Re: Energy Recovery Upgrades — Construction Phase Services

C. Motion: To approve the contract with Waldron Engineering of Exeter, NH in an amount
not to exceed $76,762 for construction administration services for the Energy
Recovery Upgrade Project. Funding will be through: Department: 169-
Wastewater; Fund: Wastewater; Activity: Energy Recovery Upgrades.

Attachments: Waldron Engineering Contract

Discussion: The Nashua Wastewater Treatment Facility is undergoing an upgrade of its
energy recovery system.

Waldron Engineering is the design engineer and is very familiar with this project.
The project went out bid in August and 2 bids were received on September 6,
2018. The construction portion of this project is being awarded and construction
phase services from Waldron are needed.

Construction is estimated to last 8 months and Waldron’s services include
residential engineering and construction administration. Their cost proposal for
$76,762 is very reasonable when compared to the overall $1.78 million
construction costs. Typical construction phase service costs are around 8 to 10%
of construction costs, while this is only 5%.

RE: Energy Recovery Generator Upgrade
Construction Administration Service Proposal

Dear Mr. Keating,

Waldron Engineering and Construction, Inc. (Waldron) is pleased to submit the Construction

Upgrade Project. We have compiled this proposal based on the documents provided through your
discussion on the correct RFQ process.

Waldron looks forward to the opportunity to present our team and work with the facility. We are
confident we have a solid understanding of Construction Observational Site trips, General Contractor’s
RFI, Submittal reviews, Commissioning, and Operation Manual/Turnover packages and can deliver a
quality program that will insure a successful close-out project. We thank you for this opportunity to
present our offering and hope you can work with us to bring our design project to a successful
conclusion through a well-run construction process.

Sincerely,
Waldron Engineering & Construction, Inc.

i, Executive Summary

Waldron Engineering and Construction, Inc. (Waldron) has compiled a project team witha
depth of cogeneration construction, startup, commissioning, project closeout and waste
water treatment plant operations experience that will ensure success for the Construction
Administration aspects of the Waste Water Treatment Facility Energy Recovery Generator

months of the G.C.

e General Contractor Requests for Information (RFD

e General Contractor Submittal Reviews

e® Start-up & Commissioning of the ERU project

e@ Preparation of Turn-over package and an Operations Manual for the project

Our team uses proprietary, state-of-the art RFI/Submittal tracking databases which are
synchronized with our design specification requirements, making the integration of our
Design teams with our field team seamless. Our proposed lead for Commissioning has
recently completed similar work at Tuffs University and has a great familiarity with CAT
engines and their requirements. We conducted operator training, manage turn-over
packages and close-out documentation on similar projects

The Waldron team has the capability to assist the Waste Water Treatment Facility during
the critical construction and commissioning phases. We have a proven track record and
have delivered similar CHP projects within the established project budget, exceeding the
anticipated performance goal and more importantly, on time completion so that the
Facilities successfully achieved the energy efficiency and economic goal.

Waldron completed over 27 power generation projects from detailed design, construction,
startup and commissioning that enable us to oversee and guide the G.C. to successful
implement your project in the field.

We have the experience to make your project a success. Our CHP project post-design
services have been a large part of what has made our projects so successful through the
years. We are confident to make this project a success for the City of Nashua Waste Water
