Re: Change Order Request Review 025

NWWYTF Energy Recovery Upgrade Project

Attachments: Methuen Construction PCO-025 Fuel train re-build

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 pumps. Methuen has previously submitted for the related electrical scope of work.

Original Cost Cost Adjustment Direct Cost Impact Cost Adjustment

Detailed Review-Base Cost Validity

Methuen has made a claim for the work as required based on RFI responses, submittal reviews
aud 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 a
tequirement from CAT to accommodate fuel train components of mis-sized (not all one
corresponding size) into a single assembly, While the fuel tian components were listed as a ship
loose item, it is not reasonable that the contractor would understand that those pieces of
equipment would be mis-szied. We also note that CAT was requested to reduce their fuel train
pressure drop to accoiadate the operating profile of the blending skid, and this lead to revised fuel
train component selctions, which were not all available in a full menu of sizes, which elad to the
mis-matched sizes (i.e. it was not logistically feasible to get every component in 2 4")

Engineering Department

2022 CIPP Lining Program - Construction

To approve the award of the construction contract for the 2022 CIPP Lining Program to
Kenyon Pipeline Inspection, LLC of Queensbury, NY in the amount of $1,412,170.
Funding will be through: Department: 169 Wastewater; Fund: Wastewater; Activity:
Sewer Rehab.

The annual sewer program addresses aged and failing sewer pipes and structures. The
2022 CIPP (Cured-in-Place-Pipe) Lining program is expected to video inspect
approximately 75,000 feet of sewer pipe, line approximately 18,000 feet of sewer pipe
and rehabilitate approximately 60 sewer structures. Pipe lining is significantly less
expensive and less disruptive than full pipe replacement, and is instrumental in
rehabilitating the City’s sewer infrastructure.

Four bids were received on June 7th as follows:

Kenyon Pipeline Inspection, LLC of Queensbury, NY $1,412,170.00

National Water Main Cleaning Co. of Canton, MA $1,413,426.20
Inliner Solutions, LLC of Fairfield, ME $1,992,960.00
Insituform Technologies, LLC of Chesterfield, MO $1,885,785.00

The low bid was reviewed and found to be acceptable. Kenyon been working in Nashua
since 2019 and has performed well on previous sewer projects. Work is scheduled to start
in August following contract approval.

method) schedule showing how this item moved onto the critical path. Their schedule claim is
therefore evaluated at 0 days. Therefore we recommend 0 days be awarded.
