3. Items for Committee Recommendation to Board
a. Review draft Position Paper to grant bid relief to Bay Pacific Pipelines Inc.;
award a construction contract in the amount of$2,775,589 to Cratus, Inc.,
the second lowest responsive bidder for the South Orinda Sewer
Renovations, Phase 7, District Project 8454; find that the project is exempt
from the California Environmental Quality Act (CEQA); and authorize up to
a 15-percent contingency
Mr. Petit briefly summarized the information included with the agenda
materials pertaining to a request for bid relief and recommendation to
award to the second lowest responsive bidder. The Committee had no
questions.
COMMITTEE ACTION: Recommended Board approval.
b. Review draft Position Paper to authorize the General Manager to amend
an existing professional services agreement with Stantec Consulting
Services, Inc. (Stantec) to increase the contract ceiling from $990,000 to
$1.54 million for design of the Filter Plant and Clearwell Improvements -
Phase 1A, District Project 7361
Mr. Petit provided the Committee with a project update and an overview of
the summarized recommendations included in the agenda packet. Stantec
has provided staff with several recommendations as part of the initial
preliminary design investigations and assessments. Mr. Petit discussed
the various and potential phases, some of which depend on future projects
and the significant impact that a potential water exchange project would
have on the treatment plant.
Of the various filter plant improvement recommendations and diverse
coordination factors, the most critically needed components have been
shifted to a condensed project scope dubbed Phase 1A. These
components are deemed a necessity to maintain a reliable utility water
system and to continue with essential design evaluations, regardless of
whether a water exchange project proceeds. Mr. Petit reviewed the Phase
1A tasks, noting that the Phase IB portion has been kept in the Ten-Year
Capital Improvement Plan (CIP).
Member Pilecki inquired about the tank size needed for recycled water
storage intended under Phase 1A. Mr. Petit answered the size could be
two to three million-gallon tanks for a total capacity of six million gallons of
storage. Whether the storage tank(s) be steel or pre-stressed concrete is
to be determined, should the Clearwell be replaced.

Mr. Petit responded to a mix of questions and provided clarification on
project scope and budget associated with the electrical distribution, efforts
associated with concrete storage and chlorine contact basins, filter
rehabilitation, and anticipated project timing. He stated that funds have
been added to the budget and CIP and are consistent with figures recently
presented at the Board Budget Workshop held in January 2019. It was
further clarified that the recommended Structure 9000 rehabilitation work
will be added to the Outfall Improvements project for expediency.
Moreover, Mr. Petit explained that the filters have never quite worked as
originally intended and the filters are designed for a much larger recycled
water treatment plant. The plan is to assess the worst of the four current
filters to determine the action course to include in the 30% design
submittal. Dedicated chlorine contact basins are recommended and will be
evaluated in the 30% design to determine hydraulic and spatial
requirements relative to the site but will not be implemented as part of
Phase 1A.
Staff aims to report the outcome of the filter study to the Committee in
August 2019 and also request an amendment to the Stantec agreement to
complete the Phase 1A project final design at that time.
Chair Nejedly commented he thought this was a good plan, especially with
respect to a potential water exchange program. Member Pilecki requested
that staff present this item to the Board rather than agendizing it on the
Consent Calendar.
COMMITTEE ACTION: Recommended Board approval and requested
staff give a presentation when the item goes before the full Board.
4. Other Items
a. Receive list of future agenda items
COMMITTEE ACTION: Received the list.
5. Announcements
a. Mr. Petit informed the Committee of an incident that occurred earlier in the
morning involving a contractor employee working onsite as part of the
Plant Operations Building Seismic Upgrades project. While
carrying/moving a wood pallet near the new server room construction
area, the worker walked on aluminum cover plates over a junction
structure and fell into the structure downstream of the primary tanks. Other
contractor employees were able to assist him out. He was given a shower

right away and was subsequently taken to a local hospital for examination.
It is not known how the contractor fell into the structure and a status of the
individual was not readily available at the time of the meeting.
