Authored by Erika Acton, P.Eng. of Isherwood Geostructural Engineers, the document traces the evolution of micropile technology from its inception as 'Pali Radice' or 'Root Piles' by Fernando Lizzi in Italy during the 1950s, through its introduction to North America in 1971, and its eventual adoption and implementation in Toronto projects starting around 2002. The content serves as a professional record of structural engineering practices, highlighting project experiences and the maturation of deep foundation techniques within urban construction environments. The materials illustrate the necessity and integration of these support systems in historical monument preservation, such as the church of Tourny, while documenting the technical testing and implementation procedures used by Isherwood Geostructural Engineers in modern projects.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/a-historical-overview-of-the-innovative-use-of-micropiles-acton/664594/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/a-historical-overview-of-the-innovative-use-of-micropiles-acton/664594.png","ImageObject",300,407,{"name":92,"@type":93},"Angel","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Who invented the micropile and what was its original name?","Question",{"text":112,"@type":113},"Micropiles were invented in Italy by Fernando Lizzi, who originally referred to them as 'Pali Radice' or 'Root Piles.'","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"When were micropiles first used in Toronto?",{"text":117,"@type":113},"According to the document's timeline, micropiles were first used in Toronto in 2002.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the primary focus of Isherwood Geostructural Engineers' experience mentioned in the document?",{"text":121,"@type":113},"The firm focuses on the innovative use of micropiles for the support of excavation and the stabilization of façades in Toronto, Canada.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},664594,1793261302,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":24,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":26,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":143},687207412472,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","Isherwood Geostructural Engineers  \nPresenter: Erika Acton, P.Eng.  \nA Historic Overview of the Innovative Use of Micropiles for Support of Excavation and  \nFaçades in Toronto, Canada  \n15th ISM International Workshop on Micropiles  \nIsherwood Micropile Project Experience  \nCANADA / ONTARIO / GTA / TORONTO  \nHistory of Micropiles in Toronto  \nTimeline  \n1950 (Italy) 1971 (North America) 2002?
