Re: Change Order Request Review 028

NWWTE Energy Recovery Upgrade Project

Attachments: Methuen Construction PCO-028 Electrical items (list of six)

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 installation of the jacket
water booster purops. Methuen has previously submitted for the related electrical scope of work.

Summary Review

Adjustment claim Impact Assessment Recommended

Original Cost Cost Adjustment Direct Cost Impact Cost Adjustment

None $17,168 $736 3736

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 respouses regarding this issue. Waldron has relied on vendor quotes, project
cost estimations, histozical 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 for various electrical items which MC
believes are additional to the project, The various items are summarized in the next sheet as to
their validity and any specific reasons. Generally, items which are unforesecable-unknow existing
conditions or legitimate additional work requested by others are recommended, Those that are
foreseeable work due to conditions that could have or should have been assessed during bid
walkthroughs, or are the result of trade-to-itade coordination (which is the responsibility of the
G.C.} are not recommended.
