We have executed an Auditorium for Periyar university, and design is highly complicated with sector shape of large span. We gave individual part numbers for the components/parts, as they are unique for complex conditions. We have done the air assembly for the complete erection and handed the project with ZERO defects. The initially proposed structure was a failure ( by another company ) because the clear span was 41 meters. We shouldered the responsibility of completing the project on time despite the delay that happened due to the earlier proposed structure.
