PROJECT INTRODUCTION

  • The Canada North Fibre Loop (CNFL) is a Northwestel (NWTel) driven project

to complete a fibre loop between 26 terrestrial Northern communities in the Yukon and the Northwest Territories.

  • This loop will be accomplished by running a 775 km length of fibre cable

along the Dempster Highway from Dawson City, YT to Inuvik, NT and joining up with the Mackenzie Valley fibre line currently under construction.

  • Presentation includes 2 main portions:
  • Description of fibre redundancy
  • Description of scope of work for geotechnical and geophysical studies
  • Phase 1 of this project is to finalise the design and cost.
  • Phase 1 includes desk top assessments, GIS work and some field work.
  • As recommended by the Gwich'in Land and Water Board, we are reaching out

to all stakeholders and First Nations to discuss the project and the requirement for this small drilling program in particular.

FIBRE REDUNDANCY

  • Current situation results in service disruptions for

Northern communities

  • Solution requires significant investment in fibre

infrastructure Northwestel seeking to implement self-healing fibre rings to protect services for communities in the Yukon and Northwest Territories

FIBRE WITH NO DIVERSITY (CURRENT STATE)

  • If fibre is damaged due to events such as a forest fire or

a contractor who cut the line while doing work along the road – then service between communities 1 and 2, and then communities 2, 3 and 4, is disrupted.

  • Depending on location of damaged cable, it can take

from 6 to 12 hours to mobilize resources to repair the cable, travel to the site, complete repairs & restore service.

  • As businesses increasingly rely on the Internet to
  • perate – whether for point-of-sale equipment, inventory

management, purchasing, airline passenger check-in or a host of other applications – any service outage can result in forced shut-downs and/or closures until service is restored.

Fibre damage can have significant impact on the economy & community

SELF HEALING FIBRE LOOP (FUTURE STATE)

  • A fibre loop (or ring) can be compared to an oval

racetrack: there are 2 ways around the track and if you start in one direction and encounter an

  • bstruction, you can simply turn and go the other way

around the track to get to the other locations.

  • With a ring, if the control equipment senses a

disruption in the data travelling in one direction, it simply re-routes traffic in the other direction so that communities remain fully connected.

Fibre rings are automatically self healing, maximizing network reliability, ensuring no loss of service for customers

CANADA NORTH FIBRE LOOP

  • Canada North Fibre Loop would connect fibre in the Yukon with the MVFL in the Northwest Territories, creating full

redundancy in the two Territories

  • Requires placing approximately 775km of fibre from Dawson City (YK) to Inuvik (NWT)
  • Benefits of this project – once complete, this self-healing fibre loop will provide robust protection against fibre cuts in:
  • Yukon, Northern BC and along the Mackenzie Valley in the NWT (26 communities)
  • Cellular and Internet in the satellite served communities in the North (36 communities)
  • In preparation for this link, Northwestel will complete the extension of the existing fibre from Stewart Crossing to Dawson

City in 2016

CANADA NORTH FIBRE LOOP STATUS

  • Yukon Government has endorsed the Canada North Fibre Loop as best solution for redundancy
  • Northwest Territories Government is supportive of this project
  • Nunavut Government supportive
  • High level cost estimates range significantly today, and phase 1 is to provide a more accurate estimate and

provide the project timing required to construct the fibre route, this information is needed to facilitate the approvals and funding needed to undertake the project

  • Proposed geo-technical work is important to clarify costs of boring under two major rivers in the NWT

PHASE 1 - STATUS

  • Initial planning stage:
  • Preliminary river crossing investigations
  • Route review
  • Construction methodology review
  • Stakeholder engagement
  • Desktop assessment of cultural, environmental and wildlife sensitivities
  • Geotechnical and geophysical investigations:
  • Current plan is to complete geotechnical and geophysical investigations at the Mackenzie

and Peel River crossings

  • Purpose is to understand subsurface details at existing ferry/ice bridge crossings in order to

determine cost and feasibility of crossing with a large horizontal directional drill (HDD)

  • Type A Land Use Permit required for investigations
  • NWTel and Ledcor Technical Services (LTS) will commence engagement with intent to

apply for the Type A Land Use Permit under the Gwich’in Land and Water Board (GLWB)

GEOTECHNICAL

Tools available include:

  • Standard Penetration Test (SPT) Hammer
  • Provides information about soils
  • Odex Percussion Down-the-Hole Hammer Drill
  • High penetration especially in rock
  • Good for soil sampling
  • Advantageous in unconsolidated formations
  • Mud Rotary Drill
  • drill often used when sediments may be

saturated with groundwater

GEOPHYSICAL

  • ERT (Electrical Resistivity Tomography)
  • Technique for imaging sub-surface geotechnical stratigraphy
  • Acquires a series of resistivity measurements from an array of very low

current electrodes contained in a wire that is placed along the bottom of the river.

  • The variation in the resistivity is what is used to delineate the subsurface

stratigraphy.

  • Low current poses no risk to fish or fish habitat.
  • Peel River – ERT approx 500 m in length
  • MacKenzie River – ERT approx 1.2 km in length
  • ERT Methodology
  • The ERT line will be positioned on the bottom of the river channel during

testing and up either bank of the river.

  • The line will be removed once testing is completed.
  • Navigable Waters not required for this program.

GEOPHYSICAL PROGRAM

  • Bathymetric Survey
  • Purpose to map profile of river bottom
  • Conducted using a ground penetrating radar (GPR)

system with controller, module and 100 MHz antenna

  • GPR sends a tiny pulse of energy and records strength

and time required for return of any reflected signal

  • Uses pulses to image the sub-surface
  • Non-intrusive method that poses no hazards to fish and

fish habitat

  • Geophysical program will be completed using an

aluminum boat/zodiac traversing along the proposed alignment.
