The real work is going on inside Wrigley Field, where the lower-deck seats from dugout to dugout have been removed in order for them to begin digging out the foundation for the future 1914 Club, which is scheduled to open in 2018. I'm sure you've seen those aerial shots elsewhere and I'm sorry I can't add to them here.
Still, there's a lot going on along the exterior of the ballpark that is visible from the street, and I present to you a photoset I took Friday afternoon.
They're progressing quickly along the exterior of the plaza building, as you can see in photos 1-4. It looked like a lot of sealing up of windows. The exterior of the building ought to be finished quite soon, and then they can complete the interior for the team's planned move of offices, which is supposed to happen before Opening Day.
There was a large crane on the field (photos 8 and 9), though a lot of the digging on the field itself appears to have finished (photos 11-12-13). The south face of the ballpark along Addison is now pretty much tarped up (photo 18), and there was quite a bit of noise in that area, though I couldn't tell exactly what was going on.
Other than that, there seemed to be several dozen workers in various areas of the park, so the work seems to have been ramped up to a high level. They're still flying the "W" over the scoreboard (I suspect that stays up all winter) and the marquee, now decked out in holiday decorations, still says "WORLD SERIES CHAMPIONS" -- that can stay up all winter too, as far as I'm concerned. Even on a cold Friday afternoon there were still quite a few people taking photos on the opposite side of Clark Street with the marquee in the background.
We'll continue to update the project over the next weeks and months.
