You are an expert architectural estimator and construction cost consultant with 20+ years of experience across commercial, residential, and institutional projects. Your task is to generate a comprehensive, line-item construction budget for the project described below.

## PROJECT INPUTS
Project Name: [PROJECT_NAME]
Project Type: [PROJECT_TYPE] (e.g., commercial office, single-family residential, healthcare facility, educational campus, mixed-use development)
Location: [LOCATION] (city, state/country for regional cost adjustments)
Total Building Area: [BUILDING_AREA] (square meters or square feet)
Number of Stories: [STORIES]
Construction Quality Level: [QUALITY_LEVEL] (economy, standard, premium, luxury)
Target Completion Date: [COMPLETION_DATE]
Sustainability Requirements: [SUSTAINABILITY] (e.g., LEED Silver, Net Zero, Passive House, none)
Special Systems/Features: [SPECIAL_FEATURES] (e.g., curtain wall, MEP complexity, historic preservation, seismic base isolation)
Known Constraints: [CONSTRAINTS] (e.g., union labor, remote site, phased construction, material shortages)

## REQUIRED BUDGET STRUCTURE
Generate your response in these exact sections:

### 1. EXECUTIVE SUMMARY
- Total Project Cost (hard + soft costs)
- Cost per unit area (SF or SM)
- Comparison to regional RSMeans or local cost index
- Confidence level (High/Medium/Low) with justification

### 2. HARD COSTS (Construction)
Break down by CSI MasterFormat 2016 divisions:

**Division 00-01: General Requirements & Conditions**
- Site mobilization, temporary facilities, safety, permits, bonds, insurance

**Division 02-19: Existing Conditions & Site Work**
- Demolition, earthwork, utilities, paving, landscaping

**Division 03-06: Concrete, Masonry, Metals, Wood & Plastics**
- Foundations, structure, framing, exterior enclosure

**Division 07-08: Thermal/Moisture Protection & Openings**
- Roofing, waterproofing, insulation, windows, doors

**Division 09-14: Finishes & Interior Construction**
- Interior partitions, ceilings, flooring, specialties

**Division 21-23: Fire Suppression, Plumbing, HVAC**
- Complete MEP systems with equipment allowances

**Division 25-28: Integrated Automation, Electrical, Communications**
- Power, lighting, low voltage, security, AV, IT infrastructure

**Division 31-35: Earthwork, Exterior Improvements, Utilities**
- Site mechanical/electrical, stormwater, paving

For each division provide:
- Subtotal
- Key cost drivers
- Material vs. labor split percentage
- Notable assumptions or exclusions

### 3. SOFT COSTS
- Architectural/Engineering Fees ([PERCENTAGE]% or fixed)
- Permits, fees, and regulatory compliance
- Construction management and inspection
- Testing and commissioning
- Furniture, Fixtures, and Equipment (FF&E) if applicable
- Owner's contingency and project management

### 4. CONTINGENCY & ESCALATION
- Design development contingency (%)
- Construction contingency (%)
- Escalation to mid-construction date (%)
- Total recommended reserve

### 5. COST RISK ANALYSIS
Identify 5-7 specific risks with:
- Probability (Low/Med/High)
- Potential cost impact range
- Suggested mitigation strategy

### 6. VALUE ENGINEERING OPPORTUNITIES
Suggest 3-5 alternatives that could reduce cost 10-20% without compromising core function.

### 7. ASSUMPTIONS & EXCLUSIONS
Explicitly state what is included, what is excluded, and what data sources inform your estimates.

## PRICING METHODOLOGY
Base your estimates on:
- RSMeans 2024 or comparable regional cost data
- Location factor adjustments for [LOCATION]
- Current material market conditions (note any volatility)
- Union vs. open shop labor rates as appropriate
- Productivity factors for project complexity

If specific information is missing, make reasonable professional assumptions and FLAG them clearly with [ASSUMPTION: description].

## OUTPUT FORMAT
- Use professional formatting with clear hierarchy
- Include all numerical values with units
- Provide both summary tables and detailed narrative
- End with 3 key recommendations for budget management

Begin your response immediately with the Executive Summary.
