Concrete specs frequently name specific ready-mix producers, precast fabricators, and specialty product manufacturers. Look for: - Ready-mix producer substitutions (CalPortland, CEMEX, Lehigh Hanson, Martin Marietta, Vulcan Materials) - Precast manufacturer substitutions (Clark Pacific, Coreslab Structures, Gate Precast, Metromont, Oldcastle) - Reinforcing steel fabricator changes - Admixture manufacturer substitutions (BASF/Master Builders, GCP Applied Technologies, Sika, Euclid Chemical) - Fiber reinforcement brand changes (Fibermesh, Forta, Nycon) - Formwork system substitutions (Doka, PERI, EFCO, Symons) - Curing compound and sealer manufacturer changes Full guide: https://deviationcheck.com/divisions/03-concrete/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 concrete submittals: - **Compressive strength (f'c)** in psi at 28 days (most common: 3000, 4000, 5000, 6000 psi) - **Slump** range in inches (typical 4-6 inches for conventional, higher for SCC) - **Air content** percentage (4-7% for freeze-thaw exposure per ACI 318) - **Water-to-cementite ratio (w/cm)** maximum per exposure class - **Chloride ion content** limit for reinforced concrete (ACI 318 Table 19.3.2.1) - **Flexural strength** (modulus of rupture) for pavements and slabs - **Modulus of elasticity** where specified - **Rebar yield strength** grade (Grade 60 = 60 ksi, Grade 75, Grade 80) - **Rebar size and spacing** vs structural drawings - **Concrete cover** dimensions per ACI 318 Table 20.6.1 - **Fiber dosage rate** (lb/cy) for fiber-reinforced concrete - **Shrinkage limit** (ASTM C157 microstrain at 28 days) - **Unit weight** for lightweight concrete (typically 110-120 pcf) - **Permeability** (coulombs per ASTM C1202 for low-permeability concrete) Full guide: https://deviationcheck.com/divisions/03-concrete/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 concrete submittals: - **ACI 318** compliance documentation (Building Code Requirements for Structural Concrete) - **ASTM C39** compressive strength test reports (cylinders) - **ASTM C94/C94M** compliance for ready-mixed concrete - **ASTM C143** slump test documentation - **ASTM C231** air content test documentation - **ASTM C1602** mixing water compliance - **PCI certification** for precast concrete fabricators (categories A1, C1-C4, G, S1) - **AWS D1.4** compliance for reinforcing steel welding - **CRSI certification** for reinforcing steel fabricators - **Mill certificates (MTR)** for reinforcing steel per ASTM A615/A706 - **ASTM C157** shrinkage test reports where specified - **ASTM C1202** rapid chloride permeability test reports - **ICC-ES evaluation reports** for proprietary post-installed anchors - **Seismic certification** for precast connections (IBC/ASCE 7) - **LEED documentation** - recycled content (fly ash, slag), regional materials Full guide: https://deviationcheck.com/divisions/03-concrete/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. Applies primarily to architectural concrete: - Form finish class (as-cast, rubbed, sack-rubbed, sandblasted, bushhammered) - Exposed aggregate finish (size, color, exposure depth) - Integral concrete color (pigment dosage and color match) - Precast panel finish and texture (acid-etched, sandblasted, polished, form-liner pattern) - Concrete stain or sealer appearance (gloss level, color) - Form-liner pattern for architectural cast-in-place Full guide: https://deviationcheck.com/divisions/03-concrete/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. - **Rebar spacing** differs from structural drawings - **Lap splice length** below ACI 318 development length requirements - **Concrete cover** below specified minimum - **Joint layout** (control joints, expansion joints, construction joints) differs from drawings - **Embed plate** location, size, or anchorage differs - **Form tie** pattern or type differs (she-bolt vs snap-tie) - **Anchor bolt** size, embed depth, or edge distance differs - **Post-installed anchor** type or capacity differs from engineer's design - **Rebar coating** type differs (epoxy-coated vs galvanized vs uncoated) - **Dowel bar** size or spacing at construction joints differs - **Waterstop** type or placement differs from detail - **Vapor retarder** placement (above vs below granular base) differs Full guide: https://deviationcheck.com/divisions/03-concrete/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 03 specs: - Concrete mix design submittals with proportions and material sources - Trial batch test results (strength, slump, air content) - Reinforcing steel shop drawings (bar bending schedules, placing drawings) - Mill test reports (MTR) for reinforcing steel - Admixture product data and compatibility letters - Formwork drawings and shoring/reshoring calculations - Curing compound product data - Precast concrete shop drawings with connection details - Precast erection drawings and sequence - Post-installed anchor calculations and ICC-ES ESR - Cold weather / hot weather concreting plan - Quality control plan (testing frequency, sampling procedures) - Concrete placement plan for mass pours --- Full guide: https://deviationcheck.com/divisions/03-concrete/submittal-package-incompleteness/ ## How Division 03 deviations are graded - **Compressive strength (f'c) below spec requirement:** BLOCKER (structural capacity, building code) - **Rebar grade below spec:** BLOCKER (structural capacity per ACI 318) - **Missing ACI 318 compliance:** BLOCKER (building code requirement) - **Chloride content exceeds limit for reinforced concrete:** BLOCKER (corrosion/durability, ACI 318) - **W/cm ratio exceeds maximum for exposure class:** BLOCKER (durability per ACI 318 Table 19.3.2) - **Air content outside range for freeze-thaw exposure:** BLOCKER (durability, ACI 318) - **Missing PCI certification for precast fabricator:** BLOCKER (quality assurance for structural precast) - **Missing mill certificates for reinforcing steel:** FIX_AND_RESUBMIT (traceability) - **Concrete cover below ACI 318 minimum:** BLOCKER (durability and fire resistance) - **Form finish class mismatch for architectural concrete:** FIX_AND_RESUBMIT (aesthetic) - **Missing cold/hot weather plan where spec requires:** FIX_AND_RESUBMIT (quality assurance) - **Fiber dosage below spec minimum:** FIX_AND_RESUBMIT (crack control)
