OVERPAY $4,000
ON BIG SEWER
KINGSBURY REPORT SHOWS
ACTUAL MEASUREMENTS
Experts Advise Authorities That the
OutfaIl Work Can Be Finished,
City Employing Its Own
Labor

The report of Acting City Engineer
Kingsbury on the amount Of work
completed on the outfall sewer was pre-
scented to the board Of public works
yesterday.
The figures given by Mr. Kingsbury
are the result of careful survey and
are warranted absolutely accurate.
Through these figures the board has
estimated that Stansbury & Powell,
the contractors, who gave UP the work,
have been overpaid to the extent of
SS9, 900, more than was at first anttci-
pated.
Mr.. Kingsbury's report is as follows:
II herewith respectfully submit a
report of the amount of work done to
date on the new outfall sewer.
"Section Length, 1887 feet;
length completed, 5139.5 feet.
"Section 2-Length, 10,63322 feet;
length completed. 6S75.5 feet.
Excepting 1880 feet of back filling
and the construction of two manholes.
"There is also 200 feet of three-ring
invert completed and 45 feet of three
ring invert two-thirds completed.
"There is also As feet excavated 10
feet of the required 12 feet; 325 lineal
feet excavated 13 feet of the required
Is feet; 20 lineal feet excavated to
grade, and 1913 lineal feet excavated 3
feet of the required 20 feet.
"Section 3--Length, 12T96.46 feet, of
which 1O752.75 feet is tunnel work.
Length of tunnel completed 1887
feet. There is also 81 feet of invert

"Section 4-Length 1850 feet; length

back filing feet deep $50 feet back
filling feet deep, 115 feet back filing

deep, one manhole to be constructed;
1O43 feet to be covered to a depth of
IL feet 1920 feet to be covered to a
depth of one foot; 1910 feet to be COW
cred to a depth of feet; 1877 feet to be
filled to a depth of feet: 900 feet to be
filled to depth Of 6 feet. There is
also 1926 feet of fill brought to the
grade of the bottom of the sewer,
where the sewer is to be constructed on
fill.
Section 5-Length. 12,112 feet; length
completed, $3.50 feet. Also 79.5 feet of
invert completed, 81 lineal feet of brick
work. consisting of the outside ring of
the invert, completed, and 300 lineal
feet Of trench eXcavated to grade, eX-
cepting manholes to be constru cted;
134S feet back fling 81 feet deep and
1850 feet back filling 9 feet deep. The
ground has settled over the tunnels
between stations between $40 plus 46
and SIS plus so a depth of feet for a
distance of 40 feet; between sta ations
$50 plus 3S and 565 plus AZ a depth of
feet for distance of SO feet: between
stations 545 plus 26 and $50 plus 20 a
depth of 4 feet for a distance of "a feet
"Section 6-Length 5913.75 feet. less
220O feet of old outfall sewer left In
place. leaving 3113.75 feet OF new
sewer which has been completed. ex-
cepting IS feet of arch and the inner
surface of the old outfall sewer to be left
in place and used in connection with
the new sewer, which is to be cleaned
and plastered.'
AS to Cost
No one has yet presumed to estimate
the exact cost of constructing the re-
mainder of the outfal1 sewer.
William Mulholland and ]. B. Lippin-
colt, engineers of the water board,
made the trip with the board of pub
lie works and the city engineers last
Tuesday, and Messrs Lippincott and
Mulholland submitted a report to the
board yesterday from an engineering
standpoint.
In this report both claim the tunnel
section can be finished, and advise
that the city undertake the work, en-
ploying its own labor.
They find that with the exception of
some Of the back filing the work so
far accomplished is well done.
This is what Messrs. Lippincott and
Muholland have to say:
eve found that the difficulties en-
countered in the portion of the line
northeasterly from Inglewood are
clearly shown in the profile which was
exhibited to the contractors at the
time of bidding. and that the specifica-
tions particularly require personal in
spection on the ground by the con-
tractors prior to bidding.
I'VE noted that at points where the
difficulties were encountered. particu-
larly with water, the plant as installed
was small and obviously Inadequate to
cope with the situation.
Expensive and Tedious
1--WE consider that 1t has not at all
been demonstrated that 1t is impos-
sible to construct this tunnel. 1t will
plainly be expensive and tedious to
finish the tunnel portion Of the work,
but the effort undoubtedly should be
made, and we believe that with a
proper installation of plant it can be
successfully completed, 1t is quite
possible that several different methods
of work will have to be tried before
1t is completed, N ofder TO meet unex-
pected emergencies
"If a large air comprising. plant
can be installed and the water pro-
gressively pumped from a series of
driven case wells which are located a
few feet in advance of the tunnel head
ing, 1t may be feasible to depress the
water plane Immediately in advance of
the excavation in such a way as to
facilitate the driving of a tunnel and
the placing of the masonry
"If YOU so desire, we believe it Is
practicable for the city to do this work
itself, employing its own labor. and
we wish to express our confidence In
the ability of Homer Hamlin. your
new city engineer, TO economically
carry through such an undertaking"
