Abstract
Starting from concrete situations encountered in the city of Iasi,Romania, are presented the methods used by the authors to assess the siting of new construction in urban areas, densely built. The results are compared with measurements made to support deep excavation and settlements for new buildings and those are in the zone of influence them. Proposals are to regulate the obligations of owners to ensure a minimum strength and stability of existing buildings and acceptable limits must fall within which design a new structure.

Highlights
Density urban growth leads to the need to build tall buildings with deep foundations, positioning the car parks and other facilities in their basements
There are numerous sources of risk associated with performing deep excavations in urban areas, sources which must be considered in the design and execution of these works for any additional costs to a minimum
To reduce the risk of failure of deep excavations and damage to adjacent buildings support design work should be done through detailed analysis of deformation and verification by several methodsempirical and simple analytical
Summary
Density urban growth leads to the need to build tall buildings with deep foundations, positioning the car parks and other facilities in their basements. With the increasing trend of the depth of the foundation of these buildings is highlighted and the need to work to support the earth, larger and more rigid. This trend is reinforced by the need for founding the less compressible soil layers and the desire to create spaces to facilitate positioning of underground utilities and underground parking. There are numerous sources of risk (hazards) associated with performing deep excavations in urban areas, sources which must be considered in the design and execution of these works for any additional costs to a minimum.
