The structure is approximately 57,600 square‐foot building with associated roadway, pavement & parking areas. Due to the presence of loose to medium‐dense fine sands to slightly clayey fine sands in the upper 25 feet, the Geotechnical Engineer of Record recommended a ground improvement program for Vibro‐Replacement Stone Columns (VSC). In addition, because of the presence of overburden soil erosion/raveling evidence related to possible “sinkhole conditions”, the Geotechnical EOR recommended a Compaction Grouting (CG) program to mitigate the concerns.\n\n[/cs_content_seo][/cs_element_layout_column][/cs_element_layout_row][/cs_element_section][cs_element_section _id=”29″ ][cs_element_layout_row _id=”30″ ][cs_element_layout_column _id=”31″ ][cs_element_text _id=”32″ ][cs_content_seo]Challenge\n\n[/cs_content_seo][cs_element_text _id=”33″ ][cs_content_seo]The challenges encountered during VSC installation were minimal:• Limited movement around the site, due to ongoing site conditions• Weather conditions were unfavorable and slowed production\n\n[/cs_content_seo][/cs_element_layout_column][/cs_element_layout_row][/cs_element_section][cs_element_section _id=”34″ ][cs_element_layout_row _id=”35″ ][cs_element_layout_column _id=”36″ ][cs_element_text _id=”37″ ][cs_content_seo]Solution\n\n[/cs_content_seo][cs_element_text _id=”38″ ][cs_content_seo]Helicon followed the Compaction Grout (CG) parameters, provided by the Geotechnical Engineer of Record, during the installation. Our crew installed (21) grout injection points to approximately 30‐50 feet. Helicon also worked alongside the general contractor & the geotechnical/structural design teams, to develop a cost‐conscious Vibro‐Replacement design submittal. The VSC Program was designed to meet the design load criteria of 6,000 psf allowable. Helicon’s VSC crew worked approx. 10‐hour shifts for up to six days a week, in order to meet the client’s critical path schedule. Efficient planning & coordination was key to overcoming the challenges & limitations. (394) Vibro‐Replacement Stone Columns (VSC) were installed from site grade to depths ranging from 10‐ft to 25‐ft. Helicon collaborated with the Geotechnical Engineer of Record throughout the work and confirmed all recommended criteria werefollowed. The CG & VSC work was successfully completed in just (12) days and finished on‐time and within budget.\n\n[/cs_content_seo][/cs_element_layout_column][/cs_element_layout_row][/cs_element_section][cs_element_section _id=”39″ ][cs_element_row _id=”40″ ][cs_element_column _id=”41″ ][cs_element_image _id=”42″ ][cs_element_image _id=”43″ ][cs_element_gap _id=”44″ ][/cs_element_column][cs_element_column _id=”45″ ][cs_element_image _id=”46″ ][cs_element_image _id=”47″ ][/cs_element_column][/cs_element_row][/cs_element_section][/cs_content]
