A one-stop over-exposure is significant for Provia 100F, but nowhere near a calamity like when using Velvia 50 or 100. I would ask the lab for a clip test of the first two or three frames and leave it to your judgement (and/or theirs) as to how the rest should be processed. I have over-exposed it by accident +0.3 to +0.5 and it has held up well, but this emulsion, like the Velvias, favours diffuse illumination, not bright sunlight, so you proceed with caution. Though photographers do push/pull Provia and Velvia, there will always be a casualty with getting a sub-optimally exposed film over the line.
