Abstract: Engineers in Dublin favour founding structures on the hard interbedded limestone, which underlies the city. Despite the apparent good ground conditions, problems have been experienced on several sites. A detailed description is given of the problems encountered during ground anchorage installation at the Jervis St. shopping centre site. In all, 72% of the 443 anchorages encountered some difficulty. The pattern of zones within this site, where the difficulties were encountered, and the location of all 5 sites whereproblemshave been recorded correlates well with the known bedrock conditions in Dublin. The case histories detailed here show that the process of construction (particularly drilling technique) and the effects of groundwater need to be carefully considered when designing underground works in hard interbedded limestone. Design and construction issues cannot be separated and this calls for more collaboration between designers and contractors.
