looks like a decent enough job if you need the work. rate for fixing doesnt seem very good to me , but i dont do commercial stuff.
just remember big areas dont necessarily mean big dosh.
some key info missing, like access , who brings stone in, ground floor work or 10th floor with no lift!!
restrictive hours?
Agree jonnyc, rates are not the best. They don't say what stone (its important, some stone takes longer to treat/clean/seal) If they pay same rates per sq.m for steps -wrong. If one step is about 900x200x250 , it makes about 2 steps =1 sq.m. It should be £50-£80 per step and riser, depending on size/finish/profile. Same with wall cladding (different rates). As all members said, there would be 100-200 questions to ask. If somebody was to take on this projet, stoneface should email/fax big fat book with specifications, drawings. But who knows, maby they ok?
Anyway-it's a bit risky
