In the pre-independence era, there was a British Ammunition center in the visinity of Asansol. The present day workshop is built on the same premises. After departure of  British rulers the ammunition centre was converted into  a technical Institute  bringing technical material from the nearby aerodrum  at Nigahi.
 A sandwich pattern course in Electrical-Mechanical was first started  in the workshop premises. It was  due to  the  huge technical  manpower shortage after independance . Dr.Bidhan Chandra Roy constructed the main building and it was converted into Asansol Polytechnic in  the year 1950 with 2 Part time courses in Mechanical and Electrical and a separate ITI unit known as Asansol Junior Polytechnic. The  Mining Engg. dept. was opened in the year 1958. Later Metallurgical Engg on 1981 ,  Mining Survey on 1995, regular Electrical Engg. on 2008, regular Mechanical Engg. on 2009 and Civil on 2013. The Part time Mechanical and Electrical courses were discontinued since 2014.
