Extreme order-of-magnitude estimating
Simpson, T.
Extreme order-of-magnitude estimating - 2003 - Cost Engineer 41(2) March 2003, 14-16(3) .
Gives a definition of order-of-magnitude estimating as a quick method of determining an approximate probable cost of a project without the benefit of detailed scope definition. Describes the obstacles that were encountered and overcome at the deactivisation of process facilities at the US Department of Energy's Oak Ridge Y-12 plant. This model proved there was a less than 10% variance between estimated and actual costs.
