Re: South Station Tower
couple of edits;
Pardon, i'm pretty lousy with notetaking... Fascinating, detailed discussion about distributing the loads by means of various arches to work off the 8 main columns between each track, and the creation of a unique lobby/rail-to-city gateway/public space below. i appologize for not having more detailed information about the structural side, save for the change to reinforced concrete to make the upper tower much more stable.... but, the increased weight + the absence of being able to locate the piles/columns to suit) + height and massing they'r working with, leads quickly to arches.
(This should make for a lively discussion on Archboston).
BCDC appears to generally support the new tower design, but giving perhaps greater enthusiasm to the overall project, and the public use aspect. Andrea likes/loves everything (no surprise) except for showing concern about the arch system.
–which leads to my surprise there's no discussion of a truss system at the base.
There appears to be a lot of complexity here.
"When we do come back...." BCDC want's to see more detailed (larger?) models of the project and... and...."
*BCDC commissioners repeating concern about the arches at the base.
i asked Mr. Clarke if they had considered the usage of a truss down low - which opened a wormhole and brief discussion about the complexity (re; $$$) of the rather heavy (stiff) concrete working with that type of structure.
When i read Logan's SST stories in the Globe, or the brilliant commentary here, the idea of Millennium Tower height at South Station is more hard to believe. Then you see the presentation and makes it's much more real (despite the urgency with time).... but MT, 111 Fed , GCG, TD Garden and the Garden Garage projects give a lot of confidence. SST looks ok from some of angles. Given the apparently great complexity on the structural side than i had previously considered - i have an attitude adjustment to 'happy if Hines/Pelli Clarke Pelli pull it off.'

Too bad Boston didn't get....
*1:50 am; i see it now. a stiffer, heavier building + going over tracks that are probably a bit too close together (for a design that was originally going to be steel) + VE leads inevitably to arches.
