ABNA’s CADD department utilizes 3D software such as Autodesk Civil 3D and Bentley Geopak to establish a site’s design with an emphasis on underground utility management and surface storm water flow. Using 3D tools a site’s existing and proposed utilities can be mapped in 3D to ensure that no conflict will exist on-site. These same tools are used to create detailed surface models that assist in accurate predictions of cut and fill quantities, stormwater runoff calculations and visualization of a final site. The CADD department also uses 3D rendering software such as Google Sketchup and 3D Studio Max to create presentation materials for proposals, client presentations and for use during design charettes.
