How Structures Evolve Over Time: Importance of Ongoing Assessment

🏢 Not every building needs demolition. But every building deserves evaluation before decisions are made. The hidden life of a structure often tells us more than its façade. In my career, I’ve seen existing buildings transformed from “unsafe liabilities” into renewed assets — simply because someone took the time to evaluate them properly. Evaluation is not just about cracks in concrete or settlement under foundations. It’s a multi-disciplinary investigation that covers: 📑 Document Review – drawings, permits, previous modifications. 🏗️ Structural Assessment – load capacity, deterioration, fatigue. 🌍 Geotechnical Check – soil movement, groundwater effects, foundation health. 🧪 Material Testing – core samples, NDT, reinforcement checks. 🔌 Services & Safety – fire systems, electrical, mechanical, sustainability. Why does it matter? ✔️ Extends the building’s lifespan ✔️ Saves millions compared to rebuilding ✔️ Increases safety & compliance with codes ✔️ Unlocks retrofit and sustainability opportunities 👉 In the Middle East, thousands of buildings are reaching 20–30 years of age. The question is no longer “Can we build new?” — but “Can we make the old safe, efficient, and sustainable?” 💡 If you were a decision-maker, would you invest in evaluation and retrofit, or choose demolition and rebuild? #Engineering #Construction #BuildingSafety #Sustainability #CivilEngineering #geotechnical #Structural #saudi #2030

Understanding Structural Reliability: I was recently asked to be involved in a project converting a 1960s car park into a bar, which I respectfully declined. The proposal involved using 2.5 kPa for bar loading instead of the 5 kPa specified in AS 1170.1, with a certifying professional providing documentation accepting the reduced load based on "two people per square meter equals 2.0 kPa." I highlighted that this approach misinterprets Australian Standards by reducing the design load without understanding the safety implications. I explained that undertaking this reduction would cause the structural reliability index to decrease well below the satisfactory level for public use. This becomes even more critical when considering the structure's age. As a 50-60-year-old building, natural deterioration through material aging compounds the reliability reduction from the lower design loads. To illustrate the concern, I performed preliminary reliability calculations. The analysis revealed a substantial decrease in structural safety, especially when factoring in the deterioration effects of a 50 to 60 year old building. Australian Standards and other recognized standards specify minimum loading for good reason—these requirements reflect extensive calibration to account for dynamic loading, crowd behavior, equipment loads, and statistical variability over a structure's service life. This case illustrates why understanding the principles behind our standards matters. When engineering requirements are simplified without considering their underlying safety philosophy, we risk compromising the protection they were designed to provide.

Importance of Structural Safety in Modern Design In civil engineering, no innovation or aesthetic can outweigh the importance of safety. Every structure we design must protect lives first. ✔️ Following codes & standards ✔️ Using quality-tested materials ✔️ Designing for resilience against earthquakes, wind & climate ✔️ Monitoring and maintaining throughout the lifecycle Modern design isn’t just about building higher, faster, or cheaper — it’s about building safer. Because a safe structure is the true measure of good engineering. 🏗️ #CivilEngineering #StructuralSafety #SustainableDesign #EngineeringExcellence

In residential builds, two elements often receive less attention than they deserve: septic systems and drainage. When they are overlooked, the consequences are costly. At Lea & Braze Engineering, we’ve seen projects stall when septic placement is considered too late, or when drainage isn’t designed to handle slope and soil conditions. The solution is clear: ✔️Integrate septic and drainage design from the start. ✔️Use accurate survey data as the basis for planning. Rely on experienced engineers for long-term performance. Invisible infrastructure supports the visible success of a project. Getting it right from the beginning is essential. https://lnkd.in/gt5pdvht #leabraze #engineering #technology #design #landsurveying #septicservices

Steel, concrete, and a little creativity. Bridging two structures isn’t just about filling a gap—it’s about transferring load paths, ensuring continuity, and making sure the old and new work together seamlessly. In the photo below, you can see a new steel-framed link connecting into existing construction. These transitions are some of the most fascinating challenges in structural engineering. They force us to think about: Load transfer: How does the new framing engage the old system without overloading it? Differential movement: What happens as the two structures shrink, creep, or settle at different rates? Fireproofing & detailing: Notice how new members are already fireproofed—how do we maintain rating continuity? Construction sequencing: How do you safely build and stabilize a connector like this while the building is in use? We love seeing examples like this because they highlight that structural engineering isn’t always about designing something brand new—it’s often about integrating and adapting what’s already there. 👉 Have you tackled a project where tying into an existing building created unique challenges? We’d love to hear how you approached it. #StructuralEngineering #Construction #StructuralDesign #engineering #civil #structure
