specifications and a health and safety plan approved by the Crown.
The specs serve as a foundation for maintaining a safety regimen.
For example, workers within a certain distance of water must wear
flotation devices. In addition, workers also participate in tool box
talks to review safety procedures.
Collaboration is Key

be like before we even start blasting," Oram says.
The Department of National Defence also works closely with
marine biologists and other consultants to ensure that it adheres to
provincial environmental regulations regarding the treatment and
disposal of dredging material. Special attention is paid to contaminants in the excavated material.
The Halifax Jetty project, though headed by the Department of
National Defence, is a collaborative effort between several organizations. Key stakeholders in the Halifax Jetty project include the
Department of Fisheries and Oceans, Halifax Port Authority, Halifax
Harbour Bridges and Defence Construction Canada.
Oram has been with the Department of National Defence for
almost 10 years and has learned lessons from the jetty project,
including the benefits of collaboration. "Engaging all stakeholders
is always the best way to proceed," he says. "We're working together,
rather than creating an adversarial environment. We want to do our
job and deliver something great for the military."
The Department of National Defence maintains a vast infrastructure across Canada, which is being updated, in part, through projects
funded by the Federal Infrastructure Investments Program. These
projects include several jobs at Canadian Forces Ammunition Depot
Bedford located within the Halifax Regional Municipality of Nova
Scotia, as well as extensive work at CFB Halifax.

it's going to be like before we start blasting.'
In addition, the Department of Fisheries and Oceans offers its
expertise on the project and chimes in about the risk of disrupting
aquatic life and damaging the underwater environment. "We work
together in a collaborative way to understand the environmental
impact and then come up with a compensation plan," Oram says.
"We're firmly committed to do right by the aquatic environment."
One of these compensation plans involves creating new underwater habitats. Because any type of construction involving underwater
blasting will cause some environmental damage, the Department of
National Defence has offered to build artificial reefs. In this particular case, 75 reef balls made from poured concrete using casts, were
installed in 15 groups of five each on the ocean floor to form the
supporting structure for a new reef habitat.
Safety is a top concern for the Department of National Defence, and
the jetty project team is committed to creating a safe work environment. Contractors for the Halifax Jetty project - Dexter Construction
