Michael F.Thuss, P.E.Dear Mr. Thuss:
2011.07.21 09:17:45 -05'00'
As requested at the June 30, 2011 construction meeting. W.L. Hailey & Company, Inc. (W L. Hailey)
submitted the enclosed July 13,2011 letter to provide additional cost infonnation regarding the
previous response to CPR #3.
As stated in the July 13letter,W.L. Haileyhas proposed two options in response to CPR#3. One
option proposes no change in the contract amount for deleting the polyethylene wrap on ductile iron
pipe installed under water. This is based on the contention by W.L. Hailey that additional costs were
incurred during installation of rock bolts at the under water pipe manifold thrust block. Note: At the
time of rock bolt installationat the manifold thrustblock, W.L. Hailey did not makea claimfor
additional costs, in order to expedite the construction.
Based on the cost informationrecentlyprovided byW.L. Hailey,the additional cost associatedwith
rock bolt installation to date ($63,784.32) exceeds the credit amount for deleting the polyethylene
wrap, which is estimated to be approximately $52,000 ($27.00 I LF x approximately 1,930 LF). In
addition, it is possible that futureinstallation of concretereaction blocks from approximatelyStations
14+62to 17+04will alsorequire additional lengths ofrock bolts, which would addto the $63,784.32
cost mentioned above.
Regarding whether the additional costs for rock bolt installation are justified, Jacobs Engineering
Group, Inc. (Jacobs) reviewed the contract documents and has the following comments:
I. Sheets S-l and S-2 of the drawings show two options for construction ofthe manifold thrust
block (drilled piers with smaller concrete thrust block, and larger gravity thrust block,
respectively). Note 1 on Sheet S-1 requires that the listed pier design values be confirmed by
a Registered GeotechnicalEngineer hired by the Contractor before construction starts, if the
drilled pier option is used. Note 8 on Sheet S-I and Note 8 on Sheet S-2 allow the Contractor
to submit alternative manifold thrust block designs. Note 8 also requires the Contractor to
hire a Geotechnical Engineer to evaluate and provide foundation design recommendationsfor
alternate thrust block designs. W.L. Hailey elected to submit an alternative design using rock
bolts, and provided an alternative foundation designed by a Geotechnical Engineer.
2. Paragraph 4.2.2.3.C.2. of specification Section00800 addresses "Differing Subsurface or
Physical Conditions" and states: "Contractor shall not be entitled to any adjustment in the
Contract Price or Contract Times if: ... b. the existence of such condition could reasonably

test. or sbJdy of the Site and contiguous areas required by the Bidding Requitementsor
Contract Doaunarts to be conductedby or for Contractorprior to Contractor's makingsuch
final corumilmmt.It
Based on the above. an argument could be made that W.L. Hailey should be responsible for the
additional costs associated with rock bolt installation. However.the above mentionedlanguagefrom
Paragraph 4.2.2.3.C2 is standard in the SupplementalGeneral Conditions. and an argument could
also be made by W.L.Hailey 1bat the standard language was not intended to apply to the
circumstances of this specific project (i.e.•additionalexamination,investigation, exploration,etc.
wouldhave required soil borings in water up to approximately 80 feet deep).
Also. in addition to other reasons, the alternative designs mentioned in Item 1 above were submitted
in good faithby W.L.llailey in order toreducesome of therisks associated with the overallproject.
Consequently.the alternativedesignsresulted in certain benefitsto both W.L. Hailey and BCRUA.
An argumentcould also be made that the methodologyusedby W.L. Hailey to calculate the
additional costs associated with rock bolt installationresults inunnecessarilyhigher costs,which
could be reducedsomewhat. However,it is obviousthat the actualconditionsencountereddming
instaIJation of rockbolts at the manifold thrust block did require additional labor, materials and
equipment,for whichW.L.Hailey did not originallyanticipate. Consideringthe possibilitythat
similar conditions may be encountered duringinstallation ofrockbolts for the reactionblocksthatare
still to be constructed, it is the opinion of Jacobsthat the ''no costchange" proposalby W.L.Haileyis
fair and reasonable. andwe hereby recommend its acceptance.
If thisrecommendationmeets with the approval ofBCRUA,a changeorder will be prepared to
document deletion of tile polyethylenewrapat no changein contractamount. If youwouldliketo
discuss this. or need any additional information. please call.
Sincerely.

Attention: Glenn Bridges and Michael Thuss:
Dear Glenn and Michael:
The purpose of this letter is to explain how I derived at the costs/credits mentioned in the letter written on
June 16, 2011, regarding deleting the pipe wrap from the scope of work, and dealing with the extra
overburden/rubble at the manifold thrust block. As you may recall, I proposed two optIons: One option
was/is to callthe deletion of the pipe wrap from the scope of work,and the expenses of dealing with the
extra overburden an even swap, and carry on aswe are. In other words, we offer no credit from the
deletion of the pipe wrap, and we charge nothing extra for drilling through the extra overburden, neither at
the manifold thrust block, nor (if applicable) at the twelve thrust blocks of the 200' radius curve. The other
option was/is to offer a credit of$27.oo/foot for the deletion of the pipe wrap coupled with a charge of
$63,784.32 for the extra costs encountered dealing with the extra overburden at the manifold thrust block,
plus, possibly more charges for whatever expensesare encountered if extra overburden exists at the twelve
thrust blocks of Curve#2,
This is how I derived at the amount of $27.00/foot credit for the deletion of the pipe wrap. When I wrote
the letter on June 16, I estimated that it would take about ten minutes (or so) per pipe joint on top to install
the poly-wrap on the pipe,andalsoabout ten minutes (or so)on the bottom for the diver to dealwith 1t.1
Assuming eachpipe joint to beapproximately18feet long,and usingthe samehourly Jobcosttable that
wasprovidedwith CPR #1 (which,job costtable, isalsoattached herewith) I concludedthe following:
$l,328.84/hour x 20 minutes/joint x 1 hour/60 minutes x 1joint/18 ft. =$24.61/ft.
Toaccountfor the "or 50-5", andto makethe value a niceeven numberI dedded to see if @27.00!footwas
reasonable. At $27.00/foot I determined:
$27.CO/ft. x 18 ft'/joint xl hour/$1328.84 x 60 minutes/1 hour =21.94 minutes/joint.
I wassatisfiedwith this number.
(Thematerialcostfor the portion of the poly-wrap usedon the lakebottom isapproximately $2.08/ft. But
sincewe are probablynot goingto be ableto return this material for credit, andsincethe amount isnot
that much,I did not Includeit Inthe amount of the credit.)
Concerning the $63,784.32 charge for the extra drilling at the manifold, I derivedat this numberthis way:
3(extra)hours/anchor x16anchorsx$1328.84/hour =$63,784.32 (extra).
Therewere alsoextra material costs involvedwith this/but I did not includethem either. I should have.
Anyway,this ishow I derivedat the givenfigures. If necessary we can discuss this more at tomorrows
meeting.
Sincerely,
Steven E. Mainord
1)now realize that I made a mistake inthatI should have only Included theten minutes (orsolon thebottom. On top,
theten minutes would have been done whilewere waiting onthe divers, and thus in reality would have added
nothing to the duration ofthejob. But anyway •..
1 1-3/8" 150ksl Williams AII·Thread Rock Anchors runabout$6.83/foot. We used an extra 240feetatthe manifold
alone. Couplings are $17.63 each. We used at least 16 extra atthe manifold. Grout Is $35.26/bag. Butwe probably
only used about22or 23 extra bags atthe manIfold dueto theextra overburden. This alltotalsup to $2,732.26, using
23 bags of grout.
