The South Apron Extension at Dublin Airport involved the addition of four new Code C stands (3 x A321, 1x A320 which also facilitate a self-manoeuvring ATR aircraft). To facilitate the development, existing structures, equipment and infrastructure needed to be relocated to alternative locations within the airport. The project consisted of an enabling works contract implemented in advance of a main civil works contract. RPS provided multi-disciplinary design services to Dublin Airport Authority for both contracts.

A particularly challenging project element was controlling the discharge of uncontaminated surface water to the Cuckoo Stream as this stream receives the greater part of the airport drainage. The management of surface water was not only a key issue for the local community - it was an aviation safety risk for the airport. RPS carried out detailed design to ensure that all potential contaminated run off was captured and separated from surface water prior to discharge to the Cuckoo Stream.
Additional project challenges addressed included:
Enabling Works Contract
RPS provided detailed design, tender documents and contract administration services for the development of approximately 8,500m2 of concrete pavement area. This facilitated storage areas for ground service equipment relocated to support delivery of the main civil works. The design solutions we developed for the Enabling Works contract included:
Main Civil Works
RPS were appointed to prepare Outline Design, Tender Documents and Contract Administration for a Design Build Contract (FIDIC Yellow Book) to develop four new Code C stands, associated civil, mechanical and electrical infrastructure including diversion of the Cuckoo Stream. For this package of works, we prepared preliminary designs of four new stands, associated lighting, power supply, pavement surface water run-off, de-icing drainage and attenuation facilities. The surface area drained was 17,000m2 to store 1:100 AEP below ground and the capacity of the surface water attenuation tank was approximately 1,200m3.
Other services for this stage of works included:
