Biggest:
This is one wall on a 7 tower site. If I remember right it was close to 75000m²(800ksq.ft-ish). Myself and 4 other masons rocked it.
Proudest:
The customer had to be talked out of going with 1mm joints. They settled for 5-10mm. This is cladding, pin and bracket mechanical. If it had been full depth stone, 200+mm, we probably could have done it. The stone was more in the range of 75mm+/- and we needed the room to accommodate the brackets.
That was how it was explained to me...3 days ago. 5...5 entire years I've been using it wrong. 🤦
