I have  a difficult property layout, in a very old plotted land subdivision and I was very impressed with the knowledge and ability to complete the survey with extreme accuracy. I would recommend them in any situation. Their drone program is one of a kind as I incorporated that in my survey as well and was very impressed.

I’ve had the pleasure of working with 4th Dimension on a professional and personal level. Thomas and his team were able to provide us a cost effective 3D scan of a piping project that we incorporated into our as-built. The Project Manger was thrilled to have this type of data for their records. 4th Dimension uses the newest technology combined with years of field experience to provide turn keys solutions to real world problems.

Randy Neset

Contacted Tom at 4th Dimension about surveying a parcel of land. Had a quote in less than a day and the work was completed a short time later. Excellent communication and went above and beyond answering any questions I had. I would highly recommend 4th dimension surveying and consulting.


4th Dimension was so fast and efficient when doing my survey . The price was completely fair and I am beyond happy.  I will be passing on the name anytime someone I know needs a survey !
