Surveying, which is often the first course of action before a project begins, establishes land boundaries, right-of-ways, and topography. ASN utilizes the latest survey tools and equipment, including GPS and both robotic and conventional total stations, to provide accuracy in survey measurement and to ensure that your projects are compatible with the boundaries and opographical conditions of the area. AVN’s surveying services are also supported by in-house GIS technicians and mappers. Our surveying and mapping teams work with a diverse group of clients, including oil and gas companies, private developers, municipalities, and state agencies. AVN’s project delivery team can facilitate and manage your entire project, eliminating multiple points of contact that delay your time to market.
