Development Update: Week of February 24, 2020
NOTICE OF CONSTRUCTION ACTIVITY
Marriott International Headquarters
Week of February 24, 2020
Concrete placement operations continue at the Marriott International Headquarters construction site. Limited crews will be working this Saturday, February 22, on concrete operations as well as underground utility vaults on Wisconsin avenue. This week, large-scale concrete placements are anticipated to take place on Monday and Wednesday beginning at 5:30 a.m. As the project advances into spring, we anticipate early morning placements to continue most days through the fall of 2020.
Further south along Wisconsin Avenue, work has begun on additional underground utility vaults for the future hotel building, which includes the drilling of sheet piles to support the excavation process. We anticipate the installation of these sheet piles will result in an increase to noise and vibrations in the area.
To facilitate the installation of these underground vaults, closures will go into effect for the sidewalk, curb and southbound center lane beginning Tuesday, February 25. The center lane will be closed from 9:30 a.m. to 9 p.m., and the curb lane will be closed during the day and nighttime hours. Throughout this time, pedestrians will be detoured to the east sidewalk of Wisconsin Avenue. These work hours are intended to minimize traffic impacts during morning rush hour, as well as noise impact on the community. We expect the closure of the center lane to remain until Tuesday, March 10.
Nearby on Wisconsin and Norfolk avenues, work is nearly complete on the underground utility vaults for the future headquarters building. We anticipate Pepco to mobilize to the site in the coming weeks to install underground electrical lines in the installed duct banks and vaults.
Meanwhile, the development team continues to coordinate with the property management of neighboring buildings to ensure every effort is made to address their concerns and minimize disturbances caused by the ongoing work on the underground utility vaults, which is anticipated to continue through late spring 2020.
Throughout this project, approved Montgomery County and State Highway traffic and pedestrian control plans ensure minimal impact to traffic flow around the construction site. For available walkways around the construction site along Woodmont, Norfolk and Wisconsin Avenues, view the pedestrian site logistics plan here.
Our number one priority is the safety and security of commuters and pedestrians around the construction site. During this time, please be vigilant and pay close attention to detour signs and flagging operators as they help to ensure your safety, direct traffic, and minimize disruptions.
