Swimming pool pricing - Tile Advice

[JDKitchensandBathrooms]

Hi, im new to the site and unfortunately its a dreaded pricing question. I've been approached to replace 100m2 of a public swimming pool floor. The areas have been already been cleaned out etc and are in a few pockets of 10-15m2 in size. Ive been told the tiles are 300x300 with no mosaics in there

Is there a m2 price for swimming pools and are there any hidden things to look out for? Ive spent ages on google and not been able to find much help

Any advice greatly appreciated
