Soon afterwards, the University of
Alberta invited him to return to pursue a Master’s degree.
Jason credits good fortune for teaming him with academic supervisor, Dr.
Sam Ariaratnam, who was researching a relatively new area: trenchless
technologies. After completing his Master’s degree, Jason entered the
Ph.D. program, researching directional drilling, and working part-time
for a contractor as a project manager on water and sewer pipe-bursting
projects.
Just newly married and finishing his Ph.D., Jason started looking for
full-time work that would utilize his growing knowledge in trenchless
technologies. He contacted Chris Skowronski (now Vice President,
Infrastructure), who he knew from their mutual involvement with the
North American Society for Trenchless Technology (NASTT). Having met
Chris at several functions, Jason had heard some good things about
In 2012, Jason and his family decided to move back to Alberta. With
a desire to continue pursuing academia, Jason explored a teaching
position in a civil engineering degree program. Jason contacted Chris for
a reference, which in turn led to a call from Herb Kuehne and an offer he
couldn’t resist: to return to Associated Engineering in a role as National
Practice Leader of Trenchless Technologies.
Since returning to the company, Jason has provided technical support
to develop and implement projects with trenchless technologies.
Recent successes have included major projects in Winnipeg, Manitoba
and St. Albert, Alberta. Jason shares, “Our clients have become much
more aware and educated about trenchless technologies. They now
actively request trenchless solutions, so my job is less about selling the
technology and more about implementing designs that incorporate
trenchless methods.”
Jason enjoys his role providing technical guidance to staff. He tells us, “I
think this is the role I was destined to do.” He believes in treating others
as equals as it provides an environment for them to succeed and take
ownership. Jason says, “Sometimes, I think I learn more from the younger
staff than they learn from me.”
Outside of the office, Jason enjoys traveling and camping with his family.

Effective data management system helps to preserve
the cultural history of the Tłı̨chǫ people in the Northwest
Territories
The first step in the Regenerative Design process is to draft a Purpose
Statement. This statement has three components:
• The ‘function’ component: “What services would the data management
system do to protect and preserve the Tłıchǫ culture?”
• The ‘being’ component: “How will the data management
system support the Tłıchǫ people?”
• The ‘will’ component: “Why is a “Cultural Commons” important?”
The result of this work establishes a clear understanding, not only about
what the work is, but also the motivation and final impact that doing
the work will have for the Tłıchǫ people. The draft purpose statement
Tłıchǫ Government members participate in a Regenerative Design
Workshop
One of the most exciting challenges facing the new Tłıchǫ Government
(formed in 2005) is the preservation and growth of Tłıchǫ (also known
as Dogrib) culture and traditions. The Department of Culture and Lands
Protection is currently accumulating pictures, audio recordings, videos,
and documents from Tłıchǫ members. To date, over 30,000 items have
been collected and digitized. The items provide insights into Tlichǫ
history, cultural practices, and traditional knowledge.
Recognizing the importance and popularity of the data, the Tłıchǫ
Government engaged the environmental science division of Associated
Engineering to recommend an approach to develop and implement a
meaningful and effective data management system.
To begin, our project team led a two-day workshop in Yellowknife, NT,
to clarify the purpose and outcomes of the data management system;
present a range of feasible data management solutions/options and
their strengths and weaknesses; develop a clear path forward that would
produce a meaningful data management system; and provide a clear
framework for the data management system to meet government and
community requirements for at the next 10-20 years.
Senior Facilitator, Kathy Porter, designed a strategic planning process
to engage Tłıchǫ staff in exploring the challenges and opportunities of
storing the data in a secure yet accessible location. Rebekka Lindskoog,
an Information Management Specialist, prepared and presented the
background and technical information for the workshop.
A Regenerative Design framework, designed to accommodate individual
levels of expertise and knowledge, offered a new way of thinking
about the project’s purpose. A consensus-based decision process
was particularly appropriate for this approach as the understanding
that comes from sharing technical information along with cultural and
historical values is critical.
Kathy tells us, “As exploration progresses, understanding emerges
and interests and perspectives begin to converge.” The approach
allowed participants to integrate local and technical knowledge through
active dialogue, leading to a shared vision and purpose for a “cultural
stated, “To capture, share and categorize the Tłıchǫ way of life, in a way
that is accessible to Tłıchǫ people and government to maintain, preserve,
protect, and enhance public and private histories so that people are
encouraged to enjoy, share, teach, and learn to help increase pride and
dignity among Tłıchǫ people.”
The Regenerative Design Process helped
to clarify the purposes and outcomes and
provide future direction
The workshop objectives were framed using the Regenerative Design
Tetrad, where the dynamic tension between the motivation or the
intended goal and the means, including the resources required to take
the project in a certain direction, are considered. Kathy says, “By framing
the interests in this way, participants can begin to see how the Purpose
Statement and the seemingly divergent perspectives contribute to the
thinking that will be required to complete the Cultural Commons project.”
During the workshop, participants discussed the vast amount of
information that could be available for input into a data management
system. Workshop participants also considered their fears and hopes
(people, funds, and time) when considering how to address data
management. Rebekka says, “This information then formed part of the
consideration on the assumptions, risks, and constraints that could
support or hinder fulfillment of the Purpose Statement.”
With the draft strategic plan, the Tłıchǫ Government now has the
basis for developing and implementing a relevant, customized data
management solution to help store and access their sensitive and rich
history.

Highway 17 (South Fraser Perimeter Road) and Golden Ears Way in
Surrey, BC, and will help to reduce travel times.
The project includes the Connector, improvements to seven
intersections, a multi-use path connection to the Surrey Bend Regional
Park, the Leoran Brook Bridge, traffic signals, roadway and intersection
lighting, drainage design, stormwater quality treatment design, a
1.8 metre diameter fish and wildlife passable culvert crossing, utility
relocations, traffic assessments, environmental assessment, and
restoration planting design.
As prime consultant to the BC Ministry of Transportation and
Infrastructure, our project team addressed several key challenges.
One of the challenges is the site’s soft ground conditions which
required a combination of ground improvement measures, including
sub-excavation, preloading/surcharging (up to eight months), and
lightweight fill to mitigate settlement. Our Project Manager, Ron Gratz,
says, “We developed an earthwork strategy that maximizes the re-use of
existing preload materials and concrete blocks for subsequent preload/
surcharge stages.
Another key design challenge was the need to minimize property impacts
to accommodate the roadway footprint within a limited right-of-way along
a section of Daly Road and to meet the water quality objectives. The team
developed a solution using a combination of bioswales, filter strips, and
mechanical treatment devices to provide water quality treatment for
runoff from all paved surfaces, to meet the water quality objectives prior
The project is located within an environmentally sensitive area. As part of
the design, we carried out an environmental assessment of the impacts
to sensitive watercourses and adjacent riparian areas, wildlife habitat,
and sensitive vegetation from the roadworks. A riparian restoration and
re-vegetation planting design was developed to offset the impacts and
to meet the requirements of the Department of Fisheries and Oceans
Authorization and to ensure compatibility with the existing sensitive
habitat.
The 68 metre long, three-span Leoran Brook Bridge, which crosses the
environmentally sensitive Leoran Brook ravine, is designed to minimize
in-stream work and impacts to riparian vegetation. Senior Transportation
Engineer, Priscilla Tsang, tells us, “Our design of the bridge and road also
takes into account the potential impacts of extreme storm events. We
evaluated backwater effects and potential flooding to establish the bridge
and road elevations.“
Temporary traffic management was a major design consideration. Ron
tells us, “We developed a two-stage construction staging plan to maintain
traffic and access during construction to local commercial and industrial

A comprehensive 10-year strategy helps Wood Buffalo meet
immediate and long-term needs and develop secure drinking
water supply in Fort McMurray
The team met the challenge, developing a phased ten year program that
provided immediate benefits and improvements to water quality at the
end of each phase. The first phase, implemented in 2005, optimized the
water treatment plant processes and implemented new processes within
the facility’s footprint, almost doubling capacity of the plant and meeting
more stringent treatment requirements.

Filtered Water Transfer Station
The Regional Municipality of Wood Buffalo was faced with the enormous
challenge of managing the needs of population growth of 90% over 10
years. Oil exploration, oilfield construction, and increased oil production
in the Fort McMurray region triggered a steep migrant population growth,
as well as high transient population. Providing municipal services to
address the volatile growth required dynamic planning.
The population boom resulted in a number of changes to the design
population as the design of the water treatment plant progressed. The
team addressed the changes in design population by developing a design
centered on using a peaking plant concept to maximize flexibility and
address a wide range of potential water demand scenarios. The design
used the existing plant as the production facility for base loads, with
escalating demands handled by the new, higher rate water production
