A video showing 10 years of building work associated with a memorial museum on the site of the former World Trade Centre in New York has been released.

Last week, US-based webcam content services provider EarthCam released a10-year time-lapse video showing work on the 9/11 Memorial Museum – for which Australian building giant Lend Lease acted as construction manager – following the project’s completion earlier this month.

In a note accompanying the video, EarthCam founder and chief executive officer Brian Curry said he personally installed a camera days after the September 11 attacks unfolded in order to capture the rescue and recovery effort, and that further cameras were added over time as the rebuilding and construction phase kicked into gear.

“This commemorative time-lapse honours the victims of 9/11 and is dedicated to their families and friends, with special gratitude to the first responders and the steadfast construction teams,” Curry wrote, adding that the rebuild of downtown New York had been a ‘heroic effort’ and that the team had now maintained webcams on the site for more than 4,600 days and had chosen from more than one million images in preparing the video.

“I hope this time-lapse serves as a way to recognize that for the 10 years of construction, there was constant progress made to rebuild these important 16 acres of America.”

The video’s release follows the opening of the museum, which is located on the western edge of the World Trade Centre Memorial site and will display monumental artefacts linked to the events of both 9/11 and an earlier 1993 attack as well as presenting stories of loss, compassion, reckoning, and recovery and documenting and exploring the impact and continuing significance of the attacks. The museum opened following a dedication ceremony on May 16 at which US President Barack Obama said those who visited would find it a “profound and moving experience.”

The museum sits on the same site as the September 11 Memorial, which was completed several years ago and which opened on the 10-year anniversary of the attacks.
