Located on the corner of Fellows Square on the historic Trinity College campus, the Trinity Long Room Hub project comprises the construction of a new 4-storey 1,630m2 humanities research office building built directly over the single storey Edmund Burke theatre. The building is constructed using a steel frame supported off concrete cores with lightweight stone cladding facade systems.
The building is unusual in that it is constructed over the existing lecture theatre in the Arts Building (the Edmund Burke Theatre) which is a protected structure. The building had to clear span over the existing building which required a hybrid vierendeel truss on the rear elevation which was picked up on a large cantilever truss on one end. The available space on site was extremely restricted and access was also difficult and this had to be reflected in the solution adopted.
The programme was restricted in its length, resulting in lightweight and prefabricated construction being utilised where possible, but in no way compromising the design in order to provide a robust, durable and sustainable solution.
As well as working close to existing foundations and basements, a number of mature trees had to be retained in very close proximity to the building, and this required very precise foundation design, taking into account the contractors working space requirements and health & safety regulations.
