2. MID project 0al.1 A to Met the terms or the aTecifica'alons and Contract in four
major respects Which mill be enumorated as f031eW3 -*
(a) Longitudinal. Cracks: The cpecificatlone provided for a.•tandsrd strenr1th
reinforced concrete pipe placed on shell. embedment- The height Of the fi3.l
over the pipe ranged in the vicinity of 20 to 22 feet. Loads or Conditions
that cause stresses in, sewer piped include external loads, handl.i&& taryere
tore, and internal t-ursting pressure. The Brat is the most itmportant and
any be the =17 stress considered in dasigmm. Strength cufPicient to resist
external loads mill be sufficient to resist other stresses. Ttie' adequacy of
EL pipe to resist externl loads Is dependent upon a number of factors the,
meet important of whieh are the type of embedment used under the plr s �
mp
height of the trench above the pipe. P.nother important factor involves the
width of the treueb at the level. of the top of the pipe. The specifications
in this rase provided for shell embedment under the pipe. It is in such loca-
tions that the longitudi—I crack first appeared. The epbcdment was then
changed to concrete cradle which gives a mach firmer foundation sand, f011*u-
inG this change in construction procedure, the crack was no longer a0uraut.
It is the wri'ter's opinion that the Pipe Was UXAE T- decigned VOr the cond3.-
tions as em'tedmeFZt mqulred under the specification$ and the heist of fill-
Such under- deai.ga may not have exceeded the normal. Ee.£ety factor and may not
have caused craeka. The overicrai condition Was aggravated by wet beddinz con•
di.tions and ditch slaaagbing, Ord by combination of fectore the cracks did oc-
cur. The fast that Cracks, no loreer appeared where concrete cradle was used
seems to bear out WL; opinion. The crack itself has over a period of the
pact 6 nontho tended to hea itsrl.f, a condition which is'inherent with con-"
Crete under load. Correct-Iva measures, were expsusive rand, under the circum-
otauces, could not logically be required of the Contraotor. -It to the
vriter'c opinion that the give i-rill serve a useiizl lire, but it must be
?,ointed out that any time re orcing steel. in a pipe is exposed in A1W way
uhatsoevcx to the action of hydrog= suUlde 9W which is iouaaed in an eau- .
itarJ uevers, ttaat the lffe of the pipe will be shortened.
(b) Certain settlement occurred in the Gov line of the pipe again In the
uxcaa where ahell ambedweat was used. A portion of the nettlement was so
Great as to neoeasitate rexmilng and xeWing portiona of the y4N howcr.rer,
there were other cectiow in which the Oattlmmt was oft grade by less than
an inch and these portions were not relaid. Sewers on a. grade as flat as
exist in this project will toad to silt up + ;htl3 so that the,.i3.ov lite

type of filler be i+7aeed in the *_'low 11na Gi the pipet since this zZtexio7.
vill., in all likelihood, detach itself in ca very short UU0 and end up its
the senate treat at plant itself.
(c) Specifications required an ~ .o'il:4ratior. teat to test the water tigh'tnesa
or the pier. Ouch teat Would require that the McUre sever line be Goarplete-
17 filled with water to a zoUt tome la feet above. the flow line of the pipe.
The vatcr would then vam in for a two -hour test parlad rafter which the lose
of voter would be checked in order to dota=lue whether or not it lads ;ed the
opeciyications. The specifications ,provicde a for the exCatration ntat to ex-
ceed the rate of 30,000 Alone Z*r 24 hours Par exile Of sewer line being
tested. The end objective car: a test of ra @ewer in not to detc -Mine how
saueh water will leak out of the 91pe, but the reveroe, to determine how match
vace
waster may soap into the pipe, which lneresseg the ultimate load on the as
treatment pUmt. At the writer's diveetion the contractor performed whet is
termed an "inailtration te^,t" by blocking upiboth the upstream and the ern-
otream end, utter Virst thorouGhly drying the sewer. The flow of water into
the pike throw cracks or throuJi joints was observed over sa period of
tir•r_,. The results fear surpassed the requirements ua pooed by the opecilica-
tions thus indicating that an joints were water -tight nrO that the lont31-
tudinal erackD had sufficiently closed to preaout awl furthcr infiltration
oZ ground ;eater. A credit of �300 was offored the City by the contractor
and wars accepted tnj the Director of rvublie dlarkn.
(d) Tize® The contract docussents provided for -3{x7 caler -der daz with a
tilde o-, completion established for 7 .iuI;) 1559. Due to =croua difficulties
vhich arose between tho contractor and the Department of Public Works dvriuZ
the early and rAddle parts of 1;59 end due to changes in porstntnel, -time
charges were ap- varerkUy cliare.aardcd. Rowe-Ter, the Westside SewaGe Treatment
dent was not accepted until 3 Febru=7 15ZO ate- the WeStsida Trunia Sewer
Main could not have been placed in operation prior to that date. Moreover,
there %tare no customers to be srars*ed W the Westside Trank :newer go. I and
it is the writer's opinion and recomendation• that the City has 'not LUVOrc d
g
as a,re mAt of failure to complete witbin the required anti syecifie:d thee.
3. All tests an inspectiow of the 'project have 'meta completed indicatinG satis-
factory construction with the above except #oast, and it It therefore zW recoIImmla-
tion that the•project to accepted and that payment in the amount of thin estimate,
$41,2134.90, to paid from funde•previoucly appropriated. a_
