DRG's Engineering Department is excited to announce the purchase of Bentley's AutoPlant Piping® and Data Management® software. This is intelligent 3D software with interactive data management allowing us to better meet your needs for Bill of Materials, Procurement, and As Built documentation for DOT compliance demonstration. It also allows us to provide you with 3D models of the fabrication assemblies used in your pipeline.
DRG uses Microsoft Project® software to manage our jobs. This allows us to centrally control scheduling and cost considerations and provides an efficient method for organizing and communicating project data.
