As Cost Lead, you will own cost management across our data center portfolio — from early-stage budgeting and estimating through construction and final account. You'll set up process where it doesn't exist, build benchmarks from scratch, and serve as the Cost Lead of our delivery program. You'll work closely with project managers, A/E design teams, GCs, and other Leads to keep every project on-budget and every decision grounded in credible numbers. • Own cost planning across all project phases — from concept and pre-design through construction documents and GMP negotiation • Develop detailed estimates for civil, structural, MEP, HV/LV power, cooling, fuel systems, and shell construction • Maintain real-time cost forecasts across all active projects; track actuals vs. budget and surface variances early • Own change order review: assess scope validity, commercial accuracy, and contract entitlement before recommending approval • Prepare executive-level cost reports across the portfolio — clear, scannable, exception-based • Manage contingency tracking and cost risk registers across project phases • Lead value engineering exercises with design and construction teams to optimise cost without compromising scope or schedule • Support GC and subcontractor procurement: bid leveling, scope gap analysis, and contract negotiation input • Advise on contract structure and commercial risk allocation across delivery models • Build the cost management function from the ground up: tools, templates, workflows, and reporting cadence • Establish and maintain a unit cost benchmark database covering key DC cost categories — from $/MW to equipment and trade breakdowns • Contribute to precon planning on new sites, including order-of-magnitude estimates to support site selection and investment decisions
