Job Overview

This project qualifies you to inspect one kitchen, vanity, closet, or practice installation area for wall, floor, ceiling, and dimensional conditions, locate the studs and concealed services that will control cabinet fastening, verify every cabinet dimension against the approved plan, and issue a documented cabinet-installation readiness and correction plan. The finished work product is a field-verified installation-area survey — a signed cabinet-readiness record accompanied by a field-verified layout sketch and deficiency list — ready to support the reference-line layout completed in Project 03 and the cabinet installation completed in Projects 4 through 6.

You will obtain the controlling documents, confirm the finished-floor condition, inspect walls for plumb and flatness, inspect the floor for level and damage, inspect ceilings and soffits where tall or wall cabinets approach them, verify room and cabinet dimensions against the plan, locate studs and backing, identify plumbing, electrical, gas, and mechanical obstacles, confirm continued utility access after installation, check door swings and accessibility, identify conditions requiring correction, and issue a documented readiness decision.

This project is the first project in Book 13 and assumes the room arrives with framing, drywall, and finished flooring installed, and with rough plumbing and electrical in place, under the applicable framing, drywall, and flooring books in this series. It sits immediately before Project 02, which stages the protected work area that this project's readiness decision authorizes, and before Project 03, which establishes the cabinet reference lines from the floor high point confirmed here.

Skills You Will Demonstrate

  • CB-001 — Inspect wall flatness, plumb, and finish condition across the cabinet installation area against the approved cabinet plan.
  • CB-002 — Inspect floor level, high point, and finish condition across the cabinet installation area against the approved finished-floor reference.
  • CB-003 — Locate wall studs, blocking, and backing across the full cabinet installation area using more than one verification method.
  • CB-004 — Identify plumbing, electrical, gas, and mechanical obstacles that affect cabinet layout, fastening, or continued service access.
  • CB-005 — Verify room dimensions and every scheduled cabinet, filler, panel, and appliance-opening dimension against the approved cabinet plan and cabinet schedule.
  • CB-006 — Document cabinet-installation readiness, including deficiencies and corrections, and issue an approved, conditional, or rejected readiness decision.

Where This Skill Fits

Every later project in this book depends on the survey completed here. The floor high point confirmed in this project controls the base-cabinet, countertop, and wall-cabinet reference lines established in Project 03, and the stud and service locations identified here control every structural fastener installed in Projects 4 through 6, 11, 14, 15, 16, 17, and 18. A wall or floor defect, an unmarked stud gap, or an unverified service location that is concealed rather than corrected here becomes a hidden fastening or access failure that Chapter 19 must trace back to its source during repair.

The document-review and readiness-decision method used here — reviewing controlling documents, inspecting before staging materials, separating conditions you may correct from conditions requiring another trade, and issuing a documented decision — is the same method used at the Chapter 20 capstone readiness checkpoint.

Scope and Intended Use

This project covers:

  • reviewing the current cabinet plan, interior elevations, cabinet schedule, appliance schedule, countertop plan, plumbing and electrical plans, and finish information
  • confirming finished-floor type, thickness, installation status, and reference elevation
  • inspecting walls for plumb, flatness, bow, humps, low spots, damaged drywall, moisture, and loose finishes
  • inspecting floors for level, high point, low point, deflection, damage, and transition conditions
  • inspecting ceilings and soffits where tall or wall cabinets approach them
  • verifying room dimensions, wall lengths, corners, openings, and ceiling height against the plan
  • measuring and verifying every cabinet width, height, depth, handing, filler, panel, and appliance-opening dimension
  • locating studs, blocking, backing, and structural support using more than one approved method
  • identifying plumbing supplies, drains, vents, shutoffs, cleanouts, appliance connections, receptacles, switches, junction boxes, disconnects, gas piping, ducts, and other service obstacles
  • confirming that required utilities will remain accessible after cabinet installation
  • inspecting door swings, window operation, passage clearances, and accessibility requirements
  • preparing a field-verified layout sketch and a deficiency list, reinspecting corrected items, and issuing a documented readiness decision

This project does not authorize the learner to:

  • select cabinet dimensions, cabinet quantities, appliance locations, or finish materials independently of the approved cabinet plan and schedules
  • cut, patch, relocate, or otherwise alter framing, drywall, flooring, plumbing, gas piping, or electrical components without an approved repair detail or the assigned licensed trade
  • conceal an active leak, mold, structural damage, damaged drywall, missing backing, unresolved framing defect, loose flooring, or inaccessible utility rather than mark it for correction or a qualified trade
  • proceed with work-area setup or cabinet layout before this project's readiness decision is issued and any required correction is complete

Any condition that does not match the approved plans, or that suggests active leaks, mold, structural damage, hazardous materials, or unsafe wiring, must stop work in that area until direction is obtained.

Reference Conventions

Establish these references before any inspection or measurement begins, and do not change them once the readiness decision has been issued.

Prerequisites

Common Field Fundamentals

Every readiness inspection in this book, from this chapter's wall-and-floor survey to the Chapter 20 capstone punch inspection, follows the same order: assemble and confirm the controlling documents, inspect the surface and structure across every accessible area, verify dimensions and conditions against the approved specification, locate concealed services, identify conditions outside your authority, correct or assign what is found, and issue a documented decision. Learning that sequence here protects every later inspection and installation project in this book.

Document reviewCabinet plan, schedules, and finished-floor status confirmed current
Wall and floor inspectionPlumb, flatness, level, high point, and finish condition checked
Service and dimension verificationStuds, backing, utilities, and every cabinet dimension confirmed
Decision and documentationDeficiencies corrected or assigned, and a readiness decision issued

Separating Conditions You May Correct From Conditions Requiring Another Trade

Every deficiency found in this project falls into one of two categories: a condition this project permits you to mark and carry forward as a documented layout note, or a condition requiring a plumber, electrician, structural professional, flooring installer, or other qualified trade. Marking a stud location, recording an out-of-level floor reading, or noting a wall bow within the cabinet plan's scribe allowance is within this project's authority. An active leak, damaged framing, an unsupported wall, or hazardous material is not; mark it, record it on the deficiency list, and obtain direction before continuing work in that area.

D. Acceptance Standards

CheckStandard
Wall conditionFree of bow, humps, low spots exceeding the cabinet plan's scribe allowance, damaged drywall, moisture, and loose finishes
Floor conditionHigh point identified and confirmed by repeated measurement; free of deflection, damage, and unresolved transition conditions within the cabinet footprint
Room and cabinet dimensionsWall lengths, corners, openings, and every scheduled cabinet, filler, panel, and appliance-opening dimension match the approved cabinet plan and schedule
Studs and backingLocated and marked across the full cabinet area using more than one verification method
Service locationsPlumbing, electrical, gas, and mechanical obstacles identified and confirmed to remain accessible after cabinet installation
Documentation completenessDeficiencies, corrections, the field-verified layout sketch, and the final readiness decision are recorded on the cabinet-installation readiness record

E. Document Review and Site Confirmation (Steps 1–2)

  1. Obtain the approved cabinet plan, interior elevations, cabinet schedule, appliance schedule, countertop plan, plumbing and electrical plans, and finish information. Confirm the revision date of each document against the project's document-control log before using it.
  2. Confirm finished-floor type, thickness, installation status, and reference elevation. Verify the flooring installation record shows the required completion before proceeding.

F. Wall, Floor, and Ceiling Inspection (Steps 3–6)

  1. Inspect walls for plumb, flatness, bow, humps, low spots, damaged drywall, moisture, and loose finishes. Use the 4-foot level and the 6-foot straightedge across each cabinet run, and probe suspect areas with the moisture meter.
  2. Inspect floors for level, high point, low point, deflection, damage, and transition conditions. Walk the full cabinet footprint and note any area with visible movement or damage.
  3. Inspect ceilings and soffits where tall or wall cabinets approach them. Confirm level, plumb, and clearance at each location a cabinet will contact the ceiling or soffit.
  4. Verify room dimensions, wall lengths, corners, openings, and ceiling height against the plan. Record each measurement directly on the field-verified layout sketch.

G. Dimensional and Service Verification (Steps 7–13)

  1. Measure and verify every cabinet width, height, depth, handing, filler, panel, and appliance-opening dimension. Compare each measurement against the approved cabinet schedule and appliance schedule.
  2. Locate studs, blocking, and backing. Mark each location directly on the wall with the marking pencil.
  3. Verify stud locations using more than one approved method where possible. Confirm stud-finder readings with a pilot-hole confirmation only where the wall finish and plan permit it.
  4. Identify plumbing supplies, drains, vents, shutoffs, cleanouts, and appliance connections. Compare each location with the plumbing plan and the cabinet schedule.
  5. Identify receptacles, switches, junction boxes, disconnects, lighting, and dedicated appliance circuits. Compare each location with the electrical plan and the appliance schedule.
  6. Identify gas piping, ducts, exhaust paths, radiators, baseboard heat, and other service obstacles. Mark each obstacle's location and clearance requirement on the layout sketch.
  7. Confirm that required utilities will remain accessible after cabinet installation. Compare each service location against the finished cabinet, filler, and panel positions shown on the plan.

H. Accessibility and Documentation (Steps 14–20)

  1. Inspect door swings, window operation, passage clearances, and accessibility requirements. Confirm each clearance against the approved plan and the applicable accessibility requirement.
  2. Identify conditions requiring shims, scribing, fillers, extended panels, backing, floor correction, or trade relocation. Mark each condition on the layout sketch and note the required correction.
  3. Stop work for active leaks, severe wall or floor defects, unsupported walls, hazardous materials, or conflicting services. Record the condition, the affected area, and the party contacted for direction.
  4. Prepare a field-verified layout sketch. Include room dimensions, floor high point, wall conditions, stud and backing locations, service locations, and cabinet-run boundaries.
  5. Prepare a deficiency list with location, responsible trade, required correction, and reinspection method. Include every condition marked in the prior steps, whether or not it has been corrected.
  6. Reinspect corrected items. Confirm each corrected condition against the Acceptance Standards table before considering it resolved.
  7. Issue an approved, conditional, or rejected cabinet-installation readiness decision. Base the decision on the completed deficiency list and the Acceptance Standards table, and identify the responsible party for any open item.

Performance Check

With document review, wall and floor inspection, ceiling and soffit inspection, dimensional verification, stud and service location, accessibility inspection, and correction or assignment complete, review the surveyed area against the Acceptance Standards table and confirm walls are plumb and flat within the scribe allowance, the floor high point is confirmed by repeated measurement, room and cabinet dimensions match the approved plan and schedules, studs and backing are located and marked, service locations are identified and confirmed accessible after installation, and every discrepancy has an assigned decision and responsible party. Complete and sign the cabinet-installation readiness record before the Project 02 work area is staged. If a discrepancy remains open, identify the responsible party and required decision before proceeding.

Project Closeout

You have completed the first project in the cabinet-installation sequence: inspecting walls, floors, and layout conditions for cabinet installation. This project required you to inspect wall flatness and plumb (CB-001), inspect floor level and high point (CB-002), locate studs and backing using more than one method (CB-003), identify plumbing, electrical, gas, and mechanical obstacles (CB-004), verify room and cabinet dimensions against the approved plan and schedule (CB-005), and document cabinet-installation readiness with a supported decision (CB-006).

You now have a field-verified installation-area survey with a signed cabinet-installation readiness record. That decision carries directly into the next project: setting up a protected, organized cabinet-unpacking, staging, cutting, lifting, and assembly work area within the area accepted here.

Protect the confirmed floor high point, marked stud and backing locations, and identified service locations established in this project. Project 03 establishes every cabinet reference line from the floor high point confirmed here.
