B. Related Sections include the following: 1. Divisions 2 through 16 Sections for specific requirements and limitations

applicable to cutting and patching individual parts of the Work. 2. Division 7 Section "Through-Penetration Firestop Systems" for patching fire-rated

construction.

1.3 DEFINITIONS

A. Cutting: Removal of in-place construction necessary to permit installation or performance of other Work.

B. Patching: Fitting and repair work required to restore surfaces to original conditions after installation of other Work.

1.4 SUBMITTALS

A. Cutting and Patching Proposal: Submit a proposal describing procedures at least 10 days before the time cutting and patching will be performed, requesting approval to proceed. Include the following information: 1. Extent: Describe cutting and patching, show how they will be performed, and
