Estimated Costs

The costs for the Alternative Integrated Option have been estimated by measuring the key components and using current unit rates.  Generous allowances have then been made for the minor items which cannot be measured in detail.

This is a common approach for arriving at an overall estimate but does not necessarily give an accurate estimate of the individual quoted items without detailed explanations of what is included in that item.

The resulting estimates, expressed in HK$Bn, are:

  Express Rail Link Hong Kong Island Express Totals
Tunnels   4 2.2 6.2
Bridge   0.8 0.8
At Grade 1 0.5 1.5
Station 4 1.5 5.5
Depot 2   2
Systems 3 5
Resumption and Compensation     1.5
Contingencies     2.5
Total     25

This estimate does not include for road improvements remote from the terminus which may be deemed to be necessary and a further $2Bn should be allowed for these possible works.

These resulting estimates have then been compared with the total project costs for other recent railway projects including the published estimates for the Express Rail Link to West Kowloon.

These projects include:

Lok Ma Chau Spur

Kowloon Southern Link

West Island Line

South Island Line

Shatin Central Line

All of these projects differ in the number and type of stations as well as the other items of non-railway work included in the projects. For example, the West Island Line includes a new swimming pool complex for Kennedy Town.  As a result a direct comparison of costs based on the length of the project is not possible. However making adjustments for the scope of the various projects confirm that the overall estimate of HK$25 for the Alternative Integrated Option is reasonable.

The best comparison is with the published estimates for the Express Rail Link to West Kowloon which is $53.7Bn for the “railworks” and a further $11.5Bn for “accessibility of terminus and neighbouring districts”.

The length of tunnels and the Rambler Channel Bridge for the Alternative Integrated Option are 13.5km in length, just over half of the 26km of tunnel for the West Kowloon Option.   The station for the Integrated Option is above ground and its cost will be less than a quarter of that for the West Kowloon Station which it is reported accounts for half of the cost of Government’s scheme.

The depot for the Integrated Option is much simpler than the combined rescue centre and depot required for the West Kowloon Option thus reflecting a cost of less than half for this element. The resumption is a fraction of that required for Choi Yuen Tsuen and other locations.

Overall the work for the Integrated Option is less half that for the West Kowloon Option giving a comparable cost for the Integrated Option of about $20Bn. The estimated cost, obtained by measuring the major items with generous allowances for the minor items, gives the estimate of $25Bn for which a further $2Bn should be allowed for road improvements remote from the station location.  This estimate is therefore considered to be reasonable.
