specifications. Bid Documents will be issued subsequent to resolution of City Public
Works and Building Department comments on the Final Design Submittal. Bid phase
support will be provided to the City including answering technical questions from
contractors/vendors and review of contract addenda (if needed).
Task 1 — PER Design
• Focus on advancing planning concepts that have been developed in the FP
(December 2018). Leading up to the PER Design milestone, elements of the
Task Order 11147 Digester 6 Design Page 1 of 22
Brown and Caldwell
work will be discussed and submitted separately for review by the City to confirm
design direction (e.g., Coordination Meetings).
• Document the basis for final design for the Project scope of work to achieve the
following objectives:
o Form the basis for detailed design and preparation of contract documents and
obtain City approval on general arrangement and direction of proposed
design.
o Confirm technology and process decisions documented in the FP(December
2018).
o Document compliance with regulatory requirements that pertain to design of
sewage treatment facilities.
o Serve as a vehicle for City input to the preliminary design effort.
o Use information provided by the survey.
o Review code compliance.
o Update construction cost estimates.
1 .1 Topographic Survey and Base Mapping Support
• Review the existing base maps and as-built drawings that have been
prepared for previous upgrade projects at the site and conduct additional
surface/subsurface field surveys in the vicinity of proposed new facilities and
improvements for the Project. Combine existing and new base map
information to create a complete file of the mapping covering the areas
affected by the proposed Project improvements.
• Surveying services will be contracted directly by the City and will consist of
reviewing the base map and as-built documentation for the site, obtaining
new field survey data, and combining existing/new information on the City's
WRRF coordinate system and datum. The field survey will be coordinated at
two different points during the PER Design period. Initial activities will focus
on gathering data on readily visible above ground facilities not already
depicted on the existing topographic map, obtaining surface topography in
the Digester No. 6 portion of the site, and locating points for geotechnical
investigations. Following completion of the initial field surveys, Consultant will
identify up to 200 points including both surface and subsurface (rim to invert
type measurements) requiring additional accuracy for Final Design phase
tasks. It is assumed that potholing existing buried utilities will not be required
for this task.

where geotechnical conditions have not been explored previously, and
develop design and construction recommendations related to geotechnical
conditions in the vicinity of the proposed new facilities.
• Geotechnical services will be contracted directly by the City and will consist of
reviewing the results of the soils investigation performed during execution of
the previous design efforts for the Project and conducting a geologic
reconnaissance of the Project area to collect information on the general
nature and physical features of the Project site. Subsurface soil conditions in
the vicinity of Digester No. 6 will be further explored by advancing exploratory
borings to depths determined jointly by City, Consultant, and Geotechnical
Engineer. If the conditions in these initial borings are drastically different from
each other or different from conditions revealed in previous borings at the
Project site, additional exploration would be needed. At each boring location,
representative samples of the various soils encountered will be obtained and
a detailed log of each exploration will be maintained. Representative soil
samples will be delivered to a laboratory for further evaluation and testing
including determination of moisture content (up to four tests) and grain size
distribution (up to four tests). Following completion of the field and laboratory
testing programs, certain geotechnical engineering analyses will be
performed. Descriptions of surface and subsurface conditions observed,
results of the engineering analyses, and design-level geotechnical
engineering recommendations pertaining to the following items will be
summarized in a geotechnical report:
