Department of Veterans Affairs

Sioux Falls, South Dakota

Ehrhart Griffin and Associates teamed with Prochaska and Associates to prepare construction documents for a new addition to the Hospital for the Department of Veteran Affairs in Sioux Falls, South Dakota. EGA was retained to perform engineering analysis and final plans for demolition and reconstructive services for the addition. Design considerations included pavement replacement and reconfiguration of the main handicap accessible entrance, sanitary sewer improvements, storm sewer modifications and fuel tank removal and replacement.

Ehrhart Griffin and Associates design responsibilities included preparing a Removal Plan, Site Layout Plan, Utility Plan, and Grading Plan for the new addition. Design goals for demolition, site and utility layout included minimizing material removal and replacement and utilizing any existing features to reduce project costs.

EGA developed options to minimize removals of trees and pavement to accommodate the new sanitary sewer. The sanitary sewer improvements included the design and installation of new metering equipment to monitor the sanitary flow that will now enter the system belonging to the City of Sioux Falls.

Ehrhart Griffin & Associates conducted a topographical survey using state-of-the-art electronic surveying equipment. Construction documents were prepared using the latest computer aided design software and systems.

Hegg Memorial Health Sytem Campus

Rock Valley, Iowa

Ambulance Addition and Parking Lots:

Ehrhart Griffin & Associates Sioux Falls was retained to perform a full boundary and topographic survey for the 12 acre Hegg Memorial Health System campus. In addition to surveying services EGA was retained to provide civil engineering services for three separate campus improvements, including an ambulance addition, parking lot improvements and a building addition to the east clinic entrance.

The absence of underground storm sewer and the existing flat topography was a major design challenge and was met with several unique design solutions. These solutions included use of cast iron pipe and routed surface flows.

All surveys and construction drawings were collected and prepared with state-of-the-art electronic surveying and computer aided drafting and design (CADD) equipment systems.
