Re: How did this happen?
Telstra has been outsourcing pit and pipe work for a very long time to companies like Transfield and Silcar. Each in turn bid low to get the contract and each then struggled to find subcontractors who would work for the rates they offered at the speed they required and at a quality that was good enough to avoid incurring penalties from Telstra. I understand that Telstra is now bringing some of it back in house as NBN has changed contractors to competitors.
