The two additional lines, not present in Table 1.18 and here highlighted in bold, correspond to the moment and to the vertical
load resulting from the surcharge above the footing.
The max pressure on ground is achieved once again for the second combination and its value
is here higher than the one calculated in the previous scheme.
