be adjusted as part of Hoyle, Tanner's company-wide salaries for cost of living and merit
increases and shall not be limited to employees working on this project.
e Billing for cost-plus-fixed fee type projects will be in accordance with the roster of
employees and direct labor rates on file with NHDOT at the date of the Agreement and as
amended during the duration of the Agreement (see assumption above). Direct salary
rates will be capped at the NHDOT maximum of $60.00 per hour.
e A kayak launch at the proposed pedestrian bridge site will be investigated as part of the
Feasibility Study. At the time of the preparation of this proposal, it has not been
determined if the launch will be incorporated into the project, therefore our proposal does
not include final design of this future project.
e Amaximum of two trail alignments will be presented in the Feasibility Study. An alignment
altemative approximately 450 feet in length will be evaluated on either side of Everett
Street.
e Bridge types to be studied and presented in the Feasibility Study are assumed to be limited
to:
o Prefabricated Steel Truss
o Steel Stringer / Concrete Deck
o Glulam Stringer / Glulam Deck
e CADD drawings to be included in the Feasibility Study indude a Trail Plan, a Typical Section
of each bridge alternative, and a General Plan and Elevation (Bridge) of the preferred
alternative, Trail plans will be developed at 1” = 20’.
e A hydrologic / hydraulic analysis of the proposed bridge will not be required..
e The design will be based upon our approved Feasibility Study for the project.
e Rectangular Rapid Flash Beacons (RRFB) (2 total) will be designed for the proposed
crossing of Ledge Street. These designs will include lighting design in accordance with
the “Informational Report on Lighting Design for Midblock Crosswalks”, publication
number FHWA-HRT-08-053, dated April 2008. As part of this design, a photometric plan
will be prepared and submitted as part of each project submission. No other lighting
design will be required for the project.
e No additional historic or archaeological studies or investigations will be required by the
NHDOT Cultural Resources Committee.
e The project will be classified as a “Non-Significant” project by the NHDOT Traffic Control
Committee (TCC) and no further meetings or paperwork will be required by the TCC.
e The preferred alternative for the pedestrian bridge is unknown as of the preparation of
this contract. For purposes of establishing effort for this contract we have assumed that
the new pedestrian bridge will be a single span, steel stringer bridge with concrete deck
on concrete spread footings with helical pile supports. The proposed trail connection
between the Heritage Rail Trail and the proposed pedestrian bridge is anticipated to be
approximately 450 feet in length, including an ADA compliant ramp at the rail trail and the
