Structural Audit

What is a structural audit?

The meaning of ‘structural audit’ is an examination of the overall health of a building to ensure that it is safe, risk-free and habitable. The purpose of a structural audit is to correctly identify parts or sections of a building that may need immediate repair, renovation, or replacement. Structural audits are performed by licensed consultants who have the required expertise in civil construction and are impanelled with the government authorities.

A structural audit is government-mandated. For buildings that are between 15 to 30 years old, the statutory requirement is to conduct a structural audit once in 5 years. For buildings over 30 years, a structural audit must be conducted once every 3 years. The said durations begin from the date the completion certificate/occupation certificate was issued or since at least 50% of the occupation of the built-up area, whichever comes first.

Purpose of the Structural Audit 

To enhance the overall lifecycle of the building, its components need to be periodically examined so that there is no danger to its inhabitants. Areas in need of crucial repairs need to be identified to employ corrective measures so that the day-to-day life of the residents is not inconvenienced on account of unexpected leakages or breakages.

In the probable scenario that the builder has cut corners and left any sections of the building prone to collapse or faster dilapidation, a structural audit is your best bet to avert any disasters. Even if the building is relatively sound in its basic framework, it is likely that during a preceding repair or renovation, less-than-ideal quality materials were used that have led to further damage or leakage. In cases where continuous neglect from the stakeholders persists, it may happen that a massive redevelopment project needs to be undertaken, costing the residents an exorbitant amount of money. A structural audit is a highly recommended preventive measure to avoid any calamitous eventualities altogether.

What are the stages of a structural audit?

To begin with, the society needs to hire a Project Consultant/Agency after inviting tenders from prospective service providers. The estimated repairs or preventive actions need to be approved in a general body meeting. Once an agency is appointed, it is the responsibility of the society’s committee to provide them with all the pertinent details, plans and designs of the building including information on any previous reparations and maintenance history. Below are the phases and techniques of a structural audit.

1. Visual Inspection

The first stage of a structural audit consists of a visual inspection that should lead to the identification of defects, material degradation, and deformation of any sections or interior components. If alterations, additions or replacements are needed, they should be identified during the visual inspection too.

All elements of the building are examined, including but not limited to,columns, beams, slabs, balconies, false ceilings, roofs, parapets, railings, rooms, bathrooms, kitchens, lofts, mezzanine floors, stairways, water tanks,storage, plumbing lines, drainage lines. These inspections are carried out in order to ascertain cracks/deflections in retaining walls, leakages, and concrete durability. Dampness in the walls is also inspected along with varying loads on the structure that may have occurred. Additionally, soil bearing capacity is determined through pit trials or from soil data of the vicinity.

2. Non-destructive Testing

The structural integrity of a building is initially determined by the visual inspection; however, the strength and durability of concrete is an essential factor that decides its longevity and safety. For this purpose, non-destructive testing (NDT) should be carried out to check concrete strength, chemical attack resistance, corrosion assessment, among other things. Below are the common techniques to assess whether your building’s concrete will stand the test of time.

Rebound hammer Test on beams, slabs, etc. to check the compressive strength of the concrete.

Ultrasonic pulse Velocity Test to inspect cracks and to test the quality of concrete and natural rocks in the building.

Core testing consists of a method in which samples are tested in a laboratory to determine strength.

Chemical tests are performed to check carbonation and pH, water/acid soluble chloride and sulphate contents of the concrete.

Rebar locators and cover meters are used to check the cover, diameter and reinforcement of steel

Water permeability test is carried out to check the resistance of concrete underwater pressure.

A half-cell potential test is done to check corrosion or the possibility of it in the steel.

Some other popular tests in current practice are Leak Testing, electromagnetic testing, Laser Testing, Magnetic Particle Testing, etc.

Earthquake resistance (seismic diagnosis test) and fire readiness (fire fighting system analysis) is measured and analysed by the structural auditors in addition to the above-mentioned tests.

3. Analysis Report

A structural audit report is presented to the society by the consultant details the following:

Recommendations for repairs based on the assessment of deterioration, breakage, and materials

Retrofitting, and restoration measures to bring the damaged components up to the required standard

Strengthening the current components of the building to make it more resistant to collapse and increase its load-bearing capacity

The consultant provides the cost of labour, materials, equipment, and overall services to the society in the audit report, and offers expertise on future maintenance and cost-effective measures to slow down future deterioration.
