Comments from Prof. A R Chandrasekaran:

Necessarily funding for Rehab has to come from Govt or International
agencies like World Bank, etc. and it is most unlikely a builder of that
structure would be involved in the Rehab work.

I am aware of a case history of Rehab of Elevared Water tanks in Delhi. Even
though the original structures were built by Govt agencies like DDA, etc.,
no data was forthcoming. The tender required the agency wishing to Rehab to
determine reinforcement existing in columns & braces as well as foundation
details by non-destructive methods.

I doubt, therefore, very little data would be forthcoming from private
builders. There is then the vexed problems of legal matter.

Even where Rehab is not involved, but for some research study we are
carrying out on dynamic behaviour, I find it almost impossible to get any
data from builder/engineer except some of them permit us to measure the size
of columns and beams.
It is very difficult to get information on the foundation or the mix of
concrete. The question of getting reinforcement details is next to
impossible. Is any builder/engineer volunteering to help us to provide data
for research work at Hyderabad

The draft code is well written based on International practices.

It will be a good idea for this econf to debate the points I have raised for
implementation of rehab

Thanks
ARC
