Luis Alfredo C.

Structural Engineer & Construction Pathology Specialist | 13+ Years |

Is your structure showing cracks, deflection, corrosion, or damage — and you need to know if it’s safe, what caused it, and how to fix it? I help clients answer exactly that, combining structural design expertise with specialized diagnostic training in construction pathology. Over 13 years I’ve delivered structural solutions across transportation and hydraulic infrastructure — pedestrian and vehicular bridges, retaining walls, water storage tanks, box culverts, and other critical civil works — in concrete, steel, masonry, and alternative materials like timber and bamboo. Where I add the most value: • Diagnosis — structural damage assessment and failure investigation, identifying root causes (not just symptoms) • Rehabilitation — cost-effective, technically sound repair and strengthening solutions for existing structures • Design & review — new structural design and independent design review, backed by leadership experience as Director of Technical Supervision on major construction projects • Research-driven approach — linear and nonlinear analysis to understand real-world structural behavior, with a strong focus on emerging and non-conventional materials Whether you need a structure assessed before a purchase or renovation, a rehabilitation plan for an aging asset, or a full structural design done right the first time, I bring both the technical depth and the field-tested judgment to get it right. Let’s talk about your project — I respond quickly and I’m happy to review your specifics before we start.
