| District Energy
System Study and Implementation
(Metropolitan Government of
Nashville and Davidson County, Tennessee)
As a result of GBB's
comprehensive solid waste management analysis for the
Metropolitan Government of Nashville and Davidson County
(Metro), Metro selected the alternative of replacing
its aging and inefficient waste-to-energy Nashville
Thermal Transfer Corporation facility ("Thermal")
with a new District Energy System in downtown Nashville.
GBB was retained by Metro to manage the procurement
process for selecting a contractor to design, build
and operate the new Energy system. GBB prepared the
Request for Proposals, assisted Metro in evaluating
the proposers, negotiated a successful contract with
the selected proposer, and managed the implementation
of the project.
GBB also was the lead
consultant in the feasibility study leading to the successful
financing of $66.7 million in bonds to finance, in part,
the construction of the new 43,450 square foot, two-story
building housing the highly efficient steam and chilled
water generating facility.
The new facility, which
began operating in December 2003, was implemented with
several important objectives in mind:
- To utilize state-of-the-art equipment
and its high reliability;
- To keep costs as reasonable as
possible and very predictable to DES customers;
- To be an attractive facility, both
visually and to the environment;
- To be a positive
catalyst for economic stability and growth in downtown
Nashville.
On April 19, 2004, the
Nashville Thermal Transfer Corporation formally turned
over the 30-year-old Thermal Waste-to-Energy plant to
Anderson Excavating Company of Omaha, Nebraska, for
complete demolition.

The overall demolition
process is being managed by GBB. One of the unique aspects
of the “dismantling of Thermal” was an auction
process of Thermal’s fixed and used mobile equipment
and parts. Over 150 auction transactions for the resale
and reuse of used equipment brought $983,362 to the
Metro Nashville government, owner of the Thermal assets,
reducing the overall cost to close Thermal.
The five-month
project included the implosion of the large 200 foot
concrete stack on July 26, 2004. Approximately 98.5%
of the materials within the demolished structures were
recycled as crushed concrete aggregate, crushed asphalt
and metals.
GBB served
as Metro's Project Administrator, from beginning
through February 2007, overseeing all phases of the
project, including adding new customers and the transition
and closing of Thermal.

Testimonial:
"I would
like to take this opportunity to let you [Harvey Gershman
- Metro Nashville DES Project Administrator and GBB
President] and know how much I appreciated how you and
your organization handled the transition from the old
Thermal plant to the new District Energy System.
There were several aspects of
the process that were done particularly well. First
and foremost the communication from you to us, the customer,
was consistently timely and thorough.
I absolutely appreciated the customer
meetings that you hosted that gave us a voice in the
decisions concerning service interruption scheduling.
Once a decision had been made to schedule the interruption
of service, you always stayed inside your time estimates.
That was most impressive and pleasantly surprising.
I would also like to commend Mr.Chuck
Tucker. He and I spoke often throughout the process.
He came to the Ryman and met with me and my maintenance
staff and showed us the step-by-step process of shutting
ourselves down prior to the service interruption and
the reverse process for the restoration of service for
both the steam and the chill water. It was very reassuring
to know that Chuck was out there on the job.
In the aftermath of the transition,
we have had nothing but flawless service. You can count
Ryman Auditorium as a "satisfied customer""
