I have Estmating experience, bidding experience and also designing experience. also on some projects i am project manager for conceptual engineering.
I may be wrong, but many times I wonder, if engineers would give a thought to cost$$ when they design, things would be different. I know safety is the utmost important thing, but there is always room for Value Engineering and optimizing the design so as it exceeds the safety design requirements but is also economical. If every engineer thinks in terms of cost, i feel tax payers money can be saved and put to a better use somewhere else...
my two cents
