sealing estimate task. The Division currently estimates the volume of the void space to fill, then <br />calculates the cost of the volume of cement grout required to fill the void, and the hours necessary <br />for a crew and equipment to seal. Previously the sealing tasks used an industry standard reference <br />(R. S. Means) which used different sized crew costs for sealing tasks. The Division believes the <br />current method of estimating sealing costs more closely represents actual sealing costs. <br />Some tasks that previously may have been estimated individually have been combined together <br />where logical. Other updates to the RCE include eliminating rippers on dozers if not needed for <br />the task, elimination of dump area support equipment if not warranted for a specific task, <br />elimination of unintentionally duplicated tasks, consolidation of seeding tasks where logical, <br />logical corrections to haul distances, and consolidation of mobilization and demobilization tasks. <br />Response: As noted in the Response to Item 1, the most recent CDRMS bond update (01/16/09) <br />includes adequate monies under Tasks 069 and 071 to address reclamation of the existing Coal Refuse <br />Disposal Area. The accepted bonding estimate for the CRDA Expansion (TR09-67) provides for <br />sufficient additional monies to address reclamation of the initial phase of the CRDA Expansion. <br />Approval of TR09-67 resulted in a total calculated bond liability of $8,429,576.04. <br />TCC has posted a number of bond riders, addressing TR09-67 and subsequently approved revisions <br />(for 2009, included TR's 61, 62, 65, and 66, and MR's 234, 235, 236, 237, and 238), increasing the <br />amount of bond held by the CDRMS to a present figure of $8,563,089.00.
