This work was part of the Road and Motorway Directorate\u2019s new era of standardization and digitization of processes, which the original C4 regulation for processing geotechnical investment project documentation did not cover. One of the notable results of our joint effort was the design and discussion of the C4 exchange format proposed by ISAX. This exchange format is based on XML with an XSD validation schema designed to verify that the resulting format is formally correct.<br><br>Another outcome of this collaboration is the draft of a new version of the C4 technical standard, which incorporates the C4 exchange format and clearly prescribes a machine-readable structure for geotechnical contract data files\u2014such as borehole documentation and photographic records\u2014including links to descriptive information and corrections to several ambiguities that arose from the use of the previous version of the standard. \u00a0<br><br>The team included geomatics specialists from ISAX\u2014Ing. Barbora Rackov\u00e1 and Ing. Ji\u0159\u00ed Bl\u00e1bol\u2014as well as Ing. Kamil Alferi representing the Road and Motorway Directorate of the Czech Republic (\u0158SD \u010cR), Ing. Milan Majer\u010d\u00edk representing the Railway Administration, and Richard Binko representing the Czech Geological Survey. Geotechnical experts were represented by Mgr. V\u00edt Ambro\u017e, Ing. Mgr. Jan Valenta, Ph.D., Mgr. David Relich, Ph.D., and Mgr. Mari\u00e1n Bo\u0161ansk\u00fd from our partner company Geostar s.r.o.<br><br>Another significant outcome of our joint work was the draft proposal for a BIM model of geotechnical projects for the State Fund for Infrastructure Development (SFDI), prepared by Ing. Jana Gottvaldov\u00e1, Ph.D., and Ing. Edita Kun\u010darov\u00e1 on behalf of CadConsulting. The proposal includes a BIM object representing the borehole location, the groundwater table area, and 3D cylinders representing individual geological layers, as clearly shown in the prototype design illustration.<br><br>Currently, approval processes for updating the technical regulation are underway at the Road and Motorway Directorate (\u0158SD), and the Railway Administration will be initiating a project inspired by the results from the \u0158SD, which it will certainly utilize in the planning and construction of the high-speed rail line (VRT). The Czech Geological Survey has agreed to adopt the exchange format for the newly planned automated processing of mandatory outputs from geotechnical contracts into the CGS geodatabase, which will accelerate and, most importantly, digitize the current process.<\/p>\n\n\n\n<p>Jan Jir\u00e1nek, Engineer<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1013\" height=\"475\" src=\"https:\/\/tstwp.mawis.eu\/app\/uploads\/2023\/09\/upravy-vymenneho-formatu-zaborovych-elaboratu_v3_image1.png\" alt=\"\" class=\"wp-image-30609\" srcset=\"https:\/\/tstwp.mawis.eu\/app\/uploads\/2023\/09\/upravy-vymenneho-formatu-zaborovych-elaboratu_v3_image1.png 1013w, https:\/\/tstwp.mawis.eu\/app\/uploads\/2023\/09\/upravy-vymenneho-formatu-zaborovych-elaboratu_v3_image1-300x141.png 300w, https:\/\/tstwp.mawis.eu\/app\/uploads\/2023\/09\/upravy-vymenneho-formatu-zaborovych-elaboratu_v3_image1-768x360.png 768w, https:\/\/tstwp.mawis.eu\/app\/uploads\/2023\/09\/upravy-vymenneho-formatu-zaborovych-elaboratu_v3_image1-600x281.png 600w\" sizes=\"auto, (max-width: 1013px) 100vw, 1013px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Last year, we joined the team that updated the C4 regulation.\u200d<\/p>\n","protected":false},"author":33458,"featured_media":30608,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-30603","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/posts\/30603","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/users\/33458"}],"replies":[{"embeddable":true,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/comments?post=30603"}],"version-history":[{"count":3,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/posts\/30603\/revisions"}],"predecessor-version":[{"id":34791,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/posts\/30603\/revisions\/34791"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/media\/30608"}],"wp:attachment":[{"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/media?parent=30603"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/categories?post=30603"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tstwp.mawis.eu\/en\/wp-json\/wp\/v2\/tags?post=30603"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
