ATTACHMENT B
SCOPE OF WORK
The Engineer has prepared this Contract Agreement for services relative to the
reconfiguration and reconstruction of the City Hall parking lots adjacent to the Nashua
Transit Center Retrofit Project. Currently, the parking lots and their access driveways are
separated. The goal of the redesign is to provide a connection between the parking
areas and combine the driveways for improved functionality and operation. The project
is anticipated to include reconfiguration and design of the parking lots adjacent to City
Hali to improve access and circulation.
The specific work items are further detailed as follows:
FIELD SURVEY AND UPDATED BASEPLAN
GPI will perform a detailed topographic field survey of the southerly parking lot at City
Hall. The detailed topographic survey will include detail necessary to design the
proposed improvements, including but not limited to: surface features including
curbing, drainage and utility surface structures, fences, walls, signs, mailboxes, HVAC
equipment, buildings, foundations, and other ancillary items; spot grade and 1-foot
contours; right of way lines, property lines, and ownership information; and
underground utility information including rims, inverts, and pipe sizes. The Consultant
will also collect additional boundary information to establish accurate right of way and
property lines. Said information gathered during the field survey will be added to the
existing base files being utilized for the Nashua Transit Center Retrofit Project.
PRELIMINARY DESIGN
Upon completion of the additional field survey and preparation of the updated
baseplan, the Consultant will begin preparation of the Preliminary Plans of the parking
lot redesign concept. The preliminary plans will be developed to include reconfigured
parking lot access and driveway consolidation, connectivity between the two existing
parking lots, parking stall layout, pedestrian flow and wheelchair ramps, schematic
drainage and grading plan, and pavement markings. The Preliminary Plans will be
submitted to the City in draft format for review and comment.
FINAL DESIGN
Once the City has reviewed and provided comment on the Preliminary Plans, the Final
Plans will be prepared. The Final Plans will include final engineering design and
calculations, detailed construction plans; grading, drainage, and utility plans; final
pavement markings and signs; detailed wheelchair ramp design; landscape plans; and
construction details. The deliverable will include Final Plans, Specifications and a
construction cost estimate. The Final Plans will be suitable for public bidding and
construction.
