Because the scope of this effort is unknown, for budgeting purposes, we assume up to 62 hours
will be required to complete the post-application coordination. If required due to an agency
request not anticipated, reallocation or an adjustment to the original Scope of Services and fee
may be necessary if the follow-up services are more than the initial allocation.

Task 12. Archaeological Survey and Coordination (Optional)

Early coordination with NHDHR suggests that archaeological field surveys are likely not
necessary. However, recognizing that some historical archaeological deposits may be affected,
under this task we propose to carry an allowance of $5,000 for an archaeological subconsultant

if the NHDHR response to the RPR requests any such work.

Task 13. Soil & Groundwater Desktop Study

VHB will conduct a review of the searchable online environmental database (“OneStop”)
maintained by the NHDES, to identify contaminant sources with the potential to significantly
impact the project. The database will be queried to select State- regulated sites located within
1,000 feet of the estimated project limits of disturbance (i.e., study area). For these sites,
pertinent information/data available in the database will be reviewed to identify those sites with
the potential to create contaminated environmental media (soil, groundwater) within the project
limits of disturbance. VHB will prepare a brief technical memorandum to summarize the findings
of this desktop study, including a supporting figure and summary table to identify: the study
area; NHDES sites identified within the study area; and, the sites that, in VHB’s opinion, have the
potential to impact the project. The memorandum will also include recommendations for further
investigation and/or construction management planning, as appropriate. VHB’s opinions of
potential project impact are not certainties as we expect they will be based on observations

made by others from widely spaced exploration and testing.

Follow-up exploration and testing may be recommended based on the OneStop database
review. Given that the necessity and scope of potential testing is unknown at this time, the costs
for additional investigation (e.g., confirmatory pre-construction soil or groundwater sampling
within the project area), should it be recommended, are not included in this proposal. We
understand that any such required environmental sampling may become the responsibility of
the construction manager, although VHB can assist with or conduct those investigations upon

amendment of this scope.

Task 14. Soil & Groundwater Management Planning

Building on the findings from the Soil and Groundwater Desktop Study, and in consideration of
project requirements, VHB will prepare a Soil and Groundwater Management Plan (SGMP) for
use during construction. The purpose of the SGMP will be to provide guidance to the Contractor

The City of Nashua may reject any or all of the bids on any basis and without disclosure of a reason. The failure to make
such a disclosure shall not result in accrual of any right, claim or cause of action by any unsuccessful bidder against the
City of Nashua. The City of Nashua reserves the right to waive any irregularities when the public interest will be served
thereby. The City of Nashua also reserves the right to negotiate any change or amendment in any bid without soliciting
further bids if the action is necessary for the best interest of the City of Nashua.

All bids are binding for ninety (90) days following the deadline for bids, or until the effective date of any resulting

Insurance during the term of the contract. Liability limits are as follows:

*Coverage must include all owned, non-owned and hired vehicles.

> Workers’ Compensation Coverage according to Statute of the State of New Hampshire:

The City of Nashua must be named as an additional insured on all liability certificates.

All bidders and subcontractors at every tier under the bidder will fully comply with NH RSA Chapter 281-A,
“Workers’ Compensation”.

It is the responsibility of the Contractor to submit to the City of Nashua certificates of insurance for the Contractor and all
other subcontractors prior to the start of the project. It is the responsibility of the Contractor to provide the City of Nashua
with updated certificates of insurance for the Contractor and all subcontractors 10 days prior to the expiration of coverage.
The City of Nashua may, at any time, order the Contractor to stop work, suspend the contract or terminate the contract for
non-compliance. Ali subcontractors are subject to the same insurance requirements as the Contractor.

No bid will be considered unless accompanied by a bid security in the form of a Bid Bond, in an amount not less than five
percent (5%) of the Total Bid Price.

The successful Contractor will be required to post a 100% Performance Bond and a 100% Payment Bond in an amount
equal to the Contract Award.

Cost of bond premiums to be included in the Lump Sum Bid Proposal.

The City of Nashua is exempt of all taxes. All bids must be FOB Nashua, NH. All bidders must comply with all
applicable Equal Employment Opportunity laws and regulations.

Pursuant to NRO 5-78 (F), the Purchasing Manager shall not solicit a bid from a contractor who is in default on the
payment of taxes, licenses or other monies due the City of Nashua. Therefore, this bid request is void as to anyone who is
in default on said payments.
