Abstract

An extensive low-rise hospital development has taken place since 1982 on a former opencast coal mining site 30 years after working and restoration. The clay and shale fill some 20 metres deep was placed without systematic compaction. Five separate site investigations have been carried out at different times during the last 20 years and a detailed engineering geological mapping exercise was completed in 1977. Drainage works and the main buildings in Scheme 1 and 2 have been monitored during and after construction. Significant settlements have occurred requiring some remedial work. A surcharge and inundation trial has been undertaken prior to the design and construction of Scheme 3. The response of the buildings and the drainage to ground movement is described and design recommendations made for future development.

A Low Rise Hospital Development on Restored Opencast Fill

An extensive low-rise hospital development has taken place since 1982 on a former opencast coal mining site 30 years after working and restoration. The clay and shale fill some 20 metres deep was placed without systematic compaction. Five separate site investigations have been carried out at different times during the last 20 years and a detailed engineering geological mapping exercise was completed in 1977. Drainage works and the main buildings in Scheme 1 and 2 have been monitored during and after construction. Significant settlements have occurred requiring some remedial work. A surcharge and inundation trial has been undertaken prior to the design and construction of Scheme 3. The response of the buildings and the drainage to ground movement is described and design recommendations made for future development.
