The figures and drawings below show the floor plan & section of a laboratory structure. The structure comprises steel beams and columns supporting a reinforced concrete slab, all supported onto reinforced concrete pad foundations. The building is enclosed with $220mm$ brick walls on all $4$ sides and a timber roof $(30\frac{kg}{m^2}).$

The first floor is a $250mm$ reinforced concrete floor supported on steel beams that span between columns as indicated. The steel beams have shear studs cast into the slab $($the purpose of the shear studs is for lateral stability and not composite design$).$ The floor has a finish of $30mm$ screed of weight $2200k\frac{g}{m^3}.$ The soffit of the slab has a $25mm$ plastered finish of $2300k\frac{g}{m^3}.$
