the shortest construction duration overall, and can provide up to a 60% cost savings over other retaining walls.
A RETAINING WALL SYSTEM COMPARISON
The study1 considered a one-hundred-foot long retaining wall with a nineteen-foot exposed wall height, used to retain dense fine sand in an area with no water table. Although not generally required for steel sheet pile installation, the study assumed the walls were built in a cut situation with available space for open excavation. In applications where the steel sheet pile can be driven directly into the soil with-out excavation, the savings in cost and construction time would be even greater than shown below . Six retaining wall types were designed based on these basic design re-quirements, then costs and time to construct the resulting designs were prepared.
Figures 1 through 6 summarize the results for each retain-ing wall system.

COST AND PERFORMANCE
Time and money – the two factors that drive most business deci-sions. You can find a retaining wall system that delivers on both fronts, and results in a strong and permanent retaining solution. A recent comparison study1 concludes that hot-rolled steel sheet piling can provide the fastest construction time as well as signifi-cant cost savings over competing wall systems.
Evaluating the various retaining wall systems for specific project requirements can be complicated and time consuming. From their decision-making matrix, the Federal Highway Administration concludes that for permanent retaining wall structures, cost and speed of construction are typically among the most important wall selection factors2 areas where steel sheet piling excels.
In addition to economy, hot-rolled steel sheet piling offers a readily-available, environmentally-friendly solution for retaining structures, providing excellent stability and ease of construction in both per-manent an temporary applications.
The following sections present the results of the study cited above, comparing six retaining wall types in a typical permanent application. Each retaining wall system was structurally designed to meet the proposed project requirements. For the resulting wall, corresponding material and construction costs, as well as time to construct, were developed based on national average cost data3. The results show that the steel sheet piling installation has

Indiana Fabricator Wins Free Audit
PROJECTS
Covering the Colts On September, 7 the Indianapolis Colts will play their first game at brand-new Lucas Oil Stadium. Designed by architect HKS, Inc., the stadium seats 63,000 (and canbC expanded to 70,000 when it hosts the Super Bowl in 2012). The playing field is 25 ft below ~eet leve~ allowing funs unobstructed views from their easily accessed seats.
At the Colts' first game in its new home-against the Chicago Bears-fans will be sitting beneath an engineering milestone. The stadium's steel roof, designed by structural engineer Walter P Moore, is the first ever to divide lengthwise into two retractable panels-160 ft long x 600 ft wide an<:l2.9 million Ib each-with each half sliding down the steep, gabled roof of the stadium into the open position. A 960-hp cable drum drive System moves the retractable roof panels up and down the sloped track in 9 to 11 minutes depending on wind conditions. (Structural steel was fabricated by AISC Member Hillsdale Fab~icatorslAlberici Constructors.)
The project also features a retractable end wall consisting of six glass panels that
