Job Overview

This chapter qualifies you to inspect a proposed masonry project and produce a documented masonry-readiness plan. The finished work product is one completed Masonry-Readiness Worksheet covering project classification, base and support condition, drainage and moisture exposure, wall condition, openings and reinforcement, access and staging, utility and flue conflicts, a stop-work determination where applicable, material identification, weather controls, a preliminary quantity and crew plan, a deficiency list, a reinspection record, and a final readiness decision.

You will select one proposed masonry project — block, brick, stone, veneer, repair, chimney-exterior-maintenance, or small nonretaining wall — and inspect it in the field before any masonry unit, mortar, or tool is staged. Nothing in this chapter authorizes you to lay masonry, mix mortar, cut units, or perform chimney, flue, or structural work; this chapter produces the planning document that later chapters and later projects depend on.

This is the first chapter in the book. Every later chapter in this book — mixing mortar, laying out a wall, building block or brick, installing veneer and flashing, repairing masonry, building a garden wall or steps, inspecting a chimney, cleaning and sealing, and the Chapter 20 capstone — depends on a completed, accurate readiness plan for the selected project.

Skills You Will Demonstrate

  • RM-001 — Identify masonry project type, classifying it as load-bearing, nonload-bearing, veneer, freestanding, retaining, repair, chimney-related, step-related, or decorative.
  • RM-002 — Inspect substrate or base conditions, including footing, slab, shelf angle, ledge, framing, sheathing, or existing masonry support.
  • RM-003 — Evaluate drainage needs, including grade, roof runoff, splashback, cap details, flashing, weeps, foundation drainage, and freeze-thaw exposure.
  • RM-004 — Identify structural concerns, including wall displacement, bulging, cracking, failed joints, spalls, failed lintels, and loose chimney sections.
  • RM-005 — Select masonry materials, identifying units, mortar, grout, reinforcement, ties, flashing, weeps, sealants, cleaners, and caps specified for the project.
  • RM-006 — Document project readiness, issuing an approved, conditional, or rejected masonry-readiness decision supported by a written deficiency list and inspection record.

Where This Skill Fits

Every project in this book begins the same way: with an inspection of what already exists before a single masonry unit is staged. The readiness plan you produce here defines the base condition, drainage strategy, and material list that Chapter 2 uses to stage the work area, that Chapter 3 uses to select mortar, and that Chapter 4 uses to lay out the wall.

The stop-work determination you practice in this chapter — recognizing settlement, structural movement, unidentified flues, and unsafe access before work begins — is the same judgment used throughout the book, including in the Chapter 18 chimney inspection and the Chapter 20 capstone.

Scope and Intended Use

This chapter covers:

  • classifying a proposed masonry project by structural role and work type
  • inspecting an existing base, footing, slab, shelf angle, ledge, or support for level, width, cracks, settlement, contamination, moisture, and bearing
  • inspecting surrounding grade, drainage, and moisture sources
  • inspecting existing masonry, where present, for alignment, bulging, displacement, cracking, failed joints, spalls, staining, and prior repairs
  • identifying openings, lintels, ties, anchors, reinforcement, movement joints, and service or roof interfaces from approved drawings and visual inspection
  • inspecting access, delivery routes, scaffold conditions, mixing area, washout, and weather exposure
  • identifying utility, flue, and structural conflicts
  • identifying masonry units, mortar, grout, reinforcement, ties, flashing, weeps, sealants, cleaners, and caps specified for the project
  • preparing a preliminary quantity, staging, crew, access, and protection plan
  • preparing a deficiency list, reinspecting corrected items, and issuing a readiness decision

This chapter does not authorize the learner to:

  • lay masonry units, mix or place mortar or grout, cut masonry, or install veneer, flashing, or reinforcement; those tasks belong to later chapters
  • proceed on any retaining wall, load-bearing wall, foundation wall, reinforced masonry, tall freestanding wall, chimney, fireplace, structural pier, or major veneer system without the exact engineered design and inspection sequence supplied by a qualified professional
  • alter chimney flues, liners, smoke chambers, fireplaces, dampers, combustion-air systems, vent connectors, or gas appliances under this chapter
  • disturb, remove, or repair any masonry, flashing, or structural element discovered to be unstable, displaced, or actively moving; such conditions are documented and referred, not corrected, in this chapter

Any base, support, wall, or chimney condition that fails the inspection in this chapter must be documented, corrected by a qualified party where required, and reinspected before masonry work begins.

Reference Conventions

Establish these references before any inspection finding is recorded, and use them consistently across the worksheet.

TermDefinition
Project typeThe single controlling classification recorded in Step 2 — load-bearing, nonload-bearing, veneer, freestanding, retaining, repair, chimney-related, step-related, or decorative
Base or supportThe footing, slab, shelf angle, ledge, framing, sheathing, or existing masonry the new or repaired work will bear on
DeficiencyAny inspected condition that does not meet the acceptance standards in this chapter and must be corrected or referred before work proceeds
Stop-work conditionA deficiency listed in the Acceptance Standards table that halts the inspection for that item until a qualified professional evaluates it
Readiness decisionThe single final classification recorded in Step 19 — Approved, Conditional, or Rejected — for the project as a whole

Project Identification Record

Before beginning the inspection, record the selected project and its controlling documents directly on the Masonry-Readiness Worksheet:

Project name: ______     Project type: ______ (load-bearing / nonload-bearing / veneer / freestanding / retaining / repair / chimney-related / step-related / decorative)

Approved drawings on hand: ______ (Y/N)     Permit required: ______ (Y/N/Unknown)     Responsible design/inspection authority: ____________

Date inspected: ____________     Inspector name: ____________

Prerequisites

Common Field Fundamentals

Every project in this book, from a small garden wall to the Chapter 20 capstone, depends on the same sequence taught here: classify the project, inspect the base, evaluate drainage, check for structural concerns, identify the specified materials, and document a readiness decision before any masonry is staged. Learning that sequence here, on a single proposed project, means every later chapter starts from a plan you already trust.

ClassificationOne controlling project type recorded before inspection begins
Base & supportLevel, width, cracks, settlement, contamination, moisture, bearing
Drainage & moistureGrade, roof runoff, splashback, flashing, weeps, freeze-thaw exposure
Structural conditionAlignment, bulging, displacement, cracking, failed joints, spalls
MaterialsUnits, mortar, grout, reinforcement, ties, flashing, weeps, sealants, caps
Access & stagingDelivery routes, scaffold conditions, mixing area, washout, weather exposure
ConflictsElectrical, gas, plumbing, drainage, flue, and structural conflicts
Readiness decisionOne final classification: Approved, Conditional, or Rejected

Project Classification and Stop-Work Judgment

The project-type classification recorded in Step 2 controls how the rest of the inspection is read. A retaining wall, load-bearing wall, foundation wall, reinforced masonry, tall freestanding wall, chimney, fireplace, structural pier, or major veneer system is never treated as ordinary practice work in this book unless the exact engineered design and inspection sequence are supplied. Record the classification before evaluating any other item, and do not change it later to make a deficient condition appear less serious.

C. Documentation Requirements

  • Photographs: at least one photograph of the base or support, the surrounding grade and drainage, any existing masonry condition, and every recorded deficiency.
  • Drawing references: a citation to the specific drawing sheet, detail, or specification section supporting every material and dimension identified in Step 13 and Step 14.
  • Deficiency list: a written list of every item recorded as Deficient or Stop-Work, with location, description, and required correction or referral.
  • Reinspection record: the date, method, and result of reinspecting every corrected deficiency before the readiness decision is finalized.

D. Acceptance Standards

CheckStandard
Base levelLevel within the tolerance stated in the approved drawings; if none is stated, record the measured out-of-level condition and refer it rather than estimating a tolerance
Base cracking, settlement, contaminationNone present; any found condition is recorded as Deficient or Stop-Work per the classification below
DrainageGrade slopes away from the base and no unmanaged roof runoff, splashback, or standing water is present at the work area
Existing wall conditionNo bulging, displacement, widespread cracking, failed lintels, or loose chimney sections; isolated hairline mortar cracking is recorded as Deficient and referred to Chapter 14 or Chapter 15 scope, not corrected here
Stop-work conditionsUnstable foundations, active settlement, major wall displacement, bulging walls, failed lintels, widespread cracking, loose chimney sections, fire damage, unidentified flue conditions, or movement requiring structural evaluation; inspection of that item stops and is referred to a qualified professional
Materials identifiedEvery masonry unit, mortar, grout, reinforcement, tie, flashing, weep, sealant, cleaner, and cap is traced to a specific approved drawing, specification, or manufacturer instruction; no material is selected by the inspector without a controlling document
Readiness decisionApproved: no deficiencies recorded. Conditional: deficiencies recorded but correctable without professional redesign, with every item reinspected and cleared before Chapter 2 begins. Rejected: one or more stop-work conditions present; the project does not proceed until a qualified professional resolves them and a new inspection is performed

E. Preparation — Documents and Project Selection

  1. Obtain approved drawings, site information, wall sections, foundation or ledge details, drainage details, material specifications, and permit requirements. Confirm every document is the current approved version before the inspection begins.
  2. Define whether the project is load-bearing, nonload-bearing, veneer, freestanding, retaining, repair, chimney-related, step-related, or decorative. Record this classification on the Project Identification Record before proceeding.
  3. Identify the responsible design and inspection authority. Record the name and contact information of the engineer, architect, building department, or other authority of record for the project.

F. Base, Support, and Drainage Inspection

  1. Inspect the base, footing, slab, shelf angle, ledge, framing, sheathing, or existing masonry support. Identify the exact support element the new or repaired work will bear on.
  2. Check support for level, width, cracks, settlement, contamination, moisture, and adequate bearing. Use the level, tape measure, and moisture meter and record every reading on the Inspection Item Schedule.
  3. Inspect surrounding grade and drainage. Confirm the grade slopes away from the work area and record any standing water, ponding, or reversed slope.
  4. Identify water sources, roof runoff, splashback, cap details, flashing, weeps, foundation drainage, and freeze-thaw exposure. Record the location of every identified water source relative to the proposed work.

G. Existing Masonry, Openings, and Conflict Inspection

  1. Inspect wall alignment, bulging, displacement, cracking, failed joints, spalls, staining, and previous repairs. Photograph every condition found and record it as Pass, Deficient, or Stop-Work.
  2. Identify openings, lintels, ties, anchors, reinforcement, movement joints, service penetrations, and roof or wall interfaces. Cross-reference each against the approved drawings.
  3. Inspect access, material-delivery routes, scaffold conditions, lifting needs, mixing area, washout, and weather exposure. Record measured clearances for delivery and staging areas.
  4. Identify electrical, gas, plumbing, drainage, flue, and structural conflicts. Mark the location of every identified conflict on the site sketch or drawing.
  5. Stop work for disputed support, unidentified flues, major structural cracking, active movement, loose chimneys, failed lintels, or unsafe access. Classify each stopped item per the Acceptance Standards table and record the required professional referral.

H. Materials, Weather Controls, and Preliminary Planning

  1. Identify masonry units, mortar, grout, reinforcement, ties, flashing, weeps, sealants, cleaners, and caps specified for the project. Cite the specific drawing, specification section, or manufacturer instruction for each.
  2. Verify unit dimensions, absorption, finish, color range, and compatibility. Record each value with its source document.
  3. Determine cold-, hot-, wet-, and windy-weather controls. Record the specific protection method required for the anticipated construction season.
  4. Prepare a preliminary quantity, staging, crew, access, and protection plan. Base every quantity on the component schedule in the approved drawings; do not estimate quantities without a source document.

I. Deficiency Resolution and Readiness Decision

  1. Prepare a deficiency and prerequisite list. Compile every item recorded as Deficient or Stop-Work into a single written list with location, description, and required correction or referral.
  2. Reinspect corrected items. Return to each corrected deficiency, verify the correction using the same tool or method used in the original inspection, and record the reinspection date and result.
  3. Issue an approved, conditional, or rejected masonry-readiness decision. Base the decision solely on the Acceptance Standards table; a project with any unresolved stop-work condition must be classified Rejected.
  4. Document professional referrals and inspection hold points. Record every professional referral made during the inspection and every hold point that must be cleared before the corresponding later chapter begins.

Common Readiness Inspection

Inspect every readiness plan using the same checks regardless of the selected project type.

Skill Check

  1. Why must the project-type classification be recorded before the base inspection begins, rather than after all findings are known?
  2. What is the difference between a Deficient finding and a Stop-Work condition, and give two examples of each?
  3. What must the inspector do, and not do, when a wall or chimney section shows major displacement or widespread cracking?
  4. Why must every identified masonry material be traced to a specific drawing, specification, or manufacturer instruction rather than selected from general trade practice?
  5. What are the three possible readiness decisions, and what recorded conditions require each one?
  6. Why must corrected deficiencies be reinspected using the same tool or method as the original inspection?
  7. What access, staging, and drainage conditions must be inspected in addition to the base and wall itself?
  8. What must the learner do before a project with an unresolved stop-work condition is allowed to proceed to Chapter 2?
  9. Why does this chapter prohibit reconstructing inspection findings from memory after leaving the site?
  10. What professional referrals might this chapter require, and why does completing this chapter not authorize the learner to perform that professional's work?

Performance Check

With the site inspection complete, review the Masonry-Readiness Worksheet against the Acceptance Standards table and confirm every base, drainage, structural, opening, access, conflict, and material item has been recorded with a measurement, photograph, or source-document citation. Confirm every Deficient item has a documented correction and reinspection record, and every Stop-Work item has a documented professional referral. Issue the final readiness decision only after every deficiency has been reinspected and cleared or referred. A project classified Rejected does not proceed to Chapter 2 until the referred conditions are resolved and a new inspection is performed.

Project Closeout

You have completed the first chapter in the residential masonry sequence: inspecting and planning a masonry project. This chapter required you to identify masonry project type (RM-001), inspect substrate or base conditions (RM-002), evaluate drainage needs (RM-003), identify structural concerns (RM-004), select masonry materials (RM-005), and document project readiness (RM-006).

You now have a completed Masonry-Readiness Worksheet identifying the project's base, drainage, structural condition, materials, access, hazards, permits, inspections, and prerequisites. That worksheet carries directly into the next chapter: setting up a controlled masonry work area and material staging plan based on the exact quantities, access conditions, and weather controls you documented here.

File your completed Masonry-Readiness Worksheet, photographs, and referral records with the approved drawings for this project. You will reference this exact readiness plan throughout the rest of this book.
