Lot I / 23-24 September 2020

Surprise! The core has risen above street level prior to pouring the bathtub (and with the lateral bracing struts in place).

Methinks DivCo wants to motor prior to the sloppiness of late fall (or COVID-19, round 2).

From 23 Sept, evening:


From 24 Sept, morning:

Lot I / 16 October 2020

The core is at the eleventh floor.

As a refresher: This building will include 21 usable floors, be 250-ft tall at the top of the mechanical screen, and include an 18-ft fire monopole. For reference, the screen height is 13-ft taller than Twenty|20's screen pinnacle.

250 feet... If any building exemplified how off the neighborhood-making process is here it's this one. This is in the crown jewel spot of the neighborhood- it could be double the height, prominently designed, and not have any NIMBY impact complaints. The master plan cut out its knees before it could even make a case.

How do they "do" an isolated body of water like the one shown below? Is it totally pumpy-aerator-fakey? Runoff? Millers River? Reclaimed greywater? how do they keep it from silting up?

I am glad they chose a park to anchor the neighborhood. There can never be too many parks imo. This is actually more "park" than "square plot of grass" like the seaport too, nice to see.

In defense of the seaport the harborwalk more than makes up for it and seaport sq will be a hit. Just as a frame of reference though I think this is a much better design. There is no harborwalk here so you need a better park to anchor the area.

I normally think they should go higher in Cambridge but I'm actually alright with the heights here. I was down there on Thursday and was impressed with what's going on.
If you double the height of this building you run the risk of unbalancing the overall look of the neighborhood. And if you bring up the height of the overall neighborhood, you run the risk of over doing it.
I know it's a public transit oriented development but a lot of people will still want to drive and It's fairly hemmed in by existing infrastructure. The rendering you've posted looks pretty good to me and they seem to actually be heading in that direction unlike a lot of renderings you see.

Quick update: Lot I's tower crane components are being delivered today. Too bad I can't upload time lapses: I shoot a lot of them of our CX construction and the crane construction ones are spifftastic.

The building's core reaches to (above grade) level 13.

I will post static images later.

There's probably some liner or something under it all. The rocky portion in front of the 2 story gable building in the back is already in place and filled with water.

It probably works similarly to this better known man-made isolated body of water:

Lot I / 20 October 2020

Looking north beyond Lot W (housing the now open Cafe Beatrice). Crane segments began arriving around lunch and the installers worked until 1800.



These dudes were rockin' the view from ~33m.

Looks like it's part of a larger storm management system, it's basically a retention pond. I found this from of a 2017 water testing report (public info EPA report).

Some of my historic posts on the main CX thread show the new floodwater mitigation system installation beneath the drumlin south of Lot W. Low throughput pumps circulate the water, but honestly high winds do more to break up surface frog kaka than those systems.

I can add some images later if they are difficult to locate.

A small earthen dam separates the two ponds, which have existed since 2008 (the walkway "bridge" is only for show). A portion of the park (near Lot N) is below grade and has semi permanent water for much of the year. If you're uncertain of its location, it is the (surprisingly pretty) bog with cattails and the tallest trees in the park...I don't know what the plan is for the zone, as the orange fences surrounding it are ghastly.

Lot I / 23 October 2020

Crane installation finished yesterday afternoon. Site crewmembers have been calibrating and testing it since then. The climbing apparatus is at the base of the crane (first time I have seen that).

The residential building core is at level 15 (of 21) above grade, or about 160-ft of 250-ft.
