brick and cement, which the city must
furnish and deliver in accordance, with
the Stansbury & Powell contract men
toned in communication No. $50.
1T is estimated that the cost of brick
and cement needed to complete the new
outfall between the same points is
$S5, $50.
OBVIOUSLY IT WILL COST THE
| CITY .7S0 MORE TO SUPPLY
BRICK AND CEMENT FOR THE
PROPOSED SEWER THAN FOR THE
NEW OUTFALL.
Assuming that John Rchman can
construct the proposed sewer and fur
nish right of way for the net sum of
$3.50, 900, as proposed, then the proposed
sewer will cost the city $729,660. At
tention is directed 10 the fact that the
estimate by the engineer, department
exceeds this amount Y $234,34 1t is
not believed that the work can be done
for less than the estimate by the engi-
neer's department.
Three Miles to Be Built
"The distance from Vernon avenue
along the line of the new outfall sewer
to the terminus of the proposed sewer
is $4,000 feet, or 5.11 miles. When work
was taken up by the city about Decem-
Der l, 1906, the contractor had already
constructed 11,O27 feet, or 2.OS miles of
this distance, except a small amount of
back filing. leaving 1873 feet, or 3.O3
miles to be constructed; of this 1875
feet, or 1.S9 miles, was in the wet tun-
mel section.
Estimates made by the engineers s
department show that the new outfall
on the route originally planned between
the points above mentioned will prob
ably cost S490.230 including all work in
the wet tunnel section, which was esti-
mated to cost 1852, ,O49,
Work in Harper Regime
"On December l, 1906, the city active
ly began the construction of the new
Outfall and has organized a working
force, purchased and installed pumps
and other machinery, sunk 400 feet of
shafts. eXcavated and timbered 1920
} feet of the wet tunnel and laid 500 feet
of the sewer inVert.
! 1T is estimated that at least % per
cent of the work on the tunnel section
has been accomplished and it is GER
tain that work will proceed rapidly to
1 an early completion,
, "A COMPARISON OF THE ESTI-
MATES BY THE ENGI.JEER'S DE-
PARTMENT SHOWS THAT THE
PROPOSED SEWER WILL COST
/ $473,77O MORE THAN TIE ONE NOW
} UNDER CONSTRUCTION N.
. "A comparison of the cost on the basis
of the cost Of brick and cement plus
S25O00 John Rebman's proposal, shows
that the cost will still be $2S9, ,43O more
1 than the new outfall.
! Outfal Is Waterproof
