CONCRETE, TERRA GOTTA. AND
OTHER CONSTRUCTIONS.
| When the structural use Of concrete Is
proposed a specification, stating the quail
| ity and proportions Of materials, ana the
! methods OF mixing the same, snail be
submitted 20 the inspector when so de-
! sired by him who may issue permit at
his discretion and under such further
conditions, i'm addition to those stated, as
he sees fit to impose.
Terra Gotta wall facings may be loaded
not to exceed five tons per square loot OF
available or bearing section. When nara
hollow brick are used as the inner racing
of a hard selected brick wall the wall
! shall be estimated the same as KIN run
brick Where hollow tile blocks are used
| for building partitions or other walls the
effective or bearing parts OF the tiles
! shall not be loaded more than eighty
! pounds to the square inch Tor nara IRE
/ clay tiles, nor more than sixty POUNDS Tor
hard ordinary clay tiles, nor more than
forty pounds for porous tiles. Portland
| building blocks used for outside or other
hol no loaded TO more imam
one hundred and forty pounds per square
inch of effective or bearing section.
FOOTINGS.
The footing courses of foundation walls
shall be OF stone or concrete, or stepped
| up brickwork, or steel beams bedded IN
| concrete, or a combination or any OF the
same; all to be OF sufficient thickness,
! strength. and breadth to sately pear the
| weight imposed thereon.
Stone footings shall consists or hard
large slabs not less than six inches thick
If the footings be Of Portland concrete
il shall not be less than twelve inches
! thick per course and the offsets shall not
/ exceed three quarters or the thickness
of each course or after the first course
is laid the sides up to the bottom OF other
footings base plates or foundation walls
| NAV be battered with the above ratio,
! II stepped up footings Of brick are used
the first course If not laid on concrete
| snail be TWO COURSES lHIsh, anu Nlic OiA-
! sets II laid in single courses shall not
| exceed one and one-half inches. or II
! laid In double courses shall not exceed
/ three inches. Nothing in this section
! shall be so construed as to prevent the
use Of reinforced or armored concrete IL
properly proportioned,
PILES, HOW DRIVEN. ETC.
Sec r. Whenever piles are required to
be driven for foundation they shall be
lrix a
solid bearing. and II OF wood the tops
shall be cut off below the lowest ground
water or tidewater level so as to insure
constant immersion. They shall not be
spaced exceeding thrty-six inches or
nearer than two feet on centers. and
there shall not be less than two rows
OF piles under all external, party, or
other walls less than seventy feet high,
excepting under walls not exceeding
twenty-five feet In height a single row
of piles may be used II all other cond
tions of stability are complied with.
No wooden pile used for building
foundation shall be weighted with load
exceeding twelve tons. Where ranging
and Gaping timbers are laid on piles
for foundations. they shall be not less
than six inches thick properly Joined to-
gether and their tops laid below the
| lowest water line.
Where required. Portland concrete shall
! tween the heads OF the piles to the depth
and thickness OF at least twelve inches,
| and for one foot in width outside OF the
! piles Piles may be made OF concrete,
! either reinforced or plain. Plain con-
! crete piles must be nodded in place by
| methods which are reasonably certain TO
secure perfect, full sized piles: reinforced
! concrete piles, II properly designed TO
! resist the shock Of driving, and If driven
with a cushion TO lessen the shock, or
! II put down by water jet, may be nodded,
/ allowed TO harden, and then driven to
| place. In case concrete piles are used,
| whether reinforced or not, their bearing
/ power shsl be determined by putting in
] one or more test piles and loading them.
| after the concrete Is sufficiently hard.
! The full working load in the structure
! shall not be more than one-half OF the
| load under which the piles begins to set
| tie In no case, however. shall the load
on a concrete pile exceed twenty tons per
square foot OF cross section OF concrete.
! plus six thousand pounds per square inch
| Of any longitudinal steel reinforcement.
! WoodeA piles may be used for the
| foundation under frame buildings built
over the water or on tide flowed land or
similar land. i'm which case the piles may
| project above the water sufficient
height to raise the building above the
highest water level, and the building may
be placed directly thereon without other
foundation.
FOUNDATIONS OF BUILDINGS
Sec 13. All brick buildings shall have
foundation walls built OF stone. brick
Portland concrete. iron. or steel. All
stone and brick walls shall be laid up
with cement mortar. IL built Of rubble
stone. they shall be at least eight inches
thicker than the wall next above them
to a depth of twelve feet below the curb
OF ground level. and II built OF brick or
Portland concrete shall be at least four
inches thicker than the wall next above
them TO a like depth below the curb or
ground level: the thickness OF said walls
below said twelve feet shall be increa sed
four inches for every ten feet or addi-
: tional part thereof. II. in place OF a
continuous foundation wall. Isolated piers
are to be built to support the superstruc-
ture. where the nature OF the ground and
the character Of the building make II
necessary. Inverted arches resting on a
!. proper bed Of concrete shall be turned
= between the piers. The thrust OF the
!, = outer piers shall be taken up by suitsble
