The PEC University of Technology, Chandigarh was originally established as Mugalpura Engineering College at Lahore (now in Pakistan) on November 9, 1921. The name of the college was later changed to Maclagan Engineering College and it started functioning under the name on March 19, 1924. In the year 1931, the college was affiliated to Punjab University, Lahore. After partition in 1947, the college was shifted to Roorkee (India) and was renamed as East Punjab College of Engineering. In the year 1950 the word East was dropped and it came to know by its present name – Punjab Engineering College.

In 1994 this institution was adjudged the best technical college in India by the National Foundation of Engineers. It occupies an area of 146 acres. Up to 1962, the college consisted of engineering departments of Civil, Electrical and Mechanical Engineering. Thereafter the college expanded and five new departments in the fields of Aeronautical Engineering, Electronics and Electrical Communication Engineering, Metallurgical Engineering, Production Engineering and Computer Science Engineering were added gradually. Recently a new department of Information & Technology has been added. In the year 1957, Highway Engineering was added as the first post-graduate course in the college. Gradually other post-graduate courses were subsequently added. Presently there are eleven post-graduate courses leading to Masters of Engineering degree in Highways, Structures, Hydraulics and Irrigation, Rotodynamic Machines, Electrical Power Systems, Environmental Engineering (Interdisciplinary), Electronics Metallurgical Engineering and C.I.M. Facilities for post-graduate studies exist for regular as well as for part-time students.
