6 OPTION 2: THREE-RUNWAY SYSTEM Figure 6.2 Option 2 – Airport Layout Plan in 2030 have been developed by AECOM for airport facilities planning. This is to ensure that the different permutations of the location of the passenger processing terminal, passenger concourses, and aircraft parking aprons required to support the third runway have been fully evaluated before recommending the most suitable airport layout. The 18 airport layout options have been evaluated against the following five major criteria – (a) Airfield efficiency; (b) Passenger convenience; (c) Cargo operations efficiency; (d) Surface access; and (e) Environmental impact. The final recommended airport layout features a northward expansion as illustrated in Figure 6.2. (at money-of-the-day [MOD] prices)11, including provisions for design, project management and contingency, and phased over 15 years between 2016 and 203012 as follows – (a) Land formation (HK$38.9 billion) • reclaim about 650 hectares of land north of the existing airport island (b) Third runway, related taxiway systems and airfield facilities (HK$7.5 billion) • construct the third runway • construct a dual parallel taxiway and connect taxiways to the passenger concourses and apron areas CAPITAL INVESTMENT On the basis of the final recommended airport layout, our consultants have worked out the necessary airport infrastructure that fully utilises the maximum runway capacity (620,000 ATMs/year) and its costing. They have recommended an estimated capital investment of approximately HK$86.2 billion (in 2010 dollars) or HK$136.2 billion 11 The final construction cost of the capital projects will be increased from the current estimate based on 2010 dollars to the MOD amounts, in line with the Tender Price Index (TPI) which is estimated to increase at the rate of 5% per annum from 2011 to 2014, 5.5% per annum from 2015 to 2020 and 3% per annum thereafter. The cost breakdown is in 2010 dollars. 12 34
