How would you assess the availability of those with civil, electrical, chemical and mechanical engineering degrees against the upcoming need for workers in the roads, bridges, water, construction, thermal installations and other related industries in this country?

My take (as a telephone sourcer):
In my experience these individuals are highly sought and becoming ever more valuable.
They are hard to find and most of them are gainfully employed.
They are a conservative bunch and not likely to change employment without a lot of hard thinking on the matter.
More and more of these are women - especially in the younger population.
The younger population does not feel well-represented in this group to me (is this a result of less interest at the academic level in science-engineering?)
The demand is increasing exponentially.

What are your thoughts?
