Boiler Repairs — Change Order #2

To approve Change Order #2 in the amount of $16,939.29 to the contract with
Armand E. Lemire Company Co., Inc. of Hooksett, NH for the installation of new
boilers at the Wastewater Treatment Facility. | Funding will be through
Department: 169 Wastewater; Fund: Wastewater; Account Classification: 81
Capital Improvements.

The original contract in the amount of $61,080 included labor only for the
installation of the new boilers, demo the remaining boiler and install the
condensate pump. Purchase Order # 123277 was issued. Change Order #1 in the
amount of $8,755.85 was processed when it was determined to be more
advantageous to have Lemire purchase the materials (miscellaneous pipe fittings
and check valves) directly.

Change Order #2 in the amount of $16,939.29 became necessary when the
contractor went to install the three new condensate pumps, they discovered that
the piping to and from the existing condensate pumps were so riddled with holes,
that additional labor was necessary to replace the piping to and from the
condensate pumps. Additionally, the burner controls had to be removed from the
burners and relocated to allow the units to fit within the boiler room itself. This
relocation required that the controls be rewired. This work was authorized at the
time to not stall the project.

Finally, there were two gas pressure regulators bought with the original boilers.
One regulator is rated for 1 psi and the other regulator is rated for 0.5 psi. The gas
pressure at the main at the facility is 2.0 psi. The contractor has quoted $2,520 to
purchase and install the correct size pressure regulators.

Upon approval of Change Order #2 the total contract value will be $86,775.14.

1. Relocation of 2 burners and rewire of controls:

Time & Material for the relocation of two (2) burners. There was not enough room to access these
control panels and it was mutually agreed upon that they needed relocating. Procontrols did all

of the rewiring necessary.

Dear Honorable Mayor and Board of Aldermen:

We have audited the financial statements of the City of Nashua, New Hampshire as

of and for the year ended June 30, 2015 and have issued our report thereon dated
December 30, 2015. Professional standards require that we advise you of the following
matters relating to our audit.

Our Responsibility in Relation to the Financial Statement Audit

As communicated in our engagement letter, our responsibility, as described by profes-
sional standards, is to form and express an opinion about whether the financial state-
ments that have been prepared by management with your oversight are presented fairly,
in all material respects, in conformity with accounting principles generally accepted in the
United States of America. Our audit of the financial statements does not relieve you or
management of your respective responsibilities.

Our responsibility, as prescribed by professional standards, is to plan and perform our
audit to obtain reasonable, rather than absolute, assurance about whether the financial
statements are free of material misstatement. An audit of financial statements includes
consideration of internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the entity's internal control over financial
reporting. Accordingly, as part of our audit, we considered the internal control of the City
solely for the purpose of determining our audit procedures and not to provide any assur-
ance concerning such internal control.

We are also responsible for communicating significant matters related to the audit that
are, in our professional judgment, relevant to your responsibilities in overseeing the
financial reporting process. However, we are not required to design procedures for the
purpose of identifying other matters to communicate to you.

Planned Scope and Timing of the Audit

We conducted our audit consistent with the planned scope and timing we previously
communicated to you.

Compliance with All Ethics Requirements Regarding Independence

The engagement team and others in our Firm have complied with all relevant ethical
requirements regarding independence. Safeguards that have been applied to eliminate
threats to independence or reduce them to an acceptable level include annual certifica-
tion by all Firm staff of independence.

Qualitative Aspects of the Entity’s Significant Accounting Practices
Significant Accounting Policies

Management has the responsibility to select and use appropriate accounting policies.
A summary of the significant accounting policies adopted by the City is included in the
notes to the financial statements. There have been no new accounting policies and no
changes in significant accounting policies or their application during the year ended
June 30, 2015. No matters have come to our attention that would require us, under
professional standards, to inform you about (1) the methods used to account for sig-
nificant unusual transactions and (2) the effect of significant accounting policies in
controversial or emerging areas for which there is a lack of authoritative guidance or
consensus.

Significant Accounting Estimates

Accounting estimates are an integral part of the financial statements prepared by man-
agement and are based on management's current judgments. Those judgments are
normally based on knowledge and experience about past and current events and
assumptions about future events. Certain accounting estimates are particularly sensitive
because of their significance to the financial statements and because of the possibility
that future events affecting them may differ markedly from management's current
judgments.

The most sensitive accounting estimates affecting the financial statements are:

e Estimated lives and depreciation methods for depreciable assets.

e Collectability of receivables.

e Net OPEB obligation.

e Net pension liability.
Management's estimates of the above are based on various criteria. We evaluated the
key factors and assumptions used to develop these estimates and determined that it is

reasonable in relation to the basic financial statements taken as a whole and in relation
to the applicable opinion units.
