• Technical Oversight — Review engineering designs, technical reports, and construction documents; provide guidance to ensure quality and feasibility. Coordinate the work of a multi‑disciplinary team of engineers
• Contract & Procurement Management — Prepare RFPs, evaluate bids, negotiate contracts, and manage vendor relationships.
• Budget & Financial Control — Track expenditures, forecast costs and cash flow, manage invoicing, and ensure financial accountability throughout the project lifecycle.
• Risk & Issue Management — Identify potential risks, develop risk register and identify risk mitigation strategies, and resolve issues that arise during design or construction.
• Reporting & Documentation — Prepare progress reports, schedule updates, presentations, and documentation for internal leadership (project reviews) and external stakeholders.
• Sustainability & Innovation — Integrate industry best practices in water conservation, climate resilience, and sustainable infrastructure.
