So then contractors were engaged to put two huge noisy fans in the ceiling to pump the cold air out through the roof.That didnt work either.Someone had forgotten that to get air out,it has to get in.
So then two huge holes were cut in the side outside wall of the plant room,and covered with heavy duty mesh.
Now there was hot water for the showers,but the fans had to be fitted with time clocks,that cycled them off at night, so the non paying tenants could get some sleep.
I could write a book about all the stuff ups i have seen over the years.Some have been huge.
In another life,when i did comissioning,very often it was up to us to explain to the consultant engineer why this (whatever it was) had no chance of ever working.
In those days,some of the engineers were very good,but these days finding one that has any idea is like looking for rocking horse poo.
