Grades and elevations, are there any new grades to meet? Or are we to match the finish paving along the building’s lines and sidewalks as well as the asphalt perimeter?

No specific grades or elevations to meet, as long as asphalt topcoat is not higher than existing sidewalks or metal trim on building. Water needs to run away from building. It is preferred that asphalt topcoat meets sidewalk elevations as much as possible.

Conforming at the asphalt edge, are there any special requirements, grinding or just feather the new to the existing?

Contractor responsible for proof and submission to government that 95% compaction has been achieved.

Will a staging/laydown area near Bldg. 663 be provided for equipment and materials? Are there daily parking restrictions or delivery hour restrictions for asphalt trucks?
