Applying Quality Management & Lean Six Sigma in the RFP Phase: Wastewater Treatment Plant Design (Ontario, Canada)

What this presentation covers

Key Takeaways

• Ontario regulatory framework: Environment Canada standards, Ontario Water Resources Act, municipal bylaws, and professional engineering codes
• Bid evaluation timeline: RFP development (2-3 months), bid submission (30-60 days), technical evaluation (3-4 weeks), financial assessment (2-3 weeks), contract award (2-4 weeks)
• Scoring matrix: Technical Criteria 60% (process design 25%, compliance 15%, innovation 10%, energy efficiency 10%), Financial 30%, Qualifications 10%
• Risk assessment frameworks: probability-impact matrix, critical path analysis, compliance checklists, and Monte Carlo simulation for cost overrun analysis
• Common deficiencies: incomplete hydraulic modeling, inadequate cold-weather design, insufficient future capacity planning, lack of power redundancy
• Case study: Ashbridges Bay Treatment Plant Upgrade — $350M, 818,000 m³/day, completed 2 months ahead, 5% under budget, energy 15% below projections
• Value engineering: process-train optimization, Ontario-specific material durability, modular vs. traditional construction, emerging vs. proven technology balance
