taken and advice re tendering due to stony or unstable conditions.  All proposed bidders are encouraged to attend.  Bidders are advised to read the Special Provision  on Drawings 14 & 15 re payment considerations for stony conditions.  This Special Provision may or may not be modified  by the addendum that is to be issued.  The contractor is to acknowledge,  where required, receipt of any addenda.
