> DREDGING & THE ECONOMY
“The health of the U.S. economy depends, in part, upon the vitality and expansion of international trade.
International trade depends upon the Nation’s navigation infrastructure, which serves as a conduit for
transportation,
trade,
and
tourism
and
connects
us
to
the
global
community.
Marine transportation is one of the most efficient, effective, safe and environmentally sound ways to transport
people and goods. It is a keystone of the U.S. economy. Ninety-five percent of our international trade moves
through the Nation’s ports.”

> ACQUISITION OF TERRA CONTRACTING, LLC
>
On December 31, 2012, Great Lakes acquired the assets of Terra
Contracting, LLC (Terra).
>
Terra is a respected provider of a wide variety of essential services for
environmental, maintenance and infrastructure-related applications.
>
Headquartered in Kalamazoo, MI, Terra employs approximately 200
engineering, operations and administrative staff and serves customers in
more than thirty states in the environmental, infrastructure, energy,
industrial, transportation, waste water and construction sectors.
>
Terra will broaden our demolition segment with additional services and
expertise as well as expand our footprint in the Midwest. Terra reinforces
our efforts to develop relationships with larger industrial and governmental
clients. Additionally, our rivers & lakes operations can leverage Terra's
environmental remediation focus to accelerate its participation in the
environmental dredging market.
>
The purchase price was approximately $26 million.
>
The Company has announced that it is assessing strategic alternatives with
respect to its historical demolition business –
which would not include Terra
Contracting.

The scows will be used primarily on capital deepening and coastal restoration
work on the East and Gulf coasts.

GLDD has become very successful loading scows with cutter suction dredges.
This has allowed us to match the dredging ability of the cutter suction dredges
on projects, giving us an effective transportation system and a cost advantage
over our competitors.
>
Construction of the dredge and scows created approximately 250 new U.S.
shipyard and engineering jobs over the construction period.

Government
Regulations
Increased
Environmental
Focus
Decades of minimal capital expenditure in the industrial, oil & gas, utility, and public sectors
Average U.S. oil refinery was sited and constructed over fifty years ago
Average age of the U.S. coal fleet is 43 years, with more than half the plants built before 1967
American Society of Civil Engineers estimates investment needed by 2020 in U.S. infrastructure is
$3.6 Trillion
Discovery of shale gas and fracking technology have resulted in increased infrastructure spend and
expected to lead to need for site cleanups and waste disposal, as well as site remediation and
redevelopment
Expansion and improvement of midstream assets and refining capacity is expected: natural gas,
natural gas liquids (NGL), and oil transmission infrastructure spend is estimated to be more than
$250 billion over the next 25 years
New / specialized waste streams and treatment driving need for increased environmental regulation
Both federal and state governments have increased oversight of environmental practices, tightened
mandates, and increased legislation
EPA mandates to lower greenhouse gas emissions and improve efficiency of big power plants are
expected to increase
Sustainability
is
increasingly
viewed
as
a
source
of
revenue
and
business
growth
Consumers demanding greener technologies, products and services
Random and unfortunate events (e.g. BP oil spill) require environmental remediation and clean-up,
Hurricane Sandy clean-up is continuing
Superfund sites in the Northeast due to reduced land inventory are now obtaining funding for
