Client: Dublin Port Company
DBFL provided a technical support role to the Project Manager under an NEC contract, and coordinated the Cat III structural assessment of the design proposals on behalf of Dublin Port Company. DBFL also provided site inspection services throughout the construction phase in support of the project management team.
Berths 26/27 (Cross Berth Quay) forms part of the overall Alexandra Basin Regeneration (ABR) Project. The project was procured using a design and build contract form, and consists of a new steel combi retaining and anchor wall with reinforced concrete capping beam and heavy duty surface pavements. The new quay wall also included the construction of three new bank seats to house linkspans for the management of roll-on / roll-off (RoRo) cargo vessels. Mooring bollards, ladders and support infrastructure also formed part of the works.
This quayside project was unusual in that all of the piling works were land based, and so the use of temporary piling gates and casings allowed for relatively quick installation of 1420mm x 28mm diameter combi wall tubular piles and intermediate AZ18 S355 sheet piles.
In terms of maintenance, it was important for considerations such as design life, corrosion and general ongoing maintenance of the facility to be considered in design to form a project that would work for all. The incorporation of a cathodic protection system three years into the design life resulted in the pile thickness being optimised, which resulted in material savings.
