  We find a complete set of 4-point vertices in the Constructive Standard Model
(CSM). This set is smaller than in Feynman diagrams as the CSM does not need or
allow any additional 4-point vertices (or "contact" terms) beyond what is
present in Feynman diagrams and, furthermore, it does $\textit{not}$ need or
allow a 4-point vertex for $Z Z \bar{W} W$, $W W \bar{W} \bar{W}$, $\gamma Z W
\bar{W}$ or $\gamma \gamma W \bar{W}$, in addition to the already known absence
of the 4-gluon vertex. We show that with this set of 4-point vertices,
perturbative unitarity is satisfied in the CSM. Additionally, we show that many
constructive diagrams are not Feynman diagrams rewritten in spinor form. In
fact, we show that there is a significant rearrangement of contributions from
the diagrams in constructive calculations relative to Feynman diagrams, for
some processes. In addition to the already known or expected rearrangement in
diagrams involving external photons, we also find that diagrams involving 4
vector bosons are also significantly different than their Feynman counterparts.
