McAvoy completes offsite construction of new passenger facility at Dublin Airport

South Gates terminal at Dublin Airport, completed by the McAvoy Group

DUNGANNON-headquartered McAvoy Group has handed over a new passenger facility at Dublin Airport which was built offsite - and which at more than 19 metres wide is believed to be the largest single span modular building delivered in the UK or Ireland.

The new €22 million South Gates passenger boarding area has been developed to meet the huge growth in passenger numbers at Dublin Airport and will be used mainly by Aer Lingus for flights to the UK and continental Europe.

It provides seven boarding gates to serve nine aircraft stands and is designed to accommodate around 8,000 passengers a day.

The management contractor for the project was Flynn Management & Contractors and the lead consultants were Arup. The building was designed by concept architects Kavanagh Tuite and delivered by project architects Blue Sky.

The 2,200 square metres facility was constructed offsite at the McAvoy production centre in Lisburn to reduce time on site.

It was craned into position in just 16 days as 77 steel-framed modules. The building system was engineered to achieve over 19m wide uninterrupted clear spans, which is believed to be an industry first for modular construction.

The building, which is around 120m long, has the flexibility to accommodate departing flights in the busy early morning period and flight arrivals in the evening.

It can also be segregated so around 1,000 departing and arriving passengers can be processed at the same time. Facilities include boarding gates, a café, toilets, baby changing and a workstation area with plugs and charging points.

Eugene Lynch, managing director of the McAvoy Group, said: “This project successfully demonstrates the potential for offsite to improve the efficiency of airport construction, particularly in the development of airside facilities where it is so critical to minimise any impact on existing operations.

"We can reduce work on highly secure and constrained sites and rapidly instal the buildings in a fast and efficient process, with no compromise on design.”

Dublin Airport has experienced a six per cent increase in passenger numbers in the past year and a record 29.6 million passengers used the airport in the last year.

Iain Heath, project manager at Dublin Airport, said: “This is one of the fastest projects we have ever completed at the airport – from planning to the first flight in just 18 months. The finished building speaks for itself. It is a handsome new facility with high quality finishes and clean architectural lines.

“We were working to a very constrained programme to have the building operational ahead of the busy summer season. The project and its innovative use of offsite construction is a fantastic achievement for the whole team. This approach had far less operational impact for the airport and the closure of fewer aircraft stands with reduced time frames.”

Brian Looney, contracts manager at Flynn Management & Contractors said: “The principal driver for offsite construction was to reduce the programme. The McAvoy solution allowed the building to be delivered to site within weeks of planning approval.

"Having fewer trades on site is also a benefit for airport projects such as this where the site is very constrained, and the highest standards of security have to be maintained at all times.”

“This project has pushed the boundaries of offsite construction to create a valuable infrastructure facility. The quality of the finished building is excellent, and you would never know this is a modular building. The McAvoy Group's production facilities are impressive, and their systems are robust. We would welcome the opportunity to work with their team again.”
