1. A grading contractor has a grading plan provided to them by a firm that doesn't use 3d modeling.
2. Said grading contractor asks my company to provide a 3D terrain model that they can use in their GPS controlled equipment.
What I am looking for is a way to create some quality control to the final product. How do we check the model to ensure that what we are providing to the contractor is an accurate representation of the other firms grading plan? What liabilities are acceptable? Has any other company out there had any experience or success with this?
