Mr. Phelim Devine:

For context, there are about 6,000 drawings in the project in total. That is the drawing set. They get revised for different reasons. Because it is a public works contract, we cannot set out particular products and systems. We can give out performance specifications and overall design intent but the contractor may say that it will use a particular product - a wall, ceiling or facade - and that causes drawings to be updated to reflect that. At the end of the project, we need to have a full and complete set of as-built drawings and drawings for regulation-----
