This tested and PROVEN model is based on Halbert Powers Gillette and Richard Turner Dana’s 1909 book “Cost Keeping and Management Engineering: A Treatise for Engineers, Contractors, and Superintendents Engaged in the Management of Engineering Construction. https://books.google.com.sg/books/about/Cost_Keeping_and_Management_Engineering.html?id=zO-ADudj-R8C&redir_esc=y

This application of EVM is still in use today by anyone who “cost, prices, bids and bills” for work based on the “Unit in Place” method.

The only two major differences that I can see are:
1) When we set up the system for Freeport, we did not use an S-Curve but simply took the Annual CAPEX or OPEX budget and allocated it over the fiscal year (Approved Budget/365 days/3 shifts = per shift BCWS). This produced a single straight line, not an S Curve. (No ED/LD Curves)
2) In support of eventual BIM implementation, we adopted CSI’s Omniclass as the STANDARDIZED WBS/CBS coding structures. (Tables 21 and 22)

And the only ENABLER that was necessary to make this work was Freeport had an accounting system that supported the use of Activity Based Costing. Using ABC/ABM we were able to generate online progress reports within 2-3 hours after the close of each shift and we were able to report “traditional” EVM metrics at the Program, Individual Projects, Shift and even Crew Level. We were also able to report process control and process capability using 3 Sigma SPC charts. (Go HERE https://build-project-management-competency.com/1-4-1-11-unit-11/ and see Figures 15-21, Figures 43-49 and the Case Study from Figure 88.

I can only urge AACE to stop looking ONLY at how the US Government uses Earned Value by going back to our Cost Engineering Roots and embracing EVM as it evolved on the factory floors of 18th Century Industrial Revolution as a “pay for performance” or “incentive payment scheme”.
