The biggest expenditure is maintenance of infrastructure viz roads etc. The GIDC board had taken a decision that before a contractor was paid finally, a certificate of completion would be taken from the respective industrial estate association. From 2015 onwards there was rush of road contracts issued and not one on them has any completion certificate, so technically all are illegal. The Government should audit each contract in terms of scope of work, when was Board approval taken and for how much, any enhancement given and why. This is the major areas where GIDC funds are wasted.
