Technical Office for steel bridge rehabilitation"},"content":{"rendered":"<p><a href=\"https:\/\/cesmaingenieros.com\/\">CESMA Ingenieros<\/a> hired Modelical to develop the BIM model of a historic steel bridge located in Blanca, Murcia (Spain).<\/p>\n<p>The steel bridge, built in the 1930s, has progressively deteriorated after decades of structural load, corrosion and environmental exposure.<br \/>\nVisible deformations in several metallic elements required a detailed understanding of the bridge\u2019s actual condition before defining a consistent rehabilitation strategy.<\/p>\n<p>The objective of the project was to develop a reliable BIM model that reconstructs the bridge\u2019s original geometry and serves as a technical reference for rehabilitation works.<br \/>\nThis approach was based on reality capture of the asset\u2019s current condition and analysis of its structural deformations.<\/p>\n<p>&nbsp;<\/p>\n<h2>Modelical\u2019s Services<\/h2>\n<p>The project was delivered by a team of three civil engineers and completed within one month, covering the full workflow from scanning to the development of a validated model.<\/p>\n<p>The scope of services included:<\/p>\n<ul>\n<li><strong>Reality capture and 360\u00b0 photography<\/strong> to obtain a highly reliable point cloud and complementary visual information<\/li>\n<li><strong>Advanced structural modelling in Tekla Structures<\/strong>, starting with parametric design and progressing to manual detailing to create a precise digital model of the historic asset<\/li>\n<li><strong>Comparative analysis between point cloud and BIM model<\/strong>, to detect deformations, deviations, and ensuring model precision.<\/li>\n<li><strong>Development of a digital inventory of structural elements<\/strong>, supporting planning, budgeting, and project control<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-29213 size-full\"

Technical Challenges<\/h2>\n<ul>\n<li>Translating a deformed point cloud into a coherent theoretical structural model, avoiding the replication of existing distortions<\/li>\n<li>Reconstructing the bridge\u2019s original geometry through the analysis of scan data, 360\u00b0 imagery, and field observations applying a parametric approach<\/li>\n<li>Modelling historic riveted joints not available as standard components in Tekla Structures<\/li>\n<li>Ensuring alignment between the theoretical model and actual conditions without introducing systematic geometric errors<\/li>\n<li>Performing model-to-cloud deviation analysis in Cyclone deformed structural elements through heat map comparison.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Benefits<\/h2>\n<p>CESMA lacked a reliable basis to assess the bridge\u2019s ageing conditions and prioritise rehabilitation interventions.<\/p>\n<p>Modelical delivered a complete and validated structural model of the bridge, including all main components, providing CESMA with a reliable digital reference for rehabilitation planning.<\/p>\n<p>Parametric reconstruction of the bridge combined with model-to-cloud comparison enabled the identification of structural deformations through heat maps, making this information available for supporting the prioritisation of actions.<\/p>\n<p>&nbsp;<\/p>\n<h2>Combining Digital Technologies and Engineering Expertise for ageing Steel Bridge BIM Modelling<\/h2>\n<p>Historic steel bridges and steel infrastructure present significant rehabilitation challenges due to material ageing, structural deformation, and non-standard construction techniques.<\/p>\n<p>To support delivery teams, Modelical has developed a comprehensive workflow integrating point cloud processing, parametric modelling, and deformation analysis.<br \/>\nThis approach enables the generation of complete, reconstructed, and validated BIM models of steel infrastructure for rehabilitation projects.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":29183,"template":"","categories":[7],"tags":[],"class_list":["post-29176","project","type-project","status-publish","has-post-thumbnail","hentry","category-works"],"acf":[],"yoast_head":"<!--
