Task Order No. 17 - Engineering Services for
Phase II - Final Design, Bidding Services,
Services During Construction and Reports for
Aquifer Storage and Recovery Well ASR-2 at
the City of Boynton Beach East Water
Treatment Plant - Amendment No 3 (Design
Modifications and Additional Resident Observer
Services)
Background
Task Order No. 17 - Engineering Services for Phase II - Final Design, Bidding Services,
Services during Construction and Reports for Aquifer Storage and Recovery Well ASR-2 at
the City of Boynton Beach East Water Treatment Plant was approved by the City
Commission on November 19,2002. CH2M HILL (CONSULTANT) has been working on
this project since that time. The original design and bidding services for ASR-2 are
complete and construction is underway.
Drilling of the ASR-2 well is now complete. However following extensive testing of both
ASR-1 and ASR-2 wells under the direction of the CITY, it has been determined that well
interference (water level drawdown) with the existing ASR-1 well is greater than
anticipated. Further, the level of sand being pumped at flow rates in excess of 1,500 GPM
are excessive. These findings necessitate a change in the pumping plant design for both ASR
wells and also removal of the well house over ASR-2 to allow future access to the well for a
drilling rig. Finally the construction period has been further extended due to factors outside
the contractor's control.
These outcomes necessitate the following additional services to be performed by
CH2M HILL:
. Redesign of ASR-2 wellhead layout (removal of well house, relocation of electrical room
and modified noise control)
. Extended services during construction of ASR-2
Redesign of ASR-2 Wellhead Layout
The current ASR well design incorporates a permanent wellhead building which houses the
well head piping, pumping plant and the electrical controls. One of the design objectives at
DFBff017MOD 3V5.DOC
the time was to ensure the variable speed drive set met all noise ordinance requirements,
hence the reason for a building enclosure. However given the uncertainty over the new
ASR well and the inevitable need to be able to relocate a drilling rig over the well, the CITY
has decided to remove the well house. The key elements of the design changes required to
do this include:
. Relocation of the electrical room and all components, to be re-housed in a smaller
NEMA rated enclosure
. Redesign of well pad, to include area for relocated electrical room
. Sound enclosures or baffles to all pumping plant to ensure CITY noise ordinances are
met
. Review and redesign if necessary of all above ground mechanical and pipe work
components to ensure they may be disassembled so as to allow space for a drilling rig
located over the ASR-2 well
Extended Services during Construction
The baseline construction period of 37 weeks has now been extended to a total of 533 days,
or 76.1 weeks as authorized by Field Change Directives (FCD's). Extensions of time for
CH2M HILL construction services to supervise these works were not authorized at the same
time these FCD's were authorized for the contractor. However not all of the FCD time
extensions require full time supervision. In summary, the equivalent full time construction
services required is 54.9 weeks - 21.2 weeks less than the construction period, but 9.3 weeks
greater than currently authorized.
Amendment 3 - Additional Scope of Services for Phase II
Task 1 - Final Design Services
Additional final design services to be performed by the CONSULTANT in this Amendment
3 are as outlined below:
1.3 Redesign of Wellhead Layout. The CONSULTANT shall modify the original ASR
wellhead design so as to allow future access for a drilling rig to perform well maintenance
and a possible change in the well configuration (storage zone). The key elements of the
design changes necessary include:
. Removal of the well house
· Relocation of the electrical room and all components, to be re-housed in a smaller
NEMA rated enclosure
· Redesign of well pad, to include area for relocated electrical room
· Sound enclosures or baffles to all pumping plant to ensure CITY noise ordinances are
met
· Review and redesign if necessary of all above ground mechanical and pipe work
components to ensure they may be disassembled so as to allow space for a drilling rig
located over the ASR-2 well
DFBIT017MOD 3V5.DOC

Construction Drawings. The CONSULTANT will produce the necessary revised civil,
structural, mechanical, instrumentation and electrical construction drawings to show the
changes in design for the ASR well. It is estimated the CONSULTANT will produce
approximately 5 revised construction drawings. Drawings will be produced on II-inch by
17-inch sheets.
Construction Documents. The CONSULTANT will produce an addendum to the ASR-2
construction documents that will include specifications, equipment and instrument lists,
and functional descriptions where needed.
Detailed Design Submittal. The CONSULTANT will provide a 90 percent design submittal
(six copies of documents) for the ASR-2 design modification utilizing the modified well
head design concepts developed with the CITY. The submittal will include the following:
. Draft addendum to technical specifications and construction documents
. 90 percent design drawings addendum (11 x 17 copies)
Detailed Design Review Meeting. Within I-week of the CITY receiving the Detailed Design
Submittal, the CONSULTANT will conduct a 90 percent review meeting with CITY staff to
review the design. The review will consist of one meeting between the CITY and key
members of the CONSULTANT project team. The CONSULTANT will prepare and
distribute written summaries of decisions rendered. The approved written summaries will
serve as the basis for proceeding with the completion of detailed design.
Final Detailed Design Submittal. Based upon the comments agreed upon as a result of the
90 percent review meeting with the CITY, the CONSULTANT will prepare a 100 percent
(final) design submittal for AsR-2 addendum. The submittal will include:
. Five sets of final (100 percent) addendum to technical specifications and construction
documents
. Five sets of final (100 percent) half size addendum drawings (two sets of full size
drawings will also be provided, signed and sealed by the appropriate professional
engmeers.
Task 2 - Bid Phase Services
No additional Bid Phase Services are being provided in this Amendment.
Task 3 . Services during Construction
In addition to services covered under prior Amendments 1 and 2, the following additional
services during construction will be provided under Amendment 3:
3.3 Additional Construction Management and Resident Observation. The CONSULTANT
will provide full time construction management and onsite resident observation services
for an additional lOA weeks. Specific services to be provided are as outlined in the
original task order.

Task 4 - Engineering Report and Operation and Maintenance Manual
Additional services covered under Amendment 1. No additional services are included in
this Amendment 3.
Assumptions
The following assumptions were made for the preparation of this Amendment:
. Construction observation and construction management services are based on
completion of the additional construction by November 30, 2006. If construction is
delayed further due to the CONTRACTOR or the CITY, the CONSULTANT shall be
compensated for additional services beyond this period under a separate addendum to
this authorization.
