Construction of a new building (NB) affects existing adjacent old buildings (OB) during pit excavation, piling, footing and NB erection. Two relevant history cases are described. In the first one, the graphs of OB settlements versus distance from the pit are given for the period of pit excavation and the total settlements for the period of NB erection. The second case gives the family of OB settlement time-related graphs versus distance from the pit, in which these settlements were caused by piling operations
