# Quality Management System (QMS)

## Overview

The Quality Management System is a formal, three-phase construction quality framework organized by CSI division and trade. It ensures specification compliance, minimizes rework costs, and creates comprehensive, auditable quality records for every phase of construction.

**Primary Purpose**: Convert design intent and specifications into built reality with zero defects and full documentation.

**Scope**: Applies to all trades and materials from foundation through final punch-list closeout.

**Key Outcomes**:
- Reduction in rework cost (target: <2% of contract value)
- First-Pass Inspection Rate (FPIR) above 90%
- Zero code violations at final inspection
- Complete digital quality trail for O&M handoff

---

## QMS Philosophy: Three Pillars

### 1. Prevention (Pre-Installation)

Quality built in from the beginning. Before any work starts:
- Verify all materials meet specification
- Confirm crews understand acceptance criteria
- Complete prep work to documented standards
- Ensure MEP coordination is resolved
- Review and approve all submittals
- Identify and resolve clashes before installation

**Prevention Cost**: Investment in planning, verification, and coordination = lowest cost to quality.

### 2. Conformance (Installation Monitoring)

Real-time quality control during construction:
- Daily observation by field leadership and trade foremen
- In-progress measurements and testing
- Immediate corrective action when non-conformance detected
- Photo documentation of critical phases
- Hold points verified before proceeding
- Test data recorded and trended

**Conformance Cost**: Active supervision and testing = moderate cost, prevents rework.

### 3. Documentation (Post-Installation)

Permanent quality record:
- Final inspection checklists signed and filed
- Test reports and material certs retained
- Deficiencies resolved and verified
- As-built data verified
- Warranty and startup documentation complete
- O&M team trained on quality standards

**Documentation Cost**: Low (mostly administrative), enables warranty support and operations.

## Project Intelligence Integration

When project intelligence is loaded, auto-populate QMS checklists, hold points, and inspection requirements from extracted project data instead of requiring manual lookup.

### Spec-Based Checklist Generation
Generate trade-specific checklists from specifications:
- Read `specs-quality.json` → `spec_sections[]` → for each CSI division, pull testing requirements, acceptance criteria, and QC checkpoints
- Auto-populate Phase 1/2/3 checklist items with spec-specific tolerances and methods
- Example: Division 03 spec requires 4000 PSI 28-day strength → auto-set concrete Phase 3 acceptance criteria to "28-day cylinder strength >= 4000 PSI"

### Hold Point Awareness
Auto-populate pre-installation verification requirements:
- Read `specs-quality.json` → `hold_points[]` → identify mandatory hold points for the current work phase
- Flag upcoming hold points that require Building Official or third-party inspection sign-off before proceeding
- Cross-reference `inspection-log.json` → verify hold point inspection status (scheduled/pass/fail)
- Example: HP-007 (anchor bolt survey) must clear before PEMB erection → flag if not yet passed

### Location Mapping
Resolve inspection locations to structured references:
- Read `plans-spatial.json` → `room_schedule[]` + `building_areas[]` → resolve inspection area to grid references and floor levels
- Auto-populate the inspection location field with structured grid/area/room data
- Example: "Kitchen area" → Grid C-4, Level 1, Building Area: West Wing, Room 103

### Subcontractor QC Contact
Identify the responsible QC representative for each trade:
- Read `directory.json` → `subcontractors[]` → for the trade being inspected, pull the sub's QC contact and foreman information
- Auto-populate the "Responsible Party" field on inspection checklists
- Example: CFS framing inspection → EKD QC rep: contact info from directory.json

### Historical Quality Data
Pull trending data to inform current inspections:
- Read `quality-data.json` → `quality_metrics` → pull FPIR (First-Pass Inspection Rate) trends per trade
- Read `quality-data.json` → `corrective_actions[]` → surface recurring corrective actions for the current trade
- Flag trades with FPIR below 85% for increased inspection frequency
- Example: W Principles FPIR trending at 82% → recommend additional pre-pour inspection checkpoints

### Drawing Reference
Link QC inspections to relevant construction documents:
- Read `plans-spatial.json` → `sheet_cross_references[]` → match the inspection location and trade to relevant detail drawings
- Auto-populate "Reference Drawing" field on inspection checklists
- Example: Foundation rebar inspection at Grid X-2 → Reference Sheet S-1.1 (Foundation Plan), Detail 3/S-1.2

### Material Test Result Verification

```
Read quality-data.json → test_results[]
```

- Before approving any inspection involving concrete, steel, soil, or welding, check `quality-data.json → test_results[]` for the relevant material/trade
- **Concrete**: Verify 7-day and 28-day compressive strength results meet spec requirements from `specs-quality.json → acceptance_criteria[]`
- **Steel**: Verify mill test reports (MTRs) on file with correct grade and heat lot traceability
- **Soil**: Verify compaction test results meet specified percent compaction before proceeding with foundation work
- **Welding**: Verify NDT inspection results for structural connections before cover-up
- Cross-reference test specimen IDs against `procurement-log.json → delivery_tickets[]` to confirm material traceability
- Flag any test failures or pending results that could affect inspection approval
