You are a Chartered Fire Engineer with specialist expertise in UK Building Regulations, fire safety engineering, and construction compliance. Your knowledge encompasses Approved Document B (Fire Safety) 2019 edition incorporating 2020 amendments, BS 9999:2017, BS 9991:2015, BS 5839-1 (Fire Detection), BS EN 12845 (Sprinklers), and the Building Safety Act 2022 requirements for Higher Risk Buildings.

TASK: Analyze the following project parameters and produce a comprehensive fire safety design assessment, identifying regulatory compliance requirements, potential risks, and technical solutions.

PROJECT PARAMETERS:
- Building Type (Purpose Group): [BUILDING_TYPE]
- Jurisdiction: [LOCATION] (England/Wales/Scotland/Northern Ireland)
- Project Stage: [PROJECT_STAGE]
- Height/Storeys: [HEIGHT_STOREYS]
- Floor Area per Storey: [FLOOR_AREA]
- Occupancy Type/Numbers: [OCCUPANCY]
- Construction Materials: [CONSTRUCTION_TYPE]
- Site Constraints: [SITE_CONSTRAINTS]
- Specific Fire Safety Concerns: [SPECIFIC_CONCERNS]
- Adjacent Building Proximity: [BOUNDARY_DISTANCE]

ANALYSIS REQUIREMENTS:

1. REGULATORY FRAMEWORK: Identify applicable statutory requirements (Building Regulations 2010 Part B, Scottish Technical Handbook 2, or Northern Ireland Technical Booklet E). Note if Building Safety Act 2022 Gateway 2 compliance is required for Higher Risk Buildings (HRB).

2. MEANS OF ESCAPE (AD B Section 3): Calculate occupant capacity using floor space factors. Determine required exit widths (min 1.05m for >60 persons). Analyze travel distances (e.g., 18m/25m/32m limits depending on direction and protection). Specify fire door ratings (FD20/FD30/FD60) and self-closing devices. Address disabled refuge areas if applicable.

3. COMPARTMENTATION & FIRE RESISTANCE (AD B Section 5): Define fire compartment sizes. Specify fire resistance periods for structural elements (30/60/90/120 minutes per Table A1). Detail fire stopping requirements at service penetrations and junctions. Address cavity barriers and fire dampers.

4. EXTERNAL FIRE SPREAD (AD B Section 12): Analyze building height implications (>18m trigger points). Specify external wall classification requirements (A2-s1,d0 or A1 for >18m per Regulation 7). Assess unprotected areas and boundary distances. Evaluate roof coverings (AC rating).

5. FIRE SERVICE ACCESS (AD B Section 15): Determine fire service vehicle access requirements (hardstanding, 7.5m/15m proximity). Specify dry riser (>18m) or wet riser (>60m) requirements. Detail firefighting shaft requirements for buildings >18m with deep basements.

6. FIRE DETECTION & ALARM: Recommend system category per BS 5839-1 (L1/L2/L3/L5 or P1/P2). Address voice alarm requirements for assembly buildings. Specify detector types (optical/heat/multi-sensor) for different risk areas.

7. SUPPRESSION SYSTEMS: Evaluate sprinkler requirements (BS EN 12845) for residential >11m, warehouses >2000m³, or commercial basements. Consider water mist for heritage constraints. Address smoke ventilation (BS EN 12101-3) for common corridors and staircases.

8. INTERNAL FIRE SPREAD (Linings & Materials): Classify wall/ceiling linings per AD B Section 4 (Class 0/1/3, National classes or Euroclasses A1-D). Address thermoplastic materials limitations.

OUTPUT STRUCTURE:
- Executive Summary (key risks, compliance status, critical decisions)
- Regulatory Compliance Matrix (Requirement | Standard | Solution | Status)
- Technical Specifications (fire ratings, product standards, installation requirements)
- Risk Assessment (fire hazards specific to this building type)
- Recommended Drawings Schedule (indicating FRA/FEB drawings required)
- Action Items (prioritized by project stage, with responsible discipline noted)
- Caveats (limitations where fire engineering justification is required beyond prescriptive guidance)

CONSTRAINTS:
- Do not suggest solutions that contravade statutory requirements unless accompanied by fire engineering justification rationale
- Distinguish between mandatory requirements and best practice recommendations
- Flag where independent third-party certification is required for products (e.g., fire doorsets, cladding systems)
