USING ALTERNATIVE RETAINING WALLS IN REBUILDING THE FREEWAY SYSTEM IN ATLANTA

The extensive use of alternative retaining walls met four objectives of the Georgia Department of Transportation. The first objective was the reduction of adverse impact of right-of-way purchase in an urban area. 2.8 million square feet of alternative retaining walls costing approximately $96.8 million reduced construction time and hence the time during which adjacent property was affected. Wall types such as earth-anchored walls and Doublewal reduced the amount of right-of-way that needed to be purchased. The second goal was the reduction of the cost of the actual wall construction. The average construction cost dropped from $60 per square foot to $20 to $35 per square foot. Preliminary engineering costs and timm were also reduced. The third goal to speed up plan preparation was also realized. The fourth goal concelrned the speed of project construction. The construction rate of 500 square feet of vertical surface area per 8-hour day per crew for construction of alternative wall types, exceeds the rate possible for conventional cost-in-place construction. The Retained Earth Wall and the Doublewal are described as is also the Georgia Stabilized Embankment (GASE) Wall.
