When Complexity Slows Progress

Capital projects are inherently complex—balancing cost, schedule, technical viability, regulatory demands, and stakeholder alignment is no small task. From inconsistent designs and unclear estimates to safety concerns and regulatory exposure, even the best-prepared teams can face costly setbacks. When the stakes are high, you need more than just internal oversight. You need a partner who can shine a light on the execution unknowns and validate your path forward.
