Contract Award Of West Coast Highway is a Sham

It is disconcerting to learn that the West Coast Highway mooted in 1996 but put on hold because of the Asian financial crisis will be given to the original contractors awarded 11 years ago.
A project awarded 11 years ago certainly has no justification to be given to the same contractor unless the project was awarded in an open tender in 2007.
Cost of labour and price of material fluctuate over time and can bear no relationship after a period of 11 years. So on what basis was the Highway contract awarded to the same contractor?
How did the estimated cost of $3.12 billion been awarded to the contractor if there was no competitive bid for the project?
Surely a project of such magnitude would demand greater transparency and accountability.
The concessionaires for the project include Kumpulan Europlus Bhd and the contractor is Konsortium LPB Sdn Bhd.
As taxpayers whose money are being used for this project I think we are entitled to know how and on what basis this contract was awarded and who are the principal beneficiaries of this Highway Project.
