extension of the site formation contract (originally due for completion on 15th January, 1957) until 15th July, 1957. It is of paramount importance that all the retaining walls, and some of the more important foundations, be completed before the onset of the 1957 rainy season, if extensive erosion over the whole of the site is to be avoided. A number of variation orders were issued in respect of the site formation contract, involving additional expenditure of $62,645.21. The principal item was for removal of additional excavation in connexion with the piling of retaining walls on the eastern boundary, which cost $45,730.60,
Concurrently with site formation, work progressed on the plans for the general contract, and in November 1956, these were approved by the P.W.D. Messrs. Langdon & Every, who were appointed as Quantity Surveyors for the job in April 1956 (but whose services were not required on site formation), immediately proceeded with preparation of Bills of Quantities, and by the end of March 1957, the work was almost completed. It is hoped to go to tender for the main building contract in June 1957.
The Conditions of Grant of the site (No. I.L. 7343) were finalized at the end of 1956. The amount of the premium (@ $2.50 per sq. ft.) comes to $402,500, and annual Crown rental will be $7,392.00. Discussions took place with the Water Authority about a mains supply: confirma- tion was received that it will eventually be necessary to build a new service reservoir to meet the requirements of this district, but in the meantime a temporary tank will be provided to give a supply up to a level of at least 200 ft. O.D. It may be necessary for flats above this level to be supplied by means of a pump, feeding a reception tank.
The supply of flushing water poses another problem: it was origin- ally hoped that the various underground streams running through the area, and which caused so many complications during the progress of site formation, would be sufficient, when collected, to give a daily flow sufficient to supply the whole of the estate. The daily flow is estimated at about 15,000 gallons during the dry season enough to give each flat about 20 gallons a day. This water would be collected in an under- ground tank situated at 96 O.D. level, and pumped up to the existing storage tank, which has been built at 150 O.D. This supply will serve by gravity flow about 150 flats below this height, and from there water will have to be pumped to 270 O.D., to a 9,000 gallon capacity storage tank, to serve the flats at the upper levels. It was anticipated this supply can be maintained without much variation throughout the dry season (during the summer there will be an over-abundance of
