$1)$ Use the LRFD method and the AISC Composite Design Tables to select the

lightest W section for beam B$1$ and girder G$1.$ For B$1,$ use maximum $70\%$

composite action and limit beam depth to $12$ in$.$ For G$1,$ use $50\%$ composite

action and limit girder depth to $16$ in$.$

$2)$ Check whether the selected beam and girder can support loads during construction.

$*$Do not check shear or deflection. Do not design connectors.
