· The Technical Factors attachment, paragraph A2, references,”…successfully removed and painted a minimum total of 200,000 square feet of pavement markings on an active airfield within a five-day period..” Is the intent to show the ability to remove rubber and paint markings, not remove markings? Removing 200,000 square feet of pavement markings would take substantially longer than 5 days. Reference applies to a combination of both removal and painting. 200,000 square feet is not a single requirement for both as long as the square footage of both equals the 200,000.
