The difference is, we place "hot spots" for each photo and mark them on a map or architectural plans which have grid lines and etc as reference points. Clients have access to the photos through our website or mobile app. Through the app they take their own photos, pin them and write notes/comments for other users to see.
Here's an example of the Site Survey for a current job site. They are tearing down the building in the middle there. They asked us to take photos of the sidewalks and neighboring properties in case of any existing or new damage takes place.
Construction documentation has really only started becoming more popular within the last 5 years or so. Most of the big name contractors (Polygon, Bosa, Onni, Ledcor) now have us on board for every job. We're also doing work for the City of Surrey, Coquitlam, North Van, Vancouver. People are starting to see the value in having us for their project.
