Ref: Technical Specification: RFP Section J Paragraph Attachment 2 – Drawings SOW/Technical Specification/Drawings paragraph/page Drawings C-111 through C-123

Q31. On drawing sheets C-111 through C-123, both the stated scale of 1”=50’ and the graphic scale of 1”=50’ do not match the linear distances depicted by the project stationing, which would indicate an actual scaled drawing of 1”=100’. Please clarify whether we should use the stated scale and depicted scale of 1”=50’, or the scale of 1”=100’ indicated by distances between station numbers, and will the drawings be revised?

A31. Correct the scale is 1” = 100” on the noted sheets
