Any building that is constructed should last for a long time unless they are built for temporary purposes. A vast majority of the structures that we see today were constructed years back from our time. Therefore, structural auditing is an essential factor in deciding the strength of the building. This blog will highlight the phases of structural auditing and its necessity.
Jacob Engineers is one of the top structural engineering companies in Chennai due to its in-depth structural auditing methodology that promises precision. We never overlook even the smallest component in a design.
So, before diving deep into structural auditing, here is a short prelude to what structural auditing is and why it matters.
What is structural audit?
Structural auditing concerns the total health of the building. Regular auditing of the structure will bring to light deficiencies in a section of the building. From there on, the engineers can suggest repair, renovation, or a complete revamp.
Therefore, nothing is left to chance, and even the slightest problem is swiftly addressed.
Time frame for structural auditing
Since structural auditing is mandated by the Government, every project must undergo this process. Those buildings that are fifteen to thirty years old should be audited every five years. For buildings that are more than thirty years old, a structural audit should be done every three years.
Our team of structural engineers in Chennai comply with all the norms to ensure the integrity of all the projects we work on.
Phases of Structural auditing
1 – Visual Inspection
The engineers will perform a walkthrough to identify any issues that are easily visible on sight. Structural deformation or material debasement is addressed in this phase, either with reinforcements or replacements.
Every component like columns, slabs, beams, roofs, false ceilings, and railings is scrutinized. The investigation may also extend to other sections of the building.
2 – Non-destructive Testing (NDT)
Next to visual inspection, the engineers perform non-destructive testing to assess the structural integrity of the concrete. NDT evaluates parameters like concrete strength, Concrete Strength, Rebar location, crack propagation, and Rate of Corrosion. These tests are being conducted to gauge the reliability of the concrete:
- Seismic diagnosis & fire resistance test
- Rebound Hammer Test – Rapid estimation of compressive strength of concrete.
- Chemical tests to find pH value, carbonation, and sulfate contents
- Half-cell potential test to assess corrosion
3 – Analysis Report
In the final phase, the consultants consolidate their findings and recommendation as a detailed structural auditing report. The report will highlight the following:
- Sections in need of repairs due to breakage or deterioration
- Recommendations to increase the load-bearing capacity and supersize the existing components to make it more stable.
- Restoration and retrofitting suggestions to improve the performance of weaker structural components.
- Suggestions to increase the load-bearing capacity wherever required and improve the existing components to make it more stable.
Jacob Engineers have earned the reputation of being one of the reputed structural retrofit consultantsbecause of our consistent track record of providing detailed structural audit reports to strengthen the building and ensure its longevity.
