	My specific question is, how do we do shuttering work for Invert beam if we are planning to do concreting with the slab and not separately. Shuttering board from outside can be supported but how do we give support towards inner side of the invert beam

	Er, um, after taking site-specific advice from a qualified Civil Engineer, perhaps? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	I'm not exactly sure from your description, but the shuttering for the inverted beam can be supported by "saddles" that straddle over the top of the beam shuttering to stop them spreading. If you are concerned about "sag" across the span, then you might need to have an "I" beam that spans the total pour that suspends the shuttering and can be removed once the concrete has cured (not just set). Note this beam is only to support the shuttering and not the slab/beam during cure. You might consult local "formwork carpenters" for their advice. They often face challenges through their career, like tapered curved formwork for reservoir outlets. __________________ Just an Engineer from the land down under.

	Exactly how does this single question relate to the entire cross-sections of the entire structure?... What geographic location? Under what Code(s) is the work to be done? etc. Not enough detail provided in order to provide a complete answer... __________________ ''illigitimi non carborundum...''(i.e.: don't let the fatherless (self-deluding,sabotaging, long-term-memory-impaired, knee-jerking, cheap-shotting, mono-syllabic, self-annointed, shadow-lurking, back-biting, off-topic-inquisitors) grind you down...)
