About this document
Modified TFCF for Accurate Cost Estimation by sivavalai is a document available to read on EtoBox.
This document discusses the accuracy of using a modified total field cost factor (TFCF) for conceptual estimates and checking estimates prepared by others. It presents two case studies where the modified TFCF approach produced good results. For a small carbon steel plant handling simple hydrocarbons with minimal instrumentation and pressurizing vessels, the modified TFCF was $82K rather than the original $149K, and the final cost was only 8% higher than the check estimate. While only two examples are given,
