Juan Caro<\/strong>, civil engineer specializing in highway engineering and manager of SECONPA S.A., and his team&#8217;s experience surveying for infrastructure megaprojects in the country.<\/p>\n<p>You can also read the <a title=\"version published in the February 2026 issue of Construcci\u00f3n en Panam\u00e1 magazine\" href=\"https:\/\/cp.aflip.in\/construccionenpanama-feb26.html#page\/8\" target=\"_blank\" rel=\"noopener\">version published in the February 2026 issue of Construcci\u00f3n en Panam\u00e1 magazine<\/a> (in Spanish).<\/p>\n<h2>Why does Panama&#8217;s terrain call for LiDAR?<\/h2>\n<p>\u201cPanama is not a simple territory,\u201d Caro warns: steep slopes, variable soils, flood zones, dense vegetation and urban expansion moving faster than planning. For years, design relied on limited surveys and technical assumptions that are now insufficient for the scale of today&#8217;s projects.<\/p>\n<p>The biggest obstacle in the tropics is vegetation cover. With conventional surveying, knowing the \u201cbare earth\u201d beneath the forest means cutting trails with machetes: a slow, costly process that is risky for staff and has a high environmental impact.<\/p>\n<h2>How does LiDAR work under vegetation?<\/h2>\n<p>A sensor mounted on an industrial-grade drone emits millions of laser pulses per second and records multiple returns. Some of those pulses filter through leaves and branches and reach the ground. Classifying those points produces a Digital Terrain Model (DTM) with centimeter-level accuracy. To learn about the deliverables in detail, see our guide to <a title=\"point clouds, DTM and contour lines\" href=\"https:\/\/constructhubs.com\/en\/point-cloud-dtm-contour-lines\/\">point clouds, DTMs and contour lines<\/a>.<\/p>\n<h2>From measuring points to understanding the terrain<\/h2>\n<p>For Caro, LiDAR is not just a tool for collecting data, but for building a three-dimensional representation of the territory before intervening in it. \u201cThat difference, between measuring isolated points and understanding the terrain as a system, is what transforms decision-making.\u201d It makes it possible to:<\/p>\n<ul>\n<li>Model real slopes and analyze drainage basins.<\/li>\n<li>Calculate cut and fill volumes more accurately.<\/li>\n<li>Detect conditions that could affect the stability of the works.<\/li>\n<li>Simulate and compare alternatives before committing resources.<\/li>\n<\/ul>\n<p>An underestimated slope, a poorly projected runoff or a miscalculated volume affect not only the engineering but also financial viability. \u201cEfficiency is not always about building faster, but about correcting less.\u201d<\/p>\n<h2>Applications in Panama&#8217;s megaprojects<\/h2>\n<h3>Linear projects: roads, railways and bridges<\/h3>\n<p>They benefit the most. A railway requires very strict curve radii and grades, and drone LiDAR can scan long corridors in a matter of days. For bridges and viaducts it complements geotechnical studies by showing riverbed morphology and flood zones. Works such as the Panama\u2013David train, the Fourth Bridge over the Canal or urban cable car systems are examples of the type of project that benefits.<\/p>\n<h3>Public-private partnerships<\/h3>\n<p>For a <a title=\"PPPs in Panama\" href=\"https:\/\/constructhubs.com\/en\/public-private-partnerships-panama\/\">PPP in Panama<\/a> to be bankable, its feasibility studies must rest on solid data. High-density point clouds make it possible to design more efficient alignments and identify hidden water bodies and critical slopes before moving the first stone.<\/p>\n<h3>BIM and clash detection<\/h3>\n<p>Imported into Civil 3D, Revit or Navisworks, the point cloud creates a real-context environment for design. In dense urban areas, it makes it possible to detect clashes between the new structure and existing buildings, power lines or surrounding topography, and resolve them in design rather than on site.<\/p>\n<h3>Staff safety<\/h3>\n<p>Aerial surveying avoids sending crews to the edges of high-traffic roads, cliffs or hard-to-reach areas, improving occupational safety indicators.<\/p>\n<h2>Does LiDAR replace traditional surveying?<\/h2>\n<p>No. Traditional methods remain useful for control and point staking. \u201cLiDAR does not replace the engineer or the surveyor. It enhances their analytical capacity,\u201d says Caro. Combining field experience with digital modeling is what allows decisions with less margin for error.

Thanks to multiple returns, some pulses reach the ground and make it possible to generate a terrain model beneath the vegetation.<\/p>\n<h3>How accurate is it?<\/h3>\n<p>A Digital Terrain Model obtained with drone LiDAR achieves centimeter-level accuracy, depending on the equipment and control methodology.<\/p>\n<h3>At what stage should it be used?<\/h3>\n<p>From pre-investment and conceptual design, when reducing uncertainty avoids later redesigns and cost overruns.<\/p>\n<h2>First, build knowledge of the territory<\/h2>\n<p>\u201cThe question is no longer whether LiDAR works,\u201d Caro concludes. \u201cThe relevant question is whether Panama&#8217;s construction industry is willing to systematically adopt tools that reduce uncertainty.\u201d In a country betting on megaprojects, understanding the terrain precisely stops being a competitive advantage and becomes a basic necessity.<\/p>\n<p>You can also read the article <a title=\"LiDAR surveying in Panama for megaprojects\" href=\"https:\/\/cp.aflip.in\/construccionenpanama-abr26.html#page\/12\" target=\"_blank\" rel=\"noopener\">LiDAR Surveying in Panama: Key for Megaprojects<\/a> in the April 2026 issue (in Spanish).
