Distillery site in Smithfield Village. The project was also a formative project for Ciarán Kennedy, our current Managing Director, where he acted as Graduate Engineer working in a design office set up on site for the duration of the project.

Our first significant project as Main Consultants was Smithfield Village with Client Heritage Properties. This was an early ‘Celtic Tiger’ project involving the redevelopment of the old Jameson

New recruits in the early days were John Considine, Ciarán Kennedy and Ed Carthy who gave us much needed highly skilled Technical Resources to bid for more ambitious projects.

Our first client was Hegarty Demolition who was heavily involved in the reconstruction of Temple Bar at that time and our fi rst major job was the Façade retention of Switzers, now Brown Thomas department store.

2000’s

Around this time, we also began our involvement with client John Fleming.

The early noughties, with the Celtic Tiger in full flight, brought significant growth to the practice and by 2006 we had leased additional space nearby on Pearse St and staff numbers had grown to circa 100.

London Office opened with Vincent Barrett as Managing Director. This was our lifeline during the depths of the recession and the sterling work put in by Vincent saw the London Practice grow to become a significant client of the Dublin Office.

The last number of years have seen rapid growth under Ciarán Kennedy’s management and we now look forward confidently to the 2020s with a “Blue Chip” Client base and exceptionally gifted staff resources numbering circa 70 in Dublin, 20 in London and 10 in Sofia.

2016 also saw the setting up of our Sofi a Office by Rouslan Taskov. Rouslan had worked for Barrett Mahony for many years, firstly for the Dublin Office and then for the London

In 2007 the chill winds of recession began to be felt and over the next two years many of our Developer Clients were hit

2016 saw a significant upturn in our workload and marked the stepping back of the founding Directors from frontline management and the appointment of a new Managing Director, Ciarán Kennedy, to the Dublin Office along with another new Director Stephen O’Connor who joined the board alongside existing Board members John Considine, Vincent Barrett and Brian Mahony.

Significant other projects in the late 1990s were AIG HQ on North Wall Quay, the Clarion Quay development, also on the North Wall, and the Microsoft Building in Sandyford.

Recession strikes Ireland and the oil price drops in the Middle East leaving ICDS without work, both Vincent and Brian move to London to work in the London offi ce of Irish Consultancy, KML.
