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.

The New I-64 Design/Build MSD CSO Interceptor & Outfall Modifications

The New I-64 Design/Build

Owner: Missouri Department of Transportation
Client: Parsons

This fast paced Project included a complete reconstruction of I-64/Hwy40  and its associated appurtenances. This $535 million Capital Project is located over a 12 mile stretch of Missouri’s Interstate.  ABNA provided engineering design including structural, drainage and utility designs.  The structural design included the I-170 flyways, several bridges and a pedestrian tunnel ; drainage design entailed accommodating flow for the new pavement including several retention ponds; and utility design entailed relocations for more than 20 individual utilities within the corridor such as for fiber, cable, sewer, water, electric and gas.  In addition, ABNA provided inspectors and field technicians during the infrastructure’s construction.

 

MSD CSO Interceptor & Outfall Modifications

Owner: Metropolitan St. Louis Sewer District

ABNA was responsible for seven (7) sewer outfall structures supported on steel piles and provided steel sheet piling for erosion protection along the Mississippi River from south St. Louis to the Merchant’s RR Bridge. The CSO’s are being designed in accordance with the Overflow Regulation System (ORS) and the interceptors inspected to help provide alternatives & recommendations to MSD. All efforts were coordinated with the COE – St. Louis District.
