! one of which is known as the Clear
water extension" There being no
controversy over this portion, we have
not included it in this report except
| as to the general character of all the
work done Besides the other two
supplemental contracts we find alter
atoms in the quantities required to be
built by the contractors: some dimin
ished. some increased-and these we
have set forth in a bill, or final
estimate" thereto attached) showing
the net increased or diminished guam
titles. The prices in most cases had
been agreed to by contractors and
city before the work was DONE In
all other cases we have fixed prices.
using our best judgment as to current
practice where extra work is ordered.
BY actual measurements, and from
records at our command we have de-
termined the quantities of increased
or diminished work. Increased work,
as shown by our estimate, amounts
to $1,OO3.11, and the decreased work
amounts to s2sS.42. giving balance
in favor of the contractors. above con-
tract price of $714.69. This amount
considered alone might seem great,
but taken in connection with all the
notifications. changes. as we'll as the
relaying Of $50 feet of 12-inch pine.
for which $3.50 was allowed, it is less
than per cent of the entire contract.
We would respectfully call your at
tention to the fact that a more COM
plete sewer record should be kept. OF
the $50 house branches (approvi-
mately) inserted, the records show not
more than $50 recorded. A good man
should be made. showing all the lots.
blocks and other subdivisions of the
land subject to taxation for this i'm
provement. This map should also
show the location of every Y-branch,
the exact length of the several sizes
Of sewers. as well as the location and
character of each structure in the sys-
tenn. The Y-branches and house lat
erals whose locations have been omit
ted by the inspector should be prompt
~ located now. then indicated on the
map in such manner that they can be
easily relocated on the ground at any
future time with certainty. This part
OF the work is as important as any
construction work.
The specifications provide that an
excavating the bitches no tunneling
will be allowed except with the con-
sent of the engineer, and in no case
will any tunneling be allowed in such
manner as to preclude sufficient light
for the proper cementing and laying Of
the pipe, and no tunnel shall be more
than 10 feet long" The purpose of the
specifications was to secure proper
jointing of pipes and thorough back
filing These details have been al
ready reviewed, vet we may say that
we personally opened one of these
tunnels, permitted in the prosecution Of
the work. and the joints at this place
were perfect. Backflling in tunnels is
rarely as efficiently done as in open
cuts, even though water is used for
pudding yet OIL the other hand set
Ting rarely takes place directly over
tunnels.
The following is our estimate of the
amounts earned by the contractors,
