DELAYS in awarding the Central Reclamation project have scuppered hopes of opening the Hongkong station for the Airport Railway by June 30, 1997, according to project director Mr Russell Black. ''We are going forward on the basis that there will be a phased opening of the railway, first with the Kowloon station in 1997, and Hongkong station later,'' he said. ''The phasing delay for Hongkong station will depend on the actual start date of the reclamation.'' Mr Black said that the Hongkong station would probably open four months after the Kowloon station. The Mass Transit Railway Corporation (MTRC) received tenders last Monday on contract ''502'', for the design and construction of the MTRC's immersed tube tunnel that will cross the harbour for the Airport Railway. ''We are proceeding on tender assessment, with the objective of being in a position to award a contract in the summer,'' Mr Black said. Mr Black said all the main design consultancies for the whole of the railway had been awarded. ''Design is proceeding satisfactorily against the programme,'' he said. On the delayed Central Reclamation project, Mr Black said the corporation held two valid tenders, with the contractors extending the validity date at the request of the Government. ''The situation remains that we have two valid tenders on the table. ''The action required is for the administration to put the funding request to the Legco Finance Committee. ''The corporation is obviously keen for that work to be put in hand.'' According to Mr Black, agreements have been reached with the Government to keep the project on track. He said the Legco Finance Committee had authorised the funding to construct additional significant elements of the Airport Railway's civil works within Government contracts. These included the cut and cover tunnels from Kowloon station to Tai Kok Tsui.
