references in the specifications will be reviewed and items which are no longer applicable to the project
will be removed, struck out or otherwise noted to be “not in contract’. An updated “front end” will be
prepared, to include an updated bid form, bid dates, measurement and payment, and summary of work
to reflect the revised project.
The updated “Phase 2” bid package will include the previously designed work at the following stations:
Northgate, Blackstone, Santerre, Spalding, Harris Preserve, Maurice, and Bridge Street. Designers will
review and update the contract documents as needed for the following disciplines:
Civil
Architectural
Structural
Mechanical
HVAC
Plumbing
Electrical
Instrumentation & Controls
As part of the updates to the design documents, we will verify that the existing designs meet current
building code. New Hampshire changed the version of the International Building Code used statewide in
2019. The 2018 design for the buildings at Northgate, Blackstone & Santerre pump stations will be
reviewed against the current code for wind load and other electrical and structural code requirements to
verify compliance.
Design of the force main replacement at Northgate will be based on geotechnical data obtained during
the previous design work. Brierly Associates will review the previous design and incorporate any updates
to the design as necessary.
The design of Marshall Street Pump Station will be revised to abandon the pump station and replace it
with a new PVC gravity sewer. These modifications are dependent on the results of a hydraulic model
and flow monitoring being performed by others. This work will be included as a bid alternate to the
contract.
At Bridge Street CSO station, the incoming service will be modified per the City’s comments received in
December 2020, as well as a manual transfer switch and portable generator connection. Design of a
new switchgear, or permanently installed generator/automatic transfer switch is not included in the
design efforts at this time. The City may wish to upgrade these components of the facility when the
incoming electrical service is upgraded.
After the revised Contract documents have been prepared, the documents will be submitted to NHDES
for review and approval.
Bidding Services
Bidding service assistance will be provided to the City on an “as-needed” basis and as directed by the
City. This assistance could take the form of response to bidder questions or attendance at a pre-bid
meeting. The City of Nashua will be responsible for all advertising for the project, opening of bids, and
bid evaluation.
