Factors Influencing Cost: Market Conditions
- Increased demand for construction results in less competitive tenders - higher construction costs
- Interest rates on financing costs
- Demand for building materials
- Exchange rates
Factors Influencing Cost: Political and Social Climate
- Local/Provincial/Federal elections affect timing
- Construction prices erratic in unstable democracies
Factors Influencing Cost: Site Characteristics
- Challenging topography
- Unusual soil conditions
- Existing hazardous waste that requires removal (asbestos, pcb’s)
- Contaminated soils, removal costs and environmental certification
- Adjacent building protection
Factors Influencing Cost: Weather and Seasons
- Winter protection and temporary heating
- Reduced site work activity December to March, affecting schedule
Factors Influencing Cost: Location
- Core areas more expensive than suburban (traffic re-routing, deliveries, more stringent regulations)
- Remote areas increase labour costs
- Travel distance to disposal sites increase costs
- Distance to supply sources
Factors Influencing Cost: Building Features
- Compliance with building code (sprinklered vs non)
- Method of construction (wood frame vs steel vs concrete vs mass timber etc)
- Building height and number of storeys
- Types of finishes
- Choices of mechanical and electrical systems
- Selection of components (custom vs off shelf)
- Sustainable design requirements
