narrow construction site and other factors the foundation of construction engineering was needed to be buried shallower than the original foundation which was sit in the plain fill.This needed to ground treatment with plain conerete pile.The authors reduced settlement and uneven settlement of extension engineering by reducing the base additional stress improving the ground bearing capacity of posite foundation and other measures which achieved good results.Construction engineering designers need to fully understand the original building conditions and consider the feasibility of design and construction. Key words:additional en...
