Proposed Amendment to Agreement for Services
for
Booster Tank Upgrades
Project No. 2003 -12
The Agreement for Services between the City of Rohnert Park and Brelje & Race for the Booster
Tank Upgrades Project, dated November 8, 2005, includes multiple tasks including performing a
Needs Assessment, preparation of 50 %, 90% and final construction documents, bidding assistance,
and engineering services during construction. Task 1, the Needs Assessment and attendance at a
subsequent meeting to discuss /confirm the direction and scope of the design effort prior to
commencement of other tasks, has been completed. During the meeting City staff identified desired
changes to the project scope that will require engineering services not in the original scope- Those
additional services required by the revised project scope are as follows:
Additional Services ffaAs 2 t txoughA6
1. Design services associated with modification of the booster pump station at Tank No. L
2. Design services associated with replacement of pressure reducing valves, with new larger
units, and associated piping at Tank Sites 6 and 7.
3. Perform additional research and site investigations at each tank and booster pump site due
to lack of record information on the locations of existing utilities.
4. Perform additional investigations and design services associated with the replacement of the
level sensing device in all tanks_ It has been determined that the type of device varies
throughout the system and will require individual assessments and design solutions.
5. Research and investigate whether reusing the existing booster pumps and motors at Tank
Nos. 3 and 4 is compatible with replacement of the existing fluid drives with VFD drives.
New Task 7
1. Provide SCADA system check -out, trouble - shooting and start - -up services.
2. Update SCADA system graphics layout at the central host station to eliminate currently
erroneous graphics and add to or provide new graphics to reflect booster tank upgrades.
Also, in order to respond to staff questions regarding the adequacy of the existing generators at
Tank Nos. 6 and 7 and requests for tank upgrades at other sites the manhours expended to complete
the Needs Assessment (Task 1) exceeded the original estimate. These items were not included in the
original scope of engineering services - The requested increase to the not -to- exceed compensation
amount also addresses this issue.
The additional services described in this amendment would be performed on a time and material
basis in accordance with the terms set forth in the Agreement for Services. The requested
adjustment to the not -to- exceed compensation amount is $46,000, from $85,000 to $131,000. A
Revised Cost Tabulation and associated Estimated Hours Summary are provided herewith -n the
same format as submitted with the original proposal. The compensation adjustment breaks down as
follows: approximately $3,000 for Task 1 services; additional civil and electrical services estimated at
$22,000 for Tasks 2 through 6 (items 1 — 5 above); and $21,000 for Task 7 (new).
