not violate the “0.00 ft rise” flood level criteria. Use the river model to determine
velocity, scour and erosion potential as parameters in designing the final
embankment surface treatment(s}.

Permitting Support

TTG will provide permitting support to the City in the implementation of permit terms and
conditions within its final engineering design.

ADDITIONAL SERVICES

The following are considered additional services that are not considered final engineering
design; but, will be needed to complete the final engineering phase of this project:

Final Engineering Design Proposal 05-11-22

TURNER
GROUP

A.1___ Geotechnical Analyses & Recommendations

TTG intends to subcontract the geotechnical engineering work to SLR International
(formerly HTE Northeast, Inc.) out of Bedford, NH. TTG has performed many similar
water/land projects with SLR support.

SLR will provide reasonably conservative geotechnical analyses and recommendations for
the TTG final design structures. It is TTG’s understanding that prior to construction, the City
will obtain (at the direction and approval of TTG/SLR) new subsurface (land and water)
borings. Data from the borings will be used to confirm; or adjust SLR foundation
recommendations,

If the TTG designs change, the City will be notified and a scope and budget for any redesigns
provided.

A.2 — Spot Field {Instrument) Surveys

Certain design details (Bicentennial Park — 4 Water Street elevated boardwalk interface,
new retaining wall under the expanded deck where 4 Water Street's elevated boardwalk
meets Renaissance Park/dock gangway, the substation screening foundation, etc.) will
require more “in-situ” ground elevation points and existing structure feature Information.
TTG will be requesting 2 to 3 days of HSI field survey crew time to obtain this information
for TTG.

A.3 — Proiect Progress Meetings

In addition to the design coordination meetings identified in the scope for “basic” final
engineering design services, TTG has estimated 12 project progress meetings with the City
and Its project representatives, to present ongoing design results, discuss budget/schedule
status, and identify potential problems. We expect these meetings would be 1 to 2 hours in
length and involve two TTG project staff to prepare, attend/present, and provide certain
meeting follow-up.

A.4 ~ Construction Manager {CM) Coordination

TTG understands the City plans on utilizing a CM to assist it in implementing the Riverfront
Project. It Is likely the CM will be issuing RFls, Requests for Clarifications, and doing value
engineering assessments of the TTG final engineering design. TTG recognizes that time will
need to be allocated to coordinate with the City CM; but the extent and scope is
undefinable at this time.

Our services for this project will be provided in accordance with the attached “Standard
Conditions for Engagement” dated January 1, 2022.
