Preliminary EOPC
The itemized EOPC from the Engineering Study will be updated and expanded to reflect the
advancement to the Preliminary Design level. The streamlined itemized EOPC will include
updated line items, contingencies, and a construction services cost estimate.

2.08 Sructural Prelirrinary Design
Based on the selected proposed action, detailed structural design will be performed,
including repairs to existing members (if necessary), removal of extraneous existing
members (as needed) and addition of new structural members (as required). CMA Engineers
will provide preliminary design parameters including layout geometry, construction details,
notes, specifications, and supporting design calculations for the selected structural

Existing Condition Plans: These plans will be developed from the information
obtained during the Feasibility Study Phase of the project. These plans will show
existing topographic features, utilities, ROW limits, delineated wetlands, natural
features, Historic features and other visible information needed to construct the
proposed project;
h. Identify the existing utilities, summarize impacts, and determine if utility
impacts are eligible expenditures, and if not, who will pay for impacts to the
existing utilities.
i. Identify the proposed action and why this is the recommended project design.
j. Conceptual level plans of the proposed action in conformance with Section
1.11.
k. The study will summarize required permits for each alternative.
e Discussion of potential impacts related to each alternative (historical,
environmental, utilities, existing structures, Right-of-Way, etc.),
® Conceptual cost estimate, and
® Conceptual level plans for alternatives (typical section, general roll plan).
The Alternatives Analysis process will be used to recommend the most viable and
preferred alternative to advance to Preliminary Design phase. Once a proposed action is
selected by the City, the project can proceed to documenting the process for inclusion in
the final Engineering Study report.

Coordination efforts will take place to identify all utilities within the project. Once
determined, a working directory of contact information, preferred interface, and plan
preference will be determined for ongoing coordination.
Environmenial Documeniation
a. Data Collection
urban design solutions to support the development of a thoughtful, well designed, multi-
modal node downtown that is heavily used, safe, and attractive.
a. Site Reconnaissance
Document and photograph conditions as part of this effort, the following is
anticipated:
« Document observable electrical utilities and acceptable points of connection
e Document valuable assets, linkages, beneficial qualities, and overarching
opportunities
e Document noteworthy existing trees, vegetation, invasive species, etc.
and photo-documented. We will also visually identify/confirm current property uses of
parcels that abut the planned project alignment and identify properties or observed
conditions that may represent potential higher risk conditions.
notential issues and concerns. This meeting will be facilitated by CMA Engineers in
conjunction with City staff and aid in the development of the project purpose and need
statement. An overview plan based on City GIS and/or available aerial imagery will be
prepared for the meeting.
DETAILED PROJECT SCOPE
The scope of the work for the design includes those elements specifically included in the City of
Nashua’s original CMAQ grant application, as approved by the NHDOT to further expand the Heritage
Rail Trail, alleviate congestion on East Hollis Street, and enhance pedestrian/bicycle facilities in one of
