The Exchange
Situated in the heart of Dublin’s Financial Business District (The
IFSC), The Exchange is a modern commercial building and is one of the rst new-build commercial buildings in Ireland to target LEED Gold and an A3 Energy Rating.
This €30m building contract was negotiated in November 2015 with Cosgrave Commercial Developments Ltd, started in January 2016 and scheduled for completion at the end of September 2017, a short 21 months later.
The project includes the construction of a six-storey over basement of ce block, with a gross area of 14,200m2, including a 1,900m2 basement. The structure is reinforced concrete and the design is based around a 9m x 9m grid with at-slab construction allowing the greatest exibility for tenant t-outs.
The project was initially awarded to include CAT A t-outs to all oors, but with differing future tenant requirements, we are now doing full CAT A to two oors, shell and core only to three oors and a full turn-key t out to the rst oor. The plant is largely on the roof, with the basement used for parking (37 cars and 133 bicycles) and shower facilities.
This project is the rst project in Ireland to be registered with the Considerate Constructors Scheme. The constraints of the site, the restrictions imposed by interested third parties (Planning, City Council, IFCS, LUAS) and our Considerate Constructor have de ned our approach to planning and executing the project at every turn. The site is bounded by narrow inner
city roads to the north, east and west (including the LUAS red line 4m from our northern site boundary), and a ve-storey commercial building abutting our site to the south. Our immediate neighbours are both commercial and residential.
The facades are stone (Iberian Silver Granite) and curtain walling. As is typical of city centre sites, the façades are brought right out to the boundaries on all sides. A full height glazed atrium (15m x 7m) brings natural daylight into the middle of each oor plate and to the reception area on the ground oor.
The construction of our “shallow” basement involved excavations as deep as seven metres around the site without secant piling, prompting a bespoke engineered solution to construction and shoring the basement. The speed of construction was planned and dictated by the single tower crane (sited in the atrium) and the small loading bay we were able to negotiate with the city council by hiring four parking bays on Commons Street, affording us a secure concreting / loading bay within our hoarding.
The site team consists of
Pat McArdle (Site Manager),
Aaron Murtagh (Asst. Contracts Manager),
Trevor Knott (Finishing Foreman), Ross Tiernan (Site Engineer),
Noel McDermott (Building Services), Sean McBreen (Safety Manager), Rory Kilfeather (Snr Qs),
John Dignam (Project QS), Ryan Higgins (Asst QS),
Ken Lynch (Contracts Manager) Donal McCarthy (Regional Director)
Now, with less than three months to go, the crane is gone, the façades are largely completed and it’s all hands to the wheel as we push on with the internal nishes
- the Pareto principle proved once again, with the last 20% taking
80% of our efforts!
