Safety Cue
Task-specific safety guidance for ordinary capstone hazards.
Chapter 20 — Capstone
Plan, lay out, build, protect, inspect, document, and close out either a complete drained masonry-veneer practice section or a small nonretaining garden-wall section, integrating base preparation, mortar mixing, unit placement, cutting, reinforcement or ties, flashing and weeps, joint tooling, cleaning, and final inspection into one closed-out project.
These cues appear at the point of work. They identify safety, code, manufacturer, and measurement issues before they become rework, structural risk, or moisture damage.
Task-specific safety guidance for ordinary capstone hazards.
Serious injury, structural failure, or major damage is possible.
Practical work-area safety: access, footing, lighting, and housekeeping.
Local requirements vary. Verify permit, inspection, and jurisdictional rules.
Follow product-specific instructions for units, mortar, ties, and flashing.
Clearance, layout, drainage, and reference-point guidance.
This capstone chapter integrates every competency taught in Chapters 1 through 19 into one closed-out masonry section. The finished work product is one complete, cured, drained, aligned, and documented masonry veneer practice section or nonretaining garden-wall section, selected under the Capstone Continuity Rule established in the book outline.
You will select one approved capstone option — a drained masonry-veneer practice section built on an approved practice foundation, engineered veneer practice wall, or slab section completed through Book 16, or a small nonretaining garden-wall section built on an approved footing — and carry it through readiness inspection, work-area staging, material inventory, layout, base preparation, water-management installation where applicable, mortar mixing, unit placement, cutting, reinforcement or tie placement, joint tooling, cleaning, curing, final inspection, and closeout.
This is the last chapter in Book 17. Nothing in this chapter introduces a new structural design, a new water-management detail, or a new material not already specified by the approved capstone documents identified in Step 2. This chapter does not authorize retaining-wall, load-bearing, chimney, fireplace, or structural-pier work beyond what has already been taught and approved in earlier chapters.
Every chapter in this book contributed one piece of the sequence this chapter now integrates: Chapter 1 readiness inspection, Chapter 2 work-area staging, Chapter 3 mortar mixing, Chapter 4 layout, Chapters 5 through 7 block laying and reinforcement, Chapters 8 through 10 brick laying and cutting, Chapters 11 through 13 veneer and water management, Chapters 14 and 15 repair judgment, Chapters 16 and 17 garden-wall and step geometry, Chapter 18 chimney inspection boundaries, and Chapter 19 cleaning and sealing.
The completed, documented section produced in this chapter is handed off directly to Book 18 for hardscaping coordination. The support, drainage, reinforcement or tie design, movement strategy, and inspection sequence you document here become the starting condition for that later work.
This chapter covers:
This chapter does not authorize the learner to:
Any base, support, or prior condition that fails the readiness inspection in this chapter must be documented, corrected by a qualified party where required, and reinspected before capstone work begins.
Establish these references before capstone work begins, and use them consistently across every record produced in this chapter.
| Term | Definition |
|---|---|
| Capstone option | The single selected project recorded in Step 1 — drained masonry-veneer practice section or small nonretaining garden-wall section |
| Controlling documents | The complete support, drainage, reinforcement or tie, flashing, joint, finish, weather, permit, and inspection documents obtained in Step 2 for the selected option |
| Hold point | An inspection step that must pass before the next phase of work may begin, including base acceptance, pre-lay inspection, pre-grout or pre-cavity-closure inspection, and final inspection |
| Deficiency | Any inspected condition that does not meet the acceptance standards in this chapter and must be corrected or referred before closeout |
| Closeout package | The compiled layout, batch, mortar, grout, reinforcement, tie, flashing, weep, weather, cleaning, photograph, and inspection record handed off at the end of this chapter |
Before beginning the capstone project, record the selected option and its controlling documents directly on the closeout binder cover sheet:
Capstone option: ______ (Drained veneer practice section / Small nonretaining garden-wall section)
Base source: ______ (Approved practice foundation or slab section completed through Book 16 / Engineered veneer practice wall / Nonstructural garden-wall practice base)
Controlling documents on hand: ______ (Y/N) Responsible design/inspection authority: ____________
Date started: ____________ Learner name: ____________
The capstone project follows the same support-to-closeout sequence established in the book outline's System-Sequence Control: base, drainage, movement, structural role, and weather exposure are resolved before mortar or units are staged; layout, corners, leads, story poles, course heights, openings, reinforcement, flashing, and joints are established before production wall work; reinforcement, ties, lintels, flashing, and grout or cavity spaces are inspected before concealment; and cleaning follows sufficient cure using the least aggressive compatible method.
The capstone option recorded in Step 1 controls every later step in this chapter. Do not mix the component schedule, reinforcement design, or water-management system of one option with the other. A veneer practice section and a garden-wall section are built, inspected, and closed out using separate sequences within this chapter, and the learner completes one option, not a combination of both, unless the book outline for a specific program explicitly authorizes both.
Build a new story pole for the capstone section using the actual unit height and specified bed-joint thickness for the selected option's units. Do not reuse a story pole built for a different chapter's practice wall, even if the unit type appears similar.
Do not begin base preparation or mortar mixing if the reissued Chapter 1 readiness decision for this capstone project is Rejected, or if any stop-work condition identified in that inspection remains unresolved. Stop work immediately if settlement, active movement, or an unidentified structural condition appears in the practice foundation or base during capstone work, and refer it to the responsible design or inspection authority.
Because this project spans multiple working days, protect uncured mortar, exposed reinforcement, open cavities, and unfinished flashing at the end of every work session using the specified covers, and reinspect protection at the start of the next session before resuming work.
Confirm the professional design and inspection responsibilities identified in Step 3 before proceeding. Even a practice-scale capstone section follows the reinforcement, flashing, and inspection requirements of its controlling documents; a project labeled "practice" does not exempt it from the acceptance standards in this chapter.

Capstone / Integrated Construction / Documentation
Deliverable: one completed capstone masonry section — drained veneer practice section or small nonretaining garden-wall section — built to the exact support, drainage, reinforcement or tie, flashing, joint, and finish requirements of its approved controlling documents, inspected at every hold point, cleaned, cured, and handed off with a complete closeout package.
| Component | Quantity | Material | Finished Size | Preparation |
|---|---|---|---|---|
| Veneer units | Per approved drawing takeoff | Brick or stone veneer unit specified in the controlling documents | As specified; cut units per Chapter 10 | Cleaned of mud, ice, and loose material before laying |
| WRB and flashing | Per elevation and opening count | Weather-resistive barrier, base and through-wall flashing as specified | Shingle-lap sequence with end dams | Inspected for continuity before veneer placement |
| Wall ties | Per specified spacing | Corrosion-resistant ties listed in the controlling documents | As specified | Installed at marked rows with correct embedment and slope |
| Weeps | Per specified spacing | Open-head, tube, wick, or proprietary weep specified | As specified | Aligned with flashing; kept free of mortar |
| Mortar | Per batch schedule | Type specified for the veneer unit and exposure | N/A | Mixed per Chapter 3 |
| Component | Quantity | Material | Finished Size | Preparation |
|---|---|---|---|---|
| Wall units | Per approved drawing takeoff | Block, brick, or stone unit specified in the controlling documents | As specified; cut units per Chapter 10 | Cleaned of mud, ice, and loose material before laying |
| Footing or base | 1 | Compacted aggregate or concrete footing specified in the controlling documents | As specified width, depth, and elevation | Compacted, leveled, and inspected before laying |
| Reinforcement or connectors | Per specified schedule, if any | Only the reinforcement, pins, adhesive, or connectors named in the controlling documents | As specified | Installed only at the specified stage |
| Cap units | Per wall length | Cap unit specified with slope and drip detail | As specified | Set with adhesive or mortar per the controlling documents |
| Mortar | Per batch schedule | Type specified for the wall unit and exposure | N/A | Mixed per Chapter 3 |
Base every quantity, tie spacing, weep spacing, reinforcement schedule, and fastener specification on the approved controlling documents identified in Step 2. Do not estimate a quantity, spacing, or fastener size that is not stated in those documents; where a value is missing, record it as a deficiency under Step 36 rather than selecting one independently.
| Hold Point | Standard |
|---|---|
| Readiness inspection (Chapter 1) | Reissued Approved or Conditional decision for this specific capstone project before staging begins |
| Base or footing acceptance | Level, width, and bearing within the tolerance stated in the controlling documents; no cracking, settlement, or contamination |
| Pre-lay inspection | Layout, story pole, course marks, and mason's line verified against the controlling documents before the first course is laid |
| Pre-concealment inspection (veneer option) | WRB continuity, flashing laps and end dams, cavity cleanliness, tie spacing and embedment, and weep alignment verified and photographed before veneer coursing conceals them |
| Pre-concealment inspection (garden-wall option) | Reinforcement, connectors, and footing condition verified and photographed before any specified grout, adhesive, or backfill conceals them |
| Bond, joints, and alignment | Specified bond maintained; full bed and head joints; wall plumb and level within the tolerance stated in the controlling documents |
| Cutting | All cuts performed per Chapter 10 wet-cutting or extraction controls; no dry-cut units where the silica-control plan requires wet cutting |
| Final inspection | Support, line, level, plumb, bond, joint fullness, tooling, cuts, reinforcement or ties, flashing, weeps, cavity or drainage condition, and cap all verified with no unresolved deficiency |
| Closeout | Complete compiled record set produced and the section formally handed off for Book 18 hardscaping coordination |
Inspect every completed capstone section using the same checks regardless of the selected option.
Complete the Capstone Closeout Checklist in the Inspection Checklist section below before this project, and this book, are considered closed out.
Probable cause: laying continued past the pre-concealment hold point without stopping for inspection and photographs.
Confirmation: compare the closeout package against the Section D hold-point list; a missing pre-concealment photograph or inspection record confirms the condition.
Correction: where physically possible, expose the concealed detail for inspection and photography; where exposure would damage the completed work, document the omission as an unresolved deficiency and obtain professional evaluation before final closeout.
Reinspection: repeat the affected hold-point inspection and update the closeout package.
Probable cause: a reinforcement, tie, or water-management detail from the unselected option was installed alongside the selected option's components.
Confirmation: compare the as-built section against the Component Schedule for the selected option only.
Correction: remove or correct the mismatched component so the section matches a single option's controlling documents.
Reinspection: repeat the affected placement and pre-concealment inspections.
Probable cause: an existing story pole or layout mark was reused without verifying unit height and joint thickness for this specific capstone project.
Confirmation: measure actual course heights against the reused story pole; a mismatch confirms the condition.
Correction: build a new story pole using the actual units and specified joint thickness for this project and remark course elevations.
Reinspection: repeat the pre-lay layout inspection using the corrected story pole.
Probable cause: a corrected item was marked resolved based on visual impression rather than repeating the original inspection tool or method.
Confirmation: compare the deficiency list's correction entries against reinspection dates and methods; a missing reinspection date confirms the condition.
Correction: reinspect every corrected item using the same tool or method as the original inspection before closeout.
Reinspection: record the completed reinspection date and result for each item.
Probable cause: a sealer was applied in Step 39 before the underlying flashing, drainage, or structural deficiency identified in the final inspection was corrected.
Confirmation: compare the deficiency list against the sealer application date; a sealer applied before a related deficiency's reinspection date confirms the condition.
Correction: remove the sealer if compatible removal is possible, correct the underlying deficiency, reinspect, and reapply sealer only if it remains specifically approved.
Reinspection: confirm the underlying deficiency passes reinspection before any sealer is reapplied.
This chapter, and this book, end with a completed, filed closeout package, not a verbal impression of the finished section.

With the capstone section complete, review the Capstone Closeout Checklist against the Acceptance Standards and Hold Points table and confirm every base, layout, placement, cutting, concealed-detail, cleaning, and final-inspection item has been recorded with a measurement, photograph, or inspection reference. Confirm every deficiency has a documented correction and reinspection record. Compile the closeout package only after every hold point has passed and hand it off for Book 18 hardscaping coordination.
You have completed the final chapter in the residential masonry sequence: the capstone integration of layout, base preparation, mortar mixing, unit placement, cutting, reinforcement or ties, flashing and weeps, joint tooling, cleaning, final inspection, and masonry closeout. This chapter required you to integrate layout (RM-115), integrate base preparation, mortar mixing, and unit placement (RM-116), integrate cutting, reinforcement or ties, and flashing and weeps (RM-117), integrate joint tooling and cleaning (RM-118), perform final inspection (RM-119), and complete masonry closeout (RM-120).
You now have one complete, cured, drained, aligned, and documented masonry veneer or nonretaining garden-wall section, with every base, drainage, reinforcement or tie, flashing, weep, joint, and cleaning decision traced to its controlling document and inspection record. This completed section, together with its closeout package, is handed off directly to Book 18 for hardscaping coordination.
File your completed closeout package, photographs, and referral records with the approved capstone documents for this project. This package is the starting condition for every Book 18 hardscaping project built around this section.
