DESCRIPTION

Cost overruns can sink even the best-engineered mega-projects β€” so what actually separates a reliable cost estimate from a dangerous guess? In this episode of Molecules to Market, host Nicolas sits down with Ashok Sinha, a cost management and project controls executive with over four decades of experience overseeing capital projects worth more than $3 billion annually across nuclear power, oil and gas, refining, petrochemicals, LNG, mining, and infrastructure.

Ashok shares the moving personal story behind his company, Archit Business Solutions, breaks down the AACE International classes of cost estimates, and explains exactly why projects blow past budget β€” from undefined scope of work to skipped earned value management. He also walks through his own cost-estimating software, "Project Estimates in Seconds," built during COVID and now used by a major Canadian utility for real class 4/5 estimates in minutes instead of months.

The conversation closes with a preview of an exciting collaboration: applying Ashok's cost-estimating tools to Portfolio Planning Plus's upcoming model refinery project in India, developed together with previous guest Sanjay Gupta.
