Re: Change Order Request Review 016
NWW'TF Energy Recovery Upgrade Project
Attachments: Methuen Construction PCO-016 JW Pump Install
Mr. Keating:

Waldron has compiled its review based on review of the Owner’s documentation (design
documents, OEM submittals, submittal reviews, RFI responses, and project notes} and the
Contractor’s documentation (RFI’s, Submittals, Reports, issued Change Orders). Specifically;
Waldron has reviewed the issue of additional work associated with the installation of the jacket
water booster pumps. Methuen has previously submitted for the related electrical scope of work.

Detailed Review-Base Cost Validity

Methuen has made a claim for the work as required based on RFI responses, submittal reviews
and Field conditions. The claim is based on their work and their subcontractor’s work resulting
from the above. Waldron has reviewed the design documents, OEM submittals, submittal
reviews, and RFI responses regarding this issue. Waldron has relied on vendor quotes, project
cost estimations, historical project data, RS Means, and its own proprietary cost data to review the
cost validity of the work scope.

The installation of TW booster pumps is required by Caterpillar, The pumps were not shown on
the project drawings and installing them is added cost to Methuen. Under separate cover,
Methuen has already submitted for the associated electrical costs (PCO-009). We recommend that
the Owner requests that Methuen submit all costs associated with a given change at the same time
in the future. This will prevent multiple rounds of review.

Mr. John Griffin

Chief Financial Officer

City of Nashua

229 Main Street

Nashua, New Hampshire 03061

Dear Mr. Griffin:

You have requested that we audit the basic financial statements of the governmental activities,
business-type activities, each major fund, and the aggregate remaining fund information of City
of Nashua, New Hampshire (the City) as of June 30, 2022 and 2023, and for the years then ended,
and the related notes to the financial statements. In addition, we will audit the City’s compliance
over major federal award programs for the years ended June 30, 2022 and 2023. We are pleased
to confirm our acceptance and our understanding of this audit engagement by means of this
letter.

The objectives of our audit of our financial statements are to obtain reasonable assurance about
whether the financial statements as a whole are free from material misstatement, whether due
to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance
is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an
audit conducted in accordance with auditing standards generally accepted in the United States of
America (GAAS) and, in accordance with Government Auditing Standards, will always detect a
material misstatement when it exists. Misstatements, including omissions, can arise from fraud
or error and are considered material if there is a substantial likelihood that, individually or in the
aggregate, they would influence the judgment made by a reasonable user based on the financial
statements.

The objectives of our compliance audit are to obtain sufficient appropriate audit evidence to form
an opinion and report at the level specified in the governmental audit requirement about
whether the entity complied in all material respects with the applicable compliance requirements
and identify audit and reporting requirements specified in the governmental audit requirement
that are supplementary to GAAS and Government Auditing Standards , if any, and perform
procedures to address those requirements.
