Anyone heard of eco3dusa from Arizona?
Eco3dusa was 3d scanning company from Arizona working in my area (central NY) to provide scanning services. I ran into them a year ago. Noticed they were scanning with Leica P30 and Faro S120 or similar. They never asked for any control points or BM’s. I never saw them use an instrument or a level. So I was suspicious of how well their end product could be on a six-story / 150,000 s.f. building. Appears they no longer exist and have since changed the company name to ZELUS. They are coming back. Now the project coordinator is asking me to hand over all my survey information. I told him that is too broad a request. I have progressively provided survey as-builts and control reports as requested, and by the clients who paid for them. After 2 years of construction, nearly all of the control is either disturbed or destroyed. I told them the scanner company will need to contract with me to verify and re-establish control as needed.
This is starting to be a problem with scanner and drone company’s that do not have a licensed surveyor on staff.
