Oh I get what you are saying. As an architect, I can't tell you how many times I've seen scope reduced because someone was pinching pennies. Of course, deferring maintenance only costs more money down the road. As to the appearance of the new shell, I would agree with you on this as well. They should have gone totally modern or should have made more historical gestures to better align with the original style. And just as with the concrete repair, this too, to my eye, looks very much like another budget concession. I think the shell looks like just about the cheapest way they could have clad the original building.
In fact, right now I am working on a project that is soon to start construction. We have been working on the planning and design for over a year. But with 7 weeks before design completion, they want to cut 10% off the costs. And oh, don't change the schedule.
