This office has reviewed your correspondence dated October 2 1996 on the proposed
contract modification (PCM-014 ) concerning the revising the alignment of the 2300 volt
electrical feeder ducts between the North Holly WTP High Service Pump Station medium
voltage switchgear and transformers T1, T2 (adjacent to North Holly Chemical Building)
and T3 (at northeast corner of North Holly Chlorine Building). Part of the realignment
allowed the use of existing duct bank for a portion of the feeder run to transformer T3.
The other realignment for the feeder run to transformers T1 & T2, avoids a conflict 'with
Sedimentation Basin #3. This realignments lowered the construction cost s for the feeder
ducts. The Water Department agrees with your recommendation that the contractor
proposed credit of$1,34.74 for these changes should be accepted as the credit proposed is
fair and reasonable.
Therefore, this office will recommend to the City Council (and/or the City Manager's
Office), the approval and acceptance of this credit in the form of a change order to be

INTER-OFFICE CORRESPONDENCE

FROM: David Townsend, Facilities Engineer
Water Department
DATE: October 16, 1996
SUBJECT: PCM-022: North Holly Safety Related Improvements
North and South Holly Water Treatment Plant
Backwash Facilities Modification
and Chlorine and Ammonia Rehabilitation
Project Nos. PW77-060770500020 & PW77-060770500030
This office has reviewed your correspondence dated October 15,1996 on the proposed
contract modification (PCM-022 ) concerning the three safety related items for the North
Holly Water Treatment Plant which where requested by the plant.
Item 1. Galvanized Steel Stairway at North Holly Raw Water No. 1 Valve Vault.
The requested that a stairway be installed at the RW41 Valve Vault. Currently assess is
limited to the unimproved road at the top of the levee making assess is difficult and
dangerous during wet weather. The Stairway will allow assess from the a lower parking
area. The Water Department agrees with your recommendation that the contractor price
proposal of $8,138.88 for this item should be accepted as the cost provided is fair and
reasonable.
Item 2. Modify North Holly Raw Water 2 & 3 Post Chemical Application Vault
Lid. Current assess is through a standard 24-inch manhole rim (and cover) using a ladder.
This is to small to allow assess for personnel when using an airpack. The plant has
requested that the vault lid be modified to install a larger aluminum (Bilco) hatch and to
install a safety ladder in the vault. The Water Department agrees with your
recommendation that the contractor price proposal of $5,375.89 for this item should be
accepted as the cost provided is fair and reasonable.
Item 3. Remove Portion above of North Holly Sedimentation Basin 41 Wall. The
plant requested that a portion of the North Holly Sedimentation Basin 41 Wall be
removed (above elevation 551.0) to allow visual inspection of the chemical storage area
from the road. The Water Department agrees with your recommendation that the
contractor price proposal of $2,714.32 for this item should be accepted as the cost
provided is fair and reasonable.
The Water Department understands that total cost of all three items is $16,229.06.
Further, the Water Department understands that while this PCM does not include
additional contract time, should it not be approved before December 6, 1996, additional
costs (overhead costs) and additional contract time may be required.

Item Z.Modify the North Holly Raw 2&3 Post Cliemical Application Vault l.id
Item 3;Remove the wall above D 551.0 on the east side of theabandoned
sedimentation basin
Dear Mr.Towmend:
Transmitted herewith please find a copy of Cajun's Octol><r 8, 1996, price propor,a for the
referenced PCM. This PCM consists of three safety, related items for the North Holly plant
which have been requested by the plant staff.
Item 1 provides new stairs at the North Holly Raw No. 1 valve vault.. Currently access is
limited to the unimproved road on top of the levee which has traffic ability' problems during
wet weather or up a steep grass slope from the lower parking area.
Item 2 modifies the existing access manhole on top of the North Holly Raw 2&3 Post Chemical
Application Vault to be an access hatth and ladder. Currently there is no ladder into the vault
and the manhole is too small to enter easily when personnel are wearing an air pack.
Item 3 lowers the east wall of the existing North Holly abandoned sedimentation basin by
deleting the upper wall section. Removal of this wall improves plant visibility into the new
chemical storage area.
We have reviewed the price proposal and recommend the City authorize this additional work
and issue a Change Order.The costs associated with these items are$ 8,138.88,$5,375.89, and$
2,714.32;the total cost of all three items is S 16,229.06.
Mr.David Townsend

No additional Contract Time has been requested if approval is granted by the City by
December 6,1996.Cajun has advised us that due to lead time on the Item 1 stairs and the Item 2
hatch and ladder that they will need additional Contract Time and overhead costs as these
items will become critical path activities if approval is received after December 6th. We concur
with Cajuns assessment of their schedule. Please advise if the Nater Department desires this
PCM, or any portions of it, to be incorporated into a Change Order.
