Materials-testing will be in accordance with the Quality Assurance & Materials Testing
requirements of the NHDOT’s LPA Manual. This effort will require the addition of an
independent testing laboratory, which would be carried either as an allowance under our
Construction Phase Services Contract, as allowance in the Contractor’s bid, or under a
separate contract with the City.
A. SCOPE ASSUMPTIONS
° All public meetings will be attended by two CMA Engineers personnel.
e Geotechnical investigation is not included in the current scope. If the City deems it
necessary going forward, it will be added via a contract amendment.
e Alteration of Terrain, Wetland, or Shoreland Protection Act permitting is not included
in the current scope.
@
Legal and/or appraisal support for the development of any temporary or permanent
easements is not anticipated or in the current scope. If needed, it will be added via a
contract amendment.
e Traffic related data collection is not included in this scope. If additional data is needed
beyond what is provided from the City, a Contract Amendment will be needed.
@ One submission of each of the Engineering Study and Preliminary Plans is provided for
in the scope. It is assumed that review comments from each will be incorporated in
the submittal for the subsequent design phase. Resubmittals (if required) are not
included in the current scope.
2 The Final Design phase includes two (2) submittals: Draft PS&E Plans and Final PS&E
Plans. Any additional submissions within the Final Design phase are not included in the
current scope.
e Construction Phase services are listed for reference, but not included as part of this
contract. It is expected that these services will be negotiated as part of future contract
amendment as the work is better defined.
e This scope and fee estimate is predicted on a 10-month contract duration. Extended
contract duration will necessitate a corresponding increase in engineering fees for
Project Management (coordination with NHDOT/City staff and subconsultants,
monthly status reports and invoices).
e Until a detailed condition assessment of the bridge is performed, the extent of any
section loss or corrosion is unknown. Design, detailing, and specification of surface
protection/anti-corrosion treatments for the existing structure are not included in this
scope and fee.
e At the bridge structure, evaluation of substructure elements will be limited to visual
inspection of exposed portions. Subsurface exploration to determine exact size and
condition of substructure elements is not included in this scope. For the purpose of
design, it will be assumed that the substructure elements are in serviceable condition
and capable of carrying the proposed loads, unless otherwise observed.
® All assumptions and limitations expressed in subconsultant’s scopes of work shall be
considered part of this scope and apply to CMA Engineers.
