GENERAL NOTES:

1. DRAWINGS ARE PRODUCED AT ARCH D (24-INCH BY 36-INCH) SIZE.

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.

NOTIFY THE ROOF CONSULTANT OF ANY CONFLICTS BETWEEN EXISTING

CONDITIONS AND THE NEW WORK, OF ANY OMISSIONS OR CONFLICTS IN

THE DRAWINGS AND ANY RESTRICTIONS RELATED TO THE EXECUTION

OF THE WORK INCLUDING THE COORDINATION WITH OTHER TRADES.

4. PRODUCTS PROPOSED FOR USE AND PROJECT WORK SHALL BE IN

ACCORDANCE WITH APPLICABLE FEDERAL, STATE AND LOCAL

GOVERNING ORDINANCES, CODES AND REGULATIONS. NOTIFY THE

OWNER IMMEDIATELY OF CONFLICTS BETWEEN THE SPECIFIED

PRODUCTS AND/OR PROJECT WORK REQUIREMENTS AND CODES,

ORDINANCES AND/OR REGULATIONS.

5. IF DISCREPANCIES ARE DISCOVERED WITHIN THE PROJECT MANUAL OR

DRAWINGS; THE OWNER, NOT THE CONTRACTOR, SHALL DETERMINE

THE INTENT OF THE DESIGN AND PROVIDE CLARIFICATION. NO

ALLOWANCE SHALL BE MADE FOR CONTRACTOR MISINTERPRETATION

OR IMPLIED MISINTERPRETATION OF THE PROJECT MANUAL AND

DRAWINGS.

6. REFER TO THE PROJECT MANUAL AND ROOFING SYSTEM

MANUFACTURER WRITTEN INSTRUCTIONS FOR FURTHER CLARIFICATION

OF PROJECT REQUIREMENTS. NOTIFY THE OWNER IMMEDIATELY OF

CONFLICTS BETWEEN THE SPECIFIED DESIGN REQUIREMENTS AND THE

WRITTEN REQUIREMENTS AND RECOMMENDATIONS OF THE ROOFING
