Turnpike Interchange Topography & Quantity - Case Study |
|
ScanWorks was commissioned by the engineer of record to provide a quality assurance as-built to the general contractor. They were looking for a quick and accurate survey of the ground in its current shape, and a quantity of the fill that was available onsite. With these two critical pieces of information the contractor would be assured that he had enough dirt to finish the job and that he was on schedule.
|
This early stage of the project is notorious for budget overruns and schedule delays because of the inaccuracies inherit to working with dirt. The challenge was to do it accurately enough to instill confidence. Conventional methods would have been sloppy and time-consuming. Ultimately our deliverable to the client was the piece of mind that the project was on the right track.
