Development Update: Week of April 6, 2020

Marriott International Headquarters

Week of April 6, 2020

Construction activities at the Marriott International Headquarters and Marriott Hotel have been temporarily suspended, but operations are expected to resume on Monday, April 6.

On Wednesday, April 1, the development team learned that two subcontractors working on the construction site tested positive for COVID-19. More than a week prior, these two individuals refrained from the site after experiencing flu-like symptoms, but in an abundance of caution, we have suspended work on the site for 72-hours to allow a third-party company specializing in biohazard cleanup to perform a deep cleaning per CDC guidelines. News of the temporary suspension of work was featured in Bethesda Magazine.

The health and safety of all those working on this project is the development team’s highest priority. In addition to these recent activities, they have proactively added additional handwashing and sanitizing stations, increased frequency of cleaning and engaged with a healthcare team to monitor the wellness of workers. The team has assured us they will continue to follow the guidance of the CDC and local and state governments to continually adapt jobsite activities throughout the ongoing pandemic.

Beginning next week, early morning work will resume with concrete placement operations beginning at 5:30 a.m. As the project advances, we anticipate early morning concrete placements to continue most weekdays through the fall of 2020.

Along Wisconsin Avenue, nighttime work continues as Pepco performs work at night on the underground utility vaults toward the north end of the construction site. Nearby, work on stormwater connections and duct banks will continue toward the south end of the construction site. Southbound Wisconsin Avenue should remain unaffected as all of this work is being performed within the curb lane.

Along the southern side of Norfolk Avenue, the sidewalk remains closed during daytime hours. However, construction on a covered pedestrian walkway will soon be finished to maintain uninterrupted pedestrian access and provide protection from overhead work. Two-way vehicular traffic along Norfolk Avenue remains unaffected.

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. The safety of commuters and pedestrians around the construction site is vitally important, so we ask that you 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.


Bi-monthly construction updates

The development team is committed to an open dialog with the community and holds bi-monthly construction updates open to the general public. These updates are generally scheduled for the first Tuesday of every other month and take place in downtown Bethesda at the Bethesda-Chevy Chase Regional Services Center located at 4805 Edgemoor Lane, Bethesda, MD 20814.

However, due to health concerns related to the coronavirus (COVID-19) pandemic, we will not be holding the regularly scheduled bi-monthly meetings until further notice. Until then we encourage you to submit any questions or comments to
