The original design for the SEC (four buildings at a cost of maybe $1.5 billion in 2022 dollars)) was radically different from what was built. When the Great Recession hit, Harvard's coffers were empty (the university was so illiquid it had to float bonds to generate cash to pay day-to-day expenses), and construction was stopped at grade, and the project mothballed. I don't recall ever seeing renderings of the interiors for the original design, so I have no idea whether the design as built was VE'd from its predecessor.
It would be a whole separate thread in another aB forum to discuss the varying strategies of Harvard, MIT, and Northeastern when it comes to spending on capital projects. For example, MIT spends boatloads of money on commercial buildings, the return on which is a key revenue source when it comes to MIT's annual budget. MIT has committed to spending $750 million on capital construction on its 10 acres of Volpe. Harvard seems content with just collecting ground rents, but is spending $1.5 billion or more on reconstructing the 'river houses'. (<< And talk about a mega-project almost entirely ignored on aB.) Northeastern lets the private sector build residence halls, and foregoes, at least for a good while, the 'cash cow' revenue stream from 'dorms'.
