About 4DSC

4th Dimension Surveying & Consulting began when two land surveyors imagined a better way to accomplish their jobs using the latest drones and survey technology.

These technologies and our years of expertise with them allow us to offer an incredible array of services that are now available to benefit all of our clients from various industries.

Thomas and his crew did excellent work for my consulting firm in a professional, timely, and cost effective manner. I look forward to working with them again on my next North Dakota project!

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 !
