Fixed Link between Labrador and Newfoundland Pre-feasibility Study Final Report
7 ECONOMIC AND BUSINESS CASE ANALYSIS This section sets out the economic and business case analysis. Three cases are described: The Base Case - bored (TBM) tunnel with a railway shuttle; Upgraded Ferry Link from St Barbe to Blanc Sablon; and, The Base Case augmented by High Voltage Direct Current (HVDC) transmission income.
The tunnel option under consideration uses two TBM machines and a seven day work week; thus, the period for planning design and construction of the facility is 11 years and the operating period examined is 30 years, for a total economic life cycle of 41 years. Sensitivity analyses were also carried out to assess the possible effects of significant changes to the assumptions underlying these forecasts. There are three major parts to this Section, as follows:
