Surveying Liability: Managing Coordinate Risk
In construction, a coordinate error is not just a math problem—it's a lawsuit. Understand your legal 'Duty of Care'.
How to Use
Review the liability checkpoints below and integrate them into your project specifications.
Online Tool
Use Cases
- Drafting scope of work for surveying subcontractors.
- Legal defense preparation for boundary disputes.
When Professional Consultation Is Recommended
For scenarios where self-check tools cannot mitigate risk, certified professional consultation is mandatory:
- Potential for multi-million dollar damages due to geodetic misalignment.
- Professional Indemnity (PI) insurance claims involving technical coordinate errors.
- Development of safety-critical navigation systems for autonomous vehicles or aircraft.
See the Decision Boundary Guide for detailed risk thresholds.
FAQ
Q: Can I be sued for using the wrong datum?
A: Yes. If standard of care requires WGS84 and you use a legacy datum without documentation, it constitutes negligence.
Q: What is 'Duty of Care' in surveying?
A: The legal obligation to adhere to standards that a reasonable professional would use in similar circumstances.
Q: Can contracts override geodetic science?
A: Physics wins on the ground, but contracts win in court. Ensure they match.
