INDICATED. THE ASBESTOS INSPECTION REPORT IS INCLUDED AS AN APPENDIX TO THE

PROJECT SPECIFICATIONS. ASBESTOS-CONTAINING BUILDING MATERIALS SHALL NOT BE

DISTURBED IN THE WORK EXCEPT WHERE SPECIFICALLY INDICATED AND REQUIRED. WHERE

SUCH ACTIONS ARE REQUIRED, THE CONTRACTOR SHALL HAVE THE ACM REMOVED BY A

LICENSED ASBESTOS CONTRACTOR USING APPROVED PROCEDURES AS SPECIFIED. THE

WORK REQUIRED FOR ASBESTOS ABATEMENT IS PERMITTED WITHIN THE OVER ALL BUILDING

PERMIT ISSUED. THE ACM THAT IS TO REMAIN AND THE NEW NON ASBESTOS CONTAINING

MATERIAL SHALL BE LABELED ACCORDINGLY. THE ASBESTOS ABATEMENT CONTRACTOR

SHALL MARK UP THE AS-BUILT DRAWINGS RESULTING FROM ITS WORK TO INCLUDE AREAS

HERE ASBESTOS WAS ABATED, AREAS WHERE ASBESTOS WAS ENCAPSULATED, AND AREAS

WHERE ACM EXIST BUT WERE LEFT IN PLACE. THE GENERAL CONTRACTOR SHALL REVIEW
