Within the classifications the following shall each be given separately:

(i) Preliminary piles.
(ii) Test piles.
(iii) ContiguoUs bored piles
(iv) Raking piles according to angle of rake in increments of 10°. The inclination
corresponding to the rake angle increments, stated as the ratio of horizontal
displacement to vertical distanoe are as follows:

Inclination angle Ratio
10° 1 in 5.6715
20° 1 in 2.7475
30° 1 in 1.7320
40° 1 in 1.1917

(v) Piles to be extracted shall be identified and given separately.

2. Within the classifications provided in accordance with claUse E.5.1, items shall be given in
accordanoe with clauses E.5.3-5 grouped under sub-headings which state the following:

a. nominal cross sectional size.
b. the materials of which the piles are composed and in the case of steel piles, the
nominal weight per metre (the materials of which piles are composed should not be
taken to mean only some of the materials in a pile. For example: if a timber pile is to
be ringed, this together with the details of the requirements should be stated.
Similarty, precise definitions of grades of steel and of concrete mixes are required.)

3. For piles other than cast-in-place concrete and interlocking steel piles, items shall be
given for:

a. The total number of piles stating the specified length. The size and weight of heads
and shoes shall be stated in the description.
b. The total driven depth given in metres.

4. In the case of cast-in-place concrete piles, items shall be given for:

a. The total number of piles.
b. The total concreted length of the piles given in metres.
c. The total driven or bored depth given in metres stating the maximum depth.

5. In the case of interlocking steel piles, items shall be given for:

a. The total area of piles given in square metres classified into the following ranges of
piles length:

Not exceeding 12.00m
12.00m - 24.00m
exceeding 24.00m
b. The total driven area of the piles given in square metres.
c. Corner, junction, closure and taper piles, where specifically required, shall each be
given in metres as extra over.
