Development Update: Week of November 5, 2018

Marriott International Headquarters

Week of November 5, 2018:

Construction of the Marriott International Headquarters development site continues, including equipment and material deliveries, environmental and safety controls, excavation, hauling and drilling operations.

On October 31, the sidewalk in front of the 7750 Wisconsin Avenue project was closed with the curb lane available as a pedestrian walkway. This closure facilitates the installation of support of excavation and earthwork activities. We anticipate the closures to remain for an extended period of time through project completion. Pedestrian access will be maintained during all non-work hours and weekends and as much as possible during work hours. As a safety precaution, pedestrians may be periodically detoured to the sidewalk along the eastern side as necessary.

Additional lane and sidewalk closures remain in place along other sections of Woodmont, Norfolk and Wisconsin Avenues (view map of closures here). These closures provide access for construction activities, as well as safe pedestrian passage. As a reminder, please pay close attention to signage and flagging operations as conditions may change from time to time. We ask for your patience during periods of inconvenience. Our number one priority is pedestrian safety in and around our project site.

We are aware of an increase in early morning truck staging activity prior to construction hours, particularly along Woodmont Avenue. The developers are working with local officials to minimize any disruption to nearby residents and businesses. We are also aware of trucks departing the development site, and along with other local vehicular traffic, causing traffic congestion on Norfolk Avenue turning left onto Wisconsin Avenue. The developers are actively working with officials to improve these operations, including adjustments to signaling systems, which will improve efficiency for both vehicular and pedestrian traffic.

Last week’s scheduled Pepco outage, which took place between approximately Sunday, Oct. 28 at 10:00 p.m. and Monday, Oct. 29 at 6 a.m., was successful as contractors were able to complete necessary electrical work. Any future anticipated and scheduled disruptions or outages required for the Marriott project will be expressly communicated with all stakeholders beforehand. It is anticipated that another outage may be necessary on or about November 16.

Finally, we remind residents and businesses in the surrounding areas that there are several other unrelated projects underway near the Marriott development site, including work being performed by WSSC, Washington Gas and their third-party contractors. We are aware of a few reported disruptions to nearby residences and businesses; however, these disruptions are completely unrelated to the Marriott project.
