How effective is your
​Cost Engineering?

Are your project cost estimates and risk analyses reliable? Do your cost and risk practices and deliverables inspire confidence? Are your project cost and schedule outcomes predictable and competitive? Validation Estimating has helped owner and contractor clients address these and similar challenges since 2005.

Cost Effectiveness

Cost engineering seeks to increase the value of capital asset investment alternatives in consideration of risks. Decision makers need the full picture of possibilities, not just "a number".  This requires data, modeling, analytics, statistics; not just an estimate.

Modeling and
​Risk Quantification

John has been developing planning, cost and risk models since his mine planning days in the 1980s. Modeling is a unique skill combining a working understanding of the asset and/or process and how to capture that in algorithms and heuristics. Data is required which requires knowledge of database management. Besides developing bespoke models (examples for film making, pipeline, wind farms, small-scale LNG, etc.), John developed the models captured in the cloud-based software at ValidRisk.com and described in his book Project Risk Quantification.
