Some owners perform audits solely to meet compliance requirements, for some, it is driven by some “distress observed” in the structure, and the more enlightened ones do it as a “good practice” and a “preventive measure”.

We are a team of structural auditors engineers having licenses from (NMMC, MCGM, BMC, and others) to carry out condition assessments of commercial buildings, residential buildings, industrial and infrastructure projects.

GEM Engserv is a leading crack diagnostic consultant in Mumbai and has worked on over 200+ structural audit assignments in India. One of our largest assignments for structural audit was from Tata Capital Financial Services for their PAN INDIA offices.
