But "30/10" is the act to get funding to build current projects such as the Downtown Regional Connector, the Subway towards the Sea, the Crenshaw, Green, Foothill Gold, Eastside Gold and Expo Light Rail Lines that would be spread in building over 30 years and to compact them into just 10.
In reality, all these projects are staggered in delivery. And Expo and Foothill Gold are under construction by different construction authorities. Metro is currently building the Orange Line extension, with the next project in queue being the Crenshaw Line. Crenshaw is very much line the Eastside Gold Line, which Metro built on-time, safely and on-budget.
The big, complex Connector and Subway won't break ground for about 4 years. The same folks that did the Eastside Gold Line can handle these two projects. The other projects such as the Green Line to LAX and to the Southbay will start after that.
As far as contracting and technical experience, there are plenty of teams out there that have built projects in LA and around the country and they have the experience to complete these projects on-time and within budget.
What Stephen forgets is that the problems with projects such as the subway in the 1990's happened because of political mistakes and machinations and lack of corporate construction experience. At this time with projects built under the current two management teams (Snoble and Leahy), it is unlikely to repeat some of those mistakes from the 90's, as most have learned their lessons.
The current management have met targets and budgets and there is no reason to expect anything different.
