Pile driving for Amazon’s $2.5-billion HQ2 project in Arlington, Va., finished two weeks ahead of schedule and construction officials say concrete work will begin this fall, pending approvals.
On April 15, crews began driving 330 piles, each measuring between 60 to 70 ft in length, to provide temporary support of the excavation site at Amazon’s Metropolitan Park campus. The work was expected to require six weeks to complete, but instead wrapped up on May 15, according to a spokeswoman for Clark Construction Group, the project's contractor. “It was a good outcome to a challenging effort," she said.
