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 is ongoing with decking and detailing continuing through late December. Steel beams deliveries are offloaded and installed using the tower crane. Crews are working on level 6 and 7. Level 8 and 9 will start at the end of October. Mechanical, electrical, and plumbing trades are working on site. Rebar installation continues as well as exterior waterproofing. Three concrete deck placements can be expected each week this month during regular work hours – some finishing work may extend beyond 6:00 p.m. depending on weather conditions. A pump truck will be present on South Campus Drive during concrete pours. The contractor is grading and prepping an area for the temporary construction hoist. Work includes sitework, rebar, and concrete. The hoist is expected to go up by November 18. Crews are also fireproofing at the garage level. This work will be progressing up the building next week.
- As the building grows in height, there is an increase in personnel on upper floors and on exterior staging.
- The tower crane will be in use for the next three 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.
- Neighbors can anticipate several road closures on South Campus Drive in support of concrete operations to allow for concrete pump placement and site access. All pours are anticipated to take place on weekdays during normal working hours with the road being returned at the end of each day. All signage and details will be provided to divert traffic as needed.
- Within the next few weeks, additional work will include concrete deck placements on levels four through eight, installation of material hoist and common tower (week of October 21), and exterior building wrap to retain heat (late October).
- On the new American Repertory Theater (ART) work site, a mix of excavating, backfilling, placements, footings, and walls continues. Excavation for footings and concrete operations continue with regular concrete placements. Curtainwall (the non-structural exterior building covering) is ongoing and followed by work on the brick façade. Structural slab placements continue at the lower level. On the east side, crews are starting underground electrical with placements every couple of days. Concrete placements will continue through November, with an early start necessary during the week of October 28. Structural steel will be arriving on site at the end of November.
- Please note, a large slab on grade placement is scheduled for next week on Thursday, October 17, or Friday, October 18. Because of the size of this placement, it is necessary to start work earlier than usual. The pump trucks will be set up at 5:30 a.m. and concrete trucks will begin arriving through the gate at the corner of South Campus Drive and Western Ave at 6:00 a.m. Finishing work may last until 8:00 p.m. The project team appreciates our neighbors’ patience and understanding during this necessary work.
- Ivy Lane utility work on the 12-inch drain line tie in and the 6-inch sewer tie is finished. Plates are placed over the water line taps until testing is complete. Ivy Lane will be patched and paved by end of next week. Upon completion, replacement of brick pavers will be completed on the sidewalk.
- Work continues on the building mock-ups to review design and constructability across North Harvard Street. At the ART mockup, crews are installing window and curtain wall system. Brick work and wood plating continues. Painting and caulking are complete. Adjustments continue intermittently on the housing mockup.
- The job sites will be closed on Monday, October 14, in recognition of Indigenous People’s Day.
- Miscellaneous steel and concrete work will be taking place on the next two Saturdays, October 12 and 19, on the new Harvard University affiliate housing building.
- The project’s regular work hours are Monday through Friday, 7:
