The Calcutta Electric Supply Corporation (CESC) has a campus located on Garden Reach road in Kolkata, West Bengal. Larsen & Toubro Construction were tasked with building a pump house within the campus.

Heritage Infraspace assisted them with a single-basement diaphragm wall construction for the structure. Despite there being structural and logistical challenges at the site, we were able to complete the project in just over 2 months.
