Opening dimensions	Framed opening matches the approved width and height within the tolerance stated in the approved detail
Square and plumb	King studs plumb and header level within the tolerance stated in the approved detail; opening corners square within the same tolerance
Utility clearance	No wiring, plumbing, gas line, or duct in contact with, or damaged by, framing members or fasteners
Concealed-condition acceptance	Every concealed condition found differs from the approved scope only where a documented change order has been approved
Finish integration	Restored wall surface matches surrounding texture, sheen, and color under normal and raking light

E. Preparation — Verification and Layout (Steps 1–8)

1. Obtain the approved opening dimensions, location, purpose, finish detail, framing detail, and required permits or inspections. Record the finished-opening width and height, the framing detail reference, and any permit or inspection requirement on the framing record before proceeding.
2. Verify through plans, field investigation, and qualified evaluation that the wall is non-load-bearing and is not a shear wall, braced wall panel, fire-rated assembly, smoke barrier, garage separation, shaft, party wall, plumbing wall, duct chase, or protected egress element. Record the verification source, verifier, and date on the Verification and Boundary Record. Stop if any source is unavailable or if two sources conflict.
3. Verify ceiling, floor, roof, joist, truss, beam, post, and foundation relationships above and below the opening. Record the framing direction and bearing condition observed above and below the wall from the field investigation.
4. Locate and identify wiring, plumbing, gas, ducts, vents, communications, alarms, and fire blocking using approved methods and exploratory access. Mark each identified route on the wall face and record it as a suspected or confirmed condition on the risk register.
5. Stop if any structural or utility condition is uncertain or conflicts with the approved opening. Do not proceed to Step 6 until the conflict is resolved through the approved change-control process.
6. Complete hazardous-material assessment before cutting the wall finish. Confirm the assessment result is recorded and any required abatement is complete before layout begins.
7. Coordinate relocation of any permitted utilities through approved designs and qualified trades before framing the opening. Record the qualified trade, scope, and completion date for any utility relocation required by the approved design.
8. Protect the room and establish containment, lighting, access, and debris controls. Confirm the Chapter 2 containment and dust-control setup is in place and functioning before marking either wall face.

F. Layout and Exploratory Access (Steps 9–13)

1. Lay out both faces of the opening from common level and plumb references. Establish one level line and one plumb line common to both wall faces and mark the opening from those references, not from independent measurements on each face.
2. Verify the finished opening size accounts for framing, drywall or panel thickness, corner bead, jamb, trim, and required clearances. Add each layer's thickness to the approved finished dimension per the Measurement Cue above and record the resulting framed rough-opening size.
3. Mark cut lines and exploratory openings. Mark the full opening boundary and at least one smaller exploratory cut location within that boundary before committing to the full-size cut.
4. Create controlled exploratory openings to confirm stud locations, utilities, blocking, and wall thickness. Cut the exploratory opening to a controlled depth and inspect it before enlarging the cut.
5. Revise the layout only through the approved change-control process. Document any layout change and the reason before marking the revised cut lines.

G. Wall-Face Removal and Concealed-Condition Inspection (Steps 14–17)

1. Score finish layers and cut the first face to a controlled depth. Score paint, texture, and joint compound along the cut line before cutting through the drywall or panel to the marked boundary.
2. Remove drywall or panel sections in manageable pieces while preserving retained edges. Support each removed section as it is released and set it aside without damaging the retained wall edge.
3. Inspect the full opening area before cutting any stud. Confirm every identified utility, fire-blocking member, and stud location visible in the exposed cavity matches the Step 4 record before proceeding.
4. Install temporary protection or bracing where the approved plan requires it, even in a non-load-bearing partition. Install any temporary support the approved framing detail specifies before removing a stud that provides lateral bracing to adjacent finishes.

H. Framing (Steps 18–23)

1. Cut only the studs identified in the approved framing detail. Confirm each stud against the approved detail before cutting; do not cut a stud that is not specifically identified.
2. Do not cut top plates, bottom plates, adjacent studs, fire blocking, or concealed structural members unless expressly detailed. Stop and revise the scope through change control if the approved detail did not anticipate a member that must be cut.
3. Install approved king studs, trimmers, sill, head framing, blocking, and perimeter members for the non-structural opening. Install each member in the sequence specified by the approved detail, verifying plumb and level before fastening.
4. Fasten framing using the specified method without splitting members or contacting utilities. Use the fastener type, size, and spacing from Section C, and verify clearance from every utility identified in Step 4.
5. Verify opening width, height, square, plumb, framing plane, and attachment. Measure the framed opening against the Section D acceptance standards before covering any framing member.
6. Complete required framing and utility inspection before closure. Do not proceed to Section I until any required inspection has been scheduled or completed per the Code Alert above.

I. Wall Restoration and Finish (Steps 24–29)

1. Restore insulation, fire blocking, acoustic treatment, vapor control, or other wall components required by the approved assembly. Install each required component per the approved assembly before closing the wall.
2. Install matching drywall or finish panels with supported edges. Cut and dry-fit the patch panel per the Chapter 5 drywall-repair standard before fastening.
3. Install corner bead, jamb material, returns, casing, or edge trim according to the approved finish design. Fasten or embed each component per the manufacturer's instructions and the approved finish design.
4. Tape, coat, sand, prime, and paint repaired wall surfaces in the correct sequence. Follow the Chapter 5 taping and Chapter 10 paint-integration sequence for every restored surface.
5. Finish exposed framing or jamb surfaces and protect all cut edges. Apply the specified finish to any exposed framing or jamb edge before the opening is placed into use.
6. Inspect structural verification records, framing, opening dimensions, wall restoration, corners, trim, finish, utility clearances, and adjacent damage. Complete this inspection using the Section D acceptance standards before Section J.

J. Documentation and Closure (Step 30)

30. Document photographs before closure, inspection approvals, framing details, products, and final acceptance. File the completed verification record, framing photographs taken before drywall closure, inspection approvals, and final acceptance together with the room's Chapter 1 documentation package.
