Demolition on the Amazon HQ2 site in Pentagon City is expected to begin soon.

The 2.1 million square foot office-and-retail development along S. Eads Street, the first phase of Amazon’s permanent second headquarters in Arlington, was approved by the County Board in December.

Now, construction equipment is being staged ahead of demolition of the two-story warehouse building and parking lot currently on the site. According to an off-the-record presentation given to local civic associations earlier this week, a slide from which was obtained by ARLnow, demolition and site preparation is scheduled to start within the next month or two.

Excavation will run from the second quarter of 2020 to the end of the year, while construction of the above-ground portion of the complex is expected to start in the second half of 2021. Construction and interior work is expected to wrap up by the middle of 2023, according to the presentation.

In the meantime, the growing contingent of Amazon employees in Arlington will work out of temporary office space in Crystal City.

“We’re looking forward to beginning demolition at the Metropolitan Park site in the very near future; some staging activity has already begun,” an Amazon spokeswoman told ARLnow. “Amazon is already here and we’re hiring. As the MetPark site takes shape, we will continue to grow the teams in our leased space in Crystal City, where we now have nearly 450 employees.”

It’s not yet clear whether Amazon will hold a groundbreaking ceremony as work at the Pentagon City site gets underway.

Some local residents, particularly those who live in apartment buildings across the street, have expressed concerns about construction noise from the project. Permitted working hours extend until 9 p.m. on weekdays, we’re told.
