embedded in decomposed granite; in these cases, dredging operations were only carried out to the depths of the
boulders; alse over a length of about 100 feet of trench
which has been dredged to a depth of 80 feet below L.W.0. 9.T.hgrond which depth the dredger is unable to operate. The material in the bottom of this portion of trench is decomposed granite with pockets of Kaolin.
Drawing - D shows a cross section and elevation
of the quay wall designed by Mr. John Duncan, late Port
Engineer, and which the Netherlands Harbour Works Company
have contracted to construct in the position referred to
in paragraph 1. It will be noted that, to form the foundations for the quay wall, sand fill is permitted in
the dredged trenches to a level of 39 feet below L.W.O.S.T.
above which is deposited 2 feet thickness of quarry spalls, the foundations being completed by the deposition of pell
mell rubble to the lines and levels shown on plan.
Prior to Mr.Ihmcan's retirement on the 31st
March, the contractor had been unable to procure sand of
the quality specified in the Contract for filling in the
dredged trench, a finer grained sand, however, was brought
on the works ami its use was approved for filling in a
length of about 170 feet of trench to the level of 47 feet
below L.W.0.8.1. between the points Y and ▼ show on Drawing - B: this work was completed about the end of
March. Above this sand fill about 5 feet thickness of
quarry spells have since been deposited and the foundation
cœpleted by the deposition of pell mell rubble composed
of stones weighing 1 to 5 orta., the foundations seaward
of the quay wall will be protected by 1 ten boulders set
hard to hard.
Since Hr. Duncan's retirement, although the
contractor has brought sand on the works equal to the
quality specified, he has not been permitted to deposit
