therefore the design team will not be required to address such comments.
• Digester operating points to be integrated into the facility's RSView system are limited to
temperature and level for Digesters 1 and 2 only. A total of four analog inputs will thus be
incorporated into the SCADA system HMI screens
• No process control logic modifications are anticipated. That is, Integration work Is limited to
presentation of the new points on the HMI Screens. Changes to PLC logic other than that
necessary to scale the points for presentation at the HMI are not included.
• Local I/O cabinet for monitoring digester operations has sufficient spare analog input points to
accommodate the additional inputs.
• Additional conduit and wire necessary for circuiting the analog variables will be implemented in

1.3.1,4 Subtask 1.4 — Document Review and Safety Plan
Before the initiation of corrosion assessment field work, V&A will review as -built drawings and prepare a
Safety Plan outlining the procedures and specific hazards that will be encountered while conducting the
condition assessment. An electronic copy draft will be provided to the City for review. Comments will be
Incorporated and a final electronic copy submitted. V&A's documentation regarding health and safety
training of its staff will be submitted with the Safety Plan.
1,3.1.5 Subtask 1.5 — Corrosion Repair Assessment
The following assessment methods will be used to evaluate the structures and their appurtenances. It
should be noted that the assessment of the structures will be limited to safely accessible areas. It is
assumed that the assessment will be conducted during four separate mobilizations.
Concrete pH Samples: Perform pH tests on the surfaces of the structures. The pH of concrete can
substantiate the levels of concrete corrosion attack prevalent within the structures. Samples will only be
taken where bare concrete is accessible, a sound coating or lining will not be removed to take a sample.
Reinforcing Steel Measurements: Measure the thickness of concrete protecting the reinforcing steel
using SPR (surface penetrating radar). The SPR will also be used to verify the spacing of the reinforcing
steel in the walls. The measurements will be taken on the walkways of the structures and up to two (2)
0.5 -foot wide by 2 -foot long areas of the influent/effluent channels.
Portable Zoom Camera: A portable zoom camera will be used on the two Aeration Basin Influent
Channels if an entry is not possible.
Penetration Measurements: Perform concrete penetration measurements at two (2) key locations in
each structure, as accessed from topside, to find approximate depth to sound concrete. The concrete
penetration measurements will be taken by striking the concrete with a handheld chipping hammer and
measuring the maximum depth to sound concrete. Penetration measurements will only be taken where
bare concrete is accessible, a sound coating or lining will not be removed to perform the test.
Sounding: Conduct sounding evaluation on the concrete surfaces of the structures. Sounding a surface
refers to tapping the structure surfaces with a chipping hammer and listening for discontinuities within
the surface, Locations for sounding evaluation will be selected on the walls and slabs of the structures at
the discretion of the evaluator conducting the assessment.

SUBJECT: White Slough WPCF 2016 Repair and Miscellaneous Improvements Project
Dear Mr. Swim ley:
As you are aware, changes during the construction of the subject project have impacted the services
that West Yost Associates (West Yost) and our subconsultants are providing. These changes were
made to improve the reliability of the treatment plant, and we have endeavored to complete our
services within our original staffing budgets, however we have concluded that this is not feasible.
Following are descriptions of these changes and their impacts to our services, and estimates of the
additional budget necessary to complete our services on this project.
ADDITIONAL SERVICES
While some contract change orders during construction were anticipated (the additional repairs to
the headworks area and repairs to the industrial pipeline are examples), this project has included a
number of major changes that significantly impact the duration of construction and our level of
effort. These improvements are briefly described below.
• Storage Pond Level Monitoring — This change order involves constructing
improvements necessary to: (a) monitor water levels in storage ponds 1, 2, 3 and 4;
and (b) transmit this information to an existing local control panel at the pond
recirculation pump station. West Yost has completed the design of these
improvements, obtained a proposal from the Contractor to construct the
improvements, and processed a change order for this work. Future work by
West Yost includes review of contractor's submittals, construction
management/inspection, programming necessary to incorporate monitoring data into
the plant's SCADA system, and record drawing preparation.
• Digester Temperature Monitoring — This potential change order involved
constructing improvements necessary to: (a) monitor temperatures of sludge in
recirculation lines from Digesters 1, 2, 3, and 4: and (b) transmit this information to
an existing local control panel in the digester control building. West Yost has
completed the design of these improvements, obtained a proposal from the Contractor
to construct the improvements, and processed a change order for this work. No
additional services are anticipated.

• Digester No, 3 Cleaning and Coating — This work involved two change orders, one
to clean the digester and the second to demolish the existing mixing system and coat
the interior cover of the digester. West Yost has inspected the digester cover interior,
and has prepared documents necessary to obtain proposals from the Contractor to
complete the work. Future work by West Yost includes a review of contractor's
proposal and submittals, and construction management/inspection.
• Main Aeration Pipe — Leaks have been observed in the existing 24 -inch -diameter
steel Air Main pipe between the foundation of the blower building and exterior wall
of the aeration basin pipe gallery. West Yost has been asked to implement the
replacement of this pipe by change order. West Yost has completed a preliminary
design of these improvements, however field explorations are necessary to complete
the design. Future work by West Yost includes completing the design, reviewing
contractor's submittals, construction management/inspection, and record
drawing preparation.
SCHEDULE
Originally, the contract documents for these improvements required construction to be completed
within 110 calendar days (by the end of October 2016), and our estimate of the effort required to
perform inspection and construction management services was based on this schedule. As a result
of the additional improvements described above, construction is expected to continue through the
later part of January 2017, take a three-month hiatus, and then continue through May and
June 2017 (a total active duration of about 260 calendar days).
ADDITIONAL BUDGET REQUESTED
Table 1 summarizes our estimate of the additional costs that West Yost and our subcontractor will
incur as a result of the additional services and construction duration described above.
