Produce detailed cost forecasting and long-range forecasts using bottom-up and top-down techniques; identify cost to complete (CTC) and provide scenario analysis to support decision-making.
Perform rigorous variance analysis (actuals vs budget vs forecast) including root-cause investigations and actionable recommendations to project teams and senior management to protect project margin.
Manage and reconcile commitments, purchase orders, supplier invoices and subcontractor claims; ensure accruals and commitments are accurately captured in the ERP (SAP / Oracle / PeopleSoft).
Apply earned value management (EVM) principles to measure project performance (BCWP, ACWP, BAC, CPI, SPI) and prepare EVM dashboards for executive review.
Monitor change orders, contract variations and commercial exposure; coordinate with contract managers to quantify cost impact and ensure timely change order approvals and invoicing.
Control direct and indirect costs by reviewing labor productivity, material consumption, subcontractor performance and site overheads; recommend corrective actions to operations.
Drive cashflow forecasting and working capital analysis, ensuring that project cash requirements and supplier payment schedules are managed to optimize company liquidity.
Maintain and enhance cost control tools, templates and integrated models (Excel, Power BI, custom dashboards) to improve efficiency, accuracy and transparency of cost data.
Coordinate with procurement to reconcile supplier statements, validate supplier invoices against contracts and POs, and support dispute resolution to avoid cost leakage.
Implement and maintain internal controls and standard operating procedures for cost capture, coding, capital vs expense classification and month-end processes to ensure compliance with corporate policies and GAAP/IFRS.

Ensure accurate tax, depreciation and fixed asset treatment of capitalized project costs by working with tax, fixed assets and accounting teams.
Track and report on commercial KPIs such as cost variance to date, forecast variance, estimate to complete accuracy, productivity metrics and supplier performance metrics to drive accountability.

Secondary Functions

Support ad‑hoc commercial and financial modelling requests (what-if analysis, sensitivity analysis, and scenario planning) to evaluate the cost impact of decisions.
Contribute to system implementations, upgrades and data migrations for ERP and project control systems; validate cost mappings and test month-end processes.
Assist procurement and commercial teams with supplier pre-qualification analyses and cost benchmarking exercises to improve sourcing outcomes.
