Masonry specs name specific unit manufacturers, mortar producers, and accessory suppliers. Look for: - CMU manufacturer substitutions (Oldcastle/CRH, Basalite, Angelus Block, Trenwyth, QUIKRETE) - Brick manufacturer substitutions (Boral, General Shale, Acme Brick, Glen-Gery, Endicott) - Natural stone supplier changes (quarry source matters for color and physical properties) - Cast stone manufacturer substitutions (Arriscraft, Indiana Limestone, US Precast) - Mortar manufacturer substitutions (Spec Mix, Quikrete, Lehigh Hanson, US Mix) - Masonry accessory substitutions for ties, anchors, flashing (Hohmann & Barnard, Wire-Bond, Blok-Lok, Heckmann) - Through-wall flashing manufacturer changes (Sandell, Mortar Net, Hohmann & Barnard) - Masonry sealer/repellent manufacturer changes (Prosoco, Sikagard, Sto) Full guide: https://deviationcheck.com/divisions/04-masonry/manufacturer-substitution/ ### Performance Specification Gap (default grade: Blocker) A measurable performance property in the submittal (rating, capacity, tolerance, efficiency) does not meet what the spec requires. Key performance parameters in masonry submittals: - **CMU compressive strength** (f'm prism strength, unit strength per ASTM C90: typically 1900-3000 psi for load-bearing) - **CMU weight class** (normal weight ~135 pcf, medium weight ~105-125 pcf, lightweight ~85-105 pcf) - **CMU moisture content** (Type I moisture-controlled vs Type II non-moisture-controlled) - **Brick compressive strength** (psi per ASTM C62, C216, or C652) - **Brick absorption rate** (% per ASTM C67, affects bond and freeze-thaw durability) - **Brick grade** (SW Severe Weathering, MW Moderate Weathering per ASTM C62/C216) - **Mortar type** (M, S, N, O per ASTM C270 - property vs proportion specification) - **Grout strength** (f'g psi at 28 days per ASTM C476) - **Reinforcing steel grade** (Grade 60 per ASTM A615/A706) - **Stone flexural strength** (modulus of rupture per ASTM C99/C880) - **Stone absorption rate** (% per ASTM C97) - **Fire rating** of masonry assembly (hours per UL/WHI listing or calculated per TMS 216) - **STC rating** of masonry assembly - **Thermal resistance** (R-value of insulated masonry assembly) Full guide: https://deviationcheck.com/divisions/04-masonry/performance-specification-gap/ ### Missing Certification or Compliance Documentation (default grade: Fix and Resubmit) A required listing, test report, certification, or compliance document is absent from the submittal package. Required certifications in masonry submittals: - **TMS 402/602** compliance (Building Code Requirements and Specification for Masonry Structures) - **ASTM C90** test reports for concrete masonry units (compressive strength, absorption, moisture content) - **ASTM C62/C216/C652** test reports for brick (compressive strength, absorption, saturation coefficient, IRA) - **ASTM C270** mortar compliance (property or proportion method) - **ASTM C476** grout compliance - **ASTM C1019** grout prism test reports - **Mill certificates** for masonry reinforcing steel - **Fire resistance documentation** (UL assembly listing or TMS 216.1 calculated rating) - **Seismic compliance** documentation (IBC/ASCE 7, TMS 402 seismic provisions) - **ASTM C97/C99/C170/C880** test reports for natural stone (absorption, flexural, compressive) - **LEED documentation** (recycled content for CMU, regional materials) - **Efflorescence test results** (ASTM C67 for brick, ASTM C1372 for CMU) Full guide: https://deviationcheck.com/divisions/04-masonry/missing-certification/ ### Aesthetic Deviation (default grade: Fix and Resubmit) A visible attribute (color, finish, texture, profile) differs from the spec or the architect-approved sample. - CMU color, texture, and surface finish (smooth, split-face, scored, ground-face, burnished, fluted) - Brick color, texture, size, and coursing pattern (running bond, stack bond, Flemish bond) - Natural stone color, finish (polished, honed, thermal/flamed, bush-hammered, sandblasted), and veining - Cast stone color match to natural stone - Mortar joint color (natural, colored to match/contrast) - Mortar joint profile (concave, V-joint, raked, weathered, flush) - Control joint and expansion joint sealant color Full guide: https://deviationcheck.com/divisions/04-masonry/aesthetic-deviation/ ### Detail or Installation Mismatch (default grade: Fix and Resubmit) The submitted detail, dimension, anchorage, or installation method differs from what the spec or drawings require. - **Bond pattern** differs from drawings (running bond vs stack bond vs other) - **Mortar joint thickness** differs from spec (typically 3/8" for CMU, 3/8" for brick) - **Reinforcing bar size or spacing** differs from structural drawings - **Grout pour height** or lift height exceeds TMS 602 limits - **Wall tie type or spacing** differs (adjustable vs non-adjustable, horizontal/vertical spacing) - **Through-wall flashing** type or termination detail differs - **Weep hole spacing** or type differs (open head joint, wicks, tubes) - **Control joint spacing** differs from spec or structural drawings - **Expansion joint location** differs (critical for brick to accommodate thermal movement) - **Lintel size or bearing length** differs from structural design - **Shelf angle location or size** differs - **Veneer anchor type or embedment** differs Full guide: https://deviationcheck.com/divisions/04-masonry/detail-installation-mismatch/ ### Submittal Package Incompleteness (default grade: Fix and Resubmit) A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. Commonly required items in Div 04 specs: - CMU product data with ASTM C90 test results - Brick samples and product data with ASTM C216 test results - Natural stone samples with ASTM test results (C97, C99, C170, C880) - Mortar mix design or product data per ASTM C270 - Grout mix design per ASTM C476 - Masonry reinforcing steel mill certificates - Wall tie and anchor product data with pull-out test results - Through-wall flashing product data and installation details - Shop drawings for reinforced masonry (bar placement, grouting plan) - Stone cladding shop drawings with anchorage details - Cast stone shop drawings with joint layout - Masonry prism test plan (f'm testing per ASTM C1314) - Sealer/repellent product data and mock-up plan - Cold weather and hot weather masonry plan --- Full guide: https://deviationcheck.com/divisions/04-masonry/submittal-package-incompleteness/ ## How Division 04 deviations are graded - **CMU compressive strength below spec f'm:** BLOCKER (structural capacity per TMS 402) - **Brick grade below weathering requirement (MW where SW specified):** BLOCKER (freeze-thaw durability) - **Mortar type below spec (Type N where Type S specified):** BLOCKER (structural capacity and weather resistance) - **Grout strength below spec:** BLOCKER (structural capacity for reinforced masonry) - **Reinforcing grade below spec:** BLOCKER (structural per TMS 402) - **Missing fire rating documentation for rated assembly:** BLOCKER (life-safety) - **Missing seismic compliance for reinforced masonry:** BLOCKER (IBC) - **Wall tie type or spacing non-compliant with TMS 402:** BLOCKER (structural connection of wythes) - **Through-wall flashing omitted where spec requires:** BLOCKER (water infiltration, structural damage) - **CMU weight class mismatch (lightweight where normal weight specified for structural):** BLOCKER if structural, FIX_AND_RESUBMIT if non-structural - **Brick color or texture mismatch:** FIX_AND_RESUBMIT (aesthetic) - **Mortar joint profile mismatch:** FIX_AND_RESUBMIT (aesthetic) - **Missing efflorescence test results:** FIX_AND_RESUBMIT (quality assurance)
