Costs for the production of a KS bond coat

Hello everyone,

for the construction of our external walls made of sand-lime brick in the format 3DF, a sand-lime brick key layer was calculated by my general contractor as the lowest row of bricks. However, this is now omitted because the thermal separation between the base plate and the masonry is realized differently. The key layer was originally supposed to run around the entire edge of the base plate, the circumference is 43 m.
Can you estimate the approximate costs for the production of such a first brick layer?

Thank you very much
Best regards
Dennis
