Esteban Ocon and Pierre Gasly made heavy contact with the wall after they touched following the final grid restart in Melbourne.
The incident caused extensive damage to both cars, but the Alpine factory started immediately replenishing its stock of spares, taking advantage of the three-week break between races.
Szafnauer admits that there was a risk that the extra work might delay the Baku upgrade but in the end, the team was able to stick to its original schedule and make sufficient examples of the new floor parts for this weekend.
He insisted that was one of the positives to be drawn from what was a nightmare race for the team.
"A lot of points were begging, and had that incident happened, say with two races left and you're in a fight for fourth or third or fifth, then it has a bigger impact," he told the F1 Nation podcast.
"But with 20 races to go, three good things came out of that race. One, although aided by DRS, we were able to stay with Ferrari of [Carlos] Sainz, and even without DRS stay ahead of the Aston with Lance [Stroll] in it. So those were the positives from that race.
"And then the other big positive was the fact that as soon as the accident happened, the entire operations here at Enstone got together. They didn't wait for a report of this is damaged, that's damaged, we have to replace these suspension members or a front wing.
"They kind of saw what happened and straight away got out to diverting some of the manufacturing resource into making further spares, but without losing the upgrade that was planned for Baku. And that is a tremendous effort by everybody here.
"So we will be going to Baku with the planned upgrade. And for probably an hour or two before everyone got together it was unsure, because you definitely have to remake spares as a priority over the upgrade.
