7 Hanover Quay

€20 million
A €20M development consisting of 5,700 sqm of commercial and residential space at Hanover Quay, Dublin.


The office building is 6-storey over basement and the residential buildings comprise 2 buildings in apartment type layout, 7 storeys over basement. The development was originally constructed on reclaimed land which was contaminated. This required a 1 year programme of careful removal of the excavated material to a designated site.


Because of the location of the development in close proximity to the river Liffey, the basement construction consisted of the provision of a secant piled wall to the perimeter and the provision of back props to the top of the external wall system. The foundations to the development were 600mm dia. bored piles throughout.


The superstructure was formed with a reinforced concrete columns, core walls and flat slabs to both the residential and office development with glazed screens externally.


This development is on a confined city-centre quayside site, and DBFL’s civil and transportation engineers were involved from a very early stage to ensure all design and access issues were addressed early on in the project.  DBFL were involved in all stages of this project from initial concept design, through planning and throughout the full construction period.


In 2014 DBFL were subsequently appointed by IPUT on the refurbishment of this development. The main structural challenge in this refurbishment of the existing 7-storey office building involved a dramatic upgrading of the main entrance by cutting back the existing first floor slab to create double height support columns each side of the entrance. DBFL devised a solution that minimised the amount of temporary propping required to enable to work to be carried out.


Other works included a new entrance canopy, new plant support steelwork at roof level and modifications to the load-bearing structure in the basement.
