Dublin Airport Terminal 1 Extension

RPS was appointed by the Dublin Airport Authority to carry out the management, design development and contract administration of the Terminal 1 Extension at Dublin Airport.

The airside terminal extension is designed to improve passenger circulation space and comfort in the terminal areas and consists of arrivals and departures facilities on two levels plus a mezzanine. There is also ancillary support accommodation including additional check-in areas with baggage facilities, retail and restaurant/bars on the mezzanine level.

The project had an aggressive fast track programme driven by the challenging aspirations of the DAA management to open the new facility in mid 2009 to meet dramatic increases in passenger numbers. It is expected that continued growth in passenger numbers, exceeding more 22 million, will use the terminal in 2008.  In facilitating this process RPS managed a two stage Design - Manage - Construct procurement route specifically adapted to the Irish market conditions.

RPS was responsible for the development from inception through to outline design, planning submission, tender documents, overseeing the detailed design and construction supervision.

The services provided included design development and value engineering input from inception to outline design, planning, tender and construction administration and construction supervision. 

Our design solution involved 1100 tonne structural steel frames supported on concrete foundations, fritted glazed façade and utility services management for the airside compound.

Our design concept successfully maximised off-site fabrication and construction minimising impacts on airside operations with delivery of completed structures at carefully controlled timeframes.  The floor area of 7,500m2 represents a sizeable extension to an existing public facility, with emphasis on quality and durable finishes and low life cycle costs and maintenance.

Construction logistics was a key consideration in the design process, with a critical success factor being the minimisation of disruption to the millions of passengers using the Terminal building, and the continuous and safe operations of airside workers and aircraft at the busy airport. 

There was significant stakeholder consultation necessary with a stakeholder plan successfully implemented under our leadership.   

The project was completed ahead of schedule and the terminal was opening in April 2009.
