Scale constraints from total station separating tie points into 2 sets

Double grid of scene (long curve). Tie points come in fine with no apparent problems.

Scaling the project with scale constraints measured via total station. Roadway width is already fairly accurate to start, like usual. However, roadway length is off by a factor of nearly x2 (unusual). Scale constraints to proper measurements shifts approx half the tie points to a different plane entirely. Total station measurements verified with Google Earth measurement tool.

What’s the fix?

Would you please upload the quality report and explain it in more detail about the “scale constraints” (ex, how many, what is the direction and length)? It would be helpful to investigate.
