Q33. While working on the bid for the demolition of buildings 109 & 121 I discovered a question. It looks like where we are installing the new sidewalk and curb will leave a section of the building towards the street without any pavement. I didn’t see any requirement for patching back any asphalt. The picture below show a line where the sidewalk and curb are to be installed.
