Weekly Status Summary
Due to this weekend’s forecasted high winds, the hotel crane operation must be postponed. Installation of the hotel crane for the Newbury Street site will now take place the weekend of March 25. Additional notification will go out ahead of that weekend. All other aspects of the operation will remain the same including on-ramp closure.
Install of structural steel beams and prefabricated concrete panels continued above I-90 Eastbound this past week in order to help build the deck over the Turnpike. We will continue building the overhead structure this week and for the next few months. This work can only occur at night and requires temporary slowdowns on the highway. For more details, see our Construction Updates page.
On site, interior foundation and core work remains ongoing in both the Boylston and Newbury Street parcels. The barrels that are now in place on the Turnpike Westbound are creating a safe workzone for the neighboring project to the west (known as Parcel 7 / Fenway Center).
Limited noise is expected overnight while we continue concrete wall repairs within the Mass Ave Tunnel. This activity can only occur overnight, so we will minimize and mitigate noise as much as possible. We will also continue erecting steel during second shift within the Boylston Street site.
Detailed Look-Ahead
TURNPIKE & TRAVEL
Steel/ Precast erection, Turnpike Eastbound (inbound): between 11:00 p.m. through 5:00 a.m., prefabricated steel beams and precast panels will be installed over the highway one by one. This installation will only occur overnight when periodic “rolling roadblocks” can be used along with nightly lane closures. Police will periodically slow traffic so that no cars pass under the deck while the construction crew places each beam. Turnpike on-ramps will be temporarily closed while these “rolling roadblocks” are in place. After each beam is placed and secured, traffic will be allowed to move normally.
Turnpike Eastbound (inbound): the slow-speed (right) lane workzone has now been shortened back to Charlesgate Park bridge, and is open through the Parcel 12 site.
Turnpike Westbound (outbound): the slow-speed (right) lane will remain closed from the Prudential Tunnel to just past Beacon St, now that the concrete barriers were replaced with barrels. This closure will allow for safe and continuous set-ups for Parcel 7 (the neighboring project to the west, also known as Fenway Center).
Please continue to move carefully through all workzones including the Westbound Turnpike and around local streets: pay extra attention to your speed, lane markings, traffic signage, barriers, and any police or construction workers you see.
ON SITE
Work within the Boylston Street site includes continuation of the concrete elevator core walls, slab-on-grade and deck pours, and erection of structural steel.
Concrete core operations within the Boylston Street site will be ongoing from 3 p.m. to 11 p.m. during weekdays. Noise will be limited, and we will utilize white-noise back-up alarms during material delivery.
Installation of underground utilities will continue throughout the Boylston and Newbury Street sites.
Work on site will continue within the Newbury Street parcel, including interior foundation walls and other foundational detailing elements.
OVERNIGHT WORK
Nighttime work will continue in the highway, along the railway, and within the Boylston Street site along the railroad tracks where required for safety and logistical reasons. The project is taking all appropriate steps to avoid and mitigate noise from demolition. Upcoming overnight work includes:
As detailed above, steel and precast panel erection to build the deck over the Turnpike will occur between 11:00 p.m. and 5:00 a.m. Limited noise should be expected, but installation is not expected to be loud compared to background highway noise. We will work to manage and minimize noise as much as we can.
To prepare for installing light fixtures and fire protection lines along the existing concrete walls under the Mass Ave Bridge, we will continue repairs of the existing bridge concrete walls during rail shutdowns. Because of limited windows for rail track access, this operation will be completed overnight. Minor noise is expected within the tunnel, and we will remain diligent about providing mitigation measures to control the impact to the neighborhood.
Installation of electrical equipment along the new foundation wall adjacent to the rail tracks and the Boylston St. parcel will continue.
Loading and unloading of the construction area at the Newbury Street on-ramp will continue overnight and in the early morning to support the ongoing foundation activities.
Always check the Construction Updates page for the latest information and scheduled activities. Workhours are coordinated with MassDOT and with MBTA and are subject to change based on weather.
OTHER NEARBY WORK
Construction and maintenance work unrelated to this project continues in the area. This includes local utility and street work, rehabilitation of portions of the Dalton Street bridge and nearby highway barriers, other construction projects along I-90 and in the neighborhood, and routine road maintenance. These other construction activities may have noise and/or traffic impacts that are not covered in these BuildP12 project updates. We will strive to provide information about these as a courtesy wherever possible.
