The contracts for the remaining civil engineering works down Nathan Road, the immersed tube under the harbour and the stations and tunnels in Central which were let in March 1976, made further substantial progress during 1977. In the station areas in Nathan Road and Central, that part of the construction which causes the greatest inconvenience to pedestrians and shopkeepers, the putting down of the station walls, is nearing completion and the next following process, that of excavation between the walls has already commenced.

The first 4 of the 14 sections of the immersed tube under the harbour are now in position and the next 4 sections have been completed in the drydock at Chaiwan specially built for this

purpose, and are now in the process of being

positioned on the harbour bed. This particular

contract, critical to completion of the Railway

was some five months late at the beginning of the year but by the end of the year had recovered the time lost and is now back on schedule.

Again the civil engineering contracts in Nathan Road and on the Island have not been without their difficulties. The contract for Argyle Station has gone slowly and is the subject of a dispute on a point of interpretation which could result in court proceedings. Following the adoption of

revised construction methods, however, which concentrated on progressing the track levels of the station, the opening date for these sections of the line, March 1980, should not be affected

although there is the possibility that Argyle Station itself will not be fully completed by that time.

It has to be emphasised that civil engineering difficulties of this nature are normal in the varied ground conditions that obtain in Hong Kong.

Indeed, the Corporation has been fortunate in that relatively few delays have resulted from such difficulties.

Altogether, therefore, a year of substantial

progress in civil engineering construction where

all the main contractors concerned have

continued to demonstrate their ability to over-

come the problems typical of a project of this size and complexity.

All the electrical and mechanical contracts being

carried out in the United Kingdom, Germany, Japan and the United States have gone well and

are on time. In the United Kingdom, the first two

rail cars have successfully completed manufac- turers' tests at the Tyne & Wear test track in northern England and the next 4 cars are approaching completion in the works of Metro- Cammell in Birmingham. The first 2 cars to be

計劃遲誤約六個月,因而阻延隨後之支柱及 其支承之平台建築合約。儘管如此,該打樁 合約現已完竣;總面積達25英畝之平台亦約 有五分之一已建成。在平台上興建之地下鐵 路公司行政大樓,已在順利施工中,而平台 上之第一座住宅樓宇,亦將動工興建。九龍 灣工程早期之延誤,對地下鐵路之預定通車 日期應無影响。

如上指出,九龍灣車廠以及由九龍灣至 彩虹站一段隧道內之鋪軌工程業已動工,爲 一九七八年鐵路車卡運抵本港並開始試車作 好準備。

於一九七六年三月批出之土木工程合約 ,包括彌敦道一段、海底隧道以及中環各車 站與隧道工程等合約,在一九七七年間亦有 良好進展。在彌敦道及中環各車站施工區內 ,最使行人及商戶感到不便之車站建造工 程正接近完竣,在車站之間進行挖掘之下 一步工作,亦已開始。

十四節海底隧道沉管中之最初四節,現 已沉放在海底應有的位置上,另外四節則已 在特别建造之柴灣旱塢內製成,現正被放置 在海床上。此項對完成地下鐵路工程關係至 鉅之合約,年初時阻延約五月之久,但年底 時已彌補所失去時間,現已再度納入原定之 施工進度之內。

彌敦道及港島方面之土木工程合約並 非毫無阻滯。旺角站合約進展緩慢,並由於 一個有關合約解釋方面之爭論,可能訴諸法 庭。但在採納修訂之施工方法,將工作集中 於車站路軌所在之樓層後,該段路綫於一九 八零年三月之通車日期應不致蒙受影响,雖
