<p><p><h2>Commentary</h2>Payment for Expanded PolyStyrene (EPS) geofoam typically consists of a pay item measured by the cubic yard (CY). Included in this bid item are associated incidental costs such as:<br><ul> <li>Material, equipment, and labor costs</li> <li>Instrumentation, monitoring, and quality control</li></ul>No specialized equipment is necessary for the construction of EPS geofoam fills, therefore additional mobilization costs are negligible.<br><h2>Cost Information Summary</h2>The following table lists items which are associated with the cost of EPS geofoam and approximate cost ranges. Cost ranges are based on data from 2008 through 2010. Readers should carefully examine the project characteristics and constraints and determine to what degree if any these factors may influence the actual cost associated with EPS geofoam fill.</p><p><table class='tablepress' id='tablepress-103'><thead><th>Pay Item Description</th><th>Quantity</th><th>Unit</th><th>Low Unit Price</th><th>High Unit Price</th><th>Factors Which May Potentially Impact Costs</th></thead><tbody><tr><td >EPS Geofoam</td><td >Greater than
