EXHIBIT B: SCOPE OF WORK
I. Prepare Preliminary Design Report for Screening Upgrade at Wet Weather Flows
Facility
A. Preliminary workshop. ENGINEER shall attend a preliminary workshop with
OWNER to review the work plan for the upgrade project, and solicit input on key
issues, ancillary improvements, and potential site visits to inspect existing
installations. Brainstorm on options, and identify the preferred alternatives for
detailed evaluation.
Develop base plans and collect site data. ENGINEER shall develop base plans
for construction documents using existing record drawing information
supplemented by detailed field measurements. This will primarily focus on the
depth and dimensions of the wet weather diversion structure, influent channels,
and influent wet well. Assume | site visit for field measurements by ENGINEER
with 2-person team.
Prepare and Issue Technical Memorandum (TM)
1. Evaluate design requirements for screens, including modifications to
existing influent channel and first floor level. Evaluate suitable
manufacturers and secure initial budgetary quotes.
a. Arrange and attend up to 1 days of field trips with OWNER staff to
comparable mstallations. Budget for up to 1 OWNER staff and 1
ENGINEER staff for flight and overnight accommodations related
to site visits. ENGINEER shall prepare TM summarizing findings
of site visit(s).
2. Evaluate modifications to existing wash press installation to account for
new screens and improve overall reliability.
3. Evaluate modifications to monorail system to account for new screens.
4, Evaluate options to improve access to influent channel level from first
floor including ladders, safety davit crane for personnel removal, and
supplemental ventilation.
5. Each of the ENGINEER’s building design disciplines shall inspect
existing facilities and prepare TM’s summarizing the anticipated
improvements as follows:
a. Architectural issues will be limited to requirements for allowing
the screens to be installed through roof either through temporary
opening and repair to roofing or through new permanent hatch.
Summarize findings in draft TM.
