Carlos Agrazal<\/strong>, structural civil engineer, specialist in structural design and steel &amp; rebar detailing, and CEO of Grupo ADIPSA. His starting point is a direct question: is it possible to reduce the structural costs of a project in Panama without compromising safety, while also lowering its carbon footprint?<\/p>\n<p>You can also read the <a title=\"version published in the December 2025 issue of Construcci\u00f3n en Panam\u00e1 magazine\" href=\"https:\/\/cp.aflip.in\/construccionenpanama-dic25.html#page\/8\" target=\"_blank\" rel=\"noopener\">version published in the December 2025 issue of Construcci\u00f3n en Panam\u00e1 magazine<\/a> (in Spanish).<\/p>\n<h2>What is performance-based design?<\/h2>\n<p>For decades, structural design in Panama has followed prescriptive methods. They guarantee safety, but often lead to excessive use of materials and unnecessarily robust structures.<\/p>\n<p>Performance-based design changes the question. Rather than only checking that a structure meets a set of formulas and coefficients, it models more realistically how it will respond to an earthquake or an extreme load. With that information, the engineer can anticipate failures, optimize construction details and deliver more resilient projects.<\/p>\n<p>In practice, PBD relies on tools such as:<\/p>\n<ul>\n<li>Advanced nonlinear analysis.<\/li>\n<li>Simulations with historical earthquake records (time-history analysis).<\/li>\n<li>Evaluation of actual interstory drifts.<\/li>\n<li>Identification of the structure&#8217;s failure modes.<\/li>\n<li>Review of behavior under extreme scenarios.<\/li>\n<\/ul>\n<h2>What are its benefits over prescriptive design?<\/h2>\n<p>For developers, architects and investors, Eng. Agrazal sums up the advantages on three fronts:<\/p>\n<h3>Less material, lower cost and a smaller carbon footprint<\/h3>\n<p>Structural optimization avoids the oversizing typical of traditional methods. That means less steel and concrete, lower construction costs, less transport and fuel use, and a direct contribution to Sustainable Development Goals 9 (industry, innovation and infrastructure), 11 (sustainable cities) and 13 (climate action).<\/p>\n<h3>Greater safety with proven performance<\/h3>\n<p>By simulating the real behavior of the structure, PBD shows how and where it would fail instead of assuming it. That information supports design decisions with greater technical certainty, which is especially relevant in a seismically active country like Panama.<\/p>\n<h3>More competitive high-value projects<\/h3>\n<p>A safer, more efficient and optimized building has a higher market value, reduces risk and improves return on investment.<\/p>\n<h2>Is performance-based design legal in Panama?<\/h2>\n<p>Yes. According to Eng. Agrazal, the regulatory basis already exists:<\/p>\n<ul>\n<li><strong>REP-2014:<\/strong> formally introduced the concept of performance-based design into the Panamanian Structural Code (Reglamento Estructural Paname\u00f1o).<\/li>\n<li><strong>REP-2021:<\/strong> regulated its use, so its implementation became legally authorized.<\/li>\n<\/ul>\n<p>PBD does not replace REP-2021; it complements and strengthens it. It must start from the minimum loads, seismic parameters and criteria of the Panamanian code, but it allows optimizations to be justified through advanced analyses consistent with international best practice.<\/p>\n<p>The Technical Board of Engineering and Architecture (JTIA) and the municipal building departments recognize its value, as long as the design is properly documented, modeled and justified.<\/p>\n<h2>Why is it now viable for real projects?<\/h2>\n<p>Until a few years ago, applying PBD to a real project required computing power that was hard to obtain within reasonable timeframes. Today that obstacle has practically disappeared thanks to:<\/p>\n<ul>\n<li>Multicore processors and graphics cards optimized for computation.<\/li>\n<li>High-speed NVMe storage.<\/li>\n<li>Mature software such as ETABS, SAP2000, MIDAS, Perform 3D and OpenSees.<\/li>\n<li>Integration between BIM and structural analysis.<\/li>\n<\/ul>\n<p>With these tools, simulations that used to be possible only in laboratories or research centers can now be run in Panama. A methodology that seemed reserved for megacities or large international government projects becomes accessible to the local market.<\/p>\n<h2>What does it demand from the structural engineer?<\/h2>\n<p>PBD is neither quick nor simple. It requires a higher professional level:<\/p>\n<ul>\n<li>Advanced training in structural dynamics.<\/li>\n<li>Command of nonlinear analysis.<\/li>\n<li>Solid knowledge of the Panamanian Structural Code (REP).<\/li>\n<li>Experience in performance modeling.<\/li>\n<li>The ability to document assumptions and results.<\/li>\n<li>Specialized software and hardware.<\/li>\n<\/ul>\n<p>In return, it raises Panamanian engineering to international standards: those who master the methodology can offer projects with lower cost, greater efficiency and better seismic performance.<\/p>\n<h2>Which projects in Panama benefit most?<\/h2>\n<p>The country is expanding vertically and in critical infrastructure. According to Eng. Agrazal, the sectors that can benefit most are:<\/p>\n<ul>\n<li>Towers in Costa del Este, Santa Mar\u00eda and the Cinta Costera.<\/li>\n<li>Logistics corridors.<\/li>\n<li>Bridges and road works.<\/li>\n<li>Data centers and hospitals.<\/li>\n<\/ul>\n<p>These projects call for smarter, safer and more efficient structures.

However, it requires more hours of specialized analysis, so its advantage is greatest in tall buildings, critical infrastructure and high-value projects.<\/p>\n<h2>The present, not the future<\/h2>\n<p>After applying it on real projects, Eng. Agrazal argues that performance-based design is not a future trend but the methodology of the present, with proven benefits in performance, efficiency and sustainability.<\/p>\n<p>In an environment that demands environmental responsibility, resource optimization and structural resilience, PBD becomes a strategic tool for those who want to design and build in Panama with a long-term vision: safer, more efficient, more economical, more sustainable and more competitive structures.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Eng.
