Residential structural warranties offer builders protection if unexpected defects affect a home\u2019s load-bearing elements.\r\n\r\nAs a provider of 10-year structural warranties for residential home builders, 2-10 Home Buyers Warranty (2-10) provides warranties for one in every five homes built in the conterminous United States.\r\n\r\nWhen a homeowner submits a claim under the home\u2019s structural warranty, the evaluation process begins with an on-site inspection by a structural engineer. The engineer looks for evidence of a shifting foundation\u2014such as sagging floors or cracks in drywall\u2014and surveys the elevation at key points. This determines how much the foundation has moved from its original state\u2014or \u201ctilt and deflection,\u201d in civil engineering terminology. Although the foundation\u2019s original condition is not usually documented, engineers typically assume that the foundation was built within 0.75 inches (about 1.9 centimeters) above or below levelness\/flatness.\r\n\r\nThe engineer then enters the measurements into tilt and deflection analysis software and generates a report for the claims adjuster who manages the structural claim. If the tilt and deflection measurements meet the American Society of Civil Engineers and Post-Tensioning Institute\u2019s standards for excessive foundation movement in a home, the structural claim is approved.\r\n\r\nIn 2018, 2-10 was using a third-party engineering firm\u2019s software for its tilt and deflection analysis, but the firm was ceasing operations. The software was antiquated, requiring multiple programs to complete the evaluation process. The firm offered to sell its proprietary software, but when 2-10 staff realized they could build a state-of-the-art software program for a quarter of the cost, they decided to bring the tilt and deflection analysis process in-house. To build its in-house software, 2-10 selected Esri partner Argis Solutions.\r\n\r\n<strong>Cheaper, Faster, More Accurate, and Less Labor-Intensive<\/strong>\r\n\r\nFrom 2018 through late 2019, Argis worked to create an ArcGIS Pro extension containing a customizable tool that takes accurate measurements of a home\u2019s elevation and creates a small-scale elevation model of the foundation.\r\n\r\nWith the home survey measurements, 2-10 engineers use the tool to draw lines across the elevation model. These lines help engineers determine the most significant foundation deflections and tilts. The engineers then generate a custom report with easy-to-read graphs, tilt and deflection ratios, and offset calculations for deflection using the computations and imaging that the program creates."},{"acf_fc_layout":"image","image":731192,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\u201cWith this tool, I can do an analysis in half the time it took with our old process,\u201d said Sam Vialpando, risk management engineer for 2-10. \u201cWhen we are handling a yearly volume of 200\u2013400 claims, that adds up to significant time savings.\u201d The more streamlined evaluation process allows staff engineers to focus their time on other vital tasks.\r\n\r\nThe new evaluation process is more consistently accurate, too. Paul Thomas, national risk manager for 2-10\u2019s New Home division, had the company\u2019s engineers perform extensive quality assurance testing, taking past findings from their old\u00a0program\u00a0and comparing them with the new Argis-designed program to see if they matched.\r\n\r\n\u201cWe discovered our results were mostly the same,\u201d Thomas said. \u201cWhen they were different, the Argis program was more\u00a0accurate\u00a0than\u00a0the original findings.\u201d\r\n\r\n<strong>Continued Improvement with 3D Modeling<\/strong>\r\n\r\nIn 2023, 2-10 decided to take the program a step further and add 3D modeling capabilities to make tilt and deflection reports even more user-friendly for claims adjusters and claimants.\r\n\r\nArgis used ArcGIS Pro SDK for .NET to build an add-in tool for ArcGIS Pro that creates a 3D model. The tool generates an elevation image built from a CSV file containing x,y coordinates and the coordinates\u2019 elevations. Then, the user overlays the elevation image with a PNG file of the home\u2019s foundation blueprint. The tool generates a three-dimensional side view that shows exaggerated terrain relief in different colors. Red indicates the highest elevation and purple indicates the lowest. The color-coded 3D view gives nonexperts a visual reference, helping them quickly understand the severity of a home\u2019s tilt and deflection."},{"acf_fc_layout":"image","image":731202,"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"\u201cThe 3D view shows the shape of a home\u2019s floor system. It adds another dimension to support understanding versus a flat two-dimensional model,\u201d Vialpando said. \u201cClaims adjusters aren\u2019t engineers. They need to be able to interpret and explain this very nonstandard engineering task to claimants for claim resolution. We had to be able to translate a very high-level analysis into something that could be used and understood by nonexperts.\u201d"}],"references":null},"yoast_head":"<!-- This site is optimized with the
