slab, beam, wall, etc. to determine whether any embedded items such as conduit and
reinforcing steel would be cut or disturbed and provide X-rays to COTR. If the
cutting/core drilling will cut any conduits, notify the COTR to re-locate the opening or
take other action as required. If reinforcing steel is encountered, notify the COTR to
either re-locate the opening or evaluate the effect of cutting the reinforcement. Perform
this evaluation by a registered professional engineer licensed in the Commonwealth of
Virginia. Refer to Division 01 Section “Summary” for utility outage requirements.
6. Structural Elements: Where cutting and patching involve adding reinforcement to
structural elements, submit details and engineering calculations showing integration of
reinforcement with original structure. When cutting and patching involves welding or
open flame cutting, obtain the approval of The Authority's Fire Marshal for such work
prior to its start. Before cutting or drilling a structural element, X-ray the element to
determine whether any embedded items such as conduit and reinforcing steel would be
cut or disturbed and provide X-rays to COTR. If the cutting/drilling will cut any rebar or
conduits, notify the COTR to re-locate the opening or take other action as required. If
reinforcing steel is encountered, notify the COTR to either re-locate the opening or
evaluate the effect of cutting the reinforcement. Perform this evaluation by a registered
professional engineer licensed in the Commonwealth of Virginia.
7. COTR's Approval: Obtain COTR’s approval in writing of cutting and patching proposal
before cutting and patching. Approval does not waive COTR’s right to later require
removal and replacement of unsatisfactory work.
1.5 QUALITY ASSURANCE
A. Structural Elements: Do not cut and patch structural elements in a manner that could change
their load-carrying capacity or load-deflection ratio.
B. Operational Elements: Do not cut and patch the following operating elements and related
components in a manner that results in reducing their capacity to perform as intended or that
results in increased maintenance or decreased operational life or safety. Obtain COTR's written
approval of the cutting and patching of the following operating elements or safety related items:
1. Primary operational systems and equipment.
2. Air or smoke barriers.
3. Fire-suppression systems.
4. Control systems.
5. Communication systems.
6. Conveying systems.
7. Electrical wiring systems.
8. Security systems including CCTV and duress alarms.
9. Baggage handling systems.
C. Miscellaneous Elements: Do not cut and patch miscellaneous elements or related components
in a manner that could change their load-carrying capacity, that results in reducing their
capacity to perform as intended, or results in increased maintenance or decreased operational
life or safety. Miscellaneous elements include the following:
1. Water, moisture, or vapor barriers.
2. Membranes and flashings.
