Building survey solution for professionals

Renovating a small flat with OrthoGraph in Budapest

We had been tasked to renovate a small, 36m2 flat, located on the 7th floor of a block built in the early 80s. We decided to use OrthoGraph to conduct an initial site survey, and use the resulting building documentation to aid us during the different work phases.


1. As a first step, we did a throughout survey on the flat.
We used a Leica D510 laser distance meter, and the iPad/Android tablet based OrthoGraph software. In a matter of minutes we were done with the building model, which we exported into a PDF roombook and an Excel sheet, so that we could pull them up anytime we needed their data during our job. OrthoGraph allowed us to determine the different surface areas of the flat, and we could also highlight and documented the wall cracks/problematic/to be replaced elements with annotations and pictures. This building documentation was used for the whole duration of the renovation job.

2 An all-out opening replacement:
The old entrance door and the windows of the living room were meticulously documented (opening direction, frame thickness, etc.) so it was easy to choose the fitting replacement from the manufacturer.

3. Internal wall renovation:
Firstly, we removed the wallpaper in the living room and the hall, as requested by the customer. As the program previously calculated all wall areas with and without openings for each and every room, we used these surface values to determine how much plaster and paint we will need for the work.

4. New floor covering:
The more than 30 years old PVC floor of the hall and the wall to wall carpet of the living room were removed. As we knew the two rooms surface areas from the building model, we just added the recommended 10% extra, and that gave us exactly how much floor leveling material, insulation and laminate flooring we’ll need. This granted that we will have just the right amount materials to work with, and this also reduced waste.

5. Replacing the bathroom and toilet covering:
We simply pulled up the PDF roombook and found the needed wall and floor surface areas. With these numbers we set off to purchase the needed covering material, and tiles. Obviously, we calculated with the industry recommended “extra” so this saved us from an additional visit to the shop.


6. Installing the new sanitary equipment:
We had previously documented the replacement models’ dimensions and most important features. We just had to pick them up from the retailer.


7. Replacing the electrical equipment pieces:
The building documentation had all the annotations and comments we made on the problematic wiring, switches and outlets. We knew exactly which needed to be changed and – after showing the documentation and consulting with the client – we knew the steps we had to take.
