For more than 25 years, American Surveying Consultants (ASC) in Chicago has specialized in meeting the surveying challenges of the transportation industry in the Midwest. ASC has earned a reputation as a leader in its field. A key reason for this has been the company's success in deploying new technologies to meet the needs of clients, including its latest addition-deployment of design-grade laser scanning. Once a specialized technology for structural as-builts, ASC has turned this technology into a cost-effective, everyday tool for transportation surveys.

As more transportation clients realize they can trust digital terrain models (DTMs) that include mapped topographic features surveyed using design-grade laser scanners, more surveying and engineering firms are turning to this technology. It offers more efficiency over traditional methods, is cost-effective and greatly enhances safety in the field.
