CALS Draft Final Report (DFR) Rebuttal Documents

On July 17, 2001, at the second-to-last CALS Committee (CALSC) meeting, the CALS consultant firm Parsons Brinckerhoff (PB) distributed the CALS Draft Final Report (DFR) containing a number of inaccurate engineering, operational and cost determinations about the proposed Sky Loop/Taxi 2000 PRT system. This necessitated a detailed rebuttal by the SLC that we prepared and then distributed on September 11, 2001, two weeks before the study's conclusion on September 25th. The contents of this rebuttal, in which we challenged a large number of the errors in the DFR, are presented here. We regret that we cannot present the DFR itself, for although we have requested a copy in digital form from OKI it has not yet been sent.
