The steel tiebacks had been used to brace shoring from two mid-rise development excavations.<\/p>\n<p>The report said the integrity of the roadway, nearby subway tunnel and surrounding infrastructure was undermined as a result of ground movement around the boring machine due to excessive ground water and poor soil conditions. The ground instability further led to the creation of a sinkhole in the work zone.<\/p>\n<p>Clearway would review the impacted area and proceed with machine rescue operations, including de-stressing and removing the steel tiebacks and undertaking jet and compaction grouting to stabilize the ground.<\/p>\n<p>The budget for the operation would include improvement of ground conditions using phase compaction grouting.<\/p>\n<p>The work was being undertaken as part of the City of Toronto\u2019s Basement Flooding Protection Program.<\/p>\n<p>WSP Canada has been advising the city on the rescue project.<\/p>\n<p><strong>Watch the DCN for updates.<\/strong><\/p>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-5143531171910809\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<!-- News - Bottom -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-client=\"ca-pub-5143531171910809\"\r\n     data-ad-slot=\"8320848692\"\r\n     data-ad-format=\"auto\"\r\n     data-full-width-responsive=\"true\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><a href=\"https:\/\/canada.constructconnect.com\/dcn\/news\/projects\/2023\/03\/toronto-moves-to-rescue-ensnared-boring-machine\" rel=\"nofollow noopener\" target=\"_blank\">This article was originally posted at Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>TORONTO\u2014The City of Toronto is planning to hire Clearway Construction Limited to extricate a micro- tunnelling boring machine that has &#8230; <a title=\"Toronto moves to rescue ensnared boring machine\" class=\"read-more\" href=\"https:\/\/essential.construction\/news\/toronto-moves-to-rescue-ensnared-boring-machine\/\" aria-label=\"Read more about Toronto moves to rescue ensnared boring machine\">Read more<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1037],"tags":[357,295],"class_list":["post-13832","post","type-post","status-publish","format-standard","hentry","category-daily-commercial-news","tag-blog","tag-technology","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-33"],"_links":{"self":[{"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/posts\/13832","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/comments?post=13832"}],"version-history":[{"count":0,"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/posts\/13832\/revisions"}],"wp:attachment":[{"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/media?parent=13832"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/categories?post=13832"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/essential.construction\/news\/wp-json\/wp\/v2\/tags?post=13832"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
