Structural Audit and Analysis
A structural audit is a comprehensive check of building safety by analyzing and suggesting appropriate repairs and retrofitting measures required for the building to perform better in its service life.
Over time, there are many reasons that can weaken the structures, and the most common of them are structural deficiency, material deterioration, unexpected overloads, and physical damage due to accidents. A structural audit is an effective way of identifying defects and assessing the current condition of the structure. The general advice is to conduct structural audits every 5 years and every 3 years for structures older than 30 years. This includes not only building structures (such as public, commercial, residential, and industrial buildings), but also non-building structures (such as bridges, jettys, silo tanks, and retaining walls).
Our structural audit typically covers:
- Forensic or damage analysis through a visual check for any structural defects, damages, distress, deformation, and/or deterioration
- Plan and alignment between the as-built drawing and the existing condition
- Load conditions floor-to-floor
- Seismic evaluation
- Evaluation of the structure per current code requirements and/or at the time of construction
- Finite Element Analysis (FEA)
- Failure analysis
- Non-destructive testing, as needed (ultrasonic pulse velocity tests, hammer tests, rebar scanning tests, steel thickness measurements, corrosion measurements)
- Destructive testing, as needed, with assistance from third-party testing agencies (concrete strength through core sampling, steel strength, masonry strength, etc.)
- Identifying and recommending parts or sections of the structure that may be in need of immediate repair, renovation, and/or replacement
- Expert witness services, as needed
Types of NDT (Non-Destructive) Testing
As required (ultrasonic pulse velocity tests, hammer test, Brinell hardness test, rebar scanning, steel thickness measurement, corrosion measurement)
UPV Test
Measures ultrasonic wave velocity to detect voids in concrete
Hammer Test
Assesses concrete surface strength through rebound of a spring hammer
Covermeter & Rebar Scan
Measures concrete cover thickness and rebar location within the concrete
UTT Test
Measures steel profile thickness using ultrasonic waves
UCT Test
Measures thickness of steel coating using ultrasonic testing
Brinell Hardness
Measures steel hardness by pressing a steel ball into the surface
Torque Wrench Test
Testing bolt tightness in steel structure joints
Dye Penetrant Test
Detects weld joint condition using colored dye penetrant
Types of DT (Destructive Test) Testing
If necessary, with assistance from third-party testing institutions (concrete strength test through core sampling,
steel strength test, brick strength test, etc.)
If necessary, with assistance from third-party testing institutions (concrete strength test through core sampling, steel strength test, brick strength test, etc.)
Core Drill Test
Extracts concrete cores for compressive strength testing
Breakout Test
Breaks concrete to measure the diameter of embedded rebar and its conditions
Carbonation Test
Measures carbonation depth in concrete to assess corrosion risk
Half-Cell Test
Measures the corrosion potential of concrete structures
Chloride Content Test
Extracts concrete powder for chloride content testing
