Marriott International Headquarters

The Latest Construction Update
Week of November 16, 2020

Following the topping-out of the office building, which will become the new Marriott International Headquarters, several major pieces of the construction are now complete.

Concrete operations have concluded, with only minor concrete work being completed on the rooftop. We expect concrete truck traffic will be dramatically reduced. This week, roofing and miscellaneous steelwork is scheduled to begin and is anticipated to continue through January 2021. Additional work on the roof is expected to conclude by 9:00 p.m. each weekday evening.

Along Woodmont Avenue, underground street work on telecommunications duct banks has also concluded, with only the installation of telecommunications lines remaining, which is anticipated to last through the end of the year. Additional underground work on Woodmont Avenue to facilitate pedestrian signaling near Garage 11 is also nearly complete, and a coordinated access plan for the Bethesda Place garage is being implemented.

Meanwhile, deliveries and installation of curtain wall and glass continue, which rises along the exterior façade of both buildings, and now reaches the 15th floor of the office building. Inside, the installation of mechanical, electrical, and plumbing work continues.

The Development Team would like to bring your attention to the bike lanes being constructed by Montgomery County DOT. This work will help create a bicycling network through downtown Bethesda. Construction is expected to last three months. To learn more, visit Bethesda Magazine.


Virtual Community Meetings

The development team is committed to an open dialog with the Bethesda community and holds monthly virtual community meetings that are open to the public, where you are invited to join the team online for a live presentation and Q&A of the latest construction updates.

Our next virtual community meeting will be held Tuesday, December 1, at 6:00 PM EDT. Please join us online at that time by selecting this link.

Your Safety Around the Construction Site

Throughout this project, approved Montgomery County and State Highway traffic and pedestrian control plans ensure minimal impact to traffic flow around the construction site. Along Woodmont and Norfolk Avenues, walkways with overhead protection now allow for uninterrupted pedestrian access throughout the project. Pedestrian access is now aided by wayfinding signage at the entrances of these covered walkways. Along Wisconsin Avenue, pedestrians are redirected to use the east sidewalk for their safety. Access along the west side has been closed following State Highway approvals. 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.
