Gamuda workforce is only around 3,500. It's nowhere up to 20K. The 20K will likely include contractors and sub-contractors workers who are not under Gamuda's payroll.

The project is not cancelled. They are opening the underground work for open tender again. The above ground work is proceeding as schedule and Gamuda is still under contract to do the job. When the new company wins the open tender, they will still need to engage contractors and sub-contractors.

In 2015, the Budget under BN for the whole project was around 20+ billion. This means that the project was awarded to Gamuda back in 2015 based on the estimated cost of 20+ billion. Today the cost have shoot up to 50+ billion. It's normal for projects to cost more than budget but more than 100% increase is just ridiculous. Anyone in business will do the same thing as PH government.
