ABSTRACT

ABSTRACT: Little data is available in the literature on the response of heritage masonry structures to excavation-induced vibrations. This paper presents unique data and observations relating to deep rock excavations performed on Parliament Hill, Ottawa, Canada, during the summer of 1997. Some of the excavations were carried out directly beneath the 80-year old Centre Block building and some were undertaken immediately adjacent to the 150-year old Library of Parliament. The works were part of an overall scheme of renovations to renew and upgrade existing mechanical, electrical and telecommunication services within the Parliamentary complex by the construction of a new Underground Services Building. In this paper, data from an extensive array of monitoring instrumentation is evaluated and forms the basis for determining building response characteristics and attenuation rates (decoupling) at the rock-foundation interface.
