Evaluating the effects of a deep excavation on monumental buildings: MarmorKirken station in Copenhagen
This paper describes the Building Risk Assessment (BRA) process implemented during the design and construction of MarmorKirken metro station in Copenhagen. Being the box station very near the monumental church, the evaluation of the effects induced by the excavation on the church was a key issue of the design. Surveys, structural and geotechnical investigations were carried out to setup reliable structural and geotechnical numerical models on which BRA, at the design stage, was based. During construction works, design predictions were systematically compared with monitoring measures, allowing to update the BRA. According to BRA results, no significant effects of construction works on the church was observed.
