Chennai's tropical climate, coastal humidity, monsoon flooding, and aggressive soil conditions in many localities create structural stress on buildings over time. Rebar corrosion, concrete spalling, foundation settlement, and crack propagation are all more common here than property owners realise. Buildogram coordinates engineer-led structural audits — systematic, safety-first assessments that document the structural health of your building and recommend a clear repair pathway.
How We Support You
Visual Structural Inspection
Systematic inspection of all structural elements — columns, beams, slabs, walls, and foundation zones.
Crack Pattern Mapping
Classify cracks by type (flexural, shear, settlement, shrinkage), width, and location. Pattern analysis identifies the structural cause.
Corrosion & Spalling Assessment
Check for rebar corrosion (rust staining, spalling concrete), concrete cover delamination, and leakage-related structural distress.
Settlement & Deflection Analysis
Assess differential settlement, floor deflections, door/window frame distortions, and structural movement indicators.
NDT Coordination
Coordinate Rebound Hammer (Schmidt Hammer) and Ultrasonic Pulse Velocity (UPV) testing for quantitative structural assessment where needed.
Structural Audit Report
Written report with all observations, severity classification, and repair/retrofit pathway recommendations.
Frequently Asked Questions
What is a structural audit and when do I need one?
A structural audit is an engineer-led assessment of your building's structural health. You need one if your building shows cracks, spalling, or settlement, is more than 15 years old, has been through a major flood or structural modification, or you are buying or selling an older property.
What are the warning signs that a building needs a structural audit in Chennai?
Key red flags: diagonal cracks at door/window corners, horizontal cracks in beams or columns, rust staining on concrete, floor deflections (slab distress), water seepage through structural cracks, and unusual sounds or vibrations from the structure.
What is NDT testing for buildings?
Non-Destructive Testing (NDT) techniques assess concrete quality without damaging the structure. Rebound Hammer testing measures surface hardness correlated to compressive strength. Ultrasonic Pulse Velocity (UPV) detects internal voids, cracks, and concrete quality. These are coordinated by Buildogram as add-ons to visual audit.
Which buildings in Chennai most commonly need structural audits?
Buildings most commonly needing audits in Chennai: buildings older than 15 years, buildings in Velachery and other flood-prone areas (repeated inundation causes foundation erosion), coastal zone buildings (salt-air accelerates rebar corrosion), buildings that have undergone additions or modifications without engineering oversight, and buildings showing any visible crack progression.
Does a structural audit report help for property sale?
Yes. A professional structural audit report provides documented evidence of building safety — valuable for property transactions, insurance assessments, and bank loan disbursement for older properties.
