About this app

tarcus brings a building's floor plans, drawings, 360° photos, 3D models and notes to the phone, for the people who work on site.

FLOOR PLANS AND 360° PHOTOS
Open the building and the floor you are on. Every 360° photo has its spot on the plan; tap a spot to look around it, and back through the earlier rounds. Take a new 360° photo with a RICOH THETA or an Insta360 camera connected over its own Wi-Fi: it lands on the spot you tapped. Faces are blurred on the phone before the photo is kept.

DRAWINGS
Every drawing of the project, in the same folders as in tarcus on the web. Search by sheet code or name, step through a folder sheet by sheet, and zoom in as far as you need: the drawing is read from its original PDF, so small text stays sharp.

THE 3D MODEL
See the building's IFC models in 3D, drawn by the phone itself, or the plan and the model together: tap the plan and the model walks you into that room. Cut sections and measure lengths, heights and areas in the model.

NOTES
Press and hold the plan or the model to leave a note where the problem is, with a photo from the phone's camera. The note reaches the team in tarcus at once, and you see its status when it changes.

WITHOUT A SIGNAL
Keep a building or a folder of drawings on the phone and it opens in a basement too. Photos and notes taken without a signal wait on the phone and are sent when it is back.

tarcus needs a tarcus account. Your organisation's administrator invites you from tarcus on the web.
