Demolition of the pumpstation (DMG Task 20a - $55,547) is discussed in TR-12 <br />as is the general topic of buffer areas (DMG Task 20g - $3159). The remaining <br />parts of Task 20 (20b, 20c, 20d, 20e, 20f) should be deleted, reducing the total FW <br />cost for these line items from $95,900 to $0. <br />3.8 Henderson 2000 Overland Conveyor Components -DMG #24 <br />The overland conveyor system, part of the Henderson 2000 project, was <br />incorporated into the Henderson Permit through approval of AM-03. This <br />component of the Permit and of the FW was added as Area 24. Unlike other <br />e-ements of the Permit, approval of AM-03 also incorporated conditions of the U.S. <br />Forest Service (USES) relative to the land exchange required at that time. <br />Changes to USES conditions are not being proposed herein. However, using "as- <br />built" data and more recent costing experience, Henderson has revisited the <br />costing estimates initially derived for, and approved under, AM-03 (the cost <br />estimates included in DMG's FW calcuM4b11~). In reviewing the AM-03 cost <br />estimates, Henderson evaluated the contglyQr system in its entirety. Demolition <br />costs were based upon $0.13 per cubic foot of material as per Climax and TR-12. <br />Likewise, non-hazardous solid waste materials will be buried on site rather than <br />hauled off-site to a public landfill. This issue also was addressed in TR-12. <br />The cost of DMG Task 24e, compacting and covering the demolished snowshed, <br />was recalculated by EEE to be $18,075, an increase of $2125. The cost of DMG <br />Task 24c, removal of conveyor foundations from the wetlands, was removed <br />because the U.S. Army Corps of Engineers 404 Permit for this site requires that <br />foundations be left in place. <br />Revised estimates were calculated by EEE. EEE also provided costing <br />calculations to Climax used in development of the FW for that site. EEE's <br />complete report including all supporting data, calculations and sketches, is <br />included in Exhibit H. A summary of estimated demolition costs, including unit <br />costs and references, for the entire conveyor system is found in Exhibit H, Table 1. <br />Structural demolition of the Henderson conveyor system including compacting <br />and covering the snowshed (DMG Tasks 24a and 24e) were estimated to cost a <br />total of $1,484,149 (adjusted for location). Henderson's new estimate based on <br />the data provided by EEE is $251,787 (adjusted for location), a reduction in the <br />total FW of $1,232,362. <br />t0 <br />
