Presentation Agenda Background Aim of the Report Scope Findings Recommendations Actions Planned Conclusion Questions 3

Audit Background Phase 1 all works completed prior to 31 March 2010 under the DCBC Phase 2 all works under the GNWT Technical issues (design), fabrication, construction Quality control (QC) and quality assurance (QA) Due diligence dictated the GNWT review and understand what had taken place in Phase 1 Levelton Consultants assigned the role and commenced April/May 2010 and completed 30 Nov 2010 Audit employed interviews/documentation review/inspections to complete the audit. 4

Aim/Scope of the Audit Aim : To assure the GNWT that the “in place” works were constructed to standard and that all phase 2 works would be based on quality works. Scope: Confirm continuity of design responsibility; Confirm all issues raised in Ph 1 addressed; Confirm fabrication and construction QC/QA followed and certified Confirm general compliance with the contract and specs Identify issues required to close off the Phase 1 works 5

Findings and Recommendations (1) Findings divided into 6 main categories Section 6 of the Report details the formal recommendations. Some further notes in the main body of the report which are germane to the Project. GNWT has grouped the recommendations where they make sense and where one has a direct impact on the other. Due to the audit process- the GNWT has taken action concurrently to the review and has already completed some recommendations, with others well underway. 6

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 a high standard. 7
