Mr. Keating:

Waldron has compiled its review based on review of the Owner’s documentation (design
documents, OEM submitials, 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 subcontractors 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 field
installation of the SCAC systems for Engines 1&2. Installation of the SCAC flex hoses was a
foreseeable project work as it was listed as a ship loose item. However the work was more
complicated than the simple ship loose listing. Waldron’s opinion is to offer the contract % of the
assed market value of the additional installation 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

The submitted PCO is based on additions to the work encountered in the field around a
requirement from Eversource to include a breaker status wired point. The conduit for this already
existed, but new wire had to be pulled in to accommodate this work. This is an extra to the overall
scope of work.
