175 North Harvard Street Project Construction Impacts Update
The following is an overview of the work taking place at the 175 North Harvard construction site at the
future location of the new Harvard University affiliate housing building and American Repertory Theatre
(ART):
- The structural steel phase of the housing project remains ongoing. Decking and detailing continues through December. Steel beams deliveries are offloaded and installed using the tower crane. Mechanical, electrical, and plumbing trades are on site working on under slab utilities. Rebar installation continues and several concrete placements will take place each week during regular work hours – some finishing work may extend beyond 6:00 p.m. depending on weather conditions. The contractor will be working on grading and prepping an area for the temporary construction hoist. Work will include sitework, rebar and concrete.
- There will be an increase in personnel on upper floors and on exterior staging as the building grows in height.
- The tower crane will be in use for the next four months during normal working hours and will be placed in weathervane mode with safety lighting turned inward at the end of every shift.
- Wheel washing and street sweeping continues to ensure soil is not being tracked through the neighborhood streets.
- Road closure of South Campus Drive may be required mid-week for a small concrete pour due to the ongoing utility work in Ivy Lane. In the event that a road closure is required, the team will coordinate signage and police details as needed.
- Within the next six weeks, concrete deck placements on levels two through five may require some extended hours. More details will be provided as the date gets closer.
- On the new American Repertory Theater (ART) work site, backfilling is ongoing in the substage area. Plumbing work continues in preparation for slab on grade work. Formwork and waterproofing will be ongoing and tie-ins for the mat slab work have started. Excavation for footings and concrete operations continue through the rest of this month with concrete placements every couple of days. Curtainwall (the non-structural exterior building covering) will begin this month and then the contractor will start working on the brick façade. Structural slab placements start mid-September at the lower level. On the east side, excavation for footings and concrete operations continue through the rest of this month with placements every couple of days. Then crews will excavate for the foundation and backfill.
- Utility work began last week on Ivy Lane on the 12-inch drain line tie in and two water taps for the domestic and fire protection lines. Work will take place during regular work hours and will continue until September 27. The road will be plated overnight. Next week, storm drain work will take place until the end of the month. The contractor will be implementing intermittent closures of Ivy Lane to through-traffic, always maintaining access to the Continuum garage and loading dock. All thru-traffic will be sent to South Campus Drive. HUPD officers are directing traffic. Teams will be coordinating to maintain traffic control during Ivy Lane and South Campus Drive-related activities.
- Work continues on the building mock-ups to review design and constructability across North Harvard Street. The curtain wall for the mock-up will be delivered and installed next week followed by the brick facade.
- There is no work planned on site for the next two Saturdays, September 14 and 21.
- The project’s regular work hours are Monday through Friday, 7:00 a.m. and 6:00 p.m. and Saturdays as permitted by the City of Boston from 7:00 a.m. to 6:00 p.m.
