Second of four
stages of exca- vation near com- pletion
into Euclid 35 ton rear dump trucks. Using this equipment the pro- grammed rate of excavation was 40,000 cu, yd. solid measure of rock per month. However, toward the later stages of the site formation con- tract, as operator experience and efficiency reached a maximum, this rate was regularly exceeded in one month by as much as 50 per cent.
Originally the site formation con- tract had been scheduled to take 32 months to complete, but during 1966 the Hongkong Electric Company de- cided that the commissioning date for the first stage of the power station must be advanced and due to this and other considerations it was necessary to advance the completion date of the bulk excavation to the end of March 1967.
To achieve this, double-shift work- ing was adopted from the beginning of October, 1966. In fact, due to the high working rates, the bulk excava- tion was completed at the end of February, 1967, and all that remain- ed was localised trimming and levelling.
The disposal of excavated rock from a 14 million cu. yd. hill was of course a considerable item in the project. Two specially designed jet- ties were constructed on the south
enable the Euclid rear dump trucks to tip rock directly into barges moored alongside.
Most of this material was used in various Government sponsored re- clamation and typhoon shelter schemes. Initially, the rock was used to reclaim 600,000 sq. ft. of land for
future Government use from a bay adjacent to the site. This reclamation was completed towards the middle of 1966 and starting in March of that year rock was supplied for the forma- tion of the Southern Aberdeen typhoon breakwaters which, on com- pletion, will greatly increase the safe-
shore of the Ap Lei Chau site to 150 RB loading rock into a Euclid dumper on the south side of the site
