Development Update: Week of May 4, 2020

Marriott International Headquarters

Week of May 4, 2020

As structural work on the eighth floor is completed today, an overhead protection plan has been fully implemented. This includes cantilevered nets above the site and floor-to-floor netting overhead pedestrian areas. Along Woodmont and Norfolk Avenues, new walkways allow for uninterrupted pedestrian access with overhead protection throughout the duration of the project.

Repairs are ongoing to Pepco conduits between underground vaults under the center lane of Wisconsin Avenue and the new Marriott Hotel. This work was delayed due to rain but is expected to continue through this week as weather permits. Pepco will continue performing utility work during nighttime hours. This also includes repairs to the Wisconsin Avenue median curb, which are being coordinated with SHA.

The curb lane and sidewalk of southbound Wisconsin Avenue remain closed, but additional lane closures are anticipated soon as an external hoist and dock are installed in preparation for the installation of the curtain wall. This is anticipated to be completed in late May.

Meanwhile, early morning work on weekdays continues as delivery and placement of concrete and rebar begin at 5:30 a.m. We anticipate this work to continue most weekdays through the fall of 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. 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
