Beam Depth
It is short by about 5%
You can ask them to provide extra Longitudinal,, 2 bars,, one at top and one at bottom. This can be easily inserted  at bottom  but may nit able to tie ,  top bar can be easily inserted for full length and can be tied easily.

Stps :- shortfall between provided reinf on lesser depth be seen . Balance required shall be placed in form of  L shaped stirrupS to be bent to C shape,  these can be tied at top but at bottom L lower leg shall be approx = beam width front either side. Spacing based on shortfall in stos.
