When I did my height estimates above for the 3 tallest Transbay towers, there were a number of points I estimated or guessed that are possibly consistent with the planners, in addition to the data I collected from different sources:

· · Planners are releasing information in careful steps to test outside reaction. If little or no negative reaction is encountered, the planners move up to the next step until the best overall plan is achieved.
· · Graphics may show intentions more accurately than verbal descriptions.
· · A shift of emphasis in the SF skyline should be shifted to the area around Transbay by creating a new highest mound of towers at that location.
· · To achieve the shift, key buildings should be at least as tall as, or taller than current tallest building in SF - Transamerica at approximately 850’.
· · It would take at least 3 towers to effectively create a highrise mound that steps down to the surroundings.
· · Basic building heights are rounded to the nearest 50’.
· · Basic floor-to-floor heights are averaged to 12.5’.
· · Basic crown/mechanical heights are 10% of the basic building height rounded to the nearest 25’ added on top of the basic building height.
· · Number of floors are rounded to the nearest 10 (or 5) depending on the basic building height.
· · Basic height difference of towers above 850’ are probably greater than 150’.
· · Heights of tallest towers should be varied to create a more interesting stepped height effect. No two major towers should be nearly the same height.
· · The difference in height between the tallest and second tallest tower is greater than the height difference between the second and third.


(Old news we may have missed) Regarding the competition:

The two-stage competition will be launched in the fall of 2006 and is expected to take approximately 36 weeks for completion.
"Fall" could mean anytime before December 21, 2006. We could have preliminary designs submitted by contestants by August or September of 2007, depending on when the competition commences. A final design that could end up being very different from the original will be developed and refined by the winning design team until final documents completed and approved. This could be as late as 2010 depending if there are other unkown factors that could shorten or lengthen the time. Note that final heights can also change until approvals and permits are granted. Normally, this could be about 3 months before construction begins, but for these projects I am not certain. I imagine the design for the temporary terminal might be a separate contract, and the designer may be sought for more directly by the city or TJPA.


Of all the uncertainties, one thing is clear: we still have a very long way to go before anyone knows what the final result will be. Just think of One Rincon Hill. By the way, remember this? Is wasn't all that long ago...
