2018: CNC Surveying Begins

Construction Surveying Omaha

CNC Surveying is owned and operated by Carmel and Tim Conway with Vance Clark as non-owner board member. We are staffed by people who Vance and Tim have worked with over their combined 90 years with major engineering companies in Omaha. We do all aspects of professional land surveying projects.

Quality work done effectively leads to satisfied repeat clients.

In 2018, CNC Surveying, LLC began offering construction surveying services to general contractors in the Omaha area. While all types of surveying present challenges, construction staking carries the greatest risk due to the high consequences of errors. Fortunately, Tim brought decades of experience in construction surveying to the table, making him well-equipped to handle these risk demands.

Accuracy is critical in construction surveying. Mistakes can be costly, which is why CNC emphasizes a core surveying principle: independently verify your work—and do so early in the project. This philosophy has guided CNC from the beginning. Tim founded the company on the belief that if you set things up correctly from the start and maintain that standard, success will follow. CNC rarely makes mistakes, thanks to this disciplined and proactive approach.

The primary control used to lay out work for contractors functions like a frame before a picture is placed inside it. For example, when we begin staking a building, we first “station” the architectural and structural plan sheets. We assign the origin point—station 0,0—to the lower-left corner of the building footprint. From there, we mark each angle point on the architectural sheet and each column location on the structural sheet.

To ensure accuracy, we “check in” by approaching the same station point from the opposite direction on the plan. In the field, our offset stakes align precisely with the building envelope—a square or a rectangle. The measured distances in the field must match the values calculated in the office, and the diagonal measurements of the envelope must confirm the office calculation.

This rigorous process allows us to confidently say to our clients:
