Construction Update

(Update February 28: Due to expected extreme high winds on Saturday, March 3, there is a possible delay on the temporary closure of 20th Street NW.

If high winds occur as forecasted, the 20th Street NW closure (from S Street NW to Florida Avenue NW, from 7:00 a.m. to 7:00 p.m.) will be postponed until Sunday, March 4 or Saturday March 10, 2018. We will keep you updated as we receive more information.)

On Saturday, March 3, 20th Street NW will be closed from S Street NW to Florida Avenue NW from 7:00 a.m. to 7:00 p.m. A mobile crane will be used to place the Dedicated Outdoor Air System (DOAS) equipment on the roof of the AGU building. The DOAS unit is a large component of energy recovery being installed as part of the project. This street closure is necessary to complete this aspect of the project.

Please be aware of the following details of the work:

  • Parking on 20th Street will be restricted 72 hours in advance on both sides of the street;
  • The sidewalk will be closed on 20th Street in front of the AGU building only;
  • 20th Street will not be accessible by vehicles between S Street and Florida Avenue, except for local traffic, which will have access to the 20th Street alley via S Street and 19th Street; and
  • Normal vehicular traffic will use 19th Street as a signed detour.
  • Entrances to apartment buildings opposite the AGU building on 20th Street will not be impacted during this time.
  • Glen’s Garden Market on 20th Street will be open during normal business hours and accessible by foot during this period of work.

Additionally, on or around the week of March 5 or the week of March 12, neighbors will notice some overnight lights and noise from a generator at the corner of Florida Avenue and 20th Street at the AGU site for two to three days.

The construction team will be completing bypass work inside the sewer to install the necessary equipment for the municipal sewer heat exchange system. D.C. government’s regulatory requirements will necessitate that a bypass pump be used overnight to monitor the sanitary sewer main during this work to prevent an overflow and protect the neighborhood from experiencing any interruptions. The system is a key design feature required in the design of this project for the building to reach its goal of net zero energy.
