Ions.
As you will see by the plans sub
mitted and in the specifications. n
have provided for connections be
tween the proposed reservoir and the
present one in use, to meet all pur
poses and occasions that may arise
In giving YOU an estimate of the
cost OF this work as contemplated, It
is practically impossible to designate
it mile by mile, but the average cost
per mile of the pipe construction as
designed and submitted will be ms
follows:
Twenty-four inch pipe, $3.50 per
loot 2O-inch pipe, $2.1O per foot
l6-inch, pipe SLIGO per foot.
A reservoir with capacity as stat
ed lined either with concrete or as
phaltum will cost approximately $780,
900.
l have considered It advisable to
eliminate the construction of the in
take from the present specifications
and let that come in a separate con
tract, but in the manner in which
ii should be built or constructed. /
would say that the cost of the same
would be $4,000.
The installation of two wire tele-
phone line from the intake to sta
tion 290, distance of about miles.
including the instruments necessary
for its operation, can be built at about
10000 per mile.
Having agreed to give you the cost
of various kinds of pipe. and taking
into consideration that there is only
one other class of pipe that could be
used with the probable amount of
money available for this purpose. I
will give you the comparative cost
of riveted steel and machine band
ed wood pipe as above referred to.
Riyeted steel-16inch, S1.S7 per
foot; 20-inch, S2.S7; 2i-inch, So
Ga. per foot
You will readily see that the wood
en- pipe is much below the cost of the
steel pipe, and in my opinion. from
vation. it is far more preferable than
the steel pipe.
Owing to the unfavorable condi-
tions of the weather / have been un-
able to keep my men in the field and
prosecute this work in the time as
specified. but desiring to render you
a most thorough and complete set of
plans and specifications, | have taken
the liberty of extending that time.
trusting that You viii consider it in
a proper spirit. and that any delays
that have occurred could not be at
to negligence on my part.
| would further state that the pres
ent capasity of the reservoir now in
use is 1892. 900 gallons.
The number of cubic yards of earth
and rock to be excayated for the line
as surveyed is 39.592.
The average cost Of eXcavating
said line. owing to the nature of the
ground, much of which is solid rock
requiring blasting, and the dinicul-
ties to be encountered in taking care
Of the necessary labor camps. etc,
and transportation of material will
be approximately go cents per yard.
I estimate the cost of trestle work
boxing and packing OF pipe to be
81 900.
