PLEASE NOTE AND VERIFY THE SCALE INDICATED ON EACH DRAWING.

NOTE THAT ROOF PLANS AND OTHER PROJECT DRAWINGS PRODUCED

ON OTHER PAPER SIZES MAY NOT BE CORRECTLY SCALED.

2. ALL COMPONENTS SHOWN ON PROJECT DRAWINGS ARE NEW UNLESS

SPECIFICALLY INDICATED AS EXISTING.

3. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO VERIFY EXISTING

PROJECT SITE CONDITIONS. THESE CONDITIONS INCLUDE, BUT ARE NOT

LIMITED TO: BUILDING DIMENSIONS AND PROPOSED PROJECT STAGING

LOCATIONS, ROOF REPLACEMENT AREA DIMENSIONS, ROOF DRAINAGE

COMPONENT LOCATIONS, ROOF PENETRATION LOCATIONS, EXISTING

ROOF SYSTEM COMPONENT MAKE-UP AND THICKNESS, AND PROJECT

REPAIR QUANTITIES (IF APPLICABLE). THE CONTRACTOR SHALL VISIT

AND BECOME FAMILIAR WITH THE SITE AND BUILDING PRIOR TO

PROPOSAL SUBMISSION. INCLUDE THE COST OF ALL WORK DESCRIBED

IN THE BIDDING DOCUMENTS AND THAT IS REQUIRED OR REASONABLY

IMPLIED TO ACHIEVE THE DESIGN INTENT OF THE BIDDING DOCUMENTS.
