financial qualification to bid on any Fort Worth Water Department project.

as such.

and/or expertise. .
Any proposals submitted by a non-prequalified bidder shall be returned unopened, and if
inadvertently opened, shall not be considered. �
g. The City will attempt to notify prospective bidders whose qualifications (fjnancial or
experience) are not deemed to be appropriate to the nature and/or magnitude of the project
on which bids are to be received. Failure to notify shall not be a waiver of any necessary
prequalification.

acts of the Owner, fire, flood, tornadoes, epidemics, �
quarantine restrictions, strikes, freight embargoes, or delays
of sub-contractors due to such causes.
When the date of completion is based on a calendar day bid, a �
request for extension of time because of inclement weather

considered only when a review of the Contractor's purchase �
order dates and other perLinent data as requested by the
Engineer indicates that the Contractor has made a bonafide
attempt to secure delivery on schedule. This shall include '��
efforts to obtain the supplies and materials from alternate
sources in case the first source cannot make delivery. __
If satisfactory execution and completion of the contract
should require work and rnaterials in greater amounts or
quantities than those set forth in the approved Contract
Documents, then the contract time may be increased by Change
Order.
C7-7.9 DELAYS: The Contractor shall receive no compensation '�"�!
for delays or hindrances to the work, except when direct and ��

compensation is claimed a written statement thereof shall be
`" presented by the Contractor to the Engineer and if by him
� found correct shall be approved and referred by him to the
Council for final approval or disapproval; and the action
. thereon by the Council shall b� final and binding. If delay
is caused by specific orders given by the Engineers to stop
5 work, or by the performance of extra work, or by the failure
�„ of the City to provide material or necessary instructions for
carrying, on the work, then such delay will entitle th e
� Contractor to an equivalent extension of time, his application
for which shall, however, be subject to the approval of the
City Council; and no such extension of time shall release the
Contractor or the surety on his performance bond from all h is
� obligations hereunder which shall remain in full force until

the Owner will make no extra payment for stand-by time of
construction equipment and/or construction crews.
If it should become necessary to suspend work for an

� It has been determined by the Transportation and Public Works Department that the strip of
existing HMAC pavement between the existing gutter and the edge of.the trench pavement� repair
will not hold up if such strip of existing pavement is two (2) feet or less in width.
� Therefore, at the locations in the project where the trench wall is three (3) feet or less from the lip
of the existing gutter, the Contractor shall be required to remove the existing paving to such
gutter. Th� pavemenf repair shall then be made from a minimum distance of finrelve (12) inches
� outside the trench wall nearest the center ofi the street to the gutter line.
The pavement shall be replaced within a maximum of five (5) working days, providing job
� placement conditions will permit repaving. If paving conditions are not suitable for repaving, in
the opinion of the Owner, the repaving shall be done at the earliest possible date.
� A permit must be obtained from the Department of Engineering Construction Services Section by
the Contractor in conformance with Ordinance No. 3449 and/or Ordinance No. 792 to make utility
cuts in the street. The Department of Engineering will inspect the paving repair after construction.
This permit requirement may be waived if work is being done under a Performance Bond and
� inspe�ted by the Department of Engineering.

place pipe consists of a resin impr2gnated flexible tube, coated with an elastomeric
coating, when inverted into an existing sewer pipe through existing access manholes, and
which, under proper hydrostatic and thermal conditions, is cured-in-place, becoming a
structurally sound cured-in-place pipe. The thickness of the pipe will be dictated by the
structural� requirements of the sewer pipe with no loss of cross sectional area other than
the thickness of the resin-impregnated tube. The pipe will be impermeable to water,
provide corrosion resistance, and an optimum friction factor for the sewer flow. Branch
connections shall be reinstated by a remote controlled cutting device.

4. Cleaning of Sewer Line - It shall be the responsibility of the Contractor to remove
all internal debris out of the sewer lines and flush the sewer lines clean, disposing
of debris off-site. Debris is not fo be washed downstream into other sewers. All
solids or semisolids resulting from the cleaning operations shall be removed from
the site and disposed of at no additional cost to the City. It is the responsibility of
the Contractor to secure a legal dump site for the disposal of this material. All'
materiafs shall be removed from the site no less often than at the end of each work
� day. All cost for the above-described work shall be paid for by the price bid per
linear foot for Cleaning and Television Inspection.
5. Inspection of Pipelines - Inspection of pipelines shall be performed by experienced
personnel trained in locating breaks, obstacles, and service connections by closed
circuit color television. Television inspection shall be in accordance with the
specifications contained herewith for "Pre- and Post-Construction Television
Inspection of Sanitary Sewer Lines".
INSTALLATION OF THE RESIN IMPREGNATED TUBE:
The Contractor shall designate a location where the uncured resin in the original
containers and the unimpregnated fiber-felt tube will be vacuum impregnated prior
to installation. The Contractor shall allow the Owner to inspect the materials and
"wet-out" procedure. A resin and catalyst system compatible with requirements of
this method shall be used. The quantities of the liquid thermosetting materials
shall be per manufacturer's standards to provide the wall thickness specified. All
felt shall be impregnated under vacuum. �
2. The wet-out fiber felt tube shall be installed through an existing manhole or other
approved access by means of an inversion process and the application of a
hydrostatic head sufficient to fully extend it to the next designated manhole. The
impregnated tube shall generally be inserted into the vertical inversion standpipe
with the impermeable plastic membrane side out. At the lower end of the inversion
standpipe, the felt tube shall be turned inside out and attached to the standpipe�so
that a leak-proof seal is created. The inversion head will be adjusted to be of
sufficient height to cause the impregnated tube to invert from manhole to manhole
and hold the tube tight to the pipe wall and produce dimples at the side
connections. A lubricant, if used, shall be as approved by manufacturer's
standards. Manufacturer's standards shall be closely followed during the elevated
temperature curing so as not to over-stress the felt fiber and cause damage or
failure prior to cure. In certain cases, the Co tractor may elect to use a top
inversion.
3. Curing: After inversion is complete, the Contractor shall supply a suitable heat
source and water or steam recirculation ec�uipment. The equipment shall be
capable of delivering hot water or steam throuighout the section by means of a pre-
o4i�siss ASC-5

'Uniformly raise the water temperat�re above the temperature required to effect a
cure of the resin. This tempera�ure sha11 be determined by the resin/catalyst
system employed and shall be per �nanufacturer's standards.
�
4. The heat source shall be ftted with�suitable monitors to gauge the temperature of
the incoming and outgoing water or steam supply. Another such gauge shall be
placed at the remote manholes to determine the temperatures during cure. Initial
cure shall be deemed to be completed when inspection of the exposed portions of
the cured-in-place pipe appear to b� hard and sound. The cure period shall be of
a duration recommended by the resin manufacturer, as modified `for the inversion
process, during which time the reci��Culation of the water and/or steam and cycling
of the heat exchanger to maintain tt�e temperature continues.
e �
5. Cool-down: The Contractor shall � cool the hardened cured-in-place pipe to a
temperature below 100 F beforeA relieving the static head in the inversion
standpipe. Cool-down may be ac�omplished by intraducing cool water into the
inversion standpipe to rep{ace wat�f or steam being drained from a small hole
made in the downstream end. Care'shal4 be taken in the release of the static head
so that a vacuum will not be developed that could damage the newly installed
cured-in-place pipe. ,
�F. SERVICE CONNECTIONS: After the �ipe has been installed, the Contractor shall
reconnect the active service connectio'i�s. This shall generally be done without
excavation, and, in the case of non-man e�ntry pipes, from the interior of the pipeline by
means of a television camera and a cutti�g device that re-established them to not less
than 90 percent capacity. Existing services shall be reinstated within 18 hours of
installation. Should internal reinstatement not be possible, the services must be
reconnected externally by excavation imrrjediately. Service saddles acceptable to the
.Engineer shall be utilized. Backfill at se�vice connections sha11 be cemen� stabilized
(2 sacks per cubic yard) to a point 12�� inches above the service lateral to trench
intersectian and shall be in accordance witj� these specifications. Each reconnection shall
be paid for separately. Six inch sewer lin��s shall have service connections completed by
external means. Contractor may re-connect the 6" sewer line connections by internal
me�ans in special cases with the approval q„fthe Engineer.
G. ACCEPTANCE: The finished cure-in-plac�tpipe shall be continuous over the entire length
of an inversion run between manholes andlbe smooth and free from substantial wrinkles,
as well as defecis, and improper house co,nnections. Should any of these defects occur,
the Vine shall be excavated, repaired andlqr replaced and complete restoration made to
the satisfaction of the City at no additionaf c�ost.
The watertightness of the pipe shall be tested for leaks under a positive head during cure
with allowances,being made for end leakage and temperature effects.
s
,r
H. CLEAN-UP: Upon acceptance of the ins�allation work and testing, the Contractor shall
restore the project area affected by his oper',afions to original or better"conditions.
1. PATENTS: The Contractor shall warrant and save harmless the City and all of its ofricers,
agents, and employees against al� claims for paient infiringement and a;ny loss thereof.
