We have achieved excellent safety performance across our project portfolio, with many projects completed with zero Lost Time Injuries.
Effective project controls provide the visibility and data-driven insights needed for confident decision-making on major infrastructure programmes. Altongate's Project Controls service integrates cost management, schedule management, risk management, and performance reporting into a coherent framework that supports project leadership and stakeholder communication.
Our project controls teams establish and maintain the cost and schedule baselines that underpin effective project governance. We develop cost estimates at all stages of project maturity, from initial order-of-magnitude assessments through to detailed construction estimates. Schedule development follows industry best practice, with activity networks that reflect project logic, resource loading, and critical path analysis.
Cost and schedule data are integrated within earned value management frameworks that provide early warning of performance variances and support forecasting of final outcomes. Our project controls professionals are proficient in industry-standard tools including Oracle Primavera, Microsoft Project, CostX, and bespoke data analytics platforms.
