 Due to the audit process- the GNWT has taken action
  concurrently to the review and has already completed
  some recommendations, with others well underway.
Findings and Recommendations (2)
 Nothing found in Phase 1 that impacts the safety of the work to
    date or that would affect construction of Phase 2
   Deficiencies were found in Phase 1 document control which,
    given further time and research, may be remedied
   Recommendation that Phase 1 works be accepted upon
    completion of the recommendations
   GWNT has accepted the Levelton Report and has the resources
    and time available to address all the recommendations.
   Our main priority remains to complete the project safely and to
