Abstract
A method for tracking progression of a construction site at different points in time relative to an expected progression of the construction site as represented by a computer model. The method includes generating an image of the construction site by scanning the construction site with an imaging device and detecting a fiducial marker appearing in the image at a location on the construction site. The fiducial marker is unique among fiducial markers positioned on the construction site. The method further includes identifying the detected fiducial marker in association with a unique identifier among the fiducial markers and aligning a coordinate system of the identified fiducial marker with a coordinate system of the computer model, which represents the construction site at points in time.
