We, daa plc intend to seek planning permission for development on 4no. sites located entirely within lands in the ownership of Dublin Airport, including 2no. sites at the Airfield in the townlands of Collinstown, Coultry, and Huntstown, Co. Dublin, 1no. of which incorporates part of Pier 3 and surrounding aircraft stands, aircraft stands to the south of Pier 2, Apron Taxiway 4, Taxiway F-2, Runway 16/34 (the crosswind runway), Taxiway W1 and W2, West Apron; and 1no. of which incorporates an existing airside site compound, south of the West Apron; 1no. area of land to the west of the existing Western Compound, south of the R108, north-west of the Airport, in the townland of Pickardstown, Co. Dublin, also to be known as the Western Compound; and 1no. an area of existing hardstanding to the south-west of the Airport, north of the R108, to be known as the Southern Compound, in the townland of Portmellick, Co. Dublin. The proposed development will consist of the construction of a subterranean Underpass of Runway 16/34, a critical airfield operational safety project, which will comprise: a) A twin-cell enclosed tunnel with 2 no. lanes in each direction, linked to the surface by ramps, portals, and light attenuation screen (1.8m in height above existing ground level at the west ramp and 3.3m in height above existing ground level at the east ramp). The enclosed section will be approximately 0.7 km long, with an overall alignment of approximately 1.1 km in length from top of ramp to top of ramp. It will be approximately 24m in external width, and approximately 5.5m in internal height from road to tunnel ceiling. It will be up to 17.5m below existing ground level; b) Plant room, of approximately 625m2, which will comprise housing for transformers, pumps, controls and communications equipment, located underground at the portal of the east ramp, a parking layby and utilities corridor crossing; c) Demolition (approximately 23,741m2) and reinstatement (approximately 16,216m2) of part of the pavement surfaces of Apron Taxiway 4, Taxiway F-2, Runway 16/34 (the crosswind runway), Taxiway W1 and W2, and the West Apron; d) Access roads to tie in with the existing airside road network at each end of the proposed Underpass (at Pier 3 on the Eastern Campus and the West Apron on the Western campus respectively), and 31no. car parking spaces at surface level at Pier 3; e) Demolition (approximately 97m2) of fixed links (elevated enclosed passenger walkways leading from the Pier to Aircraft Nodes) and Nodes (structures which provide support for the fixed links and internal pedestrian access cores to ground level) serving 3 no. aircraft stands and associated airbridges (passenger boarding bridges) at Level 20 (departure gates) of Pier 3. To the south of Pier 3, an existing airbridge is to be removed and an existing fixed link is to be adjusted to service existing stands in that area; f) Replacement of the demolished fixed links and nodes with 3no. new fixed links, A (approximately 356m2), B (approximately 227m2) and C (approximately 170m2) and of approximately 150m, 95m and 70m in length respectively and approximately 2.2m in width and approximately 3.2m in height, at a maximum height of approximately 7.1m above the surrounding apron; 3no. two-storey Nodes A, B and C, approximately 157m2, 154m2 and 148m2 in area respectively; and 2 no. airbridges (1no. at Node A and 1no. at Node B). g) Modifications to the elevations of Pier 3 at Level 20 to accommodate the links and airbridges, including part replacement of the existing glazing with new glazing/cladding, and a new cladded portal with new doors and access control at each new fixed link location; rearrangement of part of the internal floorspace of Level 20, including a new partition between the entrance/ exits of proposed fixed links A and B; new surface water drainage network; and 31no. car parking spaces at surface level; h) Realignment of stands on the Eastern Campus resulting in the net loss of three Narrow Body Enabled (NBE) stands and net gain of one Wide Body (WB) stand at Pier 3; i) Realignment of aircraft stands in the West Apron (involving rearranging /relocating stands by way of new paint markings on the apron pavement) to accommodate the portal and Underpass access roads (no net change in number of stands); j) Modifications to existing drainage network in the vicinity of the proposed Underpass including replacement of existing attenuation system, and construction of a new drainage network for the proposed Underpass, including sump pit with pumps, interceptors, and new attenuation tank; k) Temporary diversion of the Airfield Trunk Culvert during construction and its reinstatement at the existing alignment and level; I) Construction of a new underground pipe network (6no. new pipes) to allow for future drainage infrastructure/surface water management measures; m) Realignment of stands at Pier 2 on the Eastern Campus (no net change in number of stands); n) All ancillary airport infrastructure including additional apparatus/equipment including jet blast fencing, Fixed Electrical Ground Power (FEGP), Advanced Visual Docking Guidance System (AVDGS), Stand Number Indicator Board (SNIB), Fuel Hydrants, High Mast Lighting (HML), electrical charging facilities, and miscellaneous ground service equipment (GSE) parking and storage areas; o) The proposed development also includes (i) a new Western Compound adjacent to the existing Western Compound located south of the R108, north­ west of the Airport, with a new access off the R108, to be used for pre-screening for deliveries going airside, and to include an airside pass office, parking for construction staff, as well as storage areas, and general logistics; (ii) the provision of a new Southern Compound to the north of the R108, to the south west of the Airport, to be utilised as a lorry waiting area for HGVs. No works are required at this Southern Compound; and (iii) the use of an existing airside site compound adjacent to the proposed Underpass, south of the West Apron, for concrete crushing, batching plant, the storage of non-hazardous materials and equipment, as well as offices, workshop, welfare facilities, and parking. The proposed development does not propose any increase in passenger, cargo or operational capacity at Dublin Airport.
