This shell roof industrial building houses the heat treatment plant of Tractor Engineers Ltd. (TENGL), a wholly owned subsidiary of Larsen & Toubro Limited. The scope of work included excavation, leveling & filling works, heavy machinery foundations, RCC frames structure, industrial floorings, elevated water tank, shell type roof, drainage, pluming and other area development works.

The critical part was the shell roof construction of 20 mtr span with shell thickness of just 75 mm. Controlled concrete mix design with proper workability was used to get the form finish along with necessary camber which was then carefully lifted by hydraulic cranes.
