SCOPE OF WORK
Task 1 — PER Design
• Focus on advancing planning concepts that have been developed in the WRRF
FP (December 2018) and the ABs 1-4 Retrofit Alternatives Analysis task order.
Leading up to the PER Design milestone, elements of the 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 the
proposed design.
o Confirm technology and process decisions documented in the WRRF FP
(December 2018).
o Document compliance with regulatory requirements that pertain to the
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 and geotechnical subconsultants.
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 and hydraulic profile
features in the ABs 1-4 and ABs 9-10 portions of the site, and locating points for
geotechnical investigations. Following completion of the initial field surveys,
Consultant may identify up to 50 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.
