I'm *hoping* that the adults are watching the cookie jar on this project and will not allow cost overruns.

This is not quite correct. $955 million was their bid price. $1.08 billion was with contingencies added on.

The $955 million included the additive options, then the MBTA added on a $125 million contingency amount to protect against cost overruns and unexpected expenses. Fairly standard in construction.

So, did we officially get a Notice to Proceed?
[EDIT]
Yes, we've got a Notice to Proceed!
https://www.mbta.com/news/3239
Dec 21 - BOSTON - The Federal Transit Administration today informed the MBTA Green Line Extension (GLX) Project Team that it has released the first $100 million installment of the total approved $1 billion in federal funding for the 4.7-mile light rail line from Cambridge to Medford, marking another milestone for the project. With federal funding in place, the MBTA issued the Notice to Proceed to GLX Design-Build team, GLX Constructors. After a sealed price opening last month, GLX Constructors won with its bid, a total of $1.08 billion.

From my trains this week, I saw that there were crews around the BET surveying and marking the location for more GLX pylons.

The winning proposal from GLX Constructors has been posted on the GLX website. The losing bids are too.

Lots of work going on over and around the Fitchburg line and Grand Junction. It looks like they've been drilling for where various piers will continue to be built. Lots of orange circles and other sprayed markings. They've also re-aligned at least the inbound Fitchburg line onto what looks like will be its final position, and connected the Grand Junction to it, instead of the double crossover.

I recall all the disagreement with the reconfiguration from the diamonds to the ladder switches and the legitimate complaints about how the new setup will hamper the engine house moves by shortening the leads. I am curious about why they didn't go to slip switches here. Wouldn't that have been a much better solution?

Update from the vicinity of the Ball Square and Magoun Square stations:
- The turnout for the freight track has been removed
- The signals for that interlocking have been covered over and turned sideways
- All trees and brush have been cleared from the east side of the ROW (they're going to do the other side later this summer, I think)
- This morning, they appeared to be working on pulling up the freight track and the stub of the Freight Cutoff

I note that they somehow neglected to mention they were going to clear out all the trees at the various neighborhood meetings over the years. :-) Apparently they're mostly invasive species like Norway maple.

They're using the Ball Square Garage property (future site of the station) and the driveway behind Rogers Foam on Central St for access. Saw a tree-removal company truck with Hy-Rail gear go by on Medford St last week.
