Even this challenging situation would ease
The main reason for such strong buildings total dedication, no adulteration in construction materials, moral fear which are totally lack in the present constructions. There is a saying in practice about telling the construction as 'my father constructed this house with involvement by seeing every brick'. But now many people constructs their own house itself without much care and handover to other people as if they have no time. Many intermediaries also misused their production items which are used for construction, they are seeing their purse rather than the stability of building. During the year 1636 a grand mahal was constructed in Madurai by then King Thirumalai Naick and later it was used as his Palace for administration. Still this Palace is there with worth seeing. Albert Victor Bridge in Madurai across the vaigai river constructed before 126 years back is still in use for transportation. These are all examples of their dedication and involvement and care.
But nowadays the construction activities are done so fast and enough curing time is also not given. They ratios of ingredients also changes as per the rate and convenience. Workers also want to complete the work as fast as possible and they never bother about quality.
These are the reasons which comes to my mind for the difference in longevity of constructions.
