EXHIBIT A
2.0 MG WATER STORAGE TANK AND
WATER TREATMENT PLANT IMPROVEMENTS
ADDENDUM NO. 1 - HIGH SERVICE PUMPING IMPROVEMENTS
INTRODUCTION
The City's water treatment plant currently has three high service pumps (HSP Nos. 5, 6,
and 7) located outside to the south of the existing ground storage water tank. Variable
frequency drives (VFD) manufactured by Eaton were installed on HSPs 5 and 6, but
Eaton has since gone out of business. Thus, the City is experiencing difficulties in
obtaining replacement parts and service for this equipment. The VFD for HSP 5 does
not currently operate as it should and the City has by-passed the VFD such that HSP 5
operates as a constant speed pump. HSP 6 has not been able to operate within its
maximum range, which may be attributed to the pump selection not being compatible
with the VFD. The electric OCV check valve installed on the discharge of HSP 6 also
does not operate as it should.
Hydraulically, HSPs 5, 6, and 7 are designed to pump 3,000 gpm, 3,000 gpm, and 1,500
gpm, respectively. The suction of all three pumps are manifolded by a 24-inch diameter
pipe. The resulting flow velocities through the 24-inch diameter line and the smaller
size of HSP 7 is causing hydraulic problems by "starving" HSP 7 and preventing proper
efficient operation of this pump. The OCV check valve on HSP 7 is also not operating
as it should.
CDM recommends the following improvements to address the above concerns:
■ The existing 24-inch diameter pump suction header is undersized. The size of
this pipe will be increase to provide the desired suction velocities.
■ The VFD on HSP 5, which is currently by-passed, will be removed to provide
proper operation of HSP 5 as a constant speed pump. All other equipment
associated with HSP 5 will remain the same.
■ The VFD on HSP 6 will be replaced, and the pump will be replaced with a 3,000
gpm horizontal split case pump selected specifically for operation with the VFD.
The electric check valve will be removed and replaced with the appropriate slant
disc check valve and isolation butterfly valve combination similar to new HSP 8.
All other equipment associated with HSP 6 will remain the same.

■ A new VFD will be added to HSP 7, and the existing 1,500 gpm pump will be
replaced with a 3,000 gpm horizontal split case pump and motor selected
specifically for operation with the VFD. Suction and discharge piping size will
be increased to the appropriate size for the upgraded pump. The electric check
valve will be removed and replaced with the appropriate slant disc check valve
and isolation butterfly valve combination similar to new HSP 8. Revisions will
be made to the motor control center feeding HSP 7. The existing starter will be
replaced with a circuit breaker sized to feed the new VFD. Wire sizes for feeds
between the new VFD and the new higher horsepower pump will be added along
with the required raceways. Wires between the new VFD and the pump will be
resized to accommodate the larger pump. This may require replacement of
existing raceways between the pump location and the VFD. All other equipment
associated with HSP 7 will remain the same.
■ The clearwell opening where HSP 4 was previously installed will be covered by a
bolted plate. Remaining HSP 4 discharge piping, valves, and fittings will be
removed up to the exterior isolation valve and a blind flange added. The wall
opening will be sealed.
■ A roof canopy, matching that over the new HSPs 8 and 9, will be added over
existing HSPs 5, 6, and 7 as requested by the Broward County Health
Department.
. ■ Upon completion of the above improvements and modifications the exterior
p p P ,
HSP 5 through 9 will be used under normal operation while HSP 1 through 3 will
remain over the clearwell only for back-up operation.
SCOPE OF WORK
The following tasks present the proposed scope of work to be provided by the
CONSULTANT to implement the above improvements as part of the 2.0 MG Storage
Tank project.
Design - The CONSULTANT will undertake the appropriate level of engineering to
design the proposed improvements including a hydraulic analysis of the high service
pumping system. A two -page technical memorandum of the design of these
improvements will be prepared as an amendment to the preliminary design report. The
drawings and specifications will be developed to include the existing HSP
improvements. An updated cost estimate will be prepared upon completion of design.
Design of improvement work other than that listed above will be considered beyond the
scope of this Addendum No. 1 proposal.
0 A-2
ML0304
Permitting/Bidding/Construction - CONSULTANT services during the permitting,
bidding and construction phases are not anticipated to result in any significant additional
level of effort if the proposed improvements are undertaken as one construction project.
It is assumed that the construction period duration will remain the same. A contingency
allowance for services during construction has been included in this proposal to be used
at the City's discretion.
DATA AND ASSISTANCE TO BE PROVIDED BY CITY
The CITY will provide CONSULTANT with available information associated with the
existing equipment not already on file with CONSULTANT. The CITY will review the
updated 90% design documents and will meet with CONSULTANT to discuss the
CITY's review comments.
TIME OF COMPLETION
The CONSULTANT will undertake the design work and incorporate the proposed
improvements into the current 90% design documents within 60 calendar days of
authorization to proceed with Addendum No. 1. All other time frames will remain the
same as in the original scope of work for the 2.0 MG Storage Tank Project.
0 PAYMENT AND COMPENSATION
The total not to exceed fee for this proposed Addendum No. 1 work, based on the level
of effort presented in Attachments A and B, is $34,677. This fee includes a lump sum of
$925 for non -salary other direct costs. Monthly invoices will be prepared based on
actual labor hours times the prevailing hourly rate plus non -salary other direct costs and
outside professional services.
