|Bewleys Hotel, Dublin|
This development involved the conversion of the 19th Century Thomas Prior House School buildings into a 12,000m2 300 bed apart-hotel. The existing buildings date back to the last century and are built in High Victorian style. The original facades are Grade 2 listed and needed to be retained and incorporated into the new development.
TPE Consulting Engineers Services
In addition to retaining the facades, this project provide a number of other challenges to TPE Consulting Engineers, perhaps the biggest was the issue of buildability. The basement plan area covers approximately 80% of the site which applied significant limitations to the main contractor, and meant that a very close working relationship needed to be developed with main contractor from the start of the project.
The new structure involved contiguous piling to form the two levels of basement. Piled retaining structures were also installed around the existing foundations of the retained facades. The existing ground below and around the footings was then pressure grouted to prevent settlement and minimise the risk of damage to the existing facades during the excavation of the basement levels. The two basement levels were constructed using flat slabs supported by RC columns with a transfer slab at ground floor level supporting the load bearing block work and precast flooring structure for the six floors of over 300 rooms above. The new structure was tied into the existing façade at each floor level which led to many challenges when trying to match the new structure with existing.
The blend of old and new has been very successful on this project such that a new modern interior is complimented by the timeless exterior of the original building.
