Firms interested in bidding for contracts on phase 1 of the project were due to submit statements of intent to the government by mid June 2013.

The Department of Transport has planned phase 1 for construction in three contracts:

  1. civil works for the above-ground structures (design and build contracts).
  2. underground construction work (design and build contracts)
  3. the rail system, the rolling stock and the operation and maintenance for the line; (design, build, operate and maintain contracts.)

Contracts are due to be awarded in 2015. Under the original plan, the first phase was due to be complete by 2015, but is now scheduled to be operational no sooner than 2016–2017
