Dear Mr, f:onrad:
Please find attacned four copies of proposed Change Order No. 5
for final approval and processing by tfie City of Oshkosh.
Froposed Change Order No. 5 consists of six separate items
as descriLed on sheet no. 'L of the change order document.
Also attached for your infornation in the review of these
change order items is the backup documentation for each item.
Fluor has suLmitted individu�il proposals for eact� of these
items. Eacf� of these proposals have been reviewed by IiNTB
and are found to be acceptable in the final amounts as
indicated on the change order documents.
For your use in evaluation of each of these items the following
summary has been prepared. A brief description of each item
is given along with the reasons for the change.
em IJo. 1
This item is for the extra work required to encase the electrical
primary ertrance conduits as :hey pass throuah rhe equioment
access room. It is a code reyuirement that the electrical
conduits be encased throughout their entire run in the interior
of the structure until they pass into the station switchgear.
The contract plans only showed concrete encasemznt for the
cond�its as they passed through the Low �ift Pipe Gallery.
It was necessary that the primary entrance conduits aiso

run through a portion of the Equipment Access Room. The contract
documents did not show the conduits being encased as they
passed through the Equipment Access Room. By letter dated
July ll, 1y84 HNTB requested encasement of the conduit. By
letter dated February 20, 1985, Fluor Construction Co.
forwarded their additional costs for the additional
encasement.
Y
Item No. 2
This item is for the provision of �" diameter galvanized forged
eyeoolts at each of the four corners on both of the two
smaller roof hatches. These eyebolts are required so that
the hatches can be removed by attaching cables to the eyebolts
for removal by a hoist. The eye bolts were shown only as four
small "tick" marks on the corners of the roof hatches in "roof
plan 1" on contract drawing A-2. The architect neglecteu to
label the "tick" marks. The eye bolts were also not included in
the project specifications.
by letter dated November 5, 1984, NNTB requested Fluor to provide
the eyebolts. By letter dated February 20, 1985, Fluor forwarded
tfieir additional costs for the eye bolts, including installation.
Item No. 3
This item is for the extra labor involved in cutting and rewelding
the perimeter steel angle in the two small removeable roof hatches.
Contract Urawing A-2 calls out the overall width of the two
smaller roof hatches to be 6'-6" and ttie roof hatches were also
drawn to scale at 6'-6". The perimeter roof hatch steel was
fabricated in the shop based on the 6'-6" dimension. After
arrival on the site it was determined that the 6'-0" dimension
was in error and that thz overaii roor hatch dimension should
have been noted as 5'-�". This error required Fluor to field
cut and reweld the perimeter steel anyles for both roof fiatches.
by letter dated November 13, 1984, HNTB requested Fluor to make
;he necessa ry changes to the roof hatch steel. 6y letter dated
Fc�ruary 20, 1985> Fluor forwarded their additional costs for
the steel revision.
Item No. 4
This item is for the furnishing and installing of additional
reinforcing steel in two locations. Tfie first location was
for tt�e provision of oversize hook lengths for all horizontal
reinforcement members at [he "T" intersections � all interior
- 19c -

walls on the low service and high service tanks. The longer
than standard hook lengths were required because of the
anticipated pressures when one tank is empty and the
adjacent tank is full. The requirement for the oversize hook
lengths was not called out in the contract documents
necessating the change for an extra. The request for the
oversize hook tengths was made by HPJTB during the shop
drawing review of the reinforcing steel.
The second location requiring reinforcing steel was at the
revised sump pit in the low lift pipe gallery. Previous
change order No. 2 included the plumbing changes required as
a result of the DIHLR review. A purtion oT the review
required the change in the sump pump system from simplex to
duplex. This change necessitated a much larger sump pit which
required extra steel both around and below the pit due to the
increase in size of the opening in the slab.
Fluor submitted the additional costs for the additional reinforcing
steel by letter dated February 20, 1985.
Item No. 5
This item is for the additioanl labor required to penetrate
the north wall of the existing north reservoir @ the location
where the new 30" diameter D. I. pipe enters the reservoir.
When Fluor Construction Co, commenced with penetration of the
north wall of the reservoir it was found that the wall was
38" thick. The as built drawings for the north reservoir indicate
the wall thickness to be 18" thick. Because of the extreme
thickness of the wall Fluor found it necessary to contract with
a specialty subcontractor to penetrate the wall. In addition
Fluor personnel expended 83 manhours completing the penetration.
HNTki believes that Fluor is entitled to additional compensation
for the wall penetration work because they could not have
anticipated the level oi eftort requircd durirg the bidding phase
of the project. HNTB recommends that the cost of the specialty
subcontractor and 40 hours of Fluor's labor time be authorized
as an extra.
Flcor submitted the additional costs for the extra labor and
equipment required by letter dated February 25, 1985.
item No. 6
This item is for the furnishing and installing of 232 linear
feet of 2" x 2" x 1/8" angle required for installation of
the vertical portion of the metal decking on the east and
west sides of the station. The 2" x 2" x 1/8" steel angles
should have been shown on the structural portion of the
contract drawings but were not included.

Re: Low Lift/High Service Pumping Station
Oshkosh, Wisconsin
Dear Mr. Konrad:
Please find attached four copies of proposed Change Order No. 6
for final approval and processing by the City of Oshkosh.
Proposed Change Order No. 6 consists of four separate items
as described on sheet no. 2 of the change order document.
Also attached for your information in the review of these
change order items is the backup documentation for each item.
Fluor has submitted individual proposals for each of these
items. Each of these proposals have been reviewed by HNTB
and are found to be acceptable in the final amounts as
indicated on the change order documents.
For your use in evaluation of each of these
has been prepared. A brief description of
with the reasons for the change.
Item No. 1
items the folowing summary
each item is given along
This item is for the provision of two additional 20" diameter
90� MJ fittings and all necessary appurtances required to connect
the two new 20" diameter high service discharge lines with the
existing ?4" high service PCCP water main. The existing 24" main
is l�cated at an elevation approximately six feet deeper than the
elevation at which the two new 20" discharge mains exit the new
pump station. The contract plans did not provide indication of
the six foot difference in elevation between the two lines.
As such, tiie contractor could not have included the furnishing
and installation of *he two 90° fittings in his bid. .

RES'OLUTION # 18
Page 2
March 18, 1985
Mr. Gerald F. Konrad
HNTB feels that a better installatio� is being provided
with installation of the two fittings than requiring the
contractor to bend the pipe at each joint in order to
make up the six foot difference in elevation. HNTB requested
Fluor to proceed with the installation of the fittings by
memorandum dated December 13, 1985• By letter dated February
15, 1985, Fluor submitted the cost proposal for the extra
work..
Item No. 2
Item No. 2 is for the provision of insulation over the lz"
sump discharge line running from the new pump station to
existing sanitary manhole on the east side of the filtration
plant. The contact documents cailed for the installation
of the sump line with a minimum of six feet of cover but
without any insulation over the line. Upon commentement
of installation of the line Mr. Melvin Keiffer, superintendent
of the filtration plant,advised that he belived the line
would freeze if installed according to plans because the City
has experienced water main freezes in roadway areas of up
to seven feet in depth. Given this information and the fact
that the flow through the sump line is intermittent it
seemed prudent to provide insulation over the sump line in
order to insure that the line would not freeze.
By letter dated November 15, 1984, HNTB requested Fluor to
furnish the insulation. By letter dated February 25, 1985>
Fluor forwarded the extra costs associated with the
insulation installation.
Item No. 3
This i[em is for the additionai iaour and material necessary to
dewater the existing 30" PCCP intake line running from Millers Bay
to the filtration plant. Dewatering was necessary in order to be
at,le to proceed with the necessary connections to the new pump station.
The contract documents indicated that the contractor could plug the
intake end of the existing 30" intake line in order to make the
required connections between the intake line and the pump statien.
Upon plugging the end of the li�e it was found that leakage into
the line was in excess of 200gpm. It is beieved that there must
be a break in the line tvhere it crosses under the channel
upon exiting Millers Bay. In order to make the required connection5
the contractor I'ad to provide pumps, generators and associated
labor to remove the excess water from the line. All of the pump;ng
had to be done from the Millers Bay end of the intake line.
HtJTB believes that Chis was extra work teyond the s::ope of the
original contract documents. By let�er dated February 25> 1985
Fluor submitted the extra costs for Chis additional work.

Mr. Gerald F. Konrad
Item No. 4
This item is for the additional labor and materials necessary
to reroute the new 30" D.I, pipe connecting the high service
pipes in the new pump station with the existing north
reservoir. The line could not be installed as shown on the
original contract documents because the existing 24" lake
intake mains were found to be located in a position other
than that indicated by existing as built drawings. The
twin intake mains were found to be located almost directly
beneath the existing 24" high service main instead of the
indicated approximate six foot horizontal separation distance.
Actual existing conditions prevented installation of the
new 30" D.I. pipe and alternate route had to be devised
requiring additional pipe materials and associated labor.
By letter of transmittal dated November 30, 1985, HNTB
forwarded the revised routing for the 30" line. By letter
dated February 25, 1985, Fluor forwarded the extra costs
associated with the line rerouting.
If you require any additional information or clarification
of the change order items please do not hesitate to call.
Please return one signed copy each to Fluor Construction Co.
and HNTB upon completion of the change order approval process.
