Foundation Considerations As the part of the building which is in direct contact with the ground it is necessary than when load is transmitted from the building to the foundations that any movement is limited not to adversely effect the functional requirements of the building or neighbouring buildings. Due to the sites quay location and the unknown structural integrity of the dock it is invisaged that a cofferdam may be necessary in order to form a secure basement structure - consisting of sheet piles, concrete piles & waterproof tanking sheets. There could be a potential need for pumping of water during the excavation process dependant on the condition of the existing quay.
