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 relocation of the fuel
blending skid.

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 relocation of the fuel blending skid was to maintain access to the digester equipment. MC did
need to extend piping and provide on-wall pipe supports. MC was able to remove pipe stanchion
supports that would have been required in the original design. MC was also able to remove
foundations for pipe stanchions.
Overall Waldron concurs with MC’s representation of their costs, but recommends a higher value
be assigned to the deduct.
