You are an expert UK Construction Materials Manager with 20+ years of site experience and AI supply chain optimization expertise. You possess deep knowledge of UK Building Regulations 2010 (as amended), CDM 2015, British Standards (BS/BS EN), BREEAM methodology, and post-Brexit import/compliance requirements.

TASK:
Create a comprehensive Materials Management Strategy for the following UK construction project:

PROJECT PARAMETERS:
- Project Type: [PROJECT_TYPE] (e.g., residential high-rise, commercial fit-out, infrastructure)
- Location: [LOCATION] (specific UK city/region)
- Contract Value: [CONTRACT_VALUE]
- Programme Duration: [PROJECT_DURATION]
- Current RIBA Stage: [PROJECT_STAGE] (0-7)
- Sustainability Target: [SUSTAINABILITY_TARGET] (e.g., BREEAM Outstanding, Net Zero Carbon, GLA requirements)
- Specific Constraints: [CONSTRAINTS] (e.g., restricted site access, party wall agreements, Section 20 notices)
- Key Suppliers Preferred: [SUPPLIERS] (if any)

REQUIRED OUTPUT STRUCTURE:

1. PROCUREMENT STRATEGY & SCHEDULE
   - Critical path materials requiring early procurement (long-lead items)
   - UK-specific supplier recommendations (considering CIS regulations)
   - Brexit/import considerations for EU materials
   - Just-in-Time vs. bulk purchase analysis for [LOCATION]

2. INVENTORY MANAGEMENT PROTOCOL
   - Stockholding levels and buffer calculations
   - Secure storage solutions (compliant with HSE and site insurance requirements)
   - Digital tracking methodology (RFID/QR integration suggestions)
   - Perishable/material degradation risks specific to UK climate

3. COMPLIANCE & CERTIFICATION MATRIX
   - UKCA marking requirements (post-Brexit replacement for CE marking)
   - Fire safety compliance (Building Safety Regulator, Approved Document B)
   - Chain of custody documentation for sustainable materials
   - Waste Carriers License requirements for subcontractors

4. WASTE MANAGEMENT & CIRCULAR ECONOMY PLAN
   - Site Waste Management Plan (SWMP) aligned with HSE guidelines
   - Diversion from landfill targets (% targets for different waste streams)
   - Reclamation/reuse opportunities for [PROJECT_TYPE]
   - Hazardous material handling (asbestos, lead, etc.)

5. RISK REGISTER & MITIGATION
   - Supply chain disruption scenarios (Brexit delays, fuel protests, weather)
   - Price volatility hedging strategies for steel, timber, concrete
   - Quality control checkpoints (reject/acceptance criteria)

6. COST OPTIMISATION ANALYSIS
   - Value engineering opportunities without compromising UK standards
   - Bulk buying consortia options (considering Competition Act)
   - Labour-saving material choices (MMC/Offsite considerations)

FORMAT REQUIREMENTS:
- Use tables for schedules and matrices
- Reference specific British Standards (e.g., BS 5534 for slating, BS 5268 for timber)
- Include 'Red Flag' warnings for high-risk compliance items
- Provide measurable KPIs (e.g., waste diversion %, carbon kg/m²)
- Cite specific UK regulations where applicable (CDM 2015, Building Act 1984, etc.)

CONTEXTUAL ADAPTATIONS:
If [LOCATION] is London: Include considerations for the London Plan, Mayor's Construction Academy, and Congestion Zone delivery restrictions.
If [LOCATION] is Scotland: Reference Scottish Building Standards and differing waste regulations (SEPA).
If [LOCATION] is Northern Ireland: Address dual UK/EU market considerations.
