Terre Armée in India took advantage of the design customization of its shutter moulds to meet the requirements of the specifications. A single casting yard was set up at Moudha for precasting activity. To further economize the effort, a standard width of 1.75m for the TechCulvert® was accepted, which balanced the benefits of construction efficiency against the challenges posed by handling and transportation of precast units. The precast units were cast simultaneously, inclusive of side walls and slab. The raft was cast in-situ after installation of individual units at the site. This system provided the additional advantage whereby individual units are stitched on top and bottom, allowing the TechCulvert® system to behave monolithically.
The average time for site preparation and installation was 3 days from commencing of excavation to final installation.
