Ann: Becoming a substantial holder from CBA, page-8

Decmil's recent financial performance indicates they are abysmal in project execution. Four losses in the last five years is all the proof you need.

The only way Decmil could take advantage of an upcoming government spend in infrastructure is if they significantly improve their project delivery. You cannot simply click your fingers to make this happen. Poor delivery is an organisational cancer which takes years to remedy. I doubt it will ever happen at Decmil unless drastic organisational changes are made. The top would be a good place to start.
