The BiDWG (Crossrail BIM in Delivery Working Group) is overseeing a trial at Custom House of
using Augmented Reality technology to overlay planned construction works in the
field using an iPad.
As is shown in the photo below the
design model is positioned in real space on the iPad screen using the iPad
camera and a combination of tracking and positioning technologies.
The model has been linked to the construction
schedule so the user can step through the construction sequence in the field,
helping to identify pinch points and potential problems before the works
commence.
As is shown below the user can click on the construction
components and view the attributes stored against that component. Additionally
information,such as an installation date, can be input into the iPad
application and automatically posted back to the planning team, informing them
of the live status in the field.
The pilot is half way through an 8 week trial on
site. The pilot is capturing data on how this method of capturing construction
progress compares to the current work process. Any efficiency gains should help
to justify wider roll-out of this technology.
Thanks to the Crossrail delivery site
team for their support.
As they say, watch this (augmented)
space!
