PUNE: Two weeks after a slab collapse in Chinchwad left eight labourers injured, the Pimpri Chinchwad Municipal Corporation on Monday initiated action against four officials for their negligence in controlling unauthorized constructions.

While junior engineer Sudarshan Wahikar has been suspended and a departmental inquiry initiated against him, the municipal corporation has issued a warning to city engineer M T Kamble. Besides, it has stopped salary increments of deputy engineer Sanjay Kamble and added a note in the service records of executive engineer Makarand Nikam. The corporation had earlier sought explanation from M T Kamble and Nikam. It had also issued show-cause notices to deputy engineer Sanjay Kamble and junior engineer Sudarshan Wahikar.

The incident occurred on March 25 when a slab of an under-construction building in Udyognagar near Chinchwad railway station collapsed. The total construction area was 10,000 sq ft while the land area was 3,000 sq ft. Earlier, municipal commissioner Shrikar Pardeshi had directed Nikam to submit a report on the incident. The report concluded that the construction was unauthorized.

Meanwhile, late in the evening on Monday, some 40 junior engineers staged a protest against the action taken on Sudarshan Wahikar. They said that Wahikar had taken photographs of the unauthorized construction and that further action should have been taken by his seniors. Uday Tekale, assistant commissioner and chief of administration department, said the complaint will be brought to the notice of the municipal commissioner.
