How would you have structured the owner’s board of directors on the Big Dig to ensure the best possible expertise? As noted by a former Big Dig Board Member: ‘‘perhaps an owner’s board should have been established with professionals in the field of engineering, finance, construction and transportation with the sole purpose of providing checks and balances and reporting to the public. The board would challenge engineering decisions in the very early and most critical stages of the project. It would certainly be expensive to compensate this board, but, no doubt, well worth it.’’ How would you assess the value of such a board?
