CMU appears on architectural plans, structural sheets, wall type schedules, specs, and sections, each slice must tell the same story about rating, reinforcement, coursing, openings, and lintels.
Precast units laid in mortar, not the same as cast-in-place concrete. Document symbology (hatch patterns, tags) must stay consistent across disciplines.
Understand hollow vs solid vs grouted cells, bond beams, lintels, knockouts, coursing, control joints, and wall ties. Low-lift vs high-lift grouting and joint tooling affect weathering and inspection paths.
Load-bearing, shear, fire-rated assemblies, shafts, retaining conditions, each carries different schedule reinforcement and connection requirements per ACI 530 and project geotech when retaining.
Cross-reference CMU schedules, sections, and structural plans for the mismatch patterns above inside a full plan review or structural sweep before permit or bid.
Nominal 8x8x16 is most common; verify actual vs nominal for coursing math.
Units+mortar vs monolithic cast placement, different details and specs.
Depends on design, structural sheets and schedules govern reinforcement.
Concrete masonry unit.
