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.

Habitat for Humanity St. Louis Urban Development Design

Owner: Habitat for Humanity, St. Louis

ABNA provided field reconnaissance, survey and civil design for nearly 30 LEED Platinum certified homes with an additional 24 currently under construction. These new homes incorporate green concepts that are not yet common to St. Louis such as Geothermal Heating and Rain Gardens. The partnership of Habitat’s efforts and ABNA’s rain garden design which incorporate water purification and rain harvesting into the landscape are helping to shape policy for the local sewer district, which has authority for water conveyance for two counties in the region. These homes have provided a dramatic transformation of a community that was overrun with vacant properties and has also provided an opportunity to educate new homeowners on their environmental footprint and the importance of living environmentally conscience

University of MO-Columbia Surgery Tower

Owner: University of Missouri Hospital Center
Client: HOK

ABNA oversaw preliminary design for site layout, loading ducts and building connection pathways. Additionally ABNA analyzed impact of utilities on the project and owner confirmed prospect of relocating existing utilities under building foot print. Another project consideration was the utilization of disconnected utilities after parking garage is demolished. 




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.
