brick, stone, iron, steel or concrete laid
on the solid ground or level surface of
rock, or upon piles or ranging timbers
when solid earth or rock is not found.
Piles Intended to sustain a wall, pier
or post shall be driven to a solid bear
ing II practicable to do so, and the num-
Der of such piles shall be sufficient to
support the weight to be imposed there
on. No pile shall be used of less dimen-
sicns than five inches at the small end
and ten inches at the butt for piles TWEEN
ty feet or less in length; and twelve
inches at the butt for piles more than
twenty feet in length. No pile shall be
weighted with a load exceeding fifty
thousand pounds. When a pile is not
driven to refusal. it's safe sustaining
power shall be determined by the fol-
lowing formula: Twice the weight of the
hammer in tons multiplied by the height
of the fall in feet, divided by the least
penetration of pile in inches plus one, I'M
der the last blow.
The Commissioner of Public Works
shall be notified of the time when test
or initial piles will be driven, that he
may be present in person. The tops of
all piles in permanently wet earth shall
be required to be cut off at least nine
inches below footings, and concrete shall
be rammed down in the interspaces be
tween the heads of the piles to a depth
and thickness of not less than nine
inches, and for one foot in width outside
of the piles, and the piles properly sealed
with nine inches of concrete on top.
Provided, that if pile construction is
used under water and ranging and cap
ping timbers are laid on piles for founda-
tions, they shall not be less than six
inches thick, properly joined together, and
tops laid below low water mark
Where metal is incorporated in or forms Is
shall be thoroughly protected from rust
by paint, asphaltun and concrete.
