1 Future Development of HKIA Planning of the Three-Runway System Presentation to Hong Kong Air Cargo Forum 19 June

2 Three-runway System: A Three-phase Process Planning Approval Implementation Environmental Impact Assessment studies Associated design details Funding options Environmental permit Foreshore and seabed gazettal Financial arrangement Land formation Detailed designs Construction of related facilities About 2 years* About 1 year* About 8 years* *Indicative timeline that is subject to changes 2

3 EIA & Planning Study Team EIA Lead Consultant Mott MacDonald EIA Review Consultant ERM Air Quality Consultant Arup Aircraft Noise Consultant URS 3 rd Runway Infrastructure & Concourse Scheme Design Consultant Mott MacDonald AAHK 3 rd Runway Reclamation Scheme Design Consultant Atkins Chinese White Dolphin Experts Bernd Wursig & Tom Jefferson Terminal 2 Expansion Scheme Design Consultant AECOM 3

4 EIA Calendar Submit EIA Report to EPD end 2013 EPD to review and approve EIA 2Q 2014 Obtain Environmental Permit 2Q

5 Three-Runway System EIA Study Brief 1st EIA for a Transport Infrastructure Project to require consideration of health impacts (aircraft noise/ emissions) Covering 12 environmental aspects: Air Quality Noise Hazard to Life (Fuel System) Water Quality Sewerage and Sewage Treatment Waste Management Land Contamination Chinese White Dolphins Marine Ecology & Fisheries Landscape and Visual Cultural Heritage Health Impact (Aircraft Noise/Emission) noise/emission) 5

6 Scheme Designs to Complete in 2Q Reclamation Completed 2. Terminal 2 Expansion In progress 3. 3 rd Runway Infrastructure/Concourse In progress Detailed Designs to follow (planned to take 2 years) 6 6

7 Reclamation Works Future 3 rd Runway to be in operation by Q (existing North Runway closed) Airside Fire Station 7

8 Key Technical Challenges & Constraints Environment Related Existing Airport Not subject to EIA 3RS Reclamation on Contaminated Mud Pits; No dredging committed Fill Source Locally available Need to secure marine sand from the Mainland Land Formed Airport Operation Integration of Facilities Some superstructure built on rock platform Built on green field site No planning on site needed Construction on reclaimed land Works subject to airport height/operational restrictions Need for closure of North Runway 8

9 Key Challenges & Constraints Non-dredge Seawall Foundation Soft marine clay outside CMPs Seawall Implications -> Require Special Ground Improvement 9

10 Key Challenges & Constraints - No Locally Available Fill Sources East Sha Chau Brothers Borrow Area Main Sources for Existing Airport Original CLK Island, Lam Chau & Brothers Islands Quantity ~120 Mm 3 South of Tsing Yi West of Po Toi Brothers Borrow Area ~30 Mm 3 East Sha Chau ~15 Mm 3 West of Po Toi ~15 Mm 3 South of Tsing Yi ~10 Mm 3 Implication -> Require to search for fill sources outside HK 10

11 Key Challenges & Constraint - Construction on reclaimed land Existing Airport 3RS Footprint of Reclamation Existing Reclamation 983 Ha Original CLK Island 258 Ha Lam Chau 7 Ha Existing Airport 3RS ~983 ha Reclamation Area ~644 ha ~11 km Length of Seawall ~13 km ~190 Mm 3 Total Volume of Fill Required ~130 Mm 3 ~70/0/120 Mm 3 Sand Fill/Public Fill/Rock Fill ~110/10/10 Mm 3 11

12 Key Challenges & Constraints Airport Height Restriction 53 AHR due to Sha Chau Radar Implications of radar removal -> Remove constraints on the size of marine construction plant over most of the reclamation area 12

13 Key Challenges & Constraints Need for closure of North Runway 3 rd Runway and Taxiways (2021) New Airfield Tunnels New Concourse New Taxiways Closure of North Runway (2021) Re-open of North Runway (2023) 13

14 Ground Improvement Steel Cells Deep Cement Mixing (DCM) Deep Cement Mixing(DCM) Stone Columns Prefabricated Vertical Drains (PVD) Low Headroom DCM Low-headroom DCM 14

15 Reclamation Works Construction Sequence Sea Water Level Surcharge Land Fill Sea wall Marine Fill Sand Blanket Contaminated Mud Pit / Marine Deposit DCM PVD DCM N.T.S Seawall Zone Formation Zone with PVD Formation Zone with DCM 15

16 Seawalls: Steel Cells Installation Approach for HZMB Islands in PRC waters (No AHR Constraint) AHR-adapted Installation Approach for Steel Cells Cofferdam 16 16

17 Target Baseline Programme 4 Year Reclamation Programme 2 Years (24 Months) 2.5 Years (30 Months) 3 Years (36 Months) 3.5 Years (42 Months) 4 Years (48 Months) 17

18 Scheme Design T2 Expansion Design Goals What is the most sustainable, long-term approach to the providing an expanded Terminal 2, as part of a 3-runway system? How do we match the very high standard set by Terminal 1 to ensure HKIA provides a consistent Level of Service? 18

19 Scheme Design T2 Expansion 19

20 Scheme Design T2 Expansion Evaluation of Differentiators Level of Service/ Pax Experience Operational Efficiency Commercial Environmental Quality/Image Walking distance, level changes, wayfinding, special features Capacity, impact on existing operations, economy of resources, flexibility Retail, advertising, commercial development (including NCD) Energy efficiency, BEAM + rating, green perception Architecture, spatial quality, quality of building systems 20

21 Scheme Design - 3 rd Runway Infrastructure and Concourse Key Planning Parameters being Studied Strategy for Automated People Mover Strategy for Baggage Handling System Concourse and Apron Layouts 21

22 Estimated Project Cost Master Plan $ 86.2 bn MOD bn 22

23 3RS Programme Update Obtain Environmental Permit 2Q 2014 Obtain ExCo s project approval 3Q 2014 Complete statutory processes 1Q 2015 Complete detailed design and obtain LegCo s funding approval By end 2015 Start reclamation 1Q
