Most importantly this weekend, a notice went out to the community yesterday describing the crane operation planned for Saturday and Sunday to hoist generators to the roof. After consulting with the Boston Transportation Department (BTD), the City required some timing and logistics changes to the contractor’s plans as follows:


  • On Saturday, August 23, the generator trailers will arrive on site between 12am-12:30am and will be staged inside the 421 Park Drive loading dock. The crane will begin to arrive onsite in sections starting at 12:30am and the contractor will begin assembling the crane then. Given the size of the crane, this process takes about 8 hours.
  • Once assembled, the contractor will hoist and install three generators to the penthouse level beginning at 8:30am on Saturday.  This work is expected to last until 12pm, after which, the contractor will start to break down the crane boom, working until 2pm – the time BTD requires that they be off the road due to an event that evening at Fenway Park. 
  • On Sunday, August 24, from 4am to 2pm, the contractor will continue breaking down the crane and removing it from the job site in sections along with the crane pad. The 421 Park Drive loading dock will reopen once the crane has been removed by 2pm on Sunday.
  • Per BTD, the contractor is required to maintain two lanes of traffic on Fullerton Street during this operation so the road and sidewalks will remain accessible to vehicles and pedestrians during this work. To keep Fullerton open, the crane will need to block two of the three lanes into the 401 Park Drive garage. Once the crane’s boom is erected on Saturday by roughly 6am, the two blocked entrances to the garage will be available to the public. The two lanes will then be closed again on Sunday from 4am to 8am while the boom is removed. There is a possibility, if all of the hoists go as planned, that removal of the boom can happen between 12pm and 2pm on Saturday.  If so, the garage lanes would be closed during that timeframe and there will be one exit/entrance lane open at the garage entrance.
  • Neighbors can expect some intermittent noise from the truck deliveries and presence of crews during the hours noted. Some lighting on the Fullerton Street side of the job site will also be needed to support this work as well. 
  • The contractor will do everything possible to minimize the impact of this crane operation on the community.
  • Pedestrians will be routed to the Atrius Health side of the street during the crane work.


Work to install curtain wall on the building’s west elevation is complete and the contractor will be installing an air vapor barrier (AVB) at this location early next week. 


Interior work continues on all levels on weekdays during regular work hours. Work will continue to install fascia panels using swing staging as well as waterproofing work during second shift (2:00 p.m. to 10:00 p.m.). This work is quiet and should not be noticeable to the surrounding community. 


Roof installation continues working from the north portion of the building to the south. The contractor is also installing planters and soils on the MBTA path side of the building using a crane.

There will be a crane on Fullerton Street each day from Wednesday, August 27, through Friday, August 29 from 7am to 5pm. Fullerton Street will remain accessible to vehicles and pedestrians during this work. 


Landscaping on the MBTA path side of the building continues. The temporary fence along this path has been shifted west and will remain in this location through October while landscaping work along the path is completed.


Landscaping work on the Atrius Health garage side of the job site is expected to take place until mid-to-late September. To accommodate pedestrian traffic during this time to and from Brookline Ave, a new temporary walkway is in place on the construction side of the street. As noted above, on Saturday, August 23, the walkway will be re-positioned to run along the job site fencing opposite the Atrius Health garage to allow landscaping work to continue. On Monday, August 25, pedestrians will be re-routed to a temporary path on the garage side of Miner Street to accommodate a concrete pour of for the sidewalk between 7am and 9am. Some saw cutting on the sidewalk will take place on Tuesday and Wednesday, August 26 and 27.

August 21, 2025

In recent communications, it was noted the contractor at 421 Park Drive would be positioning a crane on Fullerton Street this weekend to hoist generators and other materials to the penthouse level of the building from 8am to 8pm on both Saturday and Sunday. After consulting with the Boston Transportation Department (BTD), there are some time and logistics changes to this work that are required by the City, and we want to share them for your awareness.


  • On Saturday, August 23, the generator trailers will arrive on site between 12am-12:30am and will be staged inside the 421 Park Drive loading dock. The crane will begin to arrive onsite in sections starting at 12:30am and the contractor will begin assembling the crane then. Given the size of the crane, this process takes about 8 hours.


  • Once assembled, the contractor will hoist and install three generators to the penthouse level beginning at 8:30am on Saturday. This work is expected to last until 12pm, after which, the contractor will start to break down the crane boom, working until 2pm – the time BTD requires that      they be off the road due to an event that evening at Fenway Park. 


  • On Sunday, August 24, from 4am to 2pm, the contractor will continue breaking down the crane and removing it from the job site in sections along with the crane pad. The 421 Park Drive loading dock will reopen once the crane has been removed by 2pm on Sunday.


Per BTD, the contractor is required to maintain two lanes of traffic on Fullerton Street during this operation so the road and sidewalks will remain accessible to vehicles and pedestrians during this work. 


In order to keep Fullerton open, the crane will need to block two of the three lanes into the 401 Park Drive garage. Once the crane’s boom is erected on Saturday by roughly 6am, the two blocked entrances to the garage will be available to the public. The two lanes will then be closed again on Sunday from 4am to 8am while the boom is removed.

Neighbors can expect some intermittent noise from the truck deliveries and presence of crews during the hours noted. Some lighting on the Fullerton Street side of the job site will also be needed to support this work as well. The contractor will do everything possible to minimize the impact of this crane operation on the community. 


The project team is appreciative of the neighborhood's patience and cooperation during this necessary work. The community will be pleased to know that this is expected to be the project’s final weekend after-hours crane operation.
