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 dacumentation (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,

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 submitted PCO is based on additions to the work encountered in the field around Engineering
change notice (ECN) regarding transfer of the HMI programming scope from NWWTF as a self-
perform, to add to the contractors’ scope of work. As this is added work, the addition is valid, and
needs only the assessment of the FMV.
