Energy Recovery Upgrade — Methuen Construction Change Order #6

To approve Change Order #6 to the Energy Recovery Upgrade contract with Methuen
Construction Company of Plaistow, NH in an amount not to exceed $5,619.29 for
structural support modifications to the energy recovery room. Funding will be through:
Department: 169- Wastewater; Fund: Wastewater; Activity: Energy Recovery Upgrade
Project.

Change Order #6

The energy recovery upgrade project involves upgrading all the major components in the
energy recovery room with new generators, piping, heat exchangers, pumps, controls and
associated electrical components. The contract with Methuen Construction was originally
in the amount of $1,787,378. Change orders 1 thru 5 were for various modifications to
the original layout largely due to unforeseen building conflicts and/or additional items
(pumps, electrical sizing) required by the equipment manufacturer (Milton CAT) that
came after the project was bid and approved. The total of change orders 1-5 is
$118,590.98 with a new contract value of $1,905,968.98.

Change order 6 consists of 2 items. The first item (PCO015) is for supports for 2 ground
level heat exchangers. Normally a vendor supplied heat exchanger comes with supports
attached to it which can be fastened into a concrete pad. That was not the case and the
contractor has to fabricate and install supports in an amount of $3,372.53. The second
item (PCO016) 1s for supports to mount the jacket water pumps to the ceiling. The
contractor was informed by supplier Milton CAT after the work started that it would be
necessary to install the jacket water pumps. This was not part of the Contractor’s scope
and costs for this work is in an amount of $2,246.76.

Re: Change Order Request Review 015

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 providing support stands for

HW-HX1 & 2.

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.

Specifically, Methuen constructed support stands for HW-HX1 & FX2 which was not part of
their original work scope. These heat exchangers were provided by the reciprocating engine
vendor. The original design expected these heat exchangers to be provided with a built-in base
with anchor holes. However, this was not specified explicitly. The heat exchangers were
provided without this accessory and this required field coordination to resolve. Due to the lead
time associated with ordering a catalog component, Waldron recommended Methuen field

fabricate the support stands. Refer to RFI-046.
