q specifications call for one inch

sharp. After laying about $500 go.
Yards of bricks with sand answer
ing the require ments OF the spaci-
ncations Mr.. Hudson complained to
re that he was unable to obtain
'le san from Resugio with sutfi
cient rapidity and that he was be-
Ing delayed In the work from this
cause and asked permission to use
Tue local sand claiming that it was
even better than the imported sane
TOT cushion purposes. On examining
the same / found the sand WIS mix
cd with from 10 percent to Is per
cent river silt, but did o consi
aer this a detriment, in fact, in
my opinion 1t is really better for the
purpose than the sharp sand called
Ior In specifications. | not anly went
on my own judgment in the matter,
put submitted it to several other
engineers who concurred with me.
! then told Mr.. Hudson to go
anead and use the local sand with
the understanding that to offset the
saving in cost the paving company
would put in concrete headers at
all points when paving terminated.
These headers were lot called for
under the contract and would come
an under the head of extra work.
am prepared to produce evidence to
show that 1t is customary to include
headers in the proposals and con-
tractors bid on same at so much per
lineal foot. Some specifications call
for the headers to be included in
the price per SO. yard OF pavement,
but where no mention IL made OF
same naturally it is taken are OF
under the head or extra work. A
contractor in making his estimate
naturally figures only on the work
called for in the specifications and
expects to be paid for any additional
work not covered by the specifica-
tions.
The fve year guarantee Furnished
by the paving company contemplates
covering any general deterioration OF
the work. But. for instance should
the city fail to provide proper curbs
along the sides OF the pavement, We
should not expect the paving com
pany to supply same in order TO hold
the paving in place. The concrete
headers furnished by the paving
company are five inches wide and
from 10 to IL inches deep and IL
is ridiculous to estimate that this
class of work could be constructed
at a cost of 2 1-2 cents per lineal
foot. For comparison our sidewalk
contractors are paid fifty cents per
loot for concrete curbs six inches In
width and Is inches deep and Mr..
Hudson's estimate OF 35 cents per
lineal foot compares favorably with
this price. Under Mr.. CObolini's es-
innate the cost OF an alley heade,
of 20 feet would be $40. Using
the proportions OF 1876 which is
used in these headers the cost OF is
what Inc material alone would be a.
follows:
Gravel 10 of IA Gu. Yd.. ....... go
Sand Tvs OF e Gu. I'd. 80
Cement 1 $40 sacks. IS

This would make the cost OF me-
terial alone $2.27 for 20 feet head

| herewith submit estimates from
the following contractors for this
class OF work, all owing a reason
able profit to the contractor.

There are in all eight hundred
feet OF these concrete headers which
at a price of 80 cents Ter lineal foot,
five cents lower than Mr.. Hudson's
price would be $4,000 adding to this
the extra work for which Mr.. Hud-
son rendered statement on May the
goth amounting S454.35 and adding
the following extra work since per
formed by the paving company
namely, replacing concrete and paw
ing torn up around federal building
in rebuilding new sidewalk approx
mately so sd. yards at $500 per
81. yard would amount TO $4,000
making q total extra bill OF sS14.35
70 offset this we have allowed the
having company to use local sand
under 1880 So. yards OF paving.
One cubic yard of sand n inch
chick covers thirty-six so. yards "f
area under $4,000 SO. yards OF pave
ment this would amount To CSC Gu.
yards but as the paving company
used the sand called for in the srec-
ihcafions under $500 so. yards OF
pavement they actually used only
4s6 Gu. yards or local sand for sand
cushion.
The specifications do not call FOR
. clean sand for top dressing. but a
dne clean dry sand and ] consider
the local sand answered these speci-
dcstions aud accepted same as suel
without question.
