Weekly Status Summary
Interior foundation and core work remains ongoing in both the Boylston and Newbury Street parcels. Next Monday night 1/10, we will install the remaining deck planks over the rail tracks using an overnight rail shutdown. The work is scheduled overnight to minimize disruption to passenger service. On the highway, barrier install is nearing completion and preparations for overhead structure are ongoing. Limited noise is expected overnight for restoration of the Turnpike as we continue preparations to remove the barriers within the Eastbound and Westbound slow lanes. We will continue erecting steel during second shift within the Boylston Street parcel.
TURNPIKE & TRAVEL
Turnpike Eastbound (inbound): slow-speed (right) lane remains closed from the Allston Viaduct (the Exit 131 interchange) to just past Mass Ave.
Turnpike Westbound (outbound): slow-speed (right) lane is closed from the Prudential Tunnel to just past Beacon St. This extended closure allows safe and continuous set-ups for Parcel 12 and for the neighboring project to the west, called the Fenway Center.
Overnight single-lane closures are expected on the Turnpike, requiring closures of the Newbury Street on-ramp. We will post dates on Construction Updates once confirmed by MassDOT.
The second stage of deck support wall construction is nearing completion on the Turnpike. The foundation walls on both sides of the highway have been fully poured, and we are completing install of highway barriers as well as tunnel mechanical systems.
Concrete wall repairs: within the Eastbound Turnpike workzone and under the Mass Ave Bridge, we will continue chipping and repairing the concrete wall. Noise is expected and this work will be limited to daytime hours. Westbound repairs are complete.
Please continue to move carefully through the workzones: pay extra attention to your speed, lane markings, traffic signage, barriers, and any police or construction workers you see.
ON SITE
Mass excavation and interior foundations throughout the Boylston Street site are complete. Work on site includes continuation of the concrete elevator core walls and below-grade 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 plumbing and electrical will continue throughout the Boylston and Newbury Street sites.
Work on site will continue within the Newbury Street parcel, including interior foundations and preparing to begin the concrete elevator core walls.
Preparations to erect the Newbury St parcel tower crane will continue during this period.
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:
We will install the remaining deck planks over the rail tracks using a weeknight closure on Monday 1/10 as included in previous emails. The work is scheduled overnight to minimize disruption to passenger service. The MBTA will use an overnight shutdown of the tracks for safety during installation of the beams. For Commuter Rail information, follow MBTA Service Alerts at @MBTA_CR on Twitter, mbta.com, and the Transit App.
During deck installation, we will also prepare to install light fixtures and fire protection lines along the existing concrete walls under the Mass Ave Bridge. In preparation, we have begun repairs of the existing bridge concrete during the rail shutdowns. Noise is expected as this work is completed, limited to daytime hours.
Installation of electrical equipment along the new foundation wall adjacent to the rail tracks and the Boylston St. parcel will continue.
Restoration of both slow-speed fixed workzones will continue this week: removing fence panels and general clean-up. Minimal noise is expected.
Removal of material and loading of the workzone will continue overnight within the Turnpike workzones in both directions. This work requires travel lane closures that cannot occur during the day.
Loading and unloading of the construction zone 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.
