Even though you do not have prior work experience, doing PGP ACM from NICMAR will always help you and give you an edge in the field of Engineering.
I have friends who joined NICMAR Pune just after UG in Civil Engineering. Some joined ACM and some joined PM at Pune. They pursued their respective course and with exposure to different companies during their internships and industry-satisfying pedagogy they were able to bag placements in Larsen & Toubro.
Do not hesitate to join NICMAR Pune if you get an admission call from them. Just dive into the curriculum and everything is sorted.
