AND
THE CITY OF NASHUA, NEW HAMPSHIRE
DOWNTOWN RIVERFRONT PROJECT
June 9, 2022
The following amends the April 27,2022 Contract between VHB and the City of Nashua for
the above project This Contract Amendment is comprised of
the scope of services described herein and the compensation as detailed in the attached
spreadsheets. This amendment is subject to the Terms and Conditions of the original Agreement.
SCOPE OF SERVICES
This contract amendment specifically covers the final design of improvements along Water
Street as depicted on preliminary design plans dated March 30, 2022. The construction will
include minor roadway and sidewalk geometric modifications, pavement milling and overlay and
new pavement markings and signs to convert Water Street to one-way westbound as approved
by the City. Parallel parking spaces will also be added on the north side of Factory Street. The
work on Water Street will begin at Main Street and end at Factory Street. Minor drainage work is
anticipated to include adding catch basins to collect roadway runoff that would be trapped by
the planned curb extensions. The basins will connect to the existing roadway drainage system.
No system upgrades are included. The work will also include removing traffic signal heads on
Main Street that face the Water Street approach since the road will become one-way away from
Main Street. It is assumed the work will include modifying the existing bridge rail on the north
side of Water Street such that it is pedestrian safe where sidewalk will be added and possibly
beyond if the City expects to close the street for pedestrian events. No work is planned for the
Water Street bridge under this contract and no utility pole relocations are anticipated or
included. No additional traffic analysis is included.
PHASE 3 - FINAL DESIGN
The final design phase will include refinement of the preliminary design. This will include
developing construction pians and specifications for use by the City’s Construction Management
(CM) firm in bringing the project to construction. The following is a description of VHB’s Phase 3
scope of work for the above referenced effort.
