Clayton Hotel Cardiff Lane Conference Centre, Dublin

Ground-breaking set-up sees energy-efficient heating and cooling AHUs operating in tandem with hybrid VRF air conditioning system...

Clayton Hotel’s new five-star Meeting and Events Centre, located at its Cardiff Lane venue in the heart of Dublin city, is equipped with state-of-the-art infrastructure and facilities.

Kerrigan Mechanical, in partnership with main contractor Monami Construction, was tasked by Dalata Hotel Group with providing the full mechanical installation for the conference facility, as designed by Patrick McCaul Environmental Consulting Engineers.

Architects Douglas Wallace created a split-level complex by incorporating a new mezzanine floor. With a capacity for up to 220 people, the new centre boasts three meeting rooms in the lower ground floor (below street level), while the upper ground floor incorporates a large conference space, which can be split into three smaller rooms if required.

Impressively, Kerrigan successfully installed a uniquely innovative and energy-efficient system, making this facility the first of its kind in Ireland.

The work included heat recovery AHUs and a highly sophisticated hybrid VRF air conditioning system. While these two systems would normally be separate, they now operate hand in hand to achieve maximum energy efficiency.

Such a complex set-up, which was a client requirement, needed detailed accurate BIM modelling from the highly-skilled team at Kerrigan.

Francis McNulty, Contracts Director at Kerrigan Mechanical, said: “This approach ensured we could provide a system that would firstly fit in such a compact space and secondly perform beyond best expectations. It was certainly a challenge, but one we are proud to have overcome.”

As with any project of this size, there were more than a few hurdles to overcome for the team at Kerrigan.

With the void space being heavily congested by ducts, pipes and air conditioning, the company decided to use BIM to model all the plantrooms in a bid to utilise the limited space available to its fullest potential. 

And of course, Covid-19 restrictions slowed down the construction process, as it cut the number of people who could work on any aspect of a project at any one time. Despite these curbs, Kerrigan still managed to complete the work as scheduled, on time and within budget.

But perhaps the most critical challenge presented was the removal of the existing gas line. Kerrigan installed a temporary gas supply running along the exterior of the building, before removing the existing 4” line and replacing it with an upsized 6” pipe.

“We had two extremely successful changeovers and were delighted to record minimum downtime of an hour for the second, which was to the client’s delight,” Francis added.

“There was minimal disruption to the live hotel operations, which remained fully active and functioning for the duration of the works. Following handover, we took great pleasure in hearing that the hotel was at over 90% capacity for the majority of the time, and there were no complaints regarding any disruption.

“We were delighted to be involved in such a high-profile project in the centre of Dublin. We have strong relationships with Dalata, Monami, Patrick Mc Cauls and Douglas Wallace and we look forward to working with them on other projects of similar scope in future.”
