Third Party Structural Audit Report (AT Report) & Building Fitness Survey
Independent structural audit, Building Fitness Survey (BFS), Structural Health Audit and compliance-ready AT Reports for residential, commercial, industrial and telecom structures.
Anubha Chouhan Associates Pvt. Ltd. (acApl) provides independent Third Party Structural Audit Reports (AT Reports) for buildings and telecom installations.
A Third Party Structural Audit is an unbiased engineering evaluation conducted to verify structural safety, load carrying capacity, material condition, and compliance with applicable IS codes.
Our audit reports are prepared by qualified structural engineers and are accepted by municipal authorities, telecom operators, infrastructure providers, housing societies and industries.
What is a Third Party Structural Audit (AT Report)?
An AT Report (Audit Report) is an independent structural safety assessment carried out by a licensed structural engineer to certify whether a building is:
- Structurally safe
- Conditionally safe (requires repair or retrofitting)
- Structurally unsafe and requiring urgent intervention
AT Reports are often mandatory for:
- Municipal compliance and safety certification
- Old buildings (15–30+ years)
- Redevelopment and rehabilitation projects
- Insurance and due diligence audits
- Rooftop telecom tower installation approvals
- Industrial and factory safety compliance
Scope of Third Party Structural Audit
- ✔ Detailed visual structural inspection
- ✔ Crack mapping & distress identification
- ✔ Concrete spalling & corrosion assessment
- ✔ Reinforcement mapping & detailing
- ✔ Non-Destructive Testing (NDT)
- ✔ Core cutting & strength validation (if required)
- ✔ Load carrying capacity verification
- ✔ Wind & seismic compliance check
- ✔ Factor of safety calculation
- ✔ Structural modelling using STAAD Pro
- ✔ Photographic documentation
- ✔ Structural Safety Certificate issuance
Non-Destructive Testing (NDT) in Structural Audit
Our Third Party Structural Audits are supported by advanced Non-Destructive Testing methods including:
- Ultrasonic Pulse Velocity Test (UPVT)
- Rebound Hammer Test
- Rebar Scanning / Cover Meter Test
- Carbonation depth testing
- Half-cell potential test (if required)
- Core extraction & compressive strength testing
NDT data is integrated into Building Strength Assessment and Structural Stability Testing (SST) .
Third Party Structural Audit for Telecom Towers (RTT / RTP / GBT)
We conduct independent structural audits for:
- Rooftop Telecom Towers (RTT)
- Rooftop Poles (RTP)
- Ground-Based Towers (GBT)
- Multi-operator infrastructure sharing
- Tower augmentation projects
Supported by Telecom Tower Load Analysis and Soil Investigation Reports where required.

Frequently Asked Questions – Third Party Structural Audit
Is a Third Party Structural Audit mandatory?
Yes. Many municipal bodies require periodic structural audit for old buildings and high-rise structures.
What is the difference between BFS and AT Report?
BFS (Building Fitness Survey) evaluates building condition, while an AT Report is an independent third-party certification issued for regulatory compliance.
How often should a structural audit be conducted?
Typically every 5 years after a certain building age, or before redevelopment or telecom tower installation.
Can a structural audit recommend retrofitting?
Yes. If structural deficiencies are identified, retrofitting and strengthening solutions are recommended.
Do you issue structural safety certificates?
Yes. We issue compliance-ready structural safety certificates as part of the Third Party Structural Audit Report.
