The main differences in the ACP costs as at July 1991 and those shown in this
paper are accounted for as follows -
(a)
Projects funded by Government
(1) North Lantau Expressway The increase of $990 million is mainly due to the
T
inclusion of the cost of the utility reserves to cross three existing high voitage
submarine cables ($121 million, inclusion of the cost of forming a site at Tai Ho for
millor
the construction of the AR depot ($424 million)", constructing some railway structures
as part of the expressway works ($155 million)* and inclusion of an access bridge for
the Airport Railway between Tung Chung and Chek Lap Kok ($118 million)".
-
(ii) Route 3 The main reason for the increase is the allowance for shared and
adjacent viaduct structures for the Airport Railway in Kwai Chung ($363 million)".
(iii) West Kowloon Reclamation (WKR) - The increase is mainly due to increase in
reprovisioning and land compensation costs ($477 million), additional requirements
for hinterland drainage and new roads and drains ($344 million), higher than
anticipated cost of removing contaminated mud ($105 million), improving the
standards of facilities at the Cheung Sha Wan Wholesale Markets which are to be
reprovisioned for the WKR ($240 million) and adjustment to the project contingency
allowance.
(iv) Utilities and Others - The increase is partly due to raising the project contingency
allowance for water works projects to a more prudent level ($180 million), and partly
to the inclusion of other facilities such as the Lok On Pai Transhipment Centre ($50
million) and services such as fill management studies ($67 million), project
management consultancies ($209 million) and Owner-controlled Insurance Programme
($280 million).
Note: Items marked with * are AR works which will be reimbursed by the MTRC. They have been included in the overall AR cost of $22.16 billion and there is no double counting.
