STRUCTURAL AUDIT is a means of determining the existing defects present in the building’s structure, the ways and means of rectifying these defects & the optimum cost required to rectify these defects.
The existing defects will determine the further life span of the building, and the STRUCTURAL AUDIT will also determine the further addition to the existing life span of the building after the defects pointed out in the structural audit have been rectified.
Sample Structural Audit
The buildings are visited and inspection carried out for:
A] STRUCTURAL DEFECTS & FAILURES.
B] SEEPAGE & LEAKAGE DEFECTS.
C] PLASTER DEFECTS.
D] PLUMBING DEFECTS & LEAKAGES
In India there are many old buildings which have reduced strength in due course of time. If further use of such deteriorated structure is continued it may endanger the lives of the occupants and surrounding habitation. Appropriate actions should then be implemented to improve the performance of structures and restore the desired function of structures. Thus, it is utmost important to perform structural audit of existing buildings and to implement maintenance/ repair work timely which will lead to prolonged life of the building and safety of the occupant. To act more responsible and preemptive towards the dilapidated buildings, the municipal corporation must issue notices to the buildings and co-operative societies which are more than 30 years old to carry out mandatory structural audit and submit the audit report. Structural audit should highlight and investigate all critical areas and recommend immediate remedial and preventive measures. It should cover the structural analysis of existing frame and find critical elements for all types of loadings. It also helps in delivering a strong building structure with cost effective solutions and appropriate maintenance program.
This paper deals with study of different parameter of structural audit including visual inspection, non-destructive testing, core sampling and testing. It also emphasizes on different repairs and retrofitting measures to be used for buildings after structural audit.
What is Structural Audit?
Structural Audit is an overall health and performance checkup of a building like a doctor examines a patient. It ensures that the building and its premises are safe and have no risk. It analyses and suggests appropriate repairs and retrofitting measures required for the buildings to perform better in its service life. Structural audit is done by an experienced and licensed structural consultant.
Purpose of Structural Audit
– To save human life and buildings
-To understand the condition of building
– To find critical areas to repair immediately
– To comply with statutory requirements
– To enhance life cycle of building by suggesting preventive and corrective
measures like repairs and retrofitting
As per clause No.77 of revised Bye-Laws of Cooperative Housing Societies: “The Society shall cause the ‘Structural Audit’ of the building as follows:
? For building aging between 15 to 30 years once in 5 years
? For building aging above 30 years Once in 3 years.
The structural diagnosis is vast, important and highly responsible job which is connected with lives of human beings. It is mandatory and advisable to carry out the periodical structural audit of the buildings by professional experts and act immediately through recommendations provided in audit report. The success of repairs and restoration is always based on thorough knowledge, correct diagnosis and in-depth studies of problems in building, proper repair practices and finally socio-economic considerations. The effective implementation of auditing enhances the life span of structure, prevents deterioration of building leading to sustainability.
