Condor

The CONDOR formwork system for casting  natural circular tunnels is made up of a structure with OMNI steel beams, allowing the passage of site vehicles and representing the supporting steel structure to which the formwork is connected.‎ The formwork is made of: OMNI UPN 120 profiles, SH20 wooden beams, 3-ply wooden shapes and birch plywood with phenolic coating.‎ It includes all accessories, such as work platforms, walking decks, stairs, all complying with strictest safety standards.‎ The formwork includes useful accessories, such as casting docks with fast connection to the concrete pump and inspection windows to check the filling of the concrete inside the formwork.‎ The concrete wall vibration system allows to cost a very high quality finished surface.‎ Once the whole structure is lowered with a hydraulic system and the inferior lateral panel are stripped, the cart moves forward through wheels rolling on common tracks, by towing with means already available in the site.‎ The system has a significant versatility, thanks to OMNI structure’s features allowing by simple and fully reversible modifications, adaptation to widening compared with current sections, due to lay-bys, large chambers, emergency niches and accesses with sloping portals.‎ The shift to the casting of artificial tunnels occurs by simply adding the external formwork.‎ CONDOR pays careful attention to services offered to the client, such as dedicated design, pre-assembly of modules in the warehouse in order to ensure perfect curve cut of shapes and joint sealing, on-site technical support in any phase, on-site training and information workshops for the staff.‎
